validating and displaying errors from multi-dimensional array

[thara]

To get famous sports from counties, I created this form.

 

$sports = array (
           'Australia' =>  array (
                           1 => 'Cricket',
                           2 => 'Foot Ball',
                           3 => 'Net Ball',
                           4 => 'Kabadi',
                           5 => 'Ragby',
                           6 => 'Basket Ball',
                           7 => 'Volley Ball',
                       ),          
         'New Zealand' =>  array (
                           1 => 'Cricket',
                           2 => 'Foot Ball',
                           3 => 'Net Ball',
                           4 => 'Ragby',
                           5 => 'Basket Ball',                         
                       ),        
             'England' =>  array (
                           1 => 'Cricket',
                           2 => 'Foot Ball',
                           3 => 'Net Ball',
                           4 => 'Ragby',
                           5 => 'Karom',                           
                           6 => 'Basket Ball',                         
                           7 => 'Table Tennis',                            
                           8 => 'Tennis',                          
                       ), 
               );

echo '<br><form action="" method="post">';
   foreach ( $sports AS $country => $sport ) { 
       echo "<h3>{$country}</h3\n";    
       foreach ($sport AS $k => $v) { 
           echo "<br /><input type='checkbox'  name='country-sport[{$country}][]' value='{$k}' />{$v}\n";
       } 
   }
echo "\n<br><input type='submit' value='go' />\n</form>";

 

My problem is When I am going to validate this. Here I need to check some conditions with this form validation.

• country-subject array is completely empty or not
  
• at least 1 or upto 3 sports for each countries have selected or not
  

these conditions not met need to display error message.

I tried something like this.. with this code I can get 1st error message which is if whole array is empty..

this is my validation code so far..

if ( isset($_POST['country-sport']) && is_array( $_POST['country-sport'])) {

   foreach ( $_POST['country-sport'] AS $country => $sport) {      

       if ( count( $sport ) >= 1 && count( $sport ) <= 3 ) { 


       } else {
           echo "select at leat 1 or upto 3 sports for each country";          
       }   
   }
} else {    
   echo 'You have not selected sports for any country!';
}

 

 

I am expecting someone can help me out...

Thank you.

nest another loop and use array_serach() to check the values, count the results found and error on condition of count
