change the length of the product name in Admin

Problem: product names can be up to 128 characters in length in the database (products_description table: products_name)

However the default limit on the number of characters displayed in the Categories & Products area in the Admin is only 64. If you have product titles that are longer than this, you need to change this default.

File: admin/categories.php

Line 1880
<td class="main"><?php echo tep_draw_input_field('products_name
[' . $languages[$i]['id'] . ']', $products_name_field, 'size="64"
maxlength="XXX"'); ?></td>

Change the ‘xxx’ value to any number of characters up to 129.
