💡 Hint

Common Mistakes

Using 'post' instead of 'product' will fetch blog posts, not products.

Leaving 'post_type' empty fetches default posts.

The 'post_type' argument specifies which type of posts to retrieve. Using 'product' fetches only product posts.

💡 Hint

Common Mistakes

Using 'title' orders alphabetically, not by date.

Using 'author' orders by who wrote the post.

Ordering by 'date' sorts posts by their publish date. 'DESC' means newest first.

💡 Hint

Common Mistakes

Using quotes makes the ID a string, which causes the query to fail.

Using 'category' instead of the ID is incorrect.

The 'cat' parameter expects an integer ID, so 5 without quotes is correct.

Fill both blanks to retrieve posts with meta key 'price' greater than 100.

Wordpress

<?php
$args = array(
  'meta_key' => '[1]',
  'meta_value' => 100,
  'meta_compare' => '[2]'
);
$query = new WP_Query($args);
?>

💡 Hint

Common Mistakes

Using '<' will get values less than 100, which is wrong here.

Using wrong meta key names will return no results.

'meta_key' specifies the custom field name, and 'meta_compare' with '>' filters values greater than 100.

Fill all three blanks to retrieve published 'event' posts ordered by title ascending.

Wordpress

<?php
$args = array(
  'post_type' => '[1]',
  'post_status' => '[2]',
  'orderby' => '[3]',
  'order' => 'ASC'
);
$query = new WP_Query($args);
?>

💡 Hint

Common Mistakes

Using 'draft' status will not show published posts.

Ordering by anything other than 'title' changes the sort order.

'post_type' set to 'event' fetches event posts, 'post_status' 'publish' gets only published posts, and ordering by 'title' sorts alphabetically.
