• WordPress custom loop with pagination

Fantastico come sempre Chip. In aggiunta a questo,considera la situazionein cui stai utilizzando unmodello dipaginaglobale allegato a una Paginaper unpo 'di "testointroduttivo"ed è seguito da una sottoquery che desideri vengaimpaginata.

Utilizzando paginate_links () come haimenzionato sopra,con lamaggiorparte dei valoripredefiniti (e supponendo chetu abbia abbastanzapermalink attivati)i tuoi collegamenti diimpaginazione sarannoimpostatiperimpostazionepredefinita su mysite.ca/page-slug/page/# che è adorabilemagenereràerrori 404perché WordPressnon lo sa su quellaparticolare struttura dell'URLe cercheràeffettivamente unapaginafiglia di "page" che siafiglia di "page-slug".

Iltrucco qui èinserire un'elegante regola di riscrittura che si applica solo a quelparticolare slug dipagina di "pseudopagina di archivio" che accetta la struttura /page/#/e la riscrivein una stringa di query che WordPress PUO 'capire,ovvero mysite.ca/?pagename=page-slug&paged=#. Nota pagenamee pagednon namee page (chemi ha causato letteralmente ORE di dolore,motivando questa risposta qui! ).

Ecco la regola di reindirizzamento:

 add_rewrite_rule( "page-slug/page/([0-9]{1,})/?$", 'index.php?pagename=page-slug&paged=$matches[1]', "top" );
 

Come sempre,quando simodificano le regole di riscrittura,ricordarsi di svuotarei permalink visitando Impostazioni> Permalinknelback-end amministrativo.

Se haipiùpagine che si comportanoin questomodo (adesempio,quando hai a chefare conpiùtipi dipostpersonalizzati),potresti volerevitare di creare unanuova regola di riscritturaper ogni slug dipagina. Possiamo scrivere un'espressione regolarepiùgenerica chefunzioniper qualsiasi slug dipaginaidentificato.

Un approccio è di seguito:

 function wpse_120407_pseudo_archive_rewrite(){
    // Add the slugs of the pages that are using a Global Template to simulate being an "archive" page
    $pseudo_archive_pages = array(
        "all-movies",
        "all-actors"
    );

    $slug_clause = implode( "|", $pseudo_archive_pages );
    add_rewrite_rule( "($slug_clause)/page/([0-9]{1,})/?$", 'index.php?pagename=$matches[1]&paged=$matches[2]', "top" );
}
add_action( 'init', 'wpse_120407_pseudo_archive_rewrite' );
 

Svantaggi/avvertenze

Uno svantaggio di questo approccio chemi fa vomitare unpo 'inbocca è l'hard-coding del Page slug. Se un amministratore cambiamai lo slug dellapagina di quellapaginapseudo-archivio,seibrindisi: la regola di riscritturanon corrisponderàpiùe otterraiiltemuto 404.

Non sono sicuro dipoterpensare a una soluzione alternativaper questometodo,ma sarebbebello sefosseilmodello dipaginaglobale a attivarein qualchemodo la regola di riscrittura. Ungiornopotrei rivedere questa risposta senessun altro ha risolto quelparticolare dado.

Awesome as always Chip. As an addendum to this, consider the situation whereby you are using a global page template attached to a Page for some "intro text" and it's followed by a subquery that you want to be paged.

Using paginate_links() as you mention above, with mostly defaults, (and assuming you have pretty permalinks turned on) your pagination links will default to mysite.ca/page-slug/page/# which is lovely but will throw 404 errors because WordPress doesn't know about that particular URL structure and will actually look for a child page of "page" that's a child of "page-slug".

The trick here is to insert a nifty rewrite rule that only applies to that particular "pseudo archive page" page slug that accepts the /page/#/ structure and rewrites it to a query string that WordPress CAN understand, namely mysite.ca/?pagename=page-slug&paged=#. Note pagename and paged not name and page (which caused me literally HOURS of grief, motivating this answer here!).

Here's the redirect rule:

add_rewrite_rule( "page-slug/page/([0-9]{1,})/?$", 'index.php?pagename=page-slug&paged=$matches[1]', "top" );

As always, when changing rewrite rules, remember to flush your permalinks by visiting Settings > Permalinks in the Admin back-end.

If you have multiple pages that are going to behave this way (for example, when dealing with multiple custom post types), you might want to avoid creating a new rewrite rule for each page slug. We can write a more generic regular expression that works for any page slug you identify.

One approach is below:

function wpse_120407_pseudo_archive_rewrite(){
    // Add the slugs of the pages that are using a Global Template to simulate being an "archive" page
    $pseudo_archive_pages = array(
        "all-movies",
        "all-actors"
    );

    $slug_clause = implode( "|", $pseudo_archive_pages );
    add_rewrite_rule( "($slug_clause)/page/([0-9]{1,})/?$", 'index.php?pagename=$matches[1]&paged=$matches[2]', "top" );
}
add_action( 'init', 'wpse_120407_pseudo_archive_rewrite' );

Disadvantages / Caveats

One disadvantage of this approach that makes me puke in my mouth a little is the hard-coding of the Page slug. If an admin ever changes the page slug of that pseudo-archive page, you're toast - the rewrite rule will no longer match and you'll get the dreaded 404.

I'm not sure I can think of a workaround for this method, but it would be nice if it were the global page template that somehow triggered the rewrite rule. Some day I may revisit this answer if no one else has cracked that particular nut.

Homodificato la query del cicloprincipaletramite query_posts(). Perché l'impaginazionenonfunzionae come risolverlo?

Ottima risposta Il chip creato deveesseremodificato oggi.
Da qualchetempo abbiamo la variabile $wp_the_query che dovrebbeessere uguale alla $wp_queryglobale subito dopo l'esecuzione della queryprincipale.

Questo èilmotivoper cui questa è laparte della risposta del Chip:

Hacking dell'oggetto queryprincipale

non èpiùnecessario. Possiamo dimenticare questaparte con la creazione della variabiletemporanea.

 // Pagination fix
$temp_query = $wp_query;
$wp_query   = NULL;
$wp_query   = $custom_query;
 

Quindi orapossiamo chiamare:

 $wp_query   = $wp_the_query;
 

o anchemegliopossiamo chiamare:

 wp_reset_query();
 

Tutto ciò che ha delineatogli altri Chip rimane. Dopo quellaparte di ripristino della query èpossibile chiamare lefunzioni diimpaginazione che sono f($wp_query),- dipendono da $wp_queryglobale.

Permigliorare ulteriormente lameccanica dell'impaginazionee per darepiù libertà allafunzione query_posts ho creato questopossibilemiglioramento:

https://core.trac.wordpress.org/ticket/39483

I have modified the main loop query via query_posts(). Why isn't pagination working, and how do I fix it?

Great answer Chip created needs to be modified today.
For some time we have $wp_the_query variable that should be equal to the $wp_query global just after the main query executes.

This is why this the part from the Chip's answer:

Hack the main query object

is not needed anymore. We can forget this part with creating the temporary variable.

// Pagination fix
$temp_query = $wp_query;
$wp_query   = NULL;
$wp_query   = $custom_query;

So now we can call:

$wp_query   = $wp_the_query;

or even better we can call:

wp_reset_query();

Everything other Chip outlined stays. After that query-reset-part you can call the pagination functions that are f($wp_query), — they depend on $wp_query global.

In order to further improve the pagination mechanics and to give more freedom to the query_posts function I created this possible improvement:

https://core.trac.wordpress.org/ticket/39483

        $paged = get_query_var('paged', 1);

        'order' => 'DESC',
        'posts_per_page' => 20,
        'paged' => $paged 
    );
    $query = new WP_Query($args);
