Use of foreach in the Controller and use of output it in the view

I use codeigniter. How can put foreach in the Controller and use only of output it in the view.(i not want put foreach in the view) ?

foreach ($output->result() as $row)
{
    echo '<option>'.$row->name.'</option>';
}

This is my view now:

<select>
<option disabled="disabled" value="">selected</option>
<?php 
foreach ($output->result() as $row) { 
   echo '<op开发者_运维百科tion>'.$row->name.'</option>'; 
} 
?>
</select>

I want this in the view:

<select>
<option disabled="disabled" value="">selected</option>
<?php 
    echo $output_foreach_from_Controller; 
?>

Although the logic wants the foreach to be inside the view (it's a presentational thing, after all, and Controllers shouldn't do any data manipulation of sorts. Since you're using a db method, you might want to put that in the model, although "logically" wrong too...)

Anyway, coming to your question...You can assign it to a variable, and pass that to the view:

In controller:

function whatever()
{
$string = '';

foreach ($output->result() as $row) { 
   $string .= '<option>'.$row->name.'</option>'; 
} 

$data['foreach_output'] = $string;

$this->load->view('viewfile',$data);
}

in view:

<select>
<?php echo $foreach_output;?>
</select>

Maybe you can use 'form_dropdown' form_helper. See: http://codeigniter.com/user_guide/helpers/form_helper.html I hope this help to you.

I think in the controller you can assign the value ... to a variable and then pass that variable to the view. See something like given below:

<?php 

$variable = "";

foreach ($output->result() as $row) {
   $variable = $variable . '<option>'.$row->name.'</option>';
}

$data["option_values"] = $variable;

$this->load->view('view-name', $data);

?>

And then echo the "$option_values" variable in the view where you wan

I think you should really put the foreach in the view. You can also use the template version of foreach to make it look nicer:

<select>
    <option disabled="disabled" value="">selected</option>
    <?php foreach ($output->result() as $row): ?>
    <option><?php echo $row->name.; ?></option>
    <?php endforeach; ?> 
</select>

The reason for this is that if you generate HTML in the controller it's not immediately obvious what is being output.
