When adding PHP in a form rigth in the adhoc textarea, we get this help
You may specify code here, or select a PHP File, or both.If both, file will be included, then this code run.If you need to modify data submitted by the form,use $formModel->updateFormData('tablename___elementname_raw',$newvalue).Note that the '_raw' is needed!You can use {tablename___elementname} placeholders in your PHP codeIf you are inserting content around the form (e.g. getBottomContent, getEndContent, getTopContent) then do not echo out the content, instead use return, e.g.:return 'hello world';
In fact, it works without _raw as stated in php.php comment :
Code:
/**
* if you want to modify the submitted form data
* $formModel->updateFormData('tablename___elementname', $newvalue);
