Is it possible to get the list of taxonomy terms in a field collection from a list of nodes using Views ?
At the moment in Views I can list the nodes from one Taxonomy term (in another vocabulary from the results I need). Each nodes have a field collection with taxonomy term. So I get something like that :
Term1 (Node1)
Term2 (Node1)
Term4 (Node2)
Term3 (Node2)
Term1 (Node3)
Term2 (Node3)
Term3 (Node3)
But I need to get the list with only one individual taxonomy term listed like this :
Term1
Term2
Term3
Term4
Any idea, with View ?
I found out...
Don't put other field than the one you need.
In the field(s) you need, don't check "Multiple field settings" and each one will be treated independently.
In "Advanced", activate "Use aggregation".
In the end that solve the problem but it appears to be a dead end for the following of what I need to do. I had to code a custom block in my module to obtain exactly what I want in the end.

I've been struggling with the following for a while and would be more than happy for some brainpower ;)
I have an Advanced filter form, which filters through orders via many different filters, currently the one that I can't make function is the following:
I have 4 controls on a form (all unbound):
ogProductType - option group that allows you to pick from 3 types of products
lbAllProducts - list box displaying all types of products. It has 2 rows, and gets filtered by tbSearchProducts which searches by the name of the product, but the lb is bound by the first row which is the product code. The filter is done by inserting criteria into the name row:
"Like "*" & [tbSearchProducts] & "*"".
tbSearchProducts - text box for searching the product by name. Has requery for lbAllProducts OnChange.
Main orders list box - lbOrders - which has many rows. The ones we care about in this case are ID; eProductCode; fProductCode; kProductCode. It is supposed to display all IDs of all orders where the filters are true (all orders where type 1 product is bought). In the query builder I have the following code as criteria for each them:
In lbOrders:
for eProductCode row
IIf([ogProductType]=1 And Len(Nz([lbAllProducts]))>0;[lbAllProducts];"")
for fProductCode row
IIf([ogProductType]=2 And Len(Nz([lbAllProducts]))>0;[lbAllProducts];"")
for kProductCode row
IIf([ogProductType]=3 And Len(Nz([lbAllProducts]))>0;[lbAllProducts];"")
I want the Main list box to be filtered depending on what type of product was chosen (eProductCode is chosen with the option group set on First option = 1; fProductCode = 2; kProductCode=3), but ignore the other 2 rows totally. Sadly, with that false statement saying the criteria for the field is "", in case it was not chosen via the option group, it doesn't work.
How can I stack 3 criteria, all taking values from the same list box, but only if option group is the right on, without them interfering with each other?
I tried with "*" in false and it doesn't work...
Any ideas?
I've solved it :)
You simply never use the criteria to filter the 3 rows... You just use the field itself to load the proper row that you need and put in criteria...
Here is the code for the field:
Expr1: IIf([obProducts]=1 And Len(Nz([lbSearchProduct]))>0;[tblOrders]![еProductCode];IIf([obProducts]=2 And Len(Nz([lbSearchProduct]))>0;[tblOrders]![fProductCode];IIf([obProducts]=3 And Len(Nz([lbSearchProduct]))>0;[tblOrders]![kProductCode])))
And in criteria for that row I set the list box that has the bound column for product code lbAllProducts
Short form of the question:
How can I set a filter for the form which is used by the "List Items Edit Form" property of a ComboBox?
Long description of the environment:
In my database, there is a growing number of structurally similar values which describe something. I collated all of these in one table named ComboTexts, and added a second table ComboTextTypes to customize the field names on the user side. Example:
ComboTexts table:
ID s1 s2 s3 TypeID
1 1 First Floor Ground Floor 2
2 2 Second Floor Null 2
3 AOX DIN 1485 determination of organic components 3
ComboTextTypes table:
ID formtitle ch1 ch2 ch3
2 Floor Floor Number Floor Name Alternate Name
3 Process Process name Standard Description
In order to edit entries in ComboTexts, I provide two forms: The form CoreData displays the list of formtitles from ComboTextTypes and an "edit" button. When the user selects a fomtitle and clicks "edit", the form EditComboTexts is called with a filter for TypeID set. EditComboTexts extracts the TypeID from its filter and modifies itself with the information from ComboTextTypes.
So far there exist 14 ComboTextTypes in the database, and that number is growing. I simply didn't want to have 14 or more tables and forms, which basically all do the exact same thing. Instead I just have two tables and forms, although a little more complicated ones.
The above mechanic is all set up and works fine.
Description of the problem:
The users want to be able to modify the 14th ComboTextType from inside the combobox. The detour through CoreData is three clicks too many, they know that ComboBoxes can offer an edit button for their value list, and want to use it at that point.
Access offers the "List Items Edit Form" for this purpose. When I enter the EditComboTexts form there, it's working in principle, but (of course) the filter is wrong.
How can I set a filter for that form?
You can filter the rowsource using SQL and simply change the rowsource value of the combo box
Me.Combo0.RowSource = "SELECT myfield FROM Table2 WHERE Table2.myfilter = 'value' ; "
If there are multiple matching elements, which element does the yahoo pipes "unique" module return? Is it the first, the last or can it be any?
From the docs:
This module removes items that contain duplicate strings. You select the element to filter on, and Unique removes the duplicates - if the original feed has five items with the same title, you can configure Unique so only one of these items is included in the output feed.
It would seem unspecified. However, after a couple of tests, it seems to me that the first item is selected. So you should be able to get the right items selected by using a Sort operator before Unique.
To illustrate this, I created 2 example pipes. In both pipes there are 3 input items with attributes:
author=jack title=Bazaar
author=jack title=Git
author=jack title=Arch
In the first pipe, using the Unique operator selects the first item. If you delete the first item, it selects the second.
In the second pipe, I used the Sort operator to order the items by title before piping to Unique. This way Arch is selected. If you delete it, then Bazaar is selected, and so on.
When more than one value of a multiselect is used as a filter on a catalog or catalogsearch page in Magento, the multiple values are or'd together - i.e. the result is the union of the products that have any of these attributes.
How would I get the intersection of the sets of products with the selected attributes - i.e. only those products that have all of the selected attributes?
In the standard behavior of Magento you can only filter for one value like Lucasmus already indicated.
So you seem to be using some customization or module which edits the behavior of the core/Mage/Catalog/Model/Layer/Filter/Attribute.php model.
Also the class Mage_Catalog_Model_Resource_Eav_Mysql4_Layer_Filter_Attribute has to be rewritten, this is exactly the class where you could change the behavior you asked for.
In that class, the method
applyFilterToCollection($filter,$value)
creates the corresponding SQL code to do the filtering.
Currently your module or extension probably uses an OR notation, or uses something like
$connection->quoteInto("{$tableAlias}.value IN (?)", $value),
so it searches for any of your to be filtered values.
To achieve an AND, you will have to rewrite this method by splitting the $value into its distinct parts and using a where clause for each of the individual values.
Hope that makes sense.
Let's consider a multiple selection parameter on a report: Employee
This parameter has a lot of possible values. Initially nothing is shown on the list and there is a textfield search parameter associated, that updates the Employee selection list with top n matches for the searched string.
If the entered search query is John Doe we can imagine that now the selection list shows:
John Doe
...
Xavier John Doesson
Now I can select as many items as I want from this filtered list, but if I want to select both John Doe and Alicia Keys happens the following:
First when I enter the search string "John Doe" the selection list gets populated accordingly
I select John Doe - OK
I enter search string "Alicia Keys", the selection list gets populated also
Selection of John Doe is gone - I want to be able to select both Alicia and John at the same time, but I don't want to go through a thousands of names long selection list
Update:
Forgot to mention that we have an OLAP cube in the background with dimension 'Employee'. This dimension is used as the source of the parameter and the param dataset uses MDX to fetch the values, therefore the SQL solution cannot be applied here.
The current solution creates an custom set with MDX Filter and Head functions and then this set is used in the ROWS-part of the MDX query.
Here is how the set created:
SET setEmployees AS {
HEAD(
FILTER( [Employees].[Employees].ALLMEMBERS,
INSTR([Employees].[Employees].CURRENTMEMBER.Name,#EmployeeSearch,1 >= 1 )
)
,100)
}
Basically the problem with this solution is that how do you add multiple search strings to the instr function
Is there a common solution to this kind of situation? Am I approaching the problem from wrong direction?
What you could do is make the search parameter more flexible, so you can handle input such as:
John OR Jane
If "OR" queries are more common than "AND" queries you could support it with queries such as:
John Jane
Note that this may throw people off, because the search features they're used to (such as Google search) typically tend interpret multiple words in the "AND" sense.
Anyhow, the tricky bit of course is the SQL behind the Employee data set. This should use the search parameter in a more flexible way. You haven't specified how that's currently working, but I imagine you may be using something like:
WHERE Employee.FullName LIKE '%' + #SearchParameter + '%'
You would need to extend that to support "OR" queries. There's a whole range of solutions for that, from quick 'n dirty handmade SQL (e.g. string split combined with WHERE...IN) to full-text querying. Choose a solution that's best for your situation.
If you have a fixed number of search terms than you can do something like the following.
FILTER( [Employees].[Employees].ALLMEMBERS,
INSTR([Employees].[Employees].CURRENTMEMBER.Name,#EmployeeSearch1,1 >= 1) OR
INSTR([Employees].[Employees].CURRENTMEMBER.Name,#EmployeeSearch2,1 >= 1)
)
Even if you can do that, I do not recommend it. You don't have the luxury to index Analysis Services like you do SQL. A better possible approach would be to query your data warehouse for the employees and return the appropriate keys, and then filter by those keys in your MDX statement.
