displaying form array help

[corbeeresearch]

Consider this scenario:

 

I'm using an ajax to make the form use only one page

 

I got a multistep form with step3 being the result of step2, within step3 there is an "add more steps" button which duplicates step2 and step3, this can be done countless times.

 

to complement this I added array to my input boxes something like this:

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

 

unfortunately, I'm not sure how to approach this in the php.

In the step2 going to step3, I would call the brand id and use it in the database to get the results for step3, but now it's array

I added the following lines

$brand = $this->input->post('brand[]');
$this->load->model('MBest');
$q = $this->MBest->getbestmatching($brand[0]);

 

But the $brand[0] doesn't works and triggers an error.

 

And come to think of it, if I call a

$brand[0]

index, then everytime a person add a new step, it will always use the id of the first result.

 

Are there any ideas on how to fix this problem? Thanks

I tried doing the following code in the controller that is responsible for passing step2 data to step3

 

$brandID = $this->input->post('brand[]');
$this->load->model('MBest');
for($x=0;$x<count($brandID);$x++)
{
$brand[] = $brandID[$x];
}
print_r($brand);
$q = $this->MBest->getbestmatching(end($brand));

 

unfortunately

I get

Array ( [0] => ) 

in the result.

 

But when I look at the ajax request in firebug

I found that brand did post a value.

 

Where did I go wrong?

.change

$brandID = $this->input->post('brand[]');

to

$brandID = $this->input->post('brand');

Thanks it works!

 

Unfortunately, I found another problem I realize that my form has a back and next button.

 

That means that when I clone the step2 and step3, going back to an earlier step2 would get the latest step3 brand id instead of the current one.

 

Then using

end($brand)

would not be applicable

 

Is there a way to make the code understand which index it should be?

 

Thanks again

can you post your form code

It's hideously long, is it okay?
