Question

以下代码是我的表的php分页，它正在正确加载结果，但问题是，当我点击下一页时，它将重复包含在第一页中的相同值。结果不会改变。我无法找到它的错误？

paginate.php

function paginate($reload, $page, $tpages) {
$adjacents = 10;
$prevlabel = "&lsaquo; Prev";
$nextlabel = "Next &rsaquo;";
$out = "";
// previous

if ($page <= 1) {
    $out.= "<span style='font-size:14px; float:left; padding:5px;'>" . $prevlabel . "</span>\n";
} else {
    $out.= "<li><a  href=\"" . $reload . "&amp;page=" . ($page - 1) . "\">" . $prevlabel . "</a>\n</li>";
}

$pmin = ($page > $adjacents) ? ($page - $adjacents) : 1;
$pmax = ($page < ($tpages - $adjacents)) ? ($page + $adjacents) : $tpages;
for ($i = $pmin; $i <= $pmax; $i++) {
    if ($i == $page) {
        $out.= "<li  class=\"active\"><a href=''>" . $i . "</a></li>\n";
    } elseif ($i == 1) {
        $out.= "<li><a  href=\"" . $reload . "\">" . $i . "</a>\n</li>";
    } else {
        $out.= "<li><a  href=\"" . $reload . "&amp;page=" . $i . "\">" . $i . "</a>\n</li>";
    }
}

if ($page < ($tpages - $adjacents)) {
    $out.= "<span style='font-size:14px; padding:10px;'>
    <a style='font-size:14px' href=\"" . $reload . "&amp;page=" . $tpages . "\">" . $tpages . " "."Pages"."</a></span>\n";
}
// next
if ($page < $tpages) {
    $out.= "<li><a  href=\"" . $reload . "&amp;page=" . ($page + 1) . "\">" . $nextlabel . "</a>\n</li>";
} else {
    $out.= "<span style='font-size:14px; float:left; padding:5px;'>" . $nextlabel . "</span>\n";
}
$out.= "";
return $out;

请帮忙！

我没有跟踪所有代码，但我注意到你的if-else无论如何设置$page = 1。

if ($page <= 0) {
  $page = 1;
} else {
  $page = 1;
  $tpages = $total_pages;
}

PHP分页不适用于表的第二页
