Constructor & Destructor Documentation

◆ __construct()

ResourceLoaderImageModule::__construct ( array  $options = [],
  $localBasePath = null 
)

Constructs a new module from an options array.

Parameters
array$optionsList of options; if not given or empty, an empty module will be constructed
string | null$localBasePathBase path to prepend to all local paths in $options. Defaults to $IP

Below is a description for the $options array:

Construction options:
[
// Base path to prepend to all local paths in $options. Defaults to $IP
'localBasePath' => [base path],
// Path to JSON file that contains any of the settings below
'data' => [file path string]
// CSS class prefix to use in all style rules
'prefix' => [CSS class prefix],
// Alternatively: Format of CSS selector to use in all style rules
'selector' => [CSS selector template, variables: {prefix} {name} {variant}],
// Alternatively: When using variants
'selectorWithoutVariant' => [CSS selector template, variables: {prefix} {name}],
'selectorWithVariant' => [CSS selector template, variables: {prefix} {name} {variant}],
// List of variants that may be used for the image files
'variants' => [
// This level of nesting can be omitted if you use the same images for every skin
[skin name (or 'default')] => [
[variant name] => [
'color' => [color string, e.g. '#ffff00'],
'global' => [boolean, if true, this variant is available
for all images of this type],
],
...
],
...
],
// List of image files and their options
'images' => [
// This level of nesting can be omitted if you use the same images for every skin
[skin name (or 'default')] => [
[icon name] => [
'file' => [file path string or array whose values are file path strings
and whose keys are 'default', 'ltr', 'rtl', a single
language code like 'en', or a list of language codes like
'en,de,ar'],
'variants' => [array of variant name strings, variants
available for this image],
],
...
],
