Question

I use this script to get the collection of my mongo database: http://datatables.net/development/server-side/php_mongodb

My question is: how to retrieve the rows where foo == 'mystring' only?

Answer 1

As you will notice (on line 29) from the source code in the file the mongo collection has been given the name: $m_collection as such:

$m_collection->find(array('foo' => 'mystring'))

Should work.

If this is not what you are looking for maybe you can be more specific and explain exactly what you are trying to do.

UPDATE

It has come to my attention you might want to instead edit the $searchTermsAll variable to search by this field in a doc. By the looks of it this PHP class links in the same as it would normally for SQL as such you should need to do anyhting special and can just enable filtering on datatables and add the value mystring to the foo field.

However to know if it is the right answer you will need to clarify.

UPDATE 2

A more destructive way of doing this that should keep filtering is to replace line 99 with:

$cursor = $m_collection->find(array_merge($searchTerms, 
    array('foo' => 'mystring')), $fields);

That will always make sure that your condition is added to the search terms but keeps the users own search terms.
