javascript - Using php catch to display errors in stripe -

-

i attempting display errors on page when using stripe card number supposed trigger stripe error number 4000000000000002. error seems appear in console 402, can't seem grasp how output php.

i more used javascript, im not sure how try , catch work, assumption try runs code until error thrown , catch runs. want spit out errors page @ charge point of stripe code.

here code

try {   $customer = stripe_customer::create(array(   'email' => $email,   'card'  => $token,   "description" => $quantity . " copies of economic definition of ore -cut-off grades in theory , practice"));    $charge = stripe_charge::create(array(   "amount" => $total, // amount in cents, again   "currency" => "usd",   'customer' => $customer->id,   "metadata" => array("first name:" => $firstname, "last name:" => $lastname)));   $success = '<div class="alert alert-success">   <strong>success!</strong> payment successful. $' . $customertotal . ', , have ordered ' . $quantity . ' copies </div>';    $to  = $email; // note comma   // subject   $subject = 'economic definition of ore purchase';   // message   $message = '     <html>     <head>       <title>sumary of purchase</title>      </head>      <body>        <table>          <tr>            <td> hi ' . $firstname . '</td>           </tr>           <tr>             <td>              <p>here summary of recent purchase.</p>             </td>           </tr>           <tr>            <td>             <p>your total purchase $'.$customertotal . ' </p>             <p>the number of books have ordered <b>'  . $quantity . '</b> </p></td>          </tr>        </table>       </body>     </html>    ';     // send html mail, content-type header must set    $headers  = 'mime-version: 1.0' . "\r\n";    $headers .= 'content-type: text/html; charset=iso-8859-1' . "\r\n";     // additional headers    $headers .= 'to: '. $firstname .' <' . $email . ' >  ' . "\r\n";    $headers .= 'from: comet <info@cometstrategy.com>' . "\r\n";    // $headers .= 'bcc: birthdaycheck@example.com' . "\r\n";     // mail    mail($to, $subject, $message, $headers); }  catch(\stripe\error\card $e){    $e_json = $e->getjsonbody();    $error = $e_json['error']; } }?> <span class="payment-success">  <?= $success ?>  <?= $error ?> </span>

i have update code based on this question. errors don't display when use error code credit card numbers, not sure doing wrong.

try {   $customer = stripe_customer::create(array(   'email' => $email,   'card'  => $token,   "description" => $quantity . " copies of economic definition of ore -cut-off grades in theory , practice"             ));   $charge = stripe_charge::create(array(   "amount" => $total, // amount in cents, again   "currency" => "usd",   'customer' => $customer->id,   "metadata" => array("first name:" => $firstname, "last name:" => $lastname))    );     $successtest = 1;    $success = '<div class="alert alert-success">    <strong>success!</strong> payment successful. $' .        $customertotal . ', , have ordered ' . $quantity . ' copies </div>';    }     catch(stripe_carderror $e) {      $error1 = $e->getmessage();    } catch (stripe_invalidrequesterror $e) {      // invalid parameters supplied stripe's api      $error2 = $e->getmessage();    } catch (stripe_authenticationerror $e) {      // authentication stripe's api failed      $error3 = $e->getmessage();    } catch (stripe_apiconnectionerror $e) {      // network communication stripe failed      $error4 = $e->getmessage();    } catch (stripe_error $e) {      // display generic error user, , maybe send      // email      $error5 = $e->getmessage();    } catch (exception $e) {      // else happened, unrelated stripe      $error6 = $e->getmessage();    }     if ($successtest!=1)     {    ?>     <span class="payment-success">       <?= $error1 ?>       <?= $error2 ?>       <?= $error3 ?>       <?= $error4 ?>       <?= $error5 ?>       <?= $error6 ?>     </span>   <?php    }   }    ?>      <span class="payment-success">       <?= $success ?>     </span>

you can catch of them, response json well:

catch (exception $e) {     $body = $e->getjsonbody();     $err  = $body['error'];     $errormessage =  $err['message']; }

java - UML - How would you draw a try catch in a sequence diagram? -

is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
