I've JUST started using WordPress..i'm trying to add posts to Wordpress using php and i came across this piece of code:

// Create post object
$my_post = array(
  'post_title'    => 'My post',
  'post_content'  => 'This is my post.',
  'post_status'   => 'publish',
  'post_author'   => 1,
  'post_category' => array(8,39)
);

// Insert the post into the database
wp_insert_post( $my_post );

i understand this is the way to go when creating a post using php..my questions are:

  1. how do we execute the above php script and where do we save it in the WordPress folder?

  2. what does the 'post_category' array mean(i'd like to use a category id to add posts to WordPress)?

i'd like to mention that i've done some descent searching on the net but the resources i've found do not mention how to execute the above script.

Check the docs at http://codex.wordpress.org/Function_Reference/wp_insert_post for the parameters to use with wp_insert_post

This function inserts posts (and pages) in the database. It sanitizes variables, does some checks, fills in missing variables like date/time, etc. It takes an array as its argument and returns the post ID of the created post (or 0 if there is an error).

You run your function once in the context of a plugin, or worst case, in functions.php or in index.php and then remove it.

  • Why is it bad to run, etc. in functions.php all the time? I mean why it is better to run in some custom plugin with a file also something like functions.php (plugin)? – user385917 Jul 30 '17 at 9:45
  • functions.php is run on each page load by the site, so if you run code to add posts, you will end up errors or warnings that the post(s) already exist(s), or it will add the same post(s) each page load. Run as a plugin once by activating the plugin, and then deactivate the plugin and you get only one execution of the insert posts. – markratledge Jul 30 '17 at 15:31
