cara memperbaiki kode Notice: Undefined variable: filter_name di opencart

by

Baru coba upload theme di Opencart dan terdapat error :
Notice: Undefined variable: filter_name in C:\xampp\htdocs\webku\catalog\view\theme\beautyshop\template\common\ header.tpl on line 447



Itu karena pake themes versi 1.5.4.1 sedangkan OC-nya pake versi 1.5.5.1


Cari tulisan ini di header.tpl:

Code:
            <?php if ($filter_name) { ?>

            <input type="text" name="filter_name" value="<?php echo $filter_name; ?>" />

            <?php } else { ?>

            <input type="text" name="filter_name" value="<?php echo $text_search; ?>">                             

            <?php } ?>



Replace dg:

Code:
     <input type="text" name="search" placeholder="<?php echo $text_search; ?>" value="<?php echo $search; ?>" />
