I am have this issue:
<fieldset>
<?php
echo form_open('rssFeedReader/addSource');
echo '<h2><small>(*) Select in which category you want to add a new Rss Source </small><h2>';
echo '<div class="form-group">';
echo '<select class="form-control input-lg" name="category" id="category">';
foreach( $categories as $row )
{
// here i have some values from my database
echo '<option value="'.$row->id.'">' . $row->category_name . '</option>';
}
echo '</select>';
echo '</div>';
// NOW, HERE I WANT TO PUT ANOTHER <SELECT>
echo '<div class="form-group">';
echo '<select class="form-control input-lg" name="anotherID" id="anotherID">';
foreach( $array as $r)
{
// here i have some values from my database
echo '<option value="'.$r->something.'">' . $r->something_else. '</option>';
}
echo '</select>';
echo '</div>';
echo '<div class="form-group">';
echo form_submit(array('class' => 'btn btn-primary btn-lg btn-block', 'id' => 'remove_source', 'name' => 'remove_source', 'value' => 'Remove Source'));
echo '</div>';
?>
<?php echo validation_errors('<p class="error">'); ?>
Now, what I want to do. The second select list is empty initially. I want to fill it with values depending of what is chose in first select list.
How can I do that? To fill the second select list only if something is selected in first select list.
