PHP query inserts 2 rows into the table - php

Question

OK, here is the deal. I have 3 queries putting data in different tables. 2 of them are in included files. I've tried to put them into the main code, the result was the same. The first two queries inserts one row with the data and a blank row. The third works fine. Here is the code.
This in the main page:
<? $p=0;
if ($select2)
{
$event=$select2;
}
else
{
require_once("insert_gal_name.php5");
}
if ($select)
{
$folder=$select;
}
else
{
require_once("insert_folder.php5");
if (file_exists("Connections/".$folder))
{
}
else
{
mkdir("Connections/$folder",0777);
}
}
while($p<$number)
{
$p++;
$dir = 'Connections/'.$folder.'/'; // Директорията в която ще се записват файловете
copy($_FILES['file']['tmp_name'][$p],"$dir".$_FILES['file']['name'][$p]); //Копиране на файла
echo "Файлът бе качен успешно!<br>"; // Извеждане на съобщение показващо, че файла е качен
if($_FILES['file']['name'][$p])
{
$real_file_name = $dif_of_files.$_FILES['file']['name'][$p];
$nom_file = str_replace(" ", "", $real_file_name); }
$query = "INSERT INTO gallery (name, title, day, month, year) VALUES ('$nom_file', '$event', '$day', '$month', '$year')";
$result = mysql_query($query) or die(mysql_error());
}
if (!$result)
{
echo "Error";
}
else
{
echo "All data was uploaded successfuly.";
}
?>
And here are the includes in the order they are placed in the source
<? $query = "INSERT INTO gallery_names (name) VALUES ('$event')";
$result = mysql_query($query) or die(mysql_error());
if (!$result)
{
echo "Error";
}
else
{
echo "The gallery was created successfuly.";
}
?>
<? $query = "INSERT INTO folders (name) VALUES ('$folder')";
$result = mysql_query($query) or die(mysql_error());
if (!$result)
{
echo "Error";
}
else
{
echo "The folder was created successfuly.";
}
?>

Answer 1

<?
if($event!='')
{
$query1 = "INSERT INTO gallery_names (name) VALUES ('$event')";
$result1 = mysql_query($query1) or die(mysql_error());
if (!$result1)
{
echo "Error";
}
else
{
echo "The gallery was created successfuly.";
}
}
?>

Answer 2

If $select2 is false then this code will do two inserts. If $event is empty one of these will be an empty row which sounds like the problem you're having.
What are the values of $select2 and $event? Have you tried debugging them?
