Form page acting funny!

**Daryl** · 09-21-2007, 10:48 PM

Hey, can anybody tell me why this scrip isn't working? I'm sure the code is right, but when the page is opened in a browser, the php code is filled it the text field. Also the php code shows up in the html source code (?). I'm using Wordpad as my text editor and saving my files as text files with a .php extention (my_file.php). Can anyone help?

<body>
<h1>Reverse String</h1><hr />
<?php
if (!isset($_GET['input_text']))
echo "<p>Enter the string you want to reverse.</p>";
else{
$ForwardString = $_GET['input_text'];
$ReverseString = strrev($ForwardString);
echo "<p>'$ForwardString' spelled backwards is '$ReverseString'.</p>";
}
?>
<form action="ReverseString.php" method="get" enctype="application/x-www-form-urlencoded">
<p><input type="text" name="input_text" size="20" value="<?php if (!empty($_GET['input_text'])) echo $_GET['input_text'] ?>" /></p>
<p><input type="submit" value="Reverse String" /></p>
</form>

Do you have a link to the page?

Yeah, here's the address:

You might want to check with your host to make sure it supports PHP.

Indeed, this looks that that is the case. If they say they do support PHP, make a new file called info.php and place this in it:

Code:

<?php
 phpinfo();
?>

if you get a blank page, then they are lying. Otherwise, further troubleshooting will be required.

That's what I thought at first. But my previous and simpler scrips were working fine. I already contacted my web host (Bravenet) and the said PHP was working fine. I also tried the code on another server (Go Daddy) and got the same results...the simpler scrips work but the ones with forms don't. This is really gettin' frustrating!

**Daryl** · 09-21-2007, 11:24 PM

Btw, I DID try the code you gave me and it worked. I got to the PHP info page.

Ok, then you will need to post the entire code for the page so that we can see what is the cause of your problem. Be sure to remove any usernames and passwords.

I really appriciate you checking it out!
Here's my code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtmll/DTD/xhtmll-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Logical Examples</title>
</head>
<body>
<h1>Reverse String</h1><hr />
<?php
if (!isset($_GET['input_text']))
echo "<p>Enter the string you want to reverse.</p>";
else{
$ForwardString = $_GET['input_text'];
$ReverseString = strrev($ForwardString);
echo "<p>'$ForwardString' spelled backwards is '$ReverseString'.</p>";
}
?>
<form action="ReverseString.php" method="get" enctype="application/x-www-form-urlencoded">
<p><input type="text" name="input_text" size="20" value="<?php if (!empty($_GET['input_text'])) echo $_GET['input_text'] ?>" /></p>
<p><input type="submit" value="Reverse String" /></p>
</form><hr />
</body>
</html>

I can't figure it out. I used the code you posted and it worked perfectly on my servers. I didn't modify anything and it worked fine; so that means the code is code (other than the XHTML standard you are using; which Twey can explain more about this). As for the PHP, there is nothing wrong with it as I tested on several servers and it worked fine.

Sorry I couldn't be of more help.
