Get Value of dropdown list in jquery entity field - javascript

I want to get a specific value of drowpdown list using jquery and symfony
my code in formType given as follow
->add(
'predefinedMessage',
'entity',
array(
'empty_value' => 'Ajouter un message Prédéfini',
'class' => 'ACMBundle:Message',
'property' => 'name',
'multiple' => false,
'error_bubbling' => true,
'required' => false,
'query_builder' => function (EntityRepository $er) use ($user) {
return $er->createQueryBuilder('u')
->where('u.user = :user')
->setParameter('user', $user);
},
)
)
the entity Message has many fields: id, name, message, userid
I have a text area in my twig
{{ form_widget(form.message,{ 'attr': {'maxlength': '50','placeholder':'placeholder.message.message'|trans} }) }}
in my jquery
<script>
$('#add').click(function(){
var text="{{form.predefinedMessage.vars.data.message }}";
$('#Pushtype_message').val(text);
});
the value of message added to the text area, but when I select the other option, the value in the text area still the same.
consider I have an entity message which contain two line data
id:1 ,userid: 1 , name: message1, message: first message
id:2, userid: 2 , name:message2, message : second message

Dynamically changing form is Symfony 5

I am trying to make a form that changes based on user response, I have a ChoiceType::class for the first part with 'yes' or 'no' as the options. If the user selects 'yes' I want the second part of the form to show up to get their response to that, but if they select 'no' I just want to keep that second form hidden.
This is the form I have so far
public function buildForm(FormBuilderInterface $builder, array $options)
{
->add('attending', ChoiceType::class, [
'choices' => [
'yes' => true,
'no' => false,
],
'attr' => [
'class' => 'attendanceStatus'
],
'mapped' => false,
'required' => true,
'label' => 'Will you be attending?',
'placeholder' => 'Please make selection',
])
->add('bringingGuest', ChoiceType::class, [
'choices' => [
'yes' => true,
'no' => false,
],
I wrapped the forms in a class and gave each form an ID
<div class="attendance">
<div id="attendance-status">
{{ form_label(form.attending) }}
{{ form_errors(form.attending) }}
{{ form_widget(form.attending) }}
</div>
<div id="guest" style="display: none;">
{{ form_label(form.bringingGuest) }}
{{ form_errors(form.bringingGuest) }}
{{ form_widget(form.bringingGuest) }}
</div>
</div>
I'm not the greatest with javascript but I tried to do an if statement like this
if ('.attending' == true) {
document.getElementById('guest').style.display = 'block';
}
I've been at this for a bit of time now and I can't seem to figure out how to do it properly. I thought it would be something like having an event listener for the user selection and then just using javascript to show the second form if conditions are met.
This is, like you probably already know, a javascript question. Like you said, you can use an event listener, for example to run a function whenever a value changes. Here's an example:
const someId = document.getElementById('some-id');
const example = document.getElementById('example');
someId.addEventListener('change', doSomething);
function doSomething() {
if (someId.value === "yes") {
example.innerHTML = "YES!"
} else {
example.innerHTML = ""
}
}
<select name="name" id="some-id">
<option value="no">no</option>
<option value="yes">yes</option>
</select>
<div id="example">
</div>
All you need to do is check what IDs you should target and what you want to happen on which event. To find out more about events, see: https://developer.mozilla.org/en-US/docs/Web/Events.
You may want to check How to Dynamically Modify Forms Using Form Events page in Symfony docs.
In your case it will be Dynamic Generation for Submitted Forms section.
It involves 2 types of events - Form events on PHP/Symfony side and JS mostly "passive" role to listen for element change and replace the HTML.
The idea is next:
On user action on the HTML element send a request to backend and render the new state for the page based on the element's changed value. Here you get full page HTML as a response.
Then just replace dependent chunks of the page with the new rendered pieces of HTML you get from the response.
Here are main parts (copy-pasted from the docs):
// src/Form/Type/SportMeetupType.php
namespace App\Form\Type;
use App\Entity\Position;
use App\Entity\Sport;
use Symfony\Bridge\Doctrine\Form\Type\EntityType;
use Symfony\Component\Form\FormInterface;
// ...
class SportMeetupType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options): void
{
$builder
->add('sport', EntityType::class, [
'class' => Sport::class,
'placeholder' => '',
])
;
$formModifier = function (FormInterface $form, Sport $sport = null) {
$positions = null === $sport ? [] : $sport->getAvailablePositions();
$form->add('position', EntityType::class, [
'class' => Position::class,
'placeholder' => '',
'choices' => $positions,
]);
};
$builder->addEventListener(
FormEvents::PRE_SET_DATA,
function (FormEvent $event) use ($formModifier) {
// this would be your entity, i.e. SportMeetup
$data = $event->getData();
$formModifier($event->getForm(), $data->getSport());
}
);
$builder->get('sport')->addEventListener(
FormEvents::POST_SUBMIT,
function (FormEvent $event) use ($formModifier) {
// It's important here to fetch $event->getForm()->getData(), as
// $event->getData() will get you the client data (that is, the ID)
$sport = $event->getForm()->getData();
// since we've added the listener to the child, we'll have to pass on
// the parent to the callback functions!
$formModifier($event->getForm()->getParent(), $sport);
}
);
}
// ...
}
in JS:
{# templates/meetup/create.html.twig #}
{{ form_start(form) }}
{{ form_row(form.sport) }} {# <select id="meetup_sport" ... #}
{{ form_row(form.position) }} {# <select id="meetup_position" ... #}
{# ... #}
{{ form_end(form) }}
<script>
var $sport = $('#meetup_sport');
// When sport gets selected ...
$sport.change(function() {
// ... retrieve the corresponding form.
var $form = $(this).closest('form');
// Simulate form data, but only include the selected sport value.
var data = {};
data[$sport.attr('name')] = $sport.val();
// Submit data via AJAX to the form's action path.
$.ajax({
url : $form.attr('action'),
type: $form.attr('method'),
data : data,
success: function(html) {
// Replace current position field ...
$('#meetup_position').replaceWith(
// ... with the returned one from the AJAX response.
$(html).find('#meetup_position')
);
// Position field now displays the appropriate positions.
}
});
});
</script>

Symfony2 cascasing dropdown value change via ajax not accepting on submission

I have two entity dropdowns field in my symfony form. On the front end i change the option list of 2nd drop drown using ajax based on the value of first dropdown selected value. and Upon submitting the form i get the error that,
This value is not valid.
below is the code;
/**
* #ORM\ManyToOne(targetEntity="State")
* #ORM\JoinColumn(name="province_id", referencedColumnName="id")
*/
protected $Province;
/**
* #ORM\ManyToOne(targetEntity="District")
* #ORM\JoinColumn(name="district_id", referencedColumnName="id")
*/
protected $District;
and in the form,
->add('domicileDistrict','entity', [
'label' => ucwords('District'),
'class'=>'GeneralBundle\Entity\District',
'required' => true,
'mapped' => true,
'attr' => ['class' => 'form-control'],
'label_attr' => ['class' => 'control-label'],
])
->add('domicileProvince','entity', [
'label' => ucwords('Province'),
'class'=>'GeneralBundle\Entity\State',
'required' => true,
'attr' => ['class' => 'form-control select2'],
'label_attr' => ['class' => 'control-label'],
])
and on front end,
$("#profile_from_type_domicileProvince").change(function() {
var state = $('option:selected', this).val();
getDistrictByState(state);
});
function getDistrictByState(state){
var dict = {
type: "POST",
url: "{{ url('ajax_district_by_stateId') }}?id=" + state,
success: function(e) {
$("#profile_from_type_domicileDistrict option").remove();
$.each(e, function(e, p) {
$("#profile_from_type_domicileDistrict").append($("<option />", {
value: e,
text: p
}));
});
}
};
$.ajax(dict);
}
UPDATE: Add PRE_SUBMIT Event;
After suggestion form #Alsatian, I update my form and add the event as below, but nothing happens on selecting first dropdown.
$builder->addEventListener(FormEvents::PRE_SUBMIT, [$this, 'preSubmitData']);
public function preSubmitData(FormEvent $event){
$form = $event->getForm();
$data = $event->getData();
if (array_key_exists('Province', $data)) {
$state = $data['Province'];
$event->getForm()
->add('District','entity', [
'label' => ucwords('District'),
'class'=>'GeneralBundle\Entity\District',
'required' => true,
'mapped' => true,
'query_builder' => function(DistrictRepository $repository) use ($state) {
$qb = $repository->createQueryBuilder('d')
->andWhere('d.verified = :verified')
->andWhere('d.active = :active')
->setParameter('verified', true)
->setParameter('active', true);
if ($state instanceof State) {
$qb = $qb->where('d.state = :state')
->setParameter('state', $state);
} elseif (is_numeric($state)) {
$qb = $qb->where('d.state = :state')
->setParameter('state', $state);
} else {
$qb = $qb->where('d.state = 1');
}
return $qb;
},
'attr' => ['class' => 'form-control select2'],
'label_attr' => ['class' => 'control-label'],
]);
}
}
I had the same problem.
I wrote a bundle here to deal with "extensible" choice types (also entity or document) :
https://github.com/Alsatian67/FormBundle/blob/master/Form/Extensions/ExtensibleSubscriber.php
How I do it :
Hooking in the form submission process, we can access to the submitted entity by the PRE_SUBMIT FormEvent.
All submitted entity are loaded and are in $event->getData().
Then we have just to take this submitted choices as new 'choices' option for the field.
Caution :
Doing it so it will only validate that the entity submitted exist !
If only a part of the entities are possible choices you have to add a constraint to validate them.
You can also set the choices in the PRE_SUBMIT event, depending on the value of the first dropdown (instead of using all submitted entities).

How to get value of checked gridview column

Hi guys i have a gridview like below
and i want to get the 'user_id' of the checked column
how can i do that???
I could easily get the checked column id but i dont know how to get data of those checked column in gridview
i want to get it via javascript so that i can pass it to service
<?= GridView::widget([
'dataProvider' => $dataProvider,
'filterModel' => $searchModel,
'showOnEmpty'=>true,
'columns' => [
['class' => 'yii\grid\CheckboxColumn'],
[
'attribute' => 'event_id',
'label' => 'Event Title',
'value' => 'event.title'
],
[
'attribute' => 'user_id',
'label' => 'Email',
'value' => 'users.email',
],
'user_type',
],
]);
?>
and here is my javascript to get ids of checked column
jQuery(document).ready(function() {
btnCheck = $("#send");
btnCheck.click(function() {
var keys = $("#w0").yiiGridView("getSelectedRows");
}
});
Let me tell you the flow of this
On homepage is a gridview like this
Now user will click on that small user sign and that will open the page you can see below
Thats when i want to send messages to all selected users
Because in my case title is from different table and name and email are from different table so i want ids of user table
For that i want user_id but i am getting some random values
What can i do here???
I tried this but its returning some random string
public function search($params)
{
if(!isset($_GET['id'])){
$id='';
}
else{
$id=$_GET['id'];
}
$query = Checkin::find()->where(['event_id'=> $id]);
$query->joinWith(['event', 'users']);
$dataProvider = new ActiveDataProvider([
'query' => $query,
]);
$this->load($params);
if (!$this->validate()) {
return $dataProvider;
}
$query->andFilterWhere([
'id' => $this->id,
'created_date' => $this->created_date,
'created_by' => $this->created_by,
'updated_date' => $this->updated_date,
'updated_by' => $this->updated_by,
]);
$query->andFilterWhere(['like', 'user.email', $this->user_id]);
$query->andFilterWhere(['like', 'user_type', $this->user_type]);
$dataProvider->keys ='user_id';
return $dataProvider;
}
Update your DataProvider set $dataProvider->keys ='userId' then you will able to get all keys of user_id
data-id of GridView and get allSelectedColumns
You need to just replace this code
['class' => 'yii\grid\CheckboxColumn'],
with below code
[
'class' => 'yii\grid\CheckboxColumn',
'checkboxOptions' => function($data) {
return ['value' => $data->user_id];
},
],

Yii2 Checkbox Changes Style

I have a GridView displaying employee payslips, and beside each of their names are check boxes. Refer to the picture below:
As you can see, I also have a drop-down list. I set it in my jQuery to select the last child of the list which is my case, the April 10, 2015 - April 16, 2015 option. On page load, I can see this page (photo above) with those check boxes. I had a problem with the check boxes since when I click the header check box, it should select all of the check boxes below it. But it's not. Now, when I tried selecting another option in the drop-down list, here's what I get:
The style of the check boxes changes. And now, when I check the header check box, it's already working, selecting every check boxes below.
Here's how I display the drop-down list:
echo Select2::widget([
'name' => 'period',
'data' => $period,
'options' => [
'placeholder' => 'Select period',
'id' => 'period',
'style' => 'width: 400px; height: 34px;'
],
'pluginOptions' => [
'maximumInputLength' => 10,
],
]);
GridView:
<?php \yii\widgets\Pjax::begin(['id' => 'employee']); ?>
<?php
echo GridView::widget([
'dataProvider' => $dataProvider,
//'filterModel' => $searchModel,
'columns' => [
['class' => 'yii\grid\SerialColumn'],
['class' => 'yii\grid\CheckboxColumn',
'options' => ['class' => 'icheckbox_minimal',]
],
'fname',
'lname',
'totalEarnings',
'totalDeductions',
'netPay',
[
'label' => 'Action',
'content' => function ($model, $key, $index, $column) {
if ($model->netPay != null) {
return Html::a('View Payslip', ['view' , 'id' => $model->payslipID], ['class' => 'btn btn-success']);
}else{
return Html::a('Create Payslip', ['create-new', 'id' => $model->user_id], ['class' => 'btn btn-warning']);
}
}
]
],
]);
?>
<?php \yii\widgets\Pjax::end(); ?>
Script:
<script>
$(document).ready(function(){
$("#period option:last-child").attr('selected', 'selected');
$("#period").change( function()
{
var period = $('#period').val();
if(period != 0){
$.ajax({
url: 'index.php?r=payslip/periods',
dataType: 'json',
method: 'GET',
data: {id: period},
success: function (data, textStatus, jqXHR) {
$.pjax.reload({container:'#employee'});
//alert(data.start);
},
error: function (jqXHR, textStatus, errorThrown) {
console.log('An error occured!');
alert('Error in ajax request');
}
});
}
}
);
})
</script>
My question is, how do I preserve/maintain the style of the check boxes? And why does it change in style? And why are the styled check boxes not working?
Your checkboxes are changed with javascript to look like that.
You have 2 problems:
1) your "check all" function works just fine, you just need to refresh the status of the checkboxes afterwards. It works like this: when you click on the div that replaces the checkbox then the checkbox gets changed under it. Your problem is that you check it with the scripts so you need to trigger the div that sits on top of it to change too.
2) because you use pjax your page DOM gets changed. However because you probably change the checkboxes on "onload" of the page the new checkboxes remain unstyled. You need to run the function that changes them again after the pjax call.

Retrieve data in Select Option in Edit Page

I'm using Laravel 4. I'm having some problem. I have a users table with fields like. State, Region, Area and City, they are all in string (varchar).
Now, I have my "Edit Users" page. In edit users how can I display the users info ing State, Region etc. in a Select Dropdown? Here's my code.
{{ Form::select('state', array(
'' => 'Choose One', 1 => 'Luzon', 2 => 'Visayas', 3 => 'Mindanao'),
null,
array('class' => 'selectpicker',
'id' => 'state',
'data-live-search' => 'true',
'onchange' => 'document.getElementById("state2").value=this.options[this.selectedIndex].text'
));
}}
How can I make a value for that specific user already appeared or selected in the dropdown?
Thanks!
See if this works for you:
$states = array( 'Choose One', 'Luzon', 'Visayas', 'Mindanao' );
{{ Form::select('state',
$states,
array_search($user->State, $states ), // default value
array(
'class' => 'selectpicker',
'id' => 'state',
'data-live-search' => 'true',
'onchange' => 'document.getElementById("state2").value=this.options[this.selectedIndex].text'
));
}}
