PHP upload a file to selected subdirectory

Question

I have a form that will upload to the directory it is in, but I need it to upload to subdirectories or subdirectories of subdirectories from a select. But unsure how to use the select info.

My folder structure is 4 layers of folders

Produce
Produce/Meat
Produce/Meat/Beef
Produce/Meat/Beef/Portions
Produce/Meat/Beef/Packaged
Produce/Vegtables
Produce/Vegetables/Fresh
Produce/Vegetables/Fresh/Local etc,.

This is my form

<form id="Upload" action="upload_file.php" method="post" enctype="multipart/form-data">
<br>
        <label for="fileSelect"><strong>There is a 10MB limit Filesize limit.</strong> Allowed file types are pictures, MSWord, MSExcel, PDF, and plain text. Navigate and choose:</label>
        <input type="file" name="file" id="fileSelect"><br><br>
        Upload to:
        <select name="folder"><option value="this" selected>This folder</option><option value="BBB">Meat</option><option value="CCC">Meat/Beef</option><option value="DDD">Meat/Beef/Portions</option><option value="EEE">Meat/Beef/Packaged</option><option value="FFF">Vegetables</option><option value="GGG">Vegetables/Fresh</option><option value="HHH">Vegetables/Fresh/Local</option><option value="III">Vegetables/Fresh/Packaged</option></select>
        <input class="button" type="submit" name="action" value="Upload to Shared Folder"><br><br>
    </form>

Then the upload_file.php has this PHP code

<?php

if(isset($_FILES["file"]["error"])){
    if($_FILES["file"]["error"] > 0){
        echo "Error: " . $_FILES["file"]["error"] . "<br>";
    } else{
        $allowed = array("jpg" => "image/jpg", "jpeg" => "image/jpeg", "gif" => "image/gif", "png" => "image/png", "doc" => "application/msword", "docx" => "application/vnd.openxmlformats-officedocument.wordprocessingml.document", "xls" => "application/vnd.ms-excel", "xlsx" => "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet", "pdf" => "application/pdf", "txt" => "text/plain");
        $filename = $_FILES["file"]["name"];
        $filetype = $_FILES["file"]["type"];
        $filesize = $_FILES["file"]["size"];

        // Verify file extension
        $ext = pathinfo($filename, PATHINFO_EXTENSION);
        if(!array_key_exists($ext, $allowed)) die("Error: This file is not an accepted file type.</br></br>");

        // Verify file size - 10MB maximum
        $maxsize = 200000 * 60;
        if($filesize > $maxsize) die("Error: File size is larger than the allowed 10MB limit.</br></br>");

        // Verify MYME type of the file
        if(in_array($filetype, $allowed)){
            // Check whether file exists before uploading it
            if(file_exists("general/" . $_FILES["file"]["name"])){
                echo $_FILES["file"]["name"] . " already exists. Go back and choose another file or rename the original.</br></br>";
            } else{
                move_uploaded_file($_FILES["file"]["tmp_name"], "" . $_FILES["file"]["name"]);
                echo "The file was uploaded successfully.</br></br>";
            } 
        } 
        else{
            echo "Error: There was a problem uploading the file - please try again."; 
        }
    }
} else{
    echo "Error: Invalid parameters - something is very wrong with this upload.";
}
?>

Is there a way I can take the select value and upload to the subdirectory selected?

Answer 1

There are plenty of ways to do this, so here's one way:

Check to see if the POST array is set (for the dropdown select), then inside check to see if it is equal to a value from the options, then move your file inside the chosen folder:

if(isset($_POST['folder'])){

    if($_POST['folder'] == 'this'){

    // move_uploaded_file to said folder

    }

    if($_POST['folder'] == 'BBB'){

    // move_uploaded_file to said folder

    }

    // ... do the same for the others below


}

you can also set a default upload folder.

Note: Look for my original snippet inside // My snippet START --- // My snippet END.

<?php

if(isset($_FILES["file"]["error"])){
    if($_FILES["file"]["error"] > 0){
        echo "Error: " . $_FILES["file"]["error"] . "<br>";
    } else{
        $allowed = array("jpg" => "image/jpg", "jpeg" => "image/jpeg", "gif" => "image/gif", "png" => "image/png", "doc" => "application/msword", "docx" => "application/vnd.openxmlformats-officedocument.wordprocessingml.document", "xls" => "application/vnd.ms-excel", "xlsx" => "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet", "pdf" => "application/pdf", "txt" => "text/plain");
        $filename = $_FILES["file"]["name"];
        $filetype = $_FILES["file"]["type"];
        $filesize = $_FILES["file"]["size"];

        // Verify file extension
        $ext = pathinfo($filename, PATHINFO_EXTENSION);
        if(!array_key_exists($ext, $allowed)) die("Error: This file is not an accepted file type.</br></br>");

        // Verify file size - 10MB maximum
        $maxsize = 200000 * 60;
        if($filesize > $maxsize) die("Error: File size is larger than the allowed 10MB limit.</br></br>");

        // Verify MYME type of the file
        if(in_array($filetype, $allowed)){
            // Check whether file exists before uploading it
            if(file_exists("general/" . $_FILES["file"]["name"])){
                echo $_FILES["file"]["name"] . " already exists. Go back and choose another file or rename the original.</br></br>";
            } else{

        if($_POST['folder'] == 'this'){

        $uploaddir = '/var/www/uploads/Produce/';

        }
