Fatal error: Cannot unset string offsets in vendor/smarty/smarty/libs/sysplugins/smarty_internal_compile_block.php on line 337 about smarty HOT 13 CLOSED

v3.1.21 does not have this bug, works fine.

from smarty.

You should probably add the (template or other) code that triggers this error.

from smarty.

Please provide example code

from smarty.

I can't reproduce the problem. Do you get it on all templates?

from smarty.

for the time being just in one, i'll provide the templates tomorrow

from smarty.

i can't seem to isolate this issue, it's produced by mail tamplate that is rendered using fetch() and before each render clearAllAssign() is issued. tried to reproduce it but currently i can't, it appears to happen only some times. I will try to find how to reproduce it all of the time.
Template:
https://gist.github.com/Gamesh/3cd1a0926227fdceee0e

from smarty.

The provided template does not contain any {bock}{/block} tags.
The compiler failed while compiling an inheritance template on {bock}{/block} tags.
Did you modify template files which caused a recompilation?

from smarty.

the provided template has one block tag

                                {block "mail_body"}
                                    {$message}
                                {/block}

or am i missing something ?

no, i didn't modify any files, i might have cleared the cached versions and templates_c folder

from smarty.

Sorry I did not see the {block} tag. Clearing the templates_c folder does explain the recompile. Can you show your template structure? Where did you include the failing template? Inside other block tags?

from smarty.

Even if the root cause of the error message is still unknown I added some extra check to avoid it.
The fix is now in dev-master

from smarty.

that just is the weird thing this template is not included as parent template anywhere. It is just used as standalone template and the block tags were there for future template extending. So even if some other templates change they should not cause this template to recompile as it remains the same and is not being extended or included anywhere, and has not changed for a long time.

from smarty.

It did recompile because you cleared templates_c .
Also now the error is clear to me. Caused by a standalone template with {block} tags.
For now either remove the {block} tags until next release or install dev-master.

from smarty.

ok, thanks for the fix. i've downgraded to smarty 3.1.21 for now, that was the last version that worked without errors with this template, i'll just wait for the next stable release
