Question

ThinkPHP3.2高手来一下 关于验证码.

Public function login(){
$code = I('code');
$id='';
$verify = new \Think\Verify();
if(! $verify->check($code, '')){
$this->error('验证码错误');
}
}
这样运行没有错;
可是下面就出错,为什么?
Public function check_verify($code, $id = ''){
$verify = new \Think\Verify();
return $verify->check($code, $id);
}
Public function login(){
$code = I('code');
$id='';
if(! check_verify($code, $id)){ //就这句出错
//提示Call to undefined function Admin\Controller\check_verify()
$this->error('验证码错误');
}
}

Answer 1

if(!check_verify($code, $id)) 改为if(!$this->check_verify($code, $id))
