Last week I released version 1.5 of my Simplr Registration Forms plugin. The new version includes some big fixes and requested features. Particularly, this version now supports WP Multisite and has a few addition profile fields that can be added to the default form. It also includes better security, via WP nonces, and better field validation.
But the most important change is that it includes hooks and filters that allow it to be extended by you, the user.
For instance, let’s add a field to our form that requests the user’s zip code. First, in your functions.php file create a function for displaying the field:
function sample_zip_field($form) {
$form .= '<div>';
$form .= '<label for="zip">Zip Code:</label>';
$form .= '<input type="text" name="zip" value="'.$_POST['zip'] .'"/><br/>';
$form .= '</div>';
return $form;
}
Note that this function receives the parameter $form and then returns $form. Failing to return the form will make the entire registration form disappear. To add this form to the registration use:
add_filter('simplr_add_form_fields', 'sample_zip_field');
But then we also need to make sure this data gets saved when the for gets saved. So you’ll need to create a function for that as well.
function sample_save_meta($user_id) {
if(isset($_POST['zip'])) {
add_user_meta($user_id, 'user_zip', $_POST['zip']);
}
return $user_id;
}
Note that in order for this function to work properly it has to receive the $user_id. It is also good practice to return the $user_id at the end of the function, though not necessary.
To make sure your save function is called use the hook:
add_action('simplr_profile_save_meta','sample_save_meta');
With these two “hooks”, you can customize the registration form however you want. You could even set up your field function to only display on certain pages, making it form-specific.
Finally, I’ve also added filters to the labels on the default form fields so you can change them at will. For instance, to change username to “screen name” use the following.
function sample_label_username($label) {
$label = "Screen name: ";
return $label;
}
add_filter('simplr_label_username','sample_label_username');
I hope you find the changes useful.
