php - php 中的可点击结果

Question

尝试显示可点击的结果。

<form method="post" action="AF9.php">
            <input type="submit" name="submit" value=" search ">
            <input type="text" name="search" />
</form>

这里是 AF9.php 文件的一部分:

<?php

        $connection = @new mysqli(HOSTNAME, MYSQLUSER, MYSQLPASS, MYSQLDB);
        if ($connection->connect_error) {
         die('Connect Error: ' . $connection->connect_error);
        }
        else {

        $search=$_POST["search"];

        $query="SELECT *,  FROM comments AS c JOIN namestable2 AS w ON c.w1 = w.w1
        WHERE name like '%$search%' 
        ORDER BY name DESC";                         
        $connection->query("SET NAMES utf8");               
        $result_obj = '';
        $result_obj = $connection->query($query);             

        while($result = $result_obj->fetch_array(MYSQLI_ASSOC)) {   
        $items[] = $result;
        }                               

        foreach ($items as $item) {
        echo('<a href="AF9.php?search='.$item['word'].'">'.$item['word'].'</a>');

}?>

但是，当我单击结果时，它显示“未定义索引:搜索”。请帮忙

以“?key=value”结尾的硬编码链接(如“?search=xyz”)将通过 GET 流传递，而不是 POST。尝试改变这个:

$search=$_POST["search"];

对此:

$search=$_GET["search"];
