lets do some error outputting then

<?php
if (!isset($_GET['id'])) {
    // id is not set, do something
}
elseif (!ctype_digit($_GET['id'])) {
    // the id is not a valid number, do something
}
else {
    $id = (int) $_GET['id'];
}?>

Finally got it figured out:

 

<?php
$comment_id = $_GET['comment_id'];

//connect to server and select database
$conn = mysql_connect("localhost", "root", "")
    or die(mysql_error());
$db = mysql_select_db("testimonials", $conn) or die(mysql_error());

if (isset($_POST['submit'])) {

//create and issue the first query
$name=mysql_real_escape_string($_POST['comment_owner']);
$email=mysql_real_escape_string($_POST['comment_owner_email']); 
$reply=mysql_real_escape_string($_POST['reply']);
$comment_id = $_GET['comment_id'];

$error='';//initialize $error to blank
  if(trim($name)=='' ){
      $error.="Please enter your name!<br />"; //concatenate the $error Message with a line break
  }
   if(trim($email)==''){
    $error.="Plese enter your e-mail address!<br />";
    
  }  elseif (!preg_match("/^[_\.0-9a-zA-Z-]+@([0-9a-zA-Z][0-9a-zA-Z-]+\.)+[a-zA-Z]{2,6}$/i", $email)) {

        $error.="The e-mail you entered was not valid!<br />";
        
    }
    if(trim($reply)=='' ){
      $error.="Please enter your reply!<br />"; //concatenate the $error Message with a line break
  }
  if($error==''){


$sql="INSERT INTO replies (comment_id, reply, reply_create_time, reply_owner, reply_owner_email) VALUES ( '$comment_id', '$reply', now(), '$name','$email')"; 
  
mysql_query($sql,$conn) or die(mysql_error());

header('Location: testimonials.php');

  // mysql_query($sql,$conn) or die(mysql_error());
  }
    else{
       echo "<div class=error><span style=color:red>$error</span><br /></div>";
    }    
} else {

$name= '';
$email= '';
$reply= '';
}
?>
<form name="comment" id="comment" onsubmit="return validateFormOnSubmit(this)" action="reply.php?comment_id=<?php echo $comment_id; ?>" method="post">
<table border="0" cellspacing="0" cellpadding="5" width="662" class="style2">
<tr>
<td align="left"><label for="name"> Name:</label></td>
<td>
<div class="c2"><input type="text" name="comment_owner" id="comment_owner" size="30" value="<?php echo $name; ?>"/></div></td>
</tr>
<tr>
<td align="left"><label for="email">E-mail:</label></td>
<td>
<div class="c2"><input type="text" name="comment_owner_email" id="comment_owner_email" size="30" value="<?php echo $email; ?>"/></div></td>
</tr>
<tr>
<td align="left">
<label for="reply">Reply:</label></td>
<td>
<textarea name="reply" id="reply" rows="5" cols="30" value="<?php echo $reply; ?>"></textarea></td>
</tr>
<tr>
<td colspan="4">
<div class="c1"><input name="submit" type="submit" value="Submit" /> <input type="reset" name="reset" id="reset" value="Reset" /></div></td>
<td width="2"></td>
</tr>
</table>
</form>

 

Thanks for the help with this Hussam!

okay guys, the problem is solved and everything was tested and its all working fine on the server.

 

I had to change the names of the fields a little bit, I like to follow the conventions.

reply_id in the replies table was changed to id

comment_id in the user_comments table was changed to id

 

both of them are auto increment and primary key's

 

Now the problem was:

the condition on top

if (isset($_POST['submit']))

this condition  makes the page instantiate the values AFTER the submission not before.

after the submission there is no GET values.

so I added the GET value to the action attribute of the form

therefore I have the GET values anyway, if the form is submitted or not.

and that won't be a problem after the submission because there is redirection anyway.

 

the code should be like this:

 

<?php
$comment_id = $_GET['comment_id'];
//
//echo $comment_id;
//
//exit();

//connect to server and select database
$conn = mysql_connect("localhost", "webdes17_twilite", "minimoon")
    or die(mysql_error());
$db = mysql_select_db("webdes17_testimonials", $conn) or die(mysql_error());

if (isset($_POST['submit'])) {

//create and issue the first query
$name=mysql_real_escape_string($_POST['comment_owner']);
$email=mysql_real_escape_string($_POST['comment_owner_email']); 
$reply=mysql_real_escape_string($_POST['reply']);
$comment_id = $_GET['comment_id'];

$error='';//initialize $error to blank
  if(trim($name)=='' ){
      $error.="Please enter your name!<br />"; //concatenate the $error Message with a line break
  }
   if(trim($email)==''){
    $error.="Plese enter your e-mail address!<br />";
    
  }  elseif (!preg_match("/^[_\.0-9a-zA-Z-]+@([0-9a-zA-Z][0-9a-zA-Z-]+\.)+[a-zA-Z]{2,6}$/i", $email)) {

        $error.="The e-mail you entered was not valid!<br />";
        
    }
    if(trim($reply)=='' ){
      $error.="Please enter your reply!<br />"; //concatenate the $error Message with a line break
  }
  if($error==''){


$sql="INSERT INTO replies (comment_id, reply, reply_create_time, reply_owner, reply_owner_email) VALUES ( '$comment_id', '$reply', now(), '$name','$email')"; 
  
mysql_query($sql,$conn) or die(mysql_error());

header('Location: testimonials.php');

  // mysql_query($sql,$conn) or die(mysql_error());
  }
    else{
       echo "<div class=error><span style=color:red>$error</span><br /></div>";
    }    
} else {

$name= '';
$email= '';
$reply= '';
}
?>
<form name="comment" id="comment" onsubmit="return validateFormOnSubmit(this)" action="reply.php?comment_id=<?php echo $comment_id; ?>" method="post">
<table border="0" cellspacing="0" cellpadding="5" width="662" class="style2">
<tr>
<td align="left"><label for="name"> Name:</label></td>
<td>
<div class="c2"><input type="text" name="comment_owner" id="comment_owner" size="30" value="<?php echo $name; ?>"/></div></td>
</tr>
<tr>
<td align="left"><label for="email">E-mail:</label></td>
<td>
<div class="c2"><input type="text" name="comment_owner_email" id="comment_owner_email" size="30" value="<?php echo $email; ?>"/></div></td>
</tr>
<tr>
<td align="left">
<label for="reply">Reply:</label></td>
<td>
<textarea name="reply" id="reply" rows="5" cols="30" value="<?php echo $reply; ?>"></textarea></td>
</tr>
<tr>
<td colspan="4">
<div class="c1"><input name="submit" type="submit" value="Submit" /> <input type="reset" name="reset" id="reset" value="Reset" /></div></td>
<td width="2"></td>
</tr>
</table>
</form>

 

not very clean but tested and working!

 

good luck!
