jQuery AJAX POST Send Variable

rated 0 times [ 25] [ 1] / answers: 1 / hits: 5441 / 10 Years ago, tue, july 1, 2014, 12:00:00

I have the following code:

  var result = confirm(You want to Subscribe to our Newsletter?);

  var emailAddress = $(#subscribeEmail).val();



  if (result == true) {



    $.ajax({

      type: 'POST',

      url: '/php/subscribeNewsletter.php',

      data: '{email: ' + emailAddress + '}',

      complete: function(r){

    alert(r.responseText);

    }



    });





  }

I believe the problem is to do with:
data: '{email: ' + emailAddress + '}',

I am receiving an empty $_POST array on the server side of things.

Pass an object literal, not a string:

data: {email: emailAddress },

jQuery will transform the object into the URL encoded key/value pairs, which will be picked up in the $_POST array on the PHP side.

Your current code is actually sending a JSON string as the raw POST data. jQuery is seeing the data type is a string, and so it doesn't do any processing, so you'd have to access the raw POST data on the PHP side and do a JSON decode to get it.
