Hi peeps,
 
      I have this code here in a function.php file.
 
$row = mysqli_fetch_array(mysqli_query($con,"SELECT * FROM releases"));
$GLOBALS ['releaseids']=$row['id']; global $releaseids;
 
I then try & use this within a function
 
function postcontainer(){
global $releaseids;
foreach ($releaseids as $releaseid){
echo "this is the id";}
}}
 
 
Every time however, I keep getting 
 
 Invalid argument supplied for foreach() in...
 
This still applies too if it isn't put inside or outside of a function.
 
Very grateful

Okay, don't even bother trying to do it that way.

 

Pass the values to the function. Plus, a function shouldn't really echo anything, it should just return the data. You don't need a function to do what you're trying to do, just the foreach() wherever your values are already defined.

 

Stop using global completely. Forget that word exists.
