[My session variable disappears :(]

Sometimes I had to use

if(!empty($_SESSION['session_name'])) {
    //code here;
}

 

for some reason sometimes $_SESSION would be set, and would trigger a false positive. So try that out and hopefully it might help you out.

 

Tried that, didn't work

[My session variable disappears :(]

That didn't help

 

I added session_save_path("mysessions") right before session_start() in header.php. Afterwards, I can see the session files being created in the "mysessions" directory on the webserver, but the session variable still doesn't exist when I need it in go.php

 

Any other ideas on what might be going wrong?

 

Thanks again,

Mads

Sounds like a good idea, I'll try to add session_save_path() call and see what happens.

 

Thanks a lot for the help.

[My session variable disappears :(]

I have no idea why, but sometimes my session variable disappears. After having stared at it for two days, I guess it's time to cry for help...

 

This is how I set the variable and later try to use it again:

 

1) I'm creating a session in header.php (a file that is loaded everytime a webpage is displayed):

session_start();

...

$_SESSION['displaymode'] = "abe";

 

2) I'm using the variable in go.php (which does not load header.php when it is displayed):

session_start();

...

if(isset($_SESSION['displaymode']))

{

    $displaymode = $_SESSION['displaymode'];

}

 

Can anyone see why my session variable disappears? isset() returns false approx. 50% of the time and I have absolutely no idea why

 

Thanks a lot,

Mads

It also doesn't work on my machine at home, but I have discovered something: The script works perfectly if I put it in a seperate file and upload it.

Both Daniel0's (http://www.horseornot.com/abe1.php) and my script (http://www.horseornot.com/abe2.php) work if I put them in seperate files (although Daniel0's script look far better when it's placed in a seperate file...).

Guess the conclusion is that Wordpress affect how my textarea behaves, so I will move to the wordpress forum and annoy people there  :P

Thank you for all your help.

But this is just form stuff - it happens long before we attempt to do any mail stuff.

Same thing in Explorer... I will try on my computer at home later today.

Thanks for your help.

Yes, it is running your script right now (http://www.horseornot.com/tell-a-friend/)

I noticed that you haven't got any line breaks in your screenshots. Does it still work if you add some line breaks?

Maybe it's worth mentioning that my script runs inside a page created by Wordpress.

Still no luck - sad to report that the long piece of code doesn't improve things.

I have moved some of the things outside the textarea. It looks like "html_entity_decode($message_text);" do what it is supposed to do, so the problem is caused by the textarea.

Still doesn't work :(

<textarea name="message_text" rows="10" cols="45"><?php echo html_entity_decode($message_text); ?></textarea></p>

Didn't help :(
<textarea name="message_text" rows="10" cols="45"><?=html_entity_decode($message_text);?></textarea></p>

Thank you for your reply.

Works great for the text inputs, but the textarea behaves a little bit crazy. It shows the HTML tags when the page reloads...?

(Just forget to fill out one of the e-mail address fields in order to see the effect)

Aloha,

I have created a simple tell a friend form. If the user click send without filling out all of the required fields, I show an error message and the form once more. My problem is that the contents of the form get cleared when I reload the form :(

I would of course like to keep the contents, so the user doesn't get annoyed and leave my website without telling their friends. How do I keep the contents?

Here is the complete (sigh...) code for my form:
------------------------------------------------------------------------
Please fill out this form and click send.

<?php
unset($message_sendername);
unset($message_sender);
unset($message_recipient);
unset($message_subject);
unset($message_text);

  // Get the image text and title
  $message_sendername = $_POST["message_sendername"];
  $message_sender = $_POST["message_sender"];
  $message_recipient = $_POST["message_recipient"];
  $message_subject = $_POST["message_subject"];
  $message_text = $_POST["message_text"];

// Validation
if($_POST["action"] == "Send")
{
if(empty($message_sendername) == true || empty($message_sender) == true)
{
$error["message_sender"] = "Please write your own name or your own e-mail address.";
}

if(empty($message_recipient) == true)
{
$error["message_recipient"] = "Please write your friend's e-mail address.";
}

if(empty($error) == false)
{
unset($_POST["action"]);
}
}

if($_POST["action"] == "Send")
{
$headers  = "From: \"$message_sendername\"<$message_sender>\n";

// Send the e-mail
mail($message_recipient, $message_subject, $message_text, $headers);

print("<p>Your message has been sent to $message_recipient.<br/><br/><a href='/tell-a-friend'>Send another message</a></p>");
}
else
{
// Show errors - if any
if(is_array($error))
{
print("Something went wrong:<br/><font color='#FF0000'>");
while(list($key, $val) = each($error))
{
print("$val");
print("<br>\n");
}
print("</font>");
}
?>
