Pagination in search php - php

Question

I have a search form and i want to put a pagination, but when i press the next button or second page on the search using pagination , all the results get messed up, and there is no data being fetched from the query. I don't know where the exact problem could be, but this is my search code:
include ('paginate.php'); //include of paginat page
$per_page = 5;
$find = $_POST['find'];
$find = strtoupper($find);
$find = strip_tags($find);
$find = trim ($find); // number of results to show per page
$result = mysql_query("SELECT * FROM projects WHERE p_name LIKE '%$find%'");
$total_results = mysql_num_rows($result);
$total_pages = ceil($total_results / $per_page);//total pages we going to have
//------------if page is setcheck-----------------//
if (isset($_GET['page'])) {
$show_page = $_GET['page']; //it will telles the current page
if ($show_page > 0 && $show_page <= $total_pages) {
$start = ($show_page - 1) * $per_page;
$end = $start + $per_page;
} else {
// error - show first set of results
$start = 1;
$end = $per_page;
}
} else {
// if page isn't set, show first set of results
$start = 0;
$end = $per_page;
$show_page=1;
}
// display pagination
if(isset($_GET['page'])){
$page = intval($_GET['page']);
}else{
$page =1;
}
$tpages=$total_pages;
if ($page <= 0)
$page = 1;
?>
<?php
$reload = $_SERVER['PHP_SELF'] . "?tpages=" . $tpages;
echo '<div class="pagination"><ul>';
if ($total_pages > 1) {
echo paginate($reload, $show_page, $total_pages);
}
echo "</ul></div>";
// display data in table
echo "<table class='table table-bordered'>";
echo "<thead><tr><th>Project</th> <th>Country</th> <th>Active</th>
</tr></thead>";
for ($i = $start; $i < $end; $i++) {
// make sure that PHP doesn't try to show results that don't exist
if ($i == $total_results) {
break;
}
?><form name="frmactive" method="POST" action="">
<input type="hidden" name="id" value="<?php echo mysql_result($result, $i, 'p_id');?>" />
<?php
// echo out the contents of each row into a table
echo '<tr><td>' . mysql_result($result, $i, 'p_name') . '</td>';
echo '<td>' . mysql_result($result, $i, 'p_country') . '</td>';
if (mysql_result($result, $i, 'p_isActive')=='1'){
echo '<td>Active</td>';
echo '<td align="center">Edit</td>';
}
else{
echo'<td>Inactive</td> ';
echo '<td align="center">Edit</td>';
echo "</tr>";
}
// close table>
}
echo "</table>";
// pagination
?>
and this is the paginate.php
function paginate($reload, $page, $tpages) {
$adjacents = 2;
$prevlabel = "‹ Prev";
$nextlabel = "Next ›";
$out = "";
// previous
if ($page == 1) {
$out.= "<span>" . $prevlabel . "</span>\n";
} elseif ($page == 2) {
$out.= "<li>" . $prevlabel . "\n</li>";
} else {
$out.= "<li>" . $prevlabel . "\n</li>";
}
$pmin = ($page > $adjacents) ? ($page - $adjacents) : 1;
$pmax = ($page < ($tpages - $adjacents)) ? ($page + $adjacents) : $tpages;
for ($i = $pmin; $i <= $pmax; $i++) {
if ($i == $page) {
$out.= "<li class=\"active\"><a href=''>" . $i . "</a></li>\n";
} elseif ($i == 1) {
$out.= "<li>" . $i . "\n</li>";
} else {
$out.= "<li>" . $i . "\n</li>";
}
}
if ($page < ($tpages - $adjacents)) {
$out.= "<a style='font-size:11px' href=\"" . $reload . "&page=" . $tpages . "\">" . $tpages . "</a>\n";
}
// next
if ($page < $tpages) {
$out.= "<li>" . $nextlabel . "\n</li>";
} else {
$out.= "<span style='font-size:11px'>" . $nextlabel . "</span>\n";
}
$out.= "";
return $out;
}
Could you please point out where the bug is taking place ? Thank you for your time

Try this (pay attention to the comments please) :
<?php
/*
Assuming that your search form has a POST method set to it,
be sure to do a redirect to this page and send the find parameter gotten
from the posted form urlencoded
ie path_to_my_file?find='.urlencode(trim($_POST['find']))
*/
include ('paginate.php'); //include of paginat page
$per_page = 5;
$find = strip_tags(strtoupper(trim(urldecode($_GET['find']))));
$page = intval($_GET['page']);
$result_total = mysql_query("SELECT COUNT(*) AS total FROM projects WHERE p_name LIKE '%".$find."%'");
$tmp_total = mysql_fetch_assoc($results_total);
$totalpages = ceil($tmp_total['total'] / $per_page);
if ($totalpages != 0 && $page > $totalpages) {
$page = $totalpages;
} else if ($page < 1) {
$page = 1;
}
$offset = ($page - 1) * $per_page;
$result = mysql_query("SELECT * FROM projects WHERE p_name LIKE '%".$find."%' LIMIT ".$offset.", ".$per_page);
$show_page = 1;
//You need to pass the phrase you are searching for in every link in order for the pagination to work (or user Sessions to save the keyword somewhere if you don't want it in the link)
$reload = $reload = 'http://localhost/Personal/Stackoverflow/2/index.php?find='.urlencode($find);
echo ' <div class="pagination">
<ul>';
if ($totalpages > 1) {
echo paginate($reload, $show_page, $totalpages);
}
echo ' </ul>
</div>';
// display data in table
if(mysql_num_rows($result) > 0) {
echo ' <table class="table table-bordered">
<thead>
<tr>
<th>Project</th>
<th>Country</th>
<th>Active</th>
</tr>
</thead>';
while($row = mysql_fetch_assoc($result)) {
echo ' <tr>
<td>'.$row['p_name'].'</td>
<td>'.$row['p_country'].'</td>
<td>'.((intval($row['p_isActive']) == 1) ? 'Active' : 'Inactive').'</td>
<td align="center">
Edit
</td>
</tr>';
}
echo ' </table>';
}
?>
