WOOF_Collection :: item_class( Integer $i, Arguments $args = array() )

Returns:

  • String The class attribute and value, if the item is the first or last item in the collection, or an empty string otherwise.

A useful method to add ‘class=”first”‘ or ‘class=”last”‘ (or other classes as specified in $args) to HTML tags as you loop through the collection, without needing to track this yourself. Using this requires a fairly specific loop code-pattern, specifically the index needs to be exposed in the foreach loop with the => syntax – please see the example.

Example:

Parameters:

  • Integer $i

    The index of the item in the list, which mast be passed from a loop variable that tracks it (see example).

  • Arguments $args = array()

    An arguments array or string with the following params:
    * first: the class to apply to the first item – default “first”
    * last: the class to apply to the last item – default “last”

MasterPress 1.4.0 is now available

6th May 2024

This release has a focus on improving compatibility with PHP 8.2. The introduction of inheritance validation to PHP produced a lot of warnings when using MasterPress with PHP 8.2. I have updated most of the problematic code – but some code would have broken in previous PHP versions, so I have temporarily disabled inheritance validation… 

Plugin Requirements

MasterPress requires a minimum of WordPress version 4.9, MySQL 5.6, and PHP version 5.6.20.

We also recommend that PHP is configured to use a memory limit of 64MB per request (128MB may be required for sites with higher complexity).

This plug-in is not compatible with the WordPress.com hosted service.
