How to load remote Modal content in yii2 - php

Question

I have been trying to load remote content for different bootstrap modal on same yii2 view
<?php
$label = $model->getAttributeLabel('educationId');
$addon = [
'prepend' => [
'content' => Html::icon('book')
],
'append' => [
'content' => Html::button(
Html::icon('plus'), [
'class' => 'btn btn-success',
'title' => 'Add New' . $label,
'onclick' => new JsExpression('showModal();'),
]
),
'asButton' => true
]
];
echo Html::tag('label',$model->getAttributeLabel('educationId'), ['class'=>'control-label']);
echo Select2::widget([
'model' => $model,
'attribute' => 'educationId',
'data' => ArrayHelper::map ( EducationLevel::find ()->all (), 'id', 'name' ),
'options' => ['placeholder' => 'Select Education Level ...','template' => 'label}\n{error}'],
'addon' => $addon,
'pluginOptions' => [
'maximumInputLength' => 10
],
]);
JS function
Function showModal(){
$('#addEducationModal').modal({
remote: 'modal.html',
show: true
});
}
So the user will click on the addon button of a text field and the modal will show up, and other text fields shall have same mechanism with different modal content.
However all what I get is faded background.

Answer 1

I was able to make it work and more than that.
The issue i had mainly because the yii cashes generated files so to resolve i deleted the generated files and made sure the content is generated fresh :)
and i havent used the JQuery load function.
see below code:
PHP View Code
$label = $model->getAttributeLabel('majorId');
$addon = [
'prepend' => [
'content' => Html::icon('book')
],
'append' => [
'content' => Html::button(Html::icon('plus'), [
'class' => 'btn btn-success',
'title' => 'Add New' . $label ,
'data-toggle' => 'modal',
'data-target' => '#addModal',
'href'=> 'addMajorModal.html',
]),
'asButton' => true
]
];
echo Html::tag('label',$model->getAttributeLabel('majorId'),['class'=>'control-label']);
echo Select2::widget([
'model' => $model,
'attribute' => 'majorId',
'data' =>ArrayHelper::map ( Major::find ()->all (), 'id', 'name' ),
'options' => ['placeholder' => 'Select Major ...','template' => 'label}\n{error}'],
'addon' => $addon,
'pluginOptions' => [
'maximumInputLength' => 10
],
]);
<div class="modal fade" id="addModal" >
<div class="modal-dialog" dir="rtl">
<div class="modal-content" dir="rtl">
<!-- Content will be loaded here from "addMajorModal.html" file -->
</div>
</div>
</div>
The Modal file content
<div class="modal-header panel-primary" dir="rtl" horizantal-aligned="">
<button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button>
<h4 class="modal-title" id="myModalLabel">إضا�ة جديد</h4>
</div>
<div class="modal-body" dir="rtl">
<div id="login-boxs" class="login-popup>
<form id="newCat" method="post" class="signin" dir="rtl" action="#">
<div class="form-group">
<label for="certName" class="control-label">مسمى التخصص </label>
<input type="text" name="name" data-val="true" data-val-required="ErrMsg" data-rule-required="true" placeholder="مسمى الشهادة" class="form-control" id="certName">
</div>
<div class="form-group">
<label for="certShortDesc" class="control-label">وص� قصير </label>
<input type="text" name="shdesc" data-rule-required="true" placeholder="وص� قصير" class="form-control" id="certShortDesc" required>
</div>
</form>
</div>
</div>
<div class="modal-footer" dir="rtl">
<div class="col-lg-6" dir="rtl">
<div class="progress" >
<div class="progress-bar progress-bar-striped" role="progressbar" aria-valuenow="60" aria-valuemin="0" aria-valuemax="100" style="width: 100%;" id="progresBarUpload">
</div>
</div>
</div>
<div class="col-lg-6" dir="rtl">
<button type="button" class="btn btn-danger" dir="rtl" data-dismiss="modal"><i class="glyphicon glyphicon-remove"> </i>Close</button>
<button id="submitButton" type="button" dir="rtl" class="btn btn-primary" onclick="createCertificate()"><i class="glyphicon glyphicon-ok"> </i>Save changes</button>
</div>
</div>
Thats all, with this the modal will be loaded based on yii append generation of the HTML
As far as i know, this will be workable till Bootstrap 3.3 as remote content will be deprecated in version 4
