How do i make delete button work? - php

Question

I am trying to make a delete button but it doesn't work.
$interogare = "SELECT * FROM comments JOIN users ON users.user_id = comments.user_id WHERE movie_id='$movie_id' ORDER BY date_posted DESC";
$result = mysqli_query($dbc, $interogare) or die(mysqli_error($dbc));
while($rand = mysqli_fetch_assoc($result))
{
echo 'Delete';
if(isset($_GET['com'])) {
$haidi = mysqli_real_escape_string($dbc,$_GET['com']);
$sql_del = "DELETE FROM comments WHERE comment_id = '$haidi'";
mysqli_query($dbc,$sql_del);
header('location: film.php?id='.$_GET['id'].'');
exit();
}
}
When i click the delete link it takes me to
film.php?com='.$rand['comment_id'].'
page but nothing happens,it should delete my comment and take me back to the page where the comment was.Can someone please help me figure this out ?

Answer 1

does this work?
<?php
$query = "
SELECT *
FROM comments
JOIN users ON users.user_id = comments.user_id
WHERE movie_id=" . $movie_id . "
ORDER BY date_posted DESC";
$result = mysqli_query($dbc, $query) or die(mysqli_error($dbc));
if (isset($_GET)) {
$getData = $_GET;
}
while ($rand = mysqli_fetch_assoc($result))
{
echo 'Delete';
if (isset($getData) && $getData['com']) {
$id = mysqli_real_escape_string($dbc, $getData['com']);
$query = "
DELETE FROM comments
WHERE comment_id=" . $id;
$result = mysqli_query($dbc, $query);
if($result)
{
header('location: film.php?id=' . $id . '');
}
exit();
}
}
i would rather grab the post once, and then make sure we are passing the same object around, so i set GET to a var. then, i didnt like the way the ids were being set in the query, because it wasnt as easy to see. then i got down to the way you were creating the header, and it looked like you were passing the id from some GET data, instead of the id you just extracted and set to a varibale, see above..., or was that your intention to use $_GET['id'] for that actually instead?
also, you might need to pass your data link in the mysqli_real_escape_string() method
