分頁搜索php

Question

我有一個搜索表單，我想分頁，但是當我按分頁搜索的下一個按鈕或第二頁，所有的結果搞砸了，沒有數據被取出來自查詢。我不知道確切的問題可能是，但是這是我的搜索代碼：

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, $i, 'p_isActive')=='1'){ 
         echo '<td>Active</td>'; 
         echo '<td align="center"><a href="activeproject.php?id=' . mysql_result($result, $i, 'p_id') . '">Edit</a></td>'; 
} 
else{ 
    echo'<td>Inactive</td> '; 
    echo '<td align="center"><a href="activeproject.php?id=' . mysql_result($result, $i, 'p_id') . '">Edit</a></td>'; 
         echo "</tr>"; 
        }  
        // close table> 
        } 
       echo "</table>"; 
      // pagination 
      ?> 

，這是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><a href=\"" . $reload . "\">" . $prevlabel . "</a>\n</li>"; 
    } else { 
     $out.= "<li><a href=\"" . $reload . "&amp;page=" . ($page - 1) . "\">" . $prevlabel . "</a>\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><a href=\"" . $reload . "\">" . $i . "</a>\n</li>"; 
     } else { 
      $out.= "<li><a href=\"" . $reload . "&amp;page=" . $i . "\">" . $i . "</a>\n</li>"; 
     } 
    } 

    if ($page < ($tpages - $adjacents)) { 
     $out.= "<a style='font-size:11px' href=\"" . $reload . "&amp;page=" . $tpages . "\">" . $tpages . "</a>\n"; 
    } 
    // next 
    if ($page < $tpages) { 
     $out.= "<li><a href=\"" . $reload . "&amp;page=" . ($page + 1) . "\">" . $nextlabel . "</a>\n</li>"; 
    } else { 
     $out.= "<span style='font-size:11px'>" . $nextlabel . "</span>\n"; 
    } 
    $out.= ""; 
    return $out; 
} 

可否請你指出其中的錯誤正在發生？感謝您的時間

試試這個（注意意見請）：在查詢

<?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);
