jquery-file-upload 的php mysql插入问题
https://github.com/blueimp/jQuery-File-Upload/wiki/PHP-MySQL-database-integration
上传时按照他的参考文档,立马就完成了,一开始也按照他的sql 架构先试试
结果上传后,也能成功插入,json传回页面一切正常!
但问题来了,他的sql 架构...有个叫url
但作者好像在PHP的SQL中没有处理
那我就改改吧,....
先新增了一些基本配置
$dir = $_COOKIE["uid"].'/'.date("Y").'/'.date("m").'/'.date("d").'/';$dirUP = "../../../att/".$dir;$dirLink = $dir;$options=array( 'upload_dir' => $dirUP, 'upload_url' => $dirLink, 'delete_type' => 'POST', 'db_host' => 'localhost', 'db_user' => 'root', 'db_pass' => '*****', 'db_name' => '*****', 'db_table' => 'files');
应该就是这段了....
我尝试多次,加入url字段都不成功 [原本的文档代码]
protected function handle_file_upload($uploaded_file, $name, $size, $type, $error, $index = null, $content_range = null) { $file = parent::handle_file_upload( $uploaded_file, $name, $size, $type, $error, $index, $content_range ); if (empty($file->error)) { $sql = 'INSERT INTO `'.$this->options['db_table'] .'` (`name`, `size`, `type`, `title`, `description`)' .' VALUES (?, ?, ?, ? , ?)'; $query = $this->db->prepare($sql); $query->bind_param( 'sisss', $file->name, $file->size, $file->type, $file->title, $file->description ); $query->execute(); $file->id = $this->db->insert_id; } return $file; }
都给我显示:
Warning: mysqli_stmt::bind_param(): Number of elements in type definition string doesn't match number of bind variables in
这是什么意思,说我的数量有问题? 是指我加少了吗?
我已经改成...这样,5处的type字段也都加了url也说是数量问题?
protected function handle_file_upload($uploaded_file, $name, $size, $type,$url, $error, $index = null, $content_range = null) { $file = parent::handle_file_upload( $uploaded_file, $name, $size, $type,$url, $error, $index, $content_range ); if (empty($file->error)) { $sql = 'INSERT INTO `'.$this->options['db_table'] .'` (`name`, `size`, `type`, `url`, `title`, `description`)' .' VALUES (?, ?, ?, ?,? , ?)'; $query = $this->db->prepare($sql); $query->bind_param( 'sisss', $file->name, $file->size, $file->type, $file->url, $file->title, $file->description ); $query->execute(); $file->id = $this->db->insert_id; } return $file; }
我需要保存成
$url = $_COOKIE["uid"].'/'.date("Y").'/'.date("m").'/'.date("d").'/'. filename
要怎么改? 直接用$file->url就可以吗?
另外...因为这玩意,还弄到一个append取值问题,熟jq的朋友也可以去这帮帮小弟吧

回复讨论(解决方案)
警告:mysqli_stmt::bind_param():在类型定义字符串不匹配的绑定变量的元素个数
这还不清楚吗?
$query->bind_param(
' sisss', //怎么只有 5 个类型声明?
$file->name, //1
$file->size, //2
$file->type, //3
$file->url, //4
$file->title,//5
$file->description //6 共6个
);

喔...原来这个问题
已成功解决了!
以前用完mysql_query后就转用pdo了,没用过mysqli,PDO好像就没怎么提过这写法
谢谢,学习了
