Why does my TP framework accept post data without clicking submit?

Some of the guys said it was ispost wrong, and now we're going to send a look at what's on the manual.

Red Label 3 is a simple few lines of code, the red one is the method of the corresponding link

The problem is, my code is clearly written in the case of if (is_post), only echo that 11111, why the display page is displayed directly, Ah, should not be after I click the Submit button to appear?

Submit Address Yes

PHP section:

Class Bcastaction extends commonaction{

public function index(){

    $this->display();}

Public Function Insert () {

$this->display();

}

public function add(){

$IS _post=$_server[' request_method '] = = ' POST '? True:false;

    if($IS_POST){

Echo ' 111 ';d ie;
}

}

}
?>

That's all, I don't know what's wrong.

Should be
if (is_post)
{

echo 111;

}

Your tp version of 2.0 is not supported, IS_POST IS_GET This type of notation, tp the constant IS_POST , IS_GET and so on in the 3.1 version only. Since the wording does not support, you directly use the most primitive $_post, $_get can not? Finish the task first.
