laravel 图片上传和删除

记录一下过程,使用php原生的方法,上传图片后把图片的路径存储到了数据库。

$file =$request->file('pic');
$allowed_extensions = ["png","jpg","jpeg"];
if ($file->getClientOriginalExtension() && !in_array($file->getClientOriginalExtension(), $allowed_extensions)) {
    return redirect()->back()->withInput()->withErrors("只允许上传.jpg .png .jpeg");
}
$path = 'storage/uploads/runner/';
$extension = $file->getClientOriginalExtension();
$fileName = str_random(10).'.'.$extension;
$file->move($path,$fileName);
$filePath = asset($path.$fileName);
$runner->pic = $filePath;

在删除的时候使用php的unlink("$path")方法,这里要注意的是 $path是laravel下public目录后的相对路径,需要对字符串进行拼接。

$path = $runner->pic;
$pos = strpos($path, 'storage');
/*dd($pos);*/
$path = substr($path,$pos,strlen($path));
unlink("$path");
