Since the php explode function is supposed to be on strings, not arrays, there may be something unique about applying it to the list field. Thank you for posting your findings. </p> RoseDesign on "Prepopulating multicolumn list field results in php error, but field is populate" https://legacy.forums.gravityhelp.com/topic/prepopulating-multicolumn-list-field-results-in-php-error-but-field-is-populate#post-99787 Thu, 06 Dec 2012 19:34:25 +0000 RoseDesign 99787@https://legacy.forums.gravityhelp.com/ <p>Hi,</p> <p>I'm using gravityforms version 1.6.10.</p> <p>I'm prepopulating a list field per the example at the bottom of this page: <a href="http://gravityhelp.com/documentation/page/Gform_field_value_$parameter_name" rel="nofollow">http://gravityhelp.com/documentation/page/Gform_field_value_$parameter_name</a></p> <p>The field is populated properly, but I'm seeing the error "Warning: explode() expects parameter 2 to be string, array given in [...] form_display.php on line 1671."</p> <p>If I pass a string instead of an array, there is no error, but the field is not populated correctly.</p> <p>If I comment out line 1671 of form_display.php, all is well: no error, field populates properly.</p> <p>I don't have that list field set to use conditional logic (line 1671 is inside the <code>get_conditional_logic</code> function).</p> <p>I thought maybe one of my array values might have been causing the problem, but passing an empty array (or the array example on the page referenced above) has the same results: php error, but field is populated as expected.</p> <p>Any ideas?</p> <p>Thanks!<br /> Teresa (and Peter and Richard) </p>
