Retrieving the identifier from a value within a Symfony controller

Question

Retrieving the identifier from a value within a Symfony controller

One thing I am looking to achieve is to retrieve an Id based on a folder number. Both the Id and folder number (which is unique) are located in the same controller.

I input the folder number from a text box and then need to direct the user to a /Id page.

My question is how should I approach this?

Do I create a method getIdFromFolderNumber() within my controller and then invoke this function in my JavaScript function? Or should I handle everything within a JavaScript function (I know I'll need a JS function as I plan to use AJAX for redirection and input value retrieval)?

I'm not looking for actual code here, just guidance on the approach I should take to understand how to do it. I've recently started work on a major project and, being a junior developer, I feel a bit overwhelmed.

Your assistance is greatly appreciated.

Answer №1

To achieve the desired outcome, there is no need for JavaScript. It simply involves setting up a basic form and redirection process.

Upon submitting your form to obtain the number:

$number = $form->get('number')->getData();

You can then use this number as criteria for your doctrine request:

$id = $yourEntityRepository->findBy(['number' => $number)])->getId();

With the ID in hand, you are now ready for the redirection:

return $this->redirectToRoute('entity_show', ['id' => $id]);

Was this the solution you were seeking?

Note: The variables $number and $id do not need to be stored; they were used here for clarity. You can directly substitute them with the appropriate requests where necessary.
