Developing software in the Real World
Zend Framework is renaming to Laminas and all the source code is moving to a new GitHub organisation. Implicitly this means a new PHP top level namespace. As you can imagine, this implies that a lot of our code will need to change, so Matthew, Michał and the team have been writing migration tooling to make this easier. It's now time to test it and they need all the help they can get on real-world… continue reading.
This site uses WordPress under the hood as I find the flexibility that a good CMS provides quite useful. For the talks section, I use a custom post type so that I can set additional properties on the post and customise the display. With my usual lack of imagination, my custom post type is called talk. When Notist was released, I've been uploading the PDFs for my presentations there so that I have a nicely… continue reading.
When writing blog posts, I write directly in HTML, mostly from habit and because I've not set up mark-up text processing on WordPress. I'm comfortable enough with simple HTML that it's never seemed important enough to sort out, especially with MarsEdit's macros for common HTML tags. One thing that I need to do relatively regularly is to HTML encode code snippets for use in <tt> and <pre> tags. I have been doing this via a… continue reading.
One of the nice things about Slim 4 is that it's easier to customise the HTML generated on error without having to worry about the rest of the error handling mechanism. This is because we have separated error rendering from error handling. Slim's default ErrorHandler maintains a list of renderers, one for each content-type and will delegate the creation of the error payload (HTML, JSON, XML, etc) to the renderer. Out of the Box, the… continue reading.
I've recently moved to Adobe Lightroom Classic for photo editing, but am still using Apple Photos for viewing my photos on my iPhone and iPad. As such, I wanted an easy way to import photos exported from Lightroom into Photos, so I turned to AppleScript. My requirements are that I want to import all the photos in each sub-folder of a root folder called "ToPhotos" into Folders and Albums in Photos that are a child… continue reading.
In contrast with Slim 2 and Slim 3, Slim 4 does not ship with a DI container, but instead, supports any PSR-11 compatibly DI container that you provide. This is part of Slim 4's commitment to interoperability via the PHP-FIG standards. The easiest way to add a container to your Slim application is to call AppFactory::setContainer() before you call AppFactory::create(). The setContainer() method expects any PSR-11 container. Register the container with Slim Let's look at… continue reading.
If you want to run Slim 4 in a subdirectory of your website, then you have a few things you need to do. Let's consider the situation: Your main website is in the directory /var/www/html and is accessed at https://example.com/. You want your new Slim 4 app to be in the directory /var/www/html/myapp and to be accessed at https://example.com/myapp. Your Slim 4 index.php file is stored in /var/www/html/myapp. There are two things you need to… continue reading.
To simplify creating a new Slim 4 project, I've created slim4-empty which does this for me. To use it:
|
1 |
$ composer create-project akrabat/slim4-empty my-new-project |
and you're done! The my-new-project directory is created and contains Slim 4 along with a minimally viable public/index.php to get you going. You can then run it with the PHP built-in server:
|
1 |
php -S 0.0.0.0:8888 -t public/ |
And navigate to https://localhost:8888 to view "Hello World" in your browser. What does it contain? Slim4-empty provides no structure to your project… continue reading.
A Slim 4 (and Slim 3) application receives data from three places: Any query parameters on the URL (the key-value pairs after the ?) The HTTP message's body (usually for POST and PUT) messages Parameters in the URL (such as the 3 in https://example.com/users/3 Within the application, these are available within the PSR-7 Request object. Let's start with a simple Slim 4 application. Firstly we require the Slim framework and a PSR-7 implementation:
|
1 |
$ composer require slim/slim slim/psr7 |
Now… continue reading.
I have so many photos that I can't store them all on my hard drive and keep them on my NAS. While on my home network, it would be convenient to automatically mount the NAS folder onto my Mac as I keep forgetting before I open Lightroom. Usually I would use automount to do this, but Lightroom cannot see automounted folders, so I decided to use a combination of AppleScript and Keyboard Maestro. Mount a… continue reading.
