This article will introduce you to the addition, deletion, modification and search operations under the ThinkPHP3 framework. I hope it will be helpful to developers who are learning the ThinkPHP3 framework.
- Add operation
In ThinkPHP3, you can use the M method to add a piece of data, for example:
$Model = M('User');
$data['name'] = 'wuzhi';
$data['password'] = md5('123456');
$result = $Model->add($data);
The above code means to instantiate the User model , and set the name and password attributes for it, and then insert the data into the database through the add method. $result is the primary key value returned after insertion.
- Query operation
To query a single data, use the find method, to query multiple data, use the select method, for example:
$Model = M('User');
$condition['id'] = 1;
$result = $Model->where($condition)->find();
The above code means query id User data of 1 and return the result.
$Model = M('User');
$condition['id'] = array('between',array(1,10));
$result = $Model->where($condition)->select();
The above code queries user data with IDs between 1-10 and returns the results.
- Modification operation
Use the save method to modify existing data, for example:
$Model = M('User');
$condition['id'] = 1;
$data['name'] = 'lisi';
$data['password'] = md5('654321');
$result = $Model->where($condition)->save($data);
The above code will change the name and The password is changed to lisi and 654321.
- Delete operation
Use the delete method to delete data, for example:
$Model = M('User');
$condition['id'] = 1;
$result = $Model->where($condition)->delete();
The above code deletes the user data with id 1.
The above is a basic introduction to the addition, deletion, modification and search operations under the ThinkPHP3 framework. In actual development, we need to flexibly use the above methods to achieve various functions. I hope this article can help everyone.
