wordpress 3.0 php custom fields issue

Question

This worked perfectly in a previous version of wordpress, different site tho. I have a custom field called flash on several wp pages but it keeps defaulting to "printed if results are empty". Any ideas on why this wouldn't work?

<?php 
if ( function_exists('get_post_custom_values') ) 
  {    
   $mykey_values = get_post_custom_values('flash');
   if(count($mykey_values) > 0)
    {

foreach ( $mykey_values as $key => $value ) 
 { 
  echo "$value";


 }
    }
   else
    {
     //printed if results are empty
   echo("mainPage.swf");
    } 

  } 
 else
  {
   //printed if function doesn't exist
   echo("mainPage.swf");
  }
?>

As a test, try specifying a post ID that you know has this custom field populated: get_post_custom_values('flash', $known_post_id); — Pat

agreed with Pat, the API considers the post id as required; or it'll default to post id = 0 and you'll get zero content. — rexposadas

Hi not really sure why that is not working (as long as you are sure you do have custom fields with 'flash' values in the post). Anyhow, try the following, I am sure the following will work.

<?php
  $custom_fields = get_post_custom();
  $my_custom_field = $custom_fields['flash'];
  foreach ( $my_custom_field as $key => $value )
    echo $key . " => " . $value . "<br />";
?>
