Fatal error: Cannot declare class - Joomla 3.7

Fatal error: Cannot declare class - Joomla 3.7

2 years 6 months ago - 2 years 6 months ago #1553 by Søren Beck Jensen

Hi all,

We realize that Joomla 3.7 causes issues with components. We have already fixed Component Creator to work around this issue in Joomla so you can simply rebuild your component.

If you have made modifications to your component and can't just rebuild here is a solution to fix the issue manually.

If your component is called "com_example":

  1. Rename /administrator/com_example/helpers/example.php to exampleadmin.php
  2. Add the following string to the bottom of the file
    // Ensure custom fields compatibility
    class ExampleHelper extends ExampleHelpersExampleadmin {}
    Remember to rename "Example" with the name of your component.
  3. Perform a search and replace in the folder (and sub folders) /administrator/components/com_example/ Search for ExampleHelpersExample and replace with ExampleHelpersExampleadmin

It is important to ONLY perform the search and replace in the /administrator/com_example/ folder (and sub folders).

We are sorry for the inconvenience this Joomla issue may have caused you.

Do you have idea if this issue will remain or be fixed in upcoming 3.7.1 for example?

Hi Søren,

Can you please tell us which change in Joomla 3.7 caused this and any other compatibility break?

PS: I'd suggest to change the title of this page as the it causes to think for a moment as if something is broken here :)

H Soren,

What if I upgraded Joomla to 3.7 and the custom components are NOT showing that Fatal error?
I have many sites with JCC all upgraded to Joomla 3.7, but not seen this Fatal error yet.
Even while Error Reporting is set to Development.

And should you not rename that file in the view.html.php files?

protected function addToolbar() {
        require_once JPATH_COMPONENT . '/helpers/example.php';

to
  require_once JPATH_COMPONENT . '/helpers/exampleadmin.php';
And only change the classname once in exampleadmin.php from ExampleHelpersExample to ExampleHelpersExampleadmin

Can you explain that? Or am I using very old JCC code?

Regards,

Gosling

I was not getting that error, I renamed the helper file anyway (step 1),
now on step 2 there's a note that says "It is important to ONLY perform the search and replace in the /administrator/com_example/ folder" if I do that I'm not getting any search results, but if I do recursive search starting with that folder it returns several hits.
So, I just want to confirm the search is not recursive right ? Maybe that's the reason I'm not affected by this ?

Thanks,

Cesar
