navigate on images of a product in a telegram bot - php

Question

I'm working on a telegram bot shop via https://github.com/php-telegram-bot/core in laravel.
In this app , each Product has many images that path of them is stored on th DB.
Now I want when send details of a product , images of that shown one by one that user can navigate them via a prev and next inline keyboard. like this picture :
For that after show all products in the shop as a inline query and after use choose one of them , On Chosen inline result Command, I get a product Id and fetch first image of that from DB like this :
class ChoseninlineresultCommand extends SystemCommand
{
public function execute ()
{
$chosenInlineResult = $this->getChosenInlineResult();
$chosenInlineResultId = $product_id = $chosenInlineResult->getResultId();
$chat_id = $chosenInlineResult->getFrom()->getId();
$product = Product::findOrFail($product_id);
$picture = $product->images->first();
$keyboard = KeyboardController::showProductKeyboard($product_id, $chat_id);
$result = view('show-product', compact('product','picture'))->render();
Request::sendMessage([
'chat_id' => $chat_id,
'text' => $result,
'reply_markup' => $keyboard,
'parse_mode' => 'HTML'
]);
}
}
Also showProductKeyboard of KeyboardController is like this :
static public function showProductKeyboard ($product_id, $user_id)
{
$inlineKeyboard = new InlineKeyboard([]);
$inlineKeyboard->addRow(new InlineKeyboardButton([
'text' => ' previous picture ⬅️️',
'callback_data' => 'prev_pic'
]), new InlineKeyboardButton([
'text' => '➡️ next picture ',
'callback_data' => 'next_pic'
]));
return $inlineKeyboard;
}
And finally show-product blade is simple as :
🛍️ <b>{{$product->title}}</b>
✅ <b>{{str_limit(strip_tags($product->desc), 50)}}</b>
💵 <b>{{number_format($product->price)}}</b> dollor
Picture
Problem is that I do not know how can I implement what I want .

Answer 1

You can't change the product image by callback query, you can change only the text by method editMessageText https://core.telegram.org/bots/api#editmessagetext
The solution can be deleting the message and send a new message with next picture.
And you should set more data in callback_data. For example showproduct_<id next product>
