打開/include/extend.func.php文件
在最下面加入
<span style="font-size:14px;">//文章body優(yōu)化替換
        function replaceurl($newurl)
        {
        global $dsql,$id;
        //獲取圖片附加表imgurls字段內(nèi)容進(jìn)行處
        $row = $dsql->GetOne("SELECT title FROM dede_archives where id=$id");
        //替換圖片Alt為文檔標(biāo)題
        $newurl=str_ireplace(array('alt=""','alt=\'\''),'',$newurl);
        $newurl=preg_replace("@ [\s]{0,}alt[\s]{0,}=[\"'\s]{0,}[\s\S]{0,}[\"'\s] @isU"," ",$newurl);
        $newurl=str_ireplace("<img " ,"<img  alt=\"".$row['title']."\"",$newurl);
        //去掉結(jié)尾空格
        $newurl=str_ireplace(" /","/",$newurl);
        $newurl=str_ireplace(" />","/>",$newurl);
        return $newurl;
        }</span>
  • 前段調(diào)用代碼
{dede:field.body function='replaceurl(@me)'/}
需要圖片中的style width height屬性就把上面代碼修改成下面的代碼
<span style="font-size:14px;">//文章body優(yōu)化替換
    function replaceurl($newurl)
     {
    global $dsql,$id;
    //獲取圖片附加表imgurls字段內(nèi)容進(jìn)行處
    $row = $dsql->GetOne("SELECT title FROM dede_archives where id=$id");
    //去掉img的width和height
    $newurl=preg_replace('/style=\"width\:(.*)\"/','',$newurl);
    //替換圖片Alt為文檔標(biāo)題
    $newurl=str_ireplace(array('alt=""','alt=\'\''),'',$newurl);
    $newurl=preg_replace("@ [\s]{0,}alt[\s]{0,}=[\"'\s]{0,}[\s\S]{0,}[\"'\s] @isU"," ",$newurl);
    $newurl=str_ireplace("<img " ,"<img  alt=\"".$row['title']."\"",$newurl);
    //去掉結(jié)尾空格
    $newurl=str_ireplace(" /","/",$newurl);
    $newurl=str_ireplace(" />","/>",$newurl);
    return $newurl;
     }</span>
