Geçerli tarihin geçerli tarihle eşleştiği sayfaya doğrudan göz atın (sayfalandırma)

Question

Bu nedenle, yayınlarımı almak için aşağıdaki işleve sahibim, ancak kullanıcının doğrudan "bugün" yazan bir sayfanın üzerine gitmesini istiyorum. olayı yayınlama tarihi, ancak olayın gerçekleştiği tarih, alan 2015-4-12 alanım varsa ve bugün 2015-4-12 olduğu gibi, bu olayın ilk sayfada bu olayı görmediği sayfayı doğrudan göreceğim.

ajax: Kod iyi çalışıyor

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

, mesajları almak için ve ayrıca sayfalandırma iyi çalışma, ben edemiyorum tek şey ı Bu işi nasıl olduğunu, anlamaya Geçerli eşleşen tarihe sahip yayınların doğrudan sayfada kullanılması.

Answer 1

Göstermek istediğiniz öğenin indeksini kontrol etmelisiniz. Bunu, toplam satırları saymak için ancak daha sonra seçilen tarihte olan her şeyi hariç tutmak için kullandığınız sorguyu kullanarak yapabilirsiniz. Ardından, sayfa boyutunda bulunan satırları bölerek, olması gerektiğini düşündüğünüz sayfayı öğrenebilirsiniz.

$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. 

biz sağlanan kodu uygulamak Yani eğer: Ben öz tarafından bu anladım

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

Basit versiyon (basitleştirilmiş kodu) olacaktır.

Aşağıdaki sorguyu kullanarak, geçerli tarihe ve iletilen tarihlere sahip yayınları alıyorum. i satırları almak ve şimdi ne yaptım 20

sayfa başına yayın sayısından yayın sayısını bölmek oldu en Şimdi sayımı

$get_count = count($posts_c); 

onları dönüştürmek izin verir yukarıdaki kodu ile

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

$page_on = ceil($get_count/20); 

$ page_on nesnesi, kullanıcımızı göndereceğimiz sayfanın değerini içerir.
