Is there is a way to keep my modal open in Laravel after submit and save the values to db? - ajax

Question

I am uploading a file in Laravel 8 with having one bootstrap modal which works dynamically . everything is working fine but I want to improve my output more:
1) Update one of my forms through a modal without refreshing the page?
2) keep the modal open if the validation fails and print the errors to modal instead of my redirect page?
I will appreciate your time helping me.
my form for updating the file
<form action="{{ route('storefile' , $requisition->id) }}" method="POST"
enctype="multipart/form-data">
#csrf
#method('PUT')
<div class="form-group row">
<div class="col-sm-12">
<label for="title"> Account Status: </label>
<select class="form-control" name="acc_status">
<option value="0" {{ $requisition->acc_status == 0 ? 'selected' : '' }}> Inactive
</option>
<option value="1" {{ $requisition->acc_status == 1 ? 'selected' : '' }}> Active
</option>
</select>
</div>
<div class="col-sm-12 pt-4">
<label for="title"> Account document File: </label>
<div>
#if (!empty($requisition->acc_document))
<label class="badge-success">
{{ $requisition->acc_document }}
</label>
#else
<label class="badge-danger">
Nothing uploaded </label>
#endif
</div>
<input type="file" name="acc_document" class="form-control" id="acc_document" />
</div>
</div>
<div class="card-footer">
<div class="row">
<div class="col-md-6 text-left">
<input type="submit" value="Upload document" class="btn btn-primary">
</div>
</div>
</div>
</div>
</form>
my controller and route
public function uploadFile($id) {
$requisition = Requisition::find($id);
return view('requisition.createFile' , compact('requisition'));
}
public function storeFile(Request $request , $id) {
$request->validate([
'acc_status' => 'required',
'acc_document' => 'required|mimes:doc,docx,pdf,txt,zip|max:2000',
]);
$requisition = Requisition::find($id);
$requisition->acc_status = $request->get('acc_status');
$FileName = uniqid() .$request->file('acc_document')->getClientOriginalName();
$path = $request->file('acc_document')->storeAs('uploads', $FileName , 'public');
$requisition->acc_document = '/storage/' . $path;
}
$requisition->save();
//$requisition->update($request->all());
return back()
->with('success', 'Your file has been uploaded successfully.');
}
Route::get('upload/{id}', [RequisitionController::class, 'uploadFile'])->name('upload');
Route::put('requisition/{id}/files', [RequisitionController::class, 'storeFile'])->name('storefile');
and last part my modal and ajax in my index page to upload the file and popup will open
<div class="col-md-6">
<a style="display:inline-block; text-decoration:none; margin-right:10px;"
class="text-secondary" data-toggle="modal" id="mediumButton"
data-target="#mediumModal" title="upload"
data-attr="{{ route('upload' , $requisition->id) }}">
<i class="fas fa-upload"></i>
</a>
</div>
<script>
// display a modal (medium modal)
$(document).on('click', '#mediumButton', function(event) {
event.preventDefault();
let href = $(this).attr('data-attr');
$.ajax({
url: href,
beforeSend: function() {
$('#loader').show();
},
// return the result
success: function(result) {
// #if (count($errors) > 0) #endif
$('#mediumModal').modal("show");
$('#mediumBody').html(result).show();
$("#date-picker").datepicker({
changeMonth: true,
changeYear: true,
dateFormat: 'yy-mm-dd'
});
} ,
complete: function() {
$('#loader').hide();
},
error: function(jqXHR, testStatus, error) {
console.log(error);
alert("Page " + href + " cannot open. Error:" + error);
$('#loader').hide();
},
timeout: 8000
});
});
</script>
<!-- medium modal -->
<div class="modal fade" id="mediumModal" tabindex="-1" role="dialog" aria-labelledby="mediumModalLabel"
aria-hidden="true">
<div class="modal-dialog modal-dialog-centered modal-lg" role="document">
<div class="modal-content">
<div class="modal-body" id="mediumBody">
<form id="modal-form" method="get">
<div>
<!-- the result of displayed apply here -->
</div>
</form>
</div>
</div>
</div>
</div>

what I want to implement looks like enter image description here

Answer 1

There are several ways to do this kind of thing. One way to do it, is to do something like this:
Html:
<div class="modal" id="the-modal">
<form action="{{ $theAction }}" method="POST" id="the-form">
<input type="text" name="input-name" id="the-input">
<button type="submit">
</form>
<p id="the-text"></p>
</div>
In your Controller you will return an error or an 200 response, if everything is ok.
public function theAction(Request $request , $id) {
//Do stuff
if (!$error) {
return response("OK"); //This will return a 200 response
} else {
return response("An error happened", 500); //This will return a 500 error
}
}
Then, in your JS, you'll intercept form submission and then, you're going to be able to separate errors from ok messages:
<script>
$("#the-form").on('submit', function(event) {
event.preventDefault();
let theInput = $("#the-input");
$.ajax({
url: theUrl,
data: {
the-input: theInput
}
// 200 response
success: function(result) {
$("#the-text").empty();
$("#the-text").append(result.repsonse);
} ,
error: function(jqXHR, testStatus, error) {
$("#the-text").empty();
$("#the-text").append(error.response);
}
});
});
</script>
If you want to do all this stuff inside a modal, the concept is just the same: You intercept form submission, send to controller, return separate responses for errors and 200 responses, and then update manually the inputs/texts.
I did't test the code, but the concept should work.
