Question

使用php创建一个新项目：使用搜索功能（search.php）从mysql数据库中检索数据 - 在结果页面（find.php）上添加了对搜索结果的分页。问题是，当显示第一次搜索时，它显示正确的数据;但是，当我点击第二页（分页按钮）时，它会再次填充所有数据 - 而不是我搜索的术语：请帮忙！

的search.php

<form action="find.php" method="post">
<input name="search" type="search" autofocus><input type="submit" name="button">
</form>

find.php

<?php

include_once("config.php");


if(isset($_POST['button'])){ 
    $search=$_POST['search'];
}

$result = mysql_query(" SELECT * FROM bra_list WHERE locations like '%{$search}%' $limit "); 
$row = mysql_num_rows($result);
$page_rows = 3;
$last = ceil($row/$page_rows);

if($last < 1){
    $last = 1;
}
$pagenum = 1;

if(isset($_GET['page'])){
    $pagenum = preg_replace('#[^0-9]#', '', $_GET['page']);
}

if ($pagenum < 1) { 
    $pagenum = 1; 
} else if ($pagenum > $last) { 
    $pagenum = $last; 
}

$limit = 'LIMIT ' .($pagenum - 1) * $page_rows .',' .$page_rows;

$result = mysql_query(" SELECT * FROM bra_list WHERE locations like '%{$search}%' $limit ");  
$textline2 = "Page <b>$pagenum</b> of <b>$last</b>";


$paginationCtrls = '';

$self = $_SERVER['PHP_SELF'];

if($last != 1){
    if ($pagenum > 1) {
        $previous = $pagenum - 1;
        $paginationCtrls .= '<a href="'.$self.'?page='.$previous.'">Previous</a>';
        for($i = $pagenum-4; $i < $pagenum; $i++){
            if($i > 0){
                $paginationCtrls .= '<a href="'.$self.'?page='.$i.'">'.$i.'</a>';
            }
        }
    }
    $paginationCtrls .= '<span class="current">'.$pagenum.'</span>';

    for($i = $pagenum+1; $i <= $last; $i++){
        $paginationCtrls .= '<a href="'.$self.'?page='.$i.'">'.$i.'</a>';
        if($i >= $pagenum+4){
            break;
        }
    }
    if ($pagenum != $last) {
        $next = $pagenum + 1;
        $paginationCtrls .= '<a href="'.$self.'?page='.$next.'">Next</a> ';
    }
}

您必须在分页链接中设置搜索字词。试试这个。

<form action="find.php" method="post">
<input name="search" type="search" autofocus><input type="submit" name="button">
</form>
<?php

include_once("config.php");


if(isset($_POST['button'])){ 
    $search=$_POST['search'];
}


$result = mysql_query(" SELECT * FROM bra_list WHERE locations like '%{$search}%' $limit "); 
$row = mysql_num_rows($result);
$page_rows = 3;
$last = ceil($row/$page_rows);

if($last < 1){
    $last = 1;
}
$pagenum = 1;

if(isset($_GET['page'])){
    $pagenum = preg_replace('#[^0-9]#', '', $_GET['page']);
}
// get search tearm from url
if(isset($_GET['search'])){ 
    $search=$_GET['search'];
}
if ($pagenum < 1) { 
    $pagenum = 1; 
} else if ($pagenum > $last) { 
    $pagenum = $last; 
}

$limit = 'LIMIT ' .($pagenum - 1) * $page_rows .',' .$page_rows;

$result = mysql_query(" SELECT * FROM bra_list WHERE locations like '%{$search}%' $limit ");  
$textline2 = "Page <b>$pagenum</b> of <b>$last</b>";


$paginationCtrls = '';

$self = $_SERVER['PHP_SELF'];
// you must have to set search tearm in pagination links
if($last != 1){
    if ($pagenum > 1) {
        $previous = $pagenum - 1;
        $paginationCtrls .= '<a href="'.$self.'?page='.$previous.'&search='.$search.'">Previous</a>';
        for($i = $pagenum-4; $i < $pagenum; $i++){
            if($i > 0){
                $paginationCtrls .= '<a href="'.$self.'?page='.$i.'&search='.$search.'">'.$i.'</a>';
            }
        }
    }
    $paginationCtrls .= '<span class="current">'.$pagenum.'</span>';

    for($i = $pagenum+1; $i <= $last; $i++){
        $paginationCtrls .= '<a href="'.$self.'?page='.$i.'&search='.$search.'">'.$i.'</a>';
        if($i >= $pagenum+4){
            break;
        }
    }
    if ($pagenum != $last) {
        $next = $pagenum + 1;
        $paginationCtrls .= '<a href="'.$self.'?page='.$next.'&search='.$search.'">Next</a> ';
    }
}

?>

<table border='1' cellpadding='10' style="border-collapse:collapse;">
<tr>
<th>id</th>
<th>name</th>
<th>address</th>
<th>phone</th>
<th>email</th>
<th>website</th>
<th>locations</th>
<th>info</th>
</tr>

<?php
while($row = mysql_fetch_array($result)){
?>

<tr>
<td><?php echo $row['id']; ?></td>
<td><?php echo $row['name']; ?></td>
<td><?php echo $row['address']; ?></td>
<td><?php echo $row['phone']; ?></td>
<td><?php echo $row['email']; ?></td>
<td><?php echo $row['website']; ?></td>
<td><?php echo $row['locations']; ?></td>
