the problem here is you are making single insert with entire url data .
1) first identify each url value from text area and make an array of it using explode with '.' or specific keyword .
2) loop through the size of url array to insert into the table.
while inserting check error on mysql object in error occurs exit otherwise keep on inserting till all insertion is done.
suppose you have all urls in $url= $_POST[url]; with '\\n' seperate then:
$urlArr = explode("\n",$url);
for($i=0;$i< sizeof($urlArr);i++){
$sql="INSERT INTO link (url, cat_id) VALUES ('$url[i]' , '$cat_it')";
if (!mysql_query($sql,$con))
{
die('Error: ' . mysql_error());
}
}
and please start using PDO or mysqli.
