Question

I use one view for adding/editing DB data:

<input name="blah" id="blah" value="<? set_selected('blah')?> />

In my controller for edit I do this:

$_POST['blah'] = 'DB value';
$this->load->view('...');

But the input field is blank. I want the inputs to be prepopulated for my edit case.

CI Views can take a data array as the second parameter as others have mentioned.

I don’t like the idea of setting the $_POST array and then passing that as your data array. $_POST should just be used for values passed from the UI form. Since you would have to manually set your $_POST array anyways, you might as well use a separate array object. I would create an array with all your set values. i.e. array(‘blah’ => $dbvalue); and pass that instead of a pre-populated $_POST array.

Secondly, your example code uses ‘set_selected()’. The function is ‘set_select()’ and is meant for a option tag. So there are two issues with that line of code. It needs to either be

 <input .... value="set_value('blah')" />

or

 <option ....value="v1" "set_select('blah', 'v1')">
