多个 PHP 上传，每个文件具有不同的目标位置

我正在尝试在我们的网站上创建一个上传，基本上我们可以将各种尺寸的图像添加到输入中，它们都转到各自的目标位置。

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>

这将提交到一个名为 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;
    $imgdef_uploadOk = 1;
// set file type
    $img120_FileType = pathinfo($img120_file,PATHINFO_EXTENSION);
    $img125_FileType = pathinfo($img125_file,PATHINFO_EXTENSION);
    $img600_FileType = pathinfo($img600_file,PATHINFO_EXTENSION);
    $imgdef_FileType = pathinfo($imgdef_file,PATHINFO_EXTENSION);

// CHECK IF IMAGE IS AN ACTUAL IMAGE FILE   

    // Check 120px image      
    if(isset($_POST["submit"])) {
        $check = getimagesize($_FILES["img120"]["tmp_name"]);
        if($check !== false) {

            $img120_uploadOk = 1;
        } else {
