I'm using the Directory addon with Gravity Forms and receive this warning message on the page after hitting submit:
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
I get this warning 16 times. The data is successfully recorded though.
Any ideas?
Hi, pidesign,
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.
Thanks.
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.
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.
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.
Hi, oceancountycoll,
I knew an array was being passed, just didn't know which field combination was causing the issue so I could reproduce it. Thanks for the info.
