Warning message when including categories

  • I wanted to make two groups of sub-categories which are under the same parent, which works, but this warning shows up:

    Warning: Invalid argument supplied for foreach() in /htdocs/public/www/wp/wp-content/plugins/hierarchical-pages/hierpage.php on line 340

    How to solve?
    Or is there another way to show two separate groups of category under the same root?

    Hmm… as a test, could you please change two lines above the ‘foreach’ (should be line 338) from this:

    if ( $cats ) {

    to this:

    if ( !empty($cats) ) {

    and see whether that solves the problem?

    Parse error: syntax error, unexpected T_VARIABLE, expecting ‘(‘ in /htdocs/public/www/wp/wp-content/plugins/hierarchical-pages/hierpage.php on line 329

    It keeps displaying the warning:

    Warning: Invalid argument supplied for foreach() in /htdocs/public/www/wp/wp-content/plugins/hierarchical-pages/hierpage.php on line 346

    But only when I include the IDs, if I exclude it works. But I want to show only the children of the current categories, so it will be easier to include only the ids i want…

    I am experiencing the same problem. I have a main parent category with 8 child categories… and then those 8 child categories have “children”. It is displaying one of the child categories correctly but the children of the other child categories are not showing.

    I am also using the ‘include’ functionality and getting the following error….

    Warning: Invalid argument supplied for foreach() in /var/www/vhosts/dev.superboat.com/httpdocs/wp-content/plugins/hierarchical-pages/hierpage.php on line 115

    This plugin is exactly what I need if I can get it working properly… Thanks for creating!

    See example of error message from statement above…
