如何将上传文件的$ target_dir更改为绝对路径 - 网站根目录?

It's a WordPress plugin that enables uploading images. Right now, images are uploaded to: http://localhost/wp-content/2018/10/image.png. I want them to be stored in the root of the website. In the main folder where are folders like wp-content, wp-admin and other files.

Here is the code that uploads files to the destination mantioned above.

 <div class="wrap">
<h2>Upload files</h2>
<form action="" method="post" enctype="multipart/form-data">
Select file to upload (Supported files: .rar, .zip, .txt, .xml):
<input type="file" name="fileToUpload" id="fileToUpload">
<input type="submit" value="Upload Image" name="submit">
</form>
</div>
<?php
// Check if image file is a actual image or fake image
if(isset($_POST["submit"])) {
    $target_dir = wp_upload_dir();
    $target_file = $target_dir['path'] . '/' . 
basename($_FILES["fileToUpload"]["name"]);
    $uploadOk = 1;
    $imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));
    $check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
    if($check !== false) {
        echo "File is an image - " . $check["mime"] . ".";
        $uploadOk = 1;
    } else {
        echo "File is not an image.";
        $uploadOk = 0;
    }
    // Check if file already exists
    if (file_exists($target_file)) {
        echo "Sorry, file already exists.";
        $uploadOk = 0;
    }
    // Check file size
    if ($_FILES["fileToUpload"]["size"] > 500000) {
        echo "Sorry, your file is too large.";
        $uploadOk = 0;
    }
    // Allow certain file formats
    if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType 
!= 
        "jpeg"
    && $imageFileType != "gif" ) {
        echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
        $uploadOk = 0;
    }
    // Check if $uploadOk is set to 0 by an error
    if ($uploadOk == 0) {
        echo "Sorry, your file was not uploaded.";
        // if everything is ok, try to upload file
    } else {
        if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], 
$target_file)) {
            echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " 
has been 
                uploaded.";
        } else {
            echo "Sorry, there was an error uploading your file.";
        }
    }

}



}

It should be something like: /home/user/public_html/ or /Users/username/Sites/wp/ or something similar, but I don't know how to implement it.

    You need to add this function to get root path get_home_path().

    Change this line

    $target_file = $target_dir['path'] . '/' . basename($_FILES["fileToUpload"]["name"]);
    

    With below

    $target_file = get_home_path() . '/' . basename($_FILES["fileToUpload"]["name"]);
