極限分頁頁碼

Question

$objConnect = mysql_connect("localhost","root","") or die(mysql_error()); 
$objDB = mysql_select_db("Test"); 

$strSQL = "SELECT * FROM UserAddedRecord WHERE (Name LIKE '%".$getname."%' and State LIKE '%".$getstate."%' and Cell LIKE '%".$getcell."%' and Custgroup LIKE '%".$getgroup."%') AND user_id=$id"; 

$objQuery = mysql_query($strSQL) or die ("Error Query [".$strSQL."]"); 
$Num_Rows = mysql_num_rows($objQuery); 

$Per_Page = 5; 

if (!isset($_GET['Page'])) { 
    $Page = 1; 
} else { 
    $Page = $_GET['Page']; 
} 

$Prev_Page = $Page - 1; 
$Next_Page = $Page + 1; 

$Page_Start = (($Per_Page * $Page) - $Per_Page); 
if ($Num_Rows <= $Per_Page) { 
    $Num_Pages = 1; 
} elseif (($Num_Rows % $Per_Page) == 0) { 
    $Num_Pages = ($Num_Rows/$Per_Page) ; 
} else { 
    $Num_Pages = ($Num_Rows/$Per_Page) + 1; 
    $Num_Pages = (int) $Num_Pages; 
} 


$strSQL .=" order by addedrec_ID DESC LIMIT $Page_Start , $Per_Page";

mysql_close($objConnect); 

這是我用來爲數據搜索創建分頁頁面的代碼。但我只注意到我有太多的記錄，那麼它會有太多的頁碼。我試圖限制頁碼顯示，並尋找很多例子..它有很多方法來做到這一點，但我仍然不知道如何限制它爲我的方法...

Answer 1

好吧，如果你的意思是表明像

Prev 1 2 3 4 5 6 .. 40 41 Next 
Prev 1 2 .. 6 7 8 9 10 .. 40 41 Next 

第一件事情，我們需要的就是創建一個可以處理功能我們需要輸出分頁。這裏有一個我使用的功能，它運行良好。

function get_paging_info($tot_rows,$pp,$curr_page) 
{ 
    $pages = ceil($tot_rows/$pp); // calc pages 

    $data = array(); // start out array 
    $data['si']  = ($curr_page * $pp) - $pp; // what row to start at 
    $data['pages']  = $pages;     // add the pages 
    $data['curr_page'] = $curr_page;    // Whats the current page 

    return $data; //return the paging data 

} 

現在這個功能非常穩定，對我來說效果很好。

所以，你通過這個功能

• $ tot_rows =計行查詢
• $頁=每頁項目
• $ curr_page =當前頁碼

好了，現在你有你需要的數據，你需要顯示它。

下面是我用的，請在你想'啊，太長了'之前閱讀它。這其實很簡單。

繼承人的快照，它會返回

<!-- Create the query --> 
    <?php $count = mysql_fetch_assoc(mysql_query ("SELECT COUNT(rows) as count FROM table")) ; 

    <?php $count = $count[0]['count']; ?> 

<!-- Call our function from above --> 
<?php $paging_info = get_paging_info($count,5,34); ?> 


<p> 
    <!-- If the current page is more than 1, show the First and Previous links --> 
    <?php if($paging_info['curr_page'] > 1) : ?> 
     <a href='' title='Page 1'>First</a> 
     <a href='' title='Page <?php echo ($paging_info['curr_page'] - 1); ?>'>Prev</a> 
    <?php endif; ?> 



    <?php 
     //setup starting point 

     //$max is equal to number of links shown 
     $max = 7; 
     if($paging_info['curr_page'] < $max) 
      $sp = 1; 
     elseif($paging_info['curr_page'] >= ($paging_info['pages'] - floor($max/2))) 
      $sp = $paging_info['pages'] - $max + 1; 
     elseif($paging_info['curr_page'] >= $max) 
      $sp = $paging_info['curr_page'] - floor($max/2); 
    ?> 

    <!-- If the current page >= $max then show link to 1st page --> 
    <?php if($paging_info['curr_page'] >= $max) : ?> 

     <a href='' title='Page 1'>1</a> 
     .. 

    <?php endif; ?> 

    <!-- Loop though max number of pages shown and show links either side equal to $max/2 --> 
    <?php for($i = $sp; $i <= ($sp + $max -1);$i++) : ?> 

     <?php 
      if($i > $paging_info['pages']) 
       continue; 
     ?> 

     <?php if($paging_info['curr_page'] == $i) : ?> 

      <span class='bold'><?php echo $i; ?></span> 

     <?php else : ?> 

      <a href='' title='Page <?php echo $i; ?>'><?php echo $i; ?></a> 

     <?php endif; ?> 

    <?php endfor; ?> 


    <!-- If the current page is less than say the last page minus $max pages divided by 2--> 
    <?php if($paging_info['curr_page'] < ($paging_info['pages'] - floor($max/2))) : ?> 

     .. 
     <a href='' title='Page <?php echo $paging_info['pages']; ?>'><?php echo $paging_info['pages']; ?></a> 

    <?php endif; ?> 

    <!-- Show last two pages if we're not near them --> 
    <?php if($paging_info['curr_page'] < $paging_info['pages']) : ?> 

     <a href='<?php echo str_replace('/page'.$paging_info['curr_page'], '', $paging_info['curr_url']) . '/page'.($paging_info['curr_page'] + 1); ?>' title='Page <?php echo ($paging_info['curr_page'] + 1); ?>'>Next</a> 

     <a href='<?php echo str_replace('/page'.$paging_info['curr_page'], '', $paging_info['curr_url']) . '/page'.$paging_info['pages']; ?>' title='Page <?php echo $paging_info['pages']; ?>'>Last</a> 

    <?php endif; ?> 
</p> 

Answer 2

您將需要使用您的LIMIT條款在您的sql語句。例如：

SELECT <column> 
    FROM <table> 
    LIMIT 0, 5 

參考：SELECT Syntax

Answer 3

我解決了一個非常類似的問題，別人用一個非常類似的腳本在這裏：How to limit pages shown in pagination script

而且，我注意到一些其他的異常與腳本（除了我固定的不可讀格式）。您應該將所有出現的$_SERVER[SCRIPT_NAME]更改爲$_SERVER['SCRIPT_NAME']。在腳本中，例如：

echo " <a href ='$_SERVER[SCRIPT_NAME]?Page=..."; 

將成爲：

echo " <a href ='{$_SERVER['SCRIPT_NAME']}?Page=...";

我的代碼總是顯示至少9頁的總頁數的情況下> 9不管你是1,2,3

頁

<ul class="pagination pagination-sm" style="align:center"> 
    <li><a href="./?page=1"><</span></a></li>

      for($i = 1; $i <= $total_pages; $i++) 
      { 

       if ($i == $current_page)

        echo '<li class="active"><a href="#">'; echo $i.'</a></li>'."\n";

Answer 5

目的本代碼是隻顯示在分頁的頁面明確的（某些）號

從以下網址獲取當前頁碼和mysql的定義總頁數的$curr_pg_numb

獲取數量和定義$total_pages

這裏是分頁代碼

$counter=0; 
$init_num_to_left = 3;//initial number of pages to show to left from current page 
$init_num_to_right = 4; 

if($curr_pg_numb - $init_num_to_left < 1){ 
$init_num_to_right = $init_num_to_right + (1 - ($curr_pg_numb - $init_num_to_left)); 
$init_num_to_left = $curr_pg_numb - 1; 
} 
else if($curr_pg_numb + $init_num_to_right > $total_pages){ 
$init_num_to_left = $init_num_to_left + (($curr_pg_numb + $init_num_to_right) - $total_pages); 
$init_num_to_right = ($curr_pg_numb + $init_num_to_right) - $total_pages; 
} 

while($counter <= $total_pages) { 
    if ($counter > 0){ 
    if ($curr_pg_numb==$counter){ 
    echo '<strong> '. (htmlspecialchars($curr_pg_numb , ENT_QUOTES, "UTF-8") + 0). '</strong> '; 
    } 
    else { 
    if ($counter >= ($curr_pg_numb - $init_num_to_left) and $counter <= ($curr_pg_numb + $init_num_to_right)) { 
    echo '<a href="?cpn='. htmlspecialchars(($counter), ENT_QUOTES, "UTF-8"). '" style="margin:5px;">'. htmlspecialchars(($counter), ENT_QUOTES, "UTF-8"). '</a>'; 
    } 
    }//else { 
    }//if ($counter > 0){ 
$counter++; 
}//while($counter <= $total_pages) { 

Answer 6

$ count_pages =小區（$總/ $ items_per_page的）;

Answer 7

使其簡單，這裏是代碼：

<?php  
    //put this code on the begining of the page 
    $page=$_GET['page']; //Getting page number from url | example: www.mydomain.com/index.php?page=3 
    if(!is_numeric($page)) $page=1; //If there is no page number specified we set number 1 
$queryCount = "SELECT * FROM table "; //select from db 
$query = $DB->query($queryCount); 
    $num = mysql_num_rows ($query); //count num rows 
    $per_page=5; //default 5 results per page 
$start=$per_page*($page-1); //start for select on next page (page2, 3, 4,5) 
$end=min($num,$page*$per_page); //end 


//here is select for your results. Be careful for LIMIT in the select! 
$query = "SELECT * FROM page LIMIT $start, $per_page "; 


//page bottom, where you want to put your numbers 
$pages=ceil($num/$per_page); 
    for($s=1; $s<=$pages; $s++) 
    { 
    if($s==$page) 
     $numPage .= "[$s] "; 
    else 
     $numPage .= "<a href='index.php?page=$s'>$s</a> "; 
    } 

echo $numPage;

我沒有測試它，但我認爲它必須努力:-)
