Post Expiry based on custom field [Solution!]

Slickorange, thank you so much for posting this! I’m trying to do a similar thing, and I was wondering if you had any ideas of how to modify your code to get it to work for my case.

My posts are created through Gravity Forms, and thus have custom fields made by GF. I currently have a custom field titled ‘Date’ in the format of mm/dd/yyyy. I’m trying to set the expiration date based on this field. Any chance in the kindness of the heart you can try to help? Currently this code is not working at all–I’m new to developing in WordPress so I’m sure I’m missing something important here.

//My attempt at dynamically setting the expiration date of posts
//Here we go...let's see what we can make happen here
function set_expiration($post_id) {
	//Remove the default expiration date
	remove_action('save_post', 'expirationdate_update_post_meta');
	//Pull the date we need
	$date = get_post_meta( $post_id , 'Date', true );

	expirationdate_update_post_meta_gig($post_id, $date);
}

function expirationdate_update_post_meta_gig($id, $date) {
    // don't run the echo if this is an auto save

    if ( defined('DOING_AUTOSAVE') && DOING_AUTOSAVE ) {
        return;
    } else {
    //'m/d/Y' is the format my ACF date field is outputting - can be differ from each setup!
        $formatted_date = DateTime::createFromFormat('m/d/Y', $date);

        $month	 = intval($formatted_date->format('m'));
        $day 	 = intval($formatted_date->format('d'));
        $year 	 = intval($formatted_date->format('y'));

        //I am not using time in my ACF field, so I am setting it manually to the end of the day.
        $hour 	 = 23;
        $minute  = 59;

        $opts = array();
        $ts = get_gmt_from_date("$year-$month-$day $hour:$minute:0",'U');

        // Schedule/Update Expiration
        $opts['expireType'] = 'draft';
        $opts['id'] = $id;

        _scheduleExpiratorEvent($id,$ts,$opts);
	}
}

add_action('gform_after_submission_1', 'set_expiration', 1);
add_action('gform_after_submission_4', 'set_expiration', 1);
add_action('gform_after_submission_5', 'set_expiration', 1);

In case if anyone is scouring the internet looking for a solution to use this plugin with Gravity Forms, here is the solution I crafted. Thanks for the ‘codespiration’ slickorange!

function after_gig_submit($entry){
	$post_id = $entry["post_id"];

	$date = get_post_meta( $post_id, 'Date', true );

	set_expiration($post_id, $date);
}

function set_expiration($id, $date) {

	// 'm/d/Y' is the format of my GF date field
    $formatted_date = DateTime::createFromFormat('m/d/Y', $date);

    $month	 = intval($formatted_date->format('m'));
    $day 	 = intval($formatted_date->format('d'));
    $year 	 = intval($formatted_date->format('y'));

	//Manually set post to expire at the end of the day.
    $hour 	 = 23;
    $minute  = 59;

    $ts = get_gmt_from_date("$year-$month-$day $hour:$minute:0",'U');

	$opts = array(
		'expireType' => 'draft',
		'id' => $id
	);

    _scheduleExpiratorEvent($id, $ts, $opts);
}

//Add the action hooks for each form that can post gigs
add_action('gform_after_submission_1', 'after_gig_submit', 1);
add_action('gform_after_submission_4', 'after_gig_submit', 1);
add_action('gform_after_submission_5', 'after_gig_submit', 1);

Hi there, how would i get this to work with a drop down option. I have been rattling my brain for a solution and this is the closest thing i’ve seen to what i am trying to achieve.

In my site I’m using gravity forms for users to create their advertisements/posts.
I want it so a user will choose their listing expiry from the drop down options of 1 week, 2 weeks, 1 month etc..

I am confident with WP development theme development but nothing like this! Any help would be great.

Thank you for your solution WillPac!

Where i must put this code? Plz help!

Awesome!
