I would like to know how I can do to insert data into two tables at the same time, well I do not know if it's right the way I'm doing it is not giving any error but I also did not insert anything.

The code below.

<?php
error_reporting(-1);
ini_set('display_errors', 'On');

//Criar a conexao
$link = new mysqli ("localhost", "root", "", "peixaria");
if($link->connect_errno){
     echo"Nossas falhas local experiência ..";
     exit();
}

if($_SERVER['REQUEST_METHOD'] == 'POST') {
        $numero_mesa = $_POST['numero_mesa'];
    $pedido = $_POST['pedido'];
    $quantidade = $_POST['quantidade'];

    //echo "$nome_usuario - $email_usuario";

    //echo "<pre>"; print_r($_POST); exit;

    $query1 = "INSERT INTO pedido (mesa) VALUES ('$numero_mesa')";
   mysqli_query( $query1 );

    $id = mysqli_insert_id();

    $query2 = "INSERT INTO item_pedido (pedido,quantidade) VALUES ({$id}, '$pedido', '$quantidade')";
    mysqli_query( $query2 );

}

?>

You forgot to pass all required parameters to the mysqli_query function.

Change these lines:

mysqli_query( $query1 );
mysqli_query( $query2 );

To:

mysqli_query($link, $query1);
mysqli_query($link, $query2);

The problem is similar to what I answered this question. The difference is that you are not using procedural mode, but come on.

First you create the connection:

$link = new mysqli ("localhost", "root", "", "peixaria");

If the credentials are correct there is no error, so $link is who has access to the MySQLI class and has access to MySQL.

Now you need to use:

$link->funcao();

This is because it is the $link that is with the MySQLI class, so that you can use the functions, you should use:

$link->query($query1);

This applies to all functions, for example:

$link->insert_id;

Not all MySQLI functions will use $link .

I can not technically explain, but you want to get the result of one, for example use mysqli_fetch_array , you should use the variable that has the result.

For example:

$link = new mysqli ("localhost", "root", "", "teste");
$resultado = $link->query('SELECT * FROM tabela WHERE id = 1');

$resultado->fetch_row();

You should not use $link->fetch_row() , an easy way to see what you need is to see the documentation, it says exactly who should be called. ;)

I think you've been able to understand logic.
