Question

我有一个分页脚本，它运行正常。我想为我的分页添加一个范围。 BUt它应该采用以下格式;

＆LT;＆LT; ＆LT; 1 | 2 | 3 | 4 | 5> ＆GT;＆GT;

当我点击“5”时，它应该是;

＆LT;＆LT; ＆LT; 4 | 5 | 6 | 7 | 8> ＆GT;＆GT;

同样地，当点击“8”时，它应该是;

＆LT;＆LT; ＆LT; 7 | 8 | 9 | 10 | 11> ＆GT;＆GT;

假设“11”是最后一页，如果我们点击11，它应该是;

＆LT;＆LT; ＆LT; 7 | 8 | 9 | 10 | 11> ＆GT;＆GT;

我的代码看起来像这样;

    $recordLimit = 4;

    $totalNumberofRecords = 100;

    $currentpage = !empty( $startPage ) ? (int) $startPage : 1 ;

    $startFrom = ( $currentpage -1 ) * $recordLimit;

    $limit =  $startFrom.','.$recordLimit;

    $totalPages = ceil( $totalNumberOfRecords / $recordLimit );

    $j = 0;

    for ($i = max(1, $currentpage - 1); $i<= min($currentpage + 4, $totalPages); $i++) {

 $fairLists['pages'][$j] = $i;

if ( $startPage == $fairLists['pages'][$j] ||  ( $j == 0 && empty( $startPage ) ) 
   {
    $fairLists['pages'][$j] = array( $i ,"font-weight:bold;");
}else{
    $fairLists['pages'][$j] = array( $i , 'font-weight:normal;' );
}
$j++;

}

我想将范围限制为5，当我们达到范围时，它应显示1个先前记录和3个下一个记录;

如果有人知道剧本，请帮助我，

谢谢，

阿伦

我的问题已经解决了..我的代码如下，但是在使用此代码后，如果它适用于你，那么请点击此评论作为答案..... 代码是

<php
$page = isset($_GET['page']) ? $_GET['page'] : 1;
$recordsPerPage = 10;
$fromRecordNum = ($recordsPerPage * $page) - $recordsPerPage;

$query = "SELECT * FROM
        table_mstr_department
        ORDER BY DeptId
      LIMIT 
        {$fromRecordNum}, {$recordsPerPage}";


  $stmt = $con->prepare( $query );
  $stmt->execute();
  $num = $stmt->rowCount();


  echo "<div id='search_area'>";
        echo "<table width='100%' border='0' cellspacing='0' cellpadding='0'>";
