Firstable , The Default Admin Flag is ADMIN_CVAR.
You Can Change it Easily at #define FLAGS.
if the cvar is 0, the mod won't work, else, it will by send to chat the command

PHP Code:

#include <amxmodx>
#include <colorchat>

#define FLAGS ADMIN_CVAR

new bool:BlockChat;
new eCvar;

public plugin_init()
{
    register_plugin("Block Chat", "V2.0", "Enkore & ImNativus") 
    register_clcmd("say", "HandleSay");
    register_clcmd("say_team", "HandleSay");
    eCvar = register_cvar("chatblock_command", "1")
    register_clcmd("say /chat", "CmdBlockChat");
}

public CmdBlockChat( client, id )
{
    if ( !(get_user_flags( client ) & FLAGS ) && !get_pcvar_num( eCvar ) )
    {
        ColorChat(id, BLUE, "You Are Not An Administrator With ^1%s ^3Levels \ Cvar Is Off.", FLAGS)
        return PLUGIN_HANDLED;
    }
    BlockChat = !BlockChat; 
    new szName[33];
    get_user_name(id, szName, sizeof szName - 1)
    ColorChat( client, BLUE, "The Administrator ^4[ %s ]^3 Has ^4%s ^3The ^4Chat", szName, BlockChat ? "Close" : "Open" );
    return PLUGIN_HANDLED;

i didn't know that.
but this mod is more specificst to show the users that the chat is colsed for an announcment.
btw, the command is blocking the chat also for admins i guess.

Actually just hud_saytext (it toggles on and off regard of the arguments you type after)

This plugin turns off chat for all players, not just for yourself, so hud_saytext command is not comparable to this.
