Handle This Error

Copy linkTweet thisAlerts:
Nov 29.2021

I’m posting this from my phone. So I’ll explain this without too much code if I can.

I have an object, let’s call it a car class. I’m creating this on my public index page like this..

[code]
$car = new car;
$car->getID($_GET[‘Id’]);
[/code]

Later on in my code I’m using other methods like

[code]
echo $car->getColor();
[/code]

it all works nicety until I have an Id of something that doesn’t exist.

how should I manage this?

@ginerjmNov 29.2021 — If you are not validating the input before calling this method then you have to modify the method to handle it. Obviously.

Obviously.

the first question is how? Or what way is best because…

second secondly simply echo'ing out nothing delivery’s bad page.

is there another way to do something here?

I’m tempted to do a conditional query at the very top and redirect using headers if my get element is not an integer or not existent.

but that doesn’t cater for the scenario where the database doesn’t find a record.

@NogDogNov 29.2021 — getID() should return something (true/false?) so that you can test the result when you call it, and proceed accordingly or output an error (or whatever makes sense).

it returns an object if it finds a result and builds it.

When I do my getById code, can I do a conditional statement around that?

then all over mt page I have properties being retrieved and printed, so I need to wrap all of these in a conditional statement if set then else etc?

One of the functions is getting a JSON file and loading it into a JS file so is messy

Just an idea. Not that smart, but might give some other ideas :-)
