Need help with pagination

Post by irti_h »

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")
{
$srch = "Cardiology";
$query2   = "SELECT * FROM articles WHERE cat='2' and descr LIKE
'%$srch%' ORDER by id DESC";
}
else if ($dept != "" and $dept == "3")
{
$srch = "Pediatrics";
$query2   = "SELECT * FROM articles WHERE cat='2' and descr LIKE
'%$srch%' ORDER by id DESC";
}
else if ($dept != "" and $dept == "4")
{
$srch = "General Surgery";

'%$srch%' ORDER by id DESC";
}
else if ($dept != "" and $dept == "5")
{
$srch = "Orthopedics";

1. You didn't really identify what is failing. That would be helpful.
2. I don't understand why you're breaking in and out of php. (<? .... ?>). It seems unnecessary for what you're doing.
3. Your last line seems very strange "<?=$pagination?>" ??? huh? What = $pagination?

Please be more specific. Thanks.
