Hook at the start of file

[Deep Blue 76]

I've created a custom static method in \IPS\Member:

	static function hello()
	{
		$hello = "something";
		
		return $hello;
	}

Now I need to retrieve it in a template:

{{$hello = \IPS\Member::hello();}}

but forums/topicRow template, where I'm working, start with a foreach and I can't hook before it to assign passing $hello.

I've found a dirty workaround but what is the best way to do it?

You need to create a theme hook on the template and add the code in the beginning. So you'd set up a theme hook on forums -> front -> forums. Add one to topicRow.

Your selector will be li.ipsDataItem

Then you can insert php code before the selector. Something like

{{expression="\IPS\Member::hello();"}}

There are no selector to hook in this template before the foreach

<ips:template parameters="$table, $headers, $rows" />
{{$rowIds = array();}}
{{foreach $rows as $row}}
	{{$idField = $row::$databaseColumnId;}}
	{{$rowIds[] = $row->$idField;}}
{{endforeach}}
{{if \count( $rows )}}
	{{$rowCount=0;}}
	{{foreach $rows as $row}}
		{{if $rowCount == 1 AND $advertisement = \IPS\core\Advertisement::loadByLocation( 'ad_forum_listing' )}}
			<li class="ipsDataItem">
				{$advertisement|raw}
			</li>
		{{endif}}
		{{$rowCount++;}}
		{{$idField = $row::$databaseColumnId;}}
		{{if $row->mapped('moved_to')}}
			{{if $movedTo = $row->movedTo() AND $movedTo->container()->can('view')}}
				<li class="ipsDataItem">

If I've a query inside my hello() then if I hook on li.ipsDataItem I've
1 query x num topics

If I'm understanding you correctly, you want to hook in to the topicRow template before the foreach loop, is that right?

Create a theme hook on the appropriate template file, and this will create a plugin file in your plugin directory with nothing but a hookData() method in it. This plugin file extends the template code, so you can then manually define the topicRow template and call the parent like so

//<?php

/* To prevent PHP errors (extending class does not exist) revealing path */
if ( !\defined( '\IPS\SUITE_UNIQUE_KEY' ) )
{
	exit;
}

class hook347 extends _HOOK_CLASS_
{

/* !Hook Data - DO NOT REMOVE */
public static function hookData() {
 return array_merge_recursive( array (), parent::hookData() );
}
/* End Hook Data */


public function topicRow( $table, $headers, $rows )
{
	// Do whatever you need to do here

	return parent::topicRow( $table, $headers, $rows );
}

}
