在redbean中的r :: find是否支持多个搜索字段

Question

I am trying to search by more than one criteria. I have searched Redbean's site for the correct syntax but all they offer is examples using only one search criteria.

$match = R::find('tuba', ' displayType = ? ', [ '$displayType' ]);

I am trying to also search by inventoryNUM. Ive tried executing this code but to no avail.

$match = R::find('tuba', ' displayType = ? , inventoryNUM = ? ', [ '$displayType' , '$inventoryNUM' ]);

Is this the correct syntax? Does R::find even support more than one search criteria?

Answer 1

You can achieve this with the following: $match = R::find( 'tuba', ' displayType = ? AND inventoryNUM = ? ', [$displayType, $inventory]);

Just remember that everything in the 2nd parameter is SQL query to find the desired bean, starting right after WHERE clause. Also you can either use the question mark notation or the slot-notation (:keyname).

The following query is equivalent to the one above: $match = R::find( 'tuba', ' displayType = :displayType AND inventoryNUM = :inventoryNUM ', [':displayType' => $displayType, '':inventoryNUM' => $inventory]);
