WordPress Registration Email Validation

[jlau]

Hi there,

I’ve created a custom registration page using Registration Plus Redux and I need to create a more specific email validation. Basically I need to only allow ‘ac.uk’ email addresses to register. But I need people to be able to register with emails such as:

[email protected]

and also

[email protected]

Any help would be greatly appreciated. I have tried to use a plugin called ’email validation’ or something similar, but it hasn’t been updated in over a year and either doesn’t work or isn’t compatible with registration plus redux.

Thanks in advance

Hi jlau, I guess you are meaning “how to validate such an email address”.

Basically you may have a regular expression to do this in PHP, and maybe following code will work for you:

if(preg_match('#^[a-z0-9_.-]{1,50}@([a-z0-9_-].){0,5}ac.uk$#i',$email)){

echo "Yeah, you have an ac.uk email address!";

}

else{

echo "Oops, your email address is not valid or is not an ac.uk email address!";

}

Hi ddliu,

Thanks a lot for the reply. I really appreciate it. I’m not super comfortable with php/wordpress. So where would I put this code in my theme to get it to affect my registration?

If it helps my website is http://www.heruni.com

I don’t think it’s in the theme, you may change it here:
file wp-login.php, find function “register_new_user”, find code:

// Check the e-mail address

if ( $user_email == '' ) {

$errors->add( 'empty_email', __( 'ERROR: Please type your e-mail address.' ) );

} elseif ( ! is_email( $user_email ) ) {

$errors->add( 'invalid_email', __( 'ERROR: The email address isn’t correct.' ) );

$user_email = '';

} elseif ( email_exists( $user_email ) ) {

$errors->add( 'email_exists', __( 'ERROR: This email is already registered, please choose another one.' ) );

}

add following code at the end of the if…else… scope:

elseif (!preg_match('#[@.]ac.uk$#i', $user_email){

$errors->add( 'invalid_email', __( 'ERROR: Only "ac.uk" email address allowed.' ) );

$user_email = '';

}

Maybe there is a way to change it in the theme? I have no idea, don’t know that much.

Thanks a lot! It worked well :)

If anyone else wants to use this code. Theres a right bracket missing after $user_email.

Does anyone know how to change this from the theme?

Hi , its very easy to verify Email validation. For Email Validation you can simply go through this site http://www.melissadata.in/cloud-services/global-email-cloud-service

One link might be useful if it’s relevant enough. But three in a row without anything else and I’d say you’re a spammer.
