我想导航页面显示列表中的所有元素,并且当您选择某些内容时仅显示相关元素。请帮忙解决这个问题。

1 个答案:

答案 0 :(得分:0)

如果你没有使用Javascript - 因为你还没有发布JS代码..

您需要将HTML中的详细信息发送到PHP页面。

例如,您的select标签没有'name'来标识它到PHP POST页面..

所以你需要这样的东西:

       <select id="type" name="type_id" multiple> ....

该名称然后通知php您将值发送到$ _POST ['type_id'];

修复HTML以符合PHP的期望应解决您的问题..

编辑:(更多信息) HTML需要将您想要的信息和值发送到PHP代码,以便PHP可以使用它。如果您使用.ajax将数据发送到PHP但您的HTML未命名..

你的php $ _POST ['NAME_OF_INPUT'];

来自HTML'name'标签..例如:

<?php
if(isset($_POST['testName']))
echo "You entered : ".$_POST['testName'];

&GT;

<form action="" method="POST">
<input name="testName" type="text"/>
<button>Submit</button>
