Thanks,

Hi There,

I've implemented your script in a WordPress theme that I'm building locally.

Instead of using it to change the background for the header, I've used it to change the background image I'm using for the dates of my blog posts.

It works like exactly like it's supposed to, but now I'm wondering if there's any way to get it to pick a different image for every post? So, in addition to changing on each page refresh, each post would have a different background image behind the date?

Thoughts?

Thanks a bunch for the code and your help!

Dionne

Hi,

Thanks for ur help. However, I talked to my hosting company and they have also set the permission but I'm still not able to get rid of the warning. They said there may be some problem with your coding, please check that.

Now I'm stuck in the middle. Pls help if it's possible for you.

Any help will be greatly appreciated.

Thanks again…

Hi, thanks for the detailed report. Everything looks to be set up correctly as far as paths go. The problem is likely to be a permissions issue on the production server. As it's a Windows server I can't offer much direct assistance. This post on PHP.net may offer some guidance http://www.php.net/manual/en/function.opendir.php#79685

Thank you so much for your quick response. I really appreciate it.

After adding this line
die($path);

when I navigate to the url below:
http://woodlightproductions.com/login/dynamic_css.php

it gives me this result:
/login/images/random-images/

Here is the link I am trying to set the background image
http://woodlightproductions.com/login/login.php

And the images are exactly in the below destination folder of my production server.

httpdocs/login/images/random-images

And the dynamic_css.php, styles.css and login.php all these files are in login folder.

Please suggest.

Hi Pradeep, it looks very much like you are experiencing path issues on the production server. First step is to verify that the path you are setting in the dynamic_css.php file is being converted to a correct path.

You can test this by echoing out the $path variable in the dynamic_css.php file by adding:

die($path);

directly after the line that reads:

$path = $_SERVER['DOCUMENT_ROOT'] . $imgFolder;

If the path is not correct adjust it until it is. If you still experience issues send me the actual URL so that I can debug from my end.

Just adding few more warnings..I get from the above code

when I navigate to dynamic_css.php in the url I get the below warning messages:
http://domainname.com/login/dynamic_css.php

Warning: opendir(/login/images/random-images/) [function.opendir]: failed to open dir: No error in C:\inetpub\vhosts\domainname.com\httpdocs\login\dynamic_css.php on line 47

Warning: readdir(): supplied argument is not a valid Directory resource in C:\inetpub\vhosts\domainname.com\httpdocs\login\dynamic_css.php on line 50

Warning: closedir(): supplied argument is not a valid Directory resource in C:\inetpub\vhosts\domainname.com\httpdocs\login\dynamic_css.php on line 59

But when I navigate to the same dynamic_css.php file on my localhost it's working fine and giving me the below result.

#body { background-image: url('/login/images/random-images/bg_img5.jpg'); }

Expecting an early response.
Thanks

Hi,

I tried your script. It works fine on my local host (IIS). But when I upload it to the web server it doesn't load the background images.

Here is the detail
Windows Web Server.
root folder is: httpdocs

Under root folder I have created a folder login.

All my php files are inside login folder.

File I am trying to get it work with the background is login.php
Inside 'login.php' file

@import url("/login/dynamic_css.php");

// table and rest of the stuff are here..

Inside dynamic_css.php
———————————-
$imgFolder = "/login/images/random-images/"; // all my bg images are in random-images folder. file size around 2 MB each
$element = "body";

Inside styles.css
———————–

body {
// no default background is set..
}

So as per above structure it works absolutely fine at the below link of my localhost

http://localhost/login/login.php

So all the files are inside login folder and login folder is lying at the root folder wwwroot of my localhost and working fine.

But when I uploaded the same login folder to my web server it's not working.

I have tried with the following options in dynamic_css.php file

$imgFolder = "http://domainname.com/login/images/random-images/"; // it also doesn't work

$imgFolder = "http://www.domainname.com/login/images/random-images/"; // it also doesn't work

$imgFolder = "/login/images/random-images/"; // it also doesn't work

$imgFolder = "../login/images/random-images/"; // it also doesn't work

with the following options in login.php

@import url("http://www.domainname.com/login/dynamic_css.php"); //doesn't work

@import url("http://domainname.com/login/dynamic_css.php"); // doesn't work

@import url("/login/dynamic_css.php"); // doesn't work

A suggestion will be highly appreciated.

Thanks,
