Since the above code would work for that field type only. Using "Number" field won't work. The modification should affect all existing forms.

I tried testing your method by swapping out the lines 40-47 with the exact code you suggested (I realize this would limit it to 10, not 110; this is just for testing purposes): <pre><code>$set_max = 'maxlength="10"'; $element_markup = <<<EOT <li id="li_{$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;</code></pre> ...with absolutely no effect whatsoever. Does this only impact forms or fields created *after* the code change, or should it impact existing forms/text boxes as well? microvb on "Limit number of chars per field" https://www.machform.com/forums/topic/limit-number-of-chars-per-field#post-4001 Sat, 13 Dec 2008 07:13:02 +0000 microvb 4001@https://www.machform.com/forums/ Can you not just add something to the $element function. Aka: $element->max_size; ' Define the maximum amount of characters allowed for input $element->min_size; ' Used in validation to ensure the amount of characters is of the min size or greater This would be a simple method for accepting variable size input fields with certain size requirements. If the developers of MachForm added this functionality to their "TextField" and "NumberField" data types, this should resolve this problem nicely, also providing a way for people to easily modify the character restrictions. Speaking of that, if the developers of MachForm could also add a "Store as String" option to the "NumberField" data type, this would eliminate the problems in receiving values such as 1.26473828998432874+E15 when in fact it was supposed to be a really long number. Problem with using the "TextField" data type for input of long numbers is that it does not allow for restricting that field to ONLY accept numbers. redityo on "Limit number of chars per field" https://www.machform.com/forums/topic/limit-number-of-chars-per-field#post-3894 Wed, 03 Dec 2008 17:40:50 +0000 redityo 3894@https://www.machform.com/forums/ Hi Kmnet, I've got your mail, let's continue there kmnet on "Limit number of chars per field" https://www.machform.com/forums/topic/limit-number-of-chars-per-field#post-3888 Wed, 03 Dec 2008 14:39:17 +0000 kmnet 3888@https://www.machform.com/forums/ Hi. I just bought this software. I have a problem getting the text limit based on the above instructions to work. Can you further elaborate the steps? I need single line text field to have a maximum characters of only 30. Extremely crucial to my business. Thank you. yuniar on "Limit number of chars per field" https://www.machform.com/forums/topic/limit-number-of-chars-per-field#post-3570 Thu, 06 Nov 2008 20:37:16 +0000 yuniar 3570@https://www.machform.com/forums/ Sorry wftsl, I'm afraid that won't be possible. Thank you for your suggestion though. wftsl on "Limit number of chars per field" https://www.machform.com/forums/topic/limit-number-of-chars-per-field#post-3568 Thu, 06 Nov 2008 18:52:31 +0000 wftsl 3568@https://www.machform.com/forums/ Hi and thanks for your reply. Can't this be done directly from the form properties with a hack or update of the software? There are some forms I need to limit addresses, others I need to limit names, or text boxes, and this seems to be more complicated that what I expected. redityo on "Limit number of chars per field" https://www.machform.com/forums/topic/limit-number-of-chars-per-field#post-3567 Thu, 06 Nov 2008 18:42:47 +0000 redityo 3567@https://www.machform.com/forums/ Hi, May I know, what element do you want to limit ? if it's all of element, I'm afraid you should do a lot of modification. I have an example, in here you want to limit a "text element" in form 1 on element_1. To do that, you have to edit "includes/view-functions.php", try to search between line 40 ~ 47 you will find this code : <pre><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} {$error_message} </li> EOT;</code></pre> after that replace with this one <pre><code>if ($_GET['id'] == 1 && $element->id == 1) $set_max = 'maxlength="10"'; 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} {$error_message} </li> EOT;</code></pre> if you want to have all "text element" limited, so you can ignore the "if" condition. It will be like this <pre><code>$set_max = 'maxlength="10"'; $element_markup = <<<EOT <li id="li_{$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;</code></pre> wftsl on "Limit number of chars per field" https://www.machform.com/forums/topic/limit-number-of-chars-per-field#post-3566 Thu, 06 Nov 2008 17:18:55 +0000 wftsl 3566@https://www.machform.com/forums/ Thanks webcommerce, I'd like to know if there is any "out of the box" solution for this problem, as I guess speaking of forms, this is very mandatory.

It would be useful for zip/postcode fields etc. You might also check out <a href="http://www.dynamicdrive.com/dynamicindex16/" rel="nofollow">http://www.dynamicdrive.com/dynamicindex16/</a> (Form Effects) which has some field limiting scripts. I haven't used any of these but I can say most of their scripts are pretty good (reliable).
