Hi
i need the following sql query into cakephp find() format. the query it self is working fine but i need to change it.
$this->Part->query(
"SELECT `parts`.`id`,`parts`.`part_name`
FROM `parts`
LEFT JOIN (
SELECT `op` . *
FROM `order_parts` AS `op`
WHERE `op`.`order_id` =".$this->Session->read('orderid')."
) AS `vT`
ON ( `parts`.`id` = `vT`.`part_id` )
WHERE `vT`.`part_id` IS NULL"
);
thanks
If your relationship are Order HABTM Part and you have a table orders_parts with columns: id, order_id,part_id you should be able to do something like this:
First, get the ids of the parts which are in the order:
//each Part has one OrdersPart per order
$this->Part->bindModel(array('hasOne' => array('OrdersParts')));
$parts = $this->Part->find('list', array(
'fields' => array('Part.name'),
'conditions' => array(
'OrdersParts.order_id' => $this->Session->read('orderid'),
),
'recursive' => 2
));
Now get the parts which are not in the order:
$this->Part->find('all', array(
'conditions' => array(
"NOT" => array('Part.id' => array_keys($parts))
),
));

I have a comparative set of arguments for WP_Query involving a custom field.
On a page I need to say "Are there going to be results?, if so display a link to another page that displays these results, if not ignore" There are between 500 and 1200 posts of this type but could be more in the future. Is there a more efficient or direct way of returning a yes/no to this query?
$args = array(
'post_type' => 'product',
'posts_per_page' => -1,
'meta_query' => array(
array(
'key' => 'partner',
'value' => $partner,
'compare' => 'LIKE',
),
),
);
$partner_query = new WP_Query($args);
if ($partner_query->have_posts() ) { [MAKE LINK] }
The link is not made from data returned, we already have that information.
Perhaps directly in the database. My SQL is not up to phrasing the query which in English is SELECT * from wp_posts WHERE post_type = 'product'} AND (JOIN??) post_meta meta_key =
partner AND post_id = a post_id that matches the first part of the query.
And if I did this, would this be more efficient that the WP_Query method?
Use 'posts_per_page' => 1 and add 'no_found_rows' => true and 'fields' => 'ids'. This will return the ID of a matching post, and at the same time avoid the overhead of counting all the matching posts and fetching the entire post contents. Getting just one matching post id is far less work than counting the matching posts. And it's all you need.
Like this:
$args = array(
'post_type' => 'product',
'posts_per_page' => 1,
'no_found_rows' => true,
'fields' => 'ids',
'meta_query' => array(
array(
'key' => 'partner',
'value' => $partner,
'compare' => 'LIKE',
),
),
);
$partner_query = new WP_Query($args);
if ($partner_query->have_posts() ) { [MAKE LINK] }
no_found_rows means "don't count the found rows", not "don't return any found rows". It's only in the code, not the documentation. Sigh.
I have this SQL query that I need to convert to CakePHP. I used this website [http://dogmatic69.com/sql-to-cakephp-find-converter][1] that converts the code but I doesn't work in the way that I want. There is no results.
I think it is because it creates an empty array
here is the SQL code :
SELECT shops.phone1 FROM galleries , albums , shops
WHERE galleries.album_id = albums.id and albums.shop_id = shops.id and galleries.id = 210
and this is the result the website gives me :
$options = array(
'fields' => array(
'shops.phone1',
),
'joins' => array(
array(
),
),
'conditions' => array(
'Gallery.album_id = albums.id',
'albums.shop_id = shops.id',
'Gallery.id' => '210',
),
);
$data = $this->find('all', $options);
but the code doesn't work.
Any Ideas what could be wrong ?
Thanks
There are many ways to achieve this.
If you have defined your associations correctly then you can do this:
$data = $this->Shops->find('all')
->contain(['Galleries','Albums'])
->fields(['Shops.phone1'])
->where(['Galleries.id' => 210]);
Otherwise you can use custom join to generate your query:
$data = $this->Shops->find('all')
->join([
'albums' => [
'table' => 'albums',
'type' => 'INNER', // define your join type here
'conditions' => 'albums.shop_id = Shops.id',
],
'galleries' => [
'table' => 'galleries',
'type' => 'INNER', // define your join type here
'conditions' => 'galleries.album_id=albums.id',
]
])
->select(['Shops.phone1'])
->where(['galleries.id' => 210]);

In CakePHP I am trying to make it so that I can count how many instances there are (in this case searchterm) that I can only select that term if there are more than 10 instances.
I have tried this:
$results = $this->Search->find('all',
array('fields' => array('Search.searchterm'),
'conditions' => array(
array('Search.searchterm LIKE' => $this->request->query['term'] . '%'),
array('count(Search.searchterm)' => '10'),
),
'group' => array('Search.searchterm'),
'limit' => 15,
));
So in this example I am trying to select all search terms where there are 10 instances but I can't get it to work.
Is it possible?
Do a find('count') instead:
$results = $this->Search->find('count',
'conditions' => array(
array('Search.searchterm LIKE' => $this->request->query['term'] . '%'),
),
));
And read the manual about the finds.
I'm having troubles to generate an sql query with operators.Actually wirte this code:
$args = array(
'post_type' => 'listings',
'posts_per_page' => 10,
'paged' => $paged,
'meta_query' => array(
//CITY
array(
'key' => 'city',
'value' => $city,
'compare' => 'LIKE'
),
//type
array(
'key' => 'type',
'value' => $type,
'compare' => 'LIKE'
),
//PRICE
array(
'key' => 'price',
'value' => array( 100, 5000 ),
'compare' => 'BETWEEN'
),
)
);
This code work fine, but now, i need to get the posts with price between $start and $end, OR price = -1. In other words, post that not have set the price, or set to -1 must show in the query. The others conditions (city, type,etc) must be match with AND
Any ideas? Thanks!
My initial thought is to add a filter onto posts_where or posts_join to inject a custom SQL condition into the query.
Something along these lines:
wp_postmeta.meta_key='price' AND
(wp_postmeta.meta_value='-1' OR
CAST(wp_postmeta.meta_value AS INT) BETWEEN $start AND $end)
I have the following model:
$values = $this->PtlUserdata->find('all', array(
'fields' => array(
'PtlUserdata.field',
'PtlUserdata.value',
'PtlUserdata.timestamp'
),
'conditions' => array(
'PtlUserdata.user_id' => $user->get('id'),
),
'order' => array('PtlUserdata.timestamp' => 'DESC'),
'group' => array('PtlUserdata.field')
));
I'm trying to order the results by timestamp and then group the results by field, so I can get the most recent record with that field name.
Does anybody know how to do this is cakephp?
Thanks in advance for any help, much appreciated :)
This is the default behavior for the database. You will have to come up with some sort of workaround to do it.
An idea: CakePHP: Group by ID and Order by date
Does this work:
$values = $this->PtlUserdata->find('all', array(
'fields' => array(
'PtlUserdata.field',
'PtlUserdata.value',
'max(PtlUserdata.timestamp)'
),
'conditions' => array(
'PtlUserdata.user_id' => $user->get('id'),
'PtlUserdata.timestamp' => 'max(PtlUserdata.timestamp)',
),
'group' => array(
'PtlUserdata.field',
'PtlUserdata.timestamp'
)
));
I haven't had the chance to test this but you definitely need to be grouping by PtlUserdata.timestamp.
