Php HTML文件输入不工作
我正在制作一个社交媒体网站，用于课堂的最后一个项目。在这个页面中，我试图允许用户插入和图像到墙上的帖子。我有html表单的代码，该表单包含在文件中，当它独立运行时，它可以完美地工作，但是当我尝试将其放入代码中时，php中的$\u FILES数组总是空的。我已经确定php.ini文件中的max post size和max input size足够大，但是我真的不知道还有什么可以做，在这一点上，我尝试了stackoverflow的每一篇文章中的每个建议。这是我的输入表格Php HTML文件输入不工作,php,html,Php,Html,我正在制作一个社交媒体网站，用于课堂的最后一个项目。在这个页面中，我试图允许用户插入和图像到墙上的帖子。我有html表单的代码，该表单包含在文件中，当它独立运行时，它可以完美地工作，但是当我尝试将其放入代码中时，php中的$\u FILES数组总是空的。我已经确定php.ini文件中的max post size和max input size足够大，但是我真的不知道还有什么可以做，在这一点上，我尝试了stackoverflow的每一篇文章中的每个建议。这是我的输入表格 <form metho

您的标记中没有操作？
你可以试试这个
<form method="post" enctype="multipart/form-data" action="your_action.php">
//your form
</form>
//你的表格
那里有很多与问题无关的代码。你能把这个问题减到最小限度吗？看到你正在把表格发送到你的PHP
页面了吗？对不起，我不知道你的意思。您是否询问表单是否将数据发送到另一个php文件进行处理？如果这就是你的意思，那么表单没有action或onsubmit函数。action
属性不是严格要求的。如果省略了它，则表单将发布到当前URL，除非另有覆盖。看见
<form method="post" enctype="multipart/form-data" action="your_action.php">
//your form
</form>
