fastadmin上传⽂件失败提⽰格式错误
1.
⾸先在数据表中建⽴以file为后缀的视频字段名；
在html的上传按钮中，添加两个属性data-mimetype=”mp3,mp4,avi,flv,wmv”等等视频类型属性和data-maxsize=”100M”即视频⼤⼩的最⼤值；如：
<div class="form-group">
<label class="control-label col-xs-12 col-sm-2">{:__('Vediofile')}:</label>
<div class="col-xs-12 col-sm-8">
<div class="input-group">
<input id="c-vediofile" class="form-control" size="50" name="row[vediofile]" type="text">
<div class="input-group-addon no-border no-padding">
<span><button type="button" id="plupload-vediofile" class="btn btn-danger plupload" data-input-id="c-vediofile" data-mimetype="mp4,mp3,avi,flv,wmv" data-multiple="false" data-maxsize="50M"><i class="fa fa-upload"></i> {:__('Uplo                <span><button type="button" id="fachoose-vediofile" class="btn btn-primary fachoose" data-input-id="c-vediofile" data-mimetype="mp4,mp3,avi,flv,wmv" data-multiple="false"><i class="fa fa-list"></i> {:__('Choose')}</button></span>            </div>
<span class="msg-box n-right" for="c-vediofile"></span>
</div>
</div>
</div>
2.修改application/extra/upload.php中的maxsize配置：
<?php
//上传配置
return [
// ....
/**
* 最⼤可上传⼤⼩inputtypefile不上传文件
*/
'maxsize'  => '50mb',
/**
* 可上传的⽂件类型(新增mp4,mp3,avi,flv,wmv视频⽂件后缀)
*/
'mimetype'  => 'jpg,png,bmp,jpeg,gif,zip,rar,xls,xlsx,mp4,mp3,avi,flv,wmv',
// ....
];
>
//////我的后台修改过后⽂件样式：：：
<?php
//上传配置
return [
/**
* 上传地址，默认是本地上传
*/
'uploadurl' => 'ajax/upload',
/**
* CDN地址
*/
'cdnurl'    => '',
/**
* ⽂件保存格式
*/
'savekey'  => '/uploads/{year}{mon}{day}/{filemd5}{.suffix}',
/**
* 最⼤可上传⼤⼩
*/
'maxsize'  => '50mb',
/**
* 可上传的⽂件类型
*/
'mimetype'  => 'jpg,png,bmp,jpeg,gif,zip,rar,xls,xlsx,mp4,mp3',
/**
* 是否⽀持批量上传
*/
'multiple'  => false,
];
>
3.修改php.ini配置⽂件后，并重新启动php：
a、 file_uploads = On ；是否允许通过HTTP上传⽂件的开关。默认为On即是开
b、upload_tmp_dir ;⽂件上传⾄服务器上存储临时⽂件的地⽅，如果没指定就会⽤系统默认的临时⽂件夹
c、upload_max_filesize = 8M ；望⽂⽣意，即允许上传⽂件⼤⼩的最⼤值。默认为2M
d、post_max_size = 8M ；指通过表单POST给PHP的所能接收的最⼤值，包括表单⾥的所有值。默认为8M
到⽂件上传的php，在application/admin/controller/Ajax.php，修改⾥⾯的upload⽅法，在此基础上添加视频上传的代码即可
<?php
/**
* 上传⽂件
*/
public function upload()
{
//dump(123);die;
Config::set('default_return_type', 'json');
$file = $this->request->file('file');
