Get JQUERY function return in PHP

Question

I want to know if I can get the return of a JQUERY function, in PHP ?

I have this following jquery function, returning an array and I want to get this array in my PHP, in order to send it to process the data

function getItemMetaList() {
        var itemMetaArray = [];
        $('.frm_pro_form input, .frm_pro_form select, .frm_pro_form textarea').each(function(cpt){
            if($(this).attr('type') != 'hidden' && ($(this).attr("type") != "submit")) {
                console.log(cpt);
                console.log($(this).attr("name"));
                itemMetaArray.push($(this).attr("name"));
            }
        });
        return itemMetaArray;
    }

Thanks in advance

Either use AJAX or put value in a hidden input and submit the form — RiggsFolly

The problem with AJAX is that normally you use it with PHP functions right ? I don't see how I can send JQUERY data to my PHP file with AJAX. For the input method I can't do that, I have to get the JQUERY array with a button click in my php page — Nathan30

you can send your javascript* array with ajax called in jquery like in documentation without php function — Frankich

Yeah I finally find it. I just have a problem. I send an array, but I didn't get an array in PHP, just the content of the array. Any solutions for this ? — Nathan30

function getItemMetaList() {
    var itemMetaArray = [];
    $('.frm_pro_form input, .frm_pro_form select, .frm_pro_form textarea').each(function(cpt){
        if($(this).attr('type') != 'hidden' && ($(this).attr("type") != "submit")) {
            itemMetaArray.push($(this).attr("name"));
        }
    });
    $.ajax({
       method: "POST",
       url: "some.php",
       //data: { array: itemMetaArray}
       data: JSON.stringify({ array: itemMetaArray})
    }).done(function( msg ) {
       alert( "Data Saved: " + msg );
    });
}

you can send data by this way in a php file like documented here: ajax jquery

This is what I've done, thanks for the answer. But now the only problem is to get the array in PHP. For now the only things I've done is to display the content of the array in a <p> with this " success: function(){ $('.answer').html(itemMetaArray); }" but I can't get the array data in a PHP variable.. My webpage isn't reload

I already read this topic, but without a good solution. In my network tab I can see the POST request, with the content of the itemMetaArray. But the var_dump($_POST) still return an empty array...

The Ajax request returns data for JavaScript in the page loaded in your browser. The browser does not display the data automatically. The answer is captured by .done() in MacBook's example. You can put JavaScript in the done () method to display the data returned. If you wish the page to reload in your browser, Ajax is not the good way. In JavaScript, use form.submit instead. Then you can have your PHP code read the submitted data and generate a new html page and have this displayed by the browser.

Yes you're right, I saw in the "network" tab of Developper console that the "response" sub panel shows the array returned, while I see an empty array in the page
