in my html i can able to add more fields using jquery and the field am generating is check box array. i need to retrieve this in my controller.
so far i have tried
<input type="checkbox" value="1" name="washing[]" id="washing[]">
<input type="checkbox" value="1" name="dryclean[]" id="dryclean[]">
In controller
$clothtypeid = $request->input('clothtypeid');
$washing = $request->input('washing');
$pressing = $request->input('pressing');
for($i=0;$i<count($clothtypeid);$i++){
//in here how to test if the checkbox is ticked then value=1 else 0 ??
}
I expect if the checkbox is ticked then i have to make 1 else 0
Thanks in Advance
So I did a bit of digging and found this Tutorial which suggests;
Setting the input type to "checkbox" like you did there..
Keep the same name and include the '[]' at the end of the name attribute so that you have the following in your form;
<input type="checkbox" name="check_list[]" value="washing">
<input type="checkbox" name="check_list[]" value="dryclean">
Then in the controller you can get the value by doing the following;
if(!empty($request['check_list'])){
// Loop through array to get the checked values.
foreach($request['check_list'] as $item){
//do something here like;
if($item == 'washing'){ //make db operation or assign to a variable..}
else if($item == 'dryclean'){//make db operation}
}
}
This is a very basic example as you can see and I have to say that I haven't tested it yet but I believe it will work. Try it and give feedback.
EDIT: There is an answer here

does anybody knows how to reset my input type="file". I'm been using the $this->reset() to clear the property of the input type="file".
$this->reset(['type', 'name', 'institution', 'year', 'certification']);
If you don't need to use id for any other purposes you can render the input like this:
<input type="file" id="{{ rand() }}" >
Instead of using rand() you can also use some kind of counter or any other value that will change on every render. Different id will force livewire to completely replace the element with new one, thus empty. Just setting value="" won't help as input type="file" is immutable. This solution is taken from here
Here is a solution I found in TALL Stack Tips to remove filename from input field after uploading via Livewire.
https://talltips.novate.co.uk/livewire/livewire-file-uploads-using-s3#removing-filename-from-input-field-after-upload
The solution involves implementing a counter to regulate the input file id
To reset a file input in livewire I removed id from that input. And assign a null value to the value.
input without id
<label>Upload Image
<input type="file" wire:model="image" class="w-full">
</label>
to assign null value
$this->image = null;
input create two wire(wire:click and wire:model), It works.
livewire：
<input wire:click="fileClear('fileName')" wire:model="fileName" type="file" id="fileName" name="fileName" >
class:
public function fileClear($inputId)
{
$this->$inputId = "";
}
Clearing #AlexYokisama answer
Yes the easy way is using id as the following.
<input type="file" id="{{ $rand }}" >
And then in you livewire component you need to declare this public $rand
And you can use it safely in your reset function.
public $rand;
public function resetForm()
{
$this->rand++;
}
In Laravel 5.1, I need to update multiple values from checked checkbox.
I can edit some registries from a table by clicking the edit button for each registry, and that button send me to the edit view
(This is de edit view for a single registry)
With the url: http://myapp/someroute/2246/edit where 2246 is some id.
Inside that edit I can update 4 fields. One of those fields is called "my state" and can have the values 1, 2 or 3.
Now, I have to make a multi select edit feature, where I can check every row of the table that I need to update simultaneously (each have the name=someid) and then click some button called "Validate", and update for evey row only 1 field, the my state field, and the new value will be always 1 (in the picture the values are string but thats only for the view).
The question is: how can I call the method update for every id that I'm selecting in the view? every input checkbox has it's own name which is the id of the registry that I will update.
The update method just validate some values from the view and then call some myeditmethod, but in this case I will jump the update and go directly to myedit which is someting like:
public function myedit(Request $request, $id) {
$obj = Self::findOrFail($id);
$obj->fk_id_comuna = $req['fk_id_comuna'];
$obj->fk_id_user = $usuario_id;
$obj->date = \Carbon\Carbon::now();
$obj->fk_id_my_state = $estado; //THIS IS THE ONLY FIELD THAT I WILL EDIT, ALWAYS WITH THE SAME VALUE `1`
$obj->save();
I was trying the make a form for that Validate button but I don't know how to handle multiple id in one call on the edit method.
<form action="{!! route('myroute.update', ['id' => [HERE, HOW CAN I PASS MULTIPLE ID FROM THE CHECKED CHECKBOX] ]) !!}" method="POST">
<input type="submit" class="btn btn-primary pull-right" value="Validar" />
</form>
I was thinking on a javascript function which collect in a array every checked checkbox name and call the myedit method directly, without the formof the view, could be?
About passing multiple values as one Request value.
Assume you have form like this:
<form method="post">
<input type="checkbox" name="options[]" value="foo"/>foo<br/>
<input type="checkbox" name="options[]" value="bar"/>bar<br/>
<input type="checkbox" name="options[]" value="buz"/>buz<br/>
<input type="submit" value="Submit" />
</form>
Your request('options') would be an array: ["foo", "bar", "buz"].
Than you can iterate over options using foreach.
Inside your update method you can go with:
foreach ($option as request('options')) {
//put your previous code here, so it'd be applied for every option
}
In JS I did this:
var optionsChecked = [];
$('.options:checkbox:checked').each( function(){
optionsChecked .push($(this).val());
});
Then in ajax:
$.ajax({
type: 'POST',
data: {'id': optionsChecked },
etc
Then in PHP:
$all = $request->input('id');
foreach ($all as $id){
//whole obj->* = *;
$obj->save();
}
I have added a checkbox to my existing submit form that must change from value 0 to 1 if it is activated. But they dont' save the value, it's always 0.
My code:
<label class="checkbox-inline">
<input type="checkbox" id="inlineCheckbox1" value="true" name="trackingnumber"> You provide an Tracking Number
</label>
ProductController:
if ($request->trackingnumber == 'true') {
$product->trackingnumber = true;
}
What have I forgotten?
Okay i have just change the id="inlineCheckbox1" and works now
In your ProductController do
if ($request->trackingnumber == 'on') {
and set the value also to "on" in your html
and it should work
or you just simply dd($request)
in this situation try dd($request) in your controller and check what it contain in that.
Update:
Hey please put checkbox value="1" and then check what value of checkbox is there in request.
im using spring mvc framework with thymeleaf template engine
the problem is , i have 1 page with multiple check box iterated sing thymeleaf th:each iterator.When i clicked multiple check boxes i want to pass check box values to the controller method..
html content
<table>
<tr th:each="q : ${questions}">
<h3 th:text="${q.questionPattern.questionPattern}"></h3>
<div>
<p >
<input type="checkbox" class="ads_Checkbox" th:text="${q.questionName}" th:value="${q.id}" name="id"/>
</p>
</div>
</tr>
</table>
*Controller*
#RequestMapping(value = Array("/saveAssessment"), params = Array({ "save" }))
def save(#RequestParam set: String, id:Long): String = {
var userAccount: UserAccount = secService.getLoggedUserAccount
println(userAccount)
var questionSetQuestion:QuestionSetQuestion=new QuestionSetQuestion
var questionSet: QuestionSet = new QuestionSet
questionSet.setUser(userAccount)
questionSet.setSetName(set)
questionSet.setCreatedDate(new java.sql.Date(new java.util.Date().getTime))
questionSetService.addQuestionSet(questionSet)
var list2: List[Question] = questionService.findAllQuestion
var limit=list2.size
var qustn:Question=null
var a = 1;
for( a <- 1 to limit ){
println( a );
qustn= questionService.findQuestionById(a)
questionSetQuestion.setQuestion(qustn)
questionSetQuestion.setQuestionSet(questionSet)
questionSetQuestion.setCreatedDate(new java.sql.Date(new java.util.Date().getTime))
questionSetQuestionService.addQuestionSetQuestion(questionSetQuestion) } "redirect:/teacher/Assessment.html" }
I think you pretty much have it. With a checkbox, you can only send one piece of information back with the form...that being the value. So if you are trying to determine which checkboxes are checked when the user clicks the submit button, then I would have the checkboxes all use one name...like "id" (exactly like you have). Value is the actual id of the question (again like you have). Once submitted, "id" will be a String array which includes all the values of the checkboxes that were checked.
So your controller method needs to take param called "ids" mapped to parameter "id" which is a string[]. Now for each id, you can call questionService.findQuestionById.
(I'm not a Groovy guru so no code example sry :)
I have used JSTL with JSP and thymeleaf was something new. I read the THYMELEAF documentation.
There is a section which explains multi valued check boxes.
<input type="checkbox"
class="ads_Checkbox"
th:text="${q.questionName}"
th:value="${q.id}" name="id"/>
In the above code we are not binding the value to the field of the command object. Instead try doing this
<input type="checkbox"
class="ads_Checkbox"
th:text="${q.questionName}"
th:field="*{selectedQuestions}"
th:value="${q.id}" />
here the selectedQuestions is an array object present in the spring command object.
I have a form with the autocomplete attribute set to off.
Inside this form, there is a hidden input element (generated using ASP.NET MVC's Html.HiddenFor() method, but, that should be irrelevant):
<input type="hidden" value="0" name="Status" id="Status" data-val-required="The Status field is required." data-val-number="The field Status must be a number." data-val="true">
When the form is submitted, this value is incremented by one and the model is returned to the view. If I write the status value to the page, I can see that the value was correctly incremented.
However, this hidden input field is always cached. It's never getting the correct value. I tried setting the autocomplete attribute directly on the input element, but without success.
How can I get this hidden field to get the correct value? I'd prefer not to use any Javascript.
Edit: Supplying more code...
Controller
//This code is being executed, and the status is being incremented.
shippingOrder.Status = (shippingOrder.Status != (int)OrderStatus.Closed) ? shippingOrder.Status + 1 : shippingOrder.Status;
View
#using (Html.BeginForm("Number", "Order", FormMethod.Post, new { id = "orderSummary", autocomplete = "off" })) {
...
#Html.HiddenFor(m => m.Status)
}
According to this post here html helpers such as HiddenFor will always first use the posted value and after that the value in the model.
As you said, when writing the value to the page you can see it incremented, yet the helper is using the previously posted value, which is the intended behaviour.
The link does suggest the use of ModelState.Remove("Status") or ModelState.Clear() before assigning the new value.
It also suggest that another option could be not using a HiddenFor helper but instead to build the hidden field yourself. Similar to this:
<input type="hidden" name="Status" value="#Model.Status" />
Either way it looks like your problem is based on similar circumstances.
