drupal views: how to invoke swftools media player for emfields? - drupal-6

Question

I am using swftools to display filefields (Drupal 6).
Now I would like to use swftools to display the custom-url emfields (embedded media fields). For example, if my emaudio field contains the url http://example.com/myaudio.mp3. I would like to use the swftools audio player to play this mp3 file.
I know how to invoke the swftools player, if I am displaying a node that contains an emfield. I use hook_preprocess_content_field() to replace $items[0]['view'] with swf($items[0]['value']):
function mytheme_preprocess_content_field(&$vars) {
foreach ($vars['items']as $index=>$arr){
// Note:
// Emfield's custom_url video provider is called "zzz_custom_url".
// Emfield's custom_url audio provider is called "custom_url"
if ($arr['provider']=='zzz_custom_url' || $arr['provider']=='custom_url'){
$vars['items'][$index]['view'] = swf($arr['value']);
}
}
}
But I do not know how to invoke the swf player if I am displaying a view that contains an emfield. That is, I have not been able to figure out how to pull off a similar trick when I am displaying a view rather than a node. Any suggestions?

Answer 1

I have a solution.
I created a views template to theme my emaudio field,
views-view-field--field-my-emaudio-embed.tpl.php
Here is the content of the template:
$data = $row->{$field->field_alias};
print swf($data);

Another solution:
Create the custom formatter "SWF Emaudio", as described below. Then select this formatter to display your custom-url emaudio field, from within the cck or views UI.
function mymodule_field_formatter_info() {
$formatters = array();
$formatters['swf_emaudio'] = array(
'label' => t('SWF Emaudio'),
'field types' => array('emaudio'),
);
}
function mymodule_theme() {
$themes['mymodule_formatter_swf_emaudio'] = array(
'arguments' => array('element' => NULL, 'options' => array()),
'function' => 'theme_o4_mediatools_formatter_swf_emaudio',
);
}
return ($themes);
}
function theme_mymodule_formatter_swf_emaudio($element, $options = array()) {
$embed_value = $element['#item']['value'] ;
$output = swf($embed_value, $options);
return ($output);
}
