Dynamical array of callback's data for use in `InlineKeyboard`

[NabiKAZ]

I know about InlineKeyboard class, can get each inline keyboard buttons as separated argument.

new InlineKeyboard($keyboard_buttons1, $keyboard_buttons2, ...);

Now I have $menus dynamical array of callback's data.
I want to read all the data with foreach and make category 3 each for every line I create.

Be like this:

Sample code:

$menus = [
	'x1'=>'y1',
	'x2'=>'y2',
	'x3'=>'y3',
	'x4'=>'y4',
	'x5'=>'y5',
	'x6'=>'y6',
	'x7'=>'y7',
];
$keyboard_buttons = [];
$keyboard_buttons_line = [];
$n = 0;
foreach ($menus as $key => $value) {
	$n++;
	$keyboard_buttons_line[] = [
		'text'          => $value,
		'callback_data' => $key,
	];
	if ($n % 3 == 0 || count($menus) == $n) {
		$keyboard_buttons[] = $keyboard_buttons_line;
		$keyboard_buttons_line = [];
	}
}

echo "<pre>";
print_r(new InlineKeyboard($keyboard_buttons[0], $keyboard_buttons[1], $keyboard_buttons[2])); //THIS HAVE BUG !!! (I don't know how many argument must be set.)

I thinks must be use call_user_func_array function or ReflectionClass core class.

I find solution in this: #496 ticket.

Solution 1:

return new InlineKeyboard(...$keyboard_buttons);

Solution 2:

$inline_keyboard = new InlineKeyboard([]);
foreach($keyboard_buttons as $keyboard_button) {
        call_user_func_array([$inline_keyboard, 'addRow'], $keyboard_button);
}
return $inline_keyboard;

And completely simplified:

$inline_keyboard = new InlineKeyboard([]);
$keyboard_buttons = [];
$n = 0;
foreach ($menus as $key => $value) {
	$n++;
	$keyboard_buttons[] = new InlineKeyboardButton([
		'text'          => $value,
		'callback_data' => $key,
	]);
	if ($n % 3 == 0 || count($menus) == $n) {
		call_user_func_array([$inline_keyboard, 'addRow'], $keyboard_buttons);
		$keyboard_buttons = [];
	}
}
return $inline_keyboard;

Nice solution!

I've done something similar to this in the past, here my solution to give you some inspiration 😇

$keyboard_buttons = [];
foreach ($menus as $callback_data => $text) {
    $keyboard_buttons[] = new InlineKeyboardButton([
        'callback_data' => $callback_data,
        'text'          => $text,
    ]);
    // Or if you like 1-liners:
    // $keyboard_buttons[] = new InlineKeyboardButton(compact('callback_data', 'text'));
}

$keyboard_rows        = array_chunk($keyboard_buttons, 3);
$data['reply_markup'] = new InlineKeyboard(...$keyboard_rows);

and just for the sake of it, a tiny version:

array_walk($menus, function (&$text, $callback_data) {
    $text = new InlineKeyboardButton(compact('callback_data', 'text'));
});
$data['reply_markup'] = new InlineKeyboard(...array_chunk($choices, 3));

Note: You'll need at least PHP 5.6 for the argument unpacking to work.

wow that's perfect.
I did not know array_chunk function, this is nice function.
