PHP - Update Unique Users
Hi guys. I am working on an update function which edits users of the admin area of my website.
The functions works well to certain extend. I need to make sure that when a user is updated that a repeat username is not used, and display a message that a particular user already exist. I have that functionality in my function, however, this part of the code is not executed and I keep getting the error message: Duplicate entry 'b' for key 'username'. I also need to keep intact any part of the content that's not updated, i.e., password not changed, etc. Here's the code: Code: [Select] function editUser($userUsername, $userPassword, $userEmail, $userRealname, $id){ //select users to see if they exist $query = mysql_query("SELECT * FROM authorized_users WHERE username='$userUsername' ") or die(mysql_error()) ; if (mysql_num_rows($query) >= 1 ) { /* Username already exists */ echo "<p><p><span class='current_admin'>Username already exists</span>"; echo '<p>Please <a href="javascript:history.go(-1)">Go Back</a> and complete the form<br>'; echo '<META HTTP-EQUIV="Refresh" CONTENT="8; URL=users_authorized.php">'; } else { /* Username doesn't exist */ $query = mysql_query("UPDATE authorized_users SET username ='$userUsername', password = '$userPassword', email='$userEmail', realname='$userRealname' ") or die (mysql_error()); echo '<p><p><b> 1 User Added</b>'; echo '<META HTTP-EQUIV="Refresh" CONTENT="4; URL=users_authorized.php">'; } } Thanks in advance for your help. Similar TutorialsI have a mysql table which will store users email addresses (each is unique and is the primary field) and a timestamp. I have added another column called `'unique_code' (varchar(64), utf8_unicode_ci)`. What I would very much appreciate assistance with is; a) Generating a 5 digit alphanumeric code, ie: 5ABH6 b) Check all rows the 'unique_code' column to ensure it is unique, otherwise re-generate and check again c) Insert the uniquely generated 5 digit alphanumeric code into `'unique_code'` column, corresponding to the email address just entered. d) display the code on screen. What code must I put and where? **My current php is as follows:** Code: [Select] require "includes/connect.php"; $msg = ''; if($_POST['email']){ // Requested with AJAX: $ajax = ($_SERVER['HTTP_X_REQUESTED_WITH'] == 'XMLHttpRequest'); try{ if(!filter_input(INPUT_POST,'email',FILTER_VALIDATE_EMAIL)){ throw new Exception('Invalid Email!'); } $mysqli->query("INSERT INTO coming_soon_emails SET email='".$mysqli->real_escape_string($_POST['email'])."'"); if($mysqli->affected_rows != 1){ throw new Exception('You are already on the notification list.'); } if($ajax){ die('{"status":1}'); } $msg = "Thank you!"; } catch (Exception $e){ if($ajax){ die(json_encode(array('error'=>$e->getMessage()))); } $msg = $e->getMessage(); } } I have a form that passes multiple images and I wanted them to have a substring of a md5 encrypted time for generating unique codes so I don't delete or overwrite an older file. I keep the actual images in a folder and the path in mysql. The folder is working perfectly and there are no problems generating unique codes but I have been trying all night and I can't figure out why mysql won't update. I can actually get it to update but then I loose the functionallity of the code and if I don't upload a 4 images and leave one blank, the blank one deletes the previously uploaded field in the table row. Here is the md5 encrypted time for generating unique codes: Code: [Select] $unique = strtolower(substr(md5(time()), 0, 4)); This is how it works with the folder: Code: [Select] $filePath = $uploadDir . $unique . $fileName; This is how I get it to update mysql but then loose functionality: Code: [Select] $values[$i] = $unique . mysql_real_escape_string(basename(trim($_FILES[$fields[$i]]['name']))); Here is the entire code: Code: [Select] <?php require_once('storescripts/connect.php'); mysql_select_db($database_phpimage,$phpimage); $unique = strtolower(substr(md5(time()), 0, 4)); $uploadDir = 'upload/'; if(isset($_POST['upload' . $config])) { foreach ($_FILES as $file) { $fileName = $file['name']; $tmpName = $file['tmp_name']; $fileSize = $file['size']; $fileType = $file['type']; if($fileName==""){ $filePath = 'upload/'; } else{ $filePath = $uploadDir . $unique . $fileName; } $filePath = str_replace(" ", "_", $filePath); $result = move_uploaded_file($tmpName, $filePath); if(!get_magic_quotes_gpc()) { $fileName = addslashes($fileName); $filePath = addslashes($filePath); } $fileinsert[]=$filePath; } } $mid = mysql_real_escape_string(trim($_POST['mid'])); $cat = mysql_real_escape_string(trim($_POST['cat'])); $item = mysql_real_escape_string(trim($_POST['item'])); $price = mysql_real_escape_string(trim($_POST['price'])); $about = mysql_real_escape_string(trim($_POST['about'])); $fields = array(); $values = array(); $updateVals = array(); for($i=1; $i<=4; $i++) { $fields[$i] = 'name'.$i; $values[$i] = mysql_real_escape_string(basename(trim($_FILES[$fields[$i]]['name']))); if($values[$i] != '') { $updateVals[] = "{$fields[$i]} = '{$values[$i]}'"; } } $updateNames = ''; if(count($updateVals)) { $updateNames = ", " . implode(', ', $updateVals); } $update = "INSERT INTO image (mid, cid, item, price, about, name1, name2, name3, name4) VALUES ('$mid', '$cat', '$item', '$price', '$about', '$values[1]', '$values[2]', '$values[3]', '$values[4]') ON DUPLICATE KEY UPDATE cid = '$cat', item = '$item', price = '$price', about = '$about' $updateNames"; $result = mysql_query($update) or die (mysql_error()); $id = mysql_insert_id(); ?> <p style="font-size:35px; font-family:Arial, Helvetica, sans-serif; color:#255E67; margin-left:25px;">Your Item Has Been Uploaded!</p> <script type="text/javascript"> setTimeout('ourRedirect()', 2000) function ourRedirect() { location.href='protator_php.php?mid=<?php echo $id ?>' } </script> Hi all, I'm trying to create a PHP script for user's profile to display the amount of times they've been viewed. I'm looking to have this script increase on a unique view, and it should update the variable in the database. Profiles are accessed by the following link: userprofile.php?userid=X (where X is the ID, e.g. 1, 2, 1001, 345982, etc.). The database variable I'm looking to update is called ProfileViews. I began developing the script, which is as follows: Code: [Select] $_SESSION['Viewed'] = 0; if ($_SESSION['Viewed'] == 0) { $profileViewsQuery = mysql_query("SELECT ProfileViews FROM Users WHERE UserID='????'"); $getProfileViews = mysql_fetch_array($profileViewsQuery); $profileViews = $getProfileViews['ProfileViews']; $profileViews = $profileViews + 1; mysql_query("UPDATE Users SET ProfileViews='$profileViews' WHERE UserID='????'"); $_SESSION['Viewed'] = 1; } However, I'm stumped on a couple things. Could you possibly help me out? 1. How can I get the script to recognize the link accessed's ID? E.g. when a user goes to userprofile.php?userid=1001, how can I get the script to identify the ID to update should be 1001? This is where the "????" would be replaced in the code. 2. On page load, the variable is always going to be $_SESSION['Viewed'] = 0, which isn't going to produce unique hits. Do you have any recommendations how I could achieve unique hits using this method? Thanks very much for reading. Hey guys, Im trying to get a page to update profiles working and have been unsuccessful. Its a basic form with a server.php to process the updates. Server.php $username = mysqli_real_escape_string($db, $_POST['username']); $email = mysqli_real_escape_string($db, $_POST['email']); $password_1 = mysqli_real_escape_string($db, $_POST['password_1']); $password_2 = mysqli_real_escape_string($db, $_POST['password_2']); $location = mysqli_real_escape_string($db, $_POST['location']); $class = mysqli_real_escape_string($db, $_POST['class']); $id = mysqli_real_escape_string($db, $_POST['id']); if (empty($username)) { array_push($errors, "Username is required"); } if (empty($email)) { array_push($errors, "Email is required"); } if (empty($password_1)) { array_push($errors, "Password is required"); } if ($password_1 != $password_2) { array_push($errors, "The two passwords do not match"); } if (count($errors) == 0) { $password = password_hash($password_1, PASSWORD_DEFAULT); $query = "(UPDATE accounts SET password='".$password."', username='".$username."', email='".$email."', role='".$role."', class='".$class."' )"; mysqli_query($db, $query); $_SESSION['username'] = $username; $_SESSION['success'] = "Update Successful for user: " . $username; header('location: index.php'); } } update.php <?php session_start(); if (!isset($_SESSION['loggedin'])) { header('Location: ../login.php'); exit(); } if($_SESSION['class'] == 'user') { // Jump to user page header('Location:../user/home.php'); } ?> <html> <head> <meta name="viewport" content="width=device-width, initial-scale=1" /> <title>New User Registration</title> <link rel="stylesheet" type="text/css" href="../css/style.css"> <link href="../css/navbar.css" rel="stylesheet" type="text/css"> </head> <body> <?php include "../assets/navbar.php" ?> <div class="header"> <h2>Update User Info</h2> </div> <form method="post" action="server.php" class="form2"> <?php include('errors.php'); ?> <?php if (isset($_SESSION['success']) && ! empty($_SESSION['success'])) { echo "<div class='success'>" . htmlentities($_SESSION['success']) .

When I process the update it gives me a success message but the data in the table is not updated at all. Any suggestions on what im doing wrong here? Hello,
Here is my current code:
index.php
<html> <body> <form id="hey" name="hey" method="post" onsubmit="return false"> Name:<input type="text" name="name"> <input type="submit" name="submit" value="click"> </form> <table class="table table-bordered" id="update"> <thead> <th>Name</th> </thead> <tbody> <script type="text/javascript"> $("#hey").submit(function() { $.ajax({ type: 'GET', url: 'response.php', data: { username: $('#name').val()}, success: function (data) { $("#update").prepend(data); }, error: function (xhr, ajaxOptions, thrownError) { alert(thrownError); } }); }); </script> </tbody> </table>response.php <?php $username = $_GET['username']; echo "<tr>"; echo "<td>$username</td>"; echo "</tr>"; ?>This code works fine, it prints out the rows as what the user enters. Now what I want to do is, log all these entries to a mySQL database and also, display these rows over the site. i.e., any user who is online, should be seeing this without having to refresh the page too.. Real time updates in a way. How can I achieve that? Thanks! i wanting users to be able to update there email address and check to see if the new email already exists. if the email is the same as current email ignore the check. i have no errors showing up but if I enter a email already in the db it still accepts the new email instead of bringing the back the error message. Code: [Select] // email enterd from form // $email=$_POST['email']; $queryuser=mysql_query("SELECT * FROM members WHERE inv='$ivn' ") or die (mysql_error()); while($info = mysql_fetch_array( $queryuser )) { $check=$info['email']; // gets current email // } if($check!=$email){ // if check not equal to $email check the new email address already exists// $queryuser=mysql_query("SELECT * FROM members WHERE email='$email' "); //$result=mysql_query($sql); $checkuser=mysql_num_rows($queryuser); if($checkuser != 0) { $error= "0"; header('LOCATION:../pages/myprofile.php?id='.$error.''); } } cheers Hello
I am trying to work out how many regular users I have to my site and how long those users tend to be users..
So, I have a table that logs every time a user visits my site and logs in, it stores the date / time as a unix timestamp and it logs their user id.
I started by getting the id's of any user who logs in more than 5 times in a specified period, but now I want to extend that...
SELECT userID as user, count(userID) as logins FROM login_history where timestamp > UNIX_TIMESTAMP('2014-06-01 00:00:00') and timestamp < UNIX_TIMESTAMP('2014-07-01 00:00:00') group by user having logins > 5; I just discovered that I have a major security flaw with my website. Anyone who logs in to the website can easily access other users information as well as delete and edit other users information just by changing the ID variable in the address bar. I have user ID Session started on these pages but still people can do anything they like with other users information just by editing the address bar. For example if your logged in in the address bar of www.mywebsite.com/delete_mystuff.php?id=5 and change the "5" say to a "9" then you will have access to user#9 information. Every important page that I have has this code: Code: [Select] session_start(); if (!isset($_SESSION['user_id'])) { // Start defining the URL. $url = 'http://' . $_SERVER['HTTP_HOST'] . dirname($_SERVER['PHP_SELF']); // Check for a trailing slash. if ((substr($url, -1) == '/') OR (substr($url, -1) == '\\') ) { $url = substr ($url, 0, -1); // Chop off the slash. } // Add the page. $url .= '/index.php'; ob_end_clean(); // Delete the buffer. header("Location: $url"); exit(); // Quit the script. } else { //Else If Logged In Run The Script if((isset($_GET['id'])) && (is_numeric($_GET['id']))) { $id = (int) $_GET['id']; } elseif ((isset($_POST['id'])) && (is_numeric($_POST['id']))) { $id = (int) $_POST['id']; } else { echo ' No valid ID found, passed in url or form element'; exit(); } What am I doing wrong? Please help if you know how to correct this. Many thanks in advance. Can anyone post a generic update function to update mysql table.

I'm new to PHP and I was able to figure out how to populate data from my database into my text fields. I am trying to add the update information to the same php file; however, I am now receiving errors within the data I was able to populate,
Notice: Undefined variable: stmt in C:\xampp\htdocs\Cust_App\update.php on line 47 and errors with the Update statement
Notice: Undefined variable: stmtupdate in C:\xampp\htdocs\Cust_App\update.php on line 96 I had defined the customerID variable above in the code, but it isn't being captured from here. I tried setting up this query like the one which gathered the data, but I'm off by a little bit. I would like the option to be able to update all fields. Any help is appreciated. I'm trying to learn as I may get asked to update other forms in the future.

Hi Guys, I want my UPDATE function from the code below to only update those fields that are NOT empty - if they are empty on submit then do not update or change any values from that field. I know that sounds odd, but with my file fields, when I submit to change something else at a later date it will overwrite the photo, download1,2 & 3 values and as a result I loose my files from the mysql table. Cheers, S <?php include('config.php'); if (isset($_GET['Ter']) ) { $ter = (int) $_GET['Ter']; if (isset($_POST['submitted'])) { //Photo & Document Upload Upload $timestamp_photo = time(); $timestamp_download1 = time(); $timestamp_download2 = time(); $timestamp_download3 = time(); //This is the directory where the files will be saved //Photos $photo_target = "images/"; $photo_target = $photo_target .$timestamp_photo. basename( $_FILES['photo']['name']); //Documents $download_target = "documents/"; $download_target1 = $download_target .$timestamp_download1. basename( $_FILES['download1']['name']); $download_target2 = $download_target .$timestamp_download2. basename( $_FILES['download2']['name']); $download_target3 = $download_target .$timestamp_download3. basename( $_FILES['download3']['name']); //This gets all the other information from the form $photo = ($_FILES['photo']['name']); $download1 = ($_FILES['download1']['name']); $download2 = ($_FILES['download2']['name']); $download3 = ($_FILES['download3']['name']); //Pause Photo/Document Upload foreach($_POST AS $key => $value) { $_POST[$key] = mysql_real_escape_string($value); } $sql= "UPDATE `ter` SET `Ter` = '{$_POST['Ter']}' , `BranchName` = '{$_POST['BranchName']}' , `BranchAddress` = '{$_POST['BranchAddress']}' , `BranchTel` = '{$_POST['BranchTel']}' , `BranchEmail` = '{$_POST['BranchEmail']}' , `BranchLink` = '{$_POST['BranchLink']}' , `Theme` = '{$_POST['Theme']}' , `LocalInfo` = '{$_POST['LocalInfo']}' , `BranchInfo` = '{$_POST['BranchInfo']}' , `photo` = '$timestamp_photo{$_FILES['photo']['name']}' , `download1` = '$timestamp_download1{$_FILES['download1']['name']}' , `download1name` = '{$_POST['download1name']}' , `download2` = '$timestamp_download2{$_FILES['download2']['name']}' , `download2name` = '{$_POST['download2name']}' , `download3` = '$timestamp_download3{$_FILES['download3']['name']}' , `download3name` = '{$_POST['download3name']}' WHERE `Ter` = '$ter' "; mysql_query($sql) or die(mysql_error()); //Unpause Photo/Document Upload //Writes the photo to the server if(move_uploaded_file($_FILES['photo']['tmp_name'], $photo_target)) { echo "<br />The file ".$timestamp_photo. basename( $_FILES['photo']['name']).

I'll only include the query part of the code since that's what is relevant to my problem. The idea is basically to upload a new picture onto the database if no picture already exists for that member and display the picture on the page. If a picture already exists, then the script replaces the old picture with the new one upon upload. But for whatever reason I don't understand, when I try to replace the old pic, it gets inserted in a new row on the database instead of replacing the old row, and the new pic gets displayed on the web page alongside the old. Code: [Select] $query = "SELECT username FROM images WHERE member_id = '".$_SESSION['id']."' AND image_cartegory = 'main'"; $result = @mysql_query($query); $num = @mysql_num_rows($result); if ($num> 0) { //Update the image $update = mysql_query("UPDATE images SET image = '" . $image['name'] . "' WHERE member_id = '".$_SESSION['id']."' AND image_cartegory = 'main'"); $_SESSION['error'] = "File updated successfully."; //really should be session success message. header("Location: member.php"); exit; } else { // NOTE: This is where a lot of people make mistakes. // We are *not* putting the image into the database; we are putting a reference to the file's location on the server $sql = "insert into images (member_id, image_cartegory, image_date, image) values ('{$_SESSION['id']}', 'main', NOW(), '" . $image['name'] . "')"; $result = mysql_query($sql) or die ("Could not insert data into DB: " . mysql_error()); $_SESSION['error'] = "File uploaded succussfully."; //really should be session success message. header("Location: member.php"); } So can anyone tell me what the problem is? Could the fact that my insert script actually uploads the image onto a folder on my server and only stores the path name in the database have anything to contribute to the mixup? Appreciate your responses in advance. Good morning. I am looking fo some help with an update script to update all rows in a table. This is what I have for a form and all looks well. form.php <?php // run the query and put the results in an array variable called $result $result = mysql_query("SELECT * FROM table ORDER BY 'id', 'title', 'text', 'number'"); print "<form method='post' action='update.php'> <table width='100%' border='0' cellspacing='1' cellpadding='1'><tr> <td align='center'><strong>ID</strong></td> <td align='center'><strong>Title</strong></td> <td align='center'><strong>text</strong></td> <td align='center'><strong>Number</strong></td> </tr>\n"; // start a loop to print all of the courses with their book information // the mysql_fetch_array function puts each record into an array. each time it is called, it moves the array counter up until there are no more records left while ($Update = mysql_fetch_array($result)) { // start displaying the info; the most important part is to make the name an array (notice bookinfo[$i]) print "<td align='center'><p>{$Update['id']}</p></td>\n"; print "<td align='center'><input type='text' name='title' value='{$Update['title']}' /></td>"; print "<td align='center'><input type='text' size='40' name='text' value='{$Update['text']}' /></td>\n"; print "<td align='center'><input type='text' size='40' name='number' value='{$Update['number']}' /></td>\n"; print "</tr>\n"; // add 1 to the count, close the loop, close the form, and the mysql connection } print "<tr> <td colspan='4' align='center'><input type='submit' value='submit' />"; print "</td> </tr> </table> </td> </tr> </form> </table>"; print "</tr>\n"; ?><br /><br /> My question is. How do I update this info into the database with the proper info. ie. Update.php? As the title says I need help with multiple update system.. Can't really get it to work at all >.< Here's some code: $selectt = mysql_query("SELECT * FROM exercises WHERE user='" . $_SESSION["user"] . "' AND exname='" . $_GET["edit"] . "'"); echo '<form method="POST" action="exercises.php?edited">'; echo '<div id="newexx">'; while($raw = mysql_fetch_array($selectt)) { echo '<input type="text" name="up[' . $raw["id"] . ']" value="' . $raw["swe"] . '">'; echo '<input type="text" name="up1[' . $raw["id"] . ']" value="' . $raw["eng"] . '"><br>'; echo '<input type="hidden" name="id[' . $raw["id"] . ']">'; } echo '</div>'; echo '<input type="submit" value="Update Exercise">'; echo '</form>'; if(isset($_GET["edited"])) { $swe = $_POST["up"]; $eng = $_POST["up1"]; $id = $_POST["id"]; foreach($id as $value => $index) { $update = "UPDATE exercises SET swe='".$swe."', eng='".$eng."' WHERE id='".$index."'"; mysql_query($update); } Would be thankful for reply! Hello PHP freaks,

Hi: Not sure if this is where to ask this (maybe it's a mySQL Issue)?? I am working on a zip code locator. The field/column "zip" (which holds the zip codes) is set as a UNIQUE Key in the database. Problem is: I want to allow people to enter a new city if there is one they want to add. The only way I can do this is to remove the UNIQUE Key from the column, or I get an error. Some cities - like Malvern, PA and Frazer, PA - have the same zip code: 19355 This works fine, but the issue that now happens is the zip locator on the frontend will no longer find that zip code. Does anyone know what a solution might be? I can post the zip locator code, and maybe there's a chunk of code I can remove or alter to fix this? Not sure how to address this one. |
