Zend Framework中insert时是组合的?我的sql一直有问题。supportsParameters是什么意思?
我在Controller中:
$table = new Model_Users();
$dd = array('username'=>$username,'password'=>md5($password),'name'=>$name,'email'=>$email,
'reg_time'=>date("Y-m-d H:m:s",time()),'ipaddr'=>$_SERVER['REMOTE_ADDR']);
$test = $table->insert($dd);
然后一直有错误,我跟踪后发现在zend_db_adapter_abstract 中的public function insert($table, array $bind) 中我的sql
在$this->supportsParameters('positional') 时全部把表中的值设为了“?”,请问这个函数的意思是什么?
是不是数据库的配置的问题?
代码:zend_db_adapter_abstract 中549cell.
------解决方案--------------------
你先查看 $this->supportsParameters('positional') 返回的值
最好贴出了来
再检查你准备赋值的变量是否与 ? 个数一致,赋值时的变量名是否与对应的字段名一致
------解决方案--------------------
1.根据你的Db Adapter, ZendDB有可能是调用了mysqli 或者 pdo mysql, 这两个扩展里都有bind操作的函数,然后代码就运行到了该函数的c部分啊
2.不是error-log,是mysql的log, 一般来说my.cnf里可能没有开启,

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
