Hi Abbey,

they are all notices not errors. What they mean is that the variable was not set before using it the first time.

So lets say you have a php variable name $value and in the script you load the page and then somewhere in the code you have

$value = 'whatever';

you will get a notice that says value was undefined because you did not initialize it first before using it.

So to fix it, at the top of the php page you would have this..

if(!isset($value)) { $value = ''; }

this tells php that if the value is not set on page load to load it with '' (nothing)

Now this can happen with arrays and offsets as well. An offset is a part of an array.

Such as $product['price']

This happens because the developer did not set up a path for

what happens is the array is empty?

So if you look for product and the array is empty and there is no php code telling php "hey if its empty then display no records found" then you will get usually not only a notice for the array but also for the offset which would be ['price'] for example.

That is why you get those, and unless you know php you would have to have the developer fix it because they forgot to put in code to handle the case of nothing found.

Notices are not fatal errors and usually they do not effect the performance of the script unless in your case it is the offset for which sometimes its just a empty page with debug off.

Hope that makes sense.

The problem is that alot of developers (unlike me) dont take the time to initialize all their variables. All my scripts have a long list of those examples at the top of the php page. Lazy devs dont bother to do it because its not fatal and if its not fatal they dont worry about it.

However those notices will get a plugin kicked back, ross will not approve them if they have notices.

Not in the theme, there is no php in a theme.

Abbey are you sure you don't have debug and dev modes enabled at the same time?
