			0 ignored issues – show Bug introduced 2020-05-18 05:26 UTC by Report Bug Copy Issue Report The method `getOriginalModel` does only exist in `Encore\Admin\Grid\Model`, but not in `Illuminate\Database\Eloquent\Builder`. It seems like the method you are trying to call exists only in some of the possible types. Let’s take a look at an example: class A { public function foo() { } } class B extends A { public function bar() { } } /** * @param A\|B $x / function someFunction($x) { $x->foo(); // This call is fine as the method exists in A and B. $x->bar(); // This method only exists in B and might cause an error. } Available Fixes Add an additional type-check: /* * @param A\|B $x / function someFunction($x) { $x->foo(); if ($x instanceof B) { $x->bar(); } } Only allow a single type to be passed if the variable comes from a parameter: function someFunction(B $x) { /* ... */ } Loading history...

			0 ignored issues – show Bug introduced 2020-05-18 05:26 UTC by Report Bug Copy Issue Report The variable `$data` does not seem to be defined for all execution paths leading up to this point. If you define a variable conditionally, it can happen that it is not defined for all execution paths. Let’s take a look at an example: function myFunction($a) { switch ($a) { case 'foo': $x = 1; break; case 'bar': $x = 2; break; } // $x is potentially undefined here. echo $x; } In the above example, the variable `$x` is defined if you pass “foo” or “bar” as argument for `$a`. However, since the `switch` statement has no default case statement, if you pass any other value, the variable `$x` would be undefined. Available Fixes Check for existence of the variable explicitly: function myFunction($a) { switch ($a) { case 'foo': $x = 1; break; case 'bar': $x = 2; break; } if (isset($x)) { // Make sure it's always set. echo $x; } } Define a default value for the variable: function myFunction($a) { $x = ''; // Set a default which gets overridden for certain paths. switch ($a) { case 'foo': $x = 1; break; case 'bar': $x = 2; break; } echo $x; } Add a value for the missing path: function myFunction($a) { switch ($a) { case 'foo': $x = 1; break; case 'bar': $x = 2; break; // We add support for the missing case. default: $x = ''; break; } echo $x; } Loading history...
