PHP Postcard Notice: Undefined index: Notice: Undefined variable errors


Recommended Posts

hi,

I need help really badly for my PHP-Postcard Script. Basically it sends the card out but the URL does not work, I get the following error message:

 

The URL is not valid and cannot be loaded

 

It also states that

Notice: Undefined index: www.voluntary.awardspace.co.uk in /home/www/voluntary.awardspace.co.uk/Postcard.php on line 25

Notice: Undefined index: Postcard.php in /home/www/voluntary.awardspace.co.uk/Postcard.php on line 25

 

See Code below:

 

<?php

session_start();
//check error log
ini_set('display_errors', 1);
ini_set('log_errors', 1);
ini_set('error_log', dirname(__FILE__) . '/error_log.txt');
error_reporting(E_ALL);

// CHANGE PARAMETERS HERE BEGIN
$senderName  = " Holidays From Home "; // Eg.: John's Postcards
$senderEmail = "chris01@voluntary.awardspace.co.uk";  // Eg.: john@postcard.com
// Change only if you have problems with urls
$postcardURL = "http://".$_SERVER["www.voluntary.awardspace.co.uk"].$_SERVER["Postcard.php"];
// CHANGE PARAMETERS HERE END
$result = 0;
$msg = "";
$msg1 = "";
$pic = "";
function displayPhotos()
{
global $pic;
$columns = 5;
$act = 0;
$act1 = 0;
// Open the actual directory
if($handle = opendir("thumbs"))
{
  // Read all file from the actual directory
  while($file = readdir($handle))
  {
   if(!is_dir($file))
   {
    if(isset($pic[1]))
    {
     if($pic[1] == $act1){$sel = "checked";}
     else{$sel = "unchecked";}
     }
    if($act == 0){echo "<tr>";}
    echo "<td align='center'><img src='thumbs/$file' alt='postcard'/><br/><input type='radio' name='selimg' value='$file,$act1' $sel/></td>";
    $act++;
    $act1++;
    if($act == $columns){$act = 0;echo "</tr>";}

       }
    }
  echo "</tr>";
  }    
}

Absolutely any help would be much appreciated. I want ot know is there a way round this problem?

 

Here is the http://voluntary.awardspace.co.uk/Postcard.php

 

I am absolutely desperate to solve this burning issue  :(

 

You're getting these errors because the key indexes you are using don't exist within the $_SERVER array.

 

$postcardURL = "http://".$_SERVER["www.voluntary.awardspace.co.uk"].$_SERVER["Postcard.php"];

 

It should be:

$postcardURL = 'http://www.voluntary.awardspace.co.uk/Postcard.php';

:'(

 

No that unfortunately didn't work at all i get new error messages here:

I really am very confused by this :shrug:

Hi

 

Suspect the variable it is complaining about is $file which is set up outside the function then utilised inside the function. As $file isn't declared as Global in the function it knows nothing about it.

 

Suspect the indexes it complains about are the ones in the $_POST array, and if you go directly to this page you probably haven't passed a form in with these set, hence they are undefined.

 

All the best

The problem with $sel is that it is only defined IF $pic[1] is defined, which it is NOT.  $pic is defined as an empty string, and passed to the function via a global.  Nowhere is $pic changed to an array, nor populated by anything.

 

The email, and message indexes, are coming from the $_POST array.  There is no check to make sure those variables are defined before working with them.

I understand what you mean about $pic but I am unsure as to how to fix it here is line 52:

echo "<td align='center'><img src='thumbs/$file' alt='postcard'/><br/><input type='radio' name='selimg' value='$file,$act1' $sel/></td>";

 

In that where would define $pic as a array?

 

Line 134-5

<tr><td>Send to (email address):</td><td><div style='color:#f00;font-size:16px;'>$msg1</div><input type='text' name='email' size='30' value='".$_POST["email"]."' /></td></tr>

          <tr><td>Message:</td><td><textarea name='message' rows='10' cols='40'>".stripslashes($_POST["message"])."</textarea></td></tr>

 

From that It looks to me like it is passing the data through but obviously not.

 

 

You are defining $pic on line 19 as an empty string.

 

Line 22: You are calling a global on $pic to include it into the function displayPhotos();

Line 34: Is the next time you are calling $pic.  You are asking it if $pic[1] (array) is set <= which will fail everytime as $pic is an empty string.

Line 36 & 37: defines $sel, as this if loop on $pic[1] will always fail due to $pic being an empty string, and not an array, then $sel will NOT be defined.  Thus the errors.
