Question

我有分页搜索，搜索功能正常，分页也很好但我真正的问题是我不知道如何合并这两个。每次我尝试搜索时，搜索结果都会显示，但分页不正常。请有人帮我解决这个问题。我不知道从哪里开始。

我有这段代码：

<?php

$con = mysql_connect("localhost","root","");
if (!$con) {
die('Could not connect: ' . mysql_error());
}

mysql_select_db("region_survey", $con);

$sql="SELECT * FROM municipality";




if(isset($_POST['search'])){

$search_term=mysql_real_escape_string($_POST['search_box']);

$sql .= " WHERE province_id LIKE '%{$search_term}%' ";

}

$query=mysql_query($sql) or die (mysql_error());


?>

<form name="search_form" method="POST" action="">

Search:<input type="text" name="search_box" value="" />
<input type="submit" name="search" value="search the table" />

</form>

<body>
<?php
//Include the PS_Pagination class
include('ps.php');

//Connect to mysql db
$conn = mysql_connect('localhost','root','');
if(!$conn) die("Failed to connect to database!");
$status = mysql_select_db('region_survey', $conn);
if(!$status) die("Failed to select database!");
$sql = 'SELECT * FROM municipality';



//Create a PS_Pagination object
$pager = new PS_Pagination($conn, $sql, 15, 17);

//The paginate() function returns a mysql result set for the current page
$rs = $pager->paginate();
?>

<?php
$con = mysql_connect("localhost","root","");
if (!$con) {
die('Could not connect: ' . mysql_error());
}
//Count total number of records after search
mysql_select_db("region_survey", $con);

if(isset($_POST['search'])){

$search_term=mysql_real_escape_string($_POST['search_box']);


$sql="SELECT * FROM municipality WHERE province_id LIKE '%$search_term%'";

}

$result = mysql_query($sql, $con);
$row = mysql_num_rows($result);

echo "Total Number: ";
echo $row;
?>


<table border="1" cellpadding="0" cellspacing="0" id="resultTable">
        <tr>
          <th> <strong>ID</strong> </th>
          <th> <strong>Province ID</strong> </th>
          <th> <strong>Municipality Name</strong> </th>
        </tr>
<?php
while($row = mysql_fetch_array($query))

{
?>
<tr>
<td> <?php echo $row["id"]; ?> </td>
<td> <?php echo $row["province_id"]; ?></td>
<td> <?php echo $row["municipality_name"]; ?></td>
<td><input name="selector[]" type="checkbox"
id="checkbox[]" value="<?php echo $row['id'];?>"></td>
        <td><a href="update.php<?php echo '?id='.$row['id']; ?>">Edit</a>        </td>
</tr>
<?php
}
?>
   </table>    

   <?php
//Display the navigation
//echo $pager->renderFullNav();
echo '<div style="text-align:center">'.$pager->renderFullNav().'</div>';
?>
</body>
</html>

网页会有example.com/search/term/?page=2（或example.com/search.php?term=xyz&page=2这样的网址，如果您重定向网址，则无关紧要。）

在PHP中，它将类似于：

$pagelimit = 10; // records per page
$page = isset($_GET['page']) ? (int)$_GET['page'] : 1; // set current page

您的SQL查询中LIMIT OFFSET：

$sql = "SELECT * 
        FROM municipality 
        WHERE province_id LIKE '%$search_term%' 
        LIMIT " . ($page - 1) * $pagelimit . ", " . $pagelimit;

用分页搜索
