For instance, a credit card number is long but does not exceed a certain length, requires to be a minimum length and should not be passed as a numeric value. It should also then be validated by LUHN 10 algorithm. Same with bank account information, etc.</p> <p>Currently, basic functions that your product doesn't support is setting of maximum and minimum field lengths. This should be available on all field types except &lt;select&gt;, and &lt;input type="checkbox"&gt;. </p> https://www.machform.com/forums/topic/new-custom-field#post-4008 Sat, 13 Dec 2008 11:04:07 +0000 yuniar 4008@https://www.machform.com/forums/ <p>Sorry, this one would require a lot of code changes among multiple files. We can't help much with it.</p> <p>We'd be glad to help with some small functionality adjustment, but new functionality or other complex customization won't be supported. </p> https://www.machform.com/forums/topic/new-custom-field#post-4002 Sat, 13 Dec 2008 07:28:26 +0000 microvb 4002@https://www.machform.com/forums/ <p>What code do I need to modify to create a new custom field with custom validation.</p> <p>Lets start with something simple:<br /> INPUT TYPE = Text<br /> MIN_SIZE = 5<br /> MAX_SIZE = 5<br /> NUMBERS ONLY<br /> VALUE IS STORED AS TYPE STRING<br /> FIELD IS REQUIRED</p> <p>(ps. I noticed a couple of other posts similar to this, however, this is a very different subject matter in the fact I am not attempting to customize the style of the field, only to create a new field type to show up on the Edit Form page) </p>
