  • My form php is not working and I can't figure out where I went wrong

    - by user1081524
    I'm fairly new to all this, but I've created a form, and this is what I've written to send it. I've used "[email protected]" here instead of the real address <?php /* Set e-mail recipient */ $myemail = "[email protected]"; /* Check all form inputs using check_input function */ $names = check_input($_POST['names'], "Please return to our Application Form and enter your and your future spouse's names."); $weddingtype = check_input($_POST['weddingtype'], "Please return to our Application Form and fill in what kind of wedding you will be having."); $religioussect = check_input($_POST['religioussect'], "Please return to our Application Form and tell us about your religion and wedding traditions."); $dateone = check_input($_POST['dateone'], "Please return to our Application Form and give us the date for at least one event."); $eventone = check_input($_POST['eventone'], "Please return to our Application Form and list at least one event."); $locationone = check_input($_POST['locationone'], "Please return to our Application Form and give us the location for at least one event."); $durationone = check_input($_POST['durationone'], "Please return to our Application Form and give us the duration of at least one event."); $typeone = check_input($_POST['typeone'], "Please return to our Application Form and tell us whether you would like video, photo or both for at least one event."); $datetwo = $_POST['datetwo']; $eventtwo = $_POST['eventtwo']; $locationtwo = $_POST['locationtwo']; $durationtwo = $_POST['durationtwo']; $typetwo = $_POST['typetwo']; $datethree = $_POST['datethree']; $eventthree = $_POST['eventthree']; $locationthree = $_POST['locationthree']; $durationthree = $_POST['durationthree']; $typethree = $_POST['typethree']; $datefour = $_POST['datefour']; $eventfour = $_POST['eventfour']; $locationfour = $_POST['locationfour']; $durationfour = $_POST['durationfour']; $typefour = $_POST['typefour']; $guests1 = check_input($_POST['guests1'], "Please return to our Application Form and tell us how many guests will attend at least one event."); $guests2 = $_POST['guests2']; $guests3 = $_POST['guests3']; $guests4 = $_POST['guests4']; $concerns = $_POST['concerns']; if(!isset($_POST['submit'])){ $subject = "Quote Application"; /*Message for the e-mail */ $message = "Hello!

  • Can this PHP function be improved?

    - by jasondavis
    Below is some code I am working on for a navigation menu, if you are on a certain page, it will add a "current" css class to the proper tab. I am curious if there is a better way to do this in PHP because it really seems like a lot of code to do such a simple task? My pages will also have a jquery library already loaded, would it be better to set the tab with jquery instead of PHP? Any tips appreciated <?PHP active_header('page identifier goes here'); //ie; 'home' or 'users.online' function active_header($page_name) { // arrays for header menu selector $header_home = array('home' => true); $header_users = array( 'users.online' => true, 'users.online.male' => true, 'users.online.female' => true, 'users.online.friends' => true, 'users.location' => true, 'users.featured' => true, 'users.new' => true, 'users.browse' => true, 'users.search' => true, 'users.staff' => true ); $header_forum = array('forum' => true); $header_more = array( 'widgets' => true, 'news' => true, 'promote' => true, 'development' => true, 'bookmarks' => true, 'about' => true ); $header_money = array( 'account.money' => true, 'account.store' => true, 'account.lottery' => true, 'users.top.money' => true ); $header_account = array('account' => true); $header_mail = array( 'mail.inbox' => true, 'mail.sentbox' => true, 'mail.trash' => true, 'bulletins.post' => true, 'bulletins.my' => true, 'bulletins' => true ); // set variables if there array value exist if (isset($header_home[$page_name])){ $current_home = 'current'; }else if (isset($header_users[$page_name])){ $current_users = 'current'; }else if (isset($header_forum[$page_name])){ $current_forum = 'current'; }else if (isset($header_more[$page_name])){ $current_more = 'current'; }else if (isset($header_money[$page_name])){ $current_money = 'current'; }else if (isset($header_account[$page_name])){ $current_account = 'current'; }else if (isset($header_mail[$page_name])){ $current_mail = 'current'; } // show the links echo '<li class="' .

  • Padding error when using RSA Encryption in C# and Decryption in Java

    - by Matt Shaver
    Currently I am receiving the following error when using Java to decrypt a Base64 encoded RSA encrypted string that was made in C#: javax.crypto.BadPaddingException: Not PKCS#1 block type 2 or Zero padding The setup process between the exchange from .NET and Java is done by creating a private key in the .NET key store then from the PEM file extracted, created use keytool to create a JKS version with the private key. Java loads the already created JKS and decodes the Base64 string into a byte array and then uses the private key to decrypt. Here is the code that I have in C# that creates the encrypted string: public string Encrypt(string value) { byte[] baIn = null; byte[] baRet = null; string keyContainerName = "test"; CspParameters cp = new CspParameters(); cp.Flags = CspProviderFlags.UseMachineKeyStore; cp.KeyContainerName = keyContainerName; RSACryptoServiceProvider rsa = new RSACryptoServiceProvider(cp); // Convert the input string to a byte array baIn = UnicodeEncoding.Unicode.GetBytes(value); // Encrypt baRet = rsa.Encrypt(baIn, false); // Convert the encrypted byte array to a base64 string return Convert.ToBase64String(baRet); } Here is the code that I have in Java that decrypts the inputted string: public void decrypt(String base64String) { String keyStorePath = "C:\Key.keystore"; String storepass = "1234"; String keypass = "abcd"; byte[] data = Base64.decode(base64String); byte[] cipherData = null; keystore = KeyStore.getInstance("JKS"); keystore.load(new FileInputStream(keyStorePath), storepass.toCharArray()); RSAPrivateKey privateRSAKey = (RSAPrivateKey) keystore.getKey(alias, keypass.toCharArray()); Cipher cipher = Cipher.getInstance("RSA/ECB/PKCS1Padding"); cipher.init(Cipher.DECRYPT_MODE, privateRSAKey); cipherData = cipher.doFinal(data); System.out.println(new String(cipherData)); } Does anyone see a step missing or where the padding or item needs to be changed? I have done hours of reading on this site and others but haven't really found a concrete solution. You're help is vastly appreciated. Thanks. -Matt

So, does someone have a solution in Java for getting the current date's three digit Julian day (not Julian date - I need the day this year)? Thanks! Mark

  • Python readability hints for a Java programmer

    - by Samuel Carrijo
    I'm a java programmer, but now entering the "realm of python" for some stuff for which Python works better. I'm quite sure a good portion of my code would look weird for a Python programmer (e.g. using parenthesis on every if). I know each language has its own conventions and set of "habits". So, from a readability standpoint what are conventions and practices which is "the way to go" in Java, but are not really the "pythonic way" to do stuff?

    I'm using Google Web Toolkit with java and google datastore as database. The entity class has arraylist and on trying to retrieve the data from data base I'm getting the exception: Type 'org.datanucleus.sco.backed.ArrayList' was not included in the set of types which can be serialized by this SerializationPolicy or its Class object could not be loaded.
