Uploading Files With wp_remote_post Or wp_remote_request — July 30, 2014

Uploading Files With wp_remote_post Or wp_remote_request

My job at WooThemes enables me to work on all sorts of cool projects and enables me to push the limits of what is possible with¬†WordPress each day. Some of the projects I work on that I enjoy the most is projects that involves interfacing with any sort of API service, I am a sucker for an API ūüôā

In a recent project which involved interfacing with an API service I had to upload a file to the service, and wanting to stay true to the WordPress way I naturally built the whole API interface layer using native WordPress functionality. This involved making use of the wp_remote_request function, which is called by the wrapper function wp_remote_post to send through POST requests.

After Googling for quite a while I just could not get any examples of uploading files in binary using wp_remote_post or wp_remote_request, for that matter, which resulted in me having to figure this out on my own.

The API document was straight forward, in order to upload a file you need to post it as binary to API endpoint, now there are plenty of example of doing this using cURL, so I used that as a starting point and converted it to WordPress native functionality.

The cURL way of uploading the file

Digging through some cURL docs I found that I basically needed to set a header to binary, and then stream the file binary content as the body, and found the following way of uploading the file using either wp_remote_request or wp_remote_post

The above code shows examples of using either wp_remote_request or wp_remote_post, as you can see there is not much difference between the two, instead that with wp_remote_post there is no need to set the method header as it is a wrapper function that does that automatically.

In some cases API services will require you to do uploads with PUT requests instead of POST, in that case you will use the wp_remote_request function and just set the method header to PUT instead of POST to make a PUT request.

Hope this helps someone out there that has also struggled to do this using native WordPress functions.




Controlling WordPress Auto Updates — October 25, 2013

Controlling WordPress Auto Updates

WordPress 3.7 was just released and one major feature that it includes is the ability have WordPress automatically updated to new versions without you having to log in and click a button.

I think it is absolutely great feature and can save you so much time in having to not log into all your site and clicking buttons, however it may not to appeal to everyone.

Reliability wise the auto update feature has been tested to death in beta and release candidates and the team working on this has ensured to cover all failure points to ensure that should something go wrong it will roll back to your previous version of WordPress. Even after 25000 auto updates in the RC releases there was not one single failure.

The WordPress team has catered for controlling auto updates via an array of filters and constants, the main constant being WP_AUTO_UPDATE_CORE. With the WP_AUTO_UPDATE_CORE constant you can control to allow disabling of auto updates, only allowing minor updates to occur automatically or allowing all updates to be done automatically.

The code below shows you how to control the automatic updates for different scenarios, you will place the code in your wp-config.php file.

If you want more control of specific features such as allowing auto updates of development releases such as beta and alpha releases, or want to only enable just major or just minor updates you can do that with the use of some filters. The following code shows examples of how to control specific WordPress auto update features, this code needs to be placed in your theme’s functions.php file.

WordCamp Cape Town 2013

At the beginning of the year our team at WooThemes HQ down here in Cape Town decided to approach previous organisers of the WordCamp Cape Town event to hear what their plans was for this year and if they would be willing to give over reigns of the event to us. Without any hassle or negativity from their side they agreed and we immediately set out to start promoting WordPress in South Africa more.

We started the WPCapeTown site, which is our main site and body under which we promote WordPress. The thing to note here is that even though it is a Cape Town community it is not limited to Cape Town and we welcome any WordPress user/creator from all over South Africa.
