pagination - need help on passing of search query.

Posted on 16th Feb 2014 by admin

Hi, i have been trying for days but couldn't get this sorted out. Would like some professional help here.
Basically I got a basic pagination script from google search and the script works absolutely well if i am to display the full results.
However i am using the 'SELECT...WHERE.. LIKE %$val%' and the result works well for the 1st page but not on the 2nd or 3rd page. i had a search form to submit my value. Some help as to where i should proceed is greatly appreciated! Cheers
Here's my coding:

form.php
Code: <form action="FTsearch.php" method="post">
<table border=0 cellspace=1 cellpadding=3 bgcolor;"#353535"
align="center">
<tr>
<td bgcolor="#eeeeff" width="50%">
Device Number
</td>
<td bgcolor="#eeeeff" width="50%">
<INPUT type = "TEXT" name = "devicesearch">
</td>
</tr>
<tr>
<td bgcolor ="eeeeff" colspan=2 align="center">
<INPUT Type="SUBMIT" name="submit" value="Device Search">
</td>
</tr>
</table>
</form>
FTsearch.php
Code: $val_d = $_POST['devicesearch'];

if ($_POST['SEARCH'] = 'Device Search')
{
$sql = "SELECT *
FROM device
WHERE device_num LIKE '%$val_d%' or '%$val_d'";

$results1 = mysql_query($sql) or die ("Sorry no match found!".mysql_error());

//This checks to see if there is a page number. If not, it will set it to page 1
if (!(isset($pagenum)))
{
$pagenum = 1;
}
$pagenum = $_GET['pagenum'];
echo "<center>";


/* if(!isset($_GET['page'])) {
$pagenum = 1;
} else {
$pagenum = $_GET['page'];
} */

$numrows = mysql_num_rows($results1);
$page_rows = 10; //This is the number of results displayed per page
$last = ceil($numrows/$page_rows); //This tells us the page number of our last page

if ($pagenum < 1) //this makes sure the page number isn't below one, or more than our maximum pages
{
$pagenum = 1;
}
elseif ($pagenum > $last)
{
$pagenum = $last;
}

$max = 'limit ' .($pagenum - 1) * $page_rows .',' .$page_rows; //This sets the range to display in our query

$sql = "SELECT *
FROM device
WHERE device_num LIKE '%$val_d%' or '%$val_d' $max";
$results = mysql_query($sql) or die (mysql_error());

// this is the result display
include "FTsearchtable.php";


echo "

<center>Page $pagenum of $last

"; // This shows the user what page they are on, and the total number of pages

// First we check if we are on page one.
//If we are then we don't need a link to the previous page or the first page so we do nothing.
//If we aren't then we generate links to the first page, and to the previous page.
if($pagenum>1)
{

echo " <a href='{$_SERVER['PHP_SELF']}?&pagenum=1'>First</a> ";
$previous = $pagenum-1;
echo " <a href='{$_SERVER['PHP_SELF']}?&pagenum=$previous'>Previous</a> ";
}
//This does the same as above, only checking if we are on the last page, and then generating the Next and Last links
if ($pagenum == $last)
{
}
else
{
$next = $pagenum+1;
echo " <a href='{$_SERVER['PHP_SELF']}?&pagenum=$next'>Next</a> ";
echo " ";
echo " <a href='{$_SERVER['PHP_SELF']}?&pagenum=$last'>Last</a> ";
}

}
