The form isn't unusual in any way except I have added two column css classes to some fields (not the ABN one).</p> <p>I tested the field as Required - the standard "This field is required" message appears if the field is empty. But if I add less than 11 digits, or a wrong number, the same thing happens. The error message appears at the top of the page, but no error message on the field.</p> <p>I tested it without Required checked, too. No success.</p> <p>I have copied and pasted your code without editing. And applied the validate-abn css class to the field. There is no error if the number is correct, too, btw. So that is working.</p> <p>I'm stumped at what to look at next.</p> <p>The form's website is currently password protected during development. Otherwise I could post the URL here. </p> https://legacy.forums.gravityhelp.com/topic/custom-validation-help-needed#post-21820 Mon, 28 Mar 2011 15:07:26 +0000 David Smith 21820@https://legacy.forums.gravityhelp.com/ <p>Hi Cazwilson,</p> <p>Here is some updated code that addresses the multi-page and non-visible scenarios: <a href="http://pastie.org/1727617" rel="nofollow">http://pastie.org/1727617</a></p> <p>I was unable to recreate the first issue you reported. The field in error is correctly labeled in my testing of this code. I used the sample ABN number provided on the following page to test:</p> <p><a href="http://www.ato.gov.au/businesses/content.asp?doc=/content/13187.htm" rel="nofollow">http://www.ato.gov.au/businesses/content.asp?doc=/content/13187.htm</a> </p> https://legacy.forums.gravityhelp.com/topic/custom-validation-help-needed#post-21725 Mon, 28 Mar 2011 00:15:04 +0000 cazwilson 21725@https://legacy.forums.gravityhelp.com/ <p>Hi David,</p> <p>Thank you so much for your time.</p> <p>On a single page form with no conditional logic it does works in so much as displaying this message:<br /> "There was a problem with your submission. Errors have been highlighted below".<br /> But there is no field specific error message.</p> <p>Also, if the field is not visible - that is, on another page of a multi-page form, or hidden due to conditional logic, the above error message appears - because nothing has been entered in the field.</p> <p>Would it be possible to work around these issues?</p> <p>Thanks again.<br /> CW </p> https://legacy.forums.gravityhelp.com/topic/custom-validation-help-needed#post-21668 Sun, 27 Mar 2011 09:35:14 +0000 David Smith 21668@https://legacy.forums.gravityhelp.com/ <p>Hi Cazwilson,</p> <p>Paste the following code into your theme's functions.php file: <a href="http://pastie.org/1721964" rel="nofollow">http://pastie.org/1721964</a></p> <p>Instead of validating these by the field ID, I've updated the code to validate by a CSS class. Any field you'd like to validate with the ABN function, just add this to the CSS class property: "validate-abn".
