Woad.php

What? That doesn't make sense, it wouldn't even send it if the button wasn't pressed.

How can I be sure that when I send data with the POST method it won't be changed?

But I do I validate the forms using that code?

I have a form on my webpage. Let's say I have three fields. Username, Email, and password. For all fields I have to check if they're too short or have invalid characters. For Username I need to check if it's been taken by another user, and for email I need to check whether it's a valid email. How do I perform these checks?

OK, thanks that's better than what I was thinking of doing to check the username. But that still doesn't answer my validation issues.

I'm trying to create a members system and i'm having problems with the form validation. I want to have the validation code in a seperate file and be able to check if the username (one of the form's fields) has been taken by querying the database and comparing names. How do I do this?

I've accidentally posted. Could an admin please delete my post? Sorry.

Thanks guys for your help.

Yes, that's exactly what I wanted to do, but I couldn't figure out how to delete specific parts of the text file. Could you post the code to do all of that?

I have a shoutbox.txt that looks something similar to this: [code]<div align="left" style="font-family:Verdana, Arial, Helvetica, sans-serif; color:#FFFFFF; font-size:10px;"> <b>Anonymous</b> ? <br> <b>Anonymous</b> ? <br> <b>24.16.80.177</b> ? <br> <b>RA</b> ? <br> <b>24.16.80.177</b> ? <br> <b>asdfafdf</b> ? <br> <b>asdfafdf</b> ? <br> <b>asdf</b> ? Enterasdf Message<br> <b>Beaches</b> ? Bork bork<br> <b>Sup?</b> ? Hahaha<br> <b>Anonymous</b> ? <br>[/code] And right now I'm using this code to show whats been said: [code]<table bgcolor="#292929" border="0" align="center" cellpadding="3" cellspacing="0" width="98%"> <tr> <td valign="bottom" style="background-color: #444444; border: 1px solid #000000"><font face="Verdana, Arial, Helvetica, sans-serif" size="1"><?php include "shoutbox.txt"; ?></font></td> </tr> </table>[/code] How could I only show to people visiting the site only say the most recent 10 entries and delete the rest?

You need to search for the smile and replace it with a picture like this: [code]$message = str_replace(":)","<img src=\"/images/smile.gif\" alt=\"Smile\">",$message);[/code] it replaces any :) in the message with the smile picture, and in the last parameter you're passing in the string (in this case $message) to be searched and replaced.

Thanks

Hey guys, I just learned all of the basics about php yesterday and now I want to try creating a timer that constantly refreshes and is taken away from. For example it shows 00:00:01, which changes to 00:00:02, 00:00:03, etc. etc. but adds to the timer while the page has been created. Is that possible?
