converting from query_posts

Need to change my code from query_posts to use get_posts

Why?

From WordPress codex:

https://codex.www.ads-software.com/Function_Reference/query_posts

Note: This function isn’t meant to be used by plugins or themes. As explained later, there are better, more performant options to alter the main query. Double Note: query_posts() is overly simplistic and problematic way to modify main query of a page by replacing it with new instance of the query.

consider to change the code to WP_Query() – which has a much closer relationship to query_posts() than get_posts();
https://codex.www.ads-software.com/Class_Reference/WP_Query

if using get_posts() don’t forget to include setup_postada( $post ) – https://codex.www.ads-software.com/Template_Tags/get_posts

also watch that 'category_name' uses the category slug (NOT name); https://codex.www.ads-software.com/Class_Reference/WP_Query#Category_Parameters

have you tried using the pre_get_posts() filter?

Thanks for the pointers.

How do I get an array out of the loop using WP_Query?

Take this from the WordPress functions page, how do I put get_the_title() into an array, amongst other things?

$the_query = new WP_Query( $args );

// The Loop
while ( $the_query->have_posts() ) {
	$the_query->the_post();
	echo '<li>' . get_the_title() . '</li>';
}

With this, I get Undefined variable title on line…

$the_query = new WP_Query( $args );

// The Loop
while ( $the_query->have_posts() ) {
	$the_query->the_post();
	$title[] = get_the_title();
}

I just echo $title[0] or $title[1] for example.
