PHP分页 - 限制链接数量

标签: php pagination hyperlink limit paging

所以我有这样的分页链接。

for ( $counter = 0; $counter <= $page_amount; $counter += 1) {
        echo "<a href=\"section.php?q=$section&p=$counter\">";
        echo $counter+1;
        echo "</a>";
     }

链接增长如下:

1 2 3 4 5 6 7等等。

但是我想限制这个,所以如果超过7页,它只会显示7个这样的链接:

1 2 3 ... 10 11 12

其中12是最后一页。

如果你转到下一页,它只会改变这样的第一页:

3 4 5 ... 10 11 12

直到你达到这样的最后7页:

6 7 8 9 10 11 12

我该怎么做?

请帮忙。

这是一种方法。

// Set some presets
$current_page = 0;
$page_amount = 11;
$limiter = 7;

// Set upper and lower number of links
$sides = round(($limiter/2), 0, PHP_ROUND_HALF_DOWN);

for ( $counter = 0; $counter <= $page_amount; $counter++) {
    // Start with Current Page
    if($counter >= ($current_page)){
        // Show page links of upper and lower
        if(($counter <($current_page+$sides))||($counter >($page_amount-$sides))){
            echo "<a href=\"section.php?q=$section&p=$counter\">";
            echo $counter+1;
            echo "</a> ";
        }
        // The middle link
        elseif($counter ==($current_page+$sides)){
            echo "<a href=\"page.php?p=$counter\">";
                    // Show number if number of links == $limiter
            if(($page_amount-$current_page)==$limiter-1){
                 echo $counter+1;
            }
            // Show '...' number of links > $limiter 
                    else {
                     echo "...";
            }
            echo "</a> ";
        }
     }
}

这允许更改显示的链接数,即。从7到9。

注意,在PHP_ROUND_HALF_DOWN中使用round()需要php&gt; = 5.3
