Try like this in sql query  It will work fine    sql  UPDATE create test set url     POST url   WHERE test name   test name       If you have to update multiple columns  Use like this    sql  UPDATE create test set  url      POST url    platform     POST platform   WHERE test name   test name

You have to have single quotes around any VARCHAR content in your queries  So your update query should be   mysql query  UPDATE blogEntry SET content     udcontent   title     udtitle  WHERE id    id      Also  it is bad form to update your database directly with the content from a POST  You should sanitize your incoming data with the mysql real escape string function

you must write single quotes then double quotes then dot before name of field and after like that  mysql query  UPDATE blogEntry SET content      udcontent     title       udtitle    WHERE id       id

First  you should define  doesn t work   Second  I assume that your table field  content  is varchar text  so you need to enclose it in quotes  content      content   And last but not least  use echo mysql error   directly after a query to debug

Without knowing what the actual error you are getting is I would guess it is missing quotes  try the following   mysql query  UPDATE blogEntry SET content     udcontent   title     udtitle  WHERE id     id
