I want to update a specific field in a specific row in a database using php...

i.e. when <a href="index.html>Home</a> is clicked it adds 1 to a running tally in:
Database - exampledatabase
table - exampletable
Where row = example record
in Field = hit_count

Any Ideas?

If you link to index.html the page will just count every time it is read, so you can add the code anywhere.

<?php
 mysql_query("update tablename set field = field + 1 where condition");
?>

so:

<?php
$con = mysql_connect("localhost","USERNAME","PASSWORD");
if (!$con)
  {
  die('Could not connect: ' . mysql_error());
  }
mysql_select_db("DBNAME", $con);
mysql_query("update TABLENAME set PAGECOUNT = field + 1 where condition");
?>

Would this be right?!

It depends on your table layout.
If there is only one field, use
 update TABLENAME set PAGECOUNT = PAGECOUNT + 1

Or use your primary key.
 update TABLENAME set PAGECOUNT = PAGECOUNT + 1 where id=1

It sounds like the thing you're looking for is called a "page hit counter" and you might get better results if you used the Google Analytics web service -- instead of trying to write one yourself.

But that said, here are some resources that describe how it is done ;-)

Try first solution posted by BitFreeze in post id ID:33421505

<?php
 mysql_query("update tablename set hit_count = hit_count + 1 where examplerecord = '' ");
?>

You have only to add the correct condition to identify row wich has to be updated.

Bye

So your MySQL field has "filename" as the Primary ?
Please post the table layout.
