1. Use object method to insert data D usage. $Form = D (' form '), $data [' title '] = ' thinkphp '; $data [' content '] = ' form contents '; $Form->add ($data); In fact, thinkphp also supports the object to insert data directly into the database, as follows: $Form = D (' form '), $Form->title = ' thinkphp '; $Form->content = ' form content '; $Form Add (); 2, do not specify conditions for data updates. $Form = M ("Form"); The data object property to be modified is assigned the value $data[' id ' = 5; $data [' title '] = ' thinkphp '; $data [' content '] = ' ThinkPHP3.1 version released '; $Form->save ($data) ; Saving modified data According to conditions the Save method automatically recognizes the primary key field in the data object and acts as an update condition. Of course, you can also explicitly pass in the update condition, which is our most commonly used method: $Form = M ("Form");//The Data object property to be modified $data[' title ' = ' thinkphp '; $data [' content '] = ' ThinkPHP3.1 release '; $Form->where (' id=5 ')->save ($data); Saving the modified data according to the condition actually has the way of the object, as mentioned above, insert the data, the same way as the object: $Form = M ("Form");//The Data object property assignment to be modified $form->title = ' thinkphp '; $Form- >content = ' ThinkPHP3.1 version released '; $Form->where (' id=5 ')->save (); The modified data is saved according to the condition and the primary key field can be contained in the data to be saved, so that you can write where $form = M ("Form"), and/or the data object property to be modified $form->id = 5; $Form->title = ' thinkphp '; $Form->content = ' ThinkPHP3.1 release '; $Form->save (); Saves modified data 3, modification of a single field value, based on the primary key in the data object. There are times when IYou only need to modify the value of a field, you can use the SetField method without having to call the Save method every time. $Form = M ("Form"); Change the title Value $form->where (' id=5 ')->setfield (' title ', ' thinkphp '); 6. Strong Increment/Decrement field value operation. Thinkphp, you can perform a direct or decrement operation on a field's data. For statistical fields, the system also provides a more convenient method for Setinc and Setdec. $User = M ("User"); Instantiate the User object $user->where (' id=5 ')->setinc (' Score ', 3); The user's points plus 3$user->where (' id=5 ')->setinc (' score '); User's points plus 1$user->where (' id=5 ')->setdec (' Score ', 5); User's points minus 5$user->where (' id=5 ')->setdec (' score '); The user's points are reduced by 17 and the where is not used to perform the deletion. $User->delete (' 1,2,5 '); Delete the user data for primary keys 1, 2, and 5. This usage can be used in an example of an auto-increment of user points, similar to the sign-in time. 8. Print SQL statement echo $User->getlastsql (), or Echo $User->_sql (); loop output volist also alias iterate template assignment: $User = D (' User ') $list = $ User->findall () $this->assign (' list ', $list) template definition: <iterate name= "list" id= "Vo" >{$vo.
