WordPress wp_insert_post没有插入标签

Question

I am trying to insert a post with this code:

$my_post = array(
                'post_type'    => "essays",
                'post_title'    => 'TEST 3',
                //'post_content'  => $content,
                'post_status'   => 'draft',
                'post_author'   => 1,
                //'post_category' => $cat,
                'tags_input'    => 'TQM,tag',
        );

$post_id = wp_insert_post($my_post);

Everythings works ok except the tags, it does not insert any of them. Any idea?

Answer 1

Use the wp_set_object_terms() function:

http://codex.wordpress.org/Function_Reference/wp_set_object_terms

wp_set_object_terms($post_id , $arrayoftags, $name_of_tag_taxonomy, false);

Good luck

Answer 2

Your post type is essays . Custom post types do not support tags by default. You'll have to add a tags taxonomy to them.

http://codex.wordpress.org/Taxonomies

Answer 3

To insert the post with tags and categories do this

$pid=wp_insert_post($new_post);
wp_set_post_terms( $pid, $arrayoftags);
wp_set_post_categories( $pid, $arrayofcategories );

so $pid is the post id basically you first insert the post without tags or categories and the function returns the post's id which you can then use to insert the tags and categories each with their respective function, if you look at the source code of wp_insert_post you will notice that the function works in a different way for custom post types, I did not look more into it as I don't want to hack the code as there is a better solution by using the built in functions

Hi I found this answer somewhere and this might help you out

//first get the term (I used slug, but  you can aslo use 'name'), see: http://codex.wordpress.org/Function_Reference/get_term_by
$term = get_term_by( 'slug', 'your custom term slug', 'your custom taxonomy' );
//then get the term_id
$term_id = $term->term_id;
//Use 'tax_input' instead of 'post_category' and provide the term_id:
'tax_input' => array( 'your taxonomy' => $term_id )

Hope that helps.

Answer 5

tags and post categories ought to be entered as an array, even if it's only one. So 'tags_input' => 'TQM,tag' should be 'tags_input' => array('TQM,tag')
