function themeSlug_enqueue_scripts() { wp_enqueue_style( 'themeSlug-reset', get_template_directory_uri() .'/css/reset.css', '1.0.0' ); wp_enqueue_style( 'themeSlug-style', get_template_directory_uri() .'/style.css', 'themeSlug-reset', '1.0.0'); } add_action('wp_enqueue_scripts', 'themeSl...

In this case style.css is located in root of the theme's folder function themeSlug_enqueue_scripts() { wp_enqueue_style( 'themeSlug-style', get_template_directory_uri() .'/style.css', '1.0.0'); } add_action('wp_enqueue_scripts', 'themeSlug_enqueue_scripts');

In this example we want to include font awesome icon font function themeSlug_enqueue_scripts() { wp_enqueue_style( 'font-awesome', '//cdnjs.cloudflare.com/ajax/libs/font-awesome/4.6.3/css/font-awesome.css'); } add_action('wp_enqueue_scripts', 'themeSlug_enqueue_scripts');

Writing testable code is an important part of building a robust, maintainable, and agile project. Support for PHP's most widely used testing framework, PHPUnit, is built right into Laravel.

function add(a, b) return a + b end -- creates a function called add, which returns the sum of it's two arguments Let's look at the syntax. First, we see a function keyword. Well, that's pretty descriptive. Next we see the add identifier; the name. We then see the arguments (a, b) these c...

Functions are only useful if we can call them. To call a function the following syntax is used: print("Hello, World!") We're calling the print function. Using the argument "Hello, World". As is obvious, this will print Hello, World to the output stream. The returned value is ...

Creating anonymous functions Anonymous functions are just like regular Lua functions, except they do not have a name. doThrice(function() print("Hello!") end) As you can see, the function is not assigned to any name like print or add. To create an anonymous function, all you hav...

Functions in Lua can return multiple results. For example: function triple(x) return x, x, x end When calling a function, to save these values, you must use the following syntax: local a, b, c = triple(5) Which will result in a = b = c = 5 in this case. It is also possible to ignore r...

Views, in an MVC pattern, contain the logic on how to present data to the user.

A view can be called u...

git clean -fX Will remove all ignored files from the current directory and all subdirectories. git clean -Xn Will preview all files that will be cleaned.

git clean -fd Will remove all untracked directories and the files within them. It will start at the current working directory and will iterate through all subdirectories. git clean -dn Will preview all directories that will be cleaned.

In addition to reading data with Eloquent, you can also use it to insert or update data with the save() method. If you have created a new model instance then the record will be inserted; otherwise, if you have retrieved a model from the database and set new values, it will be updated. In this exa...

You can delete data after writing it to the database. You can either delete a model instance if you have retrieved one, or specify conditions for which records to delete. To delete a model instance, retrieve it and call the delete() method: $user = User::find(1); $user->delete(); Alternat...

The padding property sets the padding space on all sides of an element. The padding area is the space between the content of the element and its border. Negative values are not allowed. You can specify a side individually: padding-top padding-right padding-bottom padding-left The following...

The padding property sets the padding space on all sides of an element. The padding area is the space between the content of the element and its border. Negative values are not allowed. To save adding padding to each side individually (using padding-top, padding-left etc) can you write it as a shor...

Implementations in classes, including abstract declarations, take precedence over all interface defaults. Abstract class method takes precedence over Interface Default Method. public interface Swim { default void backStroke() { System.out.println("Swim.backStroke"); ...

An Anaphoric Macro is a macro that introduces a variable (often IT) that captures the result of a user-supplied form. A common example is the Anaphoric If, which is like a regular IF, but also defines the variable IT to refer to the result of the test-form. (defmacro aif (test-form then-form &o...
