Laravel 4: Link to Destroy Method - laravel-4

Is there any way to change a method to DELETE when you are simply linking to the controller's #destroy method?
The following does not work:
$s = '';
Now if I do this with the #edit method it takes me to the appropriate method because edit uses GET. I'm assuming this has something to do with routing but I am not quite sure how to go about it and haven't found a clear answer yet.

If you're using resourceful routing and want to access the DELETE method in your controller, you'll need to use a form.
echo Form::open(array('url' => 'foo/bar', 'method' => 'delete'))
Will open a Laravel form and include a hidden field called _method with a value of DELETE - and this will trigger the delete method you seek.

I've been in the same situation as you and doing some research i found this than might help you like it did me
Form::macro('delete', function ($url, $button_label = 'Delete', $form_parameters = array(), $button_options = array()) {
if (empty($form_parameters)) {
$form_parameters = array(
'method' => 'DELETE',
'class' => 'delete-form',
'url' => $url
);
} else {
$form_parameters['url'] = $url;
$form_parameters['method'] = 'DELETE';
};
$button_options['type'] = 'submit';
return Form::open($form_parameters)
. Form::button($button_label, $button_options)
. Form::close();
});
It can be used in blade templates by using this
{{Form::delete('route.to.destroy.method','Button Text',['class'=>'btn btn-danger'])}}
create a file called macro.php and inculde it into the bootstrap file

Passing variable to the view from zend form using AJAX load

controller:
public function searchAction()
{
$form = new Application_Form_Search;
$k = $form->getValue('keyword');
$car = new Application_Model_Car();
$mapper = new Application_Model_CarMapper();
$this->view->cars = $mapper->search($keyword);
}
form
<?php
class Application_Form_Search extends Zend_Form {
public function init(){
$this->setMethod('post');
$this->addElement('text', 'keyword', array(
'required' => true,
'label' => 'Keyword:'
));
$this->addElement('button', 'submit', array(
'required' => false,
'ignore' => true,
'label' => 'Search'
));
}
}
?>
original view page
$(document).ready(function(){
$("#submit").click(function(){
$("#main").load('/cars/search');
});
});
Here I am trying to return the search view at the "id=main" section in the original view page by using .load()
In the search view, <?=$this->keyword?> is showing null
it seems like there's problem fetching the keyword field from the form
Ok, you need to set the second variable of .load to send the data. At present you aren't sending the data to the .load function
so it would be more like this. This is assuming that you have id of keyword
$("#main").load('/cars/search', {'keyword':$('input#keyword').val()});
or you could use
$("#main").load('/cars/search', {'keyword':$('[name="keyword"]').val()});
Please see
http://api.jquery.com/load/
Also remember to escape the value so people can't send malicious code through your form.
Hope that helps

Update / post database colum in Laravel

I have a general question.
I have a search form in larvel which returns results form the database.
in these i have an input field to enter a price if price is == 0
what my problem is when i enter price and submit it returns to the search page without my previous search results i.e it doesn't refresh the same page with results and the newly updated field etc.
form in view
{{ Form::open(['action' => 'price_input'])->with($gyms) }}
{{ Form::text('enter_price', null, ['class' => 'form-control', 'size' => '50', 'id' => 'enter_price', 'autocomplete' => 'on', 'runat' => 'server', 'required' => 'required', 'placeholder' => 'enter price!', 'style' => 'margin-bottom: 0px!important;']) }}
{{ Form::submit('Search', ['class' => 'btn btn- primary', 'style' => 'margin-left: 10px;']) }}
{{ Form::close() }}
route
Route::post('/', [ //not used yet
'as' => 'price_input',
'uses' => 'PagesController#priceUpdate'
]);
Model
public function priceUpdate($gyms)
{
if (Input::has('enter_price'))
{
$price = Input::get('enter_price');
Gym::updatePrice($price);
return Redirect::back()->withInput();
}
Session::get('gyms');
return Redirect::to('pages.home') ->with('gyms', $gym);
}
not bothering with model as that works fine.
any ideas guys?
Thanks for your answer,
i have changed my controller to this
public function priceUpdate($gyms)
{
if (Input::has('enter_price'))
{
$price = Input::get('enter_price');
Gym::updatePrice($price);
$gyms = Session::get('gyms');
return Redirect::to('pages.home') ->with('gyms', $gyms);
}
$gyms = Session::get('gyms');
return Redirect::to('pages.home') ->with('gyms', $gyms);
}
but when i run it i get
Missing argument 1 for PagesController::priceUpdate()
with the $gyms being passed into the method.
if i take out the $gyms that goes away but not sure if its still being passed with session or not, sorry im a novice.
orignally i had a search box which when run returns
return View::make('pages.home')->with($data);
what is the difference between that and
return View::make('pages.home')->with($data);
when i do the above line it returns to the search page with no search options from before update the form, any ideas?
Currently, you are just retrieving an existing session and doing nothing with it. You need to do:
$gyms = Session::get('gyms');
return Redirect::to('pages.home') ->with('gyms', $gyms);
Or
return Redirect::to('pages.home')->with('gyms', Session::get('gyms'));
Then you can access the gyms in the view with $gyms.
Alternatively, you could access Session::get('gyms') in the view as well.
Also, not sure if it's just the way you pasted it here, but you have an unnecessary space before the ->with. Just wanted to make sure that's not part of the issue, too!

Get the model ID when updating a resource

I have a form that will submit a Patch request to the controller's update method.
But the update method requires to have $id, as you can see below whenever I try that I get a
No query results for model [Item]. Since the update method did not receive the $id of the model
public function update($id)
{
$item = Item::findOrFail($id);
$update = Input::all();
// some codes to save changes
return Redirect::route('items.index');
}
Another thing is that whenever I submit the form, url turns into something like this:
mw.dev/items/%7Bitems%7D
Edit
routes.php
Route::resource('items','ItemsController');
ItemController
public function edit($id)
{
$item = Item::findOrFail($id);
return View::make('items.edit')->with('item',$item);
}
I have included the code on my edit.blade.php
{{Form::open(array('route' => 'items.update', 'method'=>'patch'))}}
{{Form::text('barcode', $item->barcode, array('placeholder' => 'barcode'))}}
{{Form::text('imei',$item->imei, array('placeholder' => 'imei'))}}
{{Form::text('item_name', $item->item_name, array('placeholder' => 'item name'))}}
{{Form::submit('edit')}}
{{Form::close()}}
You have to pass the model to your view and need to pass the id parameter when generating the form. Assume that you have a User model and it's available in the view. So you may generate the form action using something like this:
// Using Form::open method with route
Form::open(array('route' => array('route.name', $user->id)))
// Using Form::model method with route
Form::model($user, array('route' => array('route.name', $user->id), 'method' => 'patch'))
// Using Form::open method with action
Form::open(array('action' => array('Controller#update', $user->id), 'method' => 'patch'))
// Using Form::open method with url
Form::open(array('url' => 'something/update/' . $user->id, 'method' => 'patch'))
Check more on Opening A Form.
The URL
mw.dev/items/%7Bitems%7D
is most likely the url-encoded form of
mw.dev/items/{items}
I suppose there is a problem in the form submission or in the <form>'s action paremeter or in the Route::* declaration in routes.php.
This could also explain why you don't get any $id upon submission.

tank Auth set_value undefined in register_form

I get the following error when click on sign up button.
Fatal error: Call to undefined function set_value() in C:\wamp\www\bdcom\www\application\views\auth\register_form.php on line 19
I am new to codeigniter framework.
following is the code in register_form.php
if ($success){
echo '<div id=success>'.$success_message.'<div>';
}else {
//show the form
$use_username = true;
if ($use_username) {
$username = array(
'name' => 'username',
'id' => 'username',
'value' => set_value('username'),
'maxlength' => $this->config->item('username_max_length', 'tank_auth'),
'size' => 30,
);
}
And this is how I load register.php in auth.php
$this->load->view('auth/register_form', $data);
Have loaded the form helper in autoloader as well. Stuck from 3 days tring to figure out what the problem is. Appreciate the help
Thanks
Check if your autoload.php has the following, if not add them, its due to form helper not being loaded.
$autoload['helper'] = array('url','form','html');
In your constructor of your controller write this:
$this->load->helper('form');

cakephp passing selection to JS Helper

I want to get the selected schoolFilter form value and place in [SELECTED VALUE HERE].
$data = $this->Js->get('#SchoolFilter')->serializeForm(array('isForm' => true, 'inline' => true));
$this->Js->get('#SchoolSchoolId')->event(
'change', $this->Js->request(
array('action' => 'assign_school_ads/', [SELECTED VALUE HERE], array(
'update' => '#results',
'data' => $data,
'async' => true,
'dataExpression' => true,
'method' => 'POST'
)
)
);
// School Filter
$schoolFilter = $this->Form->create('School', array('id' => 'SchoolFilter');
$schoolFilter .= $this->Form->input('school_id', array('label'=>'Schools', 'empty'=>'- select -');
$schoolFilter .= $this->Form->end();
I have seen variations on this question but without any clear answer, except to just forget using JS Helper. Is it possible within the context of JS Helper? And if not, can I get the value using regular JQuery, then inject it into JS Helper.
Use following code :-
$this->Js->get('#SchoolFilter');
$this->Js->event('change', $this->Js->request(array('controller'=>'put-ur-controller-ame-here','action' => 'assign_school_ads'),array('async' => true,'update' => '#results','method' => 'post','dataExpression'=>true,'data'=> $this->Js->serializeForm(array('isForm' => true,'inline' => true)))));
the serialize() function sends the form data to the php action so we can see which option was selected and decide what to update in the ajax call.
the form data will be found in $this->data in the action (just like after a form has been submited).
Don't forget to add $this->Js->writeBuffer(); in your layout just before the body closing tag. Otherwise all the ajax code will not be added to your page.
