Hi im not really understanding this part of code to display the portfolio page
<?php
$args = array(
'post_type' => 'portfolio'
);
$the_query = new WP_Query( $args );
?>
<?php if ( have_posts() ): while ( $the_query->have_posts() ): $the_query->the_post(); ?>
I know that $args is an array but now the key and the value of that array is what im not understanding. why 'post_type' and why 'portfolio' is portfolio a specific id set to the portfolio field we created or is it just a random variable?
and what is $the_query = new WP Query ( $args );
exactly?
I understand how the loop works and all but just not what it's passing on top such as the_query.

There are many arguments that you can pass to WP Query:

19,315 PointsJust a couple questions because im not fully understanding,
Where do I set the post type to portfolio, in the admin area under the custom fields section?
What is
the_query
? a pre set value of some sort or just a random variableAnd if im understanding correct
WP_Query
is a wordpress class that displays different parameters??Andrew McCormick

17,730 PointsWhere do I set the post type to portfolio if you are following the video you set it using the 'Custom Post Type' plugin.
What is the_query? yes. it's just a variable name that makes sense. you could use any valid variable name here.
And if im understanding correct WP_Query is a wordpress class that displays different parameters?? It defines your loop. From the codex: WP_Query is a class defined in wp-includes/query.php that deals with the intricacies of a posts (or pages) request to a WordPress blog. The wp-blog-header.php (or the WP class in Version 2.0) gives the $wp_query object information defining the current request, and then $wp_query determines what type of query it's dealing with (possibly a category archive, dated archive, feed, or search), and fetches the requested posts. It retains a lot of information on the request, which can be pulled at a later date. If you already understand the Loop then take some time to read the codex on [WP Query}(http://codex.wordpress.org/Class_Reference/WP_Query) next.
