The thinkphp form uploads a file and saves the file path to the database,

Upload a single file. The upload effect is as follows:

Create a database upload_img to save the upload path

Create table 'seminar _ upload_img '(
'Id' int (11) not null AUTO_INCREMENT,
'Img _ name' varchar (255) default null comment 'image name ',
'Img _ url' varchar (255) default null comment 'image path ',
'Create _ time' text,
Primary key ('id ')
) ENGINE = InnoDB AUTO_INCREMENT = 23 default charset = utf8;
Connect to the database in the Common/Conf. php file and configure the address.

Return array ('db _ type' => 'mysql', 'db _ host' => '127. 0.0.1 ', 'db _ name' => 'seminar', 'db _ user' => 'root', 'db _ pwd' => 'root ', 'db _ port' => 3306, 'db _ prefix' => 'seminar _ ', 'db _ CHARSET' => 'utf8 ', 'Show _ PAGE_TRACE '=> true,/* address replacement */'tmpl _ PARSE_STRING' => array ('_ UPLOAD _' = >__ ROOT __. '/Public/Uploads ',),);
