Re: [Apc-aa-coders] Changes in AA Subversion and CVS - 2007/02/06

[Honza M. <hon...@ec...>]

Hello,

   Norbert Brazda pointed out, that there are some problems with current
SVN version of AA under PHP4.

   The Error looks like:

> Parse error*: parse error, unexpected T_OBJECT_OPERATOR in
> */www/htdocs/apc-aa/include/item.php3* on line *379

   and is caused by code:

return AA_Slices::getSlice($this->getSliceID())->getWidgetAjaxHtml($field=
_id, $this->getItemID(), $this->getAaValue($field_id));

   The problem is, that PHP4 do not allow to use function call as
object, so getSlice(..)->getWidgetAjaxHtml() causes problem. The
solution is to rewrite the code to:

$slice =3D AA_Slices::getSlice($this->getSliceID());
return $slice->getWidgetAjaxHtml($field_id, $this->getItemID(), $this->ge=
tAaValue($field_id));

   There is more than this one occurrence of this problem in SVN. I
didn't noticed the problem, since we are no longer use PHP4 (BTW,
current PHP5 works very well with eAccelerator - al least the versions
we are using). I hope there will not be more such problems, since I
still trying to make AA compatible with PHP4.

   Norbert is currently fixing the problems and he will commit the
changes to the SVN. Thanks Norbert!
