[Blank Page!! Arghh]

You don't even see the HTML before you start your PHP? Your doctype declaration, etc..

[Late Introduction]

I've been on this forum for more than 4 years and haven't even stumbled across this section ever.

 

Well... My name is Marcus, I'm 18 years old and live in Connecticut, USA. I enjoy doing anything a regular 18yr old enjoys doing. Partying, hanging out with friends, the norm, etc... I've been using and studying PHP/mySQL for about 5 years now. I've started off with basic HTML and CSS about 10 years ago (I know right?) Currently I'm a Junior Web Developer and Designer for a local business, that job will have to come to a rest at the end of August as I'm going off to school.

 

I've always been an honors student in school. Exceeding mostly in mathematics, mainly calculus and discrete mathematics. I will be attending the Rochester Institute of Technology starting August 31st. Majoring in Computer Science, may change to Computer Engineering though. I plan to achieve a Masters Degree in Computer Science (MS). Later in life I will return for a Doctorate in Education.

 

I'm also a YouTube Partner (share revenue with Google). I upload web development tutorials and some gadget related videos (mainly iPhone).

 

Cool.

[Confused - Need your expertise...]

What web hosting service are you using?

[How to prevent users from viewing certain pages?]

@dezkit

 

There is no need to loop through an array or a database to use a method like yours.

 

If this person is using an array they simply just need to use in_array or for a database use a more specific SELECT statement

 

$sql = "SELECT * FROM `ip_bans` WHERE `ip`='".$_SERVER['REMOTE_ADDR']."'";

[Stripslashes not working]

Is it possible there are more slashes.

 

If name is "Johnny O\\\'neal" and you use stripslashes once you will get "Johnny O\'neal"

 

If you use stripslashes twice, you will get "Johnny O'neal"

[Best Way To Set Up PHP Pages]

<?php
include "global.php"; // would be your file that includes functions, database connectivity, etc..

include "header.php"; // would be your file that is the chunk of HTML code that your page would start off with
$page = $_GET['page'];

if($page){
if(file_exists("pages/".$page.".php")){
	include "pages/".$page.".php";
}else {
	include "pages/404.php";
}
}else {
include "pages/home.php";
}

include "footer.php"; // would be your file that closes the open chunk of HTML from header.php
?>

 

Or if you don't want to use the file_exists method

 

<?php
include "global.php"; // would be your file that includes functions, database connectivity, etc..

include "header.php"; // would be your file that is the chunk of HTML code that your page would start off with
$page = $_GET['page'];
$pages = array('home','about','contact');

if($page){
if(in_array($page,$pages)){
	include "pages/".$page.".php";
}else {
	include "pages/404.php";
}
}else {
include "pages/home.php";
}

include "footer.php"; // would be your file that closes the open chunk of HTML from header.php
?>

[Help with pulling usernames from database]

$sql = "SELECT * FROM `user_signup` WHERE `username`='".mysql_real_escape_string($_POST['username'])."'";
$res = mysql_query($sql) or die(mysql_error());

if(mysql_num_rows($res) > 0){
// taken
}else {
// available
}

[MySQL UPDATE error]

That's the wrong syntax for an update query.

 

$sql = "UPDATE `table` SET `field`='".$field1."' , `field2`='".$field2."' WHERE `this`='".$that."'";

[How to disable href in certain cases?]

You should really minimize that code

 

<?php
$link = ($mp3 == "") ? $lang_t202 : '<a href="'.$mp3.'">'.$lang_t202.'</a>';

$F = "<div align='center'>
<center>
BLAH BLAH ALL YOUR OTHER HTML HERE
".$link."
REST OF YOUR HTML 
</center></div>";

?>

[Random letter based on a distribution]

Between two players you should use a database and tag on some fields like game_id,letters_remaining

 

game_id would be relevant to another table with some fields like uid1,uid2 (for users player), status (0=not started, 1=playing, 2=finished), winner (would be uid1 or uid2)

 

etc..

[not updating correctly]

You just need to set the action of the form to act with the item_id...

 

<form action="submit.php?id=<?php echo $variable_of_id_being_passed_in_previous_form; ?>">

[PHP variables in sql query?]

$sql = mysql_query("SELECT * FROM `kunder` WHERE `id`='".$row['anmoder']."'") or die(mysql_error());

[Template Page]

Facebook works off modrewrite for people who have a custom URL, or for people who don't have a custom URL they have a "profile.php?id=xxx"

 

If you wanted to have a new page "created" for each user and have it like http://site.com/USER1.php http://site.com/USER2.php you could just use modrewrite instead of actually creating the page.

[mysql_query(): supplied argument is not a valid MySQL-Link]

$id = mysql_real_escape_string($_GET['id']);

$query = "SELECT * FROM `".$tbl_name."` WHERE `site_id`='".$id."'";
$res = mysql_query($query) or die(mysql_error());

// then do your mysql_fetch_assoc, array, etc

[Why this doesnt changed!!!!]

Are you connected to a database?

 

$sql = "INSERT INTO `players` (`Skin`) VALUES('233')";
$res = mysql_query($sql) or die(mysql_error());

[Get error in mysql update line..]

<?php
$sql = "INSERT INTO `chars` (`accid`,`charname`,`sex`,`age`,`pgmg`,`dmrkt`,`history`,`carcrashrp`,`carscrach`)
	VALUES('".$_SESSION['Logged']."','".$_POST['charname']."','".$_POST['sex']."','".$_POST['age']."','".$_POST['pgmg']."','".$_POST['dmrktt']."','".$_POST['history']."','".$_POST['carcrashrp']."','".$_POST['carscrash']."')";
$res = mysql_query($sql) or die(mysql_error());
?>

[if in switch problem]

Where are you pulling the $row['Sex'] from? How are you comparing the IsValidSkin function to $row['Sex']?

 

<?php

function IsValidSkin($skinid,$sex){

$valid = array(3,4,5,6,8,17,42,50,61,65,71,74,86,92,268,119,149);
if(in_array($skinid,$valid)){
	return true;
}else {
	if($sex == 1){
		return true;
	}else {
		return false;
	}
}
}

?>

Just throw that code to the top.

[Change Tite On Submit]

Ha, my error pick up was right off the bat didn't look at the beginning of the code.

 

unset is to basically remove anything tied to the variable. For instance

unset($_SESSION['username'])

 

You want to do something like:

 

<?php
if(isset($_GET['ID'])){
echo "Tracked" . htmlentities($_GET['ID']);
}else {
echo "Title from the First page";
}
?>

[Change Tite On Submit]

<?php
if (unset($_GET['ID'])){
echo 'Title from the First page';
}
else {
if (isset($_GET['ID'])) echo 'Tracked' . $_GET['ID'];
}
?>

[function for cleaning input data.]

mysql_real_escape_string should be all you need for input, but for output you could use those.

What I interpreted
