Don't you have to write the appropriate query to delete from the table,

$query = "DELETE FROM $mySQL_itemTable WHERE itemsPK = '$itemPK'";

Would that do? Be careful that you don't remove the WHERE clause or it would delete everything.

Take care

Make the delete button post the form to a page that has this code for deletion. It might post to itself and you might have a form variable saying it was the delete button that was hit.

In your form, you need to fnd out what button was hit. Update or Delete. You could try this,

<input type="submit" name="submit" value="Update Item" /><input type="submit" name="submit" value="Delete Item" />

What does the value of "submit" come up to be in the PHP script after you post it?

echo $_POST ['submit'];

If it can distinguish what button has been pressed, then you could do the following,

if ($_POST ['submit'] == "Update Item") {

  //Code for update
}

else if ($_POST ['submit'] == "Delete Item") {

  //Code for delete
}

oh ... sorry Caiapfas, I just have been really busy, and I forgot about the question you asked. I would have answered your question, if I was given a reminder .. i guess a C is better than nothing ..

anyway, I hope you solved the problem.
