Stuck on Idea Silver badge Maker Activation

initiate();
function lifeSupportCheck () {
//
}

Do you know the answer to the one which says:Call the function you just wrote, in the same way you called initiate,then press ‘run code’

Do you know the answer too this one :

Firstly, a function in programming is basically a named block of instructions - the task gives you one of those called lifeSupportCheck.

The block of instructions is everything in-between those { curly } brackets, although of course the { and } in your lifeSupportCheck is basically empty aside from the // comment. Therefore it's a function which actually wouldn't do anything if it were used, but that doesn't matter. The function can still exist and do-nothing when the program actually uses it

However, the code in your task only creates ('defines') the function (that's what the curly brackets are doing - i.e. linking the block of instructions with the name) - the code doesn't actually use that function. So even if it did contain any instructions, the program would never run those. The phrase 'call the function'. is just a programmer's way of saying "use this function as if it were a single instruction in your program to run it".

'calling' a function is a matter of using its name and the (rounded brackets), and ending with a semicolon. Your task mentions "the same way you called initiate" as a clue that you already have an example line in your program which calls the initiate function by doing this:

initiate();


One last point on where to put the line - Programming languages' instructions flow downwards in-sequence, just like Written English, so the position in your program where you call the function is important. It needs to happen after the closing-curly-bracket } because the code needs to have finished the sequence of actually creating/defining the whole function before it's possible to actually call it

(Just remember the order that you do things matters, like when making a cup of tea, you can't pour hot water before the kettle has finished boiling)

Not trying to be rude, but could you shorten that ?

Sorry for the long answer! It's useful to know what the code means anyway


And an example of calling a function which is this (including the name, brackets and semicolon at the end) :

initiate();

so it's just asking you to 'call' your function, which is lifeSupportCheck();

does anyone know the answer for

$review = $_POST['review'];

insertIntoDatabase($review);

i was stuck on this forever. in your notepad theres a code with escape tags. you just gotta follow that. can't remember exactly but i think the answer is something like

$review = escape_tags($review);
and just put that in the blank line between the two you already have.
its not much but play around with it and you'll get it

I'm stuck on the Idea Silver badge on the first functions. This is what I typed down:
initiate();
function lifeSupportCheck() {
initiate();
}

Where have I gone wrong?

$myFormData = $_POST['comments'];

insertIntoDatabase($myFormData);


Does anyone know how to sanitise

Nevermind, I completed it, i don't need help with it ;-;
