zblog从文件夹中随机获取一张图片上传到附件并删除

本方案采用的是php语言，操作步骤如下：
1、从文件夹中随机抽取一张图片
点击复制代码 PHP
$url=$zbp->path."imgs/";
$img_array= glob($url."*.jpg",GLOB_BRACE);
$num = array_rand($img_array);
$filename=$img_array[$num];
echo $filename;
2、制作转移函数
点击复制代码 PHP
function tc_imgssize_getSaveFileDir($times, $fileName)
{
    global $zbp;
    $fileDirPath = $zbp->usersdir . 'upload/' . date('Y', $times) . '/' . date('m', $times);
    if (!file_exists($fileDirPath)) {
        @mkdir($fileDirPath, 0755, true);
    }
    return $fileDirPath . "/" . $fileName;
}
3、上传到附件
点击复制代码 PHP
$va1= str_replace($url, "", $fileName);
$vc=explode('.',$va1);
$suffix= $vc[1];
$size=filesize($fileName);
$times        = time(); //固定时间
$fileName     = date("YmdHis", $times) . $times . rand(10000, 99999) . '.' . $suffix;
$fileSavePath = tc_imgssize_getSaveFileDir($times, $fileName);
$upload             = new \Upload();
$upload->Name       = $fileName;
$upload->SourceName = $fileName;
$upload->MimeType   = "image/" . $suffix;
$upload->Size       = $size;
$upload->AuthorID   = 1;
rename($va, $fileSavePath);
$filepath = $fileSavePath;
$upload->Save();
4、获取新的图片地址
点击复制代码 PHP
$imgurl = $zbp->host . 'zb_users/upload/' . date('Y', $times) . '/' . date('m', $times)."/".$fileName;
echo $imgurl;
