Modx ditto call and checkboxes

Question

This is my current ditto call and it works when only west is selected in the template variables (The template variable is a checkbox). I need to get this to work when multiple checkboxes are selected.

[[Ditto? &parents=`5` &depth=`1` &tpl=`map_person` &orderBy=`lastname ASC` &filter=`district,West`]]

Answer 1

The &filter should use field,criteria,mode so if it should only work on those who have West checked you should write this:

&filter=`West,2,1|East,1,1|South,1,1|North,1,1`

So it sais: Select a document that West is checked and East isnt checked and South isnt checked and North isnt checked.

You could also create a snippet that does this and goes through the children of parent=5 and echoes out a commaseparated list with all the children IDs and put them in a &documents parameter. Something like this:

[[Ditto? &documents=`[!FindExclusive? &district=`West` &parentid=`5`!]`]]

In the Snippet-code you could write something like this (only pseudo-code under here):

$children = get all children from $parentid;
$documents = new Array();
foreach $children['id']{
    Get the checkboxes from this child
    Check if only the $district checkbox is checked
    if it is true then fill inn the id in $documents-array
}
echo implode(',',$documents);

This will generate a commaseparated list of documents that only has West checked. And you could use the same snippet for East, North and South.
