and another function I was working on is a date of birth selection option, since my supervisor suggested that I include it in my page to filter out users who are below 15 years old.
Code
<html xmlns="http://www.w3.org/1999/xhtml">
<form method="post" action="<?php echo htmlspecialchars($_SERVER['PHP_SELF']); ?> ">
<select name="day"><?php
for ($i = 1; $i <= 31; i++) {
echo "<option value=\"$i\">$i</option>\n";
}
?></select>
<select name="month"><?php
for ($i = 1; $i <= 12; i++) {
$monthname = date('F', mktime(12, 0, 0, $i, 1, 1930));
echo "<option value=\"$i\">$monthname</option";
}
?></select>
<select name="year"><?php
for ($i = 1930; $i = 2010; i++) {
echo "<option value=\"$i\">$i</option>";
}
?></select>
</form>
</html>
the message I got for this one is:
Parse error: parse error, expecting `')'' in C:\wamp\www\dateselection.php on line 4
and another thing, does anyone know how I can implement the date selection code into the registration form?

Rank: Guest | | I'm not sure if you're trying to do something odd here, but might you want to replace $text with $username and whatnot to actually test them? Looks like you might've copied template code and forgotten to replace the vars
Code
$username = htmlspecialchars($_POST['username']);
if (preg_match("/\s/",$text))
{
die("do not use spaces, tabs or newlines in your username");
}

Rank: Mad User | | ok, I've fixed the errors in both code, while the first one kind-of works, (I still haven't made the databases yet), it seems fine.
I still have a problem on the birth selection code, though. It runs without any errors, the drop-down boxes doesn't even show any numbers (day, month, year) for me to choose from. any idea why this happens?
the amended code is:
Code <html xmlns="http://www.w3.org/1999/xhtml">
<form method="post" action="<?php echo htmlspecialchars($_SERVER['PHP_SELF']); ?> ">
<select name="day"><?php
for ($i = 1; $i <= 31; $i++) {
echo "<option value=\"$i\">$i</option>\n";
}
?></select>
<select name="month"><?php
for ($i = 1; $i <= 12; $i++) {
$monthname = date('F', mktime(12, 0, 0, $i, 1, 1971));
echo "<option value=\"$i\">$monthname</option>";
}
?></select>
<select name="year"><?php
for ($i = 1971; $i <= 2010; $i++) {
echo "<option value=\"$i\">$i</option>";
}
?></select>
</form>

Rank: Hacker Level 1 | | Another thing you may want to look at is the number of days in the month. You have it loop through and set the days to 31. I want to be born on February 31st!
You may want to have the month and year selection first. this will then reflect the day loop. just remember the months that have 30 days, the ones that have 31 days, and the one that has 28 or 29...This will help you make this form a lot better.

also, I'm still stuck trying to figure out how to subtract from the selected date and the date the user signed up, and then figure out if the user it at least is 15 years old (a restriction placed by my project supervisor), and this also results in me hitting a wall most of the time.

Here's one way you can go about doing it:
http://www.daniwe. . .4794.html#
Found by googling "age verification script".
And here's the method I mentioned to you in IM last night:

Found by googling "php date difference".

I know I'm doing it wrong, I know the concept, but I'm still stuck trying to implement it into code.
I''ve been at it all morning, now I'm beat. Maybe I'll have better luck tomorrow.

This should work:
Code $date = mktime(0,0,0,$_POST['month'],$_POST['day'],$_POST['year']);
Just have your code check to see that the post variables are set (meaning that the user clicked submit), and then make the date object.

Code
if( $month == 6 || $month == 8 || $month == 9 || $month == 11 )
{
$maxday = 30;
}
elseif( $month == 2 )
{
if( $year % 4 )
{
$maxday = 28;
}
else
}
$maxday = 29;
}
}
else
{
$maxday = 31;
}
Please do not mind the crap code, but you get the gist.

Please do not mind the crap code, but you get the gist. Might go wrong in February 2100 though, as that's not a leap year. Y2.1K Bug? 
(Yes you did say the code was crappy, but that doesn't have to mean it's also incorrect.  )

Rank: Newbie | | Here is some pseudocode from wikipedia on the subject of leap years that could easily be included in your code.
Code
if year modulo 400 is 0
then is_leap_year
else if year modulo 100 is 0
then not_leap_year
else if year modulo 4 is 0
then is_leap_year
else
not_leap_year
Also, the reason nothing major happened with y2k is that many programmers were hired specifically to make sure that their companies applications were y2k compliant and would not malfunction. Years of work went into making sure that nothing happened.

here's the code:
Code <?php

elseif ($i == date('j'))
{

$sel = ' selected';

$sel = '';
}
$monthname = date('F', mktime(12, 0, 0, $i, 1, 2005));
echo "<option value=\"$i\"$sel>$monthname</option>\n";

$sel = ' selected';
} else {
$sel = '';
}
echo "<option value=\"$i\"$sel>$i</option>\n";

now can anyone figure out what's wrong, or does this happen only to me?

Rank: God | | The final for loop you have is:
for ($i = 1971; i <= 2010; $i++)
Missing "$". Should be:
for ($i = 1971; $i <= 2010; $i++)
Runs perfectly fine for me now.

Rank: Mad User | | yeah, after I posted it, only then did I check the script again only did I noticed what I did wrong, and it worked fine. should've checked first before posting it at the forums.
I have several questions. Firstly, I'm still stuck with the age limit restriction, and I've already figured out how to make one, except that I have to store the birthday in the array, and that I can't make it include leap years.
my plan is to make the date selected by the user being stored into an array, and from there subtract it with the date of registration, and that he has to be at least 13.
here's the code I found from PHP Builder:
Code
<?php
function validateUserAge($bday, $min = 13)
{
list($day, $month, $year) = explode('-', $bday);
$minYear = date('Y') - $min;
if ($year >= $minYear)
{
$age = calculateAge($bday);
if ($age < $min)
return false;
}
return true;
}
?>
<?php
function calculateAge($bday)
{
$birth = strtotime($bday);
$ageStamp = time() - $birth;
$year = 60 * 60 * 24 * 365; // not accounting leap years
return floor($ageStamp / $year);
}
?>
<?php
$minAge = 13;
$bdays = array("10-09-1990");
foreach ($bdays as $bday)
{
if(validateUserAge($bday, $minAge))
echo "user is old enough to enter<br />\n";
else
echo "you have to be at least 13 to enter";
}
?>
[addedon]February 2, 2010, 1:43 pm[/addedon]the second problem is that I've also made another PHP file that basically adds data into the database I've created, but it seems I've also hit a wall with this one.
Code
<?php
$connect = mysql_connect("localhost", "fuser", "projectpass") or die ("connection could not be established.");
mysql_select_db("mp3site");
//insert data into musician table
$insert = "INSERT INTO musician(musician_id, musician_type, musician_name, musician_genre)" .
"VALUES (1, 1, 'Carburetor Dung', 1), " .
"(2, 1, 'Instake', 2), " .
"(3, 1, 'Second Combat', 3), " .
"(4, 2, 'T.I.M.', 1), " .
"(5, 1, 'Sarjan Hassan', 4), " .
"(6, 1, 'LAW', 5), ";
$results = mysql_query($insert) or die (mysql_error());
//insert data into musician type table
$type = "INSERT INTO musiciantype(musiciantype_id, musiciantype_type) " .
" VALUES (1, 'Band'), " .
" (2, 'Solo artist') " .
$results = mysql_query($type) or die (mysql_error());
//insert data into genre table
$type = "INSERT INTO genre (genre_id, genre_type) " .
" VALUES (1, 'Punk Rock'), " .
" (2, 'Rock'), " .
" (3, 'Hardcore') " .
" (4, 'Metal') " .
" (5, 'Indie') " .
$results = mysql_query($type) or die (mysql_error());
echo "Data inserted ";
?>
the error I got was:
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1
but what was there in line 1? This problem happens on both WAMP and XAMPP, so do I have to add the data into the site through PHPMyAdmin?

$connection = mysql_connect( $host,$user,$password ) or die( "Cannot connect to DB: ".mysql_error() );
$data = mysql_select_db( $dbname, $connection );
you forgot to tell SQL that you NEED the database connection.
Try that and let me know.

... He wouldn't be getting a SQL error if the connection wasn't open. The second argument to select_db (the connection reference) is optional. He got an "error in his SQL statement" because he has an error in his SQL statement:

You're missing a space between ) and VALUES, and you have some sort of lingering comma at the end of the SQL statement.
I know this is hard to believe, but a web server will often tell you what's wrong if:
1. You allow it to by showing errors.
2. You pay attention to the error messages it shows you.
