CREATE TABLE `test_avatar` ( `uid` int (11) unsigned NOT NULL DEFAULT '0' , `avatar` varchar (255) NOT NULL DEFAULT '' , PRIMARY KEY (`uid`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8; INSERT INTO `test_avatar` VALUES (1, './Uploads/admin.jpg' ); CREATE TABLE `test_pro` ( `id` int (11) unsigned NOT NULL AUTO_INCREMENT, `uid` int (11) unsigned NOT NULL DEFAULT '0' , ` name ` varchar (255) NOT NULL DEFAULT '' , PRIMARY KEY (`id`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8; INSERT INTO `test_pro` VALUES (1,1, '产品1' ),(2,1, '产品2' ); CREATE TABLE `test_user` ( `id` int (11) unsigned NOT NULL AUTO_INCREMENT, `username` varchar (50) NOT NULL DEFAULT '' , `tel` int (11) unsigned NOT NULL DEFAULT '0' , PRIMARY KEY (`id`) ) ENGINE=MyISAM DEFAULT CHARSET=utf8; INSERT INTO `test_user` VALUES (1, 'admin' ,110); |
如上三个表:用户头像表、产品表、用户表

class ProModel extends RelationModel{ protected $_link=array( 'Avatar' =>array( 'mapping_type' =>self::HAS_ONE, 'class_name' => 'Avatar' , 'foreign_key' => 'uid' , 'mapping_fields' => 'avatar' , 'as_fields' => 'avatar' , ), ) } |
试过用HAS_ONE、BELONGS_TO、HAS_MANY、MANY_TO_MANY都不行,求大神指点
------解决思路----------------------
Model下建立ProModelModel.class.php

class ProModelModel extends ViewModel { public $viewFields = array( 'test_avatar' =>array( 'id' ,... ), 'test_pror' =>array( 'id' ,... '_on' => '' ), 'test_pror' =>array( 'id' ,... '_on' => '' ), ); } |
Thinkphp中SQL语句有关问题及解决办法
请问,在THINKPHP中,数据表里有个字段,字段的内容形式为 {1,2,3,4,5}
那么SQL语句里怎么将获得的ID值来跟字段里的内容来比较呢
------解决思路----------------------
用模糊查询吧

$ where = array( '该字段' =>array( 'LIKE' , '%' . $ID . '%' )); |
