I'm working on my settings page, I want to add two different buttons to the form and do something different depending which the user clicked.

The documentation states I can create two buttons like this:

submit_button('Submit', 'primary large', 'primary', false);
submit_button( 'Delete', 'delete', 'delete', false );

However I don't understand how to differenciate when the user clicked each one, it seems that no matter which button clicked the form is submitted the same.

How can I do something different depending what button the user clicks?

The submit_button() function is a wrapper for get_submit_button(). Now that function has multiple arguments, but the most interesting for your actual problem is the 3rd argument name. It sets the HTML name attribute.

<form action="">
    <input ... etc.
    <button type="submit" name="choice-a">
</form>

Now everytime you process your form with an empty action attribute, you will point to the current request http://example.com/wp-admin/example.php. There you will be able to fetch your arguments via the super globals $_POST or $_REQUEST (which simplified is mostly a combination of $_GET and $_POST).

Then just inspect the array and do whatever you need/want to do.

  • hi @kaiser I could get the $_POST on the page by removing the action attribute, however I just tried it and the form stops working since it doesn't go to options.php. Is there a solution for that? Jan 22, 2015 at 16:26
  • use <form action="/options.php" type="post">

  • @LisandroVaccaro You maybe should update the code in your question and show your full example and what you really are trying to do. Hint: There's the "Settings API" built in.

    @Bysander Use esc_url( admin_url( 'options.php' ) ); instead :)
