Hi All,
Had a problem with the form validation when trying to validate a form field that was part of an array.
When CI sensed it was an array it would put in through the _reduce_array function. If the field was blank it would return a empty string. This was a problem when it came to preg_matching as preg_match will return false on an empty string and the section of code that catches empty fields only catches NULL values, so it was returning a validation error on an empty field!!
Below is my mod (although crud), that gets round this problem. May be its something for v2 of CI...
Code:
/**
* Traverse a multidimensional $_POST array index until the data is found
*
* @access private
* @param array
* @param array
* @param integer
* @return mixed
*/
function _reduce_array($array, $keys, $i = 0)
{
if (is_array($array))
{
if (isset($keys[$i]))
{
if (isset($array[$keys[$i]]))
{
$array = $this->_reduce_array($array[$keys[$i]], $keys, ($i+1));
}
else
{
return NULL;
}
}
else
{
return $array;
}
}
//modified to return NULL instead of an empty string
if ($array=='')
{
unset($array);
$array = NULL;
}
return $array;
}
