I cant set a cookie because the header has already been sent? I dont get it, and the code is outside the head tags, on top of my page.

 

Help?

I believe there is a sticky about this: http://www.phpfreaks.com/forums/index.php/topic,37442.0.html

My guess is that one of the meta refresh things is being echo'd before you attempt to set the cookie... thus headers sent.

[phpSensei]

The Script is on top of everything, meaning line 1, so the only META comes after the setcookie.

[dbo]

If any of your queries fail it will send headers. That may or may not be the case... I dunno. But what I do know is that computers only do what you tell them (despite what we sometimes think) somewhere there is a problem with your script.... not php lying

[phpSensei]

lol, Okay, I will take a better look at it, but keep in my mind, the data is sent to the database and no query fails at all.

Unless im being completely blind, you've not included the part of the code that sets the cookie. Therefore, we can't suggest where the output is coming from.

 

Also, the error message will tell you what line the header was already sent by. It would be useful to have that information. Help us help you.

If the script is online do you have a link I can view it at?

[phpSensei]

Its not online, but I can uploaded to my current free host...

[dbo]

please do so if you dont care

[phpSensei]

So sorry man, It Keeps showing up blank because the stupid host does not support php.

 

How ridiculious....

 

I will try it on other servers, then update you about it.

[phpSensei]

I dont know if this link will work, but hope for the best...

It did a whole lot of nothing... no errors... no output... nothing. So that might mean it worked?

[phpSensei]

Well, It was a blank page right? I mean, It runs the script only when you post a new topic in the forum.
