文件上传不起作用

Question

I've made a contact form with an option to upload image. It's in WordPress(my form is a part of a custom plugin I'm making).

Everytime I upload a file, I find $_FILE to be empty.

Here's code of my form.

<table>
<tr>
    <td valign="top">
        <form action="" method="post" enctype="multipart/form-data">            
        <table cellspacing="0" cellpadding="0" bordercolor="#000000" border="0" bgcolor="#ffffff" width="100%">
            <tbody>
                <tr>
                    <td width="100%">
                        <table cellspacing="0" cellpadding="2" border="0" width="100%">
                            <tbody>
                            <tr>
                                <td width="50%" height="35" >Your Name:<span >*</span></td>
                                <td width="50%"><font size="2" face="Arial" color="#000000">
                                    <input type="text" size="20" value="" id="name" name="formAppName"></font>
                                </td>
                            </tr>
                            <tr>
                                <td height="35" >Your Web Address:<span >*</span></td>
                                <td><font size="2" face="Arial" color="#000000">
                                    <input type="text"  size="20" value="" id="webAddress" name="webAddress"></font>
                                </td>
                            </tr>
                            <tr>
                                <td height="35" >E-mail Address:<span >*</span></td>
                                <td><input type="text" size="20" value="" id="email" name="email"></td>
                            </tr>
                            <tr>

Answer 1

作为参考，它是$ _FILES，而不是$ _FILE。

Answer 2

First of all, action is missing from your form (it's empty). Also, you need to post what you have done in your PHP script.
