I recieve text message but photo not. I don't know how to send photo with "sendPoto" method.

Answer 1

You should save the image in your Server and then pass a direct downlaod link to telegram. like this:

//TODO save uploded photo on myfiles/avatar1.png

// send to telegram
file_get_contents("https://api.telegram.org/bot****/sendPhoto?chat_id=1245763214&photo=http://example.com/myfiles/avatar1.png");

Note: When sending by URL the target file must have the correct MIME type (eg, audio/mpeg for sendAudio, etc.).

Answer 2

First of all you must store the file uploaded.

in your html code you have error. you must add enctype='multipart/form-data' to support file input .

So your html code must be like this:

<form action="process.php" method="post" enctype="multipart/form-data">
    <input type="text" name="name">
    <input type="file" name="photo">
    <input type="submit" value="Submit">
</form>

In your php file you must first save file uploaded.

define ('url',"https://api.telegram.org/bot****/");

$info = pathinfo($_FILES['photo']['name']);
$ext = $info['extension']; // get the extension of the file
$newname = "newname.".$ext;

$target = 'images/'.$newname; // the path you want to upload your file
move_uploaded_file( $_FILES['photo']['tmp_name'], $target);

After that you can send this file to telegram api.

$chat_id = '123456'; // telegram user id
$url = url."sendPhoto?chat_id=$chat_id";

$params = [
    'chat_id'=>$chat_id,
    'photo'=>'Your site address/'.$target,
    'caption'=>$_POST['name'],
];

$ch = curl_init();
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/x-www-form-urlencoded'));
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($params));
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$server_output = curl_exec($ch);
curl_close($ch);

echo $server_output;
