How to assign result returned by ajax to php variable?

Question

JavaScript

I want to send an ajax request and assign the result to a php variable!

my code looks like this:

<?php
if ($friend) {
    $friendId = $friend->getAttribute('id');
    $blockedStatus = $friend->getAttribute('blocked');
    $isBlocked = Friend::STATUS_BLOCKED;

$setButtonValue = <<< JS
    var textRemove = 'Удалить с черного списка';
    var textAdd = 'Добавить в черный список';
    var spamButton = $('.to-spam-button');

    if ("$blockedStatus" == "$isBlocked") {
        spamButton.text(textRemove);
    } else {
        spamButton.text(textAdd);
    }

    function sendRequest (textAction) {
      $.ajax('/user/spam-friend', {
            type: 'POST',
            data: "blocked-status=" + "$blockedStatus" + "&friend-id=" + "$friendId",
            success: function(data) {
                spamButton.text(textAction);
            },
            error: function(data) {
                alert('error');
            }
      });
    }

    spamButton.click(function() {
      if (spamButton.text() == textAdd) {
        sendRequest(textRemove);
      } else {
        sendRequest(textAdd);
      }
    });

JS;

    $this->registerJs($setButtonValue, View::POS_LOAD);
}
?>

You need $blockedStatusto assign what the request will return. I'm trying to do it like this:

success: function(data) {
          spamButton.text(textAction);
          "$blockedStatus" = data;
    },

With this entry, the code does not work!

How to do it right?

Answer 1

1. what do you expect from this line "$blockedStatus" = data; ? Are you trying to assign a variable to a string?
2. php is executed on the server, ajax in the browser. When ajax returns something it returns it to the browser, there are html and js there are no php variables there.
