PHP - One Field Not Updating After Update Query
Hi there. I'm totally new (about a week!) with php and mysql and am encountering a problem that perhaps someone can help me with?
I've looked through to see if a similar problem has appeared or been solved, but without success, so apologies if I am repeating something.
In php I am trying to update 7 fields from a form from which a user has edited/modified any of the fields in a chosen record (except id).
Here is the code:
$id=$_GET['id'];
Similar TutorialsI have the following PHP script to update two time/date fields in the database. When i run this the fields are not updated. Can anyone see where i m going wrong. <?php $con = mysql_connect("localhost","dbname","dbpassword"); if (!$con) { die('Could not connect: ' . mysql_error()); } echo 'Connected successfully'; mysql_select_db("my_db", $con); mysql_query("UPDATE msm_content SET created = '2011-01-02 00:00:00', modified = '2011-01-01 00:00:00'"); echo 'Query Updated successfully'; mysql_close($con); ?> Your guidance is much appreciated. I have a form that allows my client to update some products. Now the products are simple just basic info and 1 picture. I have set this up so they can edit the products and change the information, having done this many times in the past, but now hit a puzzling block that I am baffled. The client when editing is presented with the form with the information pulled from the database and the form fields loaded with that data ready to edit. The image can either be left alone or they can choose to upload a new image. They are shown the image they currently have stored in the database. The problem I have is EVEN if they decide not to upload an image and change other information, when the submit the form it must be sending a blank value for the image somewhere as it is updating the database and removing the image reference as if it has been removed. I have an if/else statement based on the form to perform 2 different queries for the update in mysql. Here is the code for the form update, as you can see the image should not update?? Please help?? if ($_SERVER['REQUEST_METHOD'] =='POST') { //This stops SQL Injection in POST vars foreach ($_POST as $key => $value) { $_POST[$key] = mysql_real_escape_string($value); } // **************************** THIS IS FOR NO NEW IMAGE ******************************** if ($_SERVER['REQUEST_METHOD'] =='POST' && empty($_FILES['product_image']['name'])) { # setup SQL statement for no new image $SQL = " UPDATE products SET product_title = '{$_POST['product_title']}', product_description = '{$_POST['product_description']}', standard_price = '{$_POST['standard_price']}', deluxe_price = '{$_POST['deluxe_price']}' WHERE product_id = '{$_REQUEST['product_id']}' "; } // **************************** THIS IS FOR A NEW IMAGE ******************************** else { // Check the image type is a jpeg or gif for the image. if (($_FILES['product_image']['type'] != "image/gif") && ($_FILES['product_image']['type'] != "image/jpeg") && ($_FILES['product_image']['type'] != "image/pjpeg")) { echo "<FONT FACE=\"Verdana\"><SPAN CLASS=\"content\">You have chosen not to upload a <b>Product Image</b>.<BR></SPAN>" ; } elseif ($_FILES['product_image']['size'] > 100000) { echo "<FONT FACE=\"Verdana\"><SPAN CLASS=\"content\">The file size is bigger than 300kb.<BR></SPAN>" ; } else { move_uploaded_file($_FILES['product_image']['tmp_name'], "/httpdocs/product_images/".$_FILES['product_image']['name']) ; echo "<FONT FACE=\"Verdana\"><SPAN CLASS=\"content\"><B>Your front image has successfully uploaded.</B><BR></SPAN>" ; } } # setup SQL statement for update $SQL = " UPDATE products SET product_title = '{$_POST['product_title']}', product_description = '{$_POST['product_description']}', standard_price = '{$_POST['standard_price']}', deluxe_price = '{$_POST['deluxe_price']}', product_image = '{$_FILES['product_image']['name']}' WHERE product_id = '{$_REQUEST['product_id']}' "; } #execute SQL statement $result = mysql_db_query( *****,"$SQL",$connection ); # check for error if (!$result) { echo("ERROR: " . mysql_error() . "\n$SQL\n"); } Hi all, I have the following MySQL insert query: Code: [Select] $insert= mysql_query ("INSERT INTO tablename (column1,`".$EXPfields."`) VALUES ('$something','".$EXPvalues."')"); where $EXPfields is an array of table-field-names and $EXPvalues is an array of table-field-values. Now I want to write an equivalent query, but using UPDATE instead of INSERT INTO, but I don't want to write out all the field names/values separately, but again want to use $EXPfields and $EXPvalues. So something like this: Code: [Select] $update = mysql_query ("UPDATE tablename SET (column1,`".$EXPfields."`) = ('$something','".$EXPvalues."') WHERE .... "); Is this possible? If so, what is the proper syntax? Thanks! Hi: I'm going crazy trying to do the following: I'm making a job registration process where the user registers on one php page to the website, must acknowlege and email receipt using an activate php page, then is directed to upload their C.V. (resume) based on the email address they enter in the active page output. I then run an upload page to store the resume in teh MySQL db based on the users email address in the same record. If I isolate the process of the user registering to the db, it works perfectly. If I isolate the file upload process into the db, it works perfect. I simply cannot upload teh file to the existing record based on teh email form field matching the user_email field in the db. With the processes together, teh user is activated, but teh file is not uploaded. Maybe I've simply been at this too long today, but am compeled to get through it by end day. If anyone can help sugest a better way or help me fix this, I will soo greatly appreciate it. My code is as follows for the 2 pages. ---------activate.php------- <?php session_start(); include ('reg_dbc.php'); if (!isset($_GET['usr']) && !isset($_GET['code']) ) { $msg = "ERROR: The code does not match.."; exit(); } $rsCode = mysql_query("SELECT activation_code from subscribers where user_email='$_GET[usr]'") or die(mysql_error()); list($acode) = mysql_fetch_array($rsCode); if ($_GET['code'] == $acode) { mysql_query("update subscribers set user_activated=1 where user_email='$_GET[usr]'") or die(mysql_error()); echo "<h3><center>Thank You! This is step 2 of 3. </h3>Your email is confirmed. Please upload your C.V. now to complete step 3.</center>"; } else { echo "ERROR: Incorrect activation code... not valid"; } ?> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta content="text/html; charset=utf-8" http-equiv="Content-Type" /> <title>Job application activation</title> </head> <body> <center> <br/><br/><br/> <p align="center"> <form name="form1" method="post" action="upload.php" style="padding:5px;"> <p>Re-enter you Email : <input name="email" type="text" id="email"/></p></form> <form enctype="multipart/form-data" action="upload.php" method="POST"> <input type="hidden" name="MAX_FILE_SIZE" value="4000000"> Upload your C.V.: <input name="userfile" type="file" id="userfile"> <input name="upload" type="submit" id="upload" value="Upload your C.V."/></form> </p> </center> </body> </html> --------upload.php---------- <?php session_start(); if (!isset($_GET['usr']) && !isset($_GET['code']) ) { $msg = "ERROR: The code does not match.."; exit(); } if(isset($_POST['upload']) && $_FILES['userfile']['size'] > 0) { $fileName = $_FILES['userfile']['name']; $tmpName = $_FILES['userfile']['tmp_name']; $fileSize = $_FILES['userfile']['size']; $fileType = $_FILES['userfile']['type']; $email = $_POST['email']['user_email']; $fp = fopen($tmpName, 'r'); $content = fread($fp, filesize($tmpName)); $content = addslashes($content); fclose($fp); if(!get_magic_quotes_gpc()) { $fileName = addslashes($fileName); } include 'reg_dbc.php'; $query = "UPDATE subscribers WHERE $email = user_email (name, size, type, content ) ".

The code i think handles this is below. <input type="text" id="uuser_address" name="uuser_address" value="<?php echo("$slide[address]"); ?>"><br /><input type="text" id="uuser_town" name="uuser_town" value="<?php echo("$slide[town]"); ?>"><br /><input type="text" id="uuser_county" name="uuser_county" value="<?php echo("$slide[county]"); ?>"><br /><input type="text" id="uuser_postcode" name="uuser_postcode" value="<?php echo("$slide[postcode]"); ?>"></div> can anyone tell me why this is updating all the address fields other than the postcode? thanks, gavin Okay, I have a useredit page in where a user can manage their account info. All the text field and SQL connections work fine, and they all update perfectly. But when I go ahead and add my own text field (first name) and hit submit, it says success - but in my SQL it hasn't actually updated ... What the Ef? Here are my snippets of my codes: --useredit.php-- <form action="process.php" method="POST"> <input type"text" name"firstname" value="<? if($form->value("firstname") == ""){ echo $session->userinfo['firstname']; }else{ echo $form->value("firstname"); } ?>"> <input type="hidden" name="subedit" value="1"> <input type="submit" value="Edit Account"> --process.php-- function procEditAccount(){ global $session, $form; /* Account edit attempt */ $retval = $session->editAccount($_POST['curpass'], $_POST['newpass'], $_POST['email'], $_POST['firstname']); /* Account edit successful */ if($retval){ $_SESSION['useredit'] = true; header("Location: ".$session->referrer); } --session.php-- function editAccount($subcurpass, $subnewpass, $subemail, $subfirstname){ global $database, $form; if($subfirstname){ $database->updateUserField($this->username,"firstname",$subfirstname); } --database.php-- function updateUserField($username, $field, $value){ $q = "UPDATE ".TBL_USERS." SET ".$field." = '$value' WHERE username = '$username'"; return mysql_query($q, $this->connection); } If you need to see more code, let me know. Would appreciate the help, thanks! Ollie! Hello all,
Based on the suggestion of you wonderful folks here, I went away for a few days (to learn about PDO and Prepared Statements) in order to replace the MySQLi commands in my code. That's gone pretty well thus far...with me having learnt and successfully replaced most of my "bad" code with elegant, SQL-Injection-proof code (or so I hope).
The one-and-only problem I'm having (for now at least) is that I'm having trouble understanding how to execute an UPDATE query within the resultset of a SELECT query (using PDO and prepared statements, of course).
Let me explain (my scenario), and since a picture speaks a thousand words I've also inlcuded a screenshot to show you guys my setup:
In my table I have two columns (which are essentially flags i.e. Y/N), one for "items alreay purchased" and the other for "items to be purchased later". The first flag, if/when set ON (Y) will highlight row(s) in red...and the second flag will highlight row(s) in blue (when set ON).
I initially had four buttons, two each for setting the flags/columns to "Y", and another two to reverse the columns/flags to "N". That was when I had my delete functionality as a separate operation on a separate tab/list item, and that was fine.
Now that I've realized I can include both operations (update and delete) on just the one tab, I've also figured it would be better to pare down those four buttons (into just two), and set them up as a toggle feature i.e. if the value is currently "Y" then the button will set it to "N", and vice versa.
So, looking at my attached picture, if a person selects (using the checkboxes) the first four rows and clicks the first button (labeled "Toggle selected items as Purchased/Not Purchased") then the following must happen:
1. The purchased_flag for rows # 2 and 4 must be switched OFF (set to N)...so they will no longer be highlighted in red.
2. The purchased_flag for row # 3 must be switched ON (set to Y)...so that row will now be highlighted in red.
3. Nothing must be done to rows # 1 and 5 since: a) row 5 was not selected/checked to begin with, and b) row # 1 has its purchase_later_flag set ON (to Y), so it must be skipped over.
Looking at my code below, I'm guessing (and here's where I need the help) that there's something wrong in the code within the section that says "/*** loop through the results/collection of checked items ***/". I've probably made it more complex than it should be, and that's due to the fact that I have no idea what I'm doing (or rather, how I should be doing it), and this has driven me insane for the last 2 days...which prompted me to "throw in the towel" and seek the help of you very helpful and intellegent folks. BTW, I am a newbie at this, so if I could be provided the exact code, that would be most wonderful, and much highly appreciated.
Thanks to you folks, I'm feeling real good (with a great sense of achievement) after having come here and got the great advice to learn PDO and prepared statements.
Just this one nasty little hurdle is stopping me from getting to "end-of-job" on my very first WebApp. BTW, sorry about the long post...this is the best/only way I could clearly explaing my situation.
Cheers guys!

I must be using the wrong search terms in google cause I cant find out how to update a field to a blank spot. trying to make name blank. I thought it was just " " hope someone can please help me with this Code: [Select] mysql_query("UPDATE users SET name = '".mysql_real_escape_string "."' WHERE id = '".mysql_real_escape_string($_SESSION['user_id']))."'"; I have this code to change the validity date of an account. I do a check against timestamp and current validity which works fine. Then I have radio buttons you can check to choose to extend with one, three, six or 12 months through a form and a post variable - they work too. When I write the variables out they look fine but when I want it in my database - nothing happens! I mean the original data is never changed. Can you see what is wrong? I tried changing the data type from date to datetime to timestamp with the same result. I suppose I will learn something new from phpfreaks today again. Code is here for the 12 month radio button: Code: [Select] $newdate = strtotime ( '+12 months' , strtotime ($fromDate) ) ; $newdate = date ('Y-m-d H:i:s', $newdate ); echo "$newdate"; $query = "UPDATE TABLE user_data SET paid_days='$newdate' WHERE user='$user'"; mysql_query($query);When I write the variable $newdate it shows up as 2013-01-10 21:55 (right now) which seems like a valid format to me. Do I need to convert it somehow? I need some help with updating the database table with the correct selection from that box. I have a dropdown box. This is actually a list from the images in a curtain directory. here the code I used: <?php $dhandle = opendir('../images/Vessels/'); $files = array(); if ($dhandle) { // loop through all of the files while (false !== ($fname = readdir($dhandle))) { if (($fname != '.') && ($fname != '..') && ($fname != basename($_SERVER['PHP_SELF']))) { $files[] = (is_dir( "./$fname" )) ? "(Dir) {$fname}" : $fname; } } closedir($dhandle); } So when inserting a new record I can use the dropdownbox to populate the correct field. Database: Id, Vesselname, Image, more, andmore There is a section where an authorized user can upload an image to the directory. This image will then be available in dropdown when the need to add a new vessel (in this case) The problem that I have is, when I later what to update the vessel, I want that same dropdownbox to be showing the correct imagename as "selected". How can I do that? This is what I have been expirementing with sofar: <?php require_once('../Connections/bgf_db.php'); ?> <?php $dhandle = opendir('../images/Vessels/'); $files = array(); $selectedFile = "mare.jpg"; if ($dhandle) { // loop through all of the files while (false !== ($fname = readdir($dhandle))) { if (($fname != '.') && ($fname != '..') && ($fname != basename($_SERVER['PHP_SELF']))) { $files[] = (is_dir( "./$fname" )) ? "(Dir) {$fname}" : $fname; } } closedir($dhandle); } if (!function_exists("GetSQLValueString")) { function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "") { if (PHP_VERSION < 6) { $theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue; } $theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue); switch ($theType) { case "text": $theValue = ($theValue != "") ?

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'] .

Thank you in advance. MOD EDIT: code tags added. This topic has been moved to MySQL Help. http://www.phpfreaks.com/forums/index.php?topic=351353.0 I created this code to upload a member's main picture on his member page on website. 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. why is it not updating? <?php $_POST['email']; $_POST['submit']; if (isset($_POST['submit'])) { /*$sql =" UPDATE class_members SET email ='".$_POST['email']."', WHERE S_UID ='".$_POST['mem_id']."' ";*/ $result = mysql_query("UPDATE class_members SET email ='".$_POST['email']."', WHERE mem_id='".$_POST['mem_id']."'") or die(mysql_error()); } ?> Hi all, for my website ive got a fuel station which ive coded so users can fill up there there car fuel tanks, but the code all works part from one part of it. The code: The part of the code which isnt working: <?php $usermoney = $fetch->money; $costs2 = $fetch_fuelstation->price * $fueldiff; if ($costs2 > $usermoney){ echo "You dont have enouth money."; } elseif ($costs2 <= $usermoney){ $nmoney = $usermoney - $costs2; mysql_query("UPDATE users SET money='$nmoney' WHERE username='$username'") or die (mysql_error()); } ?> Ive got a varibal called $usermoney which selects the users current money from the database, but what im trying todo is take the fuel price away from there current money, but its not subtracting the money as it should. Anyone see why its not taking the money? Thanks. How should it look if I want to make a query where a field value should be lower than another field? Code: [Select] ....WHERE total_points<max_points"); Hey, Im needing some help with an update form that I have created using PHP/MySQL. Basically the form is working great (updating records, retrieving records and showing errors) but there is a problem with the errors. If there are no errors and I edit the existing text input values, the database updates fine. However if I edit the existing text input values and there is an error, the edited input values dont save, they revert back to the values of the database. I understand why this is happening, its because the text inputs are set to show the values of the database so if i edit the existing values and an error occurs or the page is refreshed, the values revert back to the database values. However id like it so that if any text in the text field have been edited and an error occurs, the text stays to how it is until the user by passes any errors and then the database is updated. Hopefully this makes sense. I have attached the php page just incase anybody wants to look into it but any help would be much appreciated! Also, im not looking for someone to just to fix this for me but if someone knows my problem and can guide me in the right direction, that would be great. |
