ThinkPHP form automatic verification application example, thinkphp example
Using TP 3.2 framework
public function add_post(){ //验证规则 $rule=array( array('name','require','请输入姓名',1),//必须验证name ); $m=M('user'); //获取name,sex,contact数据到模型,并验证 if(!$m->field('name,sex,contact')->validate($rule)->create()) $this->error($m->getError()); $result=$m->add(); if(!$result) $this->error('添加失败'); $this->success('添加成功',U('dir')); }
Validation rules can also be written into the model, but I find it a bit troublesome. First, sometimes different pages have different verification methods. Second, when you see the code in the add_post event, you will know what data to receive and how. The verification data can give you a general understanding at first glance, so this method is summarized.
ThinkPHP’s backend framework does not have ajax itself. Just use jquery form to submit, it is very convenient. You can take a look at thinkphp’s official example

Let me show you an example I wrote:
//Form validation
protected $_validate=array(
//array('validation field','validation rule','error prompt', Verification conditions, additional rules, verification time)
array('uname','require','Username must be verified!',1,'regex',3),
//array('username', '','The username already exists',1,'unique',1),
array('pwd','require','The password must be filled in!'),
array('pwd ','checkPwd','Password length is not less than 6 characters',1,'callback'),
);
function checkPwd(){
$password=$_POST['pwd '];
if(strlen($password)>=6){
return true;
}else {
return false;
}
}
// Form mapping
protected $_map=array(
'uname'=>'username',
'pwd'=>'password',
);
//Autocomplete function
protected $_auto=array(
//array(fill field, fill content, fill condition, additional rules) Fill condition: 1, insert 2, update 3, all
array('reg_date', 'getDate',1,'callback'),
array('password','md5',3,'function'),
);
function getDate(){
return date( 'Y-m-d H:i:s');
}
