What I want to do is eliminate the need for the viewer to type in the birth year and to have a math statement that calculates it based on the age they put in and takes into account the month and day as well to determine what year they were born, and then send that number to my database. Here is my code for my form: (I have a field in my table in my databse named birthdateyear, that I want to store the year of birth into) How do I do that?

 

<?php

session_start();

?>

<?php

//Access Tracking Snippet

//set up static variables
$page_title = "creationform.php";
$user_agent = getenv("HTTP_USER_AGENT");
$date_accessed = date("Y-m-d");

//connect to server and select database
$conn = mysql_connect("localhost", "root", "")
or die(mysql_error());
$db = mysql_select_db("smrpg", $conn) or die(mysql_error());

//create and issue query
$sql = "insert into access_tracker values
('', '$page_title', '$user_agent', '$date_accessed')";
mysql_query($sql,$conn);
?>

So, for your example, Barand, you said:

 

age = x

 

yob = currentyear - age

 

if (monthnow.daynow < mob.dob) yob--

 

So I need to name a variable and set it to the age, and then set a variable for current year - the variable age, and then I'm a little confused on the if statement. Am I right so far? Also, how would I alter the code if I have a set year I want to use? Like a year in the past? I have the form obtaining the age from the field named 'age' on the form. How would I write the variable statement to save the information to the variable from what the person types into the age field? I'm still learning how to make variables in this way.

First step is to make your month option values numeric. You can't do calculations with "September"

 

<?php
function yearOfBirth ($day, $month, $age)
{
    $yob = date('Y') - $age;
    
    if (date('md') < sprintf('%02d%02d', $month, $day)) $yob--;
    
    return $yob;
}

$year =  yearOfBirth($_POST['birthdateday'], $_POST['birthdatemonth'], $_POST['age']);

echo $year;
?>

 

echo yearOfBirth (16, 12, 62);          // 1945

echo yearOfBirth (22, 1, 59);          // 1949

This is my insert.php page:

 

<?php

session_start();

?>

<?php

//Access Tracking Snippet

//set up static variables
$page_title = "insert.php";
$user_agent = getenv("HTTP_USER_AGENT");
$date_accessed = date("Y-m-d");

//connect to server and select database
$conn = mysql_connect("localhost", "root", "")
or die(mysql_error());
$db = mysql_select_db("smrpg", $conn) or die(mysql_error());

//create and issue query
$sql = "insert into access_tracker values
('', '$page_title', '$user_agent', '$date_accessed')";
mysql_query($sql,$conn);
?>

Is there somewhere specific the code needs to be placed in order for it to work properly?

Okay, but in the function your provided, if looks like I would be referencing $age, $day, and $month, variables that I have not already set. Don't I need to set these first? In the insert.php, I just have it inserting the values from the form, but I have not set them to variables as far as I can tell. They don't have any $ in front of any of them.

The call to the function passes the POST data from the form to the function

$year =  yearOfBirth($_POST['birthdateday'], $_POST['birthdatemonth'], $_POST['age']);

 

The function's local variables ($day, $month, $age) are defined when these values are passed to them.

Is there a way to tell it to always base the calculation on the year 1992 to determine the year?

 

What exactly are you trying to do?  Maybe Barand can divine your intentions, but I can't and I suspect not many other readers would understand your last post.

I dont think you can accurately determine the birth year based on age and current year.  You don't know if they have had their birthday yet for this year.  Instead of asking their age, why not ask the birth date and get the age from that?

Because this is going to be for younger people who may not know how to accurately figure the birthyear, and I want the year based on 1992, because that is the time period this will be set in. I'm pretty sure that this calculation can be done, it's just a matter of someone helping me figure out how to write it.

If you are trying to find out how old they were in 1992, I suppose you would:

<?php
$howOldTheyWereIn1992 = $age - (date('Y') - 1992);
?>

BUT that will make them a negative age if they are younger than 16 (using 2008 for current year) since they weren't born yet.
