Php Upload Not Making It to Temp Folder
Uploading files, images, and videos using PHP is as easy as adding a couple of scripts. This guide volition show yous two dissimilar ways on how to add php file upload functionality to your site:
- The Uncomplicated PHP Manner – This is the simplest way of adding a PHP uploader to your service. The upside is that you accept consummate control of the files being uploaded.
- Filestack'southward PHP File Upload Service – This is an easier way of adding PHP upload functionality. The upside is that y'all practise non accept to manage the circuitous file upload infrastructure behind-the-scenes.
Let's get started with some piece of cake examples:
PHP File Upload – The Simple Manner
To start, we'll create the following:
one. The HTML Form
Commencement, we'll create an HTML class that the user volition see when they want to upload the file. Create a new binder for this case project, and within it, create an alphabetize.html file with the following code:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-viii"> <title>PHP File Upload</championship> </head> <trunk> <form action="fileUploadScript.php" method="mail service" enctype="multipart/form-data"> Upload a File: <input blazon="file" proper noun="the_file" id="fileToUpload"> <input type="submit" name="submit" value="Start Upload"> </form> </trunk> </html> A couple important things to observe in the instance higher up:
-
action="fileUploadScript.php"– This references the PHP script that will handle the file upload on the backend -
method="post"– This tells the browser action the form will use when sending the file to the server (for uploads, this is almost e'er a Mail service activeness, sometimes a PUT) -
enctype="multipart/class-data"– This determines the content-blazon that the class submits
Next, open up your terminal and from the directory where you created the file, outset the PHP server:
And then, open your spider web browser and become to localhost:1234. You should see something like this:
2. The PHP File Upload Script
Next, we'll handle the backend of the file upload. Outset, in the same directory, create a new directory called uploads. This will be where our script volition salve the files.
And then, in the aforementioned directory as index.html, create a file called fileUploadScript.php. Notice that this is the aforementioned name as the action aspect in the form. Then add together this code:
<?php $currentDirectory = getcwd(); $uploadDirectory = "/uploads/"; $errors = []; // Shop errors here $fileExtensionsAllowed = ['jpeg','jpg','png']; // These will be the only file extensions immune $fileName = $_FILES['the_file']['proper name']; $fileSize = $_FILES['the_file']['size']; $fileTmpName = $_FILES['the_file']['tmp_name']; $fileType = $_FILES['the_file']['type']; $fileExtension = strtolower(finish(explode('.',$fileName))); $uploadPath = $currentDirectory . $uploadDirectory . basename($fileName); if (isset($_POST['submit'])) { if (! in_array($fileExtension,$fileExtensionsAllowed)) { $errors[] = "This file extension is non immune. Please upload a JPEG or PNG file"; } if ($fileSize > 4000000) { $errors[] = "File exceeds maximum size (4MB)"; } if (empty($errors)) { $didUpload = move_uploaded_file($fileTmpName, $uploadPath); if ($didUpload) { echo "The file " . basename($fileName) . " has been uploaded"; } else { echo "An error occurred. Please contact the administrator."; } } else { foreach ($errors equally $error) { repeat $error . "These are the errors" . "\north"; } } } ?> A couple things to note:
- The key used to access the file from the
$_FILESobject matches the name attribute used in the course -
$fileName = $<em>FILES['the</em>file']['name'];– 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 -
$fileExtension = strtolower(terminate(explode('.',$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, it is prepare to the current working directory
Also note that in the lawmaking higher up, we validate the file upload by checking both the file type and size. (But png and jpeg files that are less than 4MB)
Now there are a couple final steps earlier we can get-go uploading files:
- Go to your
uploads/directory and make it writable by running:chmod 0755 uploads/ - Make sure your
php.inifile is correctly configured to handle file uploads (Tip: to detect your php.ini file, runphp --ini):
max_file_uploads = 20 upload_max_filesize = 2M post_max_size = 8M Finally, if y'all now starting time the PHP server and get to localhost:1234, then upload a file, yous should see it salve in the uploads folder!
Keep in listen that the all of the lawmaking above requires additional security precautions before existence released in product. For example, there are currently no checks to run into if the user has uploaded a virus disguised every bit an image. To acquire more, check out this commodity which describes various ways to handle secure file uploads.
File Upload with Filestack
In this 2d instance, we'll use Filestack to upload a file. Filestack is an advanced file upload API and service that securely stores files in the cloud.
Why employ a third party like Filestack over building it yourself? By using a third party you no longer need to bargain with the scaling, security, and maintenance that comes with edifice your ain file upload system. This can free y'all up to focus on building other important parts of your application.
And you can get started for costless. Filestack has a free plan that handles up to 100 monthly uploads with 1GB storage and 1GB bandwidth. If you need to go beyond that amount, they offering pricing that scales with use.
So let's get started:
i. Sign up for a Filestack Account
First, nosotros'll sign up for a Filestack business relationship. Get to their registration folio and after you log in, get the API Fundamental, which y'all will use in the later steps.
two. Offset Uploading
Now that we have 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 instance, if they wanted to upload from a URL or from social media. But supercede the contents of index.html with the following:
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-viii"> <title>PHP File Upload</title> </head> <body> <style> .picker-content{ height: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 client = filestack.init(YOUR_API_KEY); let options = { "displayMode": "inline", "container": ".picker-content", "accept": [ "image/jpeg", "image/jpg", "image/png" ], "fromSources": [ "local_file_system" ], "uploadInBackground": simulated, "onUploadDone": (res) => panel.log(res), }; picker = client.picker(options); picker.open up(); }); </script> <div course="picker-content"></div> </body> </html> So, open your page and then upload a file using the upload widget. After uploading, you should exist able to log into your Filestack dashboard and see your newly uploaded file:
And that's information technology! You don't even need the server to handle the file, which is better for scalability, security, and maintenance.
Filestack PHP Library (optional)
The in a higher place case covers the simplest example of uploading a file with Filestack. But, what if you wanted to access the file on your server to run some kind of mail-processing, like checking if an paradigm is rubber for work? To practice that, you can utilize the Filestack PHP library. Nosotros'll use Composer to install the Filestack PHP library. If you don't take Composer already, y'all can install information technology by going to the folder you lot created originally and running (see 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'); } echo PHP_EOL;" php composer-setup.php php -r "unlink('composer-setup.php');" Afterward y'all do the above, you should be able to encounter Composer's output past running php composer.phar.
Then run require --prefer-dist filestack/filestack-php to install the Filestack SDK.
Now that we have the Filestack library, allow'south brand a new PHP script to check if a specific uploaded file is safe for work. Create a new file called fileUploadFilestack.php and add the post-obit (making sure to change the YOUR_API_KEY, YOUR_SECURITY_SECRET, and YOUR_FILE_HANDLE variables):
<?php require __DIR__ . '/vendor/autoload.php'; apply Filestack\FilestackClient; $client = new FilestackClient(YOUR_API_KEY); $security = new FilestackSecurity(YOUR_SECURITY_SECRET); $file_handle = YOUR_FILE_HANDLE; # become tags with customer $result_json = $customer->getTags($file_handle); # become tags with filelink $filelink = new Filelink($file_handle, YOUR_API_KEY, $security); $json_result = $filelink->getTags(); # get safe for work flag with filelink $json_result = $filelink->getSafeForWork(); ?> When this script is run, the result of the safe-for-work check volition be saved in the $json_result variable. And that's 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
