[edit] Purpose

This extension provides 'looping' functionality (e.g. 'foreach') for iterating through arrays.

[edit] Feature

• Security: only pages with protection on 'edit' can use the keywords provided by this extension

[edit] Usage

[edit] Simple Array

• {{#foreachx:global object name|property|pattern}}
  • The global object's property will be retrieved; the property should be an 'array'
• {{#foreachx:global object name|method|pattern}}
  • The global object's method will be called: an array is expected as return value
• {{#foreachx:global array variable|key|pattern}}
  • The global array variable will be referenced using 'key' as key
• {{#foreachx:global array variable||pattern}}
  • The global array variable will be referenced (as a whole)
• {{#foreachx:class name|static property|pattern}}
  • The static property of class name will be referenced (as a whole)

[edit] Simple Array with Conditional

• {{#foreachc: X | Y |pattern|match value|match value replacement}} where {X:Y} can be:
  • { Global Object Name: Property }
  • { Global Object Name: Method }
  • { Global Array Variable: Key }
  • { Class Name: Static Property }

'match value' is represented by $match$ in the pattern field. When the 'value' of the current array entry matches the 'match' variable provided, then $match$ is replaced with 'match value'.

[edit] Array of Arrays

• {{#foreachy:global object name|property|pattern}}
  • The global object's property will be retrieved; the property should be an 'array'
• {{#foreachy:global object name|method|pattern}}
  • The global object's method will be called: an array is expected as return value
• {{#foreachy:global array variable|key|pattern}}
  • The global array variable will be referenced using 'key' as key
• {{#foreachy:global array variable||pattern}}
  • The global array variable will be referenced (as a whole)

[edit] Dependancies

• Extension:StubManager
• Extension:ParserPhase2 extension

[edit] Notes

[edit] Other Extensions From the same author

Consult User Jldupont's page.

1. ↑ The most recent release is always available through the extension's PEAR and SVN repositories. This page is not necessarily up-to-date.
2. ↑ ^{2.0 2.1 2.2} Extension:ExtensionManager does not require any modification to LocalSettings.php because ExtensionManager includes the extension.
   Note that if PHP code caching is in place (e.g. APC, eAccelerator), then to successfully complete the installation a cache flush might be needed.
3. ↑ Modifications to LocalSettings.php is only necessary if not using Extension:ExtensionManager
