Okay.Yes, I'm with you, but you have to talk to TS, because the function is he want not me.
The enable function could also be achieved by an AND gate at each input.
That would eliminate the extra power transistor and its power loss.

Don't know.Are discrete diode normally used as protection diodes (D1-4) or do most people use a bridge rectifier module?
The 2n3904/6 are rated at 0.2A max, so they obviously won't work.solenoid as 4 ohms, which at face value should require 3 amps at 12V
Wow, I never realized how much current those body diodes can handle.As I noted, you shouldn't need D1 through D4 with the MOSFETs (note the direction of their substrate diodes).
Why you think that's better than what has been posted?As title says 'best way to enable', you are missing the action of enable on the upper FETs (yes not matters much in practice, but you want the best way) see L298 block diagram.
Since the power is +12V, when you using the N type for the upper driver and then the Vgs = 12V+3V = 15V, where can you get 15V, please suggest a method?The user is controlling a solenoid, i think it should use N fets for upper too, I think its more safe than to have the gate of a pfet in the flow circuit of a device generating collapsing field spikes.
The collapsing field just tends to keep the current flowing in the solenoid.I think its more safe than to have the gate of a pfet in the flow circuit of a device generating collapsing field spikes.
