Dear Professional PHP Coders, I really need your help here. I am designing a form for registration (Please find the codes below). There are two errors I want corrected on this form. 1. PostBack data on controls. If a user submits a form, and there are errors on the submitted data, php should postback the user's submitted data on the controls. Instead of clearing them (i.e., setting the value to empty). 2. Display an array of all errors during form submission. Here, if a user has failed to provide necessary data on a selected controls, php should create an array of all controls wherein there are incorrect data, and php should echo the array of such incorrect errors below the form. (pls find the code below). I have tried something, but php is not echoing the assumed errors. No reporting at all. Please kindly help me. <?php //Connect to the database through our include include_once "/dat/connString_local.php"; //include the php file that checks whether a user is logged in or not include_once("toplinks_for_join_form.php"); //load the captcha code from the database $sql = mysql_query("SELECT id, captchacode, status FROM captcha"); while ($result = mysql_fetch_array($sql)) { $id = $result['id']; $captchacode_from_dbase = $result['captchacode']; } // echo $captchacode_from_dbase; // Set error message as blank upon arrival to page $errorMsg = array(); // First we check to see if the form has been submitted if (isset($_POST['username'])){ // Filter the posted variables // GET USER IP ADDRESS AND LOCATION DATA $ip = preg_replace('#[^0-9.]#', '', getenv('REMOTE_ADDR')); $address1 = str_replace("[^A-Z a-z0-9]", "", $_POST['address1']); $address2 = str_replace("[^A-Z a-z0-9]", "", $_POST['address2']); $address = $address1 .", ". $address2 ."

I'm looking for a nice, simple way to handle postbacks and specifically messages to the user when the postback work is done. This is my main three-step "procedure" at the moment: - Form send postback data - postback is handled before any output at the beginning of the sites scripts. - When done, header() forwards the user to the same URL, so the user ends up on the same page, but without the warning of sending post data again if the user refreshes the page. Now, I want to show a message box, like "User data saved" or "An error occured". Any suggestions on how to get the success/error messages to the user (preferably without using GET variables like file.php?success=1)?

i am using gwallet on my site from http://radiumone.com/ one step is to add a callback url that can p[erform We will send the following parameters to your Postback URL every time a user completes an offer or payment:• appId is Application ID of your application on RadiumOne Social• userId is the user ID value you've passed to us on iFrame call• amount is the transaction amount of your virtual currency• hash is MD5 hash you can use to verify the postback, calculated as md5([uSER_ID]+":"+[APP_ID]+":"+[sECRET_KEY]), where "+" is string concatenation and [sECRET_KEY] is the secret key of your application• trackId is the tracking value you passed to us on iFrame callNote: Your reply must be a single character 1 on success or 0 otherwise anyone know how to make a php file do this?
