Come ottenere l'ID dell'autore fuori dal ciclo

Ilmodopiù semplicee direttoper ottenere l'ID dell'autore delpost al difuori del ciclo,se conosci l'ID delpost,è utilizzare lafunzioneprincipale di WordPress get_post_field() .

 $post_author_id = get_post_field( 'post_author', $post_id );
 

Senon conosci ancora l'ID delpost dellapaginain cuiti trovi,dal WP 3.1 la cosapiù semplice dafare è utilizzare funzione get_queried_object_id() (cercalonell'elenco deimetodi) chefunziona anche al difuori del ciclo.

 $post_id = get_queried_object_id();

The simplest and most straightforward way to get the post author ID outside the loop, if you know the post ID, is to use the WordPress core function get_post_field().

$post_author_id = get_post_field( 'post_author', $post_id );

If you do not yet know the post ID of the page you are on, then since WP 3.1 the easiest thing to do is use the get_queried_object_id()(look for it in the list of Methods) function which works even outside the loop.

$post_id = get_queried_object_id();

If these do not work for you then please give a more detailed explanation of where you are trying to run your code and we can see if we can help further.

Ecco come otteneree ottenere l'ID dell'autore al difuori del ciclo di WordPress:

 <?php
global $post;
$author_id=$post->post_author;
?>
 

Allora ci èpossibile the_author_meta:

 <?php
the_author_meta( 'user_nicename', $author_id );
?>
 

Here’s how to obtain and get the author ID outside the WordPress loop:

<?php
global $post;
$author_id=$post->post_author;
?>

Then it is possible to us the_author_meta:

<?php
the_author_meta( 'user_nicename', $author_id );
?>

Dipende da doveti trovi. Seti trovi su una singolapagina (adesempio,chemostra solo un singolo {{Insert Post Type Here}}),potresti utilizzare get_queried_object,che recupererà l'oggetto delpost.

 <?php
if (is_singular()) {
    $author_id = get_queried_object()->post_author;
    $address = get_the_author_meta('user_email', $author_id);
}
 

Seti trovi altrove,puoi utilizzare l'oggettoglobale $wp_querye controllare la suaproprietà $posts. Questo dovrebbefunzionare anche su singolepagine.

 <?php
global $wp_query;
if (!empty($wp_query->posts)) {
    $author_id = $wp_query->posts[0]->post_author;
    $address = get_the_author_meta('user_email', $author_id);
}
 

Puoi anche semplicemente "falsare l'avvio" del cicloe riavvolgerloper acquisire l'ID dell'autore. Ciònon comporterà alcun accesso al database aggiuntivo o simili. WordPress recuperatuttii post contemporaneamente (almomento della scrittura). rewind_posts ripristina semplicemente l'oggettopost corrente (l'oggettoglobale $post) all'inizio dell'array. Lo svantaggio è che ciòpotrebbe causare l'attivazione dell'azione loop_startmoltoprima di quanto desideri:non è ungrossoproblema,solo qualcosa di cuiessere a conoscenza.

 <?php
// make sure you're at the beginning.
rewind_posts();

// start the loop
the_post();

// get what you need
$address = get_the_author_meta('user_email');

// back to normal
rewind_posts();
 

Depends on where you are. If you're on a singular page (eg. only showing a single {{Insert Post Type Here}}), you could use get_queried_object, which will fetch the post object.

<?php
if (is_singular()) {
    $author_id = get_queried_object()->post_author;
    $address = get_the_author_meta('user_email', $author_id);
}

If you're anywhere else, you could use the global $wp_query object, and check its $posts property. This should work on singular pages as well.

<?php
global $wp_query;
if (!empty($wp_query->posts)) {
    $author_id = $wp_query->posts[0]->post_author;
    $address = get_the_author_meta('user_email', $author_id);
}

You can also just "false start" the loop and rewind it to grab the author ID. This will no incur any additional database hits or the like. WordPress fetches all posts at once (at the time of writing). rewind_posts just resets the current post (the global $post) object to the beginning of the array. The downside is that this may cause the loop_start action to fire way earlier than you want it to -- not a huge deal, just something to be aware of.

<?php
// make sure you're at the beginning.
rewind_posts();

// start the loop
the_post();

// get what you need
$address = get_the_author_meta('user_email');

// back to normal
rewind_posts();

Sembra chefunzioni al difuori del ciclo,forse questo aiuterà.

     $thelogin = get_query_var('author_name');
    $theauthor = get_userdatabylogin($thelogin);
 

Puoi ancheimpostaremanualmente l'ID delposte prenderloin questomodo:

 global $wp_query;
$thePostID = $wp_query->post->ID;
$postdata = get_post($thePostID, ARRAY_A);
$authorID = $postdata['post_author'];
 

Cambia IDin uscitaperpostaremanualmente l'IDper l'accesso out ofthe loop.

Non ottime soluzioni,ma si spera che aiuti.

This looks like it works outside of the loop, maybe this will help.

    $thelogin = get_query_var('author_name');
    $theauthor = get_userdatabylogin($thelogin);

You could also manually set ID of post and grab this way:

global $wp_query;
$thePostID = $wp_query->post->ID;
$postdata = get_post($thePostID, ARRAY_A);
$authorID = $postdata['post_author'];

Change ID out to post id manually for out of the loop access.

Not great solutions, but hopefully it helps.

Ho riscontrato lo stessoproblema qui duranteiltentativo di creare un widget chemostravapostin primopiano coninformazioni sull'autore.

Ho usato alcuni dei suggerimenti di @chrisguitarguy secondo suggerimento.

Ilmio codice aveva questo aspetto:

 <?php    

$count = 0;
$query_args = array(
      'posts_per_page' => 5,
     );
$com_query = new WP_Query( $query_args );

$feat_posts = $com_query->posts; // array, so we can access each post based on position

while ($com_query->have_posts()) {              
    $com_query->the_post();
        $author_name= get_the_author_meta('user_nicename',  $feat_posts[$count]->post_author);
        $count++;
}
 

I had the same issue here when trying to make a widget that displayed featured posts with author information.

I used some of the hint's from @chrisguitarguy 2nd tip.

My code looked like this:

<?php    

$count = 0;
$query_args = array(
      'posts_per_page' => 5,
     );
$com_query = new WP_Query( $query_args );

$feat_posts = $com_query->posts; // array, so we can access each post based on position

while ($com_query->have_posts()) {              
    $com_query->the_post();
        $author_name= get_the_author_meta('user_nicename',  $feat_posts[$count]->post_author);
        $count++;
}

Si spera che questopossa aiutare:

 $args= array(
    'post_type' =>'any',
    'post_status' => 'publish',
    'order' => 'ASC',
    'posts_per_page' => '-1'
);
$posts = new WP_Query($args);
$posts = $posts->posts;   

foreach($posts as $post) { 
  switch ($post->post_type) {
     case 'page': 
           // get the author's id through the post or page
           $id = get_post_field( 'post_author', $post->ID);
           // the first parameter is the name of the author 
           // of the post or page and the second parameter 
           // is the id with which the function obtains the name of the author.
           echo get_the_author_meta('display_name', $id);
        break;
    case 'post': 
         $id = get_post_field( 'post_author', $post->ID;
        echo get_the_author_meta('display_name', $id);
  }
}
 

Hopefully this wil help:

$args= array(
    'post_type' =>'any',
    'post_status' => 'publish',
    'order' => 'ASC',
    'posts_per_page' => '-1'
);
$posts = new WP_Query($args);
$posts = $posts->posts;   

foreach($posts as $post) { 
  switch ($post->post_type) {
     case 'page': 
           // get the author's id through the post or page
           $id = get_post_field( 'post_author', $post->ID);
           // the first parameter is the name of the author 
           // of the post or page and the second parameter 
           // is the id with which the function obtains the name of the author.
           echo get_the_author_meta('display_name', $id);
        break;
    case 'post': 
         $id = get_post_field( 'post_author', $post->ID;
        echo get_the_author_meta('display_name', $id);
  }
}

Per otteneree ottenere l'ID dell'autore al difuori del ciclo:

 global $post;
$author_id = $post->post_author;
 

Quindi utilizza

 get_the_author_meta('field_name', $author_id)
 

ricorda che se stai recuperando l'ID deipostin loope accedendo all'autore dal loop laterale,verrannoforniti soloi dati dell'ultimo IDpostin loop

To obtain and get the author ID outside the loop:

global $post;
$author_id = $post->post_author;

Then use

get_the_author_meta('field_name', $author_id)

remember if you are fetching posts id in loop and accessing author out side loop then it will only provide data of last post id in loop

Perchénon utilizzi the_author_meta

 <p>The email address for user id 25 is <?php the_author_meta('user_email',25); ?></p>
 

Puòessere utilizzato all'interno del ciclo

Why don't you use the_author_meta

<p>The email address for user id 25 is <?php the_author_meta('user_email',25); ?></p>

This can be used within the loop
