Hello!

The is too much complex for me to create DIALOG_ID for each dialog in my mode. So I have wrapped Showplayedialog with some trick.

The main idea is that player can't view more than 1 dialog at the same time.
Just want to share. Comments are welcome:

prerequisite: isnull function should be added for future check if input is null:

PHP Code:

#if !defined isnull
    #define isnull(%1) ((!(%1[0])) || (((%1[0]) == '\1') && (!(%1[1]))))
#endif 


First declare fxShowPlayerDialog

PHP Code:

new PlayerDialogFunc[MAX_PLAYERS][90];
new PlayerDialogStyle[MAX_PLAYERS];
fxShowPlayerDialog(playerid, callback[], dialogStyle, header[], text[], button1[], button2[]) {
    new fxCallback[32];
    format(fxCallback, sizeof(fxCallback), "%s", callback);
    PlayerDialogFunc[playerid] = fxCallback;
    PlayerDialogStyle[playerid] = dialogStyle;
    ShowPlayerDialog(playerid, playerid, dialogStyle, header, text, button1, button2);
} 


Next implement OnDialogResponse

PHP Code:

public OnDialogResponse(playerid, dialogid, response, listitem, inputtext[]) {
    switch (PlayerDialogStyle[playerid]) {
        case DIALOG_STYLE_MSGBOX: {
            return CallLocalFunction(PlayerDialogFunc[playerid], "ii", playerid, response);
        }
        case DIALOG_STYLE_INPUT, DIALOG_STYLE_PASSWORD: {
            new formatedInput[256];
            format(formatedInput, sizeof(formatedInput), "%s", inputtext);
            if (isnull(formatedInput)) {
                printf("FormattedInput is null: |%s|", formatedInput);
                return CallLocalFunction(PlayerDialogFunc[playerid], "iis", playerid, response, "\1");
            }
            printf("Input: |%s|", formatedInput);
            return CallLocalFunction(PlayerDialogFunc[playerid], "iis", playerid, response, formatedInput);
        }
        default: {
            return CallLocalFunction(PlayerDialogFunc[playerid], "iii", playerid, response, listitem);
        }
    }
    return 0;
} 


After that in some part of your code you may use fxShowPlayerDialog

PHP Code:

...
fxShowPlayerDialog(playerid, "onDialog", DIALOG_STYLE_MSGBOX, "Dialog title", "Dialog text", "Yes", "No");
...
forward onDialog(playerid, response);
public onDialog(playerid, response) {
// your callback is here
} 


Example with input dialog:

PHP Code:

...
fxShowPlayerDialog(playerid, "onInputDialog", DIALOG_STYLE_INPUT, "Title", "Text", "Yes", "No");
...
forward onInputDialog(playerid, response, inputtext[]);
public onInputDialog(playerid, response, inputtext[]) {
    if (isnull(inputtext)) {
// if input is null
        } else {
// if normal input
        }
} 


So you don't need to create DIALOG_ID for each dialog. You don't need to add code into OnDialogResponse too.
Just call dialog and implement callback.
BTW:
For different styles of dialog you should implement different type of callbacks.
Hope it helps somebody.

P.S. I wish it will be done natively

PHP Code:

#endif
new PlayerDialogFunc[MAX_PLAYERS][90];
new PlayerDialogStyle[MAX_PLAYERS];
fxShowPlayerDialog(playerid, callback[], dialogStyle, header[], text[], button1[], button2[]) {
    new fxCallback[32];
    format(fxCallback, sizeof(fxCallback), "%s", callback);
    PlayerDialogFunc[playerid] = fxCallback;
    PlayerDialogStyle[playerid] = dialogStyle;
    ShowPlayerDialog(playerid, playerid, dialogStyle, header, text, button1, button2);
    return 0;
}
public OnDialogResponse(playerid, dialogid, response, listitem, inputtext[]) {
    switch (PlayerDialogStyle[playerid]) {
        case DIALOG_STYLE_MSGBOX: {
            return CallLocalFunction(PlayerDialogFunc[playerid], "ii", playerid, response);
        }
        case DIALOG_STYLE_INPUT, DIALOG_STYLE_PASSWORD: {
            new formatedInput[256];
            format(formatedInput, sizeof(formatedInput), "%s", inputtext);
            if (isnull(formatedInput)) {
                return CallLocalFunction(PlayerDialogFunc[playerid], "iis", playerid, response, "\1");
            }
            return CallLocalFunction(PlayerDialogFunc[playerid], "iis", playerid, response, formatedInput);
        }
        default: {
            return CallLocalFunction(PlayerDialogFunc[playerid], "iii", playerid, response, listitem);
        }
    }
    return 0;
}

EasyDialog by Emmet_ does the same thing, is more optimised and can do some useful tricks.
