我的搜索框似乎出了点问题。目前,我只查看数据库中的所有项目,也想查看我要搜索的项目。
这样吗?
<div class="searchbox">
<form action="Search.php" method="get">
<fieldset>
<input id="search" placeholder="Search for a Product" type="text" />
<input id="submit" type="hidden" />
</fieldset>
</form>
</div>
<div id="content">
<ul>
<?php
$host = "xxx";
$user = "xxx";
$pass = "xxx";
$db = "xxx";
mysql_connect($host, $user, $pass);
mysql_select_db($db);
unset($host,$user,$pass,$db);
$search = $_POST['search'];
$query = "SELECT produkt FROM checklist WHERE id LIKE '%".$_POST['search']."%'";
//$query = "SELECT produkt FROM checklist WHERE id LIKE '%$search%'";
$result = mysql_query($query);
最佳答案
<input id="$search" placeholder
您需要这里的
$
吗?它应该变成:<input id="search" placeholder
要从搜索查询内部访问GET变量,请使用$ _GET数组,如下所示:
$query = "SELECT produkt FROM checklist WHERE id LIKE '%{$_GET['search']}%'";
但是为了安全起见,避免mysql注入,您可能想要这样做:
$search = mysql_real_escape_string($_GET['search']);
$query = "SELECT produkt FROM checklist WHERE id LIKE '%{$search}%'";
编辑:在输入中忘记名称属性:
<input name="search" id="search" placeholder="Search for a Product" type="text" />
然后在你的PHP
$search = mysql_real_escape_string($_GET['search']);
$query = "SELECT produkt FROM checklist WHERE id LIKE '%{$search}%'";
$result = mysql_query($query);
while ($row = mysql_fetch_array($result)){
echo "<li><span class='name'><b>{$row['produkt']}</b></span></li>";
}
