[SOLVED] Beginner Project, small problem holding me up

Stagnate · September 19, 2008

Hey guys,

My project is a small one to get started with PHP, I hope to build this up from a simple framework that I am currently working on.

Im trying to make a site my myself and friends to add events to such as parties/dinners etc. Anyone can add to the site without a username and password but an activater is sent to the persons email so it can be added or monitored. I give each entry a random value to make them unique... This is where my problem is at.

The problem I am having is that I cant get the $eventid to post through to connect.php.

I must stress that I am a beginner so my code is probably horrible Any tips are greatly appreciated

You don't seem to be placing this event id inside any form component? And I looked at connect.php, and it doesn't seem to be trying to get an event id variable?

Stagnate · September 20, 2008

ah, so i want a hidden input?

like : <input name="$eventid" type="hidden" value="$value" />

or something like this?

waynew · September 20, 2008

Why don't you just do this?

$name = $_POST['name'];
$day = $_POST['day'];
$month = $_POST['month'];
$year = $_POST['year'];
$description = $_POST['description'];
$address = $_POST['address'];
$email = $_POST['email'];
$eventid = rand(1,90000);

Also, what is the event id for?

Stagnate · September 20, 2008

I wanted to have an event ID for each event for the activation, so when the email gets sent to the person how uploads it so that the event can be activated :S. Initially each event as it gets uploaded is set to Active=0, the link that is generated by the eventid sets the active to 1 and it can be seen.

I dnt want to use just the Auto-incremented because someone could just go through and activate 1,2,3,4....

waynew · September 20, 2008

Why not just encrypt each of those 1,2,3,4's?

$event_id = md5("randomsalt".$primary_key_of_table);

Ok I got it Thanks man, I didnt realise that variables must be put into components . Still got lots to learn it would seem.

You do know that somebody with Opera or the patience to save your webpage and edit the HTML will be able to create their own event id don't you?

Yeh should be all good for now, ill look at a bit of security in the future.
