send email and get phone number

Hey can you help me ? ??

I see that telegram bot api doesn’t allow to retrieve phone number, but I can ask to the user to insert it, how can I grab the conversation (from a point to another) and send an email?

I have used this snippet

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;
    }

    if ( get_post_meta( $plugin_post_id, 'telegram_custom_state', true ) == 'tablenumber_wait' ) {
        if ( is_numeric( $text) && $text < 30	 ) { 
            $table = sanitize_text_field( $text );
            update_post_meta( $plugin_post_id, 'telegram_custom_tablenumber', $table );
            delete_post_meta( $plugin_post_id, 'telegram_custom_state' ); //Or set "telegram_custom_state" to something else
            die(); //You can comment this if you want to parse other commands
        } else {
            telegram_sendmessage( $telegram_user_id, 'Numero troppo alto. Per quante persone vuoi prenotare?');
            die(); //You can comment this if you want to parse other commands
        }
    } else if ( !get_post_meta( $plugin_post_id, 'telegram_custom_tablenumber' ) ) {
        telegram_sendmessage( $telegram_user_id, 'Per quante persone vuoi prenotare?');
        update_post_meta( $plugin_post_id, 'telegram_custom_state', 'tablenumber_wait' );
        die(); //You can comment this if you want to parse other commands
    }

    return;
}

to insert how many person book the restaurant table but it works immediately when u add the bot instead I want linked to a command and when your”telegram_custom_tablenumber” is filled is stopped to work, It work again after I delete the custom field in the subscriber page details

I need also to add other 2 question, like insert your phone number and when book the table can you help me?

thanks

I have changed the code in that way:

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;
    }
    
    if ( $text == 'Prenota') {
	
    if ( get_post_meta( $plugin_post_id, 'telegram_custom_state', true ) == 'tablenumber_wait' ) {
        if ( is_numeric( $mytext) && $mytext< 30	 ) { 
            $table = sanitize_text_field( $mytext );
            update_post_meta( $plugin_post_id, 'telegram_custom_tablenumber', $table );
            delete_post_meta( $plugin_post_id, 'telegram_custom_state' ); //Or set "telegram_custom_state" to something else
            die(); //You can comment this if you want to parse other commands
        } else {
            telegram_sendmessage( $telegram_user_id, 'Numero troppo alto. Per quante persone vuoi prenotare?');
            die(); //You can comment this if you want to parse other commands
        }
    } else if ( !get_post_meta( $plugin_post_id, 'telegram_custom_tablenumber' ) ) {
        telegram_sendmessage( $telegram_user_id, 'Per quante persone vuoi prenotare?');
        update_post_meta( $plugin_post_id, 'telegram_custom_state', 'tablenumber_wait' );
        die(); //You can comment this if you want to parse other commands
    }
}
    return;
}

now in the telegram subscriber I have the issue that when I insert the. umber of person when command Prenota is sent I have custom field “telegram_custom_state” set to value “tablenumber_wait” where am I wrong?

how I can add when (date and time) book the table and sent an automatic email to a specified email address?

thanks
