I would like to get the separate value url placed on meta_key , I have a custom field "Custom file" called mp3 then put the mp3 multiple fields would like to pick url of each value
this code below shows the url only of the last mp3 added:
<?php $minha_variavel = get_post_meta($post->ID, 'mp3', true); ?>
<?php if ($minha_variavel): ?>
<?php echo wp_get_attachment_url($minha_variavel); ?>
<?php endif; ?>

Adding what colleagues commented on your question the code would look like this:
$minha_variavel = get_post_meta($post->ID, 'mp3'); // O terceiro parâmetro é FALSE por padrão
foreach ($minha_variavel as $arquivo) { // Segundo a documentação o retorno é sempre um array
echo wp_get_attachment_url($arquivo);
}
It is printed the URL of the files but I would like to pick separate example: url of value 2 only of the second file placed in meta_key ha since thank you very much for the force of vcs

get_post_meta()receives a boolean parameter called single, that determines whether the function return is a single value or an array of values. In your case, you are calling the function with that value astrue. Try to leave it asfalse.– Caio Felipe Pereira
Good morning ! set to false now displayed nothing in case I have to put the code inside a loop or not in case it is a field with multiple volumes

$minha_variavelfor an array, you will have to traverse it in a loop– Caio Felipe Pereira
