Strip line-breaks during submission?

  1. Is there a way to strip line breaks from a field before I use the data submitted?

    We've got a basic form - but it has to pass alot of information as a query string, and there is a paragraph area that often people type "enter/enter" to get two line breaks. Is there a function I can use to REMOVE those during submission?

    Hi there, I don't know that you should be passing a paragraph of text through a query string as there are potential issues with that, and the string, despite reformatting won't ever get those line breaks back. You could try using the gform_pre_submission hook to strip them out using something like the script found here:

    http://php.net/manual/en/function.str-replace.php

    I think they might be hiding as /r and /r/n in the text that is submitted, but I'm not certain. Instead of replacing them with html line breaks, you would want to replace them just with a space or something.

  3. I know it's not "ideal" - but for this application it's really not an issue passing it as a query string. The only real issue is the line breaks! Thanks for the script though - I'll let you know how it turns out

  4. So do I past the code in functions.php?

    add_action("gform_pre_submission", "strip_linebreaks");
    function strip_linebreaks($form){
    	$_POST["input_11"] = preg_replace("/\r?\n/", "", ($_POST["input_11"]);
    }

    Yes, it would go in your functions.php file. And you might want to put a space in the second area for your preg_replace. Also, what is the question mark in your carriage return and new line call?
