分享ThinkPHP3.2中关联查询解决思路_php实例
不废话了,直接给大家贴代码了,代码很简单,都是比较常见的sql语句,具体内容请看下文。
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
怎样在模型中建立关联?
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 . '%'));

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security.
