How can I get this function to return just a value, rather than an array?
$results = $newdb->get_col( "SELECT ItemID, Price FROM $table WHERE ItemID = $quanid GROUP BY Price ORDER BY COUNT(*) DESC LIMIT 1", 1 );
This is the result when I print_r( $result ); :
Array ( [0] => 40 )
This is what I need:
40
Try
$wpdb->get_var()
If you have more results than one, you'll get the first one.
Echo Sresult['0']; to print only data stored in array index 0

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
Retrieve a node based on condition:
$query = \Drupal::entityQuery('node')
->condition('type', 'my_content_type')
->condition('title', 'my node title');
$nid = $query->execute();
The result of $nid is the correct node ID but the format is a string, (es: "123")
When I want to load the node by its ID, I write:
$node_id = Node::load($nid);
Doing this, the result I get is NULL because the variable $nid is holding a string (not integer).
If I write the code like this:
$node_id = Node::load(123);
I get the node loaded.
How can I convert the variable string ($nid) as an integer ?
I tried:
$nid_int = (int) $nid;
$node_id = Node::load($nid_int);
also I tried:
$nid_int = intval($nid);
$node_id = Node::load($nid_int);
But I alwas get result NULL
Thanks for your help
You can't use Node::load($nid); directly, because the $query->execute() return an array like ['vid' => "nid"].
$query = \Drupal::entityQuery('node')
->condition('type', 'my_content_type')
->condition('title', 'my node title');
$nids = $query->execute();
$nid = (int)array_shift($nids);
Can try:-
$nid_string = $nid->__toString();
$node_id = Node::load((int) $nid_string);
I'm trying to update a certain number of rows of my entity "Vehicule". I have no idea how could it work.
I'm actually trying to modify only two rows where direction= 5.This is the function I used in order to update.
public function ValidAction(\OC\UserBundle\Entity\User $direction) {
$qb = $this->getDoctrine()
->getRepository('CarPfeBundle:Vehicule')
->createQueryBuilder('v');
$q = $qb->update ('CarPfeBundle:vehicule v')
->set('v.direction', '?1')
->where('v.direction = ?2')
->setParameter(1, $direction)
->setParameter(2, 5)
->getQuery();
$p = $q->execute();
return $this->redirect($this->generateUrl('demandeveh_afficher'));
}
But the above code update all rows of my database. I need to update only two rows. Any help please?
Try to do this ;
public function ValidAction(\OC\UserBundle\Entity\User $direction) {
$qb = $this->getDoctrine()
->getRepository('CarPfeBundle:Vehicule')
->createQueryBuilder('v');
// $ids an array that contains all ids with your condition
$ids = $qb->select('v.id')
->where('v.direction = :direction')
->setParameter(
array(
'direction' => $direction
)
)
->getQuery()
->getResult();
$id1 = $ids[array_rand($ids)];
$id2 = $ids[array_rand($ids)];
//To be sure that $id1 is different from id2
while ($id1 == $id2) {
$id2 = $ids[array_rand($ids)];
}
$q = $qb->update ('CarPfeBundle:vehicule v')
->set('v.direction', ':val1')
->where('v.direction = :val2')
->andWhere('v.id IN (:id1, :id2)')
->setParameter(
array(
'val1' => $direction ,
'val2' => 5 ,
'id1' => $id1,
'id2' => $id2,
)
)
->getQuery();
$p = $q->execute();
return $this->redirect($this->generateUrl('demandeveh_afficher'));
}
With the above code I hope you can update only two rows and randomly.
Good luck !
While a solution like Houssem Zitoun suggested may work, why not use a subquery?
If you get the (like I did, if not, just skip the middle SELECT)
Error: #1235 - This version of MySQL doesn't yet support 'LIMIT & IN/ALL/ANY/SOME subquery'
go with this answer and something like (doc): - untested
UPDATE CarPfeBundle:Vehicule v
SET v.direction = ?1
WHERE v.direction IN
(SELECT * FROM (
SELECT v.direction
FROM CarPfeBundle:Vehicule v2
WHERE v.direction = ?2 LIMIT 2
)) AS sq
I have the following tables in mysql with given relationships and same has been define in the symfony2. I want to achieve the following query which I wrote it down below. can some one help me how can I write it in querybuilder?
unitids(id,unitid,databaseid)
Mappaths(id,ref_unitid2(forigen key for unitids id) ,ref_unitid1 (forigen key for unitids id),nomal value)
traveltime(id,ref_map_path(forigen key for mappaths id), traveltime,noobjs,ondate)
my mysql query is like this :
SELECT t.ID,t.ondate, un.databaseid as source1,
un1.databaseid as desitnation, t.traveltime, t.noobjs
FROM test.traveltime t
left join test.mappaths p on t.ref_map_path = p.ID
left join test.unitids un on (p.ref_unitids1 = un.id )
left join test.unitids un1 on (p.ref_unitids2= un1.id)
where un.databaseid=50 and un1.databaseid =1 limit 1;
which give me each one row of source and destination of and objects etc like this :
in symfony2 when i run this query
$query = $em->createQueryBuilder();
$results = $query->select('un.databaseid,un1.databaseid')
->from('ApiMapBundle:Traveltime', 't')
->leftJoin('t.refMapPath', 'p')
->leftJoin('p.refUnitids2', 'un')
->leftJoin('p.refUnitids1', 'un1')
->where('un.databaseid = :bdatabaseid1')
->setParameter('bdatabaseid1', 2)
->andwhere('un1.databaseid = :bdatabaseid2')
->setParameter('bdatabaseid2',1)
//->setMaxResults(1)
->getQuery()
->getResult();
it give me output like
Array ( [0] => Array ( [databaseid] => 1 ) [1] => Array ( [databaseid] => 1 ))
but instead it should give me
Array ( [0] => Array ( [databaseid] => 1 ) [1] => Array ( [databaseid] => 2 ))
How can i achieved this above output?????
Assumed that you are writing code in Repository and you also defined relations in your Entities
$em = $this->getEntityManager();
$query = $em->getRepository('BUNDLE:traveltime')->createQueryBuilder('t');
$query->select('t.Id,..')
->leftJoin('t.ref_map_path','p')
->leftJoin('p.ref_unitids1','un')
->leftJoin('p.ref_unitids2','un1')
->where('un.databaseid = :bdatabaseid')
->setParameter('bdatabaseid',1)
->orWhere('un1.databaseid = :bdatabaseid1')
->setParameter('bdatabaseid1',2);
The following query can get all values for a custom field key. collected from: http://goo.gl/94qw3
function get_meta_values( $key = '', $type = 'post', $status = 'publish' ) {
global $wpdb;
if( empty( $key ) )
return;
$r = $wpdb->get_col( $wpdb->prepare( "
SELECT pm.meta_value FROM {$wpdb->postmeta} pm
LEFT JOIN {$wpdb->posts} p ON p.ID = pm.post_id
WHERE pm.meta_key = '%s'
AND p.post_status = '%s'
AND p.post_type = '%s'
", $key, $status, $type ) );
return $r;
}
$my_var = get_meta_values( 'YOURKEY' );
I want to get all values for a key of "custom field B"
when match a value '2010' for a key of "custom field A".
Example:
I have 2 keys (2 costom Fields)
-------------------------
Movie Yr | Artist
---------------------------
2000 | Artist One
2008 | Artist Two
2012 | Artist Three
| Artist Four
| Artist Five
---------------------------
With the above query I can get the following list.
---------
Movie Yr
---------
2000
2008
2012
---------
Now after I select value '2010' of the field "Movie Yr", I want to get a list of Artists. Not all artists but only those who are related with '2010'. Something like
---------
Artist
---------
Artist Two
Artist Four
Artist Five
---------
if i get you right here, insted of taking all the values you want to add another filter.
am i right?
if so - all you need is edit the SQL you get and add the filter you want.
this is your sql now:
SELECT pm.meta_value FROM {$wpdb->postmeta} pm LEFT JOIN {$wpdb->posts} p ON p.ID = pm.post_id WHERE pm.meta_key = '%s' AND p.post_status = '%s' AND p.post_type = '%s'
the %s is taking it's content from the variables that comes after:
$key, $status, $type
in that order.
in your case all you need to do is add the extra to the SQL query.
i would be happy to help you if you could just say what you want to do... your explanation is quite a mess.
