Thanks for the info. </p> https://legacy.forums.gravityhelp.com/topic/getting-nl2br-warning-when-submitting-form#post-49685 Fri, 17 Feb 2012 09:40:54 +0000 Lucas Stark 49685@https://legacy.forums.gravityhelp.com/ <p>I've posted this a couple of times, however, there are times when an Array is passed to nl2br. This is the case in GFCommon::get_lead_field_display. </p> <p>There is no case branch for every field. Add a hidden product field to your form to see this in action. Since there is no branch for hiddenproduct, but the hiddenproduct value is an Array not a string, it'll generate warnings. </p> <p>Since there are many calls to nl2br, I would recommend refactoring into a GFCommon::nl2br function where you can then check the value before passing an invalid value to the PHP nl2br function. </p> https://legacy.forums.gravityhelp.com/topic/getting-nl2br-warning-when-submitting-form#post-49629 Thu, 16 Feb 2012 16:24:55 +0000 Dana Cobb 49629@https://legacy.forums.gravityhelp.com/ <p>Hi, pidesign,</p> <p>I have seen this before but cannot reproduce the issue right now. Can you send me an export of your form with all its fields so I can reproduce the issue? You can email the form export file to me at "dana@rocketgenius.com". Please reference this post.</p> <p>Thanks. </p> https://legacy.forums.gravityhelp.com/topic/getting-nl2br-warning-when-submitting-form#post-49405 Tue, 14 Feb 2012 12:59:38 +0000 pidesign 49405@https://legacy.forums.gravityhelp.com/ <p>I'm using the Directory addon with Gravity Forms and receive this warning message on the page after hitting submit:</p> <p>Warning: nl2br() expects parameter 1 to be string, array given in /home/pidesign/www/www/clients/sailpdx/wp-content/plugins/gravityforms/common.php on line 3796</p> <p>I get this warning 16 times.
