Fatal Error: Using $This When Not in Object Context

PHP Fatal error: Using $this when not in object context

In my index.php I'm loading maybe
foobarfunc() like this:

 foobar::foobarfunc();  // Wrong, it is not static method

but can also be

$foobar = new foobar;  // correct
$foobar->foobarfunc();

You can not invoke the method this way because it is not a static method.

foobar::foobarfunc();

You should instead use:

$foobar->foobarfunc();

If however, you have created a static method something like:

static $foo; // your top variable set as static

public static function foobarfunc() {
    return self::$foo;
}

then you can use this:

foobar::foobarfunc();

Using $this when not in object context in PHP

You are not inside instance of class to use $this. Try this, it will work

require_once 'models/Request.php';

$req = new Request;

if(isset($_POST['submit'])){
    $data = [
        'reqBy' => $_POST['reqBy'],
        'off' => $_POST['off'],
        'prob' => $_POST['prob']
    ];

    echo "<pre>";
      print_r($data);
    echo "</pre>";

    if($req->addRequest($data)){ //This is the line where it points the error
        echo 'Sucess';
    }else{
        echo 'Something';
    }
}
?>

Fatal Error: Using $this when not in object context

$this will not be available in a static function. You'll probably want to re-create $app within the static function:

static function store($key, $value)
{
    $app = base_url('application') . '/cache/';
    $key = sha1($key);
    $value = serialize($value);
    file_put_contents( $app . $key.'.cache', $value);
}

I'm not quite sure what you're trying to do in the grand context of your application, but you may not even need a static method in the first place.

PHP : Fatal error: Using $this when not in object context in

Here's the problem:

while($oLicence = cLicences::getAll($rLicences)) {

You're trying to access getAll method statically instead of calling it on an instance of the class (object). Therefore you have to object context in this method call, while you're using $this inside.

You should just change it to call method on object that you have already created anyway.:

while($oLicence = $cLicences->getAll($rLicences)) {

PHP - How to solve error using $this when not in object context ?

Your problem is connected with differences between class's methods/properties and object's.

1. If you define a property as static - you should access it through your class like classname/self/parent ::$property.
2. If not static - then inside static property like $this->propertie.

For example:

trait Example   
{
    protected static $var;
    protected $var2;
    private static function printSomething()
    {
        print self::$var;
    }
    private function doSomething()
    {
        print $this->var2;
    }
}
class NormalClass
{
    use Example;
    public function otherFunction()
    {
        self::printSomething();
        $this->doSomething();
    }
    public function setVar($string, $string2)
    {
        self::$var = $string;
        $this->var2 = $string2;
    }
}
$obj = new NormalClass();
$obj -> setVar('first', 'second');
$obj -> otherFunction();

Static function printSomething can't access not static propertie $var!
You should define them both not static, or both static.

Fatal error: Using $this when not in object context in E:\xampp\htdocs\

$role = userrole::get_premium_subscritpion(1);

I notice that you are trying to call a non-static function in a static way

You may either change the function to static or change the way you call this function

public static function get_premium_subscritpion {

or

$obj = new userrole();
$role = $obj->get_premium_subscritpion(1);

Fatal error: Using $this when not in object context in

Like the error says, you can't use $this outside of the class definition. To use $_db outside the class definition, first make it public instead of private:

public $_db

Then, use this code:

$authDb = new AuthDb();
$authDb->_db->prepare($query); // rest of code is the same

You have to understand what $this actually means. When used inside a class definition, $this is used to refer to an object of that class. So if you had a function foo inside AuthDB, and you needed to access $_db from within foo, you would use $this to tell PHP that you want the $_db from the same object that foo belongs to.
