I use an extra user-field for "City" in the forum registration.
I'll need a plugin that attach into the validation function, that
check that entered response is not equal to "city" or "yes".

I basically only need the declaration, and how to find the value of the field.

Thank You.

Sample custom_field_validator.plugin:


<?php
plugin_add_hook('CUSTOM_FIELD_VALIDATE', 'plugin_custom_field_validator');



function plugin_custom_field_validator($array) {

    list($field_id, $field_name, $field_value) = $array;

    return 'ERROR: '. $field_value .' for '. $field_name .' is wrong';

}



function custom_field_validator_info() {

    return array('name' => 'Custom Field Validator',

                 'desc' => 'Validate custom profile fields.',

                 'version' => '1.0');

}

?>

It seems that the caller send an extra parameter $err, and that
the error-string is truncated into one character.
The OK response is zero.

<?php
plugin_add_hook( 'CUSTOM_FIELD_VALIDATE', 'plugin_custom_field_validator');

function plugin_custom_field_validator( $array) 
{
   list( $err, $field_id, $field_name, $field_value) = $array;
   if ( $field_name == 'City')
   {
      $f_test = strtolower( trim( $field_value));
      if ( $f_test == 'city' || $f_test == 'yes')
      {
         return 'ERROR';
      }
   }
   return 0;
}

function custom_field_validator_info() 
{
    return array( 'name' => 'Custom Field Validator',
                  'desc' => 'Validate custom profile fields.',
                  'version' => '1.0');
}
?>
