Stomping WP_Query in archivio autore per facilitare l'impaginazione con query personalizzate

Question

Sto usando get_posts e get_comments di costruire diversi cicli sulla pagina, a cui sto avendo alcuni problemi in impaginazione.

Ho i messaggi globali opzione pagina (Impostazioni> lettura) insieme a al 10 , e questo sembra variare il problema. A partire da ora, posso facilmente arrivare a Pagina 2 - http : //dev.ashfame.com/author/ashfame/page/2/ , ma Pagina 3 restituisce un 404

.

Se abbasso il valore globale, che arriva ad avere pagine più impaginati ma non tutti (numero minore rispetto a quanti ci dovrebbe essere).

Aggiornamento: Ho appena provato a installare la mia impostazione personalizzata da 2 (e quello globale troppo), e WordPress dovrebbe impaginare fino 4 (ho 7 elementi per mostrare), ma ora lo fa, ma anche 5 e 6. 7 dà 404 . Perché? Come risolve questa cosa adesso?

Progress: @ t31os mi ha aiutato a capire che la sua la query predefinita WP sulla pagina, che sta allestendo l'impaginazione per quella pagina. Ora mi viene in mente un modo per uccidere la query WP predefinita in quella pagina (ma come?) E poi come faccio a impaginare ulteriormente la author.php ? O c'è qualche altro modo per farlo?

Codice attuale:

<?php

            $author_details = $wp_query->get_queried_object();

            // Posts Per Page option
            // $ppp = get_option('posts_per_page');
            $ppp = 1; //custom setting, if you want to obey the global setting here, comment this line and uncomment the above line

            if (!is_paged()) {
                $custom_offset = 0;
            } else {
                $custom_offset = $ppp*($paged-1);
            }

            echo '<h1>Author ID : '.$author_details->ID.', Page : '.$paged.', Custom Offset : '.$custom_offset.'</h1>';

            ?>

            <h2>Articles</h2>

            <?php

            );

            $posts_data = get_posts( $args );

            // print_r($posts_data);

            if ( count( $posts_data ) > 0 ) {

_{t31os dice: [Vedi la storia di modifica per il codice precedente e commenti]}

Utilizzo di Ajax per impaginare il tuo query

ho messo insieme un po 'di codice che verrà a prendere i tuoi post e commenti tramite la tecnologia AJAX utilizzando semplici prev / next navigazione tramite la tecnologia AJAX.

1) Sostituire tutto il codice che avete inviato in author.php con il seguente ..

<?php $cat_settings = array( 'Articles' => 7, 'Journals' => 6, 'Questions' => 3 ); ?>
<?php do_action( 'author_ajax_catposts', $cat_settings ); ?>

2) Creare un file javascript nel directory chiamata authorposts.js del vostro tema e inserire il seguente codice in quel file.

jQuery(document).ready( function($) {

    if( 'undefined' == typeof( aacVars ) )
        return;

    $('.aacnav').click(function() {

        var r = $( $(this).attr('href') );
        var a = $( $(this).attr('href') + '-ap' );
        var c = this.className.split(' ');

        if( 
            'undefined' == typeof( c ) || 
            'undefined' == typeof( r ) || 
            'undefined' == typeof( a ) 
        )
            return false;

        var d = { 
            action:      aacVars.posts_action, 
            _ajax_nonce: aacVars.nonce,
            author:      aacVars.author,
            category:    $(this).attr('href')
        };

        p = parseInt( a.text() );
        c = c.pop();

        switch( c ) {
            case 'aacnext':
                if( r.children('p.nomore').length )
                    return false;
                d.page = p + 1;
            break;
            case 'aacprev':
                if( p < 2 )
                    return false;
                d.page = p - 1;
            break;
            default:
                return false;
        }

        $.post( aacVars.ajaxpth, d, function( res ) {
            if( '-1' == res ) {
                alert( 'auth failed' );
                return false;
            }
            $( r ).html( res );
            $( a ).text( d.page );
        });

        return false;
    });

    $('.aacnavc').click(function() {

        var r = $( '#aac-comments' );
        var n = $( '#aac-comments-ap' );
        var l = $(this).attr('href');

        if( 
            'undefined' == typeof( n ) || 
            'undefined' == typeof( r ) 
        )
            return false;

        var d = { 
            action:      aacVars.comments_action, 
            _ajax_nonce: aacVars.nonce,
            author:      aacVars.author
        };

        p = parseInt( n.text() );

        switch( l ) {
            case '#next':
                if( r.children('p.nomore').length )
                    return false;
                d.page = p + 1;
            break;
            case '#prev':
                if( p < 2 )
                    return false;
                d.page = p - 1;
            break;
            default:
                return false;
        }

        $.post( aacVars.ajaxpth, d, function( res ) {
            if( '-1' == res ) {
                alert( 'auth failed' );
                return false;
            }
            r.html( res );
            $( n ).text( d.page );
        });

    });

});
