How to auto update acf field based on posting date? - php

Question

I have a custom post called Project.
I need to automatically update a field with 100 when the post date is over 7 days.
I tried the following coed in function.php but it doesn’t auto update the field.
Would you please let me know how to fix the code?
function update_active_based_on_date() {
// query to get all custom posts - project
$args = array(
'post_type' => 'project',
'posts_per_page' => -1
);
$query = new WP_Query($args);
// if posts are returned and more than 7days, update infosubmit field
if ($query->have_posts()) {
global $post;
$timestamp = get_the_time( 'U', $post->ID );
$diff = current_time('timestamp') - $timestamp;
while ($query->have_posts() && $diff > 604800) {
$query->the_post();
$field_key = "field_60836f942ae12";
$value = "100";
update_field($field_key, $value, $post->ID);
} // end while have_posts
wp_reset_postdata();
} // end if have_posts
} // end function
Thank you.

You can achieve this like:
function update_active_based_on_date() {
// query to get all custom posts - project
$args = array(
'post_type' => 'project',
'posts_per_page' => -1
);
$query = new WP_Query($args);
if ($query->have_posts()) {
global $post;
while ($query->have_posts()) {
$query->the_post();
// if posts are returned and more than 7days, update infosubmit field
$diff = time() - strtotime(get_the_date());
if($diff > 604800){
$field_key = "field_60836f942ae12";
$value = "100";
update_field($field_key, $value, $post->ID);
}
} // end while have_posts
wp_reset_postdata();
} // end if have_posts
} // end function
add_action('init','update_active_based_on_date');
