Format a text field as a hyperlink

The following PHP formatter appends the content of a text field to a fixed URL to make a hyperlink.

$search_term = $variables['#items'][0]['safe_value'];
$url = 'http://www.streetmap.co.uk/loc/'.$search_term;
$options = array('attributes' => array('target'=>'_blank'));
Return l($search_term, $url, $options);

Format a decimal field showing or not the decimals

The decimal field ("number_decimal") always shows decimals wether or not your number has. For exemple if your number is "20", Drupal shows "20.00". With this custom formatter, Drupal will show the exact number in case the number doesn't have decimals, but will show the decimals if the number actually has.

$output = '';
foreach ($variables['#items'] as $item) {
  if(strpos($item['value'],".") !== false) {
    $output .= trim(trim($item['value'], '0'), '.');
  }
  else {
    $output .= $item['value'];
  }
}
return $output;

Failed attempt

ppatterson-edc commented 30 January 2012 at 02:32

I'm trying to remove the leading 0 from some averages, i.e.,

0.345
0.657

I would rather them print out to the screen as

.345
.657

I tried modifying your snippet, but it didn't work - can you help?

$output = '';
foreach ($variables['#items'] as $item) {
if(strpos($item['value'],".") !== false) {
$output .= ltrim($item['value'], "0");
}
else {
$output .= $item['value'];
}
}
return $output;
