Problem with if/else custom field

    The following code works if I add a value to the custom field but when I delete the value, instead of showing nothing, I’m left with ‘From ￡’.

    <?php
$values = get_post_custom_values("treatment_price");
if ( is_array($values) ) {
echo '<h3><strong>From ￡' . $values[0]. '</strong></h3>';
}
else {
 echo '';
}
?>

    What’s wrong?

    Thanks

    Thanks for the reply, Esmi. I’m afraid it still doesn’t work for some reason. To clarify, I’m using:

    <?php
if ( get_post_custom_values("treatment_price") ) :
$values = get_post_custom_values("treatment_price");
echo '<strong>￡' . $values[0]. ' per treatment</strong>';
else :
 echo '';
endif;?>

    If I enter 10 as the value, i get ‘￡10 per treatment’, but then if I delete the 10 from the field, I’m left with ‘￡ per treatment’.

    Any ideas?

    try:

    <?php
if ( !empty (get_post_custom_values("treatment_price") ) ) :
$values = get_post_custom_values("treatment_price");
echo '<strong>￡' . $values[0]. ' per treatment</strong>';
else :
 echo '';
endif;?>

    Works on arrays too, if that’s what being returned:

    https://php.net/manual/en/function.empty.php

    $values = get_post_meta($post->ID, 'treatment_price', true);
if ($values){
echo '￡ ';
echo $values;
echo ' per treatment ';
}

    Dang… over complicated it. It was a long, late night! Good catch YouON.
