PHP pre-defined error displaying

[Dormilich]

none, 1 yr extension, 2 yr extension

now we have the meaning (intention) of the choosable options, but what are the values sent to the server script?

[Matt Morgan]

Not really sure, assuming a number(s)?

[Dormilich]

and how would you check if something is a number?


edit: hey, this is my 6,000th post!

[Matt Morgan]

Another guess = $number?

[Dormilich]

? ? ?

[Matt Morgan]

I'm not really sure. Error messages shouldn't have '$strlen' is about as far as I'm following, although it's sending numbers, but it shouldn't.

Hey Dormilich congratulations on your 6000

[Dormilich]

why shouldn’t it send numbers?

[Matt Morgan]

so it's sending numbers as representations of:
none, 1 yr extension, 2 yr extension?

[Dormilich]

you wrote the HTML, didn’t you?

[Matt Morgan]

Yes,I know how to write it, just don't understand how it then relates to the functions in PHP.

[Dormilich]

your input does not relate to PHP functions (unless I misinterpret the term "relate"). what you have is input (either from $_GET or $_POST […]) and you need to validate these strings by means of PHP function. which function(s) to choose for that purpose depends on what the input is supposed to be. e.g. strlen() gives you the length of the string, if that is a statement you can work with depends on your validation strategy.

[Matt Morgan]

so you're suggesting not having POST and having GET instead?

[Dormilich]

it doesn’t matter whether it is $_POST or $_GET, the validation required is the same.

[Matt Morgan]

So if that is all fine, then it is purely the second half of the error messages causing the problems, but I don't know/ understand what to change these to.
