Is it possible to send a file to telegram through the site form?

Question

PHP

There was an idea to send files from the site's feedback form to the telegram bot. There is a text sending script, is it possible to implement sending files to telegrams? and how, in php I'm not strong.

<?php



$email = $_POST['user_email'];
$message = $_POST['text'];
$txt = "";
$token = "XXXXXXXXXXXXXXXXXXXXXXX";
$chat_id = "XXXXXXX";
$arr = array(
  'Email' => $email,
  'Сообщение' => $message,

);

foreach($arr as $key => $value) {
  $txt .= "<b>".$key."</b> ".$value."%0A";
};

$sendToTelegram = fopen("https://api.telegram.org/bot{$token}/sendMessage?chat_id={$chat_id}&parse_mode=html&text={$txt}","r");

if ($sendToTelegram) {
  header('Location: thank-you.html');
} else {
  echo "Error";
}
?>

Answer 1

Yes, you can. Use the sendDocument method from bot api. Everything is similar to how you use sendMessage now .
https://core.telegram.org/bots/api#senddocument
https://core.telegram.org/bots/api#inputfile
https://core.telegram.org/bots/api#sending-files
Upload limit files via bot -api -

Answer 2

What does " send {...} to telegram bot " mean? What is this bot, where is it running (on the same machine as the site; or somewhere else on a machine accessible via the network)?
In general, a file can be converted to text (conversion methods - Base64, UUEncode). The data sent to the bot can be formatted in such a way that it can understand where everything is (for example, MIME). The methods mentioned in the answer are used in email and HTTP.
