WU-graphs php header problem.

I guess this problem is aimed at the PHP gurus

.

I have WU-graphs running as "stand alone" here:http://www.nightingaleweather.co.uk/wugraphs.php.

But when I use include on a page where I want it I get this:

Quote:

Warning: Cannot modify header information - headers already sent by (output started at /home/*********/public_html/template101.php:15) in /home/night239/public_html/wugraphs.php on line 35

Warning: Cannot modify header information - headers already sent by (output started at /home/*********/public_html/template101.php:15) in /home/night239/public_html/wugraphs.php on line 44

Warning: Cannot modify header information - headers already sent by (output started at /home/*********/public_html/template101.php:15) in /home/night239/public_html/wugraphs.php on line 45

Warning: Cannot modify header information - headers already sent by (output started at /home/*********/public_html/template101.php:15) in /home/night239/public_html/wugraphs.php on line 46

Page is here:http://www.nightingaleweather.co.uk/template101.php

It produces one of these every time there is "<?php".

For example, the one above is line 15 in template101.php which is include cumulustags. If I delete this from template101 it does the same on the next "<?php" which is header and so on right down to the footer and including itself :roll:

Quote:

<?php
include("wugraphs.php");
?>

I also placed it on an empty page and the same result: http://www.nightingaleweather.co.uk/template105.php

Quote:

Warning: Cannot modify header information - headers already sent by (output started at /home/*******/public_html/template105.php:11) in /home/night239/public_html/wugraphs.php on line 35

The line 11 here where it fails is its own <?php.

Quote:

<?php
include("wugraphs.php");
?>

So what is going on?

Without actually seeing both your template code and / or delving into the WU-Graphs code, I would hazard the guess that there is an 'include' or 'stand-alone' option.

You would seem to have the stand-alone option but trying to use it as an include. - I think

Whenever I get

Warning: Cannot modify header information - headers already sent

errors in php they are usually caused by characters getting through to the browser before php sends its headers. This is often due to spurious spaces before an opening <?php tag in one of your includes.

Hope this helps.

I was looking on your website and it looks like you resolved your problem.
I have been trying to do something similar based on Jacque's Sunny Weather template.
So, to point me in the right direction, as I'm trying to get to grips with PHP in a simple form, do you just "call" the wugraphs.php page from within another PHP page using the include statement you've detailed above?
And what was the final reason for the problem?
Hope you can help?

All I've done to get it working is to "include" as above and then simply edit out each line that produces an error. I think there are about 10 lines on the WUGraphs page and 3 in the config. If you simply upload it to your site and go to the page you "include", the errors will be listed with the line number you need to edit out. Better still use XAMPP.

I shall be revisiting this page soon and I am told the best way is not to include but to basicly cut and paste the wugraphs to the page where you want them and play with it from there.

Hope this helps.

See my earlier post - there is a 'flag' to set to say you are using it as include, otherwise it tries to create a stand-alone page with its own headers in the page you've already got headers for !

This was already set to "true" for include mode and did not resolve my problems. The only way for me to get this to work was "//".

Just in case I got it wrong before, just tried again with the same problem. if you want to try "include = true" I think it's line 363 in WUGsettings.

Thanks Duke and Beteljuice, won't get to try this out until next week sometime, but thanks for the advice.
I'll see how it pans out and come back for more guidance if needs be.
