Opencart - How I can execute a custom code on product page? Without mods on controller product

问题

I'm working on a custom module and I need to populate a table when the customer opens the product page. It was better if I don't have to mod the controller or make a custom AJAX call on view. It's possible?

Sorry by the english.

回答1:

Yes you can do this without touching the MVC pattern; although it is better and recommend to stay within the MVC methodology (quick hacks are sometimes better solutions though)

---

1 - Open \catalog\view\theme\default\template\product.tpl

2 - Find <?php echo $footer; ?>

3 - Before that place your code; by Default jQuery is already called in header.tpl

Example code: (you can easily have your table to slideDown etc.

<script type="text/javascript">
/**
* jQUERY
**/
$(document).ready(function(){
    //////////////////
    //####  SHOW CART ON CLICK
    //////////////////
    $('.cart-expand').click(function() {
            $('#cart-hidden').slideDown();
    });
    //////////////////
    //####  EXPORT AN AJAX PHP BUILD FROM MVC
    //////////////////
    <?
    $AddressofCustomerId=$this->customer->getAddressId();
    CurrentCustomerZone($AddressofCustomerId);
    ?>
});
/**
* JAVASCRIPT
**/
alert('Normal JavaScript free from jQuery');
</script>

You can even have Normal PHP within the .tpl file and call database functions within the tpl although not recommended.
