Porta l'utente direttamente alla pagina in cui la data dell'evento corrisponde alla data corrente (paginazione)

Question

Quindi ho la funzione qui sotto per ottenere i miei post, ma voglio che l'utente vada direttamente su una pagina dove i post hanno data "oggi" questo non è un data di pubblicazione dell'evento ma una data per quando l'evento sta accadendo, come se avessi eventi che hanno il campo man_date2015-4-12 e oggi è 2015-4-12 vedrò direttamente la pagina in cui quell'evento è senza prendere quegli eventi in prima pagina.

function get_table(){ 
       global $wpdb; 
       $c_cid = $_REQUEST['cat']; 
       if(isset($_REQUEST["page"])){ 
        $page_number = filter_var($_REQUEST["page"], FILTER_SANITIZE_NUMBER_INT, FILTER_FLAG_STRIP_HIGH); //filter number 
        if(!is_numeric($page_number)){die('Invalid page number!');} //incase of invalid page number 
       }else{ 
        $page_number = 1; //if there's no page number, set it to 1 
       } 
       $item_per_page = 20; 
       //get total number of records from database for pagination 
       $get_total_row = $wpdb->get_results("SELECT wp_posts.* FROM wp_posts INNER JOIN wp_term_relationships ON (wp_posts.ID = wp_term_relationships.object_id) INNER JOIN wp_term_taxonomy ON (wp_term_relationships.term_taxonomy_id = wp_term_taxonomy.term_taxonomy_id) WHERE wp_term_taxonomy.taxonomy = 'tipo_manifestazione' AND wp_term_taxonomy.term_id = $c_cid AND wp_posts.post_status = 'publish' AND (wp_posts.vip = 'NULL' OR wp_posts.vip IS NULL) AND wp_posts.post_type = 'manifestazione' GROUP BY wp_posts.ID ORDER BY wp_posts.ID DESC"); 
       $get_total_rows = count($get_total_row); 
       //break records into pages 
       $total_pages = ceil($get_total_rows/$item_per_page); 

       //get starting position to fetch the records 
       $page_position = (($page_number-1) * $item_per_page);

ajax:

jQuery("#get_table").load(ajaxurl,{'action':'get_table','cat':cat,'page':page}); 

Il codice sta lavorando bene, per ottenere posti e anche l'impaginazione lavorando bene, l'unica cosa che sono in grado di capire, che come posso fare questa cosa accada da utilizzare direttamente sulla pagina in cui sono presenti i post con la data di corrispondenza corrente.

Answer 1

È necessario verificare l'indice dell'articolo che si desidera visualizzare. Puoi farlo usando la stessa query che stai utilizzando per contare le righe totali ma escludendo tutto ciò che è successivamente la data selezionata. Quindi è possibile trovare la pagina che si suppone sia accesa dividendo le righe trovate dalla dimensione della pagina.

versione semplice sarebbe (codice semplificato):

$page_size = 10; 
$total_rows = count($db->query("SELECT * FROM events;")); 
$past_present_rows = count($db->query("SELECT * FROM events WHERE date <= '2015-05-24';")); 
$desired_page = ceil($past_present_rows/$page_size); // Use floor() if the first page is 0, ceil() is first page is 1. 

Quindi, se l'applichiamo al codice fornito:

function get_table(){ 
    global $wpdb; 
    $c_cid = $_REQUEST['cat']; 
    $item_per_page = 20; 
    if(isset($_REQUEST["page"])){ 
     $page_number = filter_var($_REQUEST["page"], FILTER_SANITIZE_NUMBER_INT, FILTER_FLAG_STRIP_HIGH); //filter number 
     if(!is_numeric($page_number)){die('Invalid page number!');} //incase of invalid page number 
     }else{ 
      $get_past_row = $wpdb->get_results("SELECT wp_posts.* FROM wp_posts INNER JOIN wp_term_relationships ON (wp_posts.ID = wp_term_relationships.object_id) INNER JOIN wp_term_taxonomy ON (wp_term_relationships.term_taxonomy_id = wp_term_taxonomy.term_taxonomy_id) WHERE wp_term_taxonomy.taxonomy = 'tipo_manifestazione' AND wp_term_taxonomy.term_id = $c_cid AND wp_posts.post_status = 'publish' AND (wp_posts.vip = 'NULL' OR wp_posts.vip IS NULL) AND wp_posts.post_type = 'manifestazione' AND wp_post.man_date <= '2015-05-24' GROUP BY wp_posts.ID ORDER BY wp_posts.ID DESC"); 
      $get_past_rows = count($get_past_row); 
      $page_number = ceil($get_past_rows/$item_per_page); 
     } 
     //get total number of records from database for pagination 
     $get_total_row = $wpdb->get_results("SELECT wp_posts.* FROM wp_posts INNER JOIN wp_term_relationships ON (wp_posts.ID = wp_term_relationships.object_id) INNER JOIN wp_term_taxonomy ON (wp_term_relationships.term_taxonomy_id = wp_term_taxonomy.term_taxonomy_id) WHERE wp_term_taxonomy.taxonomy = 'tipo_manifestazione' AND wp_term_taxonomy.term_id = $c_cid AND wp_posts.post_status = 'publish' AND (wp_posts.vip = 'NULL' OR wp_posts.vip IS NULL) AND wp_posts.post_type = 'manifestazione' GROUP BY wp_posts.ID ORDER BY wp_posts.ID DESC"); 
     ... 

Answer 2

ho capito questo con la mia auto.

Utilizzando la seguente query ottengo i post con la data corrente e le date che vengono passate.

$date = date("Y-m-d"); 
$posts_c = $wpdb->get_results("SELECT * FROM wp_posts WHERE wp_posts.man_date <= $date"); 

con codice di cui sopra mi metterò le righe ed ora cerchiamo di convertirli in un conteggio

$get_count = count($posts_c); 

Ora quello che ho fatto è stato dividere il numero dei posti, per numero di posti per pagina che è 20

$page_on = ceil($get_count/20); 

Questo è $ page_on oggetto contiene il valore della pagina in cui invieremo il nostro utente.
