PHP - Losing $_get And $_post Data
I recently had a customer say that one of my forms isn't working. For some reason the ID number is getting lost when she submits the form.
The form code looks like: ... print "<form method='post' name='form' action='update.php'>"; ... print "<input type='hidden' name='id' value=\"$id\" />"; print "<input type='submit' name='submit' value=\"Save Session\" />"; print "</form>"; ... And the PHP code that gets executed looks like: ... //GET SESSION ID if(isset($_GET['id'])) { //ID from HTML link, before updates have been made $id = $_GET['id']; } elseif(isset($_POST['id'])) { //ID from form, after updates have been made $id = $_POST['id']; } else { $id = ''; } //IF SESSION ID IS VALID if(preg_match("/^\d+$/", $id)) { ... //ELSE, INVALID ID } else { $msg = "<span class='errorText'>Session ID not found or invalid.</span>"; } ... For some reason she usually gets the "Session ID not found..." error when submitting the form. Do you see any problems with the above code? Note that she has been able to sucessfully use the form before (in the same day); we have nearly 1,800 records submitted using these forms; and I am unable to duplicate the issue. So I'm at a loss on what to do next. Also, she talked with her IT person about the form. The IT person was able to submit data on his computer. So he reset her Internet options which seemed to fix the problem on her end temporarily. Note that she is using IE 7. She also said that she doesn't have access to any other browsers. I'm tempted to chalk this up as a personal computer issue, but wanted to get your input first. Similar Tutorials
So maybe this is normal, or maybe there is a "better way." The only simple solution appears to be to always save $_POST data to $_SESSION["post"] on the off-chance some visitor some day ever decides to do a $_GET request from a referral link.
3 weeks of my life has been lost to correcting the neverending 'illegal string offset' and 'undefined index' errors etc. by making sure every last variable is declared... Anyway, blah blah blah, that's my rant. Is there a better way? Or is this "how everybody does it?" It seems stupid to have to do all of this.
Hi, I am a curious fellow just beginning to use PHP. I understand the basics of what the $_GET and $_POST superglobals do, and how we can use them to retrieve data after form submission. I also know that since $_GET and $_POST are just associate arrays, we can create our own values in both $_GET and $_POST by writing statements like $_POST['variable'] = "value". I am wondering if it is at all possible to send data beyond form data by adding new key/value pairs into $_GET and $_POST. So for example, if I had a form that transferred username/password through Post, would it be possible for me to include further data by just saying $_POST['formtype'] = "house_insurance_form"? Basically what I'm getting at is trying to physically add your own data to $_POST or $_GET that you could pull from the next page where the form redirects to. In other words, can I send data beyond form data using these superglobals? I know I can do this with $_SESSION, but could I do it through $_POST or $_GET? I haven't been able to accomplish this, and I was just wondering if someone could give me an in-depth explanation of how this might work or how this is not possible. I would really really really appreciate it. Best Regards, -Sky Hello guys. I'm trying to improve my control panel system. I have this page where you input a player's name and when you hit "Search" it will display that user's information. Ok. This is the code: Code: [Select] <form action="ShowStats.php" method="post"> <li><font color="#FF9933"><b>User's Name:</b></font> <input type="text" name="User" /></li> <p> </p> <p> </p> <input type="submit" value="Search" /></form>That's when you input the player's name and the Search button. Once you hit that button, I want the Address bar to display something like this: "www.test.com/ShowStats.php?User=SEARCHED_USER" Here's the $_POST ( and "fetch" user's info ) function inside "ShowStats.php" include("database.php"); if(!$con) { die('Could not connect: ' . mysql_error()); } $user = $_POST["User"]; $escuser = mysql_real_escape_string($user); $result = mysql_query("SELECT * FROM playerinfo WHERE user = '$escuser'"); $username_exist = mysql_num_rows($result); if($username_exist == 0) { echo('<b><font color="#C41F1F">That username does not exist</b></font>'); echo('<p><center><font face="Arial" color="#000080" size="2"><b><a href="http://yu-ki-ko.com/fsns/Stats.php">Go back</a></b></center></font></p>'); die; } $row = mysql_fetch_row($result); All I want is that when a user searches for the player, the address bar will be displayed like: "www.test.com/ShowStats.php?User=SEARCHED_USER" Thanks!

I am wanting to make a form where they fill out their name and what color they use. What is wrong? Hi guys i am a PHP newbie trying to learn from the beginning. I am reading a php book and i can't get past a particular example because $_GET and $_POST just won't work. Below is the code i am working with: HTML File <form action="welcome1.php" method="get"> <div> <label for="firstname">First name: <input type="text" name"firstname" id="firstname"/></label> </div> <div> <label for="lastname"> Last name: <input type="text" name="lastname" id="lastname"/> </label> </div> <div> <input type="submit" value="GO" /> </div> PHP file <?php $firstname = $_GET['firstname']; $lastname = $_GET['lastname']; print 'Welcome to our website, ' . htmlspecialchars($firstname, ENT_QUOTES, 'UTF-8') . ' ' . htmlspecialchars($lastname, ENT_QUOTES, 'UTF-8') . '!'; ?> I am working on a windows pc with Vista home edition installed. I run a localhost server installed via XAMMP. Please this has been a recurring problem for me. Each time i get to this stage in the past i always get stuck. $_GET and $_POST just does not work for me. Please heeeelp! My form values are not posting on my thankyou.php page. I'm sure it's a simple fix. Here's some code from reservation.php . form action="CGI/gdform.php" method="post" enctype="application/x-www-form-urlencoded" name="formres" id="formres"> <input type="hidden" name=" redirect" value="ThankYou.php"> <label><span class="style12">Your Name: <input type="text" name="txtName" id="Name" /> </span></label> ... <p class="style12"><span id="sprytextfield10"> <label>Date of Special Event: <input type="text" name="DateReq" id="DateReq" /> </label> <?php $txtName = $_GET[txtName]; ... $DateReq = $_GET[DateReq]; ?> </form> On my thankyou.php: <body> <?php $txtName = $_POST[txtName]; ... $DateReq = $_POST[DateReq]; ?> and a little lower down... <?php echo $txtName ?> ... <?php echo $DateReq ?> Any reason why the thank you page isn't calling the values? I exhaustively checked it against a working form I have on another site, and the code seems to be, well, identical. Not getting an error, just get empty space where the values should be. Hi, I do not have a problem with specific code but rather code design/technique. I am not able to articulate the problem very well but here goes. I am building a [mostly] object oriented PHP store as a personal project to improve my PHP skills. However I'm running into some problems concerning my sorting, pagination and filtering facilities. I've tried to use $_GET to store the following: Page being viewed by the user Category (e.g. fruit or vegetables) Sort method (e.g price ascending, descending etc.) When the user clicks on a link to another page for example, I must append the page number to the URL, something like "index.php?page=2" but the other $_GET parameters are lost unless I do something like: Code: [Select] <a href=\"index.php?cat=".$_GET['cat']."&sort=".$_GET['sort']."&page=".($this->pageNum+1)."\">Next-> </a> This means whenever there is a link or form submission I must find a way to carry over all those parameters to ensure the page and category are remembered, otherwise the user is returned to page 1 and the main category. It's a mess and has become too confusing with the introduction of other pages. Clearly, I'm doing it all wrong. $_GET parameters alone are not a good solution here, at least how I'm using them. So I ask of you, what's the correct way to store information such as page number, sorting method and category? Must I use $_SESSIONS and if so how? Thanks. hey guys basically i have a form which searches my news <form action="" method="GET"> <label for="search">Search: </label><input name="search" id="search" type="text" /> <input value="Search" type="submit" /> </form> and im not sure the best way around this or if im going around this the right way but when i access http://localhost/news/seach (search form) and press submit after entering a query i want the action to be http://localhost/news/seach/search query value here i hope ive explained well enough and someone could help me with this...thank you Is this an effective way of accessing the $_GET and $_POST properties? I can see that the native $_GET function has been looped through so that $varName would be for example "username" and $value would be "Jeremy". Then they are both stored into an array called $getVars? Is this the best way of doing it, if not then why? foreach($_GET as $varName=>$value) $getVars[$varName]=trim(clean($value, 100)); foreach($_POST as $varName=>$value) $postVars[$varName]=trim(clean($value, 100));[/php] Kind regards, laanes I have a php search page that takes form data to create its queries, then reload the original search page. The form is long, so there are numerous $_POST's to convert to variables for use in the query. I've looked at "extract" and a few other code snippets. But it's a form and I don't want any security issues. I'm hoping there's a "foreach" solution, but I'm a beginner. What's a proper way to to simplify this: $s1 = $_POST["s1"]; $s2 = $_POST["s2"]; $s3 = $_POST["s3"]; $s4 = $_POST["s4"]; $s5 = $_POST["s5"]; $s6 = $_POST["s6"]; $s7 = $_POST["s7"]; $s8 = $_POST["s8"]; $s9 = $_POST["s9"]; $s10 = $_POST["s10"]; $s11 = $_POST["s11"]; $s12 = $_POST["s12"]; User clicks on a url, ie: example.com/AEQ438J When I perform this in the code below: Code: [Select] $referrer = $_GET['_url']; // echo $referrer displays the referrer ID contents correctly as "AEQ438J" if ( ! empty($referrer)) { $mysqli->query("UPDATE coming_soon_emails SET clicks = clicks + 1 WHERE code='" . $referrer ."'"); } // this also updates the database correctly as it should if (!empty($_POST['email'])){ // echo $referrer displays the referrer ID contents as BLANK. It should display "AEQ438J"! ..... $referrer displays correctly BEFORE if($_POST['form']), however during the if($_POST['form']) $referrer is empty. How can I fix my code so that $referrer is not empty during the time the user posts their email address in the form? Thank you!

It seems so simple, but I've been staring at it and toying with it for ages, so I figured I'd post here. I have a variable called "$isTaken" that seems to be losing its value in an essential step in my function. Take a look. function subdomainTaken($inputtedSubdomain) { //Initialize $isTaken to 'true' $isTaken = true; echo "isTaken STARTS AS: <i>" . $isTaken . "</i><br />"; //FOR TESTING PURPOSES ONLY. VARIABLE HAS VALUE HERE //Check subdomain in database $subdomainDBQuery = mysql_query("SELECT * FROM `companies` WHERE company_subdomain = '$inputtedSubdomain'"); $foundResult = mysql_num_rows($subdomainDBQuery); if ($foundResult > 0) { $isTaken = true; } else { $isTaken = false; } return $isTaken; } By the time I get to the if statement, $isTaken has no value. I've echoed it to be sure. Any ideas? Thanks, Frank Alright, I've spent over a week trying to fix this now - And Im getting frustrated! I asked at other forums, I asked co-workers and I asked friends-of-friends, and nobody can explain what happens. Let's take a look at this first: $name = mysql_real_escape_string($_POST['name']); mysql_query(sprintf("UPDATE em_users SET name='%s' WHERE id='" . $in_user['id'] . "'", $name)); This will insert NO data on the Name field in the database. Obviously, I thought the $_POST variable wasn't passed correctly, but echo'ing it just before the query WILL show data. And as I said, I tried everything possible for the last week. Switching variables, adding static text on the $name variable instead of using the $_POST content (this does work). I used very very simple test data on the form, such as my name "Mark" or "test" and "hey". The query is correctly executed everytime. The truely WEIRD thing is, if I ensure there is content in $name before executing the query it will work as expected everytime. Like this: $name = mysql_real_escape_string($_POST['name']); $name && mysql_query(sprintf("UPDATE em_users SET name='%s' WHERE id='" . $in_user['id'] . "'", $name)); Of course I could do this, but I want to know why my code does or doesn't work + it's a lot of work to do for something that worked fine a week ago. It has spread to a lot of forms on my website that $_POST variables aren't processed correctly - and it happened out of nowhere. Even on codes that havnt changed in months. I really need help on fixing this! This project has been in development for nearly two years, and without a fix it's pretty much lost Hey all, I am having a situation where I have a singleton class with a static array in it. I insert an element into that array, and then I redirect the user to another page. At that page, I then retrieve that array (it's stored in the session vars), but the array is then empty when I retrieve it. I can't figure out why. Here are some pertinent code snippets. First, the class with the static array: class Logger { private static $instance = NULL; private static $messages = array(); //Private constructor to prevent this class from being instantiated multiple times private function __construct() { } //The clone function is private to prevent cloning of this class private function __clone() { } //Returns the singleton instance of this class public static function GetInstance() { if (!self::$instance) { self::$instance = new Logger; } return self::$instance; } public static function GetMessageCount() { return count(self::$messages); } public static function LogMessage($new_message) { self::$messages[] = $new_message; } public static function GetMessages() { return self::$messages; } public static function ClearMessages() { self::$messages = array(); } } Here is the code where I insert something into the aformentioned array (the process is that a user tries to log in, but the login fails, and so we insert a message into the array saying that the login credentials failed). //Retrieve the message logging instance from the session data to be able to pass messages to the user. $message_log = $_SESSION['user_messages']; $user = $_SESSION['user_account']; //Create a new instance of the database management class and //try to connect to the database $dbm = new DBM(); if ( !$dbm->isConnected() ) { $message_log::LogMessage("We are sorry, but we are unable to access the database at this time. Please try again later."); } else { //Retrieve the user login information $useremail_dirty = $_POST['useremail']; $password_dirty = $_POST['userpassword']; //Check to see if the email we were given exists in the database, and if the password matches $doesPasswordMatch = $dbm->doesPasswordMatch ( $useremail_dirty, $password_dirty ); if ( $doesPasswordMatch ) { //Correct login information was received. Login the user and redirect appropriately. $user->Login(); header ( "Location: ".BASE_URL."/userpage.php" ); exit; } else { //If an incorrect email or password was given, report that information to the user. $message_log::LogMessage("Incorrect login information."); } } //The user has failed to login. Redirect to the appropriate page. header ( "Location: ".BASE_URL."/loginfailed.php" ); And finally, given an unsuccessful login attempt, this is where I pick back up the array of messages to display the messages to the user: $message_log = $_SESSION['user_messages']; $all_messages = $message_log::GetMessages(); print $message_log::GetMessageCount()."<br>"; print count($all_messages)."<br>"; foreach ($all_messages as $message_string) { $prepared_string = prepare_text_for_html_output($message_string); echo $prepared_string."<br>"; } $message_log::ClearMessages(); Unfortunately, the "all_messages" variable has nothing in it...it's like the messages that I logged in the previous PHP script never even existed. I am calling session_start, so don't worry about that (even though it's not seen in these code snippets). What could be going wrong? This topic has been moved to JavaScript Help. http://www.phpfreaks.com/forums/index.php?topic=323252.0 I'm trying to add voucher codes to my shopping basket. When someone submits a voucher code it adds ?vouchercode=WHATEVERTHECODE to the URL. I then $_GET this data and store is as $_SESSION['vouchercode']. The problem is, on the next page it $_GET's the ?vouchercode again, which is this time blank, and sets the session to blank as well. Any help?

Any help to achieve what I want will be appreciated. Thank you. I have a web page that uses $_POST to pass the ID from web page to web page as they fill out forms using$ID=$_POST['id']The last page of the form passes this and other information to a php page that inserts the information that was passed into a database I have set up and then redirects back to the first page of the form. This is what I have so far. <?php // Change to the URL you want to redirect to $URL="Start.php"; header ("Location: $URL"); $ID=$_POST['id']; ?> What I want to happen however is when it redirects, I want it to pass the ID information back to the main page again as well. Can anyone help me out? Hi, Firstly, I am a complete newcomer to PHP though I am enjoying my first tentative steps into learning the language! I have been searching Google for hours now to try and find a simple solution to a problem I just can't seem to figure out, though I thought would be easy to find? I have found a lot of very informative solutions to other questions on this forum so figured it was the best one to join? My question is: I have built and can interact with a simple database and now populate a page with usernames in a list. Each one is a link which, when clicked sends the username to another page. On this page I use the $_GET function and see the username displayed ok. What I can't figure out is how to then display other information about them from the fields in the database identified with that user? Any help would be greatly appreciated as this is driving me nuts! Also can anyone suggest a good book for learning PHP? There are lots out there but the reviews on Amazon seem to always talk about coding errors in print etc. so I really don't know which one to buy? FF I've been poking around the Internet for the answer to this without any success. This query APPEARS to run, but NOTHING GETS INSERTED. The QuestionID in the Questions table is set to auto-increment, so I only need the QuestionText data for this table. the QuestionID in the Answers table is not because there might be four or five options per question. The snippets of code under consideration is pasted below snipped from index.php: Code: [Select] <form action="./newquestion.php" method="post"> Question Text:<br><input type="text" size=100 name="QuestionText" /><br><br> <input type="submit" value="Enter next question"/> </form> Then snipped from newquestion.php mysql_select_db(quiz); $query = mysql_query("INSERT INTO Questions VALUES ('$_POST[QuestionText]'"); $result = mysql_query($query); Thank you all. I'm sure I'll learn this pretty fast, but I still need a little help. |
