Incorrect INTEGER value associated with MySQLi Delete Record.

Imagine a webshop!
The user can add items to his basket.
Once the user has done this, they can choose to rate the product and write a review about it.

I'm working on a page that does not work as I intended. The user must be able to delete the product from the basket. And at the same time as the product is deleted from the basket, any ratings and reviews given by the user to the product must also be deleted.

There are three tables.
1. Basket
2. Reviews
3. Rating

On the page that does not work, there are:
Three “recordsets”.
Three "hidden input fields" that are linked to the respective table id.
Three "delete records", where "lookup value" is linked to the respective "hidden input field".

The idea is that the page should first see if there is a review of the current product that the current user has written. If this is true, it must be deleted.

The next step is to see if there is a rating linked. If so, this must be deleted.

Finally, the product must be deleted from the user's basket.

Am I thinking right here? Because this does not work!

If I comment out the first two "delete record" functions and only keep the one that is to delete the product from the basket - then this product is deleted as intended (but of course not the rating and review).

But if I do not comment out these two "delete record" functions, I get "incorrect INTEGER value:". And it does not say what it is?

Your $rsDeleteStory and $rsDeleteImage recordsets probably aren't returning results, and that causes the hidden form elements you are using for the delete to not have a result. Have you viewed source on your page to see if the hidden form elements you are using to record those values have a result? You could avoid that error by updating the trigger to only try to delete if there is a value:

So instead of:

php:
<?php

if (isset($_POST["Delete"]) || isset($_POST["Delete_x"])) {
  
$DeleteQuery = new WA_MySQLi_Query($bucketlistDB);
  
$DeleteQuery->Action "delete";
  
$DeleteQuery->Table "bucStories";
  
$DeleteQuery->addFilter("sto_id""=""i""".((isset($_POST["WADADeleteStoryID"]))?$_POST["WADADeleteStoryID"]:"")  ."");
  
$DeleteQuery->execute();
  
$DeleteGoTo "";
  if (
function_exists("rel2abs")) $DeleteGoTo $DeleteGoTo?rel2abs($DeleteGoTo,dirname(__FILE__)):"";
  
$DeleteQuery->redirect($DeleteGoTo);
}
?>



you can use:

php:
<?php

if (isset($_POST["Delete"]) && !empty($_POST["WADADeleteStoryID"])) {
  
$DeleteQuery = new WA_MySQLi_Query($bucketlistDB);
  
$DeleteQuery->Action "delete";
  
$DeleteQuery->Table "bucStories";
  
$DeleteQuery->addFilter("sto_id""=""i""".((isset($_POST["WADADeleteStoryID"]))?$_POST["WADADeleteStoryID"]:"")  ."");
  
$DeleteQuery->execute();
  
$DeleteGoTo "";
  if (
function_exists("rel2abs")) $DeleteGoTo $DeleteGoTo?rel2abs($DeleteGoTo,dirname(__FILE__)):"";
  
$DeleteQuery->redirect($DeleteGoTo);
}
?>



Then if there is a result it will try to delete and it will skip those if there is nothing to delete.

Thanks Ray, now I understand. I thought the server would skip this if it turned out that there was nothing in the database, but it was not that simple. I suspect that you could make a rule for this to the "trigger", but it is easier to code if you know what to do.

There are a lot of different ways you can account for it. This is just one. The trigger, in the parameter, in the hidden field... It just needs to be accounted for somewhere.
