But if you be zombie you type !p90 on the chat or sm_p90 on console the zmarket will updated your primary weapons like if your first pirm weapons is ak47 at zmarket and you type !p90 on chat for example your primary weapons on zmarket load out will got updated can you help me or explain me!!?

That's because those servers are using a modified version of the ZR plugin. They probably had developers who implemented the quick buy feature (using sm_<weaponname> or !<weaponname>) into the plugin.

That plugin that Franc1sco recommended also works but hasn't been written with all the ZMarket features in mind.
That plugin is good for the beginning (it also checks for infected players to prevent exploitation etc. iirc).

But if you really want to have the ZMarket features included (Loadout Save, Auto-Rebuy)
Morell, Server Manager of Mapeadores (?), has a github repository of a modified ZR Plugin that has those features.
