Question

我想知道是否有人可以在我的商店中帮我解决一些分页问题。使用pajinate，我最初把它放在一起，但它似乎被窃听。我想添加一个'previous'和'back to begin'以及'next'和'last page'按钮。我尝试先实现'回到开始'和'上一步'按钮，但它们无法正常工作。如果有人可以帮助我一点点太棒了。在旁注中，我将此设置为一次显示10个数字的范围，但每次我点击更高的页码时，它会附加4-5个数字，对此问题的任何见解都将非常受欢迎。

<?php
// find out total pages

$totalpages = $resp->paginationOutput->totalPages;
echo "Total Results: ";
echo $totalpages.' pages ';
// get the current page or set a default
if (isset($_GET['pgno']) && is_numeric($_GET['pgno'])) {
   // cast var as int
   $currentpage = (int) $_GET['pgno'];
} else {
   // default page num
   $currentpage = 1;
} // end if

// if current page is greater than total pages...
if ($currentpage > $totalpages) {
   // set current page to last page
   $currentpage = $totalpages;
} // end if
// if current page is less than first page...
if ($currentpage < 1) {
   // set current page to first page
   $currentpage = 1;
} // end if

// the offset of the list, based on current page
$offset = ($currentpage - 1) * $entriesPerPage;

/******  build the pagination links ******/
// if not on page 1, don't show back links
if ($currentpage > 1) {
   // show << link to go back to page 1
if(null!=$queryString){
//  echo " <a href='{$_SERVER['PHP_SELF']}?$queryString&currentpage=1'><<</a> ";
}else{
//  echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=1'><<</a> ";
}
   // get previous page num
 //  $prevpage = $currentpage - 1;
   // show < link to go back 1 page
//   echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$prevpage'><</a> ";
} // end if

// range of num links to show
$range = 10;

// 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 == $currentpage) {
         // 'highlight' it but don't make a link
         echo " [<strong>$x</strong>] ";
      // if not current page...
      } else {
         // make it a link
         echo " <a href='".add_url_param('pgno',$x)."'>$x</a> ";

      } // end else
   } // end if
} // end for
?>

你的prev页面被注释掉了，使用$ _GET ['currentpage']而不是$ _GET ['pgno']，这对我有用：

<?
$totalpages = 10;
if (isset($_GET['pgno']) && is_numeric($_GET['pgno'])) {
// cast var as int
$currentpage = (int) $_GET['pgno'];
} else {
// default page num
$currentpage = 1;
} // end if

echo $currentpage;
echo "/".$totalpages;
echo "<br />";

// if current page is greater than total pages...
if ($currentpage > $totalpages) {
// set current page to last page
$currentpage = $totalpages;
} // end if
 // if current page is less than first page...
if ($currentpage < 1) {
 // set current page to first page
 $currentpage = 1;
}   // end if

// the offset of the list, based on current page
$offset = ($currentpage - 1) * $entriesPerPage;

/******  build the pagination links ******/
// if not on page 1, don't show back links
if ($currentpage > 1) {
// show << link to go back to page 1
if(null!=$queryString){
 echo " <a href='{$_SERVER['PHP_SELF']}?$queryString&pgno=1'><<</a> ";
}else{
  echo " <a href='{$_SERVER['PHP_SELF']}?pgno=1'><<</a> ";
}
// get previous page num
$prevpage = $currentpage - 1;
// show < link to go back 1 page
 echo " <a href='{$_SERVER['PHP_SELF']}?pgno=$prevpage'><</a> ";
} // end if

// range of num links to show
$range = 10;

// 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 == $currentpage) {
       // 'highlight' it but don't make a link
       echo " [<strong>$x</strong>] ";
    // if not current page...
    } else {
       // make it a link
       echo " <a href='".$_SERVER['PHP_SELF']."?pgno=$x"."'>$x</a> ";

     } // end else
   } // end if
 } // end for
 ?>
