ellchr3 Posted April 9, 2013 Share Posted April 9, 2013 I'm looking to have my query results displayed with an option to "Edit". Once the user clicks "Edit" it will take them to a page with text boxes for each field and allow them to edit(update) the data. Is it better to create a session, query the database for each page, use the GET or POST option, or a combination of any? Or are my thoughts just ridiculous and there's a better way to do what I'm wanting to do?

mac_gyver Posted April 9, 2013 Share Posted April 9, 2013 if your question concerns retrieving the actual data that is being edited, it is best to query the database in case someone else has made changes to the same record. you will get the newest values and/or find that the recored is locked by someone else making changes to it at the same time you are trying to.

jcbones Posted April 9, 2013 Share Posted April 9, 2013 Sort of this idea: <?php session_start(); // ******** EDIT CONNECTION INFORMATION BELOW ************ $hostname = "localhost"; $database = "login"; $username = "root"; $password = ""; // *********** END EDIT CONNECTION INFORMATION ************ $db = new mysqli($hostname,$username,$password,$database); if($_SERVER['REQUEST_METHOD'] == 'POST') { $sql = $db->prepare("UPDATE `users` SET `forename` = ?,`surname` = ?,`email` = ? WHERE `users`.`userid` = ? LIMIT 1"); $forename = $_POST['forename']; $surname = $_POST['surname']; $email = $_POST['email']; $id = $_POST['id']; $sql->bind_param('sssi',$forename,$surname,$email,$id); if(!$sql->execute()) { trigger_error('UPDATE STATEMENT ERROR: ' . $sql->error,E_USER_WARNING); } } if (isset($_SESSION["username"])) { $user_query = $db->prepare('SELECT userid, forename, surname, email FROM users WHERE username = ? LIMIT 1'); $username = $_SESSION['username']; $user_query->bind_param('s',$username); $user_query->bind_result($userid,$forename,$surname,$email); if(!$user_query->execute()) { trigger_error('SELECT STATEMENT ERROR: ' . $sql->error,E_USER_WARNING); } $user_query->fetch(); } else { die("You must be logged in <a href='index.php'>Back</a>"); } <html> <?php include "overallheader.php" ?> <div id ='container'> <div id ='content'> <div id='navBar'> <?php include "navbar.php"?> </div> <div id='userinfo'> </div> <div id ="eventform"> <form name='myForm' action ='edit.php' onsubmit='return validateForm()' method='POST'> <input type='hidden' name='id' value='<?php echo $userid; ?>' /> <table> <tr><td ><input type='text' name='forename' value='<?php echo "$forename"; ?>' /> </td> </tr> <tr><td ><input type='text' name='surname' value='<?php echo "$surname"; ?>' /> </td> </tr> <tr><td ><input type='text' name='email' value='<?php echo "$email"; ?>' /> </td> </tr> <td> <INPUT TYPE="submit" VALUE="Edit"></td> </table> </form> </div> </div> </div> </html> Quote Link to comment https://forums.phpfreaks.com/topic/276713-_session-or-continue-passing-variables-with-get-or-post/#findComment-1423814 Share on other sites More sharing options...
