PHP variable inside AJAX data string

Question

I get Uncaught ReferenceError: bierta (or whatever the URL var is) is not defined when I run the AJAX call below. How can I fix this?

$.ajax({
  type: "GET",
  async: false,
  url: "get-single-marker.php",
  data: "slug="+<?php echo $_GET['gt']; ?>,
  dataType: "json",
  success: function(res) {
    data = res;
  }
});

Try

data: "slug=<?php echo $_GET['gt']; ?>,

or

data:{slug:"<?php echo $_GET['gt']; ?>"},

You want something like:

data: "slug="+<?php echo json_encode($_GET['gt']); ?>,

or

data: "slug=<?php echo $_GET['gt']; ?>",

or grab the gt from the query using JavaScript.

View source to see why your version doesn't work.

Regardless of the method you use, you need to make sure you properly validate/escape the input. $_GET is untrusted stuff.

You are assigning a variable to the element here, and that is why it give you an error.

Try Following Code.

data: "slug=<?php echo $_GET['gt']; ?>",

This should work
