THINKPHP method for obtaining the value of the primary key id when adding data, thinkphp primary key

After using ThinkPHP to add data, you can easily obtain the Automatically increasing primary key value.

$ Model = D ('blog '); $ data ['name'] = 'test'; $ data ['title'] = 'test title '; $ data ['content'] = 'test content'; $ result = $ Model-> add ($ data); if ($ result) {$ id = $ result; // obtain the primary key for writing data to the database} else {exit ($ Model-> getError ());}

If the primary key of your data table is automatically increasing, the return value after the add method is successful is the primary key value of the data. No additional information is required.

The above THINKPHP method used to obtain the value of the primary key id when adding data is all the content shared by the editor. I hope it can be used as a reference for you. I also hope that you can provide more support for helping customers.
