Please try with my guide:
Open mod_virtuemart_search.php file in modulesmod_virtuemart_search folder, at about line 29, find following code:
[PHP]<!–BEGIN Search Box –>
<form action=”<?php $sess->purl( $mm_action_url.”index.php?page=shop.browse” ) ?>” method=”post”>
<p><label for=”keyword”><?php echo $VM_LANG->_(‘PHPSHOP_SEARCH_LBL’) ?></label></p>
<p>
<input name=”keyword” type=”text” size=”12″ title=”<?php echo $VM_LANG->_(‘PHPSHOP_SEARCH_TITLE’) ?>” class=”inputbox” id=”keyword” />
<input class=”button” type=”submit” name=”Search” value=”<?php echo $VM_LANG->_(‘PHPSHOP_SEARCH_TITLE’) ?>” />
</p>
</form>
<!– End Search Box –> [/PHP]
and change to:
[PHP]<!–BEGIN Search Box –>
<form action=”<?php $sess->purl( $mm_action_url.”index.php?page=shop.browse” ) ?>” method=”post”>
<div class=”search<?php echo $params->get(‘moduleclass_sfx’) ?>”>
<input name=”keyword” type=”text” size=”12″ title=”<?php echo $VM_LANG->_(‘PHPSHOP_SEARCH_TITLE’) ?>” class=”inputbox” id=”keyword” />
</div>
</form>
<!– End Search Box –> [/PHP]
