Ok so i am trying to use WordPress's custom fields and have them working but now i have some php code i need help with.
<a href="<?php echo get_post_meta( $post->ID, '_ct_text_4dc9e9f74d000', true ); ?>">Go To Store!</a>
The above code is what i have for right now. Is there a way to setup a if and else statement so if there is a value in the custom field then show that but else show N/A if there is no value present
You mean something like this?
$customhref = get_post_meta( $post->ID, '_ct_text_4dc9e9f74d000', true );
if ( $customhref ) {
?>
<a href="<?php echo $customhref; ?>">Go To Store!</a>
<?php
} else {
echo 'N/A';
}
Chip's answer is great (and earned a +1), but just as an alternative as you are learning PHP, I prefer this style as it takes only a single line in the file that I will use and integrates better with the flow of the HTML.
<?php if(get_post_meta( $post->ID, '_ct_text_4dc9e9f74d000', true )) : ?>
<a href="<?php echo get_post_meta( $post->ID, '_ct_text_4dc9e9f74d000', true ); ?>">Go To Store!</a>
<?php else : ?>
N/A
<?php endif; ?>
Again, this is just a matter of preference and it might be helpful for you to see other ways to do the same thing.
get_post_meta twice. You could assign the result in the first if to shorten and optimize code a bit: if ($x = get_post_meta($post->ID, 'field', TRUE)) { echo $x; } else { }
<?php $custom_field = (string) get_post_meta( $post->ID, "XYZ", true ); echo str_replace(' ', '', $custom_field); ?>
