Question

我使用wordpress中的表单上传文件，我想打印上传的文件的名称但是我得到空的结果。

以下是我的代码

HTML

<form id="myform" action="" method="post" enctype='multipart/form-data'>
<span style="margin-right:20px;">SELECT THE CATEGORY:</span>
<select name="category" id="category" style="background-color:brown;color:#ffffff;">
    <option value="" disabled="disabled" selected="selected">Please select a competition category</option>
    <option value="Cutie Pie">Cutie Pie</option>
    <option value="Chubby">Chubby</option>
    <option value="Dimples">Dimples</option>
</select>   <br><br>
 <input type="file" name="file" style="margin-top:12px;">
    <br><br>

<input name="upload" type="submit" value="klk"/>
</form>
<div id="result"></div>

php代码我用来获取和打印文件名

$file=$_FILES['file'];
 $name = $file['name'];
echo basename($name);

但是我得到空洞的结果......请帮忙

首先你需要正确接收文件，然后就可以得到它的名字：

档案up.php

$uploaddir = './upload/'; //give this dir write permissions
$uploadfile = $uploaddir . basename($_FILES['uploadFile']['name']);

if (move_uploaded_file($_FILES['uploadFile']['tmp_name'], $uploadfile)) {
    //now you can get the filename
    $file = basename($uploadfile);
    echo "<div id='result'>File <b>$file</b> is valid, and was successfully uploaded.</div>";

} else {
echo <<< LOB
    <form id="myform" action="up.php" method="post" enctype='multipart/form-data'>
    <span style="margin-right:20px;">SELECT THE CATEGORY:</span>
    <select name="category" id="category" style="background-color:brown;color:#ffffff;">
    <option value="" disabled="disabled" selected="selected">Please select a competition category</option>
    <option value="Cutie Pie">Cutie Pie</option>
    <option value="Chubby">Chubby</option>
    <option value="Dimples">Dimples</option>
    </select>   <br><br>
    <input type="file" name="uploadFile" style="margin-top:12px;">
    <br><br>
    <input name="upload" type="submit" value="klk"/>
    </form>
LOB;
}

这只是一个简短的示例，您应该改进此代码，方法是验证文件扩展名是否正确，这样您就不会获得php个文件上传到您的服务器......

在php中返回上传的文件名
