nginx + [url=http://code.macournoyer.com/thin/]Thin[/url] if you have a server with 128 MB RAM like I do :v:

You do realise you can test locally, in case that's what you mean, right? "rails s"

just a quick question, can anyone help me with this snippet of code, it keeps giving me the error...

[/QUOTE]You know you can stick variables directly into double quoted strings, right? No need to use the concatenation operator.

Also use PDO

[Dragory]

You have an additional ' at the end of $date, thus making it '25/08/11''.

Ok so basically all I want to do is if a session is running/active I want to hide one div tag and show another. How can I do this?

[url]http://jamglobe.net/[/url]

Just wanna hide that top bit with the please register / login boxes and display "Welcome, username"

Here's the code for the top bit, it's probably a mess and a bad way of doing it but I'm fairly new to it all.

<div class="register">Welcome, user. Please sign up... <img src="icons/user_go.png" width="16" height="16" border="0" usemap="#Map" />
  <map name="Map" id="Map">
    <area shape="rect" coords="-1,1,20,20" href="register.php" />
  </map>
</div>
<div class="login">
  <form method="post" action="checklogin.php" style="width:530px;height:22px;float:right;" name="loginform" id="loginform">
  <input type="text" name="username" value="Username" id="username" />
  <input type="password" name="password" value="password" id="password" />
  <input name="image" type="image" value="submit" src="icons/accept.png" style="margin-top:2px;" alt="SUBMIT" align="right"  width="16" height="16" border="0" />
  </form>
  </div>

Use php to include a file with everything you want to be shown when the user is logged in and include another file if they aren't. And don't use image maps. Use <a></a> tags instead.

Alright I'll give it a go, and thanks for the advice I'll bear that in mind.

In [url=http://pusher.com/]this site[/url], the container holding the gallery thingy at the top is called the "masthead", and each of the page things are marked as "hero" - what does the "hero" mean?

It's ridiculous how hard it is for me to try and say this plainly (or even just paraphrase the following article), but it's generally just a term used for a large promotional image. Apple makes heavy usage of Hero images and to great effect.

This article explains it better than I ever could:

Is there a way to copy one blog content to another in real time?

I thought RSS feeder would be sufficient enough, but I realized that RSS copies only the title and first few lines of the blog post.

Depends on what blog platform you're using. Some support JSON, so you can probably use that.

Could anyone tell my why this doesn't center the inputs?

CSS:

div.field {
	margin: 0 auto 5px;
}

HTML:

<form>
	<div class="field">
		<input type="text" name="username" /> 
	</div>
	<div class="field">
		<input type="password" name="password" />
	</div>
</form>

Go easy on me i just started learning today :P

Try margin: 0 auto; or you could just text-align: center; the form.

[MayorBee]

margin: 0 auto; didn't change anything but text-align fixed it, thanks. Still somewhat puzzled as to why margin didn't work though.

div.field needs a width.

[QUOTE=R1Z3;31968102]div.field needs a width.[/QUOTE]

width: auto; should do.

I just started coding JQuery and I have ran into a but of a wall. I am trying to make it so when I click on a div class (button#), it will open up a page (text#), by sliding the div that is open up. Then the other div would open after a delay of 0.2 seconds.

$(function(){
		
	$(function(){
		$('.text1').hide();
		$('.text2').hide();
		$('.text3').hide();
	});
	
	$('.button1').click(function(){
		$('.text2').slideUp(600);
		$('.text3').slideUp(600);
		$('.text1').slideDown(600);
	});
	
	$('.button2').click(function(){
		$('.text1').slideUp(600);
		$('.text3').slideUp(600);
		$('.text2').slideDown(600);
	});
	
	$('.button3').click(function(){
		$('.text1').slideUp(600);
		$('.text2').slideUp(600);
		$('.text3').slideDown(600);
	});
	
})

This is what I have so far, as you can tell it only closes the divs that are possibly open and opens the selected div with out a delay. I have tried queues and delays but I failed, please help.

I just figured out how to do it i feel dumb. D=

$(function(){
		
	$(function(){
		$('.text1').hide();
		$('.text2').hide();
		$('.text3').hide();
	});
	
	$('.button1').click(function(){
		$('.text2').slideUp(600);
		$('.text3').slideUp(600);
		$('.text1').delay(800).slideDown(600);
	});
	
	$('.button2').click(function(){
		$('.text1').slideUp(600);
		$('.text3').slideUp(600);
		$('.text2').delay(800).slideDown(600);
	});
	
	$('.button3').click(function(){
		$('.text1').slideUp(600);
		$('.text2').slideUp(600);
		$('.text3').delay(800).slideDown(600);
	});
	
})

Would someone mind posting some book recommendations for CSS, HTML, PHP, and whatever else.

Thanks.

You have a $(function() {}) within a $(function() {}). I don't think there is exactly anything wrong with it, but it is redundant.

That is so I can reference the code at the top of my html and have the js still run.

I could make it this but the way I have it is shorter.

$(document).ready(function(){

bla bla bla

})

@Gaza Pen Pal

I don't know about books but if you are just starting to code than Think Vitamin is a good source. Think Vitamin has a lot of great videos on html-html5 css-css3 jquery java ruby and other stuff. It costs money to watch all the videos, but they have over 400 of them.

[TheDecryptor]

You can leave the first $(function()) call, but the second one is redundant.

Edit: This

$(function(){
		
	$('.text1').hide();
	$('.text2').hide();
	$('.text3').hide();
	
	...
	
})

Is equivalent to this

$(function(){
		
	$(function(){
		$('.text1').hide();
		$('.text2').hide();
		$('.text3').hide();
	});
	
	...
	
})

[Dark7533]

Oh he was talking about there, I fixed it, thanks.

Is there any way to shorten the code so I don't have to use the slideUp function twice or is there a way to find what one is down then make it slide up?

For your case, I would recommend doing a few things in your HTML structure.

[html]
<nav>
<ol>
<li id="button1">Show Text 1</li>
<li id="button2">Show Text 2</li>
<li id="button3">Show Text 3</li>
</ol>
</nav>
<div id="container">
<div id="text1" class="text">Stuff</div>
<div id="text2" class="text">Stuff</div>
<div id="text3" class="text">Stuff</div>
</div>
[/html]

Javascript:

$(function() {
    $('.text').hide();
    
    $('#button1').click(function() {
        $('.text').slideUp(600);
        $('#text1').delay(800).slideDown(600);
    })
    
    // ...
});

This should make things easier to maintain.
