The PHP Code


if (isset($_POST["PID"]) && isset($_POST["Name"]) && isset($_POST["Picture"]) && isset($_POST["Price"]) && isset($_POST["Type"]) && isset($_POST["Stock"])){

print("<p>could not execute query</p>");

And when i try to post
ii get the error
Warning: var_dump() expects at least 1 parameter, 0 given in C:\xampp\htdocs\web\pages\Admin.php on line 294
could not execute query

You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '0' at line 1


You are concatenating the query using plus(+) In PHP Strings are concatenating using dot(.) Also either remove the var_dump() or add any parameter to it.

$query="INSERT INTO `product` (`PID`, `Name`, `Picture`, `Price`, `Type`, `Stock`)" . "VALUES ('$PID', '$Name', '$Picture','$Price', '$Type', '$Stock')";
