The create () method of thinkPHP, but are you sure you want not to add it?

{Code...} I see the example. how can I add an add ()? is there a problem with my settings, or is it necessary to add an add when I create a file?

// Create a new Member data object from the User data object $ User = stdClass (); $ User-> name = 'thinkphp '; $ User-> email = 'thinkphp @ gmail.com '; $ Member = M ("Member"); $ Member-> create ($ User );

Let me look at the example. you have to add ();
Is there a problem with my settings, or do I have to add after creating?

Come back for running, answer.
1. the M method source code is as follows, which is used to instantiate a model without a Model file.

/*** Instantiate a Model without a Model file * @ param string $ name Model name. you can specify a basic Model, such as a Model: user * @ param string $ tablePrefix table prefix * @ param mixed $ connection database connection information * @ return Think \ Model */function M ($ name = '', $ tablePrefix = '', $ connection ='') {static $ _ model = array (); if (strpos ($ name, ':') {list ($ class, $ name) = explode (':', $ name);} else {$ class = 'think \ model';} $ guid = (is_array ($ connection )? Implode ('', $ connection): $ connection). $ tablePrefix. $ name. '_'. $ class; if (! Isset ($ _ model [$ guid]) $ _ model [$ guid] = new $ class ($ name, $ tablePrefix, $ connection ); return $ _ model [$ guid];}

2. the source code of create is as follows: it has been commented out. only objects are created, and some filtering and verification operations are performed without being saved to the database.

/*** Create a data object but not save it to the database * @ access public * @ param mixed $ data create data * @ param string $ type status * @ return mixed */public function create ($ data = '', $ type = '') {// if no value is passed, the default value is POST data if (empty ($ data) {$ data = I ('post. ');} elseif (is_object ($ data) {$ data = get_object_vars ($ data) ;}// verify the data if (empty ($ data) |! Is_array ($ data) {$ this-> error = L ('_ DATA_TYPE_INVALID _'); return false;} // status $ type = $ type? :(! Empty ($ data [$ this-> getPk ()])? Self: MODEL_UPDATE: self: MODEL_INSERT); // Check the field ing $ data = $ this-> parseFieldsMap ($ data, 0 ); // check the validity of the submitted field if (isset ($ this-> options ['field']) {// $ this-> field ('field1, field2... ')-> create () $ fields = $ this-> options ['field']; unset ($ this-> options ['field']);} elseif ($ type = self: MODEL_INSERT & isset ($ this-> insertFields) {$ fields = $ this-> insertFields;} elseif ($ type = self:: MODEL_UPDATE & isset ($ t His-> updateFields) {$ fields = $ this-> updateFields;} if (isset ($ fields) {if (is_string ($ fields )) {$ fields = explode (',', $ fields);} // judge the TOKEN verification field if (C ('token _ on ')) $ fields [] = C ('token _ name', null, '_ hash _'); foreach ($ data as $ key => $ val) {if (! In_array ($ key, $ fields) {unset ($ data [$ key]) ;}}// automatically verifies if (! $ This-> autoValidation ($ data, $ type) return false; // form token verification if (! $ This-> autoCheckToken ($ data) {$ this-> error = L ('_ TOKEN_ERROR _'); return false ;} // verify that the generated data object if ($ this-> autoCheckFields) {// when field detection is enabled, the invalid field data is filtered $ fields = $ this-> getDbFields (); foreach ($ data as $ key => $ val) {if (! In_array ($ key, $ fields) {unset ($ data [$ key]);} elseif (MAGIC_QUOTES_GPC & is_string ($ val )) {$ data [$ key] = stripslashes ($ val) ;}}// after creation, the data is automatically processed. $ this-> autoOperation ($ data, $ type ); // assign a value to the current data object $ this-> data = $ data; // return the created data for other calls return $ data ;}

3. source code of the add method: There are several insert methods in it, that is, inserting data into the database.

/*** Add data ** @ access public * @ param mixed $ data * @ param array $ options expression * @ param boolean $ replace whether to replace * @ return mixed */public function add ($ data = '', $ options = array (), $ replace = false) {if (empty ($ data) {// no data is transferred, get the value of the current data object if (! Empty ($ this-> data) {$ data = $ this-> data; // reset data $ this-> data = array ();} else {$ this-> error = L ('_ DATA_TYPE_INVALID _'); return false ;}// data processing $ data = $ this-> _ facade ($ data ); // analysis expression $ options = $ this-> _ parseOptions ($ options); if (false ===$ this-> _ before_insert ($ data, $ options )) {return false;} // write data to the database $ result = $ this-> db-> insert ($ data, $ options, $ replace); if (false! ==$ Result & is_numeric ($ result) {$ pk = $ this-> getPk (); // add a composite primary key to support if (is_array ($ pk )) return $ result; $ insertId = $ this-> getLastInsID (); if ($ insertId) {// Insert ID returned by auto-increment primary key $ data [$ pk] = $ insertId; if (false ===$ this-> _ after_insert ($ data, $ options) {return false;} return $ insertId ;} if (false ===$ this-> _ after_insert ($ data, $ options) {return false ;}} return $ result ;}

Conclusion: The M method instantiates a model class without the model file. The create method only prepares data and is not inserted. The create method inserts data into the database. PS: You can directly look at the source code for this problem.
