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
$url=$zbp->path."imgs/"; $img_array= glob($url."*.jpg",GLOB_BRACE); $num = array_rand($img_array); $filename=$img_array[$num]; echo $filename;
2、制作转移函数
function tc_imgssize_getSaveFileDir($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
$va1= str_replace($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
$imgurl = $zbp->host . 'zb_users/upload/' . date('Y', $times) . '/' . date('m', $times)."/".$fileName;
echo $imgurl;
