ThinkPHP整合Smarty模板引擎的使用以及查询方法汇总

其实说到整合smarty我们根本就没有作什么,要做的主要还是对于模板分配各种变量的使用,这才是重点,其次还有一些配置信息要自己去填写;先说一下配置,同样的,在主目录的common下面的config文件,把配置信息写入里面就可以了,其中主要有下面一下的配置信息。

'TMPL_ENGINE_TYPE'      =>  'Smarty',
//'TMPL_L_DELIM'          =>  '    //'TMPL_R_DELIM'          =>  '}>',            // 模板引擎普通标签结束标记
    //上面两个配置不太好使
    //如果出现冲突用{literal}{/literal}包起来,说明不解析这里面的模板

利用上面的信息就可以直接使用smarty模板引擎了,至于注意的方面,在注释里面都有说明。



不多说了,说说一下select方法,这个方法就是为数据库查询而生的。单纯的使用select方法就是取出所有的数据,但是,我们在很多的时候不需要浪费这个大的资源,所以,要结合一些查询条件才能更让select更好的发挥。

1:结合字段查询field:

$t=D('User');
// $info=$t->select();
$info=$t->field("name")->select();
$this->assign('info',$info);
$this->display();

这样我们取到的就只有name值。

2;group分组查询,$info=$t->field("name")->group('name')->select();

3:排序查询:$info=$t->order("字段")->select();升序查询。

4:也可以去选择数据表$info=$t->table('表名')->order("字段")->select();

5:limit:限制查询条数。

6:直接查询主键select("主键值1,主键值2");

7:find:返回一维数组的结果find('主键值');

8:having:在只有select查询到的情况下才能使用。

顺便还有一些聚合函数:sum,count,max,avg等是直接操作数据对象的。
