This is a pagination script, with a delete function and is in a table. I am getting this error.

Code:

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 '-4,4' at line 1

What is the problem? And how can I fix it?

"-4,4" is your problem

You need to fix whatever is going wrong with $delete

**sith717** · 11-03-2009, 11:49 AM

Okay I have updated the code replacing it with this:

Change this line

PHP Code:


			
$data_p = mysql_query("SELECT * FROM accounts $max") or die(mysql_error());

to this

PHP Code:


			
$data_p = mysql_query("SELECT * FROM accounts $max") or die("SELECT * FROM accounts $max");

It is now showing this error:

Code:

PHP Code:


			
SELECT * FROM accounts limit -4,4

This is the updated code.

PHP Code:


			
<?php
include("inc/config.php");
if (isset($_POST['del'])) 
{
  for ($count = 0;$count<count($_POST[delchk]);$count++)
   {
           $delete = $_POST[delchk][$count];
           $query = "DELETE FROM accounts WHERE id = '$delete'";
           $result = mysql_query($query);
           if (!$result)

Do the same thing for these rows

PHP Code:


			
$query = "DELETE FROM accounts WHERE id = '$delete'";
$result = mysql_query($query);

That is, change into this

PHP Code:


			
$query = "DELETE FROM accounts WHERE id = '$delete'";
$result = mysql_query($query) or die($query);

Okay I have fixed that. I am now getting this error:

?>

what do I do to fix that? also, it shows this
when there are no records in the database:

Picture:

See the:

1 | 2 | Last

Its supposed to hide when there are no records.

Can someone help me out?
