eBay購物API分頁

Question

我想知道是否有人可以幫我解決一些分頁問題。使用pajinate，我最初把它放在一起，但它似乎被竊聽。我想添加「上一頁」和「回頁首」以及「下一頁」和「最後一頁」按鈕。我試着先執行'回到開始'和'上一個'按鈕，但他們不能正常工作。如果有人能夠幫助我一點，那就太棒了。在附註中，我設置了一次顯示10個數字的範圍，但每次點擊更高的頁碼時，它都會附加4-5個數字，對此問題的任何見解都將不勝感激。

<?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){

    // 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

你曾上一頁註釋掉，並使用$ _GET [ '當前第']而不是$ _GET [ 'PGNO']，這個工作對我來說：

<? 
$totalpages = 10; 
if (isset($_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 
?>

$offset = ($currentpage - 1) * $entriesPerPage; 


if ($currentpage > 1) { 

?where comes this variable
