PHP form help

~~Rent-a-car~~ · 02-04-2008, 11:04 PM

hi well for my website i made an avatar and i want it to be used as an advertisement thing but the people who use it will be able to put their names on the avatar and i've done the code for it etc

i've got one page called index.php with a form in where someone can enter something into the box and i've got another page called avatar.php where i have the php code using $_GET to get the box name from the form and printing the text onto the image

what i want to do is stop it from redirecting to another page but have it so that when you click the button on the form the avatar appears below the form instead

the code for the index.php is here:

Code:

<html>
<body bgcolor="grey">
<center>
<form method="get" action="avatar.php">
Your Name: <input type="text" name="yourname"/>
<input type="submit" value="Get Avatar"/>
</form>
</body>
</html>

</form>
<? if($_GET["yourname"]){ ?>
<br />
avatar.php coding here
<? } ?>
</body>
</html>

I think that's what you're after? When they submit the form, the page will refresh and it will show their avatar below. Note, I've put in a <br /> so that there will be a gap after the submit button. Put in your avatar.php coding where I said so that it does the code and I presume, if your coding works, shows their image

Hey thanks for the help yes its the exact thing I want but I'm having a little trouble, because when I click the get avatar button it gives me an error saying headers have already been sent

Try closing/reopening your browser? I think that might work - even though it sounds stupid.

PHP Code:


<html>
<body bgcolor="grey">
<center>
<?php
//Put all your GET variables here
if($_GET['yourname']) {
//Your GD libary Code goes here (The output)
}
else {
?>
<!-- The actual Form -->
<form method="get" action="avatar.php">
Your Name: <input type="text" name="yourname"/> <br />
<input type="submit" value="Get Avatar"/>
<!-- End of the Form -->
<?
}
?>
</center>
</body>
</html>

Okay i got past the headers already sent error with your code --ss-- but now I'm gettign another error saying that

"The image “http://site.com/avatar/” cannot be displayed, because it contains errors."

You can't output data, then set headers.

Your going to need to make a seperate file with the GD info.

Example:

PHP Code:


<?php
header("Content-type: image/png");
$text = $_GET["text"];

// GD stuff;
?>

and

PHP Code:


<html>
<body bgcolor="grey">
<center>
<!-- The actual Form -->
<form method="get" action="avatar.php">
Your Name: <input type="text" name="yourname"/> <br />
<input type="submit" value="Get Avatar"/>
<!-- End of the Form -->

<img src="otherfile.php?text=<?php echo $_GET["yourname"]; ?>" />
</center>
</body>
</html>

When I click Get Avatar it still goes onto the other page instead of refreshing the current page
