Want to allow people to register on your site, but don’t want to be flooded with spam users? Try this:
add_action( 'register_form', 'add_register_field' );
function add_register_field() { ?>
<p>
<label><?php _e('What is the name of the ship in the TV show Firefly?') ?><br />
<input type="text" name="user_proof" id="user_proof" class="input" size="25" tabindex="20" /></label>
</p>
<?php }
add_action( 'register_post', 'add_register_field_validate', 10, 3 );
function add_register_field_validate( $sanitized_user_login, $user_email, $errors) {
if (!isset($_POST[ 'user_proof' ]) || empty($_POST[ 'user_proof' ])) {
return $errors->add( 'proofempty', '<strong>ERROR</strong>: You did not answer the proof-of-humanship question.' );
} elseif ( strtolower( $_POST[ 'user_proof' ] ) != 'serenity' ) {
return $errors->add( 'prooffail', '<strong>ERROR</strong>: You did not answer the proof-of-humanship question correctly.' );
}
}
This adds an extra box to the register screen with the question “What is the name of the ship in the TV show Firefly?” The user-provided answer is then compared to the official answer. If correct, the user is registered, otherwise WordPress-friendly error(s) are returned.
This is a great post. This should really be in the WP Codex. It’s far too important to have to spend a chunk of time trying to find…
Great post!
Where did you insert this code? In the wp_login.php?
Can you show exactly where this code must be placed?
The easiest way to use this code it to place it in a php file (don’t forget to add an opening
<phptag) and put that php file inwp-content/mu-plugins. That directory isn’t created by default, so you may to create it yourself. However WordPress will automatically execute any php files in mu-plugins, so you don’t have to activate or don anything from there.This is exactly what i want to achieve for a user side form I’ve made, but the coding is obviously set up for the reg form. How do I change this to slot into a user form I’ve created using a page template?
You should provide more info on your article. The way it’s written is like “I’m going to give some basic info, let them do the rest by themselves, I don’t care.”
