   Pleas explain how I would limit the number of characters allowed in a field. I need to limit certain fields to say 6 or 8 numbers.

   Thanks.

   Hi,

   To set the limit you need to edit "includes/view-functions.php", for example you want to limit "Text Field" with element id = 1 in form 1, then go around line 40 ~ 50, you will see this code :

   $element_markup = <<<EOT
   		<li id="li_{$element->id}" {$error_class}>
   		<label class="description" for="element_{$element->id}">{$element->title} {$span_required}</label>
   		<div>
   			<input id="element_{$element->id}" name="element_{$element->id}"
   class="element text {$element->size}" type="text"
    value="{$element->default_value}" />
   		</div>{$guidelines} {$error_message}
   		</li>
   EOT;

   replace the code with this one

   if ($_GET['id'] == 1 && $element->id == 1)
   			$set_max = 'maxlength="8"';
   		else
   			$set_max = '';
   
   $element_markup = <<<EOT
   		<li id="li_{$element->id}" {$error_class}>
   		<label class="description"
   for="element_{$element->id}">{$element->title} {$span_required}</label>
   		<div>
   			<input {$set_max}  id="element_{$element->id}" name="element_{$element->id}"
   class="element text {$element->size}" type="text"
    value="{$element->default_value}" />
   		</div>{$guidelines} {$error_message}
   		</li>
   EOT;

   those code will limit text field size to 8

   Hi,

   I've used the above code to set the character limit to 50 for a text area but it still allows the input of more 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?

   Many thanks

   Hi,

   Have you change the form id and element id with yours in these code ?

   if ($_GET['id'] == 1 && $element->id == 1)
   			$set_max = 'maxlength="8"';
   		else
   			$set_max = '';

   Anyway if you need to apply the code in all text field on form 2 for example, you can change those condition to be like this :

   if ($_GET['id'] == 2)
   			$set_max = 'maxlength="8"';
   		else
   			$set_max = '';

   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.

   Thank you!!

   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 :

   $rules[$element_name]['max'] 		= 255;

   put these code exactly bellow that line

   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;
   
   }

   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"

   @session_start();
   $_SESSION['sess_form_id'] = 12;

   then change my previous code from :

   if ($_GET['id'] == 2)
   	$set_max = 'maxlength="8"';
   else
   	$set_max = '';

   to

   if ($_SESSION['sess_form_id'] == 2)
   	$set_max = 'maxlength="8"';
   else
   	$set_max = '';

   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?

   How do I do this for multiple fields, but not all of the same type? For example, I have some number fields that I want to restrict to 2 numbers, others I want to restrict to 3.
