How to enable debug mode?

If you are a developer, or just want a more complete “Telegram > Log” enable WP_DEBUG mode.
The plugin debug mode also allows to explore Telegram users and groups as standard posts. This let you to check custom fields for each users and modify them in real time. You’ll notice a new column (= Telegram id for the user) in Subscribers and Groups page.
We don’t suggest to keep WP_DEBUG if not for testing purposes.

How to make dynamic replies? (PHP required)

The best way to integrate PHP code is to build a custom integration plugin, but you can also add PHP to /$commands directly in your WordPress admin dashboard using the Insert Php plugin.

In case you want to scale and choose the first option, you can create a new file called telegram-bot-custom.php and upload it to wp-content/plugins.

The following example, once activated in the plugins list, will reply to /command:

<?php
/*
Plugin Name: Telegram Bot & Channel (Custom)
Description: My Custom Telegram Plugin
Author: My name
Version: 1
*/

add_action('telegram_parse','telegramcustom_parse', 10, 2);

function telegramcustom_parse( $telegram_user_id, $text ) {
    $plugin_post_id = telegram_getid( $telegram_user_id );

    if ( !$plugin_post_id ) {
        return;
    }

    /*
    Here is the dynamic processing and how to reply.
    You can:
    - use if, switch and everything that works in php
    - check if $text is made of multiple words (create an array from $text)
    - customize and code other actions (ex. create WordPress post is $telegram_user_id is your id)
    */

    if ( $text == '/command') {
        telegram_sendmessage( $telegram_user_id, 'Oh, yes you typed /command');
    }

    return;
}

?>

How to set up dynamic keyboards?

You can send custom keyboards directly in php. Every keyboard can be set only when you send a message, and is kept in the client side until another keyboard is sent (in another message). You can also change this behaviour by setting the $one_time_keyboard true or false.

telegram_sendmessage( $telegram_user_id, 'Hello from the other side!'); //Message with no keyboard (or with default one if set in plugin options)
telegram_sendmessage( $telegram_user_id, 'Hello from the other side!', telegram_build_reply_markup( '11,12,13;21,22', true )); //Message with custom keyboard

Here is the details of telegram_build_reply_markup (an array is returned):
telegram_build_reply_markup(
‘11,12,13;21,22’, //The keyboard template (eg. 2 row, 3 columns for the first one and two columns for the second one
true, // $one_time_keyboard (optional) (default false = kept until a new keyboard is sent) (true = kept until the user send something to the bot)
true // $resize_keyboard (optional) (default true)
);

You can also alter keyboards for commands defined in the admin area. Start from the previous custom plugin created, and add the following filter:

add_filter( 'telegram_get_reply_markup_filter', 'telegram_get_reply_markup_filter_custom', 1 );

function telegram_get_reply_markup_filter_custom( $id ) {
    if ( $id ) {
        switch ( $id ) {
            case 7: //Your command ID (found in the url while editing the command)
                telegram_log('####', $id, 'custom keyboard'); //Useful for debug
                return array(
                    'keyboard' => array(array('Top Left', 'Top Right'),array('Bottom')),
                    'resize_keyboard' => true, //true or false (suggested: true)
                    'one_time_keyboard' => true //true or false
                    );            
            default:
                return;
        }
    }
}

How to get user location?

It’s easy, with harvesine algorithm (one-point radius) or standard geolocation (4-points).
These snippets only cover the harvesine algorithm, that is simple and supported by the plugin. To use the standard 4-points geolocation it’s enough to do some php-calc with basic if-then structures.

You can start from the previous custom plugin created, and add the following action:

add_action('telegram_parse_location','telegramcustom_c_parse_location', 10, 3);

function telegramcustom_c_parse_location ( $telegram_user_id, $lat, $long  ) {

  if ( telegram_location_haversine_check ( 45.85, 9.70, $lat, $long, 20 ) ) {
    telegram_sendmessage( $telegram_user_id, 'Inside the radius');
  }

}

The examples sends a “Inside the radius” message when the user is inside the 20-meters radius centered in 45.85 Lat, 9.70 Long.

You have two developer functions to use:

//Check if point is within a distance (max_distance required)
$boolean = telegram_location_haversine_check ( $latitudeFrom, $longitudeFrom, $latitudeTo, $longitudeTo, $max_distance, $min_distance = 0, $earthRadius = 6371000);

//Calculate the distance
$int = telegram_location_haversine_distance ( $latitudeFrom, $longitudeFrom, $latitudeTo, $longitudeTo, $earthRadius = 6371000);

The first function returns a boolean (true/false) depending on given parameters. Please note that $min_distance and $earthRadius are optional.
The second one returns a int (in meters) of the distance. $earthRadius optional.

Both the functions calculates distances on meters. If you want another type of result, just change the $earthRadius.

How to get user photos?

We’ve written simple functions to let developers build everything.
Photos are saved in /wp-content/uploads/telegram-bot/’.$plugin_post_id.’/’.$file_name where $plugin_post_id is the custom post type id associated with the Telegram subscription (ex. ’24’) and $file_name is time().$extension

<?php
/*
Plugin Name: Telegram Bot & Channel (Custom)
Description: My Custom Telegram Plugin
Author: My name
Version: 1
*/

add_action('telegram_parse_photo','telegramcustom_parse_photo', 10, 2);

function telegramcustom_parse_photo ( $telegram_user_id, $photo  ) {

 $plugin_post_id = telegram_getid( $telegram_user_id );

 if ( !$plugin_post_id ) {
  return;
 }

 /*
  Here is the dynamic processing and how to reply.
  You can:
   - use if, switch and everything that works in php
   - check if $text is made of multiple words (create an array from $text)
   - customize and code other actions (ex. create WordPress post is $telegram_user_id is your id)
 */

 /*
   $photo[2]['file_id'] is only one of available sizes. You should make sure that this size exist, or check for another size.
   $photo[1]['file_id'] has lower resolution
 */
 $url = telegram_download_file( $telegram_user_id, $photo[2]['file_id'] ); //Fetch and save photo to your server

 if ( $url ) { //$url is the local url because photo is already saved

  //You can save the entry in your db
  global $wpdb;
  $arr = array( 'telegram_id' => $telegram_user_id, 'plugin_post_id' => $plugin_post_id, 'url' => $url );

  $wpdb->insert(
   $wpdb->prefix . 'your_table_name_that_must_already_exist', $arr, array( '%s' )
  );

  //Or save it as custom field and use it for a Finite State Machine
  update_post_meta( $plugin_post_id, 'telegram_custom_last_photo_received', $url );

  telegram_sendmessage( $telegram_user_id, 'Photo received. Thank you!');
}

?>

Another example, that is a “emergency bot” created for the mid-italy earthquake (24 august 2016) is available on GitHub

Version 3.6 20220927 breaks the entrance to the admin panel

27 de Setembro, 2022 4 replies
As I wrote, version 3.6 20220927 breaks the entrance to the admin panel: Causes an error: "[27-Sep-2022 19:07:27 UTC] PHP Warning: Cannot modify header information - headers already sent by (output started at /home/m/......../........./public_html/wp-content/plugins/telegram-bot/panel/send.php:67) in /home/m/........../........./public_html/wp-includes/pluggable.php on line 1424" Incorrect operation of the php script. The problem was caused by the presence of BOM characters in one or more script files on my site

Nice Plugin, but problems with other plugin

17 de Março, 2022
Nice plugin, easy to use and easy to configure. For someone the functions won't be enough, but for a little Wordpress-Page perfectly good. The bot function with automatic replies is perfect. But I stopped using because of problems with the plugin Einsatzverwaltung. The telegram message was posted two times all the time.

The plugin does not work in places!

20 de Dezembro, 2021
2+ Star for the fact that the plugin exists and in some places it performs its functions, for which I am grateful to the author since I did not find such a plugin 3- Minus for the fact that the author of the plugin does not help solve problems and is not responsible! The functions that are stated do not work! There are no updates and no support

Great
