thinkphp Study Notes (v) data validation

According to the official website of the tutorial (http://www.thinkphp.cn/info/171.html), data validation using a static definition (in the case of regex) cannot validate the data:

Dynamic validation is normal:

Controller:

<?PHPclassIndexactionextendsAction { Public functionAdd () {$ARTICLEOBJ= D ("article"); $rules=Array(            Array(' title ', ' Require ', ' please fill in the title '),        ); if(!$ARTICLEOBJ->validate ($rules),Create ()) {             //If the creation fails, the validation does not pass the output error message             Exit($ARTICLEOBJ-GetError ()); }Else{             $ARTICLEOBJ->add_time =Date("Y-m-d h:i:s", Time()); if($ARTICLEOBJ-Add ()) {                $this->success ("Data added successfully"); }Else{                $this->error ("Data addition failed"); }         }        }}
