Hi everybody,

I am Richard, and i am a biginner in the PHP MYSQL codification. I'm developping a online site, and i am facing to a blocking point, regarding the insertion of products onsite.

I have 2 tables:

- 1 for User Registration (containning the primary key: userID)

- 1 for Products registration (containning the foreign key: userID).

This is a part of my product insertion request: "INSERT INTO shopping.produits (userID, productID, product_picture, product_name, product_desc, product_price) VALUES ($dataID, NULL, $product_picture, $product_name, $product_desc, $product_price)"

If i replace variables ($product_picture, $product_name, $product_desc, $product_price) in VALUES attribut, by putting '', and execute the request, everything works well, but, when i put variables, and execute the request, this is the message i get:

" Fatal error: Uncaught PDOException: SQLSTATE[HY093]: Invalid parameter number: number of bound variables does not match number of tokens in C:\xampp\htdocs\04 - Shopping\PHP\addProduct.php:67 Stack trace: #0 C:\xampp\htdocs\04 - Shopping\PHP\addProduct.php(67): PDOStatement->execute(Array) #1 {main} thrown in C:\xampp\htdocs\04 - Shopping\PHP\addProduct.php on line 67 "

Line 67 concerns the array.

Could you please help me?

Thant you in advance.

Regards,

Richard

What I have tried:

$req_insert_product = $bdd->prepare("SELECT *
                           FROM produits
                           INNER JOIN form1
                           ON produits.userID=form1.userID");
                           $req_insert_product->execute();
                           $all_datas = $req_insert_product->fetch();
                           $dataID = $all_datas['userID'];


                           $req_insert_products = $bdd->prepare("INSERT INTO shopping.produits (userID, productID, product_picture, product_name, product_desc, product_price) VALUES ($dataID, NULL, $product_picture, $product_name, $product_desc, $product_price)");
                           $req_insert_products->execute(array(
                               'userID' => $dataID,
                               'productID' => NULL,
                               'product_picture' => $product_picture,
                               'product_name' => $product_name,
                               'product_desc' => $product_desc,
                               'product_price' => $product_price
                           ));

The issue here is that you're mixing string variable interpolation with named parameters. In PDO statements you don't declare named parameters as $variable but instead as :variable. PHP: PDOStatement::execute - Manual[^]

You need to both change the named parameters to use a colon (:) and also make sure that the values you're passing into the execute() function also match the same names. In your code you're trying to use $dataID but you're passing in a value of 'userID', so these don't match. Below is the correct usage:

PHP
$req_insert_products = $bdd->prepare("INSERT INTO shopping.produits (userID, productID, product_picture, product_name, product_desc, product_price) VALUES (:userID, NULL, :product_picture, :product_name, :product_desc, :product_price)");

$req_insert_products->execute(array(
        'userID' => $dataID,
        'product_picture' => $product_picture,
        'product_name' => $product_name,
        'product_desc' => $product_desc,
        'product_price' => $product_price
));

Also note that I removed the 'productID' => NULL as this isn't actually being used in the query.

$bdd is my data base connexion request.
Thank you for your help, this is what i did, and it works:


$req_getID = $bdd->prepare("SELECT *
                            FROM produits 
                            INNER JOIN form1 
                            ON produits.userID=form1.userID");
                            $req_getID->execute();
                            $all_datas = $req_getID->fetch();
                            $dataID = $all_datas['userID'];
                            

                            $req_insert_product = $bdd->prepare("INSERT INTO shopping.produits (userID, productID, product_category, product_picture, product_name, product_desc, product_price) VALUES (:dataID, :productID, :product_category, :product_picture, :product_name, :product_desc, :product_price)");
                            $req_insert_product->bindValue(':dataID', $dataID, PDO::PARAM_INT);
                            $req_insert_product->bindValue(':productID', NULL, PDO::PARAM_NULL);
                            $req_insert_product->bindValue(':product_category', $product_category, PDO::PARAM_STR);
                            $req_insert_product->bindValue(':product_picture', $product_picture, PDO::PARAM_INT);
                            $req_insert_product->bindValue(':product_name', $product_name, PDO::PARAM_STR);
                            $req_insert_product->bindValue(':product_desc', $product_desc, PDO::PARAM_STR_CHAR);
                            $req_insert_product->bindValue(':product_price', $product_price, PDO::PARAM_INT);
                            $req_insert_product->execute();
