I am making the magento ecommerce website. I want to make the zipcode text field on product page required (compulsory to proceed the next page) before users add the products in shopping cart. I want to make compulsory for every users to check the zipcode for their area before adding the products in the shopping cart.

This is my cod.phtml code:

 * @company     NetAttingo Technologies
 * @package     Netgo_Cod
 * @author      NetGo
 * @dev         [email protected]

$msgData = Mage::helper('netgo_cod')->getConfigData(); 
if($msgData['zip_status'] == 1){
<div class="input-box">
    <div class="z-btn">
        <label>Zip Code : </label><input type="text" placeholder="Enter your pincode" value="" name="cod" class="product-custom-option" id="cod" size="29" style='color:black; font-size:12px' required>
        <button type="button" onclick="checkCOD();" name="zip-check" title="Check" class="button" id="zip-check"><span><span>Check</span></span></button>
    <div id="cod_msg"></div>

    function checkCOD(){
        var cod = $('cod').value;
        if(cod == ''){
            $('cod_msg').update('<span class="cod-error"><?php echo $msgData['emp_msg']; ?></span>');
            $('cod_msg').update('<img src="<?php echo Mage::getBaseUrl( Mage_Core_Model_Store::URL_TYPE_WEB, true ).'media/cod/img/ajax-loader-2.gif';?>">'); 
            new Ajax.Request('<?php echo Mage::getBaseUrl().'netgo/cod/check';?>', {
                parameters: {zipcode: cod}, 
                onSuccess: function(transport) {
                    var response = transport.responseText || "no response text";
                onFailure: function() { alert('Something went wrong...'); }
<?php } ?>
