lumen 支持多文件上传及php 原生多文件上传
1、webform (注意:name后面一定要加[]号)
<form method="post" enctype="multipart/form-data" action="http://127.0.0.1/mobile/public/api/wx/user/upload" >
First name: <input type="file" name="file[]" /><br />
First name: <input type="file" name="file[]" /><br />
Last name: <input type="text" name="token" /><br />
<input type="submit" value="提交" />
</form>
注:HTML5的文件已经支持多文件上传:
<input type="file" name="file[]" multiple/>
2、后端处理
1 /*上传文件到服务器*/ 2 public function uploadFile(\Illuminate\Http\Request $request) 3 { 4 5 $this->validate($request,array('token'=>'required|string')); 6 $this->validationUser($uid,$this->authService); 7 if($request->hasFile('file')) { 8 $root = $request->server('DOCUMENT_ROOT'); 9 $file = $request->file('file'); 10 //return var_dump($file); 11 $filePath=[]; // 定义空数组用来存放图片路径 12 foreach ($file as $k => $v) { 13 // 判断图片上传中是否出错 14 if (!$v->isValid()) { 15 $this->apiReturn("上传图片出错,请重试!",1); 16 } 17 //此处防止没有多文件上传的情况 18 if(!empty($v)){ 19 if ($v->getSize() / 1024 > 600) 20 return $this->apiReturn("请检查您上传的文件不能大于600KB", 1); 21 $fileName = strtolower($v->getClientOriginalName()); 22 if (!preg_match('/\.(jpg|jpeg|png|gif)$/', $fileName)) 23 return $this->apiReturn("您只能上传通用的图片格式", 1); 24 $destinationPath = '/mobile/resources/uploads/' . date('Ymd'); 25 $fileExtendName = substr($fileName, strpos($fileName, '.')); 26 $realPath = $root . $destinationPath; 27 if (!file_exists($realPath)) 28 mkdir($realPath); 29 $newFileName = uniqid() . mt_rand(1, 100000) . $fileExtendName; 30 $v->move($realPath, $newFileName); 31 $filePath[]=$destinationPath . '/' . $newFileName; 32 }} 33 return $this->apiReturn(json_encode($filePath), 0); 34 } 35 else 36 return $this->apiReturn('请选择文件再上传', 1); 37 }
原生多文件上传:
/*多文件上传*/
public function uploadImg($file_name,$dir,$format='string')
{
$file = $_FILES[$file_name];
if($file) {
$root =$_SERVER['DOCUMENT_ROOT'];
$filePath=[]; // 定义空数组用来存放图片路径
$fileNumber=count($file['name']);
for($i=0;$i<$fileNumber;$i++) {
//此处防止没有多文件上传的情况
if(!empty($file['name'][$i])){
if ($file['size'][$i] / 1024 > 600)
{
return ['error'=>"请检查您上传的文件不能大于600KB"];
}
$fileName = strtolower($file['name'][$i]);
if (!preg_match('/\.(jpg|jpeg|png|gif)$/', $fileName))
{
return ['error'=>'您只能上传通用的图片格式'];
}
$destinationPath = $dir. date('Ymd');
$fileExtendName = substr($fileName, strpos($fileName, '.'));
$realPath = $root . $destinationPath;
if (!file_exists($realPath))
{
make_dir($realPath);
}
$newFileName = uniqid() . mt_rand(1, 100000) . $fileExtendName;
move_uploaded_file($file['tmp_name'][$i], $realPath.'/'.$newFileName);
$filePath[]=$destinationPath . '/' . $newFileName; }
}
if($format=='string')
return implode(',',$filePath);
}
else
return ['error'=>'请选择文件再上传'];
}
