Help With foreach loop

[limitphp]

I have multiple check boxes.

<input name='c[]' type='checkbox' value='$id'>

I grab the value of the selected check boxes with

if ($_POST['mode']=='1')
{
foreach ($_POST['c'] as $value) {
	//do stuff here
};
}

its working great.

I just need it to grab another value for me.....another id....a commentID

 

I'm not sure how to do that.

My first method:

Would I make a hidden input in the form like:

<input name='commentID[]' type='hidden' value='$songCommentID'>

 

My second method:

Could I just add a comma and the commentID value to the checkbox?

<input name='c[]' type='checkbox' value='$id,$songCommentID'>

 

Or is there a better easier method?

With the first method, I don't know how I would grab the value of commentID.  I would only want the value if the c[] checkbox is checked.  Would I add another foreach loop inside the foreach ($_POST['c'] as $value loop?

 

With the second method, how would I modify the foreach loop to grab both values?

 

thanks....

The first method is better imo.

I'd do something like:

 

if( isset($_POST['commentID']) && isset($_POST['c']) ) {
  if( ($cap = count( $_POST['commentID'] )) == count( $_POST['c'] ) )
  {
       for( $i = 0; $i < $cap; $i++ )
       {
           echo $_POST['commentID'][$i]." <-related->".$_POST['c'][$i];
       }
   }
   else
   {
      echo "Sorry invalid data";
   }
}

       {

       }
   }
   else
   {
      echo "Sorry invalid data";
   }
}

 

What is:

if( ($cap = count( $_POST['commentID'] )) == count( $_POST['c'] ) )

for?

To check if the number of commentIDs equal the number of 'c's otherwise there will be an issue with $_POST['c'][$i]. I guess they don't have to be equal. As long as commentIDs is smaller than or equal to cs, it should work.
