Array of fields with only a number as there id

Hi all,

I have a problem for you to wrap your brains around.

How can you tell the differene between a row of fields which all have the same html name tag.

Image shown below


This was cceated using a for loop of 14 times and within it using the form_helper functions.

Code:

for ($i =0; $i< 15; $i++)
                {
            
                    
                    //time part of event field
                    echo form_input ($i),
                    //the event itself
                    form_input ($i),
                    //supplies used
                    form_input ($i),
                    //successful?
                    form_dropdown ($i, $success),
                    //comment if necessary
                    form_input ($i);
                    echo '<br/>';
                }

I thought about concatenating them:

e.g.

Code:

form_input ("time".$i);

To give a unique name for each field within a single row but I dont know if that would work using a forloop later on in my validation controller?

How will i be able to distinguish so I know that this is e.g.

"supply field no 15 out of 30 etc?"

Is there another variable I can put in form_input function?

Thanks

You could dynamically add validation for the dynamic fields.

Code:

$this->form_validation->set_rules('time'.$i, 'Username', 'required');

How would form_validation know that?

Because in the view it will be rendered as "time1, time2, time3" and will not be recognized as 'time'.$i etc.

So when it goes to post it will be time1,time2,time3 ?

I have a possible idea,

What if i was to have an actualy variable like $i which was an array populated by my fields (time,event, supplies, success, comment) and just record the total index value and then in my validation controller pass them all through in a for loop of $i?

In your controller would the stay loop as you'll do in the view.

Code:

//in your controller
for ($i =0; $i< 15; $i++)
{
  $this->form_validation->set_rules('time'.$i, 'Time', '');            
  :
}

if ($this->form_validation->run() == FALSE)
{

//in your view
for ($i =0; $i< 15; $i++)
{
  
  
  //time part of event field
  echo form_input ($i),
  //the event itself
  form_input ($i),
  //supplies used
  form_input ($i),
  //successful?
  form_dropdown ($i, $success),
  //comment if necessary
  form_input ($i);
  echo '<br/>';
}
