Php 如何在两个相互关联的表中插入数据？

在一个示例场景中，我在mysql中有两个表，即products和product_images，它们分别作为一对多关系进行关联。我想使用数据库中的一个表单插入数据，该表单将products表中的原始product_id与作为images表中外键的pro_id表关联起来，例如，product_id=1在images表中具有pro_id=1的图像。

我对这个完全陌生，请帮忙，谢谢

如果您正在使用mysqli

    $connection = mysqli_connect(your database information);

    //from the form create the main record insert statement into mysql
    mysqli_query($connection, 
    "INSERT INTO yourtable
    (fields)
    VALUES
    (values)
    ");

    //get the id of that record you just inserted
    $id = mysqli_insert_id($connection);

    // get the images from the form
    $images = $_POST['images'];
    //this is assuming your images are sent as an array of images from the form, would be slightly different if there is only one.

foreach($images as $image){
    mysqli_query($onnection,
    "INSERT INTO images_table
    (product_id, all other fields)
    VALUES
    ($id, all other values)
    "
    );
}
