i echoed it

But still the problem is there

I tried nothing wrong, just that you haven't *printed* it on screen!

Code:

<?php 

    $name = $_POST["txt_name"];
	$email = $_POST["txt_email"];
	$comment = $_POST["txt_comment"];
	echo $name;
	echo "<br>";
	echo $email;
	echo "<br>";
	echo $comment;
	echo "<br>";
?>

<html>
<head>  
<title> Guest Boook</title>
</head>
<body>
 <form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="POST">
 <center>
 Name : <input type="text" name="txt_name"> </input>    
 Email : <input type="text" name="txt_email"> </input>
 <br>
 <br>
 Comment
 <br>
 <textarea name="txt_comment" style="width : 75%" rows=10" ></textarea>
 <br>
 <br>
 <input type="submit" value="Submit"> </input>
 </center>
 </form>
</body>
</html>

So u think Wamp is the culprit???

most probably. Some other setting you've changed on php config must be getting in the way. Especially since it says something about "index"

what im furious is that this was working just fine!! no errors!! but suddenly this happend!

kosandpol · May 6, 2009

another thought, what test data did you enter as name to check this script ?

sri_lion · May 6, 2009

Ok, create a new folder inside the root, copy paste this file only and name it as "index.php" and try to run from there!

If possible restart Apache before that!

ohhh

the problem comes when i run the script

But when i actually input data and Submit they are nicely replaced... so what i should do is actually check whether variable actually contains data

what the best way to do it???
will strlen work??

sri_lion · May 6, 2009

Here's on my localhost it works, I'm using XAMPP though!

It should. A sanity check to see if the variable has any data before assigning is pretty much a standard in good programming.

Ranhiru · May 6, 2009

Yeah as i see when the first time i run the page the error comes... but when i press the submit button WITHOUT any data ,the errors disappear... and with data it works, like it should work

Ranhiru · May 6, 2009

Code:

<?php 
[COLOR=Red]
    $name = $_POST["txt_name"];
    $email = $_POST["txt_email"];
    $comment = $_POST["txt_comment"];[/COLOR]
    
    if (strlen($name) > 0)
    echo $name;
    
    echo "<br>";
    
    if (strlen($email) > 0)
    echo $email;
    
        
    echo "<br>";
    
    if (strlen($comment) > 0)
    echo $comment;
    
    
?>

i did a check but still the errors are pointing as soon as i run the page...and they are pointing @ the lines in red... and as soon i do a submit the page runs fine...without any error!

Ranhiru · May 6, 2009

Code:

    @$name = $_POST["txt_name"];
    @$email = $_POST["txt_email"];
    @$comment = $_POST["txt_comment"];

i hid the error messages so its not outputting the errors.... but hithata madi wage

because i dunno what causes the error in my machine!

Have you tried what I suggested earlier copying the file into a new directory?

Nope

The error remains

But adding a @ before the coding suppresses the output of errors.. so the code LOOKS like it is working fine...
