[RFC] hook assign_block_vars

[topdown]

• Name: hook_assign_block_vars
• Rationale: This hook will allow someone to filter/add to a specified assign_block_vars allowing addition of vars in a specific loop.
• Placement: includes/template.php
• Input arguments: $block_name, $vararray = array(), $args = array()
• Output format: array
• Output semantics: Returns the array for $block_name
• Infrastructure: This would allow hooking into any templates block_vars array with ease and without editing core files or other mods.

I might miss something, but this sounds like template::alter_block_array. I'm not sure what advantage this hook will bring over alter_block_array.

[nickvergessen]

With the hook you don't need to edit the core, else you need to edit the core and add your alter statement somewhere.

I believe a better approach would be to hook the arrays before they enter that function. You have a better understanding of what data is going in, and you don't need to detect what's going into assign_block_vars

Consider the following... (viewtopic.php code ref: Check sticky/announcement time limit)

Simplified version, assume core code:

Code: Select all

if ($topic_data['topic_type'] == POST_STICKY)
{
	... some code including an sql query ...
} 

A mod edit would result in:

Code: Select all

if ($topic_data['topic_type'] == POST_STICKY || $topic_data['topic_type'] == MOD_VAR)
{
	... somecode including an sql query ...
}

How would this be handled with hooks?
