Wordpress Add user by javascript

Question

I have a wordpress website en would like to create users with a button (to start with)

It works in pieces, but i can't get this two pieces to work together

i have this piece of code (works on functions.php , but not in my createaccount.php file)

 $userid = new WP_User(wp_create_user( 'My_new_name' , '123458' , '[email protected]'));
   $userid->set_role('client');  //custom role 'client' already set

this on jquery //php file works when echo 'test';

$(document).ready( function() {

   $('#newbtnaccount').click( function() {

      $.post('php/createaccount.php', { } , 
                      function(data) {

                         alert(data);

    });

  });
});

i already tried a lot of options but nothings seems to work yet.

Anyone who can Help? Thanks!

Can you include the error message in your question when you run the createaccount.php? — jehna1

So did you look at the error log on your server to see what is happening? — epascarello

Have you loaded WordPress in createaccount.php? WordPress functions won't be available to you unless you explicitly load WordPress in a custom file like this. — rnevius

i tried using global $wpdb; AND include("../../../wp-load.php"); — user2740557

In wordpress you can make an AJAX request to admin-ajax.php and attach functions in your functions.php file with wp_ajax_my_action (for logged users) and wp_ajax_nopriv_my_action (for non logged users).

1. Set the admin-ajax.php url available as JS variable

In header.php add this in the head part:

<script type="text/javascript">
var ajax_url = '<?php echo admin_url('admin-ajax.php'); ?>';
</script>

2. Request the function through ajax

You need to add an action parameter to your request reflecting the function that you need to call in functions.php - let's call it create_user.

$.post(ajax_url, {action: 'create_user'} , function(data) {
  alert(data);
});

3. Create the function in functions.php

Inside functions.php, add the following:

function ajax_create_user() {
  $userid = new WP_User(wp_create_user( 'My_new_name' , '123458' , '[email protected]'));
  $userid->set_role('client');
  // echo whatever you need to return
}
add_action( 'wp_ajax_create_user', 'ajax_create_user' );
add_action( 'wp_ajax_nopriv_create_user', 'ajax_create_user' );

Great answer. But isn't step #1 unnecessary? Why not just set the AJAX URI in the $.post() call?

vard Over a year ago

@rnevius In most cases it is unnecessary and can be safely replaced by /wp-admin/admin-ajax.php - it's just a bulletproof solution in case of specific installations (admin folder being renamed, prefix for the WP installation).

I agree with you. I was just referring to keeping things all in one place, rather than defining a variable in the head and then making the AJAX call elsewhere. I would rather use $.post('<?php echo admin_url('admin-ajax.php'); ?>', {action: 'create_user'} , function(data) { ..., but either works, of course :-)
