Hello, yes ! I need to get customer reviews from another table and display them on the product's miniatures on category page (stars)

[renaud2263]

My reviews are managed by a module, but yes, it's exactly what I'm searching to do...But where can I use WHERE  reviews_table.id_product=this_id_product ? I need to build a new module and hook it on "ProductReviews" ? And in this hook I must write this request ? Sorry I don't really understand...

At first you need to told the module name and their table structure name and files, then community member can give you the full sql correctly if you are not expert.

You find the table name and filed name and relation ship with theme and in your custom module you need class via PrestaShop DB class and then send the result data in 

ProductReviews hook. If you can share the module then any community member can help.

Without know no one can help as you are not expert to find where you need to put the code and how to do

 

Thank you
