"Using $this when not in object context." Here's the fix.

The “Using $this when not in object context” error occurs because you are calling a non-static method from a static method.

To fix it, make your static method non-static and call it from an object.

How to fix “Using $this when not in object context”, step by step

Take this code and try to run it to see “Using $this when not in object context” for yourself.

class Foo {
    public static function bar() {
        $this->baz();
    }
 
    public function baz() {
    }
}
 
Foo::bar();

As you can see, we are trying to call baz(), which is a non-static method, from a static method.

As mentionned above, we need to:

1. Remove the static keyword from bar()’s declaration;
2. Create an instance of Foo and call bar() from there.

 class Foo {
-    public static function bar() { 
+    public function bar() { 
         $this->baz();
     }
  
     public function baz() {
     }
 }
  
-Foo::bar(); 
+$foo = new Foo; 
+$foo->bar();
