我正在尝试从html，PHP中解决问题。前端模板很聪明。
当我在复选框中执行var_dump($_POST)某些值时显示null值`
但是当我使用var_dump($_REQUEST)时，它正确显示。
表单设置为method=post。
此外如果我从浏览器复制整个html并在我的localhost上检查它，var_dump($_POST)正在正确显示值。
那么在使用$_POST时，错误的原因可能是什么原因导致错误？
文件update_profile.tpl的内容如下：

答案 0 :(得分：0)
首先，使用循环在select中生成选项，例如：
{foreach from=$arrNetworkDTO item=NetworkDTO}
<option value="{$NetworkDTO->name|escape}">{$NetworkDTO->name}</option>
{/foreach}
关于null值，有人也有这个问题：Checkbox array returning NULL
