Multiple Choice Results

Hi i have the following problem:

$result1 = 'Produkt 1'; (contains in database: option1 = A, option2 = '')

$result2 = 'Produkt 2'; (contains in database: option1 = ABS, option2 = '1F')

$result3 = 'Produkt 3'; (contains in database: option1 = FP, option2 = 'F')

Now I have a formsearch with checkboxes for the options, and I want only the results that are checked:

<input name="asia" type="checkbox" id="asia" value="A" />
<input name="bio" type="checkbox" id="bio" value="B" />
<input name="break" type="checkbox" id="break" value="F" />
<input name="piz" type="checkbox" id="piz" value="P" />
<input name="south" type="checkbox" id="south" value="S" />

<input name="glut" type="checkbox" id="glut" value="1" />
<input name="lak" type="checkbox" id="lak" value="F" />

Pseudocode:

if ($_POST of all checkboxes == ''){ 
   echo all results
}

if ($_POST['asia']!=''){
   echo only results with A in option1
}

if ($_POST['asia']!='' && $POST['bio']!=''){
      echo only results with A and B in option1
}

if ($_POST['break']!='' && $POST['piz']!='' && $POST['lak']!=''){
      echo only results with F and P in option1 and F in option2
}

I need always the products that compare with all selected checkboxes.

I know that i can make for every possibility a if or elseif, but is there a faster way e.g. with arrays

Thanks a lot for every suggestion

The usual approach to this is to give all the checkboxes the same name (which should end in [], e.g. name="name[]") and then treat $_POST['name'] as an array containing the values of all the checkboxes that are checked.

You can loop over it to deal with all the entries you have or use in_array to see if a specific value is there.

If you need to deal with sets of data, then you can use:

<input type="checkbox" name="name[asia][]" value="foo">
<input type="checkbox" name="name[asia][]" value="bar">

And then $_POST['name'] will be an associative array containing arrays.
