    <p>This should be easy for a PHP expert. I am having trouble storing and pulling arrays in Wordpress through the update_user_meta function.</p> <p>So I have an associative array built like so:</p> <pre>Array ( [film_genres] => Array ( [action] => 50 [comedy] => 50 [crime] => 50 [documentary] => 50 [drama] => 50 [family] => 50 [horror] => 50 [romantic] => 50 [sci-fi] => 50 [thriller] => 50 ) [film_types] => Array ( [blockbuster] => 0 [independent] => 0 ) [film_eras] => Array ( [1920s_1940s] => 0 [1950s_1960s] => 0 [1970s_1980s] => 0 [1990s_2000s] => 0 [post_2010] => 0 [pre_1920s] => 0 ) [last_updated] => 2011-10-12 21:21:28 )</pre> <p>But when I go to update this data in the user meta table via:</p> <p><strong>update_user_meta( $user_id, $meta_key, $meta_value, $prev_value )</strong></p> <p>The data gets put in the db properly, but when i call the data back and print the new array to screen, it has a nested array key of [0] within the array, like this:</p> <pre> Array ( [0] => Array ( [film_genres] => Array ( [action] => 50 [comedy] => 50 [crime] => 50 [documentary] => 50 [drama] => 50 [family] => 50 [horror] => 50 [romantic] => 50 [sci-fi] => 50 [thriller] => 50 ) [film_types] => Array ( [blockbuster] => 0 [independent] => 0 ) [film_eras] => Array ( [1920s_1940s] => 0 [1950s_1960s] => 0 [1970s_1980s] => 0 [1990s_2000s] => 0 [post_2010] => 0 [pre_1920s] => 0 ) [last_updated] => 2011-10-12 21:21:28 ) ) </pre> <p>How can I get it to store the array exactly like my first array? I am pulling the meta value array via the WP command: </p> <p><code>$wp_user_film_prefs_arr = get_user_meta( $wp_user_id, $wp_user_film_prefs_key_label, false );</code></p> <p>Is there something I'm doing wrong? Thanks in advance!!!</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
