将数据插入多个不同的数据表

Question

I was trying to insert data into multiple data tables. It's only working for single data tables, I'm just wondering how I would be able to insert data into two data tables. I've been struggling with this issue for the past few hours and can't seem to get to the bottom of it. If anyone has any advice please let me know. :)

    <?php
/* Attempt MySQL server connection. Assuming you are running MySQL
server with default setting (user 'root' with no password) */
$link = mysqli_connect("localhost","ivodatat","","");


if($link === false){
    die("ERROR: Could not connect. " . mysqli_connect_error());
}

// Inputs for security 
$fname = mysqli_real_escape_string($link, $_REQUEST['fname']);
$sname = mysqli_real_escape_string($link, $_REQUEST['sname']);
$address = mysqli_real_escape_string($link, $_REQUEST['address']);
$email = mysqli_real_escape_string($link, $_REQUEST['email']);
$phone = mysqli_real_escape_string($link, $_REQUEST['phone']);
$mac = mysqli_real_escape_string($link, $_REQUEST['mac']);
$installer = mysqli_real_escape_string($link, $_REQUEST['installer']);
$status = mysqli_real_escape_string($link, $_REQUEST['status']);

// Insert Query 
$sql1 = "INSERT INTO leadlist (fname, sname, address, email, phone, mac, installer, status) VALUES ('$fname', '$sname', '$address', '$email', '$phone', '$mac', '$installer', '$status')";

$sql2 = "INSERT INTO $installer (fname, sname, address, email, phone, mac, installer, status) VALUES ('$fname', '$sname', '$address', '$email', '$phone', '$mac', '$installer', '$status')";



if (mysqli_multi_query($link, $sql1, $sql2)){



                mysqli_close($conn);
                header("Location: installercontrol.php");




                exit;

} else{
    echo "ERROR: Could not able to execute $sql. " . mysqli_error($link);
}

// Close The Connection
mysqli_close($link);
?>

To use mysqli_multi_query you need to append the queries to each other as it only takes one query argument. From the manual:

Executes one or multiple queries which are concatenated by a semicolon.

Try this instead:

mysqli_multi_query($link, $sql1 . ';' . $sql2)

You should probably also update your error message:

echo "ERROR: Could not able to execute $sql1;$sql2. " . mysqli_error($link);
