Structured Message TYPE_GENERIC stopped working about fb-messenger-php HOT 15 CLOSED

It appears that null value should be used explicitly as the proper workaround (reason why I am not seeing any issue). If we update the code we need to use @wolzogen cleaner version, so the pull request should be resubmitted with the cleaner/shorter code.

Thanks Jason for replying even on Sunday.

Yes, I cloned the latest code with the folders Menu and Messages along with FbBotApp.php file and update the same in mine.
Was their any particular update sent for Structured message of generic message type ? If so, please it would be great if you can link me to the commit so that I can cross check.

Just tried the following code too, this also fails to work.

  case 'generic':
                    $bot->send(new StructuredMessage($message['sender']['id'],
                        StructuredMessage::TYPE_GENERIC,
                        [
                            'elements' => [
                                new MessageElement("First item", "Item description", "", [
                                    new MessageButton(MessageButton::TYPE_POSTBACK, 'First button'),
                                    new MessageButton(MessageButton::TYPE_WEB, 'Web link', 'http://facebook.com')
                                ]),
                                new MessageElement("Second item", "Item description", "", [
                                    new MessageButton(MessageButton::TYPE_POSTBACK, 'First button'),
                                    new MessageButton(MessageButton::TYPE_POSTBACK, 'Second button')
                                ]),
                                new MessageElement("Third item", "Item description", "", [
                                    new MessageButton(MessageButton::TYPE_POSTBACK, 'First button'),
                                    new MessageButton(MessageButton::TYPE_POSTBACK, 'Second button')
                                ])
                            ]
                        ],
                        [ 
                        	new QuickReplyButton(QuickReplyButton::TYPE_TEXT, 'QR button','PAYLOAD')
                        ]
                    ));
                    break;

P.S : Other functionality are working, hence I am figuring out some code issue with particular 'generic' message type.
Curl error and json_encode were the major update done recently I believe only the FbBotApp.php.

Yes, it was working well before and then it got stopped working all of a sudden.
Basically when the http_build_query issue arose 2 days ago, I tried debugging and fixed the same by using json_encode which then I realised the same has been fixed here, which made be update my pimax lib for any other open issues too.

Since then the Generic template has stopped working and I haven't been able to find any temporary fix too.

Meanwhile tried a core php generic template php code too, it also failed to work.
I am bit confused, how come only Generic template not working.

Sample core php code I tried :

         case 'test':
                       
     $answer = ["attachment"=>[
      "type"=>"template",
      "payload"=>[
        "template_type"=>"generic",
        "elements"=>[
          [
            "title"=>"Welcome to fb bot",
            "item_url"=>"https://www.basezap.com/guide-to-flush-redis-databases-and-keys/",
            "image_url"=>"https://www.basezap.com/wp-content/themes/basezap/images/logo.png",
            "subtitle"=>"We\'ve got the right hat for everyone.",
            "buttons"=>[
              [
                "type"=>"web_url",
                "url"=>"https://google.com",
                "title"=>"View Website"
              ],
              [
                "type"=>"postback",
                "title"=>"Start Chatting",
                "payload"=>"DEVELOPER_DEFINED_PAYLOAD"
              ]              
            ]
          ]
        ]
      ]
    ]];
                            $senderID = $message['sender']['id'];
     $response = [
    'recipient' => [ 'id' =>$senderID  ],
    'message' => $answer 
];


$ch = curl_init('https://graph.facebook.com/v2.6/me/messages?access_token='.Yii::app()->params['token']);    // You need to update your token variable here.
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($response));
curl_setopt($ch, CURLOPT_HTTPHEADER, ['Content-Type: application/json']);
if(!empty($input)){
$result = curl_exec($ch);
}
curl_close($ch);

break;

Can you please try above code, if it works for you ?

from fb-messenger-php.

@pulkit8 what does the $result variable contain?

PS: this piece of code works fine for me

from fb-messenger-php.

The above code works, I forgot to correct this

 
if(!empty($input)){
$result = curl_exec($ch);
}

to
$result = curl_exec($ch);

So, now the issue is only with the the library structured message of type Generic and List

Here is the error

{"error":{"message":"(#100) The parameter name_placeholder[elements][0][default_action][type] is required","type":"OAuthException","code":100,"fbtrace_id":"CI6GGsRsdTy"}}

I have submitted pull request for the fix.

Basically the MessageElement needs a check for non empty default action parameter. From now, facebook doesn't allow the particular parameter to be blank for structured message of type list and generic.

Thank you everyone for the support.

The code needs a fix to support generic and list type of structured message. It fails in absence of call action.

HI,

I have same error too

And

[error] => Array
        (
            [message] => (#100) The parameter name_placeholder[elements][0][default_action][type] is required
            [type] => OAuthException
            [code] => 100
            [fbtrace_id] => CzjZId6Micu
        )

)

from fb-messenger-php.

FInally, Ifound a way for this sequence:

$rsp = $bot->send(new StructuredMessage($senderid, StructuredMessage::TYPE_GENERIC, [
        'elements' => [
            new MessageElement($user->getFirstName().' '.$user->getLastName(), ' ', $user->getPicture())
        ]
    ],
    [
       new QuickReplyButton(QuickReplyButton::TYPE_TEXT, 'QR button','PAYLOAD')
    ]
));

Problem is here:
new MessageElement($user->getFirstName().' '.$user->getLastName(), ' ', $user->getPicture())

construct of it is:
__construct($title, $subtitle, $image_url = '', $buttons = [], $url = '', $default_action = [])

Seems that better is to init default for $default_action = null...

To work, just i add on call null parameter:
new MessageElement($user->getFirstName().' '.$user->getLastName(), ' ', $user->getPicture(), null, null, null)

Yes definitely the cleaner code should be updated. Have created a new pull request with the same.

Applying the patch would surely solve the problem for people referring the example code for development.
