php mysql在表结果上的过滤选项

Question

当前，我有一个带有相应搜索结果的呈现表。我的问题，我如何添加一个过滤器选项，将过滤一个特定的领域，但只有当该表格呈现超过25个结果？

<?php 

$button = $_GET ['submit']; 
$search = $_GET ['search']; 

if(strlen($search)<=1) 
echo "Search term too short"; 
else{ 
mysql_connect("*******.lininteractive.com","**********","********"); 
mysql_select_db("admin_diceydining"); 

$search_exploded = explode (" ", $search); 

$x = ""; 
$construct = ""; 

foreach($search_exploded as $search_each) 
{ 
$x++; 
if($x==1) 
$construct .="Name LIKE '%$search_each%'"; 
else 
$construct .="AND PCITY LIKE '%$search_each%'"; 

} 

$constructs ="SELECT * FROM broadway WHERE $construct"; 
$run = mysql_query($constructs); 

$foundnum = mysql_num_rows($run); 

if ($foundnum==0) 
echo "Sorry, there are no matching result for <b>$search</b>.</br></br>1. 
Try more general words. for example: If you want to search 'how to create a website' 
then use general keyword like 'create' 'website'</br>2. Try different words with similar 
meaning</br>3. Please check your spelling"; 
else 
{ 


$per_page = 25; 
$start = isset($_GET['start']) ? $_GET['start']: ''; 
$max_pages = ceil($foundnum/$per_page); 
if(!$start) 
$start=0; 
$getquery = mysql_query("SELECT * FROM broadway WHERE $construct LIMIT $start, $per_page"); 

    echo "<table data-toggle='table' data-sort-name='name' data-sort-order='desc'>"; 
    echo "<thead>"; 
    echo "<tr>"; 
    echo "<th data-sortable='true'>Date</th><th data-field='Name' data-align='left' data-sortable='true'>Name</th><th>City</th><th>Description</th>"; 
    echo "</tr>"; 
    echo "</thead>"; 

    while($runrows = mysql_fetch_assoc($getquery)) { 
    // $results = mysql_fetch_array($raw_results) puts data from database into array, while it's valid it does the loop 
    echo "<tr>"; 
    echo "<td>{$runrows['Name']}</td>"; 
    echo "<td>{$runrows['PCITY']}</td>"; 
    echo "<td>{$runrows['TYPE']}</td>"; 
    echo '<td><a href="results2.php?nameID=' .$runrows['ID'].'">' .substr($runrows['DESCR'], 0, 35) .'</a></td>'; 
    echo "</tr>"; 
    // posts results gotten from database(title and text) you can also show id ($results['id']) 

    } 

    echo "</table>";

您可以执行一个查询像

SELECT COUNT（*）FROM百老汇计算的结果，其中$结构;

当您知道结果的行号后，您可以选择要执行的操作。
