PHP - Process Form Submission with 2 Arrays-CodePudding

I have a web form that allows users to enter details for creating a shipping consignment for 1 more more items. They enter the address from/to fields and then there's a section where they can enter 1 or more rows for items to be included on the shipment.

When the user submits the form I get the following Array:

(
[action] => createConsignment
[type] => Outgoing Domestic Shipment
[parcelID] => Array
    (
        [0] => DS851234
        [1] => SM897452
    )



[productID] => Array
    (
        [0] => XT71121
        [1] => PL12134
    )
[ref] => 3902381720
)

which I then process to create records in a backend database like this:

foreach($_POST["productID"] as $productID) {
    
    $request->setField('productID', $productID);
}

This is working well but I now need to also include the parcelID when creating the new row in the backend database. So as well as getting the productID I need to get the parcelID with the same array position, so in the above example I would create a new row in the database with these pairs of values:

DS851234 and XT71121
SM897452 and PL12134

I can't work out how to reference both of these in the same foreach loop to get the values for the same array position at the same time.

CodePudding user response：

You can use the array key as follows:

foreach($_POST['productID'] as $key => $productID) {
    // ... do something with $productID
    // ... use the matching parcelID as $_POST['parcelID'][$key]

This relies on the inputs in the form appearing in the same order, obviously, so the keys of each array match up.
