What is it you're putting in the query string exactly? Are you talking about form submissions?

If you're submitting a form, you should be doing a post, in which case the data goes into the post body, not the query string.

Yea, i think that if you can provide more context then there may be insight to be gained.

Sorry, in the query string I am inputting a GUID of a multi-page form. Rather then using a auto increment I used a random string created with

openssl_random_pseudo_bytes('5') // Creates 10 character long string

So at each step of the multi-page form when a submit is done and after validation, using the GUID from the URL (as a query string for now) I use that to extend the state of the form between multiple pages so that when I save to the database I can use the GUID to link all the different tables that are affected by the multi-page form.

So an example of this is :

https://www.learnlaravel.com/applications/new/recommendations?GUID=e6376caf12

where the /recommendations is the one part of a 5 page interactive form. Each page of the form gets the GUID appended to it.

Hopefully I put it into the correct context now.

what are you trying to achieve with the GUID? If you want to maintain a state between the 5 pages of your application, you could use Session variables instead.

The GUID is used so that when each form is submitted I can use the GUID to look up the specific row in a database and update it and also all of its relationship tables.
