Form Validation (Twice) - El Forum - 02-06-2009

Is it possible to run a validation process twice, one inside the other?

Example:
Code:
if($this->form_validation->run('val1') == FALSE):
  // -- False
else:
    if($this->form_validation->run('val2') == FALSE):
        // -- False
    else:
    endif;
endif;

For some reason I can't seem to get it to work... any help would be appreciated, thanks!

do you have a reason on why you would want to run it twice?

Ya, I'm trying to get past some credit card authorization problems that are apart of the form.

I still don't understand why you would need to validate twice... maybe if you provide a more detailed example we can help you out.

I am running the validation twice in one of my controllers because I want to validate one rule before all others. This way I don't get all of the error message of the second validation if the first one didn't even pass.

I am using this approach:

Code:
// set first validation rule
$this->form_validation->set_rules(...);

// only if first rule passed, check for other rules            
if ($this->form_validation->run() == TRUE)
{
    $this->form_validation->set_rules(...);
    $this->form_validation->set_rules(...);
}

// if first rule didn't pass the form only displays an error for the first rule
if ($this->form_validation->run() == FALSE)
{
    // then re-populate form
}

Is that something you anticipated?

Hi Michael,
I am trying a different route for dealing with credit card validation/processing. Before, I would authorize the card at the same time as validating the form and stored the authorization status in a session variable. So if the form didn't validate, it wouldn't try and authorize their card on each failed form validation attempt. Thus, I was using an AUTH_ONLY, then PREVIOUS_SALE - 2 function calls for the credit card.

I was trying to bypass this method and use 2 validations and not set session variables so I can then use an AUTH_CONVERT for the CC. I validate the form first as there are two payment methods, 1 for credit card and 1 for paypal, which has two different validation arrays.

I hope that helps, thanks guys!

EDIT: @ macigniter

I guess my way about it is a more nested approach.... Not sure if it matters? Might need to pull it out of each other and basically have it similar to your case.

Code:
if($this->form_validation->run('val1') == FALSE):
    // -- Stop processing
else:
    $bool = TRUE;
endif;

if($bool):
    // -- run val2
endif;

As an update, I tried doing it without the nesting and it doesn't work either...

Any updates to this? Can't get it working...

Does anyone have suggestions on how to work cc processing with CI validation of forms? I really don't want to use a session variable to store an auth status...

Hi,

I had the same problem today, and I made a very quick fix (Surely there is another more fashionable method).

I extended CI_Form_validation class, and I set my version of run method:

---------------------------------------------------------------------------------------

Code:
function run($group = '', $use_only_group = false)
    {
        // Do we even have any data to process?  Mm?
        if (count($_POST) == 0)
        {
            return FALSE;
        }
        
        if ($use_only_group) {
            // If user tells to use explicitly use
            // configuration from argument, then
            // don't reuse last configuration
            $this->_field_data = array();
        }      
        // Does the _field_data array containing the validation rules exist?
        // If not, we look to see if they were assigned via a config file
        if (count($this->_field_data) == 0)
        {
            // No validation rules?  We're done...
            if (count($this->_config_rules) == 0)
            {
                return FALSE;
            }
            
            // Is there a validation rule for the particular URI being accessed?
            $uri = ($group == '') ? trim($this->CI->uri->ruri_string(), '/') : $group;
            
            if ($uri != '' AND isset($this->_config_rules[$uri]))
            {
                $this->set_rules($this->_config_rules[$uri]);
            }
            else
            {
                $this->set_rules($this->_config_rules);
            }
    
            // We're we able to set the rules correctly?
            if (count($this->_field_data) == 0)
            {
                log_message('debug', "Unable to find validation rules");
                return FALSE;
            }
        }
    
        // Load the language file containing error messages
        $this->CI->lang->load('form_validation');
                            
        // Cycle through the rules for each field, match the
        // corresponding $_POST item and test for errors
        foreach ($this->_field_data as $field => $row)
        {        
            // Fetch the data from the corresponding $_POST array and cache it in the _field_data array.
            // Depending on whether the field name is an array or a string will determine where we get it from.
            
            if ($row['is_array'] == TRUE)
            {
                $this->_field_data[$field]['postdata'] = $this->_reduce_array($_POST, $row['keys']);
            }
            else
            {
                if (isset($_POST[$field]) AND $_POST[$field] != "")
                {
                    $this->_field_data[$field]['postdata'] = $_POST[$field];
                }
            }
        
            $this->_execute($row, explode('|', $row['rules']), $this->_field_data[$field]['postdata']);        
        }

        // Did we end up with any errors?
        $total_errors = count($this->_error_array);

        if ($total_errors > 0)
        {
            $this->_safe_form_data = TRUE;
        }

        // Now we need to re-set the POST data with the new, processed data
        $this->_reset_post_array();
        
        // No errors, validation passes!
        if ($total_errors == 0)
        {
            return TRUE;
        }

        // Validation fails
        return FALSE;
    }
