Handling File Attachments in PHP with Mailgun Form Submission

Hey everyone, I’m struggling with a PHP issue. I’m trying to figure out how to grab and store file attachments that come through a form submission using Mailgun’s POST method.

Here’s what I’m dealing with:

$attachmentInfo = [
    'file1' => [
        'name' => 'funny_cat.jpg',
        'type' => 'image/jpeg',
        'tmp_name' => '/tmp/php123abc',
        'size' => 54321
    ],
    'file2' => [
        'name' => 'notes.txt',
        'type' => 'text/plain',
        'tmp_name' => '/tmp/php456def',
        'size' => 1234
    ]
];

$contentType = 'multipart/form-data; boundary=---------------------------12345678901234';

I can see the attachment info, but I’m not sure how to actually save these files on my server. Any help would be awesome! Thanks in advance.

hey dave, i’ve dealt w/ this before. u can use move_uploaded_file() to save the files. here’s a quick example:

foreach ($attachmentInfo as $file) {
    $newPath = '/your/upload/dir/' . $file['name'];
    move_uploaded_file($file['tmp_name'], $newPath);
}

just make sure ur upload dir is writable. also, watch out for security stuff like checking file types n sizes.

Having worked extensively with file uploads in PHP, I can offer some insights. The key is using move_uploaded_file() function, but there’s more to consider. Ensure you validate file types and sizes before processing. A robust approach includes generating unique filenames to prevent overwrites. Here’s a snippet to illustrate:

$uploadDir = '/secure/upload/path/';
foreach ($attachmentInfo as $file) {
    $ext = pathinfo($file['name'], PATHINFO_EXTENSION);
    $newFileName = uniqid() . '.' . $ext;
    $newFilePath = $uploadDir . $newFileName;
    if (move_uploaded_file($file['tmp_name'], $newFilePath)) {
        // Store $newFilePath in database
    } else {
        // Log error
    }
}

This method ensures unique filenames and maintains the original extension. Remember to implement proper error handling and logging for production environments.

I’ve dealt with a similar situation before when working on a file upload system for a client’s website. Here’s what worked for me:

First, you’ll want to use the move_uploaded_file() function to move the temporary files to a permanent location on your server. Something like this:

$uploadDir = '/path/to/your/upload/directory/';

foreach ($attachmentInfo as $file) {
    $newFilePath = $uploadDir . $file['name'];
    if (move_uploaded_file($file['tmp_name'], $newFilePath)) {
        // File moved successfully
        // You might want to store the new file path in a database here
    } else {
        // Handle error
    }
}

Make sure your upload directory has the correct permissions set. Also, it’s crucial to validate and sanitize the file names to prevent security issues.

Remember to handle potential errors, like exceeding file size limits or uploading forbidden file types. You might want to implement additional checks based on your specific requirements.

Hope this helps you get started!
