this is my first post here at Stack Overflow. I know the question has been asked many times before. I went through many answers, tried all of them (except the correct approach obviously) and don't know what to try anymore.
I have an SQL table where every row has an "edit" button. When clicking it, I pass over the id of the selected row to edit.php. There, I get it and update the given row based on the id with the user input from the form. The first column is id which is set to AUTO_INCREMENT.
On a side note, I get the same error, no matter if I use WHERE id=$id"; or WHERE id='$id'";
The code which I think is closest to the correct approach is as follows and generates the error message below the code:
<html>
<title>
Video Archiv - New
</title>
<body>
<?php
include("connect.php");
$id=$_GET['id'];
echo "Details von Video #$id editieren:<br /><br />";
if(isset($_POST['update']))
{
$sql = "UPDATE VideoArchiv
SET ('".$_POST["titel"]."','".$_POST["schauspieler"]."')
WHERE id=$id";
$result = mysqli_query($connect,$sql);
if (mysqli_query($connect,$sql) === TRUE)
{
echo "Record updated successfully";
}
else
{
echo "Error updating record: " . $connect->error;
}
}
?>
<form action="edit.php" method="post">
<label> Titel:</label><br/>
<input type="text" name="titel" required><br/>
<label>Schauspieler</label><br/>
<input type="text" name="schauspieler" required><br/>
<br />
<button type="submit" name="update">Speichern</button>
</form>
<?php
include("back.php");
?>
</body>
</html>
Error message:
Error updating record: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '('a','d') WHERE id=9' at line 2
Thanks a lot for your help and sorry for the duplicate question, but I really can't find the solution and am pretty desperate.
UPDATE:
The following code gives this error:
Fatal error: Uncaught Error: Call to a member function bind_param() on bool in /homepages/25/d72758610/htdocs/multimedia/edit.php:30 Stack trace: #0 {main} thrown in /homepages/25/d72758610/htdocs/multimedia/edit.php on line 30
