assign multiple taxonomy terms according to certain categories. WordPress

such a position that is in the category "bar" and awaiting relecure Must also be connected to the category "foo" on the hook save_post

Sorry for my English

I see, there is a little issue with how you are calling

$cats = wp_set_post_categories( $post);

which is not in the right syntax. Please check the documentation for the function wp_set_post_categories i.e [[LINK href="http://codex.wordpress.org/Function_Reference/wp_set_post_categories"]]http://codex.wordpress.org/Function_Reference/wp_set_post_categories[[/LINK]]

As you can see, you have to do something like

wp_set_post_categories( $post_ID, $post_categories )

where for you, this code will be something like

<?php
//.....
// List of categories id numbers.
$post_categories=array(1, 2,3);
// This string is based on your single or multiple categories, I think single category ID in your case

wp_set_post_categories( $post->ID, $post_categories );

//or if you are only going to use the default category i.e with ID = 0, then
$cats = wp_set_post_categories( $post->ID);

// No second parameter above which defaults to 0
// Now we already have the categories which we stored as the post category(ies)

if($cats) { // If category(ies) saved properly

// $post_categories has the IDS for all categories that we saved above
// Now based on that, we can code something like this
// Since we have category ID(s) as passed in array above, we better use category ID(s) below in condition
// in_category which check if the current post is in a certain catgeory

if(in_category($any_category_id,$post->ID)) { // call for a term slug or id

wp_set_object_terms( $post_id, 'foo', 'post_tag' );

wp_set_object_terms( $post_id, 'bar', 'post_tag' );

}



if(in_category($any__other_category_id,$post->ID) { // call for a term slug or id

wp_set_object_terms( $post_id, 'foo', 'post_tag' );

wp_set_object_terms( $post_id, 'bar', 'post_tag' );

}

}


?>


I hope that helps. For slug based conditionals, Jurre Hanema's answer will help.

Well, this code works,
function ifk_set_default_object_terms($post_id, $post) {

if( 'test' === $post->post_type ) {// - check post_type

if( 'publish' === $post->post_status ) {// - Just publish

if(in_category('cat3', $post_id )) { // call for a term slug or id
wp_set_object_terms( $post_id, 'foo', 'post_tag' );
wp_set_object_terms( $post_id, 'bar', 'post_tag' );
}

if(in_category('cat4', $post_id )) {// call for a term slug or id
wp_set_object_terms( $post_id, 'tag2', 'post_tag' );
wp_set_object_terms( $post_id, 'bar2', 'post_tag' );
}
if(in_category( 1 , $post_id )) {
wp_set_object_terms( $post_id, NULL, 'post_tag' );
}
}
}
}
it creates a relationship only for the last<em>wp_set_object_terms</em>.
The ideal would be for me that I could put a conditional tag in each table.
$defaults = array(

'post_tag' => array( 'taco', 'banana' ),

'monkey-faces' => array( 'see-no-evil' ),

);
and used a foreach loop at the end of the function but obviously I'm not good with foreach loop.

Ps: sorry for being late

Maybe you can offer some context or the goal for this function, for a better understanding of the problem
