Stripping blank lines

[FreddoB]

I have the following that works fine and returns the item and quantity but returns a blank line for every non-selected item.

 

<?php

$plantname1 = $_POST['plantname1'];
$quantity1 = $_POST['quantity1'];
foreach($_POST['plantname1'] as $key => $plantname1)

{
   $quantity1 = isset($_POST['quantity1'][$key])? $_POST['quantity1'][$key]:'Not selected';
   if($quantity1 != 0);
   else ($plantname1 = ''. $quantity1 = '') ;
   $message[ ] = $quantity1.'  '. $plantname1  ;}   

echo implode('<br>', $message);

?>

 

I've tried various ways of stripping the empty lines but nothing is working. Any suggestions?

If it doesn't do what you want then it doesn't work fine.

 

Your if block is useless. Semicolons end statements, even if that statement is empty.

 if($quantity1 != 0);
   else ($plantname1 = ''. $quantity1 = '') ;

If true then do nothing else do nothing.
