looking for a good way to query posts on a list of specific days. tryi WordPress

  • SOLVED

looking for a good way to query posts on a list of specific days. trying to create a total count for each user based on a list of dates. I get passed the following array with details.

id = user id
count = total number of dates
dates = array of dates.

1. The maximum number of dates would be 31 as days don't repeat.
2. I can't do a date range as I need to gather specific totals of posts for a user on the list of dates.
3. I could have between 1-20 users, with a maximum of 31 dates each.
4. Each date could have 0 to 20 posts.
5. I'm adding the total of these posts on each day together for each user.
6. date format is m/d/y

Example: [6] => Array

1/27/2018 --> 6 posts
2/7/2018 --> 14 posts
so user id 4 has 20 posts.




[6] => Array
(
[id] => 4
[count] => 2
[dates] => Array
(
[0] => 1/27/2018
[1] => 2/7/2018
)

)

[7] => Array
(
[id] => 5
[dates] => Array
(
[0] => 1/20/2018
[1] => 1/28/2018
[2] => 2/10/2018
)

)

Is it possible you can show me your site ?

No I have everything run locally, I'm basically wanting to do a query on each of the dates for each user to find the total posts. I would just like to avoid all sorts of nested loops.

Hello,
That's code is what you need exactly and we have add it to our demo site and working very good


/**
* Your requested function
*/

$value = array();
$output = array();

foreach( get_users() as $user ){
$dates = array();
$posts = get_posts( array('author' => $user->ID, 'posts_per_page' => -1) );
foreach($posts as $p){
$date = date('m/d/Y', strtotime($p->post_date));
if( !in_array($date, $dates) ){
array_push($dates, $date);
}
}

$value['id'] = $user->ID;
$value['count'] = count($dates);
$value['dates'] = $dates;

array_push($output, $value);
}

print_r( $output);



This is the output
_______________

Array
(
[0] => Array
(
[id] => 1
[count] => 7
[dates] => Array
(
[0] => 02/17/2018
[1] => 1/16/2018
[2] => 12/5/2017
[3] => 11/15/2017
[4] => 10/29/2017
[5] => 10/19/2017
[6] => 09/19/2017
)
)
[1] => Array
(
[id] => 2
[count] => 5
[dates] => Array
(
[0] => 02/17/2018
[1] => 02/16/2018
[2] => 02/15/2018
[3] => 01/15/2018
[4] => 12/19/2017
)
)
)

Here's one way, if I understand correctly, if you want to use the date query in WP_Query:

We define this helper function:

/**
* Helper function - Number of posts per user
*
* @uses WP_Query
*
* @param int $user_id User ID. Default 0.
* @param array $dates Array of m/d/y dates. Default empty.
* @return int $return Number of found posts.
*/
function wpq_post_count_per_user( $user_id = 0, $dates = [] ) {
$args = [
'fields' => 'ids',
'author' => (int) $user_id,
'nopaging' => true,
'ignore_sticky_posts' => true,
'date_query' => [
'relation' => 'OR',
],
];
foreach( (array) $dates as $date ) {
$args['date_query'][] = [
'year' => date( 'Y', strtotime( $date ) ),
'month' => date( 'm', strtotime( $date ) ),
'day' => date( 'j', strtotime( $date ) ),
];
}
$query = new WP_Query( $args );
return $query->found_posts;
}


Usage example:

$input = [
[
'id' => 1,
'count' => 3,
'dates' => [
'1/20/2018',
'1/22/2018',
'1/18/2018',
],
],
[
'id' => 2,
'count' => 3,
'dates' => [
'1/28/2018',
'1/29/2018',
'1/30/2018',
],
],
];

// Number of posts for a given user
echo wpq_post_count_per_user( $input[0]['id'], $input[0]['dates'] );


Hope it helps.

$date_start = '2018-01-01';
$date_end = '2018-01-31';

$res = $wpdb->get_results( $wpdb->prepare("
select count(ID) `count`, post_author, DATE(post_date) as day, DATE_FORMAT(post_date, '%c/%e/%Y') nice_day
from {$wpdb->prefix}posts
where
post_date>=%s and post_date<=%s
and post_type='post' and (post_status='publish' OR post_status='private')
group by post_author, day
order by day, post_author",
$date_start, $date_end
));

$users = array();
foreach ( $res as $row )
{
if ( !isset( $users[ $row->post_author ] ) )
$users[ $row->post_author ] = array(
'id' => $row->post_author,
'count' => 0,
'dates' => array(),
);

$users[ $row->post_author ]['count']++;
$users[ $row->post_author ]['dates'][] = $row->nice_day;
}
$users = array_values( $users );


So the $users contains list as you need. It's simple to add count of posts to the list, but you do not specified where it should be is.
