Invalid argument supplied for foreach()

[zszalma]

Phoca Gallery version 2.8.0, Joomla 1.5.23 Virtuemart 1.1.7

I created menu link as described in https://www.phoca.cz/documents/14-phoca- ... gin/97-faq
Activated Phoca Gallery Plugin.

Created category with id=1, and upload 3 photos in this category.

In an article in Joomla 1.5 write this line:

Code: Select all

{phocagallery view=categories|imagecategories=1|imagecategoriessize=1|hidecategories=1}

The same line appears in frontend instead of images.


Got Warning message:
Warning: Invalid argument supplied for foreach() in E:\FEJL\www\kutyaseta_88\htdocs\plugins\content\phocagallery.php on line 740

This line is:

Code: Select all

foreach ($data_outcome_array as $category)

var_dump($data_outcome_array) says:
string '' (length=0)

I have debugging turned on with PHP XDEBUG plugin.
Debug output is:

Code: Select all

Any help would welcome. Many thanks.

Hi, enable debug mode (in global configuration of Joomla!) which then says more about the problem in the database.
