Form Validation Repopulation with Form Helper

[eluser]Dan Bowling[/eluser]
I'm having a little trouble finding the proper syntax for repopulating a form after it fails the form_validation class. The example on the User Guide doesn't use the form_helper.

How should I repopulate form data with check boxes, drop downs, and radio buttons that use the form_helper?

Any generic example would help.

I had a hard time with that issue too. I'm not sure if this is the 'proper' way to do it, but i find this works pretty well.

HTML code:

Code:

<input name='text_box' value='<?php echo set_value('text_box'); ?>' />

Like i said, not sure if that's the proper way to do it.

Remember, you'll have to load the 'form' helper to use it.

oops, I should have read your post more carefully:
sorry...


Here's what I do for select fields:

Code:

<select name='select_id'>
  <option value='' ></option>
  &lt;?php foreach($select_items as $item):?&gt;
    &lt;?php if(set_value('select_id') == $item['select_id']):?&gt;
      <option value='&lt;?php echo $item['select_id']; ?&gt;' selected > &lt;?php echo $item['text']; ?&gt;</option>
    &lt;?php else: ?&gt;
      <option value='&lt;?php echo $item['select_id']; ?&gt;' >&lt;?php echo $item['text']; ?&gt;</option>
   &lt;?php endif;?&gt;
  &lt;?php endforeach;?&gt;
</select>

Like many things involving code, there is probably a better way. This is just one example of how you could do it.

Thanks for the suggestion.

I've been able to do some similar stuff with my own methods for this, but what I am really looking for is some method that works with the Form Helper.

I was able to get the drop down to work alright

Code:

<?php
$options = array(
                  'small'  => 'Small Shirt',
                  'med'    => 'Medium Shirt',
                  'large'   => 'Large Shirt',
                  'xlarge' => 'Extra Large Shirt',
                );

echo form_dropdown('shirts', $options, set_value('shirts'));

?>

But I'm stuck with this for checkboxes and radio buttons:

Code:

<h5>Check Boxes</h5>
Red: &lt;input type="checkbox" name="checkbox[]" value="red" &lt;?=set_checkbox('checkbox[]', 'red'); ?&gt;/&gt;
Blue: &lt;input type="checkbox" name="checkbox[]" value="blue" &lt;?=set_checkbox('checkbox[]', 'blue'); ?&gt;/&gt;
Green: &lt;input type="checkbox" name="checkbox[]" value="green" &lt;?=set_checkbox('checkbox[]', 'green'); ?&gt;/&gt;

<h5>Radio</h5>
Radio 1: &lt;input type="radio" name="myradio" value="1" &lt;?php echo set_radio('myradio', '1', TRUE); ?&gt; /&gt;
Radio 2: &lt;input type="radio" name="myradio" value="2" &lt;?php echo set_radio('myradio', '2'); ?&gt; /&gt;

The difference in elegance is astonishing. I guess it's more a matter of keeping my code clean, and consistent (in regards to using the form helper or not.)

I was thinking about using the form helper with the form validator as I was reading through the user guide just now and wondering about the same question.

Has anyone actually integrated the set_XXXX() functions into the form helper form_XXXX() functions?

If so, please share! :-)

If not, I'll eventually do that myself. Then I'd never have to worry about form population again.
