Fatal Error: cannot redeclare function

[Peter Troeger]

Hello

My last problem after upgrading to PW 3 was just solves and already do I have a new one :/

My site doesn't load corrctly and I get the error

Fatal error: Cannot redeclare stripTags() (previously declared in /site/assets/cache/FileCompiler/site/templates/_functions.inc:24) in /site/templates/_functions.inc on line 32

I looks almost like it's loading the functions file twice. Once the one in my template folder and once the one in the cache folder.
I tried deleting all folder in cache und deleting wire completely and reuploading it.

I still get the same error.

Anyone any hints for me?

Thanks a lot!
Peter

I'm only new to this too, but at a total guess:

1) Does this happen when you turn caching off and load the site?

2) Is 'stripTags()' a built in function (part of $sanitizer) and you're redefining it in your functions file?

3) Is the functions file only included once, and not somewhere else as well in another template? If '_init.php' (or whatever you've called it) is appended to your site, the functions within your '_functions.inc' file will already be available to all your other templates.

// _init.php

// Include shared functions
include_once("./_func.php"); 

4) What happens if you remove 'stripTags()' from your '_functions.inc' and then try and call this function in another template i.e. in home.php? Does the function still work?

I might be well off track but I'm sure the more experienced members will have a better idea. However, these are the avenues I'd try if you haven't already.

Hi Sam,

thanks for your good thoughts

1)  This happend after my upgrade from PW 2.7 to PW 3. I cleared the cache completely. Not sure if I can turn off the cache now. Is there some code i can add?

2)  and 4) when I delete stripTags, it just gives me an error that the next function in _functions.inc is redefined.

3) Functions is ony required_once in the init.inc. When I remove it from there I get an error because of undefined functions that can't be called

I don't understand why this worked in PW 2.7 but not in PW 3. But it kind of looks like a cache problem. But I deleted all cache files and they are rpopulated when I open the website.

Try to disable cache for the template(s): setup > templates > cache

(at least for a temporary workaround if it's a live site)

Perhaps checking if pw namespaces are at the top of your files might be another fix (that was introduced with pw 3).

The error disappeared with the namespaces, but now my site doesn't display correctly (no header and footer and no styling etc.).

I'll have to take a closer look next week and try again. Thanks for the help for now. I'll report back next week

I know you're going to wait awhile, but I'm only just back from work and have been thinking about this. Considering adding a namespace fixed your issue, perhaps it's also something to do with the compiler settings in:

Admin > Setup > Templates > Edit Template: "template-name")... in the 'Files' tab.

I had a different problem with this myself and had to choose 'Auto (compile when file has no namespace)'. Worth a look anyway.
