PHP - Header Output Issues
Hello,
I'm creating a pretty simple user registration script. The user fills out 5 forms, submits, and if the data is valid he will be redirected to a verify script. Now I have a bit of an issue, I want to send an verification e-mail to the users e-mail address with a verification code before redirecting him to the verify page. The thing is that I've redirecting him within the header, which doesn't allow me to output the verification email. Is there any easy way around this? Regards Similar TutorialsDears, I want to output an image by imagepng function in between some texts. For that I used the below codes Code: [Select] // Above this i set image properties by GD functions in $img variable ob_start(); echo "Text 1"; header("Content-type:image/png"); imagepng($img); imagedestroy($img); header("Content-type:text/html"); echo "Text 2"; ob_end_flush(); But unfortunately the image is not visible, rather it turns into some abnormal characters. But if I get rid of the texts (like below), image is printed perfectly. Code: [Select] // Above this i set image properties by GD functions in $img variable ob_start(); header("Content-type:image/png"); imagepng($img); imagedestroy($img); ob_end_flush(); Anybody please help. Hi i turned my output_buffering to true on my php.ini because i need some of its features for trailing the system my problem now is when im getting .csv file using header function, it seems that it gives me the source code of the interpreted code instead of the expected .csv contents. Here is the source code echo $who; echo $ecrn; $myFile = "($who)$info_value[RecordName]-$ecrn"; header('Content-Type: text/csv; charset=utf-8'); $content = "Content-Disposition: attachment; filename=".$myFile.".csv"; header($content); $output = fopen('php://output', 'w'); $sql = "SELECT * FROM classrecordvalue"; $query = mysql_query($sql); // loop over the rows, outputting them while ($row = mysql_fetch_array($rows)) fputcsv($output, $row); im just wondering does output_buffering true in php.ini affect the output here? if so any other suggestions there of how i can download .csv files using php? thank you much for the people who will help I am having a problem with my login page when I set cookies I get this error. Quote Warning: Cannot modify header information - headers already sent by (output started at /login.php:10) in /loginform.php on line 66 Warning: Cannot modify header information - headers already sent by (output started at /login.php:10) in /loginform.php on line 67 Warning: Cannot modify header information - headers already sent by (output started at /login.php:10) in /loginform.php on line 68 Warning: Cannot modify header information - headers already sent by (output started at /login.php:10) in loginform.php on line 72 I do have ob_start() at the beginning and ob_flush() and the end but i still get the error <?phpinclude('config.php');ob_start();@session_start();if (!isset($_POST['login'])) {?><form method="post" action="<?php $_SERVER['PHP_SELF'] ?>"> <fieldset> <legend>Login</legend> <table> <tr> <td>Email </td> <td><input type="text" name="email" /></td> </tr> <tr> <td>Password </td> <td><input type="password" name="password" /></td> </tr> <tr> <td><input type="submit" name="login" value="Login" /></td> </tr> <tr> <td><a href="<?=$siteurl?>/register.php">Register</a></td> </tr> </table> </fieldset></form><?php}else{ //Declare some variables $email = secure($_POST['email']); $password = secure($_POST['password']); //Check if the form is filled out if (!$email || !$password) { echo 'Please fill out the form completely'; echo '<a href="'. $siteurl .'/login.php">Go Back</a>'; } else { $user = mysql_query("SELECT * FROM `users` WHERE email = '$email'"); if (! mysql_num_rows($user)) { echo 'That user doe not exist'; } else { //Encrypt the password $encpass = sha1($password . $salt); //Find the user $superquery = mysql_query("SELECT * FROM `users` WHERE email = '$email' AND password = '$encpass'"); if (mysql_num_rows($superquery) == 1) { //If the user is found, set the cookies setcookie("username", $email, 0); setcookie("password", $encpass, 0); setcookie("is_logged_in", true, 0); //send the user to the home page header("Location: " . $siteurl . "members.php"); } else { echo 'Password was incorrect. Please try again.'; } } }}ob_flush();?>() what am i doing wrong? What I have been attempting to do with no luck is utilize <?php echo $row_DetailRS1['NSN']; ?> as a hyperlink. The Hyperlink will point to another website http://www.logisticsinformationservice.dla.mil/webflis/pub/pub_search.aspx?niin=+++++++++++++ The 13 + signs would be populated with the 13 digit that is returned from <?php $info=$row_DetailRS1['NSN']; ?> Below is the complete code as it stands how. Any assistance with making this work is greatly appreciated. <A HERF="http://www.logisticsinformationservice.dla.mil/webflis/pub/pub_search.aspx?niin=<?php $info=$row_DetailRS1['NSN']; ?>"><?php echo $row_DetailRS1['NSN']; ?></A> One additional question. If I want a new page to open when the hyperlink is clicked would I add &newpage=1 to the end of the URL? Well I have a script that executes a scan on a system set to run infinitely, and I need it to echo out a message each time it loops through, but I don't want it to echo out the message with the next loop message below it, and the next one below that etc... I've tried using the flush(); function and been messing around with that with no luck. For security reasons I don't want to release any of the processing code, but here is the basic construction of the script: <?PHP ***PROCESSING AND SCAN CODE*** ***PROCESSING AND SCAN CODE*** ***PROCESSING AND SCAN CODE*** ***PROCESSING AND SCAN CODE*** $RepeatIt = -1; for($g=1; $g!=$RepeatIt+1; $g++) { ***PROCESSING AND SCAN CODE*** ***PROCESSING AND SCAN CODE*** ***PROCESSING AND SCAN CODE*** ***PROCESSING AND SCAN CODE*** $ScanMessage = ":.:.: SCANNING THE HITLIST FOR MOBSTER: ".$MobName." (SCAN #$g) :.:.:"."<br/><br/>"; echo $ScanMessage; ***PROCESSING AND SCAN CODE*** ***PROCESSING AND SCAN CODE*** ***PROCESSING AND SCAN CODE*** ***PROCESSING AND SCAN CODE*** } ?> At the moment it's returning: :.:.: SCANNING THE HITLIST FOR MOBSTER: DEUS EX DESTROYER (SCAN #1) :.:.: :.:.: SCANNING THE HITLIST FOR MOBSTER: DEUS EX DESTROYER (SCAN #2) :.:.: :.:.: SCANNING THE HITLIST FOR MOBSTER: DEUS EX DESTROYER (SCAN #3) :.:.: :.:.: SCANNING THE HITLIST FOR MOBSTER: DEUS EX DESTROYER (SCAN #4) :.:.: So what I want it to do is just delete the scanning message and replace it with the next scan message so while running this script you would see just the number increment on the same line. Any suggestions? Thanks.

I'm working by a magazine which should teach you exactly how to do this using PHP, but I've had a bunch of problems with the code they use and I don't really know what's going on. Anyway, this looks really simple and basically what it does is allows you to post a comment on a book, then returns you to the book's page. Problem is, I'm getting the Header may not contain more than a single header, new line detected. error and I can't figure out why. I've tried researching into the matter but all the cases I found had to do with returning to an url, which is not my case. Anyway, here's the snippet of code: The form: Code: [Select] <div style="width:400px; border:1px solid #ffffff; background-color:#F9F1E7; padding:5px"> <b>Adauga opinia ta:</b> <hr size="1"> <form action="adauga_comentariu.php" method="POST"> Nume: <input type="text" name="nume_utilizator"><br><br> Email: <input type="text" name="adresa_email"><br><br> Comentariu: <br> <textarea name="comentariu" cols="45"></textarea><br><br> <input type="hidden" name="id_carte" value="<?=id_carte?>"> <center><input type="submit" value="Adauga"</center> </form> </div> The script adaugare_comentariu.php: Code: [Select] <?php ob_start(); include("conectare.php"); $numeFaraTags=strip_tags($_POST['nume_utilizator']); $emailFaraTags=strip_tags($_POST['adresa_email']); $comentariuFaraTags=strip_tags($_POST['comentariu']); $sql="insert into comentarii (id_carte, nume_utilizator, adresa_email, comentariu) values(".$_POST['id_carte'].", '".$numeFaraTags."','".$emailFaraTags."','".$comentariuFaraTags."')"; mysql_query($sql); $inapoi="carte.php?id_carte=".$_POST['id_carte']; header("location:urldecode($inapoi)"); ob_end_flush(); ?> conectare.php connects to the mysql database. $inapoi is the variable which returns the user to carte.php (the book he posted a comment on), where id_carte is the book's unique id. I'm getting Header may not contain more than a single header, new line detected on line ten, which is the header line. Can anyone help me? I've been stumped on this for a few days now and I've just let it pass and started working on other bits, but it's bugging me too much and I'd like to fix it.

When it gets the characterIDList values if there is a value for that field it needs to take that value then explode it and get the ID and characterName of each of the values so say the value inside of characterIDList was 2,3 then for each of those values it would find the characterName and ID of the value and be able to put each of them as a LI inside the UL. I was hoping I could have the charactersQuery separate because I use it for the dropdown. Code: [Select] $newsQuery = " SELECT news.categoryID, news.newsTitle, news.newsPicture, news.content, news.characterIDList FROM news LEFT JOIN categories ON news.categoryID = categories.ID WHERE news.ID = '" . $newsID .
