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> {:__('Upload')}</button></span>
                <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
     */
    '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
找到文件上传的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 = $this->request->file('file');
        if (empty($file)) {
            $this->error(__('No file upload or server upload limit exceeded'));
        }
        //判断是否已经存在附件
        $sha1 = $file->hash();
        $upload = Config::get('upload');
        preg_match('/(d+)(w+)/', $upload['maxsize'], $matches);
        $type = strtolower($matches[2]);
        $typeDict = ['b' => 0, 'k' => 1, 'kb' => 1, 'm' => 2, 'mb' => 2, 'gb' => 3, 'g' => 3];
        $size = (int)$upload['maxsize'] * pow(1024, isset($typeDict[$type]) ? $typeDict[$type] : 0);
        $fileInfo = $file->getInfo();
        $suffix = strtolower(pathinfo($fileInfo['name'], PATHINFO_EXTENSION));
        $suffix = $suffix ? $suffix : 'file';
        $mimetypeArr = explode(',', strtolower($upload['mimetype']));
        $mimetypeArr=array_merge($mimetypeArr,['mp4','mp3','avi','flv','wmv']);
        $typeArr = explode('/', $fileInfo['type']);
        //验证文件后缀
        if ($upload['mimetype'] !== '*' &&
            (
                !in_array($suffix, $mimetypeArr)
                || (stripos($typeArr[0] . '/', $upload['mimetype']) !== false && (!in_array($fileInfo['type'], $mimetypeArr) && !in_array($typeArr[0] . '/*', $mimetypeArr)))
            )
        ) {
            //dump(123456);die;
            $this->error(__('Uploaded file format is limited'));
        }
        $replaceArr = [
            '{year}'     => date("Y"),

            if (in_array($suffix, ['gif', 'jpg', 'jpeg', 'bmp', 'png', 'swf', 'mp4', 'mp3'])) {
