I have a custom content type which has a field called "location" which is a long select list (100 or so items). I want to get an array of all locations which have a piece of content associated with them. The numeric value of this field is stored in content_type_[my_content_type], but I can't find anywhere in the database where the name of the values are stored. I hope that's not too confusing - just to be clear, I want to do something like this:
SELECT DISTINCT(field_location_value) FROM content_type_[my_content_type]
and then
SELECT field_location_name_or_something FROM where_on_earth_are_the_names_stored
and then do something with the two arrays to find the names I want.
Can anyone help?
Thanks a lot. Drupal 6, by the way.
If you mean select list field of CCK:
Get all location associated with current node (piece of content?):
$node = node_load('YOUR content ID');
print_r($node->field_location); // $node->field_location - this will array of values.
Get all values of that field (defined in "Allowed values"):
$content_field = content_fields('field_location');
$allowed_values = content_allowed_values($content_field); // array of values
I found this, after much trial and tribulation, in the database table content_node_field_instance, under the field's widget settings field.
This Drupal 6 code snipped will retrieve your cck field value options and put them in the $allowed_values variable as an array. Replace 'YOUR_CCK_FIELD_NAME' with your cck field name (name, not label)
$cck_field_name = 'YOUR_CCK_FIELD_NAME';
$cck_field = db_fetch_object(db_query("SELECT global_settings FROM {content_node_field} WHERE field_name = '%s'", $cck_field_name));
$cck_field_global_settings = unserialize($cck_field->global_settings);
$allowed_values = explode("\r\n", trim($cck_field_global_settings['allowed_values'], "\r\n"));
In Drupal 7 if you have a field of type List (text) then I have written the following function to return an array of options:
function get_drupal_select_options($field_name) {
$options = unserialize(db_query("SELECT c.data
FROM field_config_instance i
INNER JOIN field_config c ON c.id = i.field_id
WHERE i.field_name = :fieldname", array(':fieldname'=>$field_name))->fetchField());
return $options['settings']['allowed_values'];
}

im following this tutorial to implement a multi checkbox field in flask with jinja
https://gist.github.com/doobeh/4668212
It works for the most part but when I go to access the value in my code (products is the field where I used the multicheckbox) like
class CreateBoardForm(Form):
products = MultiCheckboxField(
'Select Products:',
coerce=int,
choices=[(1, 'one'), (2, 'two'), (3, 'three')])
......
if request.method == 'POST':
products=request.form['products']
print name, description, tags
print "Selected products:", products
When I print selected products I only see one value being selected. When I printed the forms object I see this python data structure ImmutableMultiDict([('products', u'1'), ('products', u'3')])
Im not sure how to get all the values for the 'products' key
you will have to use the getlist method in order to return a list of other choices.
request.form.getlist('products')
i am creating a program with asp.net and using entity framework for sql server
MyEntitiesCONF db = new MyEntitiesCONF();
var query = (from p in db.f
join q in db.members
on p.friend_id equals q.ID
where p.uid == 1
select new
{
name = q.Name,
id = p.friend_id,
}).ToArray();
when i execute the query, i will get a {<>f__AnonymousType1[6]}
which means it is an anonymous type with 6 returns( each one have 2 field name and id )
so it is something like an 2d array
this is my question, how i can use this 2d data?
i want dynamically use each 6 ID field somewhere and name fields in other places,
any idea?
and another question, how can i get a array list, not an anonymous type
thanks
I want to sort data in repository based on the content of a specific field
For example i have an entity person with the fields role,fistName and lastName.
I would like to sort using ->orderBy('p.role', ???) and get a list ordered based on this order : professors then directors then teachers and at last students .
Example of my database:
Wanted result:
Ps: i can not use ASC or DESC since my sorting order is neither ASC nor DESC;
it is a custom order
Very strage scenario, you could use a CASE statement in order to assing a custom value for each fields then sort on him.
You could use the HIDDEN keyword.
As example take a look at this DQL:
SELECT p, CASE
WHEN p.role = "professor" THEN 1
WHEN p.role = "director" THEN 2
WHEN p.role = "teacher" THEN 3
WHEN p.role = "student" THEN 4
ELSE 99 END
AS HIDDEN mySortRule
FROM Bundle\Entity\Person p
ORDER BY mySortRule ASC
Hope this help
I have an enquiry form which works from a view with a custom query. The form has filters, which I use in the executeQuery method of the view on the form to add ranges on various fields.
A new requirement is to filter based on two fields in the query.
Example: The PurchLine table is one of the tables in the query.
A new range is needed :
if PurchLine.ItemId != “” then
filter by PurchLine.PurchStatus == None
but, if the Item has a SPECIFIC value,
then filter by PurchStatus == Received.
(Ok, this is just an example!).
I am unable to modify my query to add a range on the PurchStatus based on the Item field.
I know exactly how the string value of the query must look, but how can I modify the query string?
The current query string looks like this (if I breakpoint on super in executeQuery):
SELECT FIRSTFAST * FROM OpenPOLinesView(OpenPOLinesView) WHERE ((CreatedDateTime<='2016-11-30T23:59:59')) AND ((VendAccount = N'S000001048'))
I want to add this at the end:
AND (((ItemId = N'') AND (PurchStatus = 0)) OR ((ItemId = N'XXX123') AND (PurchStatus = 2)))
How can I modify the query string in code?
You can use query expression for this, e.g.
queryBuildRange.value(strFmt('((%1 == %2) || ((%1 == %3) && (%4 == "%5")))',
fieldStr(InventTable, ItemType),
any2int(ItemType::Service),
any2int(ItemType::Item),
fieldStr(InventTable, ProjCategoryId),
queryValue("Spares")));
Please refer to this link Using Expressions in Query Ranges [AX 2012] for details.
In Drupal, I can execute a SQL as follows:
$query_object = db_query("SELECT * FROM {nodes}");
If I know the query returns only a single result (so only 1 row and 1 column), I can directly fetch it with:
$result = db_result($query_object);
If I got multiple results, I need to loop through them with something like:
$rows[] = array();
while (($row = db_fetch_object($query_object) != FALSE) {
$rows[] = $row;
}
I'm wondering if there is an easier way to do that? Is there a way that I can transfer all results into an array with a single statement? Or isn't that working, because db_result returns a cursor-like object, where you can only fetch a single row each time?
Not in Drupal 6.
In Drupal 7, there are fetch methods that can help to avoid loops like that. From http://drupal.org/node/310072:
<?php
// Retrieve all records into an indexed array of stdClass objects.
$result->fetchAll();
// Retrieve all records into an associative array keyed by the field in the result specified.
$result->fetchAllAssoc($field);
// Retrieve a 2-column result set as an associative array of field 1 => field 2.
$result->fetchAllKeyed();
// You can also specify which two fields to use by specifying the column numbers for each field
$result->fetchAllKeyed(0,2); // would be field 0 => field 2
$result->fetchAllKeyed(1,0); // would be field 1 => field 0
// Retrieve a 1-column result set as one single array.
$result->fetchCol();
// Column number can be specified otherwise defaults to first column
$result->fetchCol($column_index);
?>
In Drupal 7, you can also use:
db_query('QUERY')->fetchAll(PDO::FETCH_ASSOC);
I do always something like this ( just a simple exemple) :
$query = db_query("SELECT nid
FROM {from}
WHERE blallala
",
$tab_arg
);
if ($query->rowCount() == 0) {
$output=t('no result')
} else
{
foreach($query as $result)
{
$tab_res[]=$result;
}
foreach($tab_res as $res)
{
$output.=$res->nid;
}
}
One can also use db_fetch_array($result), where $result =db_query($queryString). As explained from the Drupal documentation:
[It returns] ...an associative array representing the next row of the result, or
FALSE. The keys of this object are the names of the table fields
selected by the query, and the values are the field values for this
result row.
