typecho网站实现阅读时间，平均阅读时长及字数统计的教程

阅读时间统计

实例代码：放到 functions.php 文件里面

//文章阅读时间统计
function art_time ($cid){
    $db=Typecho_Db::get ();
    $rs=$db->fetchRow ($db->select ('table.contents.text')->from ('table.contents')->where ('table.contents.cid=?',$cid)->order ('table.contents.cid',Typecho_Db::SORT_ASC)->limit (1));
    $text = preg_replace("/[^\x{4e00}-\x{9fa5}]/u", "", $rs['text']);
    $text_word = mb_strlen($text,'utf-8');
    echo ceil($text_word / 400);
}

使用

在需要显示地方插入以下代码

//获取代码为
阅读时长 ≈ <?php echo art_time($this->cid); ?>分钟

文章字数统计

把代码找个好的位置放好 functions.php 文件里面

//文章字数统计
function  art_count ($cid){
    $db=Typecho_Db::get ();
    $rs=$db->fetchRow ($db->select ('table.contents.text')->from ('table.contents')->where ('table.contents.cid=?',$cid)->order ('table.contents.cid',Typecho_Db::SORT_ASC)->limit (1));
    $text = preg_replace("/[^\x{4e00}-\x{9fa5}]/u", "", $rs['text']);
    echo mb_strlen($text,'UTF-8');
}

使用

在需要的地方调用

<?php art_count($this->cid); ?> 字数

Joe主题使用

1、修改function.php文件

在function.php文件的底部增加，文件路径：/usr/themes/Joe

// 文章阅读时长设置
$onlineTime = new Typecho_Widget_Helper_Form_Element_Select(
    'onlineTime',
    array(
        'off' => '关闭（默认）',
        'on' => '开启',
    ),
    'on',
    '是否启用文章阅读时长统计',
    '介绍：开启后，文章底部展示文章字数，预计阅读时长和已阅读时长'
);
$onlineTime->setAttribute('class', 'joe_content joe_custom'); //如果设置无法展示，请将joe_custom替换为joe_other
$form->addInput($onlineTime->multiMode());

2、修改article.php文件

在article.php文件，文件路径：usr/themes/Joe/public

图1处新增

<div class="contain" style="margin-bottom: 10px; <?php if(Helper::options()->onlineTime !== 'on') echo 'display:none;'  ?>">
    <blockquote id="onlineTime">本文共 <?php art_count($this->cid); ?> 个字数,平均阅读时长 ≈ <?php echo art_time($this->cid); ?>分钟</blockquote>
</div>

图2处新增，最底部

<?php 
//文章阅读时间统计
function art_time ($cid){
    $db=Typecho_Db::get ();
    $rs=$db->fetchRow ($db->select ('table.contents.text')->from ('table.contents')->where ('table.contents.cid=?',$cid)->order ('table.contents.cid',Typecho_Db::SORT_ASC)->limit (1));
    $text = preg_replace("/[^\x{4e00}-\x{9fa5}]/u", "", $rs['text']);
    $text_word = mb_strlen($text,'utf-8');
    echo ceil($text_word / 400);
}

//文章字数统计
function  art_count ($cid){
    $db=Typecho_Db::get ();
    $rs=$db->fetchRow ($db->select ('table.contents.text')->from ('table.contents')->where ('table.contents.cid=?',$cid)->order ('table.contents.cid',Typecho_Db::SORT_ASC)->limit (1));
    $text = preg_replace("/[^\x{4e00}-\x{9fa5}]/u", "", $rs['text']);
    echo mb_strlen($text,'UTF-8');
}
?>
<script language="javascript">
    var second=0;
    var minute=0;
    var hour=0;
    window.setTimeout("interval();",1000);
    function interval()
    {
        second++;
        if(second==60)
        {
            second=0;minute+=1;
        }
        if(minute==60)
        {
            minute=0;hour+=1;
        }
        var onlineTime = "您已阅读：" + hour + "时" + minute + "分" + second + "秒。";
        var joe_message_content = "本文共 " + <?php art_count($this->cid); ?> + "个字数，平均阅读时长 ≈ " + <?php echo art_time($this->cid); ?> + "分钟，";
        $('#onlineTime').text(joe_message_content + onlineTime);
        window.setTimeout("interval();", 1000);
    }
</script>
