Possible to use a single string to serve two purposes?
I have been searching all over the internet for a way to use a single string as a key for a hash and then also as a key to retrieve a user from a database.
Here is a screenshot of the issue:
As you can see, I have a string called "Dog". Dog is the key for the hashed password, but also the database name. If I add this code to the code, I can get the dog key from the hash:
User::where("password", "=", Hash::make($password))->where("Dog", $id);
But how do I get the Dog key from the hash as the value for the Dog key?
I know this has something to do with a case like:
User::where("password", "=", Hash::make($password))->where(Dog, $id);
but I can't seem to get it working and I'm not sure if it is even possible.
A:
I'm not entirely sure what you're trying to do. You can't use a string as a field name because it's not a column. And you can't use it as a field name because it's a reserved word.
If you want to search by the value of the Dog column, use a lookup, or array. For example:
User::where("Dog", "=", $id)->first();
or
$user = User::where("Dog", $id)->first();
In the second case, you would need to retrieve the Dog ID from the User record to do the lookup.
If you want to retrieve a single record, you can use pluck:
User::where("Dog", $id)->pluck('Dog')->first();
Note that pluck will retrieve the entire Dog field as a single string, even if you're not interested in that portion of the record.
