What is the return value of the add method in thinkphp

ThinkPHP's built-in add method is used to add data to the data table, which is equivalent to the INSERT INTO behavior in SQL.

Usage examples are as follows:

$User = M("User"); // 实例化User对象
$data['name'] = 'ThinkPHP';
$data['email'] = 'ThinkPHP@gmail.com';
$User->add($data);

Or use the data method to operate continuously

$User->data($data)->add();

If the data object has been created before add (for example, the create or data method is used), add The method no longer needs to pass in data.

When the add() method succeeds, it returns the id of the inserted data. When it fails, it returns false.

That is to say, when we judge whether add() is successful, we only need to judge whether the result is equal to false

if($result===false){
echo "添加失败！";
}else{
echo "添加成功";
}
