PHP MySQL Dialogflow

Question

I\'m setting up a chatbot (dialogflow) with a PHP webhook

What I want to do is to take the user input to query a MySQL table and pass the result back to the dialogf

Answer 1

whenever the webhook gets triggered you need to listen to actions from JSON responses, from the action made the switch case of actions

index.php

 "RMC",
                "speech" => "I am not able to understand. what do you want ?",
                "displayText" => "I am not able to understand. what do you want ?",
                "contextOut" => array()
            ));
    }
}
function sendMessage($parameters) {
    header('Content-Type: application/json');
    $data = str_replace('\/','/',json_encode($parameters));
    echo $data;
}
$input = json_decode(file_get_contents('php://input'), true);
if (isset($input["result"]["action"])) {
    processMessage($input);
}
?>

get_enews.php

 0){
    $row=pg_fetch_assoc($Result);
    $getNews= "Here is details that you require - Link: " . $row["link"];
        $arr=array(
            "source" => "RMC",
            "speech" => $getNews,
            "displayText" => $getNews,
        );
        sendMessage($arr);
    }else{
        $arr=array(
            "source" => "RMC",
            "speech" => "No year matched in database.",
            "displayText" => "No year matched in database.",
        );
        sendMessage($arr);
    }
}
?>

So when the action gets caught it will get executed and goes in the getNews($param); function here I am getting year as a response from the user in my case and I am executing the query in the database and giving back a response from the database.
