I have another doubt..Email ID:</b><input type="text" name="email" size="20" />this will give output with a box for email id to be entered..how to make it show without a box?

thanks alot justsomeguy .. you are always informative..it worked fine when I set 777 permissions to "images" folder but I know it is not safe!I will try your codings and let you knowThis is the error message:It can't create the image file to write to. Either it would not have permission to do this or the path is incorrect, if permissions were the problem I think it would specify that. I suspect the path because it might be trying to open a file in a folder called images inside the include folder, and I'm thinking the images and include folders are parallel, not nested. There is a function in the captcha class called get_filename that looks like this:function get_filename($public="") { if ($public=="") $public=$this->public_key; return "images/".$public.".".$this->imagetype; }Change this function to return the absolute path instead of a relative path. That would make it like this:
function get_filename($public="") { if ($public=="") $public=$this->public_key; return "/home/megax/public_html/images/".$public.".".$this->imagetype; }Reply back if that works.

I hope I would get a good reply from someone who really knows what the issue isYou expect us to count till 114? Is there something very obvious that I am missing here?

I have a php verification / landing verification / image verification page. It worked fine before,Now i get this error after uploading and I dont see the image.Warning: imagepng() [function.imagepng]: Unable to open 'images/b804e0.png' for writing in /home/megax/public_html/include/functions.php on line 114What would be wrong?

thanks alot.. i will try this

Since I am a newbie, I dont understand thisHere's an good example for starter: http://www.weberdev.com/get_example-3913.html(Just google on "php image code generate" or "php image validation generate" or something like that)And instead of just rand(0,9) for just numbers, in the example, you can use chr():...// Get one random number$rand = rand( 54, 116 );// If it's less than 65 it's an number (0-9)if ($rand < 65) // Get the right ASCII $rand = 48 + ($rand - 54);// If it's more than 90 (uppercase: A-Z)else if ($rand > 90) // Get the right ASCII $rand = $rand + 6;$str .= chr( $rand ). " ";...
Isn't the best or most clear code perhaps, but it should generate a random character (0-9, a-z or A-Z).

How to add visual confirmation page? Something like, when someone goes to www.example.com, they will see any random numbers like turing numbers to enter to index page.Yu could passwordprotect all pages ore add a visual confirmation function, however I doubt this will do anything against a DDOS sinds it will still connect to your server and eat your badwith the only affect possibly is that they can't go for your biggest file instantly.Ruud Hermans -
Hello everyone, Hope you all fine here. I am in need of a help. Anyone know how to add a DDOS protection first page for a website?

It works just fine..Thank yallOkay. You would have the form send data to redirect.php and method would be GET. you also need to have the input box named "username".Its quite simple. Redirect.php gets the data from the form and takes the user to [username input].php using the header() function. -
This aint work. I would like to get some more explanation. Pleaseyou could have a page called redirect.php, which you send the info from the form to in GET, which then redirects to [input_username].phpredirect.php would look something like this:<?php$username = $_GET['username'];header( "Location:$username.php" );?>I think. im also in a bit of a hurry, so that might not work -

Hi,Thanks alot for your help! It should go to the inputted username (inputted username.php)uhm.. the form isnt that hard to do:<form method="post" action="username.php"><input type="text" name="username"/><br/><input type="submit" name="submit" value="GO!"/></form>
But what i dont get is if you want it to go to the page of the inputted username, or if you just want it to go to username.php...More explaining please.

Thanks much for your reply. I bought this flash template Readymade. They gave me the .fla file too though.I dunno much about flash. Since it is a readymade template, I can edit the content of the flash template. I didnt know I have to edit flash source file to get this action to be done.
The output is a single flash page (index.html or php) and I have added a link in that flash page that goes to signup.php (which is not a flash page and it is a different HTML page, no relation between index flash page and signup form page)So, no other way I can add a ref like I said before other than this?
I dont know this. I would be very happy if you give me more details. Where and how to add this code?CODEif(isset($_GET['ref'])){//do whatever to add the referal to registering} -
I am very glad to be a member in this forum. I hope I would find a solution for my need here :)I know nothing about flash, so please dont mistake me if this is a dumb question :)Well I have a flash template. I use a link there for signup (signup.php)It opens to a new page - http://sitename.com/signup.php.Signup form contains details like -username :state:country: ....these details are sent to my mail when someone signup. What I need is.. I wish to add a referral system. Something like http://sitename.com/?ref=*somenumbers*So when someone uses this referral URL and click the signup link, I need this option in signup form Referrerd by *123* and this referral detail asusual sent to my email when someone signup along with the signup form details (name, state, country ... and Referred by *123*)I dont want to use database here because I am not sure how to handle databases. The index flash page I will use is index.phpI would be reallllllllll flad if someone help me with this with a detailed code.Advance thanks...Janice
stats
in PHP
Posted
i have created a page like this.. i dont use any database for this..actually it is a form page followed by a stats box. when someone enter the form, it should add 1 extra number of members in stats and when someone enter total work(1000), it should be added in the stats aswell.
