You have two add_topic.php should one be add_ans.php
I don't see any exact problems with this code are you sure that the $id is being used correctly in the hidden field of your form?
Possibly try doing a print_r($_POST); on the add_ans.php page to see what data is actually being passed by the form

I'm learning php, now I'm trying to get use with databases and etc stuff. My code (that is below) seems that is not working, and I can't solve it out why. It looks good but still after pushing "delete" nothing happens. Maybe you will be able to help me. Thanks in advance.

Your form's action field is empty. You have to get fields from form with php "$checkbox = $_POST['checkbox']". After you can do like you do, or you can write other mysql query " DELETE FROM YOUR_TABLE WHERE id in (1,2,3,4) ".
I know there are questions similar, but I am unable to determine my issue with my PHP code. I am trying to remove a student from an intermediary table between Student table and Class table, called Student_has_Class. The SQL code works, just not the page. It lists the students in the table successfully, but when I check the box by a student to remove them and click submit, it redirects to same page (basically a refresh) like it is supposed to (even though it doesn't reload the table for some reason), and the student is still in the Student_has_Class table. Please help, as posting online is a last resort for me.
Please take a look a the code:
Note: I removed some login and web address info for privacy. Indicated with { }.
<?php
// Connects to your Database
session_start();
$x = $_SESSION['user'];
$y = $_GET['id'];
mysql_connect("{removed site for privacy}", "{username removed}", "{password removed}") or die(mysql_error
());
mysql_select_db("test") or die(mysql_error());
if (isset($_POST['delete']))
{
if (isset($_POST['checkbox']))
{
$checkbox = $_POST['checkbox'];
if (is_array($checkbox)) {
foreach ($checkbox as $key => $x)
{
$mysql->query("DELETE FROM Student_has_Class WHERE User_idUser='$x'");
}
}
}
}
?>
<?php
$sql = "SELECT User.idUser, User.UserFirstName, User.UserLastName
FROM Student_has_Class
INNER JOIN User ON User.idUser = Student_has_Class.User_idUser AND User.Role = 'Student'
INNER JOIN Class ON Class.idClass = Student_has_Class.Class_idClass
WHERE Student_has_Class.Class_idClass = 2 AND Class.User_idUser = ".$x."
ORDER BY User.UserLastName";
$result = mysql_query($sql);
$count = mysql_num_rows($result);

Update:
I used Internet Explorer debugger to get some info that Chrome debugger doesn't provide. Here is the page, notice the values in the checkboxes. I'm not sure if that is correct.

Update:
The POST parameters are as follows when I try to delete the third person in the table by checking the checkbox to the left of their name, and clicking the Delete button (previously called Submit button). The person to delete has a User ID of 12.
Array ( [checkbox] => Array ( [2] => ) [hiddencounter] => 5 [delete] => Delete )
You can try this. But I will change your code from MySQL to MySQLi.
<?php
// Connects to your Database
session_start();
$x = $_SESSION['user'];
$y = $_GET['id'];
/* ESTABLISH CONNECTION */
$connect=mysqli_connect("YourHost","YourUsername","YourPassword","YourDatabaseName"); /* REPLACE THE NECESSARY HOST, USERNAME, PASSWORD, AND DATABASE */
if(mysqli_connect_errno()){
echo "Error".mysqli_connect_error();
}
if (isset($_POST['delete'])){ /* IF DELETE IS SET/CLICKED */
$counter=mysqli_real_escape_string($connect,$_POST['hiddencounter']);
$checkbox=$_POST['checkbox'];
for($x=0;$x<=$counter;$x++){
if(!empty($checkbox[$x])){ /* IF SELECTED ITEM */
$checked=mysqli_real_escape_string($connect,$checkbox[$x]);
mysqli_query($connect,"DELETE FROM Student_has_Class WHERE User_idUser='$checked'");
} /* END OF IF NOT EMPTY CHECKBOX SELECTED */
} /* END OF FOR LOOP */
} /* END OF ISSET DELETE */
?>
<?php
$sql = "SELECT User.idUser, User.UserFirstName, User.UserLastName

So, I'm adding a forum section to my site. So far, everyone thing is good. You can create a topic, view a list of topics, but when you go to view a topic (which is view_topic.php?id=#) this keeps appearing:
Parse error: syntax error, unexpected $end in /home/papervip/public_html/forums/questions/view_topic.php on line 158
So, here's the full script of view_topic.php (without the database credentials included, so I can ensure my security :D ):
<?php
session_start();
$host="localhost"; // Host name
$username=""; // Mysql username
$password=""; // Mysql password
$db_name=""; // Database name
$tbl_name="forum_questions"; // Table name
// Connect to server and select databse.
mysql_connect("$host", "$username", "$password")or die("cannot connect");
mysql_select_db("$db_name")or die("cannot select DB");
// get value of id that sent from address bar
$id=$_GET['id'];
$sql="SELECT * FROM $tbl_name WHERE id='$id'";
$result=mysql_query($sql);
$rows=mysql_fetch_array($result);

I've re-read the entire file about 10 times now, but it still keeps stating the final closing html tag as a unexpected $end. Am I overlooking something? Thanks in advance.
I believe you have an unmatched { here:

} // It looks like this is missing

You're trying to reuse your MySQL connection while still holding on to the resultset from the first query. You need to create a second connection for the inner loop queries. Even better would probably be to rewrite your query using a join, but I can't say for sure without knowing your schema.
Can any one tell what is happening with my code? I got this code from web but its not working; when I press delete its not deleting the database. Can you help me?
<?php
$host="localhost"; // Host name
$username="root"; // Mysql username
$password=""; // Mysql password
$db_name="comment";
$tbl_name="members";
mysql_connect($host, $username, $password)or die("cannot connect");
mysql_select_db($db_name)or die("cannot select DB");
$sql="SELECT * FROM $tbl_name";
$result=mysql_query($sql);
$count=mysql_num_rows($result);
?>
<table width="400" border="0" cellspacing="1" cellpadding="0">
<tr><td><form name="form1" method="post" action="">
<table width="400" border="0" cellpadding="3" cellspacing="1" bgcolor="#CCCCCC"><tr>
<td bgcolor="#FFFFFF"> </td>
<td colspan="4" bgcolor="#FFFFFF"><strong>Delete multiple rows in mysql</strong> </td></tr>
<tr><td align="center" bgcolor="#FFFFFF">#</td>
<td align="center" bgcolor="#FFFFFF"><strong>Id</strong></td>
< td align="center" bgcolor="#FFFFFF"><strong>Name</strong></td>
<td align="center" bgcolor="#FFFFFF"><strong>Lastname</strong></td>
<td align="center" bgcolor="#FFFFFF"><strong>Email</strong></td></tr>
<?php while($rows=mysql_fetch_array($result, MYSQL_ASSOC)){ ?>
<tr><td align="center" bgcolor="#FFFFFF">
<input name="checkbox[]" type="checkbox" id="checkbox[]" value="<? echo $rows['id']; ?>">
</td><td bgcolor="#FFFFFF"><?php echo $rows['id']; ?></td><td bgcolor="#FFFFFF">
<?php echo $rows['firstname']; ?></td><td bgcolor="#FFFFFF"><?php echo $rows['lastname']; ?></td>
<td bgcolor="#FFFFFF"><?php echo $rows['passwd']; ?>
</td></tr>
<?php } ?>
<tr><td colspan="5" align="center" bgcolor="#FFFFFF">
<input name="delete" type="submit" id="delete" value="Delete"></td></tr>
</table></form></td></tr></table>
<?php
$checkbox = $_POST['checkbox'];
$delete = $_POST['delete'];
if(isset($delete)){
for($i=0;$i<$count;$i++){
$del_id = $checkbox[$i];
$sql = "DELETE FROM $tbl_name WHERE id='$del_id'";
$result = mysql_query($sql);
}
if($result){echo "<meta http-equiv=\"refresh\" content=\"0;URL=delete.php\">";}}
mysql_close();
?>
Please correct the form action to work the code
<?php

$username="root"; // Mysql username
$password=""; // Mysql password
$db_name="comment";

mysql_connect($host, $username, $password)or die("cannot connect");
mysql_select_db($db_name)or die("cannot select DB");
