Undefined variable

[gapla]

I get this error:
Notice: Undefined variable: output in c:\archivos de programa\apache group\apache\htdocs\agenda\php-calendar-0.8\php-calendar\includes\display.php on line 137

Some help?

Insufficient data for a meaningful answer.

Without seeing line 137 of your script its impossible to say.

This is line 137

 $output .= "<div id=\"content\">"

and some code around :

if($i == 0) {
		$output .= "<div id=\"content\">"
		. "<h1>"._('No hay eventos para este día.')."</h1>\n"
		. "</div>";
	} else {
		$output .= "</tbody>\n"
			."</table></div>\n";
		if($admin) $output .= "</form>\n";
	}

	return $output;
}

Do you have a line which initialized $output to some value before you concatentate into it? That could be causing your problem.

I cannot figure out where is this flaw.

Are you still getting the same error on the same line?

I don't see anything. But I also don't know what you're doing with these functions.

The only thing I see is if you don't get a row from your database $output stays uninitialized. So concatenating something in the following lines would give an error.

Try initializing $output to a zero-length string before requesting a record from the database.

ie.

$i = 0;
$output = '';
while($row = $db->sql_fetchrow($result)) {

Alternatively, as there would be nothing to concatenate if no rows are returned, change line 137 to the assigment operator '=' and not the concatenation operator '.='
