PHP validation

Settings​

• Error message - The message to display next to the element if the Validation fails. This text should explain why the Validation failed and what steps the user should take to remedy the error.
• Condition - A PHP expression which if returns false, means that the Validation is not run.
• PHP -PHP code to run.
  • The element's submitted value is found in the variable $data.
    
  • Other element values can be found in $_REQUEST (use JFactory::getApplication()->input->get() to access).
    
  • If the code returns TRUE then the Validation is successful,
  • If it returns FALSE then the Validation fails.
  • You can also return a string which can be used if the 'Match or replace' option is set to 'replace'
• Match or Replace - If set to match then the Validation behaves as normal and on Validation failure returns you to the form showing the error message. If set to 'replace' then the submitted value is replaced with the data returned from the 'PHP code' script
• Tip text - additonal informational text which is displayed as a tip when the user hovers over the element's label. This can provide specific information about the Validation, enabling the user to correctly fill in the field.

Examples​

$app = JFactory::getApplication();

$f = $app->input->get('tablename___elementname', 'default value', 'string'); //'string' = filter e.g. 'INT','STRING'

$f = JFactory::getDate($f)->toUnix();

$data = JFactory::getDate($data)->toUnix();

return $data > $f;
