[[SOLVED] how to save a class file?]

But really its personal preference

[get part of string before the second upper case character]

<?PHP
$string = "JoeBloggs";
$spliter = split(",",substr(preg_replace("/([A-Z])/",',\\1',$string),1));
$forename = $spliter[0];
$surname = $spliter[1];
?>

 

This can also be used if $string = "JoeBloggsWithMoreCaps";

[[SOLVED] how to save a class file?]

Nope. Just have a file with the class in and save as PHP. Some people have file.inc.php or something so they know that file is being included somewhere.

[[SOLVED] Simple form validation]

You didn't say if you were using PHP 5 or not. But this is a PHP file email validator in it.

<?php
if(isset($_POST['submit'])) {
$to = "test@test.com";
$subject = "Contact Form";
$name_field = $_POST['name'];
$email_field = $_POST['email'];
$message = $_POST['message'];
if(!$name_field || !$email_field || !$message){
echo "You missed a field!";
	}elseif(!filter_var($email_field, FILTER_VALIDATE_EMAIL)) {
	echo "Invalid email!";
}else{
	foreach($_POST['check']  as  $value)  {
		$check_msg .= "Checked: $value\n";
	} 
	$body  =  "From: $name_field\n E-Mail: $email_field\n Message:\n $message\n $check_msg"; 
	mail($to, $subject, $body);
	echo "Thankyou for your message, you will now be returned ";
}
}else{

echo "You didn't press the submit button";

}
?>

[php dice roller]

Yeah. When they login, you would check them against a database table, then if successfull set a cookie or a session. If you need help in that area, create a new topic. 

[is it possible to check if javascript is enabled using php?]

Beacuse it is client side scripting, it isn't possible. To do it in Javascript/HTML do this.

<script type="text/javascript">

document.write('Javascript is enabled');

</script>

<noscript>Javascript is disabled</noscript>

 

 

Or you could do this:

You have like the page you want to show on a get statement and redirect the user with javascript. If the user isn't being redirected, then JS isn't enabled else if the user is Javascript is enabled for them

<script type="text/javascript">

document.location.href = "page.php?js=enabled";

</script>

[php dice roller]

<?PHP

/*

Basically have an animate image for a dice being roled or something. This is the basis of the script on what you can build on

*/

if($_POST['submit']){ //if they have pressed the submit button

$player1roll1 = rand(1,6);

$player1roll2 = rand(1,6);

 

$player2roll1 = rand(1,6);

$player2roll2 = rand(1,6);

 

$player1sum = $player1roll1 + $player1roll2;

$player2sum = $player2roll1 + $player2roll2;

 

if($player1sum > $player2sum){

echo "Player 1 won";

}elseif($player2sum > $player1sum){

echo "Player 2 won";

}else{

echo "Draw";

}

echo '<img src="'.$player1roll1.'.jpg" />'; //echo the image for roll 1 of player 1

echo '<img src="'.$player1roll2.'.jpg" />'; //echo the image for roll 2 of player 1

 

echo '<img src="'.$player2roll1.'.jpg" />'; //echo the image for roll 1 of player 2

echo '<img src="'.$player2roll2.'.jpg" />'; //echo the image for roll 2 of player 2

 

}else{

?>

<form method="post">

<input type="submit" name="submit" value="Roll dice" />

</form>

<?PHP } ?>

[[SOLVED] Random number only once]

Thanks a lot

[[SOLVED] Random number only once]

Hi,

Can someone point me in the right direction. This is what I need to do:

I need to choose 12 random numbers from 1 to 80 but they cant be the same.

If I do rand(0,80) for say 12 variables there is a chance that it could be the same as one of the others.

 

Thanks
