I would put a button after a message in a WizardScene with a "Cancel" Button. But i retrieve some error:
This is my wizard scene:
const superWizard = new WizardScene('super-wizard',
async ctx => {
ctx.wizard.state.data = {};
ctx.telegram.sendMessage(ctx.from.id, "Insert name", {
parse_mode: 'MarkdownV2',
reply_markup: cancelOrder()
})
return ctx.wizard.next();
},
ctx => {
ctx.wizard.state.data.name = ctx.message.text;
ctx.reply("here is your name: "+ctx.wizard.state.data.name);
return ctx.scene.leave();
}
);
const stage = new Stage([superWizard]);
bot.use(session());
bot.use(stage.middleware());
Here is my cancel order function:
function cancelOrder() {
const annullaBtn = Markup.inlineKeyboard([
Markup.callbackButton('CANCEL', `cancelOrder_btn`),
])
return annullaBtn;
}
and the button action:
bot.action("cancelOrder_btn", (ctx) => {
ctx.replyWithMarkdown(`Ordine *ANNULLATO* correttamente`)
return ctx.scene.leave('super-wizard');
});
The program writes correctly the text, and puts the button. But if i press "CANCEL" it gives error at:
ctx.wizard.state.data.name = ctx.message.text;
as "text is undefined" because i press cancel and i didn't write anything.
So how can i leave the scene without going forward, but if i write a text it goes forward in the wizardScene?
Thank you
Replace
ctx.message.text;
with
ctx.update.callback_query.data;
as there is no message returned by callback button
