突出显示当前页码PHP分页 [英] Highlight Current page number PHP Pagination

问题描述

我在解决此问题时遇到问题，因此我需要更专业的解决方案.我的产品列表中有分页设置.问题是当我切换页面时，编号上的活动班级没有显示或显示有误.例如，当用户单击2(第2页)时，它显示项目的第二页，而突出显示的是5.需要帮助解决此问题，以突出显示当前正在查看的页面.

I'm having problems resolving this so I'm asking for more professional solutions. I have pagination setup for my list of products. Problem is when I switch pages, the active class on the number is not showing or showing wrongly. For example, when users click on 2 (Page 2), it displays the 2nd page of items, but 5 is the one highlighted. Need help fixing this up to highlight the currently being viewed page.

此代码用于设置偏移量.

This code is for setting the offset.

$totalrows = db_getvalue("select count(buyinfo_id) from buyinfo,user $addtable where buyinfo.user_id=user.user_id $clause $orderbyclause", $global_connection);
        if ($totalrows == "")
            $totalrows = 0;
        $totalpages = ceil($totalrows/$listcount);
        if ($totalpages > 1) {
            $curpageoffset = 0;
            if (isset($_REQUEST['offset'])) {
                if ($_REQUEST['offset'] >= $totalpages)
                    $curpageoffset = $totalpages - 1;
                else if ($_REQUEST['offset']>0)
                    $curpageoffset = $_REQUEST['offset']*$listcount-1;
            }
            $limitstr = " limit $curpageoffset,$listcount";
        }

例如，当我转到第3页时，它将显示www.site.com/?offset=2

When I go to Page 3 for example, it displays www.site.com/?offset=2

我猜这是因为$ curpageoffset = $ _REQUEST ['offset'] * $ listcount-1; -1;

I guess its because of the -1 in $curpageoffset = $_REQUEST['offset']*$listcount-1;

这是负责页码的代码:

<?php
    if ($totalpages>1) {
            echo "<tr><td><ul class='pagination'>";
            echo "<li><a href='' aria-label='Previous' ";
            if ($curpageoffset == 0) {
                echo "onclick='return false;'";
            } else {
                echo "onclick='util_reload(\"posts/?offset=".($curpageoffset-1)."$pageparam\"); return false;'";
            }
            echo " ><span aria-hidden='true'>&laquo;</span></a></li>";

            $tmpctr = 0;
            while ($tmpctr < $totalpages) {
                $curstyle = "";
                if ($tmpctr == $curpageoffset)
                    $curstyle = "class='active'";

                echo "<li $curstyle><a href='' onclick='util_reload(\"posts/?offset=$tmpctr$pageparam\"); return false;'>";
                $tmpctr++;
                echo "$tmpctr</a></li>";
            }

            echo "<li><a href='' aria-label='Next' ";
            if ($curpageoffset >= $totalpages-1) {
                echo "onclick='return false;'";
            } else {
                echo "onclick='util_reload(\"posts/?offset=".($curpageoffset+1)."$pageparam\"); return false;'";
            }
            echo " ><span aria-hidden='true'>&raquo;</span></a></li>";

            echo "</ul></td></tr>";
    }
?>

推荐答案

由于您已设置了curpageoffset的值以供查询使用，因此您无法在分页代码中使用它来突出显示当前所在的页面...我将以这种方式更改您的代码..使用原始的$ _REQUEST ['offset']，因为这实际上是页码.

Since you've set the value of curpageoffset for use in your query, you can't use it in your pagination code to highlight the page you're on ... I would change your code this way .. using the original $_REQUEST['offset'] since that's essentially the page number.

while ($tmpctr < $totalpages) {
                $curstyle = "";
                if ($tmpctr == $_REQUEST['offset'])
                    $curstyle = "class='active'";

                echo "<li $curstyle><a href='' onclick='util_reload(\"posts/?offset=$tmpctr$pageparam\"); return false;'>";
                $tmpctr++;
                echo "$tmpctr</a></li>";
            }
