File upload (images, pdfs) from base64 value

[Raymond Geerts]

I'm working on a XML RPC api to communicate between WoodWing Enterprise and a ProcessWire site.

One of the method calls i'm building is pw.uploadPWFile which has to upload files, it does this by posting a XML RPC call to this method sending the following parameters as payload:

• Page ID
• Username
• Password
• Data
  • Filename
  • MIME Type
  • Bits (base64)

I could not find any example on how to upload a file from base64 binary posted data, and how to assign this file to a field.

Are there any examples available or can sombody point me in the right direction?

Save the base64 data as decoded file to a temporary place (e.g. /assets/cache/) and then just add it to the file field and it will be copied to the correct path.

@LostKobrakai thanks for the tip. Martijn also mentioned this method.

To be sure the temp file gets removed properly after a certain amount of time, i will use the WireTempDir class to create a tmp folder which will be removed automaticly after a X amount of time.

Create the file (from base64) in there with fwrite and assign the file path of the tmp file to my image field.

$tmpDir = new WireTempDir('someName');
// add files
$fileBasename = 'basename.ext';
$filename = $tmpDir->get() . $fileBasename;
file_put_contents($filename, base64_decode($b64Data));
$page->files->add($filename);
// repeat for all files ...

// optionally, at the end call
$tmpDir->removeAll();

EDIT: Ah, you already know / found WireTempdir()

EDIT2: If one use WireTempDir for very timeconsuming tasks, one optionally can define a maxAge for it, different than the default 120 seconds:

$tmpDir = new WireTempDir('someName', array('maxAge' => 300));

@Horst... wow....

[Raymond Geerts]

@Horst thanks for the working example. Saves me from typing

[horst]

@Horst... wow....

I found wireTempDir myself a few days ago, so memory fingerprint was fresh.

[Martijn Geerts]

Found it via pw3.0 (in seperate class) Looked for it in 2.7 and mentioned to Raymond.

[Raymond Geerts]

Note:

$tmpDir = wireTempDir('someName');

Should be:

$tmpDir = new WireTempDir('someName');

[horst]

Thanks Raymond. Have updated it in the code example above.

[bernhard]

there are still some wrong wireTempDir that shoud be WireTempDir

[LostKobrakai]

Actually php isn't case sensitive in terms of class names, therefore both should work. But still WireTempDir feels to be less prone to errors coming up.

[bernhard]

ok maybe thats related to tracydebugger?

Ah. It's probably because of the namespacing in PW 3.0 http://code.runnable.com/Vtcay97VO6lCfjAD/case-sensitive-class-test-for-php

Edit: OK, strangely the published snippet doesn't throw. So I'm not sure about it.
