Question

I am really confused about how I should approach/implement a filter feature.

So I am a simple checkbox with 4 values: val1, val2, val3, val4 which has to act like a category filter. If user selects val1 and val3 will show results only from that category.

Ok so the problem is how should I implement this feature in the backend. I think the best idea would be to use a switch function but the problem is that $filterData brings values in this format: val1,val3,val4 so a switch and a case would work.

I was thinking of trying to implode it using ‘,’ as a glue but from what I have tried I didn’t succeed until now.

It should work something like this

switch ($filterData)
{
      case 'Values of filter data' (ex: val3 and val4 ):
          $result[$value.'Results'] = $this->_$value($data);
      break;
}
return $result;

I have tried to do a

$filterData = implode(',',$filterData);
foreach ($filterData as $key => $value)
{
     switch ($value){
         case $value:
              $result[$value.'Results'] = $this->_$value($data);
         break;}
}

but the problem is that this will return this:

Array
(
    [value1Results] => value1
)

Array
(
    [value1Results] => value1
    [value2Results] => value2
)

Array
(
    [value1Results] => value1
    [value2Results] => value2
    [value3Results] => value3
)

Any ideas how to implement/fix this?

Ok, here is the solution that works for me

$filterData = explode(',', $parameters['filter']);
     foreach ($filterData as $key => $value)
     {
             switch($value)
             {
                 case $value:
                     $value = '_'.$value;
                     $searchResults[$value] = $this->$value($parameters);
                 break;
             }
     }
