Change quantity PHP

kg567

Can I please have an example of how to change the quantity of an item (SLIP) in the Session?  I am using the PHP SDK and do not understand how to send the alter array as the API documentation describes.  Thanks!

Hi kg567,

Thanks for reaching out!

Here's an example of how you could modify the quantity (parameter ID) of an item using the PHP SDK.

$qty = 5;
$data = [   
   'date' => $date,
   'item_id' => $item_to_book,
   'param' => [
      'qty' => $qty
   ]
];
$response = $this->checkfront->get('item', $data );

Hopefully this helps. Please let us know if you have any other questions.

Cheers,

I am trying the following code to no luck...can you please let me know where the error is occuring?

$url = "session_id=$sessionid&alter[$line_id]=$qty";
$Booking->set('booking/session/', $url);

On the API docs it says to use the alter array.  Am I not doing this correctly?  I am trying to change the quantity of an item that has already been added to the session.

Hi kg567,

If I were to set the booking session I'd do something like this:

public function session( $slip ) {
    $data = [
        'slip' => $slip
    ];
    
    $session = $this->checkfront->post('booking/session', $data );
    
    return $session['booking']['session']['id'];
}

Hopefully this helps!

I have already set the slip in the session.  Is there a way to just change the quantity that the slip contains without sending another slip?

@Mitch I'm experiencing the same issue with setting item quantity. Can you please provide php example to set quatity.

That is how I try it now.

$slip = $response['item']['rate']['slip'];
if($slip){
   $response = $checkfront->post('booking/session', [
      'slip'  => [$slip]
   ]);
   $session  = $response['booking']['session']['id'];
   if($session){
      $checkfront->set_session($session,$response['booking']['session']);
      $response = $checkfront->post('booking/session', [
         'alter'      => [
            1 => 3
         ]
      ]);

Obviously 1 is index of item added in first session call. Tried adding session_id as parameter to second post request, but had no luck.

"item": {
                "1": {
                    "sku": "verzendingenterugsturenviagls",
                    "item_id": 62,
                    "slip": "62.20190313X6-aantallevering.1",
                    "available": 1000000000
                }
            }

There is reference to some line_id parameter in docs, but I don't see it in response.

I found old post about items with simple pricing are allowed to set quantity, but can't find where can I check if item is simple pricing or not in UI or API.
