我可以先说我正在做一个计算课程，其中一个单元是介绍PHP并且我刚刚开始进入PHP。
此时我非常基本，我的任务是建立一个搜索页面，可以搜索不同的电影等。
我的生产页面（搜索页面）

我在搜索＆＃34; WWE

非常感谢！
答案 0 :(得分：0)
这不是答案！
尝试此查询
$query = "SELECT name, genre, date, time, adult, child, concession, pr.pband FROM production p INNER JOIN price pr ON p.pband = pr.pband WHERE name LIKE '$name'";
myresult.php
您有错误。在您的connection.php中，您已将$con定义为连接变量，但在查询中使用了$connection。
应该是
$result = mysqli_query($con, $query);
connection.php
你只需要传递变量，不要将它们放在任何东西中。它应该是
$con = mysqli_connect($host, $user, "",$db);
尝试使用查询
$query = "SELECT reference, name, genre, date, time, pband FROM production p INNER JOIN price pr ON p.pband = pr.pband WHERE name LIKE '$name'";
替换表格的
<td class='TD'>" . $row['reference'] . "</td>
<td class='TD'>" . $row['name'] . "</td>
<td class='TD'>" . $row['genre'] . "</td>
<td class='TD'>" . $row['date'] . "</td>
<td class='TD'>" . $row['time'] . "</td>
<td class='TD'>" . $row['pband'] . "</td>
</tr>";
