Is this a multi-page or a single-page form? If it is a multi-page form, it would be helpful if you exported the form (Forms-&gt;Import/Export-&gt;Export form) and pasted a link to the exported XML file. </p> https://legacy.forums.gravityhelp.com/topic/bug-gform_pre_render-isrequired-does-not-work-for-fileupload-fields#post-38814 Mon, 24 Oct 2011 19:46:31 +0000 dotcom 38814@https://legacy.forums.gravityhelp.com/ <p>Thank you Alex for the superb reply.</p> <p>We're using v1.5.2.8 - as we have done extensive customisations the upgrade is in the pipeline but not possible at the minute.</p> <p>Have attempted to write the function using Gform_validation but really struggling: <a href="http://www.pastie.org/private/lfr5pyunl9acted3bpocw" rel="nofollow">http://www.pastie.org/private/lfr5pyunl9acted3bpocw</a></p> <p>Could you help me out with this? </p> https://legacy.forums.gravityhelp.com/topic/bug-gform_pre_render-isrequired-does-not-work-for-fileupload-fields#post-38750 Mon, 24 Oct 2011 12:08:25 +0000 Alex Cancado 38750@https://legacy.forums.gravityhelp.com/ <p>The problem is that the gform_pre_render fires after the form validation takes place, so you can't use it to change the validation behavior. I wouldn't call it a bug, but I do agree that not being able to mark a field as required in that filter is counter-intuitive. I will be looking at ways to improve this.<br /> For now, you can use a combination of the gform_pre_render filter and the gform_field_validation filter to accomplish what you need. Following is a code snippet.<br /> <a href="http://pastie.org/2751185" rel="nofollow">http://pastie.org/2751185</a></p> <p>Note that gform_field_validation is new in 1.6. If you are not using that version and do not want to upgrade, you will need to use the gform_validation filter. Following is it's documentation.<br /> <a href="http://www.gravityhelp.com/documentation/page/Gform_validation" rel="nofollow">http://www.gravityhelp.com/documentation/page/Gform_validation</a> </p> https://legacy.forums.gravityhelp.com/topic/bug-gform_pre_render-isrequired-does-not-work-for-fileupload-fields#post-38730 Mon, 24 Oct 2011 11:16:55 +0000 Chris Hajer 38730@https://legacy.forums.gravityhelp.com/ <p>Which version of the plugin are you using? </p> https://legacy.forums.gravityhelp.com/topic/bug-gform_pre_render-isrequired-does-not-work-for-fileupload-fields#post-38686 Sun, 23 Oct 2011 13:30:09 +0000 dotcom 38686@https://legacy.forums.gravityhelp.com/ <p>Gravity forms is unable to modify the required status of a fileupload field.</p> <p>Test A:<br /> All fileupload fields were set to required in the form editor.
