Question

I am having problems with the following code, it seems to work and creates the records just fine, the problem is each time I hit submit, instead of it updating the record it just creates a new one. If I turn off auto incremental for the primary key it updates the record just fine but then doesn’t create any new ones, it seems either one or the other :-S

<?php
 $query = mysql_query("
  INSERT INTO hqfjt_chronoforms_data_emailform 
   (cf_id,cf_uid,emailformname,datesent)
  VALUES
   ('$_POST[cf_id]','$_POST[cf_uid]','$_POST[emailformname]','$_POST[datesent]')
  ON DUPLICATE KEY UPDATE
   datesent='$_POST[datesent]';
 ") or die(mysql_error());
 ?>

Answer 1

did you already try to echo your query string? guess the variable replacement inside it is wrong. try something like that for debugging:

<?php
 $sql = "INSERT INTO hqfjt_chronoforms_data_emailform 
   (cf_id,cf_uid,emailformname,datesent)
  VALUES
   ('{$_POST['cf_id']}','{$_POST['cf_uid']}','{$_POST['emailformname']}','{$_POST['datesent']}')
  ON DUPLICATE KEY UPDATE
   datesent='{$_POST['datesent']}'";
 echo $sql; // for debugging
 $query = mysql_query($sql) or die(mysql_error());
 ?>

Note the corrected variable names above. (curly braces around it, quotes around the array index)
