Add ACF to existing array

How do I add an advanced custom field to en existing array (this is the Recent Posts Extended Widget)? I have the ACF, titled ‘start-date’ and I know I want to add it in where it says ‘<h3>’start-date'</h3> or below the ‘title’ below, but I’m not sure what the correct syntax would be, or if/how to add the arg to the list in the array. The php syntax I usually use is not working in this case. Please help!

Here is my code:

`$defaults = array(
‘title’ => esc_attr__( ‘Recent Posts’, ‘rpwe’ ),
‘title_url’ => ”,

‘limit’ => 5,
‘offset’ => 0,
‘order’ => ‘DESC’,
‘orderby’ => ‘date’,
‘cat’ => array(),
‘tag’ => array(),
‘taxonomy’ => ”,
‘post_type’ => array( ‘post’ ),
‘post_status’ => ‘publish’,
‘ignore_sticky’ => 1,

‘excerpt’ => false,
‘length’ => 10,
‘thumb’ => true,
‘thumb_height’ => 45,
‘thumb_width’ => 45,
‘thumb_default’ => ‘http://placehold.it/45×45/f0f0f0/ccc’,
‘thumb_align’ => ‘rpwe-alignleft’,
‘date’ => true,
‘date_relative’ => false,
‘readmore’ => false,
‘readmore_text’ => __( ‘Read More »’, ‘rpwe’ ),

‘styles_default’ => true,
‘css’ => $css_defaults,
‘cssID’ => ”,
‘css_class’ => ”,
‘before’ => ”,
‘after’ => ”

);

// Allow plugins/themes developer to filter the default arguments.
return apply_filters( ‘rpwe_default_args’, $defaults );

}

/**
* Outputs the recent posts.
*
* @since 0.9.4
*/
function rpwe_recent_posts( $args = array() ) {
echo rpwe_get_recent_posts( $args );
}

/**

function rpwe_get_recent_posts( $args = array() ) {

// Set up a default, empty variable.
$html = ”;

// Merge the input arguments and the defaults.
$args = wp_parse_args( $args, rpwe_get_default_args() );

// Extract the array to allow easy use of variables.
extract( $args );

// Allow devs to hook in stuff before the loop.
do_action( ‘rpwe_before_loop’ );

// Display the default style of the plugin.

// Perform the query.

return $posts;

}`

Would I add something like this to the bottom section:

if ( $args[‘start-date’] ) :
$html .= ‘<a href=”‘ . esc_url( get_permalink() ) . ‘”>’ . $args[‘start-date’] . ‘</a>';

If so, how would I add the ACF ‘start-date’ to the args in the first section?

Thanks in advance!

Hi @driscoll62gmail-com,

Thanks for the post.

To get values from an ACF field, you will only need to make use of the get_field() function when calling the value of the $args[] parameter.

If the field is located within a widget, you might need to add a second parameter, this would be a string containing the the word ‘widget_’ and the widget’s ID in the following format; “widget_{$widget_id}”
