我正在尝试在我们的网站上创建一个上传，基本上我们可以添加各种大小的图像到输入，他们都去各自的目标位置。
这是表格
<form action="upload.php" method="post" enctype="multipart/form-data">
Select 120px image to upload:
<input type="file" name="img120" id="img120">
Select 125px image to upload:
<input type="file" name="img125" id="img125">
Select 600px image to upload:
<input type="file" name="img600" id="img600">
Select default image to upload:
<input type="file" name="imgdef" id="imgdef">
<input type="submit" value="Upload Images" name="submit">
</form>
这提交了一个名为upload.php的php文件，其代码如下：
// set upload target directory and filename
$img120_dir = "../wp-content/uploads/ShortTermImages/120px/";
$img120_file = $img120_dir . basename($_FILES["img120"]["name"]);
$img125_dir = "../wp-content/uploads/ShortTermImages/125px/";
$img125_file = $img125_dir . basename($_FILES["img125"]["name"]);
$img600_dir = "../wp-content/uploads/ShortTermImages/600px/";
$img600_file = $img600_dir . basename($_FILES["img600"]["name"]);
$imgdef_dir = "../wp-content/uploads/ShortTermImages/";
$imgdef_file = $imgdef_dir . basename($_FILES["imgdef"]["name"]);
// set file valid variable
$img120_uploadOk = 1;
$img125_uploadOk = 1;
$img600_uploadOk = 1;

此刻脚本无法正常运行，我无法理解为什么？
orry输出如下：
Success: File is an image - image/jpeg.
Success: File is an image - image/jpeg.

答案 0 :(得分：0)
在继续之前，您确保填充了$ target_file变量。查看代码$ target_file永远不会填充任何内容。我扔了一个任意的目录路径，我的图片正确上传。
