Core: Adding one row with two button in inlinekeyboard

[Daniyal-Javani]

Hi
This code add a row with one key:

$inlineKeyboard = new InlineKeyboard([]);
        foreach ($categories as $cat) {
            $inlineKeyboard->addRow(new InlineKeyboardButton([
                'text'          => $cat['name'],
                'callback_data' => $cat['id'],
            ]));
        }

But how can I add one row with two keys?
I tried:

for ($i=0; $i < count($categories); $i++) { 
            $inlineKeyboard->addRow(new InlineKeyboardButton(
                    [
                        'text'          => $categories[$i]['name'],
                        'callback_data' => $categories[$i]['id'],
                    ], [
                        'text'          => $categories[$i+1]['name'],
                        'callback_data' => $categories[$i+1]['id'],
                    ]
            ));
        }

AND

for ($i=0; $i < count($categories); $i++) { 
            $inlineKeyboard->addRow(new InlineKeyboardButton(
                [
                    [
                        'text'          => $categories[$i]['name'],
                        'callback_data' => $categories[$i]['id'],
                    ], [
                        'text'          => $categories[$i+1]['name'],
                        'callback_data' => $categories[$i+1]['id'],
                    ]
                ]
            ));
        }

AND
for ($i=0; $i < count($categories); $i++) { $inlineKeyboard->addRow(new InlineKeyboardButton( [ 'text' => $categories[$i]['name'], 'callback_data' => $categories[$i]['id'], ] ), new InlineKeyboardButton( [ 'text' => $categories[$i+1]['name'], 'callback_data' => $categories[$i+1]['id'], ] )); }
But none of them works. Any help?

```php
$kb = new InlineKeyboard(
[ // row #1
['text'=>'r1b1', 'callback_data' => 'r1b1'], // row #1, button #1
['text'=>'r1b2', 'callback_data' => 'r1b2'] // row #1, button #2
],
[ // row #2
['text'=>'r2b1', 'callback_data' => 'r2b1'], // row #2, button #1
]
);

Thanks but, I want to know how can I do that in a loop like the first code. Suddenly right now I found the solution!

for ($i=0; $i < count($categories) - 1; $i+=2) { 
            $inlineKeyboard->addRow(new InlineKeyboardButton(
                [
                    'text'          => $categories[$i]['name'],
                    'callback_data' => $categories[$i]['id'],
                ]
            ),
            new InlineKeyboardButton(
                [
                    'text'          => $categories[$i+1]['name'],
                    'callback_data' => $categories[$i+1]['id'],
                ]
            ));
        }

Actually I just miss the minus one!

@Daniyal-Javani Hi! Thanks for your answer. But, I have a similar problem.
My categories displaying from database, and can be dynamically added.

If here are 4 rows in table, my inline keyboard looks like this:
[Button, Button] [Button, Button]

But! If I have 5 rows, buttons look the same as written above. Last row not display.
And I need that:
[Button, Button] [Button, Button] [Button]

I tried to use this:

for ($i=0; $i < count($cats) - 1; $i+=2) {
    if ($i % 2 == 0) {
        $keyboard->addRow(new InlineKeyboardButton([
                    'text' => $cats[$i]['name'],
                    'callback_data' => $cats[$i]['id'],
                ]),
        new InlineKeyboardButton([
                    'text' => $cats[$i + 1]['name'],
                    'callback_data' => $cats[$i + 1]['id'],
                ])
        );
    } else {
            $keyboard->addRow(new InlineKeyboardButton([
                    'text' => $cats[$i]['name'],
                    'callback_data' => $cars[$i]['id'],
            ]));
    }
}

Thanks in advance!

@MyZik There is a much nicer solution for this, which is totally dynamic and has no code duplication! (It requires at least PHP 5.6 though)

$items = array_map(function ($cat) {
    return [
        'text'          => $cat['name'],
        'callback_data' => $cat['id'],
    ];
}, $cats);

$max_per_row  = 2; // or however many you want!
$per_row      = sqrt(count($items));
$rows         = array_chunk($items, $per_row === floor($per_row) ? $per_row : $max_per_row);
$reply_markup = new InlineKeyboard(...$rows);

[MyZik]

@noplanman thank you a lot!

But I have a little problem:
If I use foreach, i can easily add "Back" link:

$cats = DB::getPdo()->query("...");

...

foreach ($cats as $cat) {
    $keyboard->addRow(new InlineKeyboardButton([
        'text' => $icon . ' ' . $cat['name'] . ' [' . $count . ']',
        'callback_data' => 'cat_' . $product['id']
    ]));

    /**
     * Back navigate link
     */
    if ($cat === end($cats)) {
        $keyboard->addRow(new InlineKeyboardButton([
            'text' => '🔙 Назад',
            'callback_data' => 'category_' . $cat['parent_id']
        ]));
    }
}

And how can I use that in your example?

$items = array_map(function ($cat) {
    return [
        'text'          => $cat['name'],
        'callback_data' => $cat['id'],
    ];
}, $cats);

[noplanman]

Just add it to the keyboard after my code above 👍

...
$reply_markup = new InlineKeyboard(...$rows);
$reply_markup->addRow(new InlineKeyboardButton([
    'text'          => '🔙 Назад',
    'callback_data' => 'category_' . end($cats)['parent_id'],
]));

@noplanmam awww! It's really easy, thank you!

I used foreach after your code 😆

[Daniyal-Javani]

Hello again!
Can you help me to create keyboard for both dynamic row and dynamic column? For example turn this array to a simple keyboard

$keys = [
            ['7', '8', '9', '+'],
            ['4', '5', '6', '-'],
            ['1', '2', '3', '*'],
            [' ', '0', ' ', '/']
        ]

I want that to handle responses using this array, I mean use one array for both keyboard and it's responses.

[noplanman]

Please check the comments above, you will find your answer there :wink:

[Daniyal-Javani]

Tahnks for your attention, but it's not for dynamic column you fix that with $max_per_row = 2; // or however many you want! .
I mean change it to a keyboard

$keys = [
            ['7'],
            ['4', '5', '6', '-'],
            ['1', '2', '3', '*'],
            [' ', '0']
        ]

[noplanman]

How dynamic should it be? If you have an array available, then you obviously already have rows and columns defined.

Can you please elaborate on what you want exactly?

[Daniyal-Javani]

OOPS! Sorry thanks.

        $keys = [
            ['7'],
            ['4', '5', '6', '-'],
            ['1', '2', '3', '*'],
            [' ', '0']
        ];
        $keyboard = new Keyboard(...$keys);

I learn ... from you! And never seen it before in books or tutorials.

[noplanman]

Glad you got it sorted! Enjoy.

Hi, I would create buttons dinamic, but i don't now how do, this is my code and my file is in Conversations.php\OnboardingConversation.php

` public function askForDatabase()
{
$question = Question::create('¿Que te gustaria saber ?')
->fallback('Elije una opcion, y espera por la siguiente pregunta')
->callbackId('Vamos !!')
->addButtons([
Button::create('Precio')->value('precio'),
]);

    return $this->ask($question, function (Answer $answer) {
        if ($answer->isInteractiveMessageReply()) {
         } else {
                $this->say(Inspiring::quote());
            }
        }
    });
  }

`

[noplanman]

@04211708AC I think you are asking in the wrong project. Are you using this library?

Also, in future it's better to create a new issue instead of commenting on an old closed one :grin:
