====== Drupal 修改图片链接 ======


===== imagefield链接到指定网页 =====

修改了 imagefield 中到原始图片的链接，实现到指定链接的功能。


修改文件 imagefield/imagefield_formatter.inc 


<code php>
function theme_imagefield_formatter_image_imagelink($element) {
  // Inside a view $element may contain null data. In that case, just return.
  if (empty($element['#item']['fid'])) {
    return '';
  }

  $item = $element['#item'];
  $original_image_url = file_create_url($item['filepath']);
  $class = 'imagefield imagefield-imagelink imagefield-'. $element['#field_name'];
  # return l($imagetag, $original_image_url, array('attributes' => array('class' => $class), 'html' => TRUE));
  $imagetag = theme('imagefield_formatter_image_plain', $element);
  # drupal_set_message( "<pre>" . print_r($imagetag, true) . "</pre>");
  $node = $element['#node'];
  return l($imagetag, $node->field_url[0]["value"], array('attributes' => a    rray('class' => $class), 'html' => TRUE));
}
</code>

主要加了下面两行：
<code php>
  $node = $element['#node'];
  return l($imagetag, $node->field_url[0]["value"], array('attributes' => a    rray('class' => $class), 'html' => TRUE));
</code>

===== imagecache图片链接 =====

修改文件 imagecache/imagecache.module 

<code php>
function theme_imagecache_formatter_imagelink($element) {
  // Inside a view $element may contain NULL data. In that case, just return.
  if (empty($element['#item']['fid'])) {
    return '';
  }

  // Extract the preset name from the formatter name.
  $presetname = substr($element['#formatter'], 0, strrpos($element['#formatter'], '_'));
  $style = 'imagelink';

  $item = $element['#item'];
  $item['data']['alt'] = isset($item['data']['alt']) ? $item['data']['alt'] : '';
  $item['data']['title'] = isset($item['data']['title']) ? $item['data']['title'] : NULL;

  $imagetag = theme('imagecache', $presetname, $item['filepath'], $item['data']['alt'], $item['data']['title']);
  $path = file_create_url($item['filepath']);
  $class = "imagecache imagecache-$presetname imagecache-$style imagecache-{$element['#formatter']}";
  $node = $element['#node'];
  #drupal_set_message ( "<pre>" . $class ."</pre>" );
  return l($imagetag, $node->field_url[0]["value"], array('attributes' =>array('class' => $class, "target" => "_blank"), 'html' => TRUE));
  #return l($imagetag, $path, array('attributes' => array('class' => $class), 'html' => TRUE));
}
