session_start error

gribble · #1 Sep 17th, 2007, 07:07

when I test this script I get the following error -

"Warning: session_start(): Cannot send session cache limiter - headers already sent (output started at /hsphere/local/home/icmwebs/inkukustop.co.za/form.php:3) in /hsphere/local/home/icmwebs/inkukustop.co.za/form.php on line 3"

I have checked for extra spaces and made sure the php is before the html tag.

Here is the script:

<body bgcolor="yellow">
<div align="center">
<?php session_start();
if( isset($_POST['submit'])) {
if( $_SESSION['security_code'] == $_POST['security_code'] && !empty($_SESSION['security_code'] ) ) {
// Insert you code for processing the form here, e.g emailing the submission, entering it into a database.
echo 'Thank you. Your message said "'.$_POST['message'].'"';
unset($_SESSION['security_code']);
} else {
// Insert your code for showing an error message here
echo 'Sorry, you have provided an invalid security code';
}
} else {
?>
<form action="form.php" method="post">
<label for="name">Name: </label><input type="text" name="name" id="name"><br>
<label for="email">Email: </label><input type="text" name="email" id="email"><br>
<label for="message">Message: </label><textarea rows="5" cols="30" name="message" id="message"></textarea><br>
<img src="CaptchaSecurityImages.php?width=100&height=40 &characters=5"><br>
<label for="security_code">Security Code: </label><input id="security_code" name="security_code" type="text"><br>
<input type="submit" name="submit" value="Submit">
</form><?php
}
?></div>
</body>

any ideas please?

The session start must be the very first thing on the page because it is part of the header. When you output something onto the page the headers will have been sent and a session cannot be started.

So you should do this to make it work:

PHP: Select all


<?php session_start(); ?>
 
<body bgcolor="yellow">
<div align="center">
<?php
if( isset($_POST['submit'])) {
.....
...
?>

Oooh! a testimonial on the front page...my 15 seconds of fame...

Your solutions worked a treat but I am having trouble getting the message field to appear in the email reply. I just get the email address and the name.

here is the amended code:

<?php session_start();
if( isset($_POST['submit'])) {
if( $_SESSION['security_code'] == $_POST['security_code'] && !empty($_SESSION['security_code'] ) ) {
mail( "emotion@inspire.net.nz", "Website Feedback", $name, $email, $message );
echo 'Thank you for your enquiry. Will contact you shortly';
unset($_SESSION['security_code']);
} else {
// Insert your code for showing an error message here
echo 'Sorry, you have provided an invalid security code';
}
} else {
?>
<form action="form.php" method="post">
<label for="name">Name: </label><input type="text" name="name" id="name"><br>
<label for="email">Email: </label><input type="text" name="email" id="email"><br>
<label for="message">Message: </label><textarea rows="5" cols="30" name="message" id="message"></textarea><br>
<img src="CaptchaSecurityImages.php?width=100&height=40 &characters=5"><br>
<label for="security_code">Security Code: </label><input id="security_code" name="security_code" type="text"><br>
<input type="submit" name="submit" value="Submit">
</form>
<?php
}
?>

Additionally, is it possible to add a background color and css styling to the echo messages?

I don't know where the $name, $email, and $message variables get set, but like this is should work:

PHP: Select all


<?php session_start();
if( isset($_POST['submit'])) {
    if( $_SESSION['security_code'] == $_POST['security_code'] && !empty($_SESSION['security_code'] ) ) {
        mail( "emotion@inspire.net.nz", "Website Feedback", $_POST['name'], $_POST['email'], $_POST['message'] );
        echo 'Thank you for your enquiry. Will contact you shortly';
        unset($_SESSION['security_code']);
    } else {
        // Insert your code for showing an error message here
        echo 'Sorry, you have provided an invalid security code';
    }
} else {
?>
<form action="form.php" method="post">
<label for="name">Name: </label><input type="text" name="name" id="name"><br>
<label for="email">Email: </label><input type="text" name="email" id="email"><br>
<label for="message">Message: </label><textarea rows="5" cols="30" name="message" id="message"></textarea><br>
<img src="CaptchaSecurityImages.php?width=100&height=40 &characters=5"><br>
<label for="security_code">Security Code: </label><input id="security_code" name="security_code" type="text"><br>
<input type="submit" name="submit" value="Submit">
</form>
<?php
}
?>
