This code enables you to print all the values for a specific custom field. In this example, the custom field name is key_1.
add_action( 'loop_start', 'your_function' );
function your_function() {
if ( is_singular('post') ) {
$key = get_post_custom_values( 'key_1' );
foreach ( $key as $value ) {
printf( '%s<br>', $value );
}
}
}The code uses the foreach PHP function with get_post_custom_values.
Use this code when you want to display all custom field values.
Here’s the backend setup for each custom field used in this example:
In The Loop
Use this code to avoid any loops added to the sidebars like the Genesis Featured Posts widget or related featured type widgets.
add_action( 'loop_start', 'your_function' );
function your_function() {
if ( is_singular('post') && in_the_loop() ) {
$key = get_post_custom_values( 'key_1' );
foreach ( $key as $value ) {
printf( '%s<br>', $value );
}
}
}
