Sharp Context ​

Sharp provide a way to grab some request context values in the application code.

Ask for context ​

The class handling the context is Code16\Sharp\Http\Context\CurrentSharpRequest, which is a singleton. So at any point in the request, you can get it via:

app(Code16\Sharp\Http\Context\CurrentSharpRequest::class);

app(Code16\Sharp\Http\Context\CurrentSharpRequest::class);

or with the global helper:

currentSharpRequest();

currentSharpRequest();

Here's a quick example:

class MyForm extends SharpForm
{
    // [...]
    
    function buildFormFields()
    {
        $this->addField(
            SharpFormTextField::make("name")
                ->setReadOnly(currentSharpRequest()->isUpdate())
        );
    }
}

class MyForm extends SharpForm
{
    // [...]
    
    function buildFormFields()
    {
        $this->addField(
            SharpFormTextField::make("name")
                ->setReadOnly(currentSharpRequest()->isUpdate())
        );
    }
}

The context is often useful in a Form situation to display or hide fields depending on the instance status (creation, update), or in a Validator to add an ID exception in a "unique" rule.
