<\/div>\nCreating Database Table (users):<\/h2>\n
Before start to writing the code, create a table into your application’s database. For this example you can create a Create a controller called We’ve used some required Preferences in our file upload configuration. You can get all the available Preferences from here – https:\/\/codeigniter.com\/user_guide\/libraries\/file_uploading.html#preferences<\/a><\/p>\n Create a model called users<\/code> table into the database with some basic fields. The users table SQL would like the below.<\/p>\nCREATE<\/span> TABLE<\/span> `users<\/span>` (\r\n `id`<\/span> int<\/span>(11<\/span>) NOT NULL<\/span> AUTO_INCREMENT,\r\n `name`<\/span> varchar<\/span>(100<\/span>) COLLATE utf8_unicode_ci NOT NULL<\/span>,\r\n `email`<\/span> varchar<\/span>(255<\/span>) COLLATE utf8_unicode_ci NOT NULL<\/span>,\r\n `picture`<\/span> varchar<\/span>(255<\/span>) COLLATE utf8_unicode_ci NOT NULL<\/span>,\r\n `created`<\/span> datetime NOT NULL<\/span>,\r\n `modified`<\/span> datetime NOT NULL<\/span>,\r\n `status`<\/span> tinyint<\/span>(1<\/span>) NOT NULL<\/span> DEFAULT '1'<\/span> COMMENT '1=Active, 0=Inactive'<\/span>,\r\n PRIMARY KEY<\/span> (`id`<\/span>)\r\n) ENGINE=<\/span>InnoDB DEFAULT CHARSET=<\/span>utf8 COLLATE=<\/span>utf8_unicode_ci;<\/pre>\nController (Users.php):<\/h2>\n
