Testing for last item in loop Can't Post
Hi there,

I need to test for the last item in a navbar so i can remove the separator " | ", could not find it in the forum.

Here is the code:

Code
<?php 
  // load records 
  list($pagesRecords, $pagesMetaData) = getRecords(array( 
    'tableName'   => 'pages', 
    'loadUploads' => '0', 
    'allowSearch' => '0', 
    'where'	  => 'footer_nav ="1"', 
    'useSeoUrls'  => true, 
  )); 
?>

Code
<?php foreach ($pagesRecords as $record): ?> 
<a href="<?php echo $record['_link'] ?>"><?php echo $record['name'] ?> </a> |  
<?php endforeach ?>

Many thanks

Hi Jan,

One approach would be to put all your menu links into a string and then use the rtrim() function to remove the last | from the string.

For example:

Code
<?php $menu = ""; ?> 
<?php foreach ($pagesRecords as $record): ?>  
  <?php $menu .= " <a href=\"". $record['_link'] ."\">". $record['name']." </a> |"; ?>   
<?php endforeach ?> 
 
<?php $menu = rtrim($menu, "|"); ?> 
<?php echo $menu; ?>


Hope this helps

What I often do for this is use the 'implode' function:

Code
<?php 
 
$menuItems = array(); 
foreach ($pagesRecords as $record){ 
    $menuItems[] = "<a href=" . $record['_link'] . "> " . $record['name']  . "</a>" 
} 
 
$menu = implode(' | ', $menuItems); 
 
echo $menu; 
?>
