Can anyone correct the code please?
The problem part is in bold..if i dont use this part of the code, everything works fine..:mad:
 
I maybe wrong, but try initializing $postcat = array() before it is used. also replace
if( ! is_array( $postcat ) ) {

foreach ( $cp_categories as $b ) {

$postcat[] = $b->cat_ID;

}

}

with
if( ! is_array( $postcat ) ) {

foreach ( $cp_categories as $b ) {

$postcat = $b->cat_ID;

}

}

Edit: If that doesn't work, try to supress the warnings with a @ in front of the line. If the code is correct, it might still work
 
Insert <?php $postcat = array() ?> before the line where it is used.

Also
if( ! is_array( $postcat ) ) {

@foreach ( $cp_categories as $b ) {

$postcat = $b->cat_ID;

}

}

If you get warnings, and if your script does function properly, use the @ symbol before the function where it shows warning. For example if a warning is displayed before array_slice() in a particular line, just use @array_slice()
 
Tried..Still the same thing:(

BTW, i was searching and similar errors were cause because the array had value 0 or something..does that help?
 
If the array is null, then the functions array_slice() or foreach() won't work. That is because they need data in the array. try print_r(arrayname); to display the contents of the array in a readable form. And see if anything is displayed.
