PHP - Help With $_post & $_get!
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! If any more info is needed, let me know.

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! 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. 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 $DateReq ?> Any reason why the thank you page isn't calling the values? I exhaustively checked it against a working form I have on another site, and the code seems to be, well, identical. Not getting an error, just get empty space where the values should be. hey guys basically i have a form which searches my news <form action="" method="GET"> <label for="search">Search: </label><input name="search" id="search" type="text" /> <input value="Search" type="submit" /> </form> and im not sure the best way around this or if im going around this the right way but when i access http://localhost/news/seach (search form) and press submit after entering a query i want the action to be http://localhost/news/seach/search query value here i hope ive explained well enough and someone could help me with this...thank you I recently had a customer say that one of my forms isn't working. For some reason the ID number is getting lost when she submits the form. The form code looks like: ... print "<form method='post' name='form' action='update.php'>"; ... print "<input type='hidden' name='id' value=\"$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.
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.
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"]; 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 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 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!
