This is a bit funky.
Maybe it's just my browser that doesn't write the end tag, or something.

Also the amount of whitespace is huge.

when making a user account system for a website

where do I start? I don't care if it's secure or not; even just having a document which says this is fine

User1:
    {
username: admin
password: AAAAAB
permissions: 777 
    }

since I didn't know how to make an actual user database that isn't a minecraft/source game server, the best I've done is this:

[URL]http://cronosdage.x10.mx/login.php[/URL]

literally combines the username and password given and adds ".htm" to the end

so user "hl3admin" pass "gaben" gives you [URL]http://cronosdage.x10.mx/hl3admingaben.htm[/URL] which is just a childish rickroll. but you can just enter anything and it will bring you to that.htm

(index won't work because my homepage is PHP)

[b]question 2[/b]

is there any way I can make a text-entry box focus on page load?

Hi, usually people use mysql for a database, and I'm guessing you don't know how to do that.

Now you can either learn mysql (it's really not that hard), or perhaps you could handle it in the php.

Seeing as how (normally) the client can't see the php code, you could just put this in the code:

if($_POST['username'] == "bananaphone" && $_POST['password'] == "hello") 
{
     // Insert code for correct users here
}
else 
{
    // yea that's no good, probably want something like:
     header("location: index.php");
}

Then again, this does not allow people to create an account and the code will get very messy if you add more than 1 person, really.

In sql, the thing you want to do is probably create a table like this (A table with a username, password, and an email):

CREATE TABLE IF NOT EXISTS `users` (
  `username` varchar(255) NOT NULL,
  `password` varchar(255) NOT NULL,
  `email` varchar(255) NOT NULL,
  PRIMARY KEY (`username`,`password`),
  UNIQUE KEY `email` (`email`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

The code would then be

// Creates a new database connection
$mysql_server = 127.0.0.1; // Database server ip address, probably not this
$database = "database_name"; // You set this when you create it
$mysql_user = "root"; // Username to get in the database
$mysql_pass = ""; // Password for the database

$identifier = new PDO('mysql:host='. $mysql_server. ';dbname='. $database, $mysql_user, $mysql_pass);

//This is the sql code needed to get a username from the database (aka it checks if the username/password combination exists in the database)
$query = "SELECT `username` FROM `users` WHERE `username`=:v1 AND `password`=:v2";
$stmt = $identifier->prepare($query);

// Safely binds the variables (to counter mysql-injection)
$stmt->bindParam(':v1', $_POST['username']);

// change the salt to something else. When inserting new users, use the same function to add the password
$stmt->bindParam(':v2', hash("aSalt123", $_POST['password'] )); 

$stmt->execute();
$query_result = $stmt->fetch();

// gets the username, if its empty, that means nothing was found.
$username = $query_result['username'];

if($username != "") 
{
     // Yay a correct user
}
else 
{
     // Darnit a wrong combination
}

I get that this is a lot though, and you'll need to set up a database (I can help you with that if you like)
After that you don't need to know sql to manually add users to the database if you wish.

Edit: Almost forgot about the textbox focusing. You could either use the "autofocus" attribute ( <input type="text" name="name" autofocus />, also super unsupported by IE 9 and lower ), or you could use javascript, as shown [URL="http://stackoverflow.com/questions/3383429/setting-focus-on-an-html-input-box-on-page-load"]here[/URL].

thanks a lot; I haven't used mysql in years

[QUOTE=mdeceiver79;42945710]Multisite real time reporting for epos, for now will just be sales with some forms for cash declarations. Once released more modules will be added for loyalty, stocks etc.

The users will have an overview of events that day then be able to quickly filter and drill down on events and transactions for full details.

edit: also an alert feed flagging suspect events, similar to facebook notifications.[/QUOTE]

minimizing all the js as it goes out would make it significantly more difficult for somebody to steal it and reuse it.

also doing lots of things with no comments and having unhelpful or misleading function names.

Waterfox.
When I press Suitable for/change the price range, nothing really happens. And I have to press load more to see it.
And maybe it would be a good idea to instead of having each shuffle in the shuffle viewer, have x of y shuffle there.

What would be the easiest way to delete elements from a list using a link on the page? This is for an assignment so i think i have to use a link... I can't use jQuery either. Is there some easy ajax trick?

Ok so i have to use a GET request on a local separate php script then somehow retrieve the results as formatted XML.

$opts = array('http'=>array('method'=>"GET",'header'=>"Accept-language: en\r\n"));
$context = stream_context_create($opts);
$result = file_get_contents("http://localhost/1/search.php?item=" . $_POST["item"], false, $context);

However, $result is an empty string...

Here is search.php

<?php
		
	function searchForAllInstances()
	{
		$item = $_GET["item"];
		$xml = new DOMDocument;
		$xml->load('db.xml');
		$matches = getMatches($xml, $item);
		
		$xsl = new DOMDocument;
		$xsl->load('db.xsl');

		$proc = new XSLTProcessor;
		$proc->importStyleSheet($xsl); 
		return $proc->transformToXML($xml);
	}
			
	function getMatches($doc, $item)
	{
	    $xpath = new DOMXPath($doc);
		$highest = '';
		$result = $xpath->evaluate('//order/item');
		$array = array();

		foreach ($result as $node)
		{
			if ($node->textContent == $item)
			{
				array_push($array, $item);
			}
		}
		return $array;
	}
			
	searchForAllInstances();

If you can edit the other PHP file then just use JSON instead.

json_encode($data);
json_decode(file_get_contents($url), true);

[twoski]

I don't think we're allowed to use json. Part of the assignment is that we have to use a GET request and search.php has to be a separate file.

[CBastard]

[QUOTE=twoski;42978429]I don't think we're allowed to use json. Part of the assignment is that we have to use a GET request and search.php has to be a separate file.[/QUOTE]

XML and JSON are just data formats. The reasons you've given don't rule out JSON.

[url]http://localhost/1/search.php?item=15[/url] could output either JSON or XML for item 15.

If your teacher has had you learn to use XML then use XML for this, but you really should know that there is a better way to do it.

[Maqtiah]

So after some serious time of configuring SFTP and arguing with LithiumHosting I finally got it working, they were saying I shouldn't use SSH, and one said I should. How weird, so I told them which one of them was speaking the truth and suddenly they realize they've put wrong information in their knowledge database.

Such a fail, but it works so yay me!

I'm doing an assignment for school but I have no idea on how to solve this, basically we got this table as shown below:

[IMG]http://i40.tinypic.com/nb43mb.png[/IMG]

The form at the top should figure out between the two categories what the customer needs in the table.

Now logically I would say i should set a variable for each choice(?) - And then say if this plus this link to this. Or is that wrong, have no idea how to tackle it really. :suicide:

If you need to process the selection server-side I would do something like that.

<form name="weirdForm" action="someEndpoint" method="POST">
	<label>Hvilken something Moofy</label><br/>
	<input type="radio" name="selection1" value="option1" checked/>Mit har er turist<br/>
	<input type="radio" name="selection1" value="option2"/>What language is this?<br/>
	<input type="radio" name="selection1" value="option3"/>Danish?<br/>
	<hr>
	<label>Er dit blah bananas</label><br/>
	<input type="radio" name="selection2" value="option1" checked/>Ja<br/>
	<input type="radio" name="selection2" value="option2"/>Neg<br/>
    <hr/>
    <input type="submit" name="submit"/>
</form>

And then check the contents of the selection1/2 POST variables to determine what to output.

In PHP for instance:

$_POST['selection1']; // Will be either option1, option2 or option3
$_POST['selection2']; // Will be either option1 or option2

If you want to do it client-side, you can use the same code without the submit button, and then listen for the "change" event using JavaScript.
