Posted: Sat Apr 10, 2010 3:33 am
Hi I wanted to implement pagination on my website... Its driven by mysql and php....I found some scripts online to do this and have been unsuccesful so far...I have pasted the code below....I would appreciate it if someone could take a look and tell me what is it that I am doing wrong
Code: Select all
<?php
include("includes/db.php");
mysql_connect($host,$username,$password);
@mysql_select_db($database) or die( "Unable to select database");
if ($dept != "" and $dept == "0")
{
$srch = "Department";
$query2 = "SELECT * FROM articles WHERE cat='2' and descr LIKE
'%$srch%' ORDER by id DESC";
}
if ($dept != "" and $dept == "1")
{
$srch = "Internal Medicine";
$query2 = "SELECT * FROM articles WHERE cat='2' and descr LIKE
'%$srch%' ORDER by id DESC";
}
else if ($dept != "" and $dept == "2")
