PHP - Updating Mysql On Logout
is it possible to update data in mysql when a user clicks logout?
Similar TutorialsI am having problems understanding the reason for why the user has to click logout twice, here's the bulk of the code: <?php ini_set('display_errors',0); require_once 'header.html'; require_once 'db.functions.php'; require_once 'config.php'; $database = dbConnect($host, $username, $password, $database); // should output 1 or nothing at all! if($database == true) { // now connected? // carry on with logic of outputting the blog contents: $result = entries("SELECT * FROM entries"); printf("<table>"); while($row = mysql_fetch_array($result)) { printf(" <tr> <td>%s</td> <td>%s</td> </tr> <tr> <td colspan=\"2\">%s</td> </tr> ", $row[2], $row[4], $row[3]); } printf("</table>"); printf("\n\n"); session_name("jeremysmith_blog"); session_start(); if(array_key_exists('login',$_SESSION)) { if($_SESSION['login'] == 1) // change this to correspond with session on the login.php script { printf("<p>Welcome %s</p> <p>To logout, click <a href=\"index.php?action=logout\">here</a></p> ",$_SESSION['username']); } } else { printf("<p>You are not logged in, please click <a href=\"login.php\">here</a> to login.</p>"); } } else { printf("\n<p id=\"error\">Could not connect to database, please try again later.</p>"); } // init the logout script? if(array_key_exists('action',$_GET)) { if($_GET['action'] == 'logout') { // log user out of the system: unset($_SESSION['login']); unset($_SESSION['username']); session_destroy(); } } printf("\n"); // just for output format! require_once 'footer.html'; Why does the user have to click logout twice, have I missed anything? Any helps appreciated thanks. Hi, Apologies to keep going on about this but I have hit a brick wall over updating my database with XML. I have spent around 100 hours on this and so far I can only copy the file, I am unable so far to update my database with the information from the XML file. I would be very grateful for any help you can offer to fix this. Code: [Select] ----Code so far----> $xmlReader = new XMLReader(); $filename = "datafeed_98057.xml"; $url = "http://www.domain.co.uk/datafeed.xml"; file_put_contents($filename, file_get_contents($url)); $xmlReader->open($filename); while ($xmlReader->read()) { switch ($xmlReader->name) { case'prod': $dom = new DOMDocument(); $domNode = $xmlReader->expand(); $element = $dom->appendChild($domNode); $domString = utf8_encode($dom->saveXML($element)); $prod = new SimpleXMLElement($domString); $id = $prod->prod['id']; $description = $prod->name; $image = $prod->awImage; $fulldescription = $prod->desc; //insert query if(strlen($prod) > 0) { $query = mysql_query("REPLACE INTO productfeed (id, description, fulldescription, image) VALUES ('$id','$description','$image','$fulldescription') "); echo $id . "has been inserted </br>"; } else{echo ("This does not work </br>");} } This is an outline of the XML feed I am using, it only includes one item which I am using as a test: Code: [Select] - <merchant id="1829" name="Pinesolutions.co.uk"> - <prod id="39920873" pre_order="no" web_offer="no" in_stock="yes" hotPick="no" adult="no"> - <text lang="EN"> <name>Oakleigh Wall Mirror 60x90</name> <desc>Mirrors are useful anywhere in the house.

For the last 5 weeks I have been trying to get the following code to work but I am still unable to do it. The code does copy the file from my root folder into another (I eventually plan to use external download onto my server). However, it comes up with the following error: "Cannot instantiate non-existent class: xmlreader in" which refers to this: $xmlReader = new XMLReader(); Does anyone have any experience of transferring data from an XML file to a database? I am using PHP 5 so I dont know why this doesn't work. <?php ini_set('display_errors', 1); error_reporting(-1); $host="hostname"; // $username="username"; // $password="password"; // $db_name="db"; // $tbl_name="productfeed"; // // Connect to server and select database. mysql_connect("$host", "$username", "$password")or ("no connection"); mysql_select_db("$db_name")or die("Database Connection Error"); $xmlReader = new XMLReader(); $filename = "datafeed_98057.xml"; $url = "[url=http://www.ukhomefurniture.co.uk/datafeed.xml]http://www.ukhomefurniture.co.uk/datafeed.xml[/url]"; file_put_contents($filename, file_get_contents($url)); $xmlReader->open($filename); while ($xmlReader->read()) { switch ($xmlReader->name) { case'prod': $dom = new DOMDocument(); $domNode = $xmlReader->expand(); $element = $dom->appendChild($domNode); $domString = utf8_encode($dom->saveXML($element)); $product = new SimpleXMLElement($domString); $product_code = $product->prod['id']; $image = $product->awImage; //insert query if(strlen($product) > 0) { $query = mysql_query("REPLACE INTO productfeed (image) VALUES ('$awImage')"); echo $awImage . "has been inserted </br>"; die('yes it works'); error_reporting(E_ALL); if (ini_get('display_errors')) { ini_set('display_errors', 1); } } break; } } ?> MOD EDIT: DB credentials removed. Hi, when someone logs in to my page, i have a form displayed with names, address, etc...what i need to do is when i hit the update button for that information to go into the MYSQL table I have created and over write that information if a user updates...so how do i do that? Hello, I've been tasked with updating our code base from mysql to something that will work with php 7. It's older code that was written by 2 or 3 individuals before me and it's not at all object oriented. There are about 540 different files that I will end up having to edit to make it all up to date. I'm not a very experienced programmer myself, and I'm in need of some guidance. There are some files that have functions that call and use mysql queries three or four files deep and going through and editing one function leads me to having to update 4 or 5 other files which breaks stuff somewhere else down the road. I was wondering if anyone has some suggestions on ways to make this process less painful. The other thing is that by using PDO in a not OO style, it seems like I'm losing a lot of its benefits. Should I consider using MYSQLi instead of PDO considering the circumstances? Are there any resources that you could point me to in order to help me learn the skills I need to make it through this upgrade? Thanks for the help! Hi All, Whenever I try to update any piece of PHP code to update a MySQL database, nothing happens. I have tried copying in some of the working codes of a website and tried the same, but no success. I recently installed XAMPP. I am connecting using the correct user id and pass to the database. The scripts are not giving me any error, but just not connecting, that's all. While making such a usage as noted below <FORM name="form1" method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>" > I get the following error Firefox can't find the file at /C:/xampp/htdocs/="<?php.. so on Why does this happen? I am pretty new to this, so please do help. Thanks, Satheesh P R Hey guys, I have a private message script but for some reason when its updating, it turns the value into a blank one from 1 to 3. I have no idea why, but it works with the old statement of deleting, but I changed it to instead update it to 3 because I want to keep the pm in archives. here is the delete PM part. <?php session_start(); header("Location:inbox.php"); $user = $_SESSION['username']; include 'db.php'; //We do not have a user check on this page, because it seems silly to, you just send data to this page then it directs you right back to inbox //We need to get the total number of private messages the user has $sql = mysql_query ("SELECT pm_count FROM users WHERE username='$user'"); $row = mysql_fetch_array ($sql); $pm_count = $row['pm_count']; //A foreach loop for each pm in the array, get the values and set it as $pm_id because they were the ones selected for deletion foreach($_POST['pms'] as $num => $pm_id) { //Delete the PM from the database mysql_query("UPDATE messages SET recieved='3' WHERE id='$pm_id' AND reciever='$user'"); // mysql_query("DELETE FROM messages WHERE id='$pm_id' AND reciever='$user'"); //Subtract a private message from the counter! YAY! //$pm_count = $pm_count - '1'; //Now update the users message count with the new value //mysql_query("UPDATE users SET pm_count='$pm_count' WHERE username='$user'"); } ?> The commented out part at the end, is the old deleting parts but instead changed it to update value. Here is my form that shows checkboxes. I showed the whole code, where it has comments. <?php //This stuff and the while loop will query the database, see if you have messages or not, and display them if you do $query = "SELECT id, sender, subject, message FROM messages WHERE reciever='$user' AND recieved='1'"; $sqlinbox = mysql_query($query); //We have a mysql error, we should probably let somone know about the error, so we should print the error if(!$sqlinbox) { ?> <p><?php print '$query: '.$query.mysql_error();?></p> <?php } //There are no rows found for the user that is logged in, so that either means they have no messages or something broke, lets assume them they have no messages elseif (!mysql_num_rows($sqlinbox) ) { ?> <center><p><b>You havent read any messages</b></p></center> <?php } //There are no errors, and they do have messages, lets query the database and get the information after we make a table to put the information into else { //Ok, Lets center this whole table Im going to make just because I like it like that //Then we create a table 80% the total width, with 3 columns, The subject is 75% of the whole table, the sender is 120 pixels (should be plenty) and the select checkboxes only get 25 pixels ?> <center> <form name="send" method="post" action="delete.php"> <table width="80%"> <tr> <td width="75%" valign="top"><p><b><u>Subject</u></b></p></td> <td width="120px" valign="top"><p><b><u>Sender</u></b></p></td> <td width="25px" valign="top"><p><b><u>Select</u></b></p></td> </tr> <?php //Since everything is good so far and we earlier did a query to get all the message information we need to display the information. //This while loop goes through the array outputting all of the message information while($inbox = mysql_fetch_array($sqlinbox)) { //These are the variables we get from the array as it is going through the messages, we have the id of the private message, we have the person who sent the message, we have the subject of the message, and yeah thats it $pm_id = $inbox['id']; $sender = $inbox['sender']; $subject = $inbox['subject']; //So lets show the subject and make that a link to the view message page, we will send the message id through the URL to the view message page so the message can be displayed //And also let the person see who sent it to them, if you want you can make that some sort of a link to view more stuff about the user, but Im not doing that here, I did it for my game though, similar to the viewmsg.php page but a different page, and with the senders id //And finally the checkboxes that are all stuck into an array and if they are selected we stick the private message id into the array //I will only let my users have a maximum of 50 messages, remeber that ok? Because that's the value I will later in another page //Here is finally the html output for the message data, the while loop keeps going untill it runs out of messages ?> <tr> <td width="75%" valign="top"><p><a href="viewmsg.php?msg_id=<?php echo $pm_id; ?>"><?php echo $subject; ?></a></p></td> <td width="120px" valign="top"><p><?php echo $sender; ?></p></td> <td width="25px" valign="top"><input name="pms[]" type="checkbox" value="<?php echo $pm_id; ?>"></td> </tr> <?php //This ends the while loop } //Here is a submit button for the form that sends the delete page the message ids in an array ?> <tr> <td colspan="3"><input type="submit" name="Submit" value="Delete Selected"></td> <td></td> <td></td> </tr> </table> </center> <?php //So this ends the else to see if it is all ok and having messages or not } ?> So yeah, does anyone know why it updates it to a blank value, from the value 1 in recieved? How can I store data which is in a email to a MySQL db? Currently I'm receiving all enquirers in to my INBOX. I need a way to upload data which is in the mail direct from my email page to a MySQL db. is this possible? or what's the best way to approach this?

Hi guys,
I have a problem with my code.
It connects with the database but it doesn't execute anything.
I am trying to update a value in a table but I really don't know what I am doing wrong.
I am trying to change the price based on the meta_value GF-1370
Thank you very much.
Here is Table (Taken from myphpadmin)
meta_id post_id meta_key meta_value
18538
4356
_sku
GF-1370
18541
4356
_price
2.343
and here is my code:
<?php
$link = mysql_connect('server', 'username', 'password');
if (!$link) {
die('Could not connect: ' . mysql_error());
}
echo 'Connected successfully';
mysql_select_db(wordpress_i12dhflgoa);
$sql="update `wp_pzvy_postmeta` set `_price` = 5 WHERE `_sku` = 'GF-1370'";
?>
Hi guys I hope I am in the right place on this forum, if not I apologise. A have been working with CS-Cart and had so much trouble trying to update product combinations so I searched for help on the data feeds I am using and found that there was a script that would update my products for os-commerce, this has worked out even worse. All I really need is for a script to update one column called amount in a Mysql table by referring to the product_code column, Eg If product_code NS324 is= to 5 ad 5 to the amount column. This sounds simple but I think it might be complex. Here is the Table Generated b\: phpM\Admin 3.4.9 / M\SQL 5.5.20-log SQL quer\: SELECT * FROM `cscart_product_options_inventor\` LIMIT 0, 30 ; Rows: 30 Column1-----------Column2---------------Column3--------------Column4----------Column5-------Column6-------Column7 product_id-----product_code---------combination_hash-----combination-------amount----------temp-----------position --29813--------------NS3455----------- --1447985068-----------738_3059-----------0-----------------N-------------------0 So if I can update the amount column using the product_code would solve all of my problems. So this is what I need to do, I need to add an amount to the amount column related to the product_code NS3455 or update amount or even replace amount it don't matter. Due to the nature of the feeds I receive I cannot use product_id or combination_hash or combination. Please help me do this. Lets see who is the clever one. Thanks for you time For the last few days I have been trying to work out why my code does not update the MySQL database table. Having tried several variation I have the below but cannot see anything wrong. The rest of the program produces the correct results (displaying what is currently on the table) showing it is connecting to the correct table but altering the table is not working. Any help greatly appreciated.

I'm a noob trying to reverse engineer code. I have a script that can retrieve values from a MySQL database (based on a session login that recognizes which user you are) and places those values into the text fields of a form, pre-populating the form. Code: [Select] <?php mysql_connect('localhost', 'db', 'password'); mysql_select_db('users'); $id = mysql_real_escape_string($_SESSION['userid']); $select = "SELECT * FROM user_info WHERE md5(Member_No) = '$id';"; $query = mysql_query($select); if ($row = mysql_fetch_array($query)) { ?> <form> FIRST name: <input type="text" name="First" value="<?php echo stripslashes($row['First']); ?>" LAST name: <input type="text" name="Last" value="<?php echo stripslashes($row['Last']); ?>" > Birthday: <input type="text" name="Birthday" value="<?php echo stripslashes($row['Birthday']); ?>" <input type="submit" value="Submit"> </form> <?php } ?> I want to be able to connect to that same database and update ALL the values (3 in the example above) with the single click of the form button. I think I was told some time ago that it's not possible to update all the values at once? Thanks, ~Wayne Hi All, Please can someone help me with this bit of code. I have a mysql database with a table called 'events'. I have six fields namely 'ID, mxitID, type, message, ts, publish'. I am trying to update the field 'publish' from Yes --> No or if it is already No then back to Yes again. I have two files then main one beacon.php and publish.php Here is the code: beacon.php Code: [Select] <?php // connect to the database include('connect-db.php'); // display data in table // echo "<p><b>View All</b> | <a href='view-paginated.php?page=1'>View by Page</a></p>"; // echo "Select your Carousel: "; // get results from database $result = mysql_query("SELECT * FROM events WHERE type='beacon'") or die(mysql_error()); echo "<table border='1' cellpadding='10'>"; echo "<a href='index.php'>b Back</a><br><br>"; echo "<tr> <th>ID</th> <th>mxitID</th> <th>Type</th> <th>Message</th> <th>Timestamp</th> <th>Published</th> <th>Modify</th></tr>"; // loop through results of database query, displaying them in the table while($row = mysql_fetch_array( $result )) { // echo out the contents of each row into a table echo "<tr>"; echo '<td>' . $row['ID'] . '</td>'; echo '<td>' . $row['mxitID'] . '</td>'; echo '<td>' . $row['type'] . '</td>'; echo '<td>' . $row['message'] . '</td>'; echo '<td>' . $row['ts'] . '</td>'; echo '<td>' . $row['publish'] . '</td>'; echo '<td><a href="publish.php?id=' . $row['ID'] . '"><input name="update" type="submit" id="update" value="Update"></a></td>'; echo "</tr>"; } // close table> echo "</table>"; ?> publish.php <?php // connect to the database include('connect-db.php'); // get id value $id = $_GET['id']; echo "$id"; $sql="SELECT * FROM events WHERE type='beacon'"; $result=mysql_query($sql); $active=($result['publish']=='')?'Yes':'No'; echo "$active"; if ($active='Yes') { $active='No'; } else { $active='Yes'; } $sql = "UPDATE events SET publish='$active' WHERE ID='$id'"; $result = mysql_query($sql); // header("Location: beacon.php"); ?> I cant seem to change the value...any help would be much appreciated. Thank you in advance. MOD EDIT: code tags added. Hi Forum I have this script below which i thought would update multiple rows in my database, but all it does is refresh and revert back to its original data. Im guessing my problem is in my update script but I cant seem to find where I have gone wrong. Any help would be greatly appreciated. <?php $host="*****"; $username="*****"; $password="*****"; $db_name="*****"; $tbl_name="*****"; // Connect to server and select databse. $db = new PDO('mysql:host=' . $host . ';dbname=' . $db_name, $username, $password); // If there is an update, process it. if (isset($_POST['submit'], $_POST['pageorder']) && is_array($_POST['pageorder'])) { $stmt = $db->prepare("UPDATE `$tbl_name` SET `pageorder`=:pageorder WHERE id=:id"); $stmt->bindParam(':id', $id, PDO::PARAM_INT); $stmt->bindParam(':pageorder', $pageorder, PDO::PARAM_STR); foreach ($_POST['pageorder'] as $id => $pageorder) { $stmt->execute(); } echo '<h1>Updated the records.</h1>'; } // Print the form. echo '<form action="' . htmlspecialchars($_SERVER['PHP_SELF']) . '" method="post">'; foreach ($db->query("SELECT `id`, `pageorder`, `pagetitle`, `linklabel` FROM `$tbl_name` ORDER BY `pageorder`") as $row) { echo '<input type="text" pageorder="pageorder[' . (int)$row['id'] . ']" value="'. htmlspecialchars($row['pageorder']) . '" />'; echo '<input type="text" pagetitle="pagetitle[' . (int)$row['id'] . ']" value="'. htmlspecialchars($row['pagetitle']) . '" />'; echo '<input type="text" linklabel="linklabel[' . (int)$row['id'] . ']" value="'. htmlspecialchars($row['linklabel']) . '" /><br />'; } echo '<input type="submit" name="submit" value="Update" /></form>'; ?> |
