WooCommerce Ajax add to cart with additional custom data

I am having some difficulties with trying to add to cart with custom data from the front end.
My current PHP from the backend is as follows - this is placed in my functions.php for my child-theme (This code is from the following post: Adding a product to cart with custom info and price - considering I am indeed a PHP-noobie):
<?php // This captures additional posted information (all sent in one array)
add_filter('woocommerce_add_cart_item_data','wdm_add_item_data',1,10);
function wdm_add_item_data($cart_item_data, $product_id) {
global $woocommerce;
$new_value = array();
$new_value['_custom_options'] = $_POST['custom_options'];
if(empty($cart_item_data)) {
return $new_value;
} else {
return array_merge($cart_item_data, $new_value);
}
}
// This captures the information from the previous function and attaches it to the item.
add_filter('woocommerce_get_cart_item_from_session', 'wdm_get_cart_items_from_session', 1, 3 );
function wdm_get_cart_items_from_session($item,$values,$key) {
if (array_key_exists( '_custom_options', $values ) ) {
$item['_custom_options'] = $values['_custom_options'];
}
return $item;
}
// This displays extra information on basket & checkout from within the added info that was attached to the item.
add_filter('woocommerce_cart_item_name','add_usr_custom_session',1,3);
function add_usr_custom_session($product_name, $values, $cart_item_key ) {
$return_string = $product_name . "<br />" . $values['_custom_options']['description'];// . "<br />" . print_r($values['_custom_options']);
return $return_string;
}
//This adds the information as meta data so that it can be seen as part of the order (to hide any meta data from the customer just start it with an underscore)
add_action('woocommerce_add_order_item_meta','wdm_add_values_to_order_item_meta',1,2);
function wdm_add_values_to_order_item_meta($item_id, $values) {
global $woocommerce,$wpdb;
wc_add_order_item_meta($item_id,'item_details',$values['_custom_options']['description']);
wc_add_order_item_meta($item_id,'customer_image',$values['_custom_options']['another_example_field']);
wc_add_order_item_meta($item_id,'_hidden_field',$values['_custom_options']['hidden_info']);
}
and then I have a button on the frontend that runs the following script when pressed - this runs on a custom wordpress post where I have scripted have done some scripting in the background that collects information based on the users actions on the post:
function cartData() {
var metaData = {
description: 'My test Description'
another_example_field: 'test'
};
var activeVariationId = 10335;
var data = {
action: 'wdm_add_item_data',
product_id: 10324,
"add-to-cart": 10324,
quantity: 1,
variation_id: activeVariationId,
cart_item_data: metaData
};
$.ajax({
type: 'post',
url: wc_add_to_cart_params.wc_ajax_url.toString().replace( '%%endpoint%%', 'add-to-cart' ),
data: data,
beforeSend: function (response) {
//$thisbutton.removeClass('added').addClass('loading');
},
complete: function (response) {
//$thisbutton.addClass('added').removeClass('loading');
},
success: function (response) {
if (response.error & response.product_url) {
window.location = response.product_url;
return;
} else {
alert('ajax response recieved');
jQuery( document.body ).trigger( 'added_to_cart', [ response.fragments, response.cart_hash ] );
}
},
});
}
Unfortunately this only seems to add my current variation of the product to the to cart without any more custom information. Any help with nesting in this issue would be highly appreciated. If you need any more information and/or code examples I'd be happy to supply it :)

I think that I might have solved it, or at least parts of it with this PHP (this is really just a small modification of this code - adding $cart_item_data https://quadmenu.com/add-to-cart-with-woocommerce-and-ajax-step-by-step/):
add_action('wp_ajax_woocommerce_ajax_add_to_cart', 'woocommerce_ajax_add_to_cart');
add_action('wp_ajax_nopriv_woocommerce_ajax_add_to_cart', 'woocommerce_ajax_add_to_cart');
function woocommerce_ajax_add_to_cart() {
$product_id = apply_filters('woocommerce_add_to_cart_product_id', absint($_POST['product_id']));
$quantity = empty($_POST['quantity']) ? 1 : wc_stock_amount($_POST['quantity']);
$variation_id = absint($_POST['variation_id']);
// This is where you extra meta-data goes in
$cart_item_data = $_POST['meta'];
$passed_validation = apply_filters('woocommerce_add_to_cart_validation', true, $product_id, $quantity);
$product_status = get_post_status($product_id);
// Remember to add $cart_item_data to WC->cart->add_to_cart
if ($passed_validation && WC()->cart->add_to_cart($product_id, $quantity, $variation_id, $cart_item_data) && 'publish' === $product_status) {
do_action('woocommerce_ajax_added_to_cart', $product_id);
if ('yes' === get_option('woocommerce_cart_redirect_after_add')) {
wc_add_to_cart_message(array($product_id => $quantity), true);
}
WC_AJAX :: get_refreshed_fragments();
} else {
$data = array(
'error' => true,
'product_url' => apply_filters('woocommerce_cart_redirect_after_error', get_permalink($product_id), $product_id));
echo wp_send_json($data);
}
wp_die();
}
Where this is part of the JS-function:
var data = {
action: 'woocommerce_ajax_add_to_cart',
product_id: 10324,
quantity: 1,
variation_id: activeVariationId,
meta: metaData
};
$.ajax({
type: 'post',
url: wc_add_to_cart_params.ajax_url,
data: data, ...........
I am going to have to test it some more, as it seems now that all the data-fields also gets posted in the cart, email etc - I probably have to rewrite something so that some parts of it is hidden for the "non-admin", but available for me later on + adding custom product thumbnail on add to cart.

Yii2 Javascript fail to print

This is my form field.
As can see, there is a div tag with details id right below the form field. I wanted to print the content inside the div tag out whenever I select the contact.
$url2 = yii\helpers\Url::toRoute('op-client/contact');
$this->registerJs($this->render('script2.js'), \yii\web\VIEW::POS_READY);
$form->field($model, 'contact_id')->widget(Select2::classname(), [
'data' => $getcontact,
'language' => 'en',
'options' => ['placeholder' => 'Select'],
'pluginOptions' => [
'allowClear' => true
],
'pluginEvents' =>
[
'change' => 'function()
{
var contactid = $(this).val();
getDetails(contactid);
"'.$url2.'"
}',
],
]).'
<div id="details">
</div>
Script2.js
function getDetails(contactid,url2)
{
var csrfToken = $('meta[name="csrf-token"]').attr("content");
console.log(contactid);
$.ajax({
type:"POST",
cache:false,
url:url2,
data:{contactid:contactid, _crsf:csrfToken},
success:function(data){
$("#details").html(data);
//document.getElementById("details").innerHTML = data;
},
})
}
Controller
public function actionContact()
{
$request = Yii::$app->request;
$contact = $request->post('contactid');
$contacts =OpContact::find()
->where(['id'=>$contact])
->one();
echo $contacts->name;
}
The problem seems like I cant print out the contact name. I can get the correct contact id but I cant print out the name inside the div tag, it just show blank onchange. Is there anything wrong with my calling method? Thanks

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).

wordpress custom query - orderby title will not work

I am having a problem getting a custom query to alphabetize. It keeps defaulting to displaying in the order of the date it was posted. Below is my php function.
function json_info2() {
// The $_REQUEST contains all the data sent via ajax
if ( isset($_REQUEST) ) {
$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
// get values for all three drop-down menus
$status = $_REQUEST['status'];
$industry = $_REQUEST['services'];
$state = $_REQUEST['state'];
// array of values for each of the three drop-downs
$statusAll = array('complete','incomplete');
$industryAll = array('mining','textile','machinery');
$statesAll = array('SC','TX','WA');
// set $statusArray dependent on whether or not "all" is selected in the dropdown menu
if($status == "all") {
$statusArray = array( 'key' => 'status', 'value' => $statusAll, 'compare' => 'IN');
} else {
$statusArray = array( 'key' => 'status', 'value' => $status, 'compare' => '=');
}
if($industry == "all") {
$industryArray = array( 'key' => 'industry', 'value' => $industryAll, 'compare' => 'IN');
} else {
$industryArray = array( 'key' => 'industry', 'value' => $industry, 'compare' => '=');
}
if($state == "all") {
$stateArray = array( 'key' => 'state', 'value' => $statesAll, 'compare' => 'IN');
} else {
$stateArray = array( 'key' => 'state', 'value' => $state, 'compare' => '=');
}
$pages = array(
'post_type' => 'page',
'orderby' => 'title',
'order' => 'ASC',
'paged' => $paged,
'posts_per_page' => 5,
'meta_query' => array(
'relation' => 'AND',
$statusArray,
$industryArray,
$stateArray,
array(
'key' => '_wp_page_template',
'value' => 'template-individual-project.php',
'compare' => '='
)
)
);
// query results by page template
$my_query = new WP_Query($pages);
if($my_query->have_posts()) :
while($my_query->have_posts()) :
$my_query->the_post();
<li>
<?php the_title(); ?>
</li>
<?php
endwhile;endif;
wp_reset_query();
} // end of isset
?>
<?php
die();
}
add_action( 'wp_ajax_json_info2', 'json_info2' );
add_action( 'wp_ajax_nopriv_json_info2', 'json_info2' );
?>
This above function is called by the ajax function that follows:
function do_ajax() {
// Get values from all three dropdown menus
var state = $('#states').val();
var markets = $('#markets').val();
var services = $('#services').val();
$.ajax({
url: ajaxurl,
data: {
'action' : 'json_info2',
'state' : state,
'status' : markets,
'services' : services
},
success:function(moredata) {
// This outputs the result of the ajax request
$('#project-list').html( moredata );
$('#project-list').fadeIn();
}/*,
error: function(errorThrown){
var errorMsg = "No results match your criteria";
$('#project-list').html(errorMsg);
}*/
}); // end of ajax call
} // end of function do_ajax
Is there something simple that I'm missing here? I have a similar custom query on the page when it loads (although that initial load query doesn't have the select menu values as args), and they display in alphabetical order just fine. It's only after the ajax call to filter the list that they are no longer in order.

I have found the issue after googling the problem for quite a while. I read that some of the people who were having this problem found that their theme was using a plugin called Post Types Order. It overrides the ability to set the orderby arg.
I looked at the plugins, and sure enough, Post Types Order was there. Everything I read said that the problem could be solved by unchecking "auto sort" in the settings for the plugin. However, I did that, and orderby still didn't work. I had to completely deactivate the plugin to get orderby title to work.

get all IDs of selected checkbox in Yii using javascript

I am trying to get the IDs of all the selected check boxes in yii using JAVASCRIPT. Now i am able to get only the first element ID. Can anyone please suggest the correct code to get all the check box ID.
My View:
<input type="button" value="Multiple Host Date Entries" onclick="act();" />
<div id="grid"></div>
<?php
//zii.widgets.grid.CGridView bootstrap.widgets.TbExtendedGridView
$obj=$this->widget('bootstrap.widgets.TbExtendedGridView', array(
'id'=>'host_grid',
'dataProvider'=>$dataProvider,
'type' => 'striped bordered',
//'filter' => $model,
//'type' => 'striped bordered condensed',
//'summaryText' => false,
////'afterAjaxUpdate'=>'\'changeTRColor()\'',
//'itemView'=>'_view',
'columns'=>array(
array(
'id' => 'selectedIds',
'class' => 'CCheckBoxColumn',
'selectableRows'=>2,
'value' => '$data->host_id',
'checkBoxHtmlOptions' => array('name' => 'idList[]'),
),
array( // display 'create_time' using an expression
'name'=>'host_name',
'value'=>'$data->host_name',
),
array(
'name'=>'host_serviceid',
'value'=>'$data->host_serviceid',
),
array(
'name'=>'status',
'value'=>'$data->status',
),
array(
'class'=>'CButtonColumn',
'template'=>'{edit_date}{update}{delete}',
'htmlOptions'=>array('width'=>'95px'),
'buttons' => array(
'update'=> array(
'label' => 'Update',
'imageUrl' => Yii::app()->baseUrl.'/images/icons/a.png',
),
'delete'=> array(
'label' => 'Delete',
'imageUrl' => Yii::app()->baseUrl.'/images/icons/d.png',
),
'edit_date' => array( //the name {reply} must be same
'label' => 'Add Date', // text label of the button
'url' => 'Yii::app()->createAbsoluteUrl("NimsoftHostsDetails/View", array("id"=>$data->host_id))', //Your URL According to your wish
'imageUrl' => Yii::app()->baseUrl.'/images/icons/m.png', // image URL of the button. If not set or false, a text link is used, The image must be 16X16 pixels
),
),)
),
))
;
?>
I must select some check boxes and click on multiple host date entries button to go to the specific controller.
My JavaScript:
function act()
{
var idList=$("input[type=checkbox]:checked").serializeArray();
var jsonStr = JSON.stringify(idList);
/* Object.keys(idList).forEach(function(key) {
console.log(key, idList[key]);
alert(idList[key]);
});*/
var a=$("input[type=checkbox]:checked").val();
alert(a);
if(idList!="")
{
if(confirm("Add Dates for multiple hosts?"))
{
var url='<?php echo $this->createUrl('Nimsoft/Date_all',array('idList'=>'val_idList')); ?>';
url=url.replace('val_idList',jsonStr);
//url=url.replace('val_idList',json_encode(idList));
//alert(url);
window.open(url);
/*$.post('Date_all',idList,function(response)
{
$.fn.yiiGridView.update("host_grid");
});*/
}
}
else
{
alert("Please Select atleast one host");
}
}
I need to pass the IDs to NIMSOFT controller so that I can have a for loop to process each one of those.

you can retrieve the checked column in client side (javasctipt):
var idArray = $(gridID).yiiGridView('getChecked', columnID);
// or
$.fn.yiiGridView.getSelection(gridID);

For all checked row ids we use this
var id = $.fn.yiiGridView.getChecked("your-grid-id", "selectedIds"); // array of seleted id's from grid
