Question

我正在尝试创建一个迷你聊天页面。我尝试提交一个带有一些文本和文件的表单，通过另一个php页面，而不是表单所在的位置。文本输入有效，但FILES []变为空白。我尝试测试错误可能是什么，但我的尝试都没有成功。任何帮助将非常感谢。 HTML：

<div class="inp">
<form id="dacform" name="chatf" method="post" enctype="multipart/form-data">
<div class="datpad">

<label id="txtcht"><h2>Title</h2></label>
<input onfocus="inputchf(this)" onblur="inputchb(this)" type="text" 
name="chat_title" />


<label><h2>Description </h2><p  style="display:inline-block;">(Max 140 
characters)</p></label>
<!--<input onfocus="inputchf(this)" onblur="inputchb(this)" type="text" 
name="chat_title" />-->
<!--<input type="textarea" name="chat_desc"/>-->
<textarea name="chat_desc" onfocus="textfoc(this)" onblur="textblur(this)">
</textarea>


<label><h2>Background Image</h2></label>
<input type="file" id="upload" class="custom-file-input" name="chat_back">

<!--<input type="submit" name="subm_chat" class="btn-style" value="Create 
Chat">-->
<div class="btn-style">Create Chat</div>
</form>
</div>
</div>
</div>

Javascript：

if($.post('chatcre.php', $('#dacform').serialize())){alert("sent");}

chatcre.php文件：
