I have a meta field called date & I need to query all records where that timestamp is equal to or less than today...
<?php
$time = time();
$querystr = "
SELECT wposts.*
FROM $wpdb->posts wposts, $wpdb->postmeta wpostmeta
WHERE wpostmeta.meta_key = 'date'
AND wpostmeta.meta_value <= $time
";
$pageposts = $wpdb->get_results($querystr, OBJECT);
?>
You could try something like this :
$today = date('Y-m-d');
$querystr = "
SELECT *
FROM wp_posts, wp_postmeta
WHERE wp_posts.ID = wp_postmeta.post_id
AND wp_postmeta.meta_key = 'date'
AND wp_posts.post_status = 'publish'
AND wp_posts.post_type = 'post'
AND STR_TO_DATE(wp_postmeta.meta_value, '%Y/%m/%d') <= '$today'
ORDER BY STR_TO_DATE(wp_postmeta.meta_value, '%Y/%m/%d') ASC
";
$custom_loop = $wpdb->get_results($querystr, OBJECT);
In the last two lines of the que query, you have to specify the format of your date (in your custom field "date"). For example if your custom "date" field has a dd/mm/YYYY format you would use :
AND STR_TO_DATE(wp_postmeta.meta_value, '%d/%m/%Y') <= '$today'
ORDER BY STR_TO_DATE(wp_postmeta.meta_value, '%d/%m/%Y') ASC
The $today date has to be Y-m-d because it's the default time format, used for the comparison by mysql.

I have an ACF repeater field (publications) with 2 sub-fields.
title and year.
I need to select from the database all titles from all posts matching a condition (let’s say all titles which include ‘search-term’) but I need the result sorted by the year (the 2nd sub-field).
This is the query I use to fetch the titles.
function get_search_results(): array
{
global $wpdb;
$sql = "SELECT pm.meta_value title, pm.post_id post
FROM {$wpdb->posts} p
JOIN {$wpdb->postmeta} pm ON p.ID = pm.post_id
WHERE p.post_status = 'publish'
AND pm.meta_key LIKE 'publication_%_title'
AND pm.meta_value LIKE '%search-term%';";
return $wpdb->get_results($sql, ARRAY_A);
}
How can I sort the results by the year?
This is the solution I came up with.
Only 2 SQL queries.
function get_search_results(): array
{
global $wpdb;
// Get publication titles.
$sql = "SELECT pm.meta_key, pm.meta_value title, pm.post_id researcher
FROM {$wpdb->posts} p
JOIN {$wpdb->postmeta} pm ON p.ID = pm.post_id
WHERE p.post_status = 'publish'
AND pm.meta_key LIKE 'publication_%_title'
AND pm.meta_value LIKE '%search-term%';";
$titles = $wpdb->get_results($sql, ARRAY_A);
// Get list of post IDs.
$researcher_ids = implode(', ', array_unique(array_column($titles, 'researcher')));
// Get publication years.
$sql = "SELECT REPLACE(pm.meta_key,'_year','_title') AS meta_key, pm.meta_value year, pm.post_id researcher
FROM {$wpdb->posts} p
JOIN {$wpdb->postmeta} pm ON p.ID = pm.post_id
WHERE p.post_status = 'publish'
AND pm.meta_key LIKE 'publication_list_%_year'
AND pm.post_id IN ($researcher_ids);";
$years_raw = $wpdb->get_results($sql, ARRAY_A);
$years = [];
// Reformat the publication years.
foreach ($years_raw as $year) {
$years[$year['researcher'] . '__' . $year['meta_key']] = $year['year'];
}
// Add the year field to each title.
foreach ($titles as &$title) {
$title['year'] = $years[$title['researcher'] . '__' . $title['meta_key']];
}
// Sort the array by the inner year value.
usort($titles, 'sortByInnerYear');
return $titles;
}
function sortByInnerYear($a, $b): int
{
return $b['year'] <=> $a['year'];
}
I am trying to count the total events using the following SQL query. I am using global $wpdb to echo the results and to store them into a variable.
global $wpdb;
$current_d_t = strtotime(date("y-m-d"));
$sql = "SELECT COUNT(post.ID) as eventCountUpcoming FROM wp_posts AS post LEFT JOIN wp_postmeta AS meta ON post.ID = meta.post_id WHERE post.post_type = 'ajde_events' AND meta.meta_key = 'evcal_erow' AND meta.meta_value > $current_d_t AND post.post_status = 'publish' GROUP BY post.ID";
$result = $wpdb->get_results($sql, ARRAY_A);
$result_more = $result->fetch_assoc();
$countEvent = $result_more['eventCountUpcoming'];
getting this error
Call to a member function fetch_assoc() on an array
Tried for each loop too, using the following code,
foreach ($result as $result_more){
$countEvent = $result_more['eventCountUpcoming'];
}
but getting this error:
$result = $wpdb->get_results($sql, ARRAY_A); returns an array of results.
In order to echo the results, try looping the array:
$result = $wpdb->get_results($sql, ARRAY_A);
foreach ($result as $res){
var_dump($result);
}
If you're just looking for one variable as the result. You can try using $wpdb->get_var()
global $wpdb;
$current_d_t = strtotime(date("y-m-d"));
$sql = "SELECT COUNT(post.ID) as eventCountUpcoming
FROM {$wpdb->posts} AS post LEFT JOIN {$wpdb->postmeta} AS meta
ON post.ID = meta.post_id
WHERE post.post_type = 'ajde_events'
AND meta.meta_key = 'evcal_erow'
AND meta.meta_value
> {$current_d_t}
AND post.post_status = 'publish';"
$result = $wpdb->get_var($sql);
Then $result should be your count.
Groupby shouldn't be necessary if you're just counting Post ID's
I have a problem with placeholders in $wpdb->get_results. With the code below I have all the results correctly but I have an error when I use the code sniffer
$now = current_time('mysql', true);
$allPosts = $wpdb->get_results("
SELECT DISTINCT
YEAR(post_date_gmt) AS `year`,
MONTH(post_date_gmt) AS `month`,
MAX(post_date_gmt) AS last_mod,
count(ID) AS posts
FROM
$wpdb->posts
WHERE
post_date_gmt < '$now'
AND post_status = 'publish'
AND post_type = 'post'
GROUP BY
YEAR(post_date_gmt),
MONTH(post_date_gmt)
ORDER BY
post_date_gmt DESC
");
I tried to change with %s and $now in the end but no results are shown
$allPosts = $wpdb->get_results("
SELECT DISTINCT
YEAR(post_date_gmt) AS `year`,
MONTH(post_date_gmt) AS `month`,
MAX(post_date_gmt) AS last_mod,
count(ID) AS posts
FROM
$wpdb->posts
WHERE
post_date_gmt < %s
AND post_status = 'publish'
AND post_type = 'post'
GROUP BY
YEAR(post_date_gmt),
MONTH(post_date_gmt)
ORDER BY
post_date_gmt DESC
", $now);
I know I can resolve it by omitted post_date_gmt < %s but I'd like to know how I can resolve it with post_date_gmt < %s?
I have posts where the author is assigned as Co-Author. If i want to show them on my author page, they are not listed. Because of this condition in the query:
AND (wp_posts.post_author = 53)
How can i remove it? Or is there any better solution?
public static function pre_get_posts($query)
{
if ($query->is_author() && $query->is_main_query()):
$author = (get_query_var('author_name')) ? get_user_by('slug', get_query_var('author_name')) : get_userdata(get_query_var('author'));
$authorPostIDs = self::getAuthorsPostIDs($author->ID);
$coAuthorPostIDs = self::getCoAuthorsPostsIDs($author->ID);
$postIDs = array_unique(
array_merge($coAuthorPostIDs, $authorPostIDs), SORT_REGULAR
);
$query->set('post__in', $postIDs);
$query->set('post_status', 'publish');
endif;
}
My full query:
SELECT SQL_CALC_FOUND_ROWS wp_posts.ID
FROM wp_posts
WHERE 1=1
AND wp_posts.ID IN (349956,327745)
AND (wp_posts.post_author = 53)
AND wp_posts.post_type = 'post'
AND ((wp_posts.post_status = 'publish'))
ORDER BY wp_posts.post_date DESC
LIMIT 0, 10
I used followed query in symfony2 i need to APC cache with doctrine how to use it... I tried follow apc cache but not got error.
$query = $this->getDoctrine()->getEntityManager()->getConnection()->prepare(
"SELECT V.id,
(CASE WHEN "DAY" THEN DATE_ADD( NOW() , INTERVAL start_date DAY )
WHEN "MONTH" THEN DATE_ADD( NOW() , INTERVAL start_date MONTH )
WHEN "YEAR" THEN DATE_ADD( NOW() , INTERVAL start_date YEAR )
END as startDate
) `enter code here`
FROM table_name V
WHERE V.id = :id
ORDER BY date ASC"
);
$query->bindValue('id', $id)
$query->setResultCacheDriver(new ApcCache())
$query->useResultCache(true, 300, 'testcache');
$query->execute();
$results = $query->fetchAll();
use Doctrine\ORM\Query\ResultSetMapping;
$oResultSetMapp = new ResultSetMapping;
$oResultSetMapp->addScalarResult('id', 'id');
$oResultSetMapp->addScalarResult('name', 'name');
$sqlQuery = "SELECT T.id AS id, T.enable, T.name
FROM table_name as T
WHERE T.enable = :enable";
$query = $this->getDoctrine()->getEntityManager()
->createNativeQuery($sqlQuery, $oResultSetMapp)
->setParameter('enable', 1)
->setResultCacheDriver(new ApcCache())
->useResultCache(true, 300, 'testcache');
$query->getResult();
Try this one, this will help you for sure.
