Question

I want to make a code that counts the click on the link which is on my website and adds 1 to the LINKCOUNT row in the mysql database, but im having trouble over coding.

This is my code when I click the LINK on my website:

mysql_connect("localhost", "123", "123") or die(mysql_error());
mysql_select_db("123") or die(mysql_error());

$result = mysql_query("SELECT id, sitename FROM links WHERE siteurl = \"www\"");
$row = mysql_fetch_array($result);

mysql_query("INSERT INTO links (linkcount) VALUES  $row['linkcount']");
$count = 0;

Not sure if that is right way of doing it, any ideas what the code will be?

EDIT

I can now add 1 to the LINKCOUNT row but every link i click adds to the same row, i need each link to have seperate row and click count.

Try this query:

UPDATE `links` SET `linkcount` = `linkcount` + 1 WHERE `siteurl` = 'www'

And about your code: your query doesn’t select the linkcount column, so $row['linkcount'] is always null.

EDIT:

If your table doesn’t contain rows for every link you want to track, you should use that kind of code:

mysql_query("UPDATE `links` SET `linkcount` = `linkcount` + 1 WHERE `siteurl` = 'SITE_URL'");
if(mysql_affected_rows() == 0)
    mysql_query("INSERT INTO `links` (`sitename`, `siteurl`, `linkcounter`) VALUES ('SITE_NAME', 'SITE_URL', 1)");

You have to insert proper SITE_NAME and SITE_URL
