dynamic inputs and validation

[eluser]robert.fulcher[/eluser]
I am trying to validate and repopulate fileds on a form that I also add dynamically. Not dynamically from JavaScript but from database variables.

I have a preferred number of fields that will be added to a form.

Form HTML

Code:

<?php echo form_input('value['.$howmany.']', set_value('value['.$howmany.']')); ?> <?php echo form_error('value['.$howmany.']'); ?>

Generated HTML

Code:

<input type="text" name="value[1]" value=""  />
<input type="text" name="value[2]" value=""  />
<input type="text" name="value[3]" value=""  />
<input type="text" name="value[4]" value=""  />

Controller

Code:

$this->form_validation->set_rules('value[]','Communication Value');

I read about some posts that addressed the index value in the array with patches and things. I am still new to CI so I am not sure if this is supposed to be working or not. The re-population does not work.

Any help would be great. Thanks

Still looking for input on this if anyone has it. Am I even close with how this should work?

Thanks

Hi Robert,

did you try to set up the input fields this way ?

Code:

<input type="text" name="value[]" value=""  />
<input type="text" name="value[]" value=""  />
<input type="text" name="value[]" value=""  />
<input type="text" name="value[]" value=""  />

I didn'd test but looking at the user guide it seems to be the direction to go.

Have a look here:

Normally it should work to validate an array but as the dynamic fields come out of a database why not do

Code:

<?php echo form_input('value_'.$howmany, set_value('value_'.$howmany)); ?> <?php echo form_error('value_'.$howmany); ?>

And in the controller

Code:

for($i=1;$1<=$data['howmany'];$i++)
{
   $this->form_validation->set_rules('value_'.$i,'Communication Value '.$i,'required');
}

Array validation is still a bit clunky even with the new validation class.
