[英] How to Integrate Blue Imp File Upload to CakePHP?
本文介绍了如何将 Blue Imp 文件上传集成到 CakePHP?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
Wa 正在使用 CakePHP，需要集成 Blue Imp 文件上传库.有没有人成功集成这些?如果是这样，您是否设置了上传以将文件存储在数据库或文件系统上?您能否分享此类集成的示例?
非常感谢您的帮助和指导.
解决方案
是的，我在 php 中集成了 BlueImp 文件上传功能.请找到以下组件和要使用的元素.
options = array('script_url' =>$this->getFullUrl().'/','上传目录' =>目录名($_SERVER['SCRIPT_FILENAME']).'/attachments/files/','upload_url' =>$this->getFullUrl().'/files/','param_name' =>'文件',//将以下选项设置为POST"，如果您的服务器不支持//删除请求.这是发送给客户端的参数:'delete_type' =>'邮政'，//php.ini 设置upload_max_filesize 和post_max_size//优先于以下 max_file_size 设置:'max_file_size' =>空值，'min_file_size' =>1、'accept_file_types' =>'/.+$/i','max_number_of_files' =>空值，//将以下选项设置为 false 以启用可恢复上传:'discard_aborted_uploads' =>真的，//设置为 true 以根据 EXIF 元数据旋转图像(如果可用):'orient_image' =>错误的，'image_versions' =>大批(//取消注释以下版本以限制大小//上传的图片.您还可以添加其他版本//自己的上传目录:/*'大' =>大批('上传目录' =>目录名($_SERVER['SCRIPT_FILENAME']).'/files/','upload_url' =>$this->getFullUrl().'/files/','max_width' =>1920年，'max_height' =>1200,'jpeg_quality' =>95),*/'缩略图' =>大批('上传目录' =>dirname($_SERVER['SCRIPT_FILENAME']).'/attachments/thumbnails/','upload_url' =>$this->getFullUrl().'/attachments/thumbnails/','max_width' =>80,'max_height' =>80)));如果(is_array($options)){$this->options = array_replace_recursive($this->options, $options);}}受保护的函数 getFullUrl() {返回(isset($_SERVER['HTTPS']) ?

Wa are using CakePHP and need to integrate the Blue Imp file upload libraries. Has anyone successfully integrated these? If so, did you setup the upload to store files on the database or file system? Can you share examples of such an integration?
Thanks much for your help and guidance.

Yes I integrated the BlueImp file upload functionality in php. Please find the following component and the element to use.
