[Help with arrays and for loops, any help would be great!]

We have too little information to help you out it's like asking to chop a tree without having a tree. We need to see some code.

[Help with arrays and for loops, any help would be great!]

You don't need to do that if your array is setup correctly with each product having its' own unique key. May I see your array? Grouping by description is not recommended I would recommend to group by id.

 

Off-topic:

 

I think you should take a look at SQL it could make things a lot easier for you.

[Help with arrays and for loops, any help would be great!]

Could you tell what exactly you are trying to do? What's your goal? Because what you are asking is very unusual since you can't stop a loop from "restarting". You can select keys individually however. Like so:

$product_description = $products[0]['product_description'];

But I don't know how your array looks like and I am not clear on what you are trying to do.

[[PHP] How to block user after 3 fail of submiting wrong information]

Why would you use sessions for this? If I were to do this I would just delete my sessions and retry.

 

I found this on google which might be helpful.

 

Good luck!

[Sessions are saving but not working]

array(0) { }

 

Thats what it returns

I am almost sure it must be in the PHP settings but I dont know what exactly it is.

It works on my laptop where I have set up my own webserver. But on the VPS (where the problem happens) I use appserv. And I used to have it earlier with appserv and he changed it either in the apache or php settings

[Sessions are saving but not working]

<?php
$login = file_get_contents("tpl/contents/login.html");

if(isset($submitlogin)){
//Query setup
$loginquery = "SELECT 
				UserID, 
				Password 
			FROM 
				Login 
			WHERE 
				UserID='".mssql_real_escape_string($username)."' AND 
				Password='".$password."'";
$loginresult = mssql_query($loginquery);
$countrows = mssql_num_rows($loginresult);

if($countrows == 1){
	$_SESSION['username'] = $username;
	$_SESSION['password'] = $password;

}
if($countrows != 1){
	$login .= "<span style='color:red'>Login Failed</span>";
}
}
echo $_SESSION['username'];
//Get template
$template = str_replace("%ucp%", $login, $template);
?>

 

Its included in a file where session_start(); has been used and I tested it with other ways too like

 

<?php
$_SESSION['username'] = "test";
echo $_SESSION['username'];
?>

When I remove $_SESSION['username'] = "test";

It doesnt echo it anymore

[Sessions are saving but not working]

The sessions do save I have checked the directory, but somehow it doesnt work at all. I cannot call the session after going to another page. I am sure the code is correct I have tested it on many ways. It must be my PHP or apache settings but I have no idea what and where it is.
