Hey everyone, I’m working on an e-commerce site and I’m stuck with the product editing feature. The update query isn’t working as expected. Here’s a simplified version of my code:
if(isset($_GET['update'])) {
$updateQuery = "UPDATE items SET name = ?, cost = ?, details = ?, group = ?, picture = ? WHERE item_id = ?";
$stmt = $connection->prepare($updateQuery);
$stmt->bind_param("sssssi", $name, $cost, $details, $group, $imagePath, $itemId);
$stmt->execute();
}
The issue is that changes only stick if I modify the image. If I just update text fields, the changes don’t save. I’m on a tight deadline and could really use some help. Any ideas on what might be causing this? Thanks in advance!
Hey there, ClimbingMountain! Your issue sounds pretty frustrating, especially with a deadline looming. Have you considered that the problem might be in how you’re handling the form data before it reaches this query?
I’m curious - are you using the same form for both text updates and image uploads? If so, maybe the form’s enctype is set to ‘multipart/form-data’ for file uploads, which could be affecting how non-file data is processed.
Also, just throwing this out there - could it be that your ‘group’ column name is conflicting with a MySQL reserved keyword? That might cause some weird behavior.
Oh, and one more thing - have you tried echoing out the values of your variables right before the query runs? That could give you a clue if the data is actually making it to this point in your code.
Let us know what you find out! I’m really interested to see what the root cause turns out to be. Good luck with your deadline!
I’ve encountered a similar issue before. The problem might be in your form submission logic, not necessarily the SQL query. Check if you’re properly handling form submissions without file uploads. Often, developers use different methods for handling file uploads vs. regular form data, which can lead to this behavior.
Also, ensure all your form fields have the ‘name’ attribute correctly set and that they match the variables in your PHP script. Sometimes, a mismatch here can cause only certain fields to update.
Lastly, add some error checking after your execute() call. Use $stmt->error to see if there are any SQL errors that might provide more insight. This approach helped me diagnose a similar problem in one of my projects.
