[英]php pagination display 5pages range
我使用本教程使用分頁。
一切都很好,但我想改變頁碼的顯示。
教程代碼生成頁面鏈接如下。
For page 1 : [1] 2 3 4 > >>
For page 6 : << < 3 4 5 [6] 7 8 9 > >> ( 3 pages range before and after).
我想要改變的只是顯示5頁。
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] > >>
我認為這部分需要改變。 我試圖搜索其他文章,但我找不到任何。 什么是改變的好邏輯? 謝謝。
// 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'>$x</a> ";
} // end else
} // end if
} // end for
添加:
最后一頁也有5頁格式
For page 1: [1] 2 3 4 5 > >>
For page 3: 1 2 [3] 4 5 > >>
For page 5: 1 2 3 4 [5] > >>
For page 6: << < [6] 7 8 9 10 > >>
For page 10: << < 6 7 8 9 [10] > >>
For last page 12: << < 8 9 10 11[12]
我試圖將5頁數字作為數組中的組,與in_array一起使用。 還沒有成功。
添加:
不知何故,我讓它工作......但當前頁面總是在中心,這不是我想要.. :(
// range of num links to show
//$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'>$x</a> ";
} // end else
} // end if
} // end for
結果:
For page 1: [1] 2 3 4 5 > >>
For page 3: 1 2 [3] 4 5 > >>
For page 5: << < 3 4 [5] 6 7 > >>
For page 6: << < 4 5 [6] 7 8 > >>
For page 10: << < 8 9 [10] 11 12 > >>
For last page 12: << < 8 9 10 11[12]
我還是想要..
For page 1: [1] 2 3 4 5 > >>
For page 3: 1 2 [3] 4 5 > >>
For page 5: 1 2 3 4 [5] > >>
For page 6: << < [6] 7 8 9 10 > >>
For page 10: << < 6 7 8 9 [10] > >>
For last page 12: << < 8 9 10 11[12]
// loop to show links to range of pages around current page
for ($x = 1; $x <= ($totalpages); $x++) {
// if it's a valid page number...
if (($x > 0) && ($x <= $totalpages)) {
//limit for each 5 pages
if ($x % 5 == 0) {
// 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
