I want to see if a text input is empty when a condition exists.
So I extend validation and write this function.
Code:
function _check_text($str,$type)
{
if (empty($str) && $type['item']==$type['value'] )
{
$this->set_message('_check_text',"You must fill .");
return FALSE;
}
return TRUE;
}Dimis

The required rule is to check if the field as a value. If the required rule isn't added and there is no value all the rules are omitted.

I don't think your check will ever be true or will always be true. The way your $type[‘item’]==$type[‘value’] works if you add an array to as the parameter to the rule with the keys item and value. The type of a POST value is most of the time a string but because php has weak typing you can check if it's numeric too. The numeric rule is in the Validation library and it also as a few rules to check the formating of the string.
You could add a check to see if the value for the post key is an array but that is it so your function would look like this
Code:
function($val,$type)
{
$types = array('string','numeric','float','array');
if( ! in_array($type,$types))
{
return FALSE;
}
$function = 'is_'.$type;
if( ! $function($val))
{
return FALSE;
}
return TRUE;

My code is
Code:
$test=array('item'=>$mylink,'value'=>'1');
$rules['path'] = "_check_text[$test]";validation problem - El Forum - 10-06-2008

You have to add the required rule. If there is no value there is no point of getting the type.

Anyway, I put the conditions at my controller
(if $check==something)
