Invalid argument supplied for foreach() in

Question

Ok So I am lost this code snippit is from a word-press plug in I downloaded. I emailed the creator but no response. The sad thing is it was just updated a week ago so not sure what they did to it. I had it working and suddenly now getting this error when i try and upload through it.

 // Add the known elements css.
    foreach ($this->elements_options as $key => $value) {
        if(strpos($key, 'important') || !$value)
            continue;

This is the line that wordpress is saying the error is on. To me it looks right But php is calling it invalid.

Any help would be appreciated

This error simply mean that the variable `$this->elements_options` is not an array or a `stdObject` so it cannot be iterate through using a foreach. You should place a `die(var_dump($this->elements_options));` before the foreach to check what is in the variable. Maybe post it here so we can help you a little bit more. — Nicolas, Feb 13 '17 at 16:55
I actually got it fixed turns out it is a wordpress issue that will be fixed in the next version I had to download another plug in to counter act the core issues — Kirk Sturgulewski, Feb 13 '17 at 17:11

You are not using strpos() function correctly.

i.e, if(strpos($key, 'important') || !$value) // Incorrect way

strpos() function in this condition returns the numeric position (or value). But you are looking for boolean true/false. so you need to explicitly check.

Also, you might want to change your condition to something like :

if(strpos($key, 'important') !== false || !$value)
