Register members via s2Member with a PIN

You need to build a checking function and hook it to the “create member” procedure, like this:
add_action('user_register', 'pin_check');
where “pin_check” is the name of your function. Best is to do this as a PHP file at “wp-content/mu-plugins” directory.

Thanks krumch – I appreciate you’re response but I am still lost. Also, I don’t have a mu-plugins folder, is this something I have to create? Sorry if I sound really clueless to this stuff – I just design websites and I’m not an expert at this stuff.

I want to use s2Member so members can only register if their first, last names and pin match. Otherwise, they would be denied registration.

I currently have this code that I added to my theme’s functions file with WP-Members – I also created a PIN field – but I no longer want to use WP-Members. Is there a way to do something like this with s2Member?

<?php

add_action( 'wpmem_pre_register_data', 'validate_pin' );
function validate_pin( $fields )
{

	global $wpmem_themsg, $wpdb;

	$query = 'SELECT * FROM my_table WHERE LOWER( first_name ) = LOWER( "'
		. $fields['first_name'] . '" ) AND LOWER( last_name ) = LOWER( "'
		. $fields['last_name'] . '" ) LIMIT 1';
	$result = $wpdb->get_results( $query, 'ARRAY_A' );

	if( ! $result ) {
		$wpmem_themsg = 'Sorry, that name was not found.';
		return;
	}

	foreach( $result as $the_user ) {
		$wpmem_themsg = ( $fields['pin'] != $the_user['pin'] ) ? 'Incorrect PIN!' : '';
	}

	return;
}

Just modify your code along the lines krumch suggested. In other words, change the first line so that the code reads:

<?php

add_action( 'user_register', 'validate_pin' );
function validate_pin( $fields )
{

	global $wpmem_themsg, $wpdb;

	$query = 'SELECT * FROM my_table WHERE LOWER( first_name ) = LOWER( "'
		. $fields['first_name'] . '" ) AND LOWER( last_name ) = LOWER( "'
		. $fields['last_name'] . '" ) LIMIT 1';
	$result = $wpdb->get_results( $query, 'ARRAY_A' );

	if( ! $result ) {
		$wpmem_themsg = 'Sorry, that name was not found.';
		return;
	}

	foreach( $result as $the_user ) {
		$wpmem_themsg = ( $fields['pin'] != $the_user['pin'] ) ? 'Incorrect PIN!' : '';
	}

	return;

Save that in a plain text file called something like pin.php

You will need to create the mu-plugins folder (e.g. by using FTP). Again, just put it where krumch said.

Then just upload the pin.php file to the mu-plugins folder.

Thanks KTS915. I created the php just as you mentioned above as well as the mu-plugins folder then added the php to the folder. I then registered with incorrect information to see if the registration would be denied and unfortunately the registration went through. So this did not work ??

Then it appears either that you will need to modify the code or that you will need a different hook from user_register

You could start by experimenting by using a different hook. The full list of registration-related hooks is here.

I’ve tried several of the hooks. Nothing has worked yet, I’m probably not doing this right. Thanks again KTS915.

My fault: the hook I show fires after the user is created. You must fine some, that fires before the creation of the new user. Maybe “init”. Maybe inside s2M…
