Any solution will rely heavily on RewriteCond. You check %{HTTP_HOST} for a leading "www.", and you can use the "-d" and "-f" to test for directories and files, respectively. Try this: RewriteEngine on # external redirect; we want the visitor to see that "www." is removed RewriteCond...

Here's a basic example. I'll set up a live test page and post a link later. <div> <div id="content">...</div> <div id="loading"><div class="vcenter"><img src="/images/loading" alt="loading..."/></div></div> </div> <script type="text/javascript"> $('#loading')[0].fadeSpeed=500; function...

To get #panel to contain floats, use #panel { overflow: auto; }. Explicitly altering the height is brittle and will break if the font size changes or if the text ever takes up more than one line. To get more prompt help, include a link to a live version of your minimal test case.

When asking about code, be explicit about the behavior you expect and the behavior you get. "It doesn't work" tells us nothing. If you can, use something like Fileinfo to identify file type. An associative array is more efficient and (IMO) easier to read than a series of string...

file() doesn't have problems with newlines. It doesn't read any content, it only opens the connection.

The JS solution you posted has 3 disadvantages: higher network utilization, requires the browser to support JS and requires editing the source to add or change quotes. You could pick the quote server side. Advantages: works if JS is disabled or not supported by the browser and uses less...

Single quotes delineate string literals, so this query is comparing the string 'thread' to (e.g.) 'test', which will always fail and thus return no rows. The only time it would succeed is if $thread == 'thread', in which case every row from `comments` would be returned. Use either back quotes...

When posting code, use the [code], [html] or [php] tags as appropriate. If you're generating an SQL query that isn't working, check the generated statement. If you don't have a PHP debugger (e.g. Eclipse+PDT+XDebug), add some scaffolding to the script to print the statement . You'll see...

Make sure you include a "RewriteEngine on" directive in your .htaccess file before any other mod_rewrite directives.

There is no ":current" pseudo-class in CSS1, 2.1 or 3. Are you using jQuery?

It's still unclear exactly what you need. Do you want to know how to handle login? How to store user data? How to ensure only a user (or admin) can view the user's data (i.e. authorization)? Something else? If you don't know what help you need, no one else can tell you.

There are some issues with cookies: they're blocked or disabled on some browsers, they shouldn't store sensitive information and they can be set client side, so they can't be trusted. Better use sessions (assuming you're using PHP; you should always state the software environment). Note that...

Take a look at my take (and the style that achieves the effect). It works for IE >= 7, but not IE6. It relies rather more on absolute positioning than I usually like, but it's fairly clean.

Browser detection and serving different content for different browsers is a bad route. If you can't get the same CSS to work on IE, the least evil route is to use conditional comments in the web page to give IE a different style sheet. At least that way, the content is (essentially) the same...

It's amazing how many bugs are caused by typos. Even with modern IDEs' code colorers, auto-indentation, auto-completion and name checkers, they still happen. For instance, no IDE I know of could have caught your typo. Firebug is frickin' awesome.

Use Firebug (2) with Firefox, Safari 4's built-in debugger or Visual Web Developer Express with IE (Opera's dragonfly is still in development) to debug JS. After viewing and clicking the links, the test page will log two errors in the browser's error console. For Safari: ReferenceError: Can't...

I tried my cron test script, but it didn't appear to run. The job was scheduled in crontab.

What version(s) of IE? Always describe the software environment. Also, always explicitly describe what you want and what you get so we don't have to intuit what's "proper". The fragmentary conditional comment: [if IE 6]> <style type="text/css"> html { overflow-y: hidden; } body {...

From the form source, the message should be stored in "notebody", not "body". As for the other fields, they might be dynamically generated when the page is, in which case the above probably won't work. What your applet would need to do is request the page, parse it and extract the field names...
