To me it seems Picture_Template
is worthless – it’s not even correctly formed (you need to place run-time code in a constructor).
Plus you also seem to lack the basic understanding of variable scope (like accessing $post
and $obj
within functions and classes, without globalising them first).
Here is what I think you’re trying to do;
function test_picture()
{
$picture = new Picture( get_the_ID() );
$picture_result = $picture->embed();
/* debugging */
echo '<pre>';
var_dump( $picture );
var_dump( $picture_result );
echo '</pre>';
}
function play_button()
{
echo get_play_button();
}
function get_play_button()
{
$picture = new Picture( get_the_ID() );
if ( $embed = $picture->embed() ) {
// do something & return something
}
return null; // return nothing if embed failed
}
