return false;
}


}


Table Name : About

ID: 1;
Field :  'hello fr. data inserted in row';

route



$route['admin/about'] = 'admin/admin/about';

$route i use for shortcut....


Note ::  <?php if($about->field!=''){ echo $about->field; } ?> in text area .html field.

$about is database name

(Field) is a table row name

Rule : if

<input type="hidden" name="id" value="<?php if($about->id!=''){ echo $about->id; } ?>" id="t3">
