Comeposso ottenereilgenitore diprimo livello di un datotermine?

Sto utilizzando wp_get_object_termsper ottenerei termini dellatassonomia suipost,mainvece dimostraretuttii termini contrassegnati,desideromostrare soloi genitori diprimo livello deitermini contrassegnati.

Quindi,se questi sonoi termini selezionati,desidero visualizzare solo Colazione,pranzoe cena.

x BREAKFAST x Cereal x Eggs LUNCH Hamburger x Pizza DINNER Fish Bass x Salmon Trout Lasagna

Comepossofarlo?
How would I get the top-level parent of a given term?

I am using wp_get_object_terms to get taxonomy terms on posts, but instead of showing all tagged terms, I only want to show tagged terms' top-level parents.

So if these are my selected terms, I only want to show Breakfast, Lunch and Dinner.

x BREAKFAST x Cereal x Eggs LUNCH Hamburger x Pizza DINNER Fish Bass x Salmon Trout Lasagna

How can I do this?

Dalla 3.1.0,è disponibile get_ancestors() .Restituisce un array di antenati dalpiùbasso alpiù altonellagerarchia.

Since 3.1.0, get_ancestors() is available. It returns an array of ancestors from lowest to highest in the hierarchy.

Ecco una semplicefunzione cheti daràilprimoterminepiùgenitore di un datotermine:

function get_term_top_most_parent( $term_id, $taxonomy ) { $parent = get_term_by( 'id', $term_id, $taxonomy ); while ( $parent->parent != 0 ){ $parent = get_term_by( 'id', $parent->parent, $taxonomy ); } return $parent; }

Una volta ottenuta questafunzione,puoi semplicemente scorrerei risultati restituiti da wp_get_object_terms:

$terms = wp_get_object_terms( $post->ID, 'taxonomy' ); $top_parent_terms = array(); foreach ( $terms as $term ) { //Get top level parent $top_parent = get_term_top_most_parent( $term->ID, 'taxomony' ); //Check if you have it in your array to only add it once if ( !in_array( $top_parent->ID, $top_parent_terms ) ) { $top_parent_terms[] = $top_parent; } }
Here is a simple function that will get you the top most parent term of any given term:

function get_term_top_most_parent( $term_id, $taxonomy ) { $parent = get_term_by( 'id', $term_id, $taxonomy ); while ( $parent->parent != 0 ){ $parent = get_term_by( 'id', $parent->parent, $taxonomy ); } return $parent; }

Once you have this function you can just loop over the results returned by wp_get_object_terms:

$terms = wp_get_object_terms( $post->ID, 'taxonomy' ); $top_parent_terms = array(); foreach ( $terms as $term ) { //Get top level parent $top_parent = get_term_top_most_parent( $term->ID, 'taxomony' ); //Check if you have it in your array to only add it once if ( !in_array( $top_parent->ID, $top_parent_terms ) ) { $top_parent_terms[] = $top_parent; } }
- Grazie!Lo stoprovando adesso.Cordiali saluti,penso cheti manchi unaparentesi strettanella riga 1 dellafunzione.
  
  Thanks! I'm trying this now. FYI I think you're missing a close paren in line 1 of the function.

Ho avuto lo stessoproblemae l'ho risoltofacilmente. Controlla questo:

Definisci $taxonomy. Puòessere lo slug dellatassonomia di cui vuoi ottenerei dati. Dopo averlofatto,puoi semplicementefarlo:

 <?php
    $postterms = wp_get_post_terms($post->ID, $taxonomy);   // get post terms
    $parentId = $postterms[0]->parent;                      // get parent term ID
    $parentObj = get_term_by('id', $parentId, $taxonomy);   // get parent object 
?>

Ora hai qualcosa delgenere:

 object(stdClass)#98 (11) {
  ["term_id"]=>
  int(3)
  ["name"]=>
  string(8) "Esportes"
  ["slug"]=>
  string(8) "esportes"
  ["term_group"]=>
  int(0)
  ["term_taxonomy_id"]=>
  int(3)
  ["taxonomy"]=>
  string(17) "noticiaseditorias"
  ["description"]=>
  string(0) ""
  ["parent"]=>
  int(0)
  ["count"]=>
  int(4)
  ["object_id"]=>
  int(123)
  ["filter"]=>
  string(3) "raw"
}

Epuoi usare $parentObjper ottenere slug,nome,id,qualunque cosa. Semplicemente utilizzando $parentObj->slug o $parentObj->name comeesempio.

I had the same problem and I solved easily. Check this out:

Define $taxonomy. It can be the slug of the taxonomy you want to get the data. After doing this, you can simply do this:

<?php
    $postterms = wp_get_post_terms($post->ID, $taxonomy);   // get post terms
    $parentId = $postterms[0]->parent;                      // get parent term ID
    $parentObj = get_term_by('id', $parentId, $taxonomy);   // get parent object 
?>

Now you got something like this:

object(stdClass)#98 (11) {
  ["term_id"]=>
  int(3)
  ["name"]=>
  string(8) "Esportes"
  ["slug"]=>
  string(8) "esportes"
  ["term_group"]=>
  int(0)
  ["term_taxonomy_id"]=>
  int(3)
  ["taxonomy"]=>
  string(17) "noticiaseditorias"
  ["description"]=>
  string(0) ""
  ["parent"]=>
  int(0)
  ["count"]=>
  int(4)
  ["object_id"]=>
  int(123)
  ["filter"]=>
  string(3) "raw"
}

And you can use $parentObj to get slug, name, id, whatever. Just by using $parentObj->slug or $parentObj->name as exemple.

Ilmodopiù semplice:

 $rootId = end( get_ancestors( $term_id, 'my_taxonomy' ) );
$root = get_term( $rootId, 'my_taxonomy' );
echo $root->name;

Easiest way:

$rootId = end( get_ancestors( $term_id, 'my_taxonomy' ) );
$root = get_term( $rootId, 'my_taxonomy' );
echo $root->name;

Forse questo aiuta: get_ancestors( $object_id, $object_type );

Maybe this helps: get_ancestors( $object_id, $object_type );

Grazie a Ivayloper questo codice,basato sulla risposta di Bainternet.

Laprimafunzione di seguito,get_term_top_most_parent,accetta unterminee unatassonomiae restituisceilgenitore diprimo livello deltermine (oiltermine stesso,se è senzagenitori); la secondafunzione (get_top_parents)funzionanel cicloe,data unatassonomia,restituisce unelenco HTML deigenitori diprimo livello deitermini di unpost.

 // Determine the top-most parent of a term
function get_term_top_most_parent( $term, $taxonomy ) {
    // Start from the current term
    $parent  = get_term( $term, $taxonomy );
    // Climb up the hierarchy until we reach a term with parent = '0'
    while ( $parent->parent != '0' ) {
        $term_id = $parent->parent;
        $parent  = get_term( $term_id, $taxonomy);
    }
    return $parent;
}

Una volta che hai lafunzione sopra,puoi scorrerei risultati restituiti da wp_get_object_termse visualizzareilgenitoreprincipale di ognitermine:

 function get_top_parents( $taxonomy ) {
    // get terms for current post
    $terms = wp_get_object_terms( get_the_ID(), $taxonomy );
    $top_parent_terms = array();

    foreach ( $terms as $term ) {
        //get top level parent
        $top_parent = get_term_top_most_parent( $term, $taxonomy );
        //check if you have it in your array to only add it once
        if ( !in_array( $top_parent, $top_parent_terms ) ) {
            $top_parent_terms[] = $top_parent;
        }
    }

    // build output (the HTML is up to you)
    $output = '<ul>';
    foreach ( $top_parent_terms as $term ) {
          //Add every term
          $output .= '<li><a href="'. get_term_link( $term ) . '">' . $term->name . '</a></li>';
    }
    $output .= '</ul>';

    return $output;
}

Thanks to Ivaylo for this code, which was based on Bainternet's answer.

The first function below, get_term_top_most_parent, accepts a term and taxonomy and returns the the term's top-level parent (or the term itself, if it's parentless); the second function (get_top_parents) works in the loop, and, given a taxonomy, returns an HTML list of the top-level parents of a post's terms.

// Determine the top-most parent of a term
function get_term_top_most_parent( $term, $taxonomy ) {
    // Start from the current term
    $parent  = get_term( $term, $taxonomy );
    // Climb up the hierarchy until we reach a term with parent = '0'
    while ( $parent->parent != '0' ) {
        $term_id = $parent->parent;
        $parent  = get_term( $term_id, $taxonomy);
    }
    return $parent;
}

Once you have the function above, you can loop over the results returned by wp_get_object_terms and display each term's top parent:

function get_top_parents( $taxonomy ) {
    // get terms for current post
    $terms = wp_get_object_terms( get_the_ID(), $taxonomy );
    $top_parent_terms = array();

    foreach ( $terms as $term ) {
        //get top level parent
        $top_parent = get_term_top_most_parent( $term, $taxonomy );
        //check if you have it in your array to only add it once
        if ( !in_array( $top_parent, $top_parent_terms ) ) {
            $top_parent_terms[] = $top_parent;
        }
    }

    // build output (the HTML is up to you)
    $output = '<ul>';
    foreach ( $top_parent_terms as $term ) {
          //Add every term
          $output .= '<li><a href="'. get_term_link( $term ) . '">' . $term->name . '</a></li>';
    }
    $output .= '</ul>';

    return $output;
}

Mipiacerebbe vedere unamodifica chenon stampi soloi termini diprimo livelloma,piuttosto,tuttii termini al di sotto delgenitorepiùin alto,gerarchicamente.

I'd love to see a modification that wouldn't just print out the top-level terms but, rather, all terms beneath the top-most parent, hierarchically.

@RobertAndrews Se hai solobisogno deifigli di un singolotermine,puoi usare `get_term_children ($term,$taxonomy)` ([documentazione] (https://codex.wordpress.org/Function_Reference/get_term_children)). Se si desidera otteneretuttii figli delgenitore diprimo livello di un datotermine,èpossibilepassareil risultato sopra riportato,in questomodo: `get_term_children (get_term_top_most_parent ($term,$taxonomy),$taxonomy)`.

@RobertAndrews If you just need the children of a single term, you can use WordPress's built-in `get_term_children( $term, $taxonomy )` ([documentation](https://codex.wordpress.org/Function_Reference/get_term_children)). If you wanted to to get all children of a given term's top-level parent, you could pass the above result into it, like this: `get_term_children( get_term_top_most_parent( $term, $taxonomy ), $taxonomy )`.

Qual è $termin questo caso,ades.l'oggetto,ilnome deltermine,ilprefissotaxonomyname_number?Intuttii casi,questometodo èestremamente lungo da caricare.Ho aspettato che lapagina si caricasse da diversiminuti.

What is $term in this case, ie. the object, the name of the term, the prefixed taxonomyname_number? In all cases, this method is extremely long to load. I've been waiting for the page to load for several minutes now.

Come originariamente scritto,si aspettava un ID,ma homodificato la rispostaper consentire untermine ID o oggetto WP_Term. Non sei [l'unico] (https://wordpress.stackexchange.com/questions/63277/how-to-get-the-top-most-term-top-ancestor-of-a-custom-taxonomy-child-term? rq=1) segnala unproblema con questo codice -idealmente dovrebbeessere riscrittoper usare lafunzioneincorporata di WP `get_ancestors`,cheeranuovae nonben documentata quando la risposta è stata scritta.Pubblicherò unanuova risposta quando avròiltempo diprovare.

As originally written it expected an ID, but I edited the answer to allow a term ID or WP_Term object. You're [not the only one](https://wordpress.stackexchange.com/questions/63277/how-to-get-the-top-most-term-top-ancestor-of-a-custom-taxonomy-child-term?rq=1) reporting an issue with this code—ideally it should be rewritten to use WP's built-in `get_ancestors` function, which was new and not well documented when the answer was written. I will post a new answer when I've had time to test.
