Execute script before loading product details

[AfterGlow93]

Hello, 

I am working on my car parts retail shop.

To get prices and stock available in realtime, i built a script which process suppliers page and scrape live data from suppliers (they don't have any api or way to retrieve it by another way). Script generates a combination by suppliers with quantity and prices if it doesn't exists, else, updates existing combination with price and quantity available.

Script is working perfectly.

What i am looking to do now, is to pass product_id when product_details page is loading, and execute script for a given product_id. I already built the function using $_GET['productid']. But i can't find a hook which can be used before product is loaded.

Does the actionPresentProduct hook can do the job for it ?

Or should i override product presenter to include call of the function i need ? 

I want to avoid script to launch while browsing on product lists, i want it only on product details.

Thanks for help

Hello @AfterGlow93,

To load a script before the product details page in PrestaShop, follow these steps:

Navigate to the root directory of your project, then go to "themes/{{your_theme}}/assets/js". Place your JavaScript file in this location

Navigate to the "themes/{{your_theme}}/templates/catalog" directory and find the "product.tpl" file. Add the following code:

{if isset($page.page_name) && $page.page_name == 'product'}
    <script src="{$urls.js_url}{{your_script_name}}"></script>
{/if}

 

Make sure to replace "{{your_script_name}}" with the name of your JavaScript file.
After making these changes, you may need to clear the cache.

I hope this helps!
