Using PHP for file-upload in Wordpress

I'm trying to upload files from the front end of a wordpress page to send to the back-end wordpress directory within wp-content. I can't figure out why files are not appearing in the back end folder 'uploads' which is what the $target_dir is set as. Here is my HTML form on one page. 

<form action="http://www.aeroex.co.uk/php-upload/" method="post" enctype="multipart/form-data">
Select image to upload:
<input type="file" name="fileToUpload" id="fileToUpload">
<input type="submit" value="Upload Image" name="submit">
</form>

The form action page for the above form, www.aeroex.co.uk/php-upload/ , contains the following PHP code: 

<?php
$target_dir = "http://www.aeroex.co.uk/home3/dy/public_html/wp-content/uploads";
$target_file = $target_dir . basename($_FILES["fileToUpload"]["name"]);
$uploadOk = 1;
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
// Check if image file is a actual image or fake image
if(isset($_POST["submit"])) {
$check = getimagesize($_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;
}
}
?>

A recommended approach is to use wp_handle_upload() function. You can use it with wp_insert_attachment() if you wanted to add files to media library.

The first function wp_handle_upload() does:

Handle PHP uploads in WordPress, sanitizing file names, checking extensions for mime type, and moving the file to the appropriate directory within the uploads directory.

An example from WordPress site with some changes

if ( ! function_exists( 'wp_handle_upload' ) ) {
    require_once ABSPATH . 'wp-admin/includes/file.php';
}

$uploadedfile = $_FILES['file'];

/* You can use wp_check_filetype() function to check the
 file type and go on wit the upload or stop it.*/

$movefile = wp_handle_upload( $uploadedfile);

if ( $movefile && !isset( $movefile['error'] ) ) {
    echo "File is valid, and was successfully uploaded.\n";
    var_dump( $movefile);
} else {
    /**
     * Error generated by _wp_handle_upload()
     * @see _wp_handle_upload() in wp-admin/includes/file.php
     */
    echo $movefile['error'];
}

Alternatively you could just use wp_upload_dir() to get only the upload dir.

If you want to upload a file to the library and attach it to a post you can use the Wordpress function media_handle_upload()

$attachment_id = media_handle_upload( 'your_file_field_name', $post_id);

See example

pathinfo() expects a path not a URL.

$target_dir should be a path, eg: /home3/dy/public_html/wp-content/uploads. Check $_SERVER['DOCUMENT_ROOT'] if you are not sure.

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

Then, you've got a path where you want the files to be uploaded to. Now you need to run:

move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file);
