php undefined function error

Hi, just created a php site using siteassitpro, but when I test pages on my remote server they are not displaying as they should. Problem seems to be with the line which references the menu php code for the page: <?php virtual("/CSSMenuWriter/cssmw_home/menu.php"); ?>

On the server in place of a navigation menu in the page I get the error message:

Fatal error: Call to undefined function virtual() in E:\domains\b\buytilesbypost.co.uk\user\htdocs\index.php on line 66

I know a little VB / ASP but I'm new to php - what am I missing?

Try changing:

<?php virtual("/CSSMenuWriter/cssmw_home/menu.php"); ?>

to:

<?php require_once("/CSSMenuWriter/cssmw_home/menu.php"); ?>

Hi - thanks for posting, tried that but got error messages:

Warning: require_once(/CSSMenuWriter/cssmw_home/menu.php) [function.require-once]: failed to open stream: No such file or directory in E:\domains\b\buytilesbypost.co.uk\user\htdocs\index.php on line 66

Fatal error: require_once() [function.require]: Failed opening required '/CSSMenuWriter/cssmw_home/menu.php' (include_path='.;C:\php5\pear') in E:\domains\b\buytilesbypost.co.uk\user\htdocs\index.php on line 6

This error message is saying tha the menu.php file cannot be found in its expected location (CSSMenuWriter/cssmw_home/menu.php). Check that the file is there to be found. I see you are rebuilding your site from .asp to php - if you are setting off converting the original php files, make sure that you haven't got a menu.asp file instead of the menu.php version (your remote site has CSSMenuWriter/cssmw_home/menu.asp).

Hi again Neilo

Using the same connection script etc (in Dreamweaver) to the remote server, I built the same site first in html, then in php and then in asp - backing up and moving the previous versions each time. You were looking at the contents of the asp version, which came after the problematic php version!

I agree that the message is saying it can not find the file in question (menu.php) which contains the php code to be "included" in index.php which is the "calling" file. The asp version "finds" menu.asp without any problem but the php version seems to get lost ...

My guess is it has something to do with the way the path is interpreted or concatenated or something in the php version, but as I'm not sure how this is done I don't know what to do to fix it.

the require once line should not include the leading forward slash:
<?php require_once("CSSMenuWriter/cssmw_home/menu.php"); ?>

in your site definition, there is a settings on the local info tab for "Create Links relative To", change this setting to "Document" instead of using "Site" so that Dreamweaver will create the include paths using the require_once() function instead of the virtual() function.

Thanks Jason, that worked for the "top level" pages - but those in sub-directories on the site just generate a simailar error message as before:


Warning: require_once(CSSMenuWriter/cssmw_content/menu.php) [function.require-once]: failed to open stream: No such file or directory in E:\domains\b\buytilesbypost.co.uk\user\htdocs\tiles\bathrooms\ceramic2.php on line 98

Fatal error: require_once() [function.require]: Failed opening required 'CSSMenuWriter/cssmw_content/menu.php' (include_path='.;C:\php5\pear') in E:\domains\b\buytilesbypost.co.uk\user\htdocs\tiles\bathrooms\ceramic2.php on line 98


... so any pages on th3e same level as "tiles" are found ok, but anything lower isn't. All the pages other than index.php are generated via a Dreamweaver template.

the path to the CSSMenuWriter/cssmw_content/menu.php file is relative to the document location.

the menu file will be at the root of the site so for a documet in a sub directory, you will need to modify the path.

for:
\tiles\bathrooms\ceramic2.php the path needs to go down 2 directories to the site root, then look for the CSSMenuWriter/cssmw_content/menu.php file:


<?php require_once("../../CSSMenuWriter/cssmw_content/menu.php"); ?>


like i said before, if you change the Create Links relative to option to document, then recreate the site using Site Assist, the pages will be created with the correct paths.

It's grand when something works ... I had forgotten to recreate the site using SiteAssist Pro!

Thanks for your help.

you're welcome.
