Introduction
The Transloadit PHP SDK provides a simple and efficient way to interact with Transloadit's file processing service in your PHP applications. With this SDK, you can easily:
- Create and manage file upload assemblies
- Use pre-defined templates for common file processing tasks
- Handle notifications and retrieve assembly statuses
- Integrate Transloadit's powerful file processing capabilities into your PHP projects
This SDK simplifies the process of working with Transloadit's REST API, allowing you to focus on building great applications without worrying about the complexities of file processing.
Install
Keep your Transloadit account's Auth Key & Secret nearby. You can check
the API credentials page for
these values.
Usage
1. Upload and resize an image from your server
This example demonstrates how you can use the SDK to create an Assembly
on your server.
It takes a sample image file, uploads it to Transloadit, and starts a
resizing job on it.
2. Create a simple end-user upload form
This example shows you how to create a simple Transloadit upload form
that redirects back to your site after the upload is done.
Once the script receives the redirect request, the current status for
this Assembly is shown using Transloadit::response()
.
Note: There is no guarantee that the Assembly has already finished
executing by the time the $response
is fetched. You should use
the notify_url
parameter for this.
3. Use Uppy for file uploads
We recommend using Uppy, our next-gen file uploader for the web, instead of the jQuery SDK. Uppy provides a more modern, flexible, and feature-rich solution for handling file uploads with Transloadit.
To integrate Uppy with your PHP backend:
-
Include Uppy in your HTML:
-
Initialize Uppy with Transloadit plugin:
- Handle the assembly status on your PHP backend:
Create a new file named transloadit_notify.php
in your project:
Make sure to replace 'https://your-site.com/transloadit_notify.php'
with the actual URL where you'll host this PHP script.
For more detailed information on using Uppy with Transloadit, please refer to our Uppy documentation.
4. Fetch the Assembly Status JSON
You can use the getAssembly
method to get the Assembly Status.
5. Create an Assembly with a Template.
This example demonstrates how you can use the SDK to create an Assembly
with Templates.
You are expected to create a Template on your Transloadit account dashboard
and add the Template ID here.
Signature Auth
Signature Authentication is done by the PHP SDK by default internally so you do not need to worry about this :)
## Example
For fully working examples take a look at [`examples/`](https://github.com/transloadit/php-sdk/tree/HEAD/examples).
## API
### $Transloadit = new Transloadit($properties = []);
Creates a new Transloadit instance and applies the given $properties.
#### $Transloadit->key = null;
The auth key of your Transloadit account.
#### $Transloadit->secret = null;
The auth secret of your Transloadit account.
#### $Transloadit->request($options = [], $execute = true);
Creates a new `TransloaditRequest` using the `$Transloadit->key` and
`$Transloadit->secret` properties.
If `$execute` is set to `true`, `$TransloaditRequest->execute()` will be
called and used as the return value.
Otherwise the new `TransloaditRequest` instance is being returned.
#### $Transloadit->createAssemblyForm($options = []);
Creates a new Transloadit assembly form including the hidden 'params' and
'signature' fields. A closing form tag is not included.
`$options` is an array of `TransloaditRequest` properties to be used.
For example: `"params"`, `"expires"`, `"endpoint"`, etc..
In addition to that, you can also pass an `"attributes"` key, which allows
you to set custom form attributes. For example:
#### $Transloadit->createAssembly($options);
Sends a new assembly request to Transloadit. This is the preferred way of
uploading files from your server.
`$options` is an array of `TransloaditRequest` properties to be used with the exception that you can
also use the `waitForCompletion` option here:
`waitForCompletion` is a boolean (default is false) to indicate whether you want to wait for the
Assembly to finish with all encoding results present before the callback is called. If
waitForCompletion is true, this SDK will poll for status updates and return when all encoding work
is done.
Check example #1 above for more information.
#### $Transloadit->getAssembly($assemblyId);
Retrieves the Assembly status json for a given Assembly ID.
#### $Transloadit->cancelAssembly($assemblyId);
Cancels an assembly that is currently executing and prevents any further encodings costing money.
This will result in `ASSEMBLY_NOT_FOUND` errors if invoked on assemblies that are not currently
executing (anymore).
#### Transloadit::response()
This static method is used to parse the notifications Transloadit sends to
your server.
There are two kinds of notifications this method handles:
- When using the `redirect_url` parameter, and Transloadit redirects
back to your site, a `$_GET['assembly_url']` query parameter gets added.
This method detects the presence of this parameter and fetches the current
assembly status from that url and returns it as a `TransloaditResponse`.
- When using the `notify_url` parameter, Transloadit sends a
`$_POST['transloadit']` parameter. This method detects this, and parses
the notification JSON into a `TransloaditResponse` object for you.
If the current request does not seem to be invoked by Transloadit, this
method returns `false`.
### $TransloaditRequest = new TransloaditRequest($properties = []);
Creates a new TransloaditRequest instance and applies the given $properties.
#### $TransloaditRequest->key = null;
The auth key of your Transloadit account.
#### $TransloaditRequest->secret = null;
The auth secret of your Transloadit account.
#### $TransloaditRequest->method = 'GET';
Inherited from `CurlRequest`. Can be used to set the type of request to be
made.
#### $TransloaditRequest->curlOptions = [];
Inherited from `CurlRequest`. Can be used to tweak cURL behavior using [any cURL option that your PHP/cURL version supports](https://www.php.net/manual/en/function.curl-setopt.php).
Here is an [example](examples/6-assembly-with-timeout.php) that illustrates
using this option to change the timeout of a request (drastically, to `1ms`, just to prove you can make the SDK abort after a time of your choosing).
The default timeouts and options depend on the cURL version on your system and can be verified by checking `phpinfo()` and the [curl_setopt](https://www.php.net/manual/en/function.curl-setopt.php) documentation.
#### $TransloaditRequest->endpoint = 'https://api2.transloadit.com';
The endpoint to send this request to.
#### $TransloaditRequest->path = null;
The url path to request.
#### $TransloaditRequest->url = null;
Inherited from `CurlRequest`. Lets you overwrite the above endpoint / path
properties with a fully custom url alltogether.
#### $TransloaditRequest->fields = [];
A list of additional fields to send along with your request. Transloadit
will include those in all assembly related notifications.
#### $TransloaditRequest->files = [];
An array of paths to local files you would like to upload. For example:
or
The first example would automatically give your file a field name of
`'file_1'` when executing the request.
#### $TransloaditRequest->params = [];
An array representing the JSON params to be send to Transloadit. You
do not have to include an `'auth'` key here, as this class handles that
for you as part of `$TransloaditRequest->prepare()`.
#### $TransloaditRequest->expires = '+2 hours';
If you have configured a '`$TransloaditRequest->secret`', this class will
automatically sign your request. The expires property lets you configure
the duration for which the signature is valid.
#### $TransloaditRequest->headers = [];
Lets you send additional headers along with your request. You should not
have to change this property.
#### $TransloaditRequest->execute()
Sends this request to Transloadit and returns a `TransloaditResponse`
instance.
### $TransloaditResponse = new TransloaditResponse($properties = []);
Creates a new TransloaditResponse instance and applies the given $properties.
#### $TransloaditResponse->data = null;
Inherited from `CurlResponse`. Contains an array of the parsed JSON
response from Transloadit.
You should generally only access this property after having checked for
errors using `$TransloaditResponse->error()`.
#### $TransloaditResponse->error();
Returns `false` or a string containing an explanation of what went wrong.
All of the following will cause an error string to be returned:
- Network issues of any kind
- The Transloadit response JSON contains an `{"error": "..."}` key
- A malformed response was received
**_Note_**: You will need to set waitForCompletion = True in the $Transloadit->createAssembly($options) function call.
