💡 Hint

Common Mistakes

Using a taxonomy name instead of a term slug.

Using a post field like 'author' instead of a term slug.

The 'terms' key expects the slug of the taxonomy term you want to filter by. Here, 'news' is a valid category slug.

💡 Hint

Common Mistakes

Using '=' which only matches exactly 100.

Using 'LIKE' which is for string pattern matching.

The 'compare' operator '>' filters posts where the meta value is greater than 100.

💡 Hint

Common Mistakes

Using 'category' which is a default taxonomy but not the one needed.

Using 'post_tag' which is for tags, not genres.

The taxonomy name must be 'genre' to match the taxonomy you want to query.

  'post_type' => 'movie',
  'meta_query' => [
    [
      'key' => 'rating',
      'value' => [[1], [2]],
      'compare' => 'BETWEEN',

💡 Hint

Common Mistakes

Swapping the lower and upper bounds.

Using values outside the expected rating scale.

The 'value' array sets the range for the 'BETWEEN' comparison. Here, 4 and 5 define the rating range.

    [
      'taxonomy' => '[1]',
      'field' => '[2]',
      'terms' => '[3]'
    ]
  ],
  'meta_query' => [
    [
      'key' => 'size',
      'value' => 'large',
      'compare' => '='
    ]
  ]
];
$query = new WP_Query($args);

💡 Hint

Common Mistakes

Using 'name' instead of 'slug' for the field.

Using wrong taxonomy or term names.

The taxonomy is 'color', the field type is 'slug', and the term is 'blue' to filter posts correctly.
