Thinkphp3.2.x 多图上传几个注意点
1、<form enctype="multipart/form-data">
2、<form enctype="multipart/form-data">
3、<input type="file" name="upload_pic[]" multiple>
4、$upload->upload(array($_FILES['upload_pic'])); 或 $upload->upload($_FILES); 否则会出现“非法上传对象”
5、上传配置 $config=array('saveName' => array('uniqid','')); 否则会引起重名覆盖
6.可以选择把上传数组转换为单个文件状态，然后进行单个判断上传
if ($_FILES['file']['name']!=''){
$covers=$_FILES['cover'];
foreach ($covers as $key=>$val){
foreach ($val as $m=>$n){
$cover[$m][$key]=$n;
}
}
foreach ($cover as $k=>$v){
$con['md5'] = md5_file($v['tmp_name']);
$con['sha1'] = sha1_file($v['tmp_name']);
$con['size'] = $v['size'];
$check = D('PublicUpload')->where($con)->find();
if (empty($check)){
$upload=new \Think\Upload();
$info=$upload->upload(array($v));
$info=$info[0];
$upload_data['type'] = $info["type"];
$upload_data['name'] = $info["name"];
$upload_data['path'] = '/Uploads/' . $info['savepath'] . $info['savename'];
$upload_data['url'] = $info["url"] ? : '';
$upload_data['ext'] = $info["ext"];
$upload_data['size'] = $info["size"];
$upload_data['md5'] = $info['md5'];
$upload_data['sha1'] = $info['sha1'];
$upload_data['location'] = 'Local';
$result = D('PublicUpload')->create($upload_data);
$result = D('PublicUpload')->add($result);
$c[]=$upload_data['path'];
}else{
$c[]=$check['path'];
}
}
$_POST['cover']=implode(';',$c);
}
