¿Esposible obtenerelenlacepermanente de unapágina solo desdeel slug?Soy consciente de quepuede obtenerelenlacepermanente de lapágina apartir del ID utilizando get_page_link():

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

Tengo curiosidadpor saber si hay algunaforma de hacer lomismo conel slug de unapágina,comoesta:

<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

Creo queestopodría sermejor:

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; }

siguiendoelpatrón "original" get_page_by_title de wordpress .(línea 3173)

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. (line 3173)

- Último comentario: creo que sql debetener una condiciónmás: `functionget_page_by_slug ($page_slug,$ output=OBJECT,$post_type='page') {global $ wpdb;$página=$ wpdb->get_var ($ wpdb->prepare ("SELECCIONAR ID DE $ wpdb->publicaciones DONDEpost_name=% s Ypost_type=% s ANDpost_status='publicar'",$page_slug,$post_type));if ($página) returnget_page ($página,$ salida);devolvernulo;} `
  
  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; }`

- ¿Por qué?Nogenera un objeto depublicación completo solopara obtener laidentificación.
  
  Why? It doesn't generate a complete post object just to get the ID.

- @webcitron Creo que soloporque sigueelpatrón original de Wordpress recibiendopublicacionespor 'título',simplemente cambiandopor 'slug'. (consulteel [enlace] (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))

- Estaes unabuena respuesta.Estoevita laposibilidad de que un complementomaliciosoenmascare supágina o lafiltreincorrectamente.Si devuelve laidentificación de latabla depublicaciones,puede crear unainstancia de `\ WP_Post` apartir deella,yeso se resuelve directamenteen todas lasfunciones de wordpress que comprueban otros valores.`\ WP_Post`tambiénproporcionamétodos directamenteparaencontrar lamayoría de los datos relacionados con lapublicación.
  
  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.

Estees unmétodopublicadopor Tom McFarlin en sublog :

 /**
 * 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;
}

Funciona contipos depublicacionespersonalizadas ytipos depublicacionesintegrados (como post y page).

This is a method published by Tom McFarlin on his blog:

function wpse_4999_get_permalink_by_slug( $slug, $post_type = '' ) {

    // Initialize the permalink value
    $permalink = null;

    // Build the arguments for WP_Query

    // 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 respuesta aceptadaesincorrectaporque laspáginasjerárquicasnofuncionan así.Enpocaspalabras,lababosano siemprees la ruta de lapágina opublicación.P.ej.supáginatiene un hijo,etc. la ruta será parent-slug/child-slug y get_page_by_pathnopodráencontrar child-slug deestamanera.La solución adecuadaesesta:

 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>

Pruebeesto:

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

get_page_by_path( 'path' ) devuelveel objeto depágina/publicación que luegopuede ser utilizadopor get_page_link() ya que aceptael objeto depublicación/página y devuelveelenlacepermanente.
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

Utiliceestafunción antes de

 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

Estás hablando depáginas,¿verdad?Nopublicaciones.

¿Esesto lo quebusca?

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

¿Quiso decir `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) devuelve unamatriz detoda lainformación de lapágina.[`get_permalink ()`] (http://codex.wordpress.org/Function_Reference/get_permalink)toma una ID depágina comoprimer argumento.Pensé quetendría quepasarexplícitamenteel valor de 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: No siempreestá documentado,peromuchasfunciones de WP aceptantanto IDnuméricos como objetos depublicación completos como argumento.

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

Parece queget_page_by_path ()puede serbastante complicado de usar cuando setrata depáginas secundarias ...

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

respuestaincorrecta,votonegativo alnirvana,porfavor.El caminonoeselmismo queel de lababosa.Ejemplo: unapáginatiene unapáginaprincipal llamada `abc`,lapáginaen sítiene un slug de` 123`.La ruta ahoraes `abc/123` yel sluges` 123`.Eliminaesta respuestaincorrecta.`get_page_by_path ('123')`nofuncionará.

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.

Enmi caso,tuve que usarelprimero yfuncionóbien,porqueel segundo (get_page_by_title)estaba devolviendo otroenlace depublicación (nopágina) con un slug similar (peronoelmismo).No sépor quéestabapasandoesto.

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.
