After clicking button submit, only select option of “type” is posted in the database, but select option of “Supplier” did not posted and only shows “0” values in phpMyAdmin.
Whenever I try to add a product, all the details are inputted to the database, but only “supplier” field is input with “0” Example of image is as below
Example of output: https://i.imgur.com/mKyZyLj.jpg
Below is my products.php

Answer
This
$stmt->bindParam(':supplier', $supplier, PDO::PARAM_INT);
an integer parameter binding, is not compatible with
<option value="My Pets Library"
which is of course a string
Additional note:
You dont have to do
$stmt->bindParam(':pid', $pid, PDO::PARAM_STR);
// and then
$pid = $_POST['pid'];
// you can just do
$stmt->bindParam(':pid', $_POST['pid'], PDO::PARAM_STR);
Saves a bit of memory and a few CPU cycles
