    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 = '';
