Magento在产品详细信息页面加载中运行自定义脚本

Question

I'm pretty new to Magento custom modules and just want to be pointed in the right direction to read up on things.

I'm creating a few websites that I want to have stock dynamically updated from an API (that I'm developing).

Currently I have a script that runs every day to update every product with the current stock count, and another script that gets the difference since the last update and does it (every 10minutes).

I don't like it as there is still room for error and it just doesn't sit right with me. What I would like is as you click on the product, it makes an API call, updates my custom field, and renders the page. I also have a custom stock status plugin so I really need it to do the call before page load. . I can write some logic on timeout to render the page anyway if there is a problem with the API.

Any pointers would be really helpful.

Answer 1

You can use the Event/Observer feature to call the API. Try one of the following events:-

catalog_controller_product_init_before
catalog_controller_product_init_after
catalog_controller_product_view

Got it working... Thanks for your help, there is still some work to do, but its calling the script at the correct time! Thankyou

<?php

    public function execute(EventObserver $observer)
