How do i remove this error from my code:Notice: Undefined offset: 2 in C:\wamp\www\im

Hey.

In this case, the warning is being shown because the explode call is not creating the third (offset: 2) element that your list call is expecting. That, in turn, means that your $date format is invalid.

The best way to fix this is to verify that the $date is valid by counting the elements before trying to use them (see count()). Make sure all three elements exist, and if not, either trigger a warning or use a default value.

Thanks so much for the prompt reply.
Please, what exactly should i change in the code so that it will stop displaying those errors.

You need to replace line #25 with code that explodes the $date into a variable and counts the elements in the variable. If it counts 3 elements, proceed with the code. If not, you need to either:

Use a default value.
Try to "guess" the real value.
Bail out with an error.

I would start with #3 and work my way up to the others.

Try it; see how it goes. If you run into trouble, post your attempts here and we will try to guide you in the right direction.

i tried using the mktim() function but it generated more errors.
i just need a quick way to fix this so that the errors stop showing on the web browzer.

Code:

function format_date($date){
         list($yyyy, $mm, $dd) = split("-", $date);
         $day[] = split(' ', $dd);
         $date = date('F jS, Y', mktime(0,0,0,$mm,$day[0],$yyyy));
         //echo("<br><br>Now: " . $date);
         return $date;

If you just want the warning to disappear then you could prefix the list call with a @ char. Note that this does not fix the problem! It just hides the error message.

i tried using the mktim() function but it generated more errors.

I didn't notice it before, but your use of the time function on line #27 of the code in your first post is incorrect. The time() function takes no parameters. - It ONLY returns the current timestamp. You can not use it to construct a timestamp from arbitrary data.

You should be using the mktime function, like you posted in your last post. It generates errors because - like with the other warning - the date data you are feeding it is invalid.

All of this can be fixed by following the instructions I posted in my last post.

Thanks so much for your assistance. i had to hide all my errors for quick deployment.
Yet i still need more assistance.
i want to display my images one after the other such that the viewer will be able to click next and previous from different albums.

the following code only displays the images in a table format on the same page.

Code:

<?php
      // Retrieve albums from database
      $sql = "SELECT photos.photo_id, photos.photo_title, photos.photo_desc, photos.photo_date, photos.photo_location, photos.thumbnail_location FROM photos WHERE photos.album_id = " . $_GET['album_id'];
      $result = @mysql_query($sql) or die("Error retrieving records from the database: " . mysql_error());

      $i = 0; // Row counter

	   while( $row = mysql_fetch_assoc($result))
	   {
	   		$data[] = $row;
	   }
	
	   $count = ( ceil( count( $data ) / IMAGE_DISPLAY ));	

	
	   for( $i = ( int )0; $i < $count * IMAGE_DISPLAY; $i++ )
	   {
        	if ( ( $i % IMAGE_DISPLAY ) == 0 && ($i != 0))
        	{
        		echo("</tr>\n<tr>");
        	}  	
        	@$photo_date = format_date($data[$i]['photo_date']);	
        	if ( @$data[$i]['photo_location'] )
        	{
        		echo("<td valign=\"top\" width=\"" . floor(100 / IMAGE_DISPLAY) . "%\"><p><a href=\"view_photo.php?photo_id=" . $data[$i]['photo_id'] . "\"><img src=\"" . $data[$i]['thumbnail_location'] . "\" title=\"Photo Date: " . $photo_date . "\" align=\"center\"></a>");
                echo("<br /><p>Photo Details: " . $data[$i]['photo_desc'] . "<br />Date: " . $photo_date . "</p></td>\n");
        	}
        	else
        	{
        		echo("<td valign=\"top\" width=\"" . floor(100 / IMAGE_DISPLAY) . "%\">&nbsp;");
        		echo("</td>\n");
        	}     	
        }
?>

Please what do i need to do to display the images one by one?
Thanks
