How to resolve this warning which is shown when I use "custom tables" plugin for Wordpress? Can anybody help me please
Warning: Invalid argument supplied for foreach() in ..\wp-content\plugins\custom-tables\pages\show_table.php on line 378
URL of this plugin http://wordpress.org/extend/plugins/custom-tables/
The Invalid argument supplied for foreach() is obtained when the element pased in the foreach() is not an array. For this plugin, at line 378:
foreach ($qry as $row) { You can test if it is an array before passing through the foreach loop:
if ( is_array($qry )) { foreach ($qry as $row) {...} } else die('not an array'); However, I encourage you to ask from the plugin support forum. The author can fix the plugin (assuming it's a problem with the plugin itself). Modifying the core of a plugin yourself is not advisable and consequently updating that plugin will overwrite your changes.
