我使用本教程使用分页。

一切正常，但我想更改页码的显示。

教程代码生成页面链接如下。

For page 1 : [1] 2 3 4 > >>
For page 6 : << < 3 4 5 [6] 7 8 9 > >> ( 3 pages range before and after).

我要更改的是仅显示 5 页。

For page 1: [1] 2 3 4 5 > >>
For page 3: 1 2 [3] 4 5 > >>
For page 5: 1 2 3 4 [5] > >>
For page 6: << < [6] 7 8 9 10 > >>
For page 10: << < 6 7 8 9 [10] > >>

我认为这部分需要改变。我试图搜索其他文章，但我找不到任何文章。什么是改变的好逻辑？谢谢。

// loop to show links to range of pages around current page
for ($x = ($currentpage - $range); $x < (($currentpage + $range) + 1); $x++) {
   // if it's a valid page number...
   if (($x > 0) && ($x <= $totalpages)) {
      // if we're on current page...
      if ($x == $currentpage) {
         // 'highlight' it but don't make a link
         echo " [<b>$x</b>] ";
      // if not current page...
      } else {
         // make it a link
         echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$x'>$x</a> ";
      } // end else
   } // end if 
} // end for

添加：

最后一页也是 5 页格式

For page 1: [1] 2 3 4 5 > >>
For page 3: 1 2 [3] 4 5 > >>
For page 5: 1 2 3 4 [5] > >>
For page 6: << < [6] 7 8 9 10 > >>
For page 10: << < 6 7 8 9 [10] > >>
For last page 12: << < 8 9 10 11[12]

我正在尝试将 5 个页码作为组放入数组中，以与 in_array 一起使用。还没有成功。

添加：

不知何故，我让它工作......但当前页面总是在中心，这不是我想要的...... :(

// range of num links to show
//$range = 3;
$range = 2;

....

// Added from here...    
if (($currentpage - $range) <= 1){
    $start_x = 1;
    $end_x = 5; 
}
else if ($currentpage >= ($totalpages - $range)){
    $start_x = $totalpages - 4;
    $end_x = $totalpages;
}
else {  
    $start_x = $currentpage - $range;
    $end_x = $currentpage + $range;
}
// Until here

// loop to show links to range of pages around current page
// for ($x = ($currentpage - $range); $x < (($currentpage + $range) + 1); $x++) {
for ($x = $start_x; $x < ($end_x + 1); $x++) {
   // if it's a valid page number...
   if (($x > 0) && ($x <= $totalpages)) {
      // if we're on current page...
      if ($x == $currentpage) {
         // 'highlight' it but don't make a link
         echo " [<b>$x</b>] ";
      // if not current page...
      } else {
         // make it a link
         echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$x'>$x</a> ";
      } // end else
   } // end if 
} // end for

结果：

For page 1: [1] 2 3 4 5 > >>
For page 3: 1 2 [3] 4 5 > >>
For page 5: << < 3 4 [5] 6 7 > >>
For page 6: << < 4 5 [6] 7 8 > >>
For page 10: << < 8 9 [10] 11 12 > >>
For last page 12: << < 8 9 10 11[12]

我还是想喜欢。。

For page 1: [1] 2 3 4 5 > >>
For page 3: 1 2 [3] 4 5 > >>
For page 5: 1 2 3 4 [5] > >>
For page 6: << < [6] 7 8 9 10 > >>
For page 10: << < 6 7 8 9 [10] > >>
For last page 12: << < 8 9 10 11[12]
