How to prevent form from sending mail after antispam validation

Hello, I use this spam-blocker validation:

​
It works fine, but after validation the form nonetheless is sending the message.
​
I would really appreciate your help.
Best, Jens

Hi Jens,
​
The Event Switcher action needs to be before the Email action for this to work.

Hello Bob,
many thanks for your quick response. You are right, that's it.
I know, if this is not a PHP lesson, but concerning this line:
$result = $filter->check_text($form->data['questions']);
Is it possible to validate more than one field?
​
Sorry for that.
Best, Jens

Hi Jens,
​
You can add an array of input names and then loop through that array at the $results line:

. . .
$check_these = array ( 'name', 'email', . . .);
foreach ( $check_these as $v ) {
  if ( $result ) {
    // Result contains the matched word (not the matched regular expression)
    echo "<p>There is a special place in hell reserved for people who post about '{$result}' on my form!</p>";
    return 'spam';
  }
}
. . .

You can change the if part to do whatever you need to happen when spam is found.
