How to Upload a Product Adding Script to My Website
Uploading files, images, and videos using PHP is equally easy as adding a couple of scripts. This guide will show you 2 different ways on how to add together php file upload functionality to your site:
- The Simple PHP Mode – This is the simplest style of adding a PHP uploader to your service. The upside is that you have consummate control of the files being uploaded.
- Filestack's PHP File Upload Service – This is an easier manner of calculation PHP upload functionality. The upside is that you practice not accept to manage the complex file upload infrastructure backside-the-scenes.
Let'due south get started with some like shooting fish in a barrel examples:
PHP File Upload – The Simple Way
To start, nosotros'll create the following:
1. The HTML Grade
Starting time, we'll create an HTML course that the user will see when they want to upload the file. Create a new binder for this example projection, and inside it, create an index.html file with the following code:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-eight"> <championship>PHP File Upload</title> </head> <torso> <form action="fileUploadScript.php" method="postal service" enctype="multipart/grade-data"> Upload a File: <input type="file" proper noun="the_file" id="fileToUpload"> <input blazon="submit" name="submit" value="Start Upload"> </course> </body> </html> A couple important things to notice in the instance above:
-
action="fileUploadScript.php"– This references the PHP script that will handle the file upload on the backend -
method="mail"– This tells the browser action the form will use when sending the file to the server (for uploads, this is near always a POST action, sometimes a PUT) -
enctype="multipart/course-data"– This determines the content-type that the form submits
Next, open your terminal and from the directory where you lot created the file, start the PHP server:
Then, open up your web browser and go to localhost:1234. Yous should see something like this:
2. The PHP File Upload Script
Next, nosotros'll handle the backend of the file upload. First, in the same directory, create a new directory called uploads. This will be where our script volition save the files.
And then, in the aforementioned directory every bit index.html, create a file called fileUploadScript.php. Discover that this is the same proper name as the activeness attribute in the grade. Then add together this code:
<?php $currentDirectory = getcwd(); $uploadDirectory = "/uploads/"; $errors = []; // Shop errors hither $fileExtensionsAllowed = ['jpeg','jpg','png']; // These will be the only file extensions allowed $fileName = $_FILES['the_file']['proper noun']; $fileSize = $_FILES['the_file']['size']; $fileTmpName = $_FILES['the_file']['tmp_name']; $fileType = $_FILES['the_file']['blazon']; $fileExtension = strtolower(terminate(explode('.',$fileName))); $uploadPath = $currentDirectory . $uploadDirectory . basename($fileName); if (isset($_POST['submit'])) { if (! in_array($fileExtension,$fileExtensionsAllowed)) { $errors[] = "This file extension is non allowed. Please upload a JPEG or PNG file"; } if ($fileSize > 4000000) { $errors[] = "File exceeds maximum size (4MB)"; } if (empty($errors)) { $didUpload = move_uploaded_file($fileTmpName, $uploadPath); if ($didUpload) { echo "The file " . basename($fileName) . " has been uploaded"; } else { echo "An error occurred. Please contact the ambassador."; } } else { foreach ($errors as $mistake) { echo $error . "These are the errors" . "\north"; } } } ?> A couple things to note:
- The key used to access the file from the
$_FILESobject matches the name aspect used in the form -
$fileName = $<em>FILES['the</em>file']['proper noun'];– This is the name of the actual file -
$fileSize = $<em>FILES['the</em>file']['size'];– This is the size of the file in bytes -
$fileTmpName = $<em>FILES['the</em>file']['tmp_name'];– This is the a temporary file that resides in thetmpdirectory of the server -
$fileExtension = strtolower(finish(explode('.',$fileName)));– This gets the file extension from the file name -
$uploadPath = $currentDir . $uploadDirectory . basename($fileName);– This is where the files will be stored on the server. In the script above, information technology is set up to the electric current working directory
Also note that in the code above, we validate the file upload by checking both the file type and size. (Only png and jpeg files that are less than 4MB)
At present in that location are a couple terminal steps earlier we tin can showtime uploading files:
- Go to your
uploads/directory and brand it writable by running:chmod 0755 uploads/ - Make sure your
php.inifile is correctly configured to handle file uploads (Tip: to find your php.ini file, runphp --ini):
max_file_uploads = 20 upload_max_filesize = 2M post_max_size = 8M Finally, if you now starting time the PHP server and go to localhost:1234, then upload a file, y'all should see information technology salvage in the uploads folder!
Continue in listen that the all of the code to a higher place requires additional security precautions earlier being released in product. For example, in that location are currently no checks to see if the user has uploaded a virus disguised as an image. To learn more, check out this article which describes diverse ways to handle secure file uploads.
File Upload with Filestack
In this second instance, we'll apply Filestack to upload a file. Filestack is an avant-garde file upload API and service that securely stores files in the cloud.
Why utilize a third party like Filestack over edifice it yourself? By using a third party you no longer need to deal with the scaling, security, and maintenance that comes with building your own file upload organisation. This tin can free y'all up to focus on building other important parts of your application.
And yous can go started for gratis. Filestack has a free plan that handles up to 100 monthly uploads with 1GB storage and 1GB bandwidth. If you lot demand to get beyond that corporeality, they offer pricing that scales with employ.
So permit's get started:
1. Sign up for a Filestack Account
Start, we'll sign upward for a Filestack business relationship. Become to their registration folio and later on you log in, go the API Key, which you will use in the later on steps.
2. First Uploading
Now that we accept the Filestack library, let's integrate their JavaScript file uploader widget, which allows your users to connect to a variety of other sources from which to upload from. For case, if they wanted to upload from a URL or from social media. Just replace the contents of index.html with the post-obit:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <championship>PHP File Upload</title> </head> <body> <style> .picker-content{ acme:300px; width:200px; } </style> <script src="//static.filestackapi.com/filestack-js/2.x.x/filestack.min.js"></script> <script blazon="text/javascript"> document.addEventListener("DOMContentLoaded", function(event) { const customer = filestack.init(YOUR_API_KEY); let options = { "displayMode": "inline", "container": ".picker-content", "take": [ "image/jpeg", "image/jpg", "image/png" ], "fromSources": [ "local_file_system" ], "uploadInBackground": false, "onUploadDone": (res) => console.log(res), }; picker = client.picker(options); picker.open(); }); </script> <div class="picker-content"></div> </torso> </html> Then, open your page and then upload a file using the upload widget. After uploading, you should be able to log into your Filestack dashboard and run across your newly uploaded file:
And that's it! You don't even need the server to handle the file, which is better for scalability, security, and maintenance.
Filestack PHP Library (optional)
The higher up case covers the simplest example of uploading a file with Filestack. Simply, what if you wanted to access the file on your server to run some kind of postal service-processing, like checking if an image is safe for piece of work? To do that, y'all tin apply the Filestack PHP library. Nosotros'll use Composer to install the Filestack PHP library. If you don't take Composer already, you lot can install it by going to the folder you created originally and running (come across this for official documentation):
php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');" php -r "if (hash_file('sha384', 'composer-setup.php') === '48e3236262b34d30969dca3c37281b3b4bbe3221bda826ac6a9a62d6444cdb0dcd0615698a5cbe587c3f0fe57a54d8f5') { echo 'Installer verified'; } else { repeat 'Installer corrupt'; unlink('composer-setup.php'); } repeat PHP_EOL;" php composer-setup.php php -r "unlink('composer-setup.php');" After you practice the above, you should exist able to see Composer'southward output past running php composer.phar.
Then run require --adopt-dist filestack/filestack-php to install the Filestack SDK.
Now that nosotros take the Filestack library, let'south make a new PHP script to bank check if a specific uploaded file is rubber for work. Create a new file called fileUploadFilestack.php and add the following (making sure to change the YOUR_API_KEY, YOUR_SECURITY_SECRET, and YOUR_FILE_HANDLE variables):
<?php require __DIR__ . '/vendor/autoload.php'; use Filestack\FilestackClient; $client = new FilestackClient(YOUR_API_KEY); $security = new FilestackSecurity(YOUR_SECURITY_SECRET); $file_handle = YOUR_FILE_HANDLE; # go tags with client $result_json = $client->getTags($file_handle); # become tags with filelink $filelink = new Filelink($file_handle, YOUR_API_KEY, $security); $json_result = $filelink->getTags(); # become safe for work flag with filelink $json_result = $filelink->getSafeForWork(); ?> When this script is run, the result of the safe-for-work bank check will be saved in the $json_result variable. And that'southward just one example. Using the Filestack PHP SDK allows you to perform a multifariousness of tasks on your uploaded files. Check out these other examples:
- Transform a file before upload
- Exam if a file upload is "safety for work"
- Transcode uploaded video or audio
- Catechumen a file upload to pdf
- And more than…
