MySQL & PHP

Ok if I wanted to create an update form for a page that has been published to the web already, how would i go about doing it so that when a user clicks on update form, enters values that the values entered can be part of the update action.

can i declare like $textbox1 = textbox1.text

then do like mysql_query("UPDATE `tablename` SET field2='$textbox1' LIMIT 1");

that code should work just fine

Use the $_GET or $_POST arrays to access form data. For an update form, you should be using POST. Also, ensure that you escape data before inserting it into a SQL query, or your data is exposed to arbitrary attack via SQL injection.

$value = $_POST['fieldname']
# ...
mysql_query("
  UPDATE tablename
  SET field2='".mysql_real_escape_string($value)."'
"); 

The LIMIT clause is usually unnecessary, but you should have some other way of identifying the row you want to update. Usually a primary key is used here.
