For example, I have some number fields that I want to restrict to 2 numbers, others I want to restrict to 3. kdy on "Limit field characters" https://www.machform.com/forums/topic/limit-field-characters#post-9084 Tue, 30 Mar 2010 18:50:34 +0000 kdy 9084@https://www.machform.com/forums/ Hi there, I am having som problems with this one. It seems that this solution is only working for "text" elements, but not "textareas"? I have a template ID 25 with element ID 9 where I need to limit characters to 160. I have tried replacing the "$element_markup" code with the one supplied by you. It works fine on element id 1 in my form, which is a text element. But when I change to element 9, which is a textarea, nothing happens? Could you please help me? redityo on "Limit field characters" https://www.machform.com/forums/topic/limit-field-characters#post-6917 Thu, 13 Aug 2009 22:46:45 +0000 redityo 6917@https://www.machform.com/forums/ I see... advance embed code have different approach indeed. I think the easy way by editing "includes/post-functions.php" file to set a maximum input validation, so when the user input exceed maximum length, it'll show the error. To do so, go to around line 165 and you will see this code : <pre><code>$rules[$element_name]['max'] = 255;</code></pre> put these code exactly bellow that line <pre><code>if ($form_id == 4 ) { if ($element_id == 9 || $element_id == 10) $rules[$element_name]['max'] = 4; elseif ($element_id == 19) $rules[$element_name]['max'] = 16; }</code></pre> Otherwise you can change my previous code, by adding a session variable in your PHP page. Add these code to your PHP page after "<?php" <pre><code>@session_start(); $_SESSION['sess_form_id'] = 12;</code></pre> then change my previous code from : <pre><code>if ($_GET['id'] == 2) $set_max = 'maxlength="8"'; else $set_max = '';</code></pre> to <pre><code>if ($_SESSION['sess_form_id'] == 2) $set_max = 'maxlength="8"'; else $set_max = '';</code></pre> nunya on "Limit field characters" https://www.machform.com/forums/topic/limit-field-characters#post-6913 Thu, 13 Aug 2009 12:42:41 +0000 nunya 6913@https://www.machform.com/forums/ Here's a question: I am integrating my form (id = 4) using the Advanced Code method (which does a php include), so the above code does not work because it is trying to $_GET the form ID and element ID from the url. My question is how can I limit the characters in a field when using the Advanced Code Form method? My form id is 4. I would like to limit element_id 9 and 10 to 4 characters and element_id 19 to 16 characters.

Also, I have a number of text areas in my form that must be limited to 50 characters. Is there a way that I could have a default set for all text areas in form_1 for instance?
