Èpossibile ottenereilpermalink di unapagina solo dallo slug?Sono consapevole delfatto chepuoi ottenereilpermalink dellapagina dall'ID utilizzando get_page_link():

<a href="<?php echo get_page_link(40); ?>">Map</a>

Sono curioso di sapere seesiste unmodoperfare lo stesso con lo slug di unapagina,come questo:

<a href="<?php echo get_page_link('map'); ?>">Map</a>
Is it possible to get a page's permalink from the slug alone? I'm aware that you can get the page's permalink from the ID using get_page_link():

<a href="<?php echo get_page_link(40); ?>">Map</a>

I'm curious if there is any way to do the same with the slug of a page - like this:

<a href="<?php echo get_page_link('map'); ?>">Map</a>
permalinks pages slug

Penso chepotrebbeesseremigliore:

funzioneget_page_by_slug ($page_slug,$ output=OBJECT,$post_type='page') { global $ wpdb; $page=$ wpdb- >get_var ($ wpdb- >prepare ("SELEZIONA ID DA $ wpdb- >posts WHEREpost_name=% sepost_type=% s",$page_slug,$post_type)); if ($pagina) returnget_page ($page,$ output); returnnull; }

seguendo lo schema di get_page_by_title di wordpress .(riga 3173)
rgds
I think this could be better: function get_page_by_slug($page_slug, $output = OBJECT, $post_type = 'page' ) { global $wpdb; $page = $wpdb->get_var( $wpdb->prepare( "SELECT ID FROM $wpdb->posts WHERE post_name = %s AND post_type= %s", $page_slug, $post_type ) ); if ( $page ) return get_page($page, $output); return null; } following the pattern of "original" get_page_by_title of wordpress.

Perché sarebbemeglio?Puoi spiegare? Why would that be better? Can you explain? 11 2012-04-11 julien_c Ultimo commento - Penso che sql abbiabisogno di un'altra condizione: `functionget_page_by_slug ($page_slug,$ output=OBJECT,$post_type='page') {global $ wpdb;$page=$ wpdb->get_var ($ wpdb->prepare ("SELECT ID FROM $ wpdb->posts WHEREpost_name=% s ANDpost_type=% s ANDpost_status='publish'",$page_slug,$post_type));if ($page) restituisceget_page ($page,$ output);returnnull;} " Last comment - I think that sql needs to have one more condition: `function get_page_by_slug($page_slug, $output = OBJECT, $post_type = 'page' ) { global $wpdb; $page = $wpdb->get_var( $wpdb->prepare( "SELECT ID FROM $wpdb->posts WHERE post_name = %s AND post_type= %s AND post_status = 'publish'", $page_slug, $post_type ) ); if ( $page ) return get_page($page, $output); return null; }` 0 2013-01-09 Perché?Nongenera un oggettopost completo soloper ottenere l'ID. Why? It doesn't generate a complete post object just to get the ID. 0 2013-01-09 s_ha_dum @webcitronpenso soloperché sta seguendoilmodello originale di Wordpress ricevendopostper "titolo",cambiando soloper "slug". (controllail [link] (http://core.trac.wordpress.org/browser/tags/3.1/wp-includes/post.php#L3173)) @webcitron I think just because is following original pattern of Wordpress getting post by 'title', just changing for 'slug'. (check the [link](http://core.trac.wordpress.org/browser/tags/3.1/wp-includes/post.php#L3173)) 0 2013-05-13 Matheus Eduardo Questa è unabuona risposta.Ciò aggira lapossibilità che unpluginnon autorizzatomascheri latuapagina o lafiltriin modoerrato.Se restituisci l'id dallatabella deipost,puoi creare un'istanza di `\ WP_Post` daessa,e questo si risolve direttamentein tutte lefunzioni di wordpress che controllano altri valori."\ WP_Post"fornisce anchemetodipertrovare direttamente lamaggiorparte dei dati relativi alpost. This is a good answer. This bypasses the possiblity of a rogue plugin masking your page or incorrectly filtering it. If you return the id from the post table, then you can create an instance of `\WP_Post` from it, and that resolves directly in all of the wordpress functions that check for other values. `\WP_Post` also provides methods directly to find most related data about the post. 0 2018-03-23 mopsyd

Questo è unmetodopubblicato da Tom McFarlin sul suoblog :
/** * Restituisceilpermalinkper unapaginain base allo slugin arrivo. * * @param string $ slug Lo slug dellapagina a cui ci collegheremo. * @return string Ilpermalink dellapagina * @ dalla 1.0 */ funzione wpse_4999_get_permalink_by_slug ($ slug,$post_type='') { //Inizializzail valore delpermalink $permalink=null; //Creagli argomentiper WP_Query $ args=array ( "nome"=> $ slug, "max_num_posts"=> 1 ); //Se l'argomento opzionale èimpostato,aggiungerlo all'array degli argomenti if (''!=$post_type) { $ args=array_merge ($ args,array ('post_type'=> $post_type)); } //Esegui la query (e ripristinala) $ query=new WP_Query ($ args); if ($ query- > have_posts ()) { $ query- >the_post (); $permalink=get_permalink (get_the_ID ()); wp_reset_postdata (); } return $permalink; }

Funziona contipi dipostpersonalizzatie tipi dipostincorporati (come post e page ).
This is a method published by Tom McFarlin on his blog:

/** * Returns the permalink for a page based on the incoming slug. * * @param string $slug The slug of the page to which we're going to link. * @return string The permalink of the page * @since 1.0 */ function wpse_4999_get_permalink_by_slug( $slug, $post_type = '' ) { // Initialize the permalink value $permalink = null; // Build the arguments for WP_Query $args = array( 'name' => $slug, 'max_num_posts' => 1 ); // If the optional argument is set, add it to the arguments array if( '' != $post_type ) { $args = array_merge( $args, array( 'post_type' => $post_type ) ); } // Run the query (and reset it) $query = new WP_Query( $args ); if( $query->have_posts() ) { $query->the_post(); $permalink = get_permalink( get_the_ID() ); wp_reset_postdata(); } return $permalink; }

It works with custom post types and built-in post types (such as post and page).

la risposta accettata è sbagliataperché lepaginegerarchichenonfunzionanoin questomodo.Inpocheparole,lo slugnon è sempreilpercorso dellapagina o delpost.Peresempio.latuapagina ha unfiglioecc.ilpercorso sarà parent-slug/child-sluge get_page_by_pathnon riuscirà atrovare child-slugin questomodo.La soluzione corretta è questa:

 function mycoolprefix_post_by_slug($the_slug, $post_type = "page"){
 $args = array(
   'name'        => $the_slug,
   'post_type'   => $post_type,
   'post_status' => 'publish',
   'numberposts' => 1
 );
 $my_page = get_posts($args)[0];
 return $my_page;
}

<a href="<?php echo mycoolprefix_post_by_slug('map'); ?>">Map</a>

the accepted answer is wrong because hierarchical pages don't work like that. Simply put, the slug is not always the path of the page or post. E.g. your page has a child etc. the path will be parent-slug/child-slug and get_page_by_path will fail to find child-slug this way. The proper solution is this:

function mycoolprefix_post_by_slug($the_slug, $post_type = "page"){
 $args = array(
   'name'        => $the_slug,
   'post_type'   => $post_type,
   'post_status' => 'publish',
   'numberposts' => 1
 );
 $my_page = get_posts($args)[0];
 return $my_page;
}

<a href="<?php echo mycoolprefix_post_by_slug('map'); ?>">Map</a>

Prova questo:

<a href="<?php echo get_page_link( get_page_by_path( 'map' ) ); ?>">Map</a>

get_page_by_path( 'path' ) restituisce un oggettopage/post chepuòessere quindi utilizzato da get_page_link()poiché accetta l'oggettopost/pagee restituisceilpermalink.
Try This:

<a href="<?php echo get_page_link( get_page_by_path( 'map' ) ); ?>">Map</a>

get_page_by_path( 'path' ) returns page/post object which can be then used by get_page_link() as it accepts post/page object and returns permalink.

     function theme_get_permalink_by_title( $title ) {

    // Initialize the permalink value
    $permalink = null;

    // Try to get the page by the incoming title
    $page = get_page_by_title( strtolower( $title ) );

    // If the page exists, then let's get its permalink
    if( null != $page ) {
        $permalink = get_permalink( $page->ID );
    } // end if

    return $permalink;

} // end theme_get_permalink_by_title

Utilizza questafunzioneper

 if( null == theme_get_permalink_by_title( 'Register For This Site' ) ) {
  // The permalink doesn't exist, so handle this however you best see fit.
} else {
  // The page exists, so do what you need to do.
} // end if/else

    function theme_get_permalink_by_title( $title ) {

    // Initialize the permalink value
    $permalink = null;

    // Try to get the page by the incoming title
    $page = get_page_by_title( strtolower( $title ) );

    // If the page exists, then let's get its permalink
    if( null != $page ) {
        $permalink = get_permalink( $page->ID );
    } // end if

    return $permalink;

} // end theme_get_permalink_by_title

Use this function by

if( null == theme_get_permalink_by_title( 'Register For This Site' ) ) {
  // The permalink doesn't exist, so handle this however you best see fit.
} else {
  // The page exists, so do what you need to do.
} // end if/else

Staiparlando di Pages,giusto?Nonpost.

È questo quello che stai cercando:

get_permalink( get_page_by_path( 'map' ) )
get_permalink( get_page_by_title( 'Map' ) )
home_url( '/map/' )

Volevi dire `get_permalink (get_page_by_path ('contact') -> ID));`?

Did you mean `get_permalink(get_page_by_path('contact')->ID));`?

[`get_page_by_path ()`] (http://codex.wordpress.org/Function_Reference/get_page_by_path) restituisce un array ditutte leinformazioni sullapagina.[`get_permalink ()`] (http://codex.wordpress.org/Function_Reference/get_permalink) accetta un IDpagina comeprimo argomento.Hopensato di doverpassareesplicitamenteil valore ID.

[`get_page_by_path()`](http://codex.wordpress.org/Function_Reference/get_page_by_path) returns an array of all page information. [`get_permalink()`](http://codex.wordpress.org/Function_Reference/get_permalink) takes a page ID as the first argument. I thought I'd have to explicitly pass the ID value.

@ Jonathan:non è sempre documentato,mamoltefunzioni WP accettano sia IDnumerici che oggettipost completi come argomento.

@Jonathan: It's not always documented, but many WP functions accept both numeric ID's and full post objects as the argument.

Sembra cheget_page_by_path ()possaessere abbastanza complicato da usare quando sitratta dipaginefiglie ...

It seems that get_page_by_path() can be quite complicated to use when dealing with child pages...

risposta sbagliata,votonegativo alnirvanaperfavore.Ilpercorsonon è lo stesso della lumaca.Esempio: unapagina ha unapaginagenitore chiamata `abc` lapagina stessa ha uno slug di` 123`.Ilpercorso ora è `abc/123` lo slug è` 123`.Siprega di rimuovere questa risposta sbagliata.`get_page_by_path ('123')`nonfunzionerà.

wrong answer, downvote to nirvana please. The path is not the same like the slug. Example: a page has a parent page called `abc` the page itself has a slug of `123`. The path now is `abc/123` the slug is `123`. Please remove this wrong answer. `get_page_by_path( '123' )` wont work.

Nelmio caso ho dovuto usareilprimoe hafunzionatobene,perchéil secondo (get_page_by_title) stava restituendo un altro collegamento dipost (non dipagina) con uno slug simile (manon lo stesso).Non soperché stava succedendo.

In my case I had to use the first one and it worked fine, because the second one (get_page_by_title) was returning another post (not page) link with similar (but not the same) slug. I don't know why this was happening.
