I have a form which is generated in a controller before being passed to the view:
public function displayUsers(){
$html = "";
//get all users
$users = $this->entityManager->getRepository('User')->findBy(array(), array('last_name'=>'ASC'));
if($users){
$html .= '<h3>Permissions By User</h3>';
$html .= '<select class="form-control" id="permissions-username">';
foreach($users as $user){
$html .= '<option value="'.$user->getId().'">'.$user->getLastName().', '.$user->getFirstName().'</option>';
}
$html .= '</select>';
}
return View::make('admin')->with('output', $html);
}
Then in the 'admin' view, I have the following to display the form:
{{ Form::open(array('route'=>'permissions.edit', 'method' => 'GET')) }}
<div class="form-group">
#if($output)
{{ $output }}
#endif
</div>
{{ Form::submit('Edit User', ['class'=>'btn btn-warning btn-sm', 'name' => 'edit_user', 'title'=>'Edit User']) }}
{{ Form::close() }}
When I submit this form to the controller, the value of the selected option is not carried over. The output of the permissions.edit function ends up as:
{"edit_user":"Edit User"}
With a generated URL of:
*(BASE)*/permissions/%7Bpermissions%7D/edit?edit_user=Edit+User
If I create a form on the view using blade templating, this problem is resolved. However, I do not want to have all the logic of the form on my view.
It's because your select has no name, which is right now as geven below:
<select class="form-control" id="permissions-username">
Assign a name to it, for example, something like this:
<select name="permissions_username" class="form-control" id="permissions-username">
Every form element must have a name otherwise you can't access them on server side. So, now you are able to access that element on the server (in your script) using something like this (In case of Laravel):
$permissions_username = Input::get('permissions_username');
Otherwise (Using Vanilla PHP) you may use:
$permissions_username = $_GET['permissions_username'];
Because you've used GET method in the form. So, whatever you use, you need to assign a name to your form's element, it's necessary (Even with or without Laravel).

I have a select2, which lists all items of a database table. One of these items is already selected. In edit mode, how can I show the already selected item and list the rest of the items?
IN CONTROLLER:
$offertaheader = Offertaheader::find($id_offertaheader);
$clients = Client::all()->where('visibility',1)
->sortBy('nome');
return view('offertas.edit',compact('offertaheader','clients'));
IN VIEW BLADE:
<select class="form-control select2" name="id_cliente" style="width: 100%">
<optgroup label="<?php echo htmlentities(utf8_encode('CLIENTE'), 0, "UTF-8"); ?>">
<option></option>
#foreach($clients as $client)
<option value="{{$client->id}}" {{ (old('id_client', $client->id) == ($client ? $client->id : '') ? ' selected' : '') }}>{{$client->nome}}</option>
#endforeach
</select>
I want that the already selected item must be shown and at the same time the user can change it in the blade. I prefer to avoid front-end codings like jquery or ajax.
You can update using sync method, sth like this,
public function upate()
{
$todo = Todo::findOrFail($id);
$data = $request->all();
$todo->update($data);
$users = $request->users;
$users = User::find($users);
$todo->users()->sync($users);
return response()->json("success",200);
}
I am trying to pass only the posts created by the logged in user into a laravelcollective/html select drop down menu within a form.
In my code I have two examples. Using the variable example shows how I can get the dropdown select menu to show all results from the posts table. Using the variable posts in a foreach loop shows how I can return just the posts created by the logged user, but not in a select menu.
I need to have the dropdown menu function as in the form using example but displaying results of the foreach posts loop.
Controller
public function createPost()
{
$example = Post::pluck('title', 'id')->all();
$posts = Posts::all();
return view('post.create', compact('posts', 'example'));
}
Example View
<div class="form-group">
{!! Form::label('example', 'Posts:') !!}
{!! Form::select('example', ['' => 'Select'] + $example, null) !!}
</div>
Foreach Loop Posts View
#foreach($posts as $post)
#if(Auth::user()->id == $post->user_id)
{{ $post->title }} <br>
#endif
#endforeach
try $posts = Posts::where('user_id',\Auth::id())->get()->pluck('title','');. It will return only posts of logged in user.
{{ Form::select('example', $posts) }}
You are using select box wrong.
#foreach($posts as $post)
#if(Auth::user()->id == $post->user_id)
{{ $post->title }} <br>
#endif
#endforeach
I would update your controller to only return posts by the user rather than rely on the foreach check if Auth::user()->id == $post->user_id
public function createPost()
{
$posts = Posts::where('user_id', auth()->user()->id)->get();
return view('post.create', compact('posts'));
}
As a side note, your method should probably just be create() to keep inline with the standard CRUD.
Then in your blade,
<div class="form-group">
{!! Form::label('post', 'Posts:') !!}
{!! Form::select('post', ['' => 'Select'] + $posts, null) !!}
</div>
I'm using Select2 in my webapplication. I load my Select2 boxes with Ajax. When validation fails, all the inputs are filled as before except the Select2 box. How can I restore the old value after the form validation fails? My bet was using Request::old('x'), but this inserts the value (in my case an user ID) instead of the selected text. So for example the text John would become 27 in the selectbox. How can I get the text back?
<select id="customer" name="customer" class="searchselect searchselectstyle">
</select>
The js:
token = '{{csrf_token()}}';
$(".searchselect").select2({
ajax: {
dataType: "json",
type: "POST",
data: function (params) {
return {
term: params.term,
'_token': token,
'data' : function(){
var result = [];
var i = 1;
$('.searchselect').each(function(){
result[i] = $(this).val();
i++;
});
return result;
}
};
},
url: function() {
var type = $(this).attr('id');
return '/get' + type;
},
cache: false,
processResults: function (data) {
return {
results: data
};
}
}
});
Edit
The only (dirty) solution I found so far is the following:
<select id="customer" name="customer" class="searchselect searchselectstyle">
#if(Request::old('customer') != NULL)
<option value="{{Request::old('customer')}}">{{$customers->where('id', intval(Request::old('customer')))->first()->name}}</option>
#endif
</select>
$customers is a list of all customers, so this means that for each Select2 box I need to query a big list of items in order to make it work. This will be pretty inefficient if we're talking about thousands of rows per Select2 box.
I guess there must be a better solution. Who can help me?
Normally to programmatically set the value of a select2, you would expect to use the .val() method followed by a .trigger('change') call as per their documentation (and other queries like this on SO). However, select2 themselves have something in their documentation about preselecting options for remotely sourced data.
Essentially their suggestion boils down to (after initalizing your AJAX-driven <select>):
make another AJAX call to a new API endpoint using the pre-selected ID
dynamically create a new option and append to the underlying <select> from a promise function (.then()) after the AJAX call is finished
could also use some of the regular jQuery callback chaining functions for this
trigger a change event
trigger a select2:select event (and pass along the whole data object)
Assuming you're already flashing the old data to the session, Laravel provides handy access to the previously requested input in a variety of ways, notably these three:
static access via the Request class e.g. Request::old('customer') as in the OP
the global old() helper e.g. old('customer'), which returns null if no old input for the given field exists, and can have a default as a second parameter
using the old() method on the Request instance from the controller e.g. $request->old('customer')
The global helper method is more commonly suggested for use inside Blade templates as in some of the other answers here, and is useful when you don't need to manipulate the value and can just plug it straight back in, which you would with things like text inputs.
The last method probably provides you with the answer you're looking for - instead of querying the entire collection from inside of the view, you're able to either manipulate the collection from the controller (similar to the OP, but should be nicer since it's not parsing it in the view) or make another query from the controller based on the old ID and fetch the data you want without having to trawl the collection (less overhead):
$old_customer = Customer::find($request->old('customer'));
Either way, you'd have the specific data available at your fingertips (as a view variable) before the blade template processes anything.
However you choose to inject the data, it would still follow the pattern suggested by select2:
get the pre-selected data
create an option for it
trigger the appropriate events
The only difference being you don't need to fetch the data from another API endpoint (unless you want/need to for other programmatic reasons).
I end up using similar flow like your. But my blade template is using htmlcollection package.
Controller:-
Let's say you are in create() method. When validation failed, it will redirect back to the create page. From this page, you can repopulate the list.
$customer_list = [];
if(old('customer') != NULL){
$customer_list = [old('customer') => $customers->where('id', old('customer'))->first()->name];
}
Blade View:
{{ Form::select('customer', $customer_list, null, ['class' => 'searchselect searchselectstyle', 'id' => 'customer']) }}
I did it with an input hidden for the text and it works well:
This form is showed in a Popup and ajax (using Jquery-UJS)
Form:
<form action="{{ route('store_item', $order) }}" method="POST" data-remote="true">
{{ csrf_field() }}
<div class="form-group{{ $errors->has('item_id') ? ' has-error' : '' }}">
<label class="control-label col-sm-2" for="item_id">Item: </label>
<div class="col-sm-10">
<select name="item_id" class="form-control" id="item_id">
#if(old('item_id') != null)
<option value="{{ old('item_id') }}" selected="selected">
{{ old('item_title') }}
</option>
#endif
</select>
</div>
{!! $errors->first('item_id', '<p class="text-center text-danger"<strong>:message</strong></p>') !!}
</div>
<input type="hidden" id="item_title" name ="item_title" value="{{ old('item_title') }}" />
<div class="form-group{{ $errors->has('quantity') ? ' has-error' : '' }}">
<label class="control-label col-sm-2" for="quantity">Cantidad: </label>
<div class="col-sm-10">
<input name="quantity" type="number" class="form-control" id="quantity" value="{{ old('quantity') }}"/>
</div>
{!! $errors->first('quantity', '<p class="text-center text-danger"><strong>:message</strong></p>') !!}
</div>
<button type="button" class="btn btn-default" data-dismiss="modal">Cancelar</button>
<button type="submit" class="btn btn-primary" data-disable-with="Guardando...">Guardar</button>
</form>
JAVASCRIPT:
<script type="text/javascript">
$(document).ready(function(){
$('#item_id').select2({
placeholder: 'Elige un item',
ajax: {
url: '{{ route('select_item_data') }}',
dataType: 'json',
delay: 250,
processResults: function (data) {
return {
results: $.map(data, function (item) {
return {
text: item.title,
id: item.id
}
})
};
},
cache: true
}
});
$('#item_id').on('change', function(e){
var title = $(this).select2('data')[0].text;
$('#item_title').val(title);
});
});
</script>
VALIDATION IN STORE METHOD (CONTROLLER):
$validator = Validator::make($request->all(), [
'item_id' => 'required',
'quantity' => 'required'
]);
if ($validator->fails()) {
return redirect()
->route('create_item', $order)
->withInput($request->all())
->withErrors($validator);
}
It's very important to send 'withInput' and 'withErrors' in the redirection, because we are working with a popup and ajax that is created again and doesn't keep the old values.
Maybe you can try (once the ajax call has ended) :
var oldCustomer = $('#customer > option[value={{ Request::old('customer') }}]');
if (oldCustomer.length > 0) {
oldCustomer.attr('selected', 'selected');
}
Same problem; I'm using a similar solution: If the old $id is set, I get the name and I use it as a variable for the view; Note that I also forward the id because I also used this method to pre-fill the form (coming from another place), but in this case, the name only should have been used, and for the id {{ old('author_id') }} can be used in the view:
In the controller:
elseif (($request->old('author_id') !== null) && ($request->old('author_id') != '')) {
$my_author_id = $request->old('author_id');
$my_name = Author::find($my_author_id)->name;
return view('admin/url_author.create', compact('my_name', 'my_author_id'));
}
And in the view (more precisely, in a partial used for creation & edition):
#if (isset($record)) // for use in edit case with laravelcollective)
<select class="form-control js-data-author-ajax" id="author_id" name="author_id">
<option value="{{ $record->author_id }}">{{ $record->author->name }}</option>
</select>
#else
#if (isset($my_name)) // old input after validation + pre-filling cases
<select class="form-control js-data-author-ajax" id="author_id" name="author_id">
<option value="{{ $my_author_id }}">{{ $my_name }}</option>
</select>
#else // for create cases
<select class="form-control js-data-auteur-ajax" id="auteur_id" name="auteur_id">
<option></option>
</select>
#endif
#endif
Your code is bit confusing. I don't understand why you are using a POST request to get data using ajax to fill a select2 box.
Assuming the data returned using ajax call is in the below format.
[
{
"id": "Some id",
"text": "Some text"
},
{
"id": "ID 2",
"text": "Text 2"
},
]
Now what you can do is pass in an extra parameter to your ajax call as below
url: function() {
var type = $(this).attr('id');
#if(old('customer'))
return '/get' + type + '?customer='+ {{ old('customer') }};
#else
return '/get' + type;
#endif
}
Now in your controller while returning data you can throw an extra attribute selected:true for an ID matching that particular ID.
if( Request::has('customer') && Request::input('customer') == $id )
{
[
"id" => $id,
"text" => $text,
"selected" => "true"
]
}
else
{
[
"id" => $id,
"text" => $text,
]
}
If I understood you right I can recommend you to have for each your select2 box hidden input <input type="hidden" name="customer_name" value="{{old('customer_name', '')}}"> where after change event for select2 you can insert selected name (etc. John). So if validation is fails you have:
<select id="customer" name="customer" class="searchselect searchselectstyle">
#if(!is_null(old('customer')))
<option value="{{old('customer')}}">{{old('customer_name')}}
</option>
#endif
</select>
I think your own solution is pretty much correct. You say the list of $customers will get pretty big.
$customers->where('id', intval(Request::old('customer')))->first()
Do you need to have the list stored in a variable $customers? You could just search the id you want
App\Customer::where('id', intval(Request::old('customer')))->first()
Searching by id should not be inefficient. Otherwise you could send the name with the form and store it in the old request. Shown below with some (dirty) javascript.
$("#form").submit( function() {
var sel = document.getElementById("customer");
var text= sel.options[sel.selectedIndex].text;
$('<input />').attr('type', 'hidden')
.attr('name', "selected_customer_name")
.attr('value', text)
.appendTo('#form');
return true;
});
Then like yrv 16s answer:
<option value="{{old('customer')}}">{{old('selected_customer_name')}}
You could do something like this:
First in controller pass tags to view using pluck helper like below:
public function create()
{
$tags= Customer::pluck('name','name');
return view('view',compact('tags'));
}
Then in your form try this:
{!! Form::select('tag_list[]',$tags,old('tag_list'),'multiple','id'=>'tag_list']) !!}
Don't forget to call the select2 function.
$('#tag_list').select2();
And finally in controller:
public function store(ArticleRequest $request)
{
$model = new Model;
$tags=$request->input('tag_list');
$model->tag($tags);
}
Notice tag function is not a helper in Laravel, You implement it! The function takes names and attaches them to the instance of some thing.
Good Luck.
I've been able to implement the pagination and appends() on my form and it does show the proper values in the url on page 2, though it doesn't actually bring the values back into the form/query, it simply resets the actual data being searched for and displays all.
Here is my form code and the appends.
{{ Form::open(array('class' => 'stdform', 'method' => 'post', 'name' => 'all')) }}
<input type="text" name="srch_lname" class="input-large"
value="{{ Input::old('srch_lname', Session::get('srch_lname')) }}" />
<input type="text" name="srch_fname" class="input-large"
value="{{ Input::old('srch_fname', Session::get('srch_fname')) }}" />
.
.
.
<?php echo $employees->appends(array("srch_lname" => Session::get('srch_lname'),
"srch_fname" => Session::get('srch_fname') ))->links(); ?>
And my Controller
public function getIndex() {
$srch_lname = Session::get('srch_lname');
$srch_fname = Session::get('srch_fname');
$employees = vEmployees::co()->restrictions()
->where('lastname', 'LIKE', $srch_lname . '%')
->where('firstname', 'LIKE', $srch_fname . '%')
->paginate(10);
return View::make('employees.index')
->with('employees', $employees)
->with('title', 'Users');
}
public function postIndex() {
if (Input::has('btnSearch')) {
return Redirect::to('/employees')->with('search', 1)
->with('srch_lname', Input::get('srch_lname'))
->with('srch_fname', Input::get('srch_fname'));
else {
return Redirect::to('/employees');
}
}
Full Form
{{ Form::open(array('class' => 'stdform', 'method' => 'post', 'name' => 'all')) }}
<div class="stepContainer">
<div class="formwiz content">
<h4 class="widgettitle">Search for an Employee</h4>
<p>
<label>Lastname</label>
<span class="field">
<input type="text" name="srch_lname" class="input-large"
value="{{ Input::old('srch_lname', Session::get('srch_lname')) }}" />
</span>
</p>
<p>
<label>Firstname</label>
<span class="field">
<input type="text" name="srch_fname" class="input-large"
value="{{ Input::old('srch_fname', Session::get('srch_fname')) }}" />
</span>
</p>
</div>
</div>
<div class="actionBar" style="text-align: right;">
<button class="btn btn-primary" name="btnSearch" value="1">
Search for Employee(s)
</button>
</div>
{{ Form::close() }}
You need to pass your inputs to the view so that Input::old() has values to work with after the redirect from postIndex to getIndex.
in getIndex(), add to View::make()
->with('input', [ 'srch_lname'=> $srch_lname, 'srch_fname' => $srch_fname ]);
It looks like you do not have the pageSearch value in your pagination query string. Try this.
<?php echo $employees->appends(
array("btnSearch" => "1",
"srch_lname" => Session::get('srch_lname'),
"srch_fname" => Session::get('srch_fname') )
)->links(); ?>
I made a small sample but since I don't have your employees I just used the User model and commented out the filtering, just used as a test to pass and get input values.
Note the change to Input:: from Session, in getIndex() and in the form for $employees->appends(). Use Input instead of Session, I did not see anywhere in your code where you save the filter values in session variables.
I also changed the Redirect::to() to pass the parameters in the URL since it is a get method.
I tested and the filter values are passed to getIndex() and the form fields, also the inputs get properly passed by pagination links.
class EmployeeController extends BaseController
{
public
function getIndex()
{
$srch_lname = Input::get('srch_lname');
$srch_fname = Input::get('srch_fname');
$employees = User::query()
//->where('lastname', 'LIKE', $srch_lname . '%')
//->where('firstname', 'LIKE', $srch_fname . '%')
->paginate(10);
// make input available for page's form fields as old input
Session::flash('_old_input', Input::all());
return View::make('employees')
->with('employees', $employees)
->with('title', 'Users');
}
public
function postIndex()
{
if (Input::has('btnSearch'))
{
return Redirect::to('/employees?search=1&srch_lname=' . urlencode(Input::get('srch_lname')) . '&srch_fname=' . urlencode(Input::get('srch_fname')));
//return Redirect::to('/employees')->with('search', 1)
// ->with('srch_lname', Input::get('srch_lname'))
// ->with('srch_fname', Input::get('srch_fname'));
}
else
{
return Redirect::to('/employees');
}
}
}
Form and ->appends():
{{ Form::open(array('class' => 'stdform', 'method' => 'post', 'name' => 'all')) }}
<div class="stepContainer">

"srch_fname" => Input::get('srch_fname') ))->links(); ?>
I got it working! I continued to do some research and running the search through POST was really a major issue in adding that gap between the search itself and holding the data into the GET method of pagination.
I'll run through everything I did below for anyone in the future having the same issue.
I first created a Route that would direct to a new function in my EmployeesController
Route::get('emp_srch', 'EmployeesController#search');
And created the new function in the Controller
public function search() {
$srch_lname = Input::get('srch_lname');
$srch_fname = Input::get('srch_fname');
$employees = vEmployees::co()->restrictions()
->where('lastname', 'LIKE', $srch_lname . '%')
->where('firstname', 'LIKE', $srch_fname . '%')
->orderBy('lastname')
->orderBy('firstname')
->paginate(10);
Session::flash('_old_input', Input::all());
return View::make('employees.index')
->with('employees', $employees)
->with('title', 'Users')
->with('pagetitle', 'Employees')
}
It's essentially the function I had in the getIndex though rearranging the way the search was functioning I believe was the defining factor in actually getting this to work in my case.
I also changed the url on the form, which directed to my new Route. As well as changing the form so it uses the GET Method and no longer POST.
{{ Form::open(array('url' => 'emp_srch', 'class' => 'stdform', 'method' => 'get')) }}
I do want to thank vladsch and whoacowboy for helping push me in the right direction(s).
I am using Laravel Image Intervention Package with drop-zone plugin. And for sure I have installed it properly. When I try to upload images and then submit the form its showing me the following error message
"Call to a member function getClientOriginalName() on a non-object"
Even this error message showing me if i blank this input field form. In that case it is expected to me not showing me any error message as it is not mandatory field to submit the form But it did.
I have two query.
1) what's going wrong in my code
2) Right now I am trying to upload single image. For multiple images I want to store the files info as an array. In that case what would my code in controller.
Here is my live link you can check from here
http://thetoppinghouse.com/laravel/public/admin/index/create
http://laravel.io/bin/Jxmzo
Here is my controller code
public function store()
{
$validator = Validator::make($data = Input::all(), Index::$rules);
if ($validator->fails())
{
return Redirect::back()->withErrors($validator)->withInput();
}
if ($validator->passes()) {
$index = new Index;
$index->name = Input::get('name');
$index->category_ID = Input::get('category_ID');
$files = Input::file('files');
$filename = date('Y-m-d-H:i:s')."-".$files->getClientOriginalName();
$path = public_path('img/index/' . $filename);
Image::make($files->getRealPath())->save($path);
$index->files = 'img/index/'.$filename;
$index->save();
return Redirect::route('admin.index.index')->with('message', 'Index Created');
}
}
// Form Code
<ul class="post-list">
<li>
{{ Form::label('parent_ID', 'Category') }}
{{ Form::select('parent_ID',Category::lists('category_name','id'),Input::old('category'),array('class' => 'form-control input-sm', 'id' => 'parent_ID')) }}
</li>
<li>
{{ Form::label('name', 'Index Name') }}
{{ Form::text('name', null, array( 'class' => 'form-control input-sm', 'placeholder' => 'Name' )) }}
{{ $errors->first('name', '<p class="error">:message</p>' ) }}
</li>
<li>
{{ Form::label('image', 'Cover Image') }}
</li>
<div class="dropzone" id="DropzoneArea">
<div class="fallback">
<input name="files" type="file" id="files" multiple>
</div>
</div>
{{ Form::submit('Save') }}
</li>
</ul
handle the file upload with dropzone like,
var fileDropzone = new Dropzone("div#DropzoneArea", {
url: '/upload', // customize the URL
addRemoveLinks: false
});
then when u uploading something upload action will call and u can handle the file upload in that action. then you can return the server file path of uploaded file.
fileDropzone.on("success", function (file,data,e) {
var hiddenInput = $('<input name="filePath" type="hidden value=" '+ data.path +' "">');
// and append the hiddenInput in to the form
});
then after success upload you can set the server path of the uploaded file in a input hidden field. after you submit the form you can get the file by hidden field value.
when you submit the form, get uploaded file as,
$filePath = Input::input('filePath');
$file = File::get($filePath);
