Prefill forms from DB array

[eluser]opel[/eluser]
Please could anyone tell me if it is possible or how to prefill a form view with data from my model and controller ?

What I have at the moment is :

Model :

Code:

function get($table, $id)
    {
        $query = $this->db->query("SELECT * FROM $table WHERE $id");
        $result =  $query->row();
    
        var_dump($result);
    
    }

Controller :

Code:

function edit($id){
        
        $data['pagetitle'] = 'Edit';
        
        //Select data based on ID
        $data['body'] = $this->Pages_model->Get('pages', $id);
        
        //write out data
        $this->template->write_view('content', 'pages/page_add', $data);
        
        //render
        $this->template->render();
        
    }

View :

Code:

<h1>&lt;?= $pagetitle; ?&gt;</h1>

&lt;?php

  $id = $this->uri->segment(3);

if($id == NULL){
  $id = 'X';
}




$form = array('name'=>'text','rows' => '10', 'cols' => '30');

$attributes = array('class' => 'email', 'id' => 'myform');

echo form_open('pages/form', $attributes); ?&gt;


&lt;?php echo $this->validation->error_string; ?&gt;

<table>
    <tr>
         <td><label><div align="right">Title : </div></label></td>
        <td>&lt;?= form_input('title'); ?&gt;</p></td>
    </tr>
    <tr>
             <td><label>Message : </label></td>
            <td colspan="2">&lt;?= form_textarea($form); ?&gt;</p></td>
    </tr>
    <tr>
             <td><label><div align="right">Order : </div></label></td>
            <td>&lt;?= form_input('order'); ?&gt;</p></td>
    </tr>
    <tr>
            <td>&nbsp;</td>
            <td>&lt;?= form_submit('submit', 'Add Page') ?&gt;</td>
    </tr>
    <tr>
            <td>&nbsp;</td>
            <td>&lt;?= form_hidden('id', $id) ?&gt;</td>
    </tr>
</table>
&lt;? echo form_close(); ?&gt;

Since the data is going into a variable

Code:

$data['body'] = $this->Pages_model->Get('pages', $id);

In the view it becomes an array.

Code:

<input type="text" value="<?=$body['column title']?>">

You need to replace column title with the columns in the array.

Thanks I was hoping the Forms helper may have something in it for setting the defaults. I used to use HTML Quickforms in PEAR and you could just do $form->set defaults and it would prefill input fields if the array and form names matched up.

CI has nothing like this built in but you can hack the same sort of effect.

in your controller after your validation rules have been set enter:

Code:

$this->data->whatever = $this->whatever_model->getWhatever($id);

foreach(array_keys($rules) as $field) {
    if(isset($_POST[$field])) {
        $this->data->whatever->{$field} = $this->validation->{$field};
    }
}

Then in your views, you can just have:

Code:

<?=form_input('order', $whatever->order);?>

It might look a little crazy, but it works very well. You are basically getting the data from the db, then unless the POST variable has a more up to date version, you are putting the DB values into the form.

Would be nice to have a way of doing this a little easier, but I think getting too involved in CRUD automation is a very bad idea. Every system I have ever used to do this has made my life harder, more stressful and less productive! >.<

pyro that code is super helpful! Thanks for the post, I'll be using this later today.

[eluser]opel[/eluser]
could this code be made into a helper so it is reusable across all classes?

[eluser]opel[/eluser]
Pyro do you have an example of your controller or views that you could post up please ?

I have been trying to follow this in the wiki but getting nowhere : http://codeigniter.com/wiki/Add_Edit_Views/
