Ajuda para exibir imagem dentro da janela de share do facebook

Recommended Posts

Olá pessoal, beleza?!! Espero que sim!

Vou tentar explicar bem meu problema para ver se aparece um anjo na minha vida e me ajuda com isso!

 

Tenho um projeto quiz para facebook. Todo o tráfego é gerado pelos próprios usuários que fazem o teste, aparece a foto do usuário e ele compartilha em seu facebook.

 

Porém a taxa de compartilhamento está muito baixa, percebi que não esta exibindo a  imagem certa dentro da janela de share do facebook.

 

Acredito que quem conhece php e/ou javascript consegue ler o código e ver qual código é responsável por puxar a imagem do resultado dentro da janela de share.

 

É exibida a imagem de "capa", mas não a imagem do resultado.

 

Por favor, veja o funcionamento, basta logar com facebook e para iniciar o teste: https://testesdivertidos.com/qual-seu-status-de-relacionamento-para-este-ano/

 

Após aparecer o resultado, clique em COMPARTILHAR, verá que a imagem da capa aparece no share, ao invés da imagem do resultado.

 

Bom, os arquivos responsáveis acredito serem 3.

 

wp-quiz-pro.php

inc/class-fb-quiz.php

inc/class-wp-quiz-pro.php

 

Obs: "class-fb-quiz.php" e "class-wp-quiz-pro.php" estão dentro da pasta inc

 

Segue código, wp-quiz-pro.php:

      Bom dia.
       
      Estou desenvolvendo uma aplicação que vai acessar e gravar dados via webservice dentro do nosso crm... mas estou com um problema que quando tento fazer o acesso mostra a seguinte mensagem de erro:
       
      Fatal error: Uncaught SoapFault exception: [WSDL] SOAP-ERROR: Parsing Schema: can't import schema from 'http://dsksp015.phonoway.com.br:8051/wsDataServer/mex?xsd=xsd0' in /home/httpd/html/phonoweb.com.br/public_html/carrinhobitrix_busca/teste_soap.php:113 Stack trace: #0 /home/httpd/html/phonoweb.com.br/public_html/carrinhobitrix_busca/teste_soap.php(113): SoapClient->SoapClient('http://187.93.2...') #1 {main} thrown in /home/httpd/html/phonoweb.com.br/public_html/carrinhobitrix_busca/teste_soap.php on line 113
       
      Não sei se faz alguma diferença, mas nosso CRM é o TOTVS RM
       
      Grato.

      Boa noite! estou com dúvidas em relação a array, eu tenho uma procedure no SQL Server e essa procedure exibe uma lista de resultados, eu gostaria de pega o valor desses resultados e lista em um array para eu comparar com outro valor que vai ser selecionado em um select , tipo abaixo:
       
      $arraySelect = $db->prepare(exec WebSite.dbo.server_value_product 2);
      $arraySelect->execute();
      $arrayExemple = $arraySelect->fetchAll();

      procedure_list = array($arrayExemple);
       
      !in_array($valorSelect, $procedure_list){
         echo 'O Valor selecionado não existe nos resultados da procedure';
      }
       
       
      alguem sabe como posso listar o resultado da procedure em array. e sabe se o valor que procuro está entre os resultados da array.

      Galera já não sei mais onde procurar, estou configurando o processo de login com certificação digital porém não consigo ler o retorno. No site da Certisign explica em java e .Net mas utilizo em minha aplicação da intranet tudo em PHP como eu teria que fazer. Segue exemplo que eles fornecem em .Net
       
      <form action="https://autenticador.certisign.com.br/CertisignLogin/certificado/login" method="get"> <input type="hidden" value="209" id="id" name="id"> <input type="hidden" value="CHAVE CRIPTOGRAFICA INICIAL" id="nome" name="nome"> <input type="hidden" value="http://www.seusite.com.br/suaAplicacao/retorno" id="retorno" name="retorno"> <div> <input type="image" src="images/ico-certisign_30x30.png" alt="Submit" id="btnLoginCertisign"> </div> </form> O de cima envia até aí tudo bem
       
      Abaixo o retorno que é o que não consigo fazer em PHP
       
      string retorno = Request["cb"]; string encryptionKey = "<conteúdo da chave criptográfica descarregada na etapa 2>"; retorno = CryptoLogin.Instance.DecryptText(retorno,encryptionKey);</conteúdo> A variável retorno deverá mostrar as informações como o exemplo aaixo.
       
      CertificadoBean: { emissor: Certisign Autoridade Certificadora TESTE, nome: "PROPRIETARIO DO CERTIFICADO DE TESTE", cpf: "001.002.003-44", cnpj: "", OAB: "", validade: "2015-05-27 20:59:59", emissao: "2014-05-27 21:00:00", email: "proprietario.teste@certisign.com.br", certificadoBase64: "MIIFmDCCBICgAwI......

      Estou desenvolvendo um site de vinhetas, mas estou com o seguinte problema. Quando o cliente clica em um áudio ele toca normalmente, mas quando clica em um segundo com o primeiro ainda em execução, ficam os dois áudios executando ao mesmo tempo no sit.
      Gostaria que um executasse por vez.
       
      Lembrando que os áudios estão inseridos separadamente.

      Queria saber como fazer esse select e quando eu trazer um estado ele já puxa as cidades contidos nele, e ao escolher a cidade ele trazer os bairros. Consegui pela internet mas só com estados e cidades. no caso em 2 níveis, e eu precisaria em 3, faço pelo mysqli
       
      Em estados no banco está assim
      CREATE TABLE `estados` ( `id_estado` int(10) NOT NULL, `estado` varchar(30) NOT NULL ) ENGINE=Aria DEFAULT CHARSET=latin1; -- -- Extraindo dados da tabela `estados` -- INSERT INTO `estados` (`id_estado`, `estado`) VALUES (1, 'Rio de Janeiro'), (2, 'Minas Gerais'); Cidades
      CREATE TABLE `cidades` ( `id_cidade` int(10) NOT NULL, `id_estado` int(10) NOT NULL, `cidade` varchar(255) NOT NULL ) ENGINE=InnoDB DEFAULT CHARSET=latin1; -- -- Extraindo dados da tabela `cidades` -- INSERT INTO `cidades` (`id_cidade`, `id_estado`, `cidade`) VALUES (1, 1, 'Rio de Janeiro'), (2, 2, 'Belo Horizonte'); E bairros
      CREATE TABLE `bairros` ( `id_bairro` int(10) NOT NULL, `id_cidade` int(10) NOT NULL, `bairro` varchar(255) NOT NULL ) ENGINE=InnoDB DEFAULT CHARSET=latin1; -- -- Extraindo dados da tabela `bairros` -- INSERT INTO `bairros` (`id_bairro`, `id_cidade`, `bairro`) VALUES (1, 1, 'Centro'), (2, 1, 'Tijuca'), (3, 1, 'Leblon'), (4, 2, 'Pampulha');
