javascript - 以同样的形式上传图片和文字

Question

当我通过单独的形式上传图像和文本时，效果很好。但当我加在一起时它不起作用。 我的表单文本通过js上传，图像通过php文件上传。 我认为我的问题出在我的形式上。

如果我和js一起上传，我的js和submit.php有什么变化，也在下面添加。

这是我的表单代码，不能一起工作

<form action="" method="post" id="cmntfrm" enctype="multipart/form-data">
<fieldset id="cmntfs">
<legend class="pyct">
What's your mind
</legend>
<input type="hidden" name="username" size="22" tabindex="1" id="author" value="'.$pname.'"/>
<input type="hidden" name="email" size="22" tabindex="2" id="email" value="'.$email.'"/>
<p><textarea name="comment" rows="10" tabindex="4" id="comment"></textarea></p>


<div id="ajaxuploadfrm">
<form action="uploadpostimg.php" method="post" enctype="multipart/form-data">
<b>Select an image (Maximum 1mb)</b>
<input type="file" name="url" id="url" />
</form>
</div>

<p><input type="submit" name="submit" value="Post comment" tabindex="5" id="submit"/></span></p>
</fieldset>             
<input type="hidden" name="parent_id" id="parent_id" value="0" />
<input type="hidden" name="tutid2" id="tutid" value="'.$tutid2.'" />
</form>

点击提交后，您可以将代码放入js中，您必须在js文件中进行更改

$.post('phpapgename.php',data:jquerydata,function(){
})

在 .php 页面中，您可以输入查询来提交数据。
