Hi Guys:
Im currently seeing the following warning messages when I enter on of the form submission entries:
Warning: nl2br() expects parameter 1 to be string, array given in /home/botanica/public_html/officechristmastrees.co.uk/wp-content/plugins/gravityforms/common.php on line 3770
Do you think you know what this is and how i could get rid of it?
Thank you for reporting this. However, it's a warning, not an error. Do you have WP_DEBUG turned on? You should not normally be outputting PHP warnings to the screen in a production environment.
Just because it's a warning, does not mean it does not need to be resolved. This causes many issues when trying to develop 3rd party add-ons. The issue, at least for me, is that when using a Hidden Product field, the value is an array. In GFCommon:get_lead_field_display there is no case statement for the hiddenproduct field, and it uses the default case, which is to send the value to nl2br. Hidden's product is an array, not a string, so this is a BUG in gravity forms, not an warning that should be ignored.
Please just have the devs add a check before calling nl2br to determine if the value they are sending to the function is a valid value.
