Unable to get requested data and write onto cart table from posting form

[Joel254]

viewDetails php reads data from products table of MySQL database. Why am I not able to insert the requested data into cart table using cart.php? this question relates to php and MySQL shopping cart

 

 

viewDetails.php

cart.php

[Barand]

to see the error message you need

die('Error: ' . mysqli_error($link));

or

 die('Error: ' . $link->error);

Turning php error reporting on would alert you to that error

I tried catching the error as you said but nothing showing.

 

If I echo the SQL statement, it shows I am not getting anything from viewDetails.php apart from quantity.

 

I think the issue is do to with I have a quantity field on viewDetails.php that can be incremented after pulling data from products table, also the add button that when clicked should initiate cart.php  or it could be reading data from a table doing something on that data like incrementing a quantity and posting it
