Hi buddy! I think what you are trying to do here would be best done using just plain HTML or maybe JQuery depending on the effect that you are trying to achieve.

I sounds as though you just need to add a link in your php, very similar to how you would using HTML really :)

To link dynamically you put a php block as the href like below:

  <a href="<?php echo $link ?>">link</a>

You dont need to do this if you are hard coding the likes however. The above is only appropriate if the links are being generated.

Are you using WordPress or just PHP?

You guessed it right Craig. I'm still new and learning coding skills. I am using PHP. My problem is i am using composer and maybe i am having difficulties to include pages. I set my picture into a clickable link and if i hover above it it shows me the desired destination (page) but if i click on it it gives me the error 404 page not found my code is as below;

Index. php

<?php

require 'vendor/autoload.php'; date_default_timezone_set('Africa/Harare');

use Monolog\Logger; use Monolog\Handler\StreamHandler;

function phpAlert($msg_error) { echo '<script type="text/javascript">alert("' . $msg_error . '")</script>';

}

//$log = new Logger('name'); //$log->pushHandler(new StreamHandler('app.txt', Logger::WARNING)); //$log->addWarning('Foo');

$app = new \Slim\Slim( array( 'view' => new \Slim\Views\Twig() ));

$view = $app->view(); $view->parserOptions = array( 'debug' => true ); $view->parserExtensions = array( new \Slim\Views\TwigExtension(), );

$app->get('/', function() use($app){ $app->render('home.twig'); })->name('home');

$app->get('/Resorts Sites in Afica', function() use($app){ $app->render('Resorts Sites in Afica.twig'); })->name('resorts');

$app->get('/contact', function() use($app){ $app->render('contact.twig'); })->name('contact');

$app->get('/search', function() use($app){ $app->render('search.twig'); })->name('search');

$app->get('/search1', function() use($app){ $app->render('search1.twig');

})->name('search1');

$app->post('/contact', function() use($app){ $name= $app->request->post('name'); $age=$app->request->post('age'); $email=$app->request->post('email'); $expected_date=$app->request->post('expected_date'); $country_to_visit=$app->request->post('country_to_visit'); $reason_for_visit=$app->request->post('reason_for_visit'); $payment_method=$app->request->post('payment_method'); $msg=$app->request->post('msg');

if(!empty($name) && !empty($email) && !empty($msg)) { $cleanName = filter_var($name, FILTER_SANITIZE_STRING); $cleanEmail = filter_var($email, FILTER_SANITIZE_EMAIL); $cleanMsg = filter_var($msg, FILTER_SANITIZE_STRING); } else { phpAlert( "All the fields are needed. Please fill all fields and send again" ); die(); $app->redirect('/contact');

}

$transport = Swift_MailTransport::newInstance('/usr/sbin/sendmail -bs'); $mailer = \Swift_Mailer::newInstance($transport);

$message= \Swift_Message::newInstance(); $message->setSubject('Email From Our Website'); $message->setFrom(array($cleanEmail=>$cleanName)); $message->setTo(array('selesgama@gmail.com')); $message->setBody($cleanMsg);

$result = $mailer->send($message); if($result > 0){

phpAlert(   "Thank you for contacting us. We will get to you soon."   ); 
die();
$app->redirect('/');

} else{ phpAlert( "There was an error sending the message. Try again later." ); die();

} $app->redirect('/contact'); });

$app->run();

    <p></p>
    </div> 
    </div> 
  </li>

  </ul>
  </div>
    {% endblock content %}

I have opened a template folder which i have put all my .twig files including the Resorts in Africa.twig

Hope this will make it easier to see where i am loosing it.

Thanks
