Input on Single Line Text is cut off after

Would it have to do with this chunk of code from gravityforms.js? Does < need to be added into the criteria somewhere?

this.htmlDecode = function(text) {
        var c,m,d = text;

        // look for numerical entities "
        var arr=d.match(/&#[0-9]{1,5};/g);

        // if no matches found in string then skip
        if(arr!=null){
            for(var x=0;x<arr.length;x++){
                m = arr[x];
                c = m.substring(2,m.length-1); //get numeric part which is refernce to unicode character
                // if its a valid number we can decode
                if(c >= -32768 && c <= 65535){
                    // decode every single match within string
                    d = d.replace(m, String.fromCharCode(c));
                }else{
                    d = d.replace(m, ""); //invalid so replace with nada
                }
            }
        }

Thanks. Tried one small thing, but hardly worth mentioning.

Thanks, Carl. I see that 1.6 was released for the Wordpress plugin. I upgraded through there.

This may be a bit of a n00b question, but how do I apply a hook?

Thanks, guys, but that didn't quite do it.

Now when I input "21782<wjk&*>/dwd",
it returns "21782/dwd"

and when I input "21782<wjk&9jjijk",
it returns "21782"

I'm thinking that I must be applying the filter incorrectly.

I did some further testing and it always worked like this…

when I input "21782<wjk&*>/dwd",
it returns "21782/dwd"

and when I input "21782<wjk&9jjijk",
it returns "21782"

So the first filter didn't seem to affect anything either–therefore, I'm probably applying the filter incorrectly.

The functions.php file that I'm pasting the code into is root/wp-content/themes/current_theme/functions.php. The only thing that I've been removing is the top <?php b/c dreamweaver shows a syntax error.

The code for the functions.php file is here http://pastebin.com/bMx9g7rs

Thanks again for your help. I appreciate it.

Good catch! I missed that part.

I'm close!
It's converting to hexadecimal, but not converting back.

	else {

add_filter('gform_entries_field_value', 'ch_hextostr_list', 10, 3);
function ch_hextostr_list($x, $form_id, $field_id) {
	// run this code on form 7, field 5 only
	// change to match your form values
	if ($form_id == 7 && $field_id == 5) {
		$s='';
		foreach(explode("\n",trim(chunk_split($x,2))) as $h) {
			$s .= chr(hexdec($h));

}

If it's going to be time consuming/difficult, we can work with this as is. The application that will read the email can be written to convert the hex back.

Thanks again, guys. Chris, especially, you are a form superhero.

No worries. Sorry for missing that originally.

This will work fine. Thank you so very much! I really appreciate your hard work.
