<?php
$per_page = 35;
$page = 1;
if (isset($_GET['page']))
{
$page = intval($_GET['page']);
if($page < 1) $page = 1;
}
$start_from = ($page - 1) * $per_page;
$con= mysql_connect("localhost","sarya_asad","Thisisfor123");
mysql_select_db('saryaal_com_movies',$con);
$current_items = mysql_query( "SELECT * FROM `english` LIMIT $start_from, $per_page");
if( mysql_num_rows($current_items) > 0)
{
while($item = mysql_fetch_assoc($current_items))
{
?>
<tr>
<td> <strong><a href="english/english-preview.php?id=<?php echo$item['id']?>" ><?php echo $item['title'] ;?></a> </strong></td>
<td> <strong> <?php echo $item['year'] ;?> </strong></td>
<td> <strong> <?php echo $item['quality'] ;?> </strong> </td>
</tr>
<tr><td>
<?php
}
}
else
{
echo 'this page does not exists';
}
$total_rows = mysql_query("SELECT COUNT(*) FROM `english`");
$total_rows = mysql_fetch_row($total_rows);
$total_rows = $total_rows[0];
$total_pages = $total_rows / $per_page;
$total_pages = ceil($total_pages); # 19/5 = 3.8 ~=~ 4
for($i = 1; $i <= $total_pages; ++$i)
{
echo "<a href='temp2.php?page=$i' class='pagNumActive'>$i</a> ";
}
?>

<?php if($Strkeyword=="" AND $StrLoc=="" AND $StrMinsal=="-1" AND $StrMaxsal=="-1" AND $StrMax_exp=="maximum" AND $Strcategory=="" AND $Strjobtype=="") {
$sql=mysql_query("select * from job where AND status='Active'");
}
$per_page = 5;
$page = 1;
if (isset($_GET['page'])) {
$page = intval($_GET['page']);
if($page < 1) $page = 1;
}
$start_from = ($page - 1) * $per_page;
if($Strkeyword=="" AND $StrLoc=="" AND $StrMinsal=="-1" AND $StrMaxsal=="-1" AND $StrMax_exp=="maximum" AND $Strcategory=="" AND $Strjobtype=="")
{
$current_items=mysql_query("select * from job LIMIT $start_from, $per_page"); } $start_from, $per_page");

<?php include("include/result.php") ?>// result u want to display
<?php

Answer 2

This is your problem:
$con= mysql_connect("localhost","sarya_asad","Thisisfor123");
mysql_select_db('saryaal_com_movies',$con);
You need to change the host details. localhost is the local server on your machine.

Answer 3

change this
$start_from = ($page - 1) * $per_page;
to
$start_from = ($page) * $per_page;

Answer 4

you might want to use something like:
$per_page = 35;
$start_from = $page * $per_page - $per_page;

Answer 5

Try this logic for pagination:
Your goal is to offset by the number of images you want to display on each page.
So let's say you want to display 6 movie thumbnails on a page... You'd have:
$videos_per_page = 6
$pageNumber = (isset($_GET['page']) ? ($_GET['page']) : 1);
And your offset would be:
$offset = $videos_per_page * $pageNumber
(6 videos * page 0... so you're offsetting 0 videos. That's good because you want to display the first 6 videos in your data structure on page 0).
So now that you have your offset value... You need to set your array pointer to the correct spot... Loop through your database rows storing your movies and move your pointer by your offset value... Store that in $videos_to_offset...
while ($videos_per_page < $offset && ($row = $Query_Result->fetch_assoc())) {
$videos_to_offset++;
}
Now you can loop through your database rows, outputting your videos from wherever your offset array pointer left off:
$video_counter = 0;
while ($video_counter < $videos_per_page && ($row = $Query_Result->fetch_assoc())) {
echo $row['videopath'];
$video_counter++;
}
Something like that.
