echo'[[!FormItRetriever]]';
$text='[[!+fi.text]]';

$textlaenge = strlen($text);

for($i=0; $i<$textlaenge; $i++) {
echo ord(substr($text,$i,1)).',';
}

I will get 91,91,33,43,102,105,46,116,101,120,116,93,93,
which is not the including... it's the Formit Placeholdername itself.
Echoing $text outputs the including... i want the including seperate.

So how do i extract it's contens(including) into another real variable like $text2?
I want to check the ASCII of every single Char in the Content. Not of the Placeholdername.

Hope i am understandable.

Thank you!!!

with best regards,

you cannot use modx-tags in a snippet.

where are you calling this code?
Is it a formit-hook-snippet or a standalone-snippet?

Think you will need a formit-hook. Check the formit-docu for infos how to create hooks.
Or tell us more details about that, what you are trying.

I have to proof the content in

 [[!+fi.text]]

of special chars. Especially Linebreaks..

BTW: I use it in a Snippet, and it shows it contents alright there... but i can't extract them. [ed. note: theoretiker last edited this post 12 years ago.]
