The script is written to populate a postgresql database table using an html form but it is giving me the error below.

Warning: pg_query() [function.pg-query]: Query failed: ERROR: type "nextval" does not exist LINE 1: ...type,crop_name,local_name, cultivation_yrs)VALUES(nextval('c... ^ in C:\ms4w\Apache\htdocs\php\inputcrops.php on line 22

I imagine there should be a comma following the nextval() call.

Hey I dont know anything about postgresql database but the query line is quite interesting
$query = "INSERT INTO crops (cropid,crop_type,crop_name,local_name, cultivation_yrs)VALUES(nextval('cropid_seq') '$crop_type', '$crop_name', '$local_name', '$cultivation_yrs')";
you have used nextval function. Make sure this function does exists in postgresql database(I guess it does not). another strategy you can apply to figure out the bug

  1. $query = "INSERT INTO crops (cropid,crop_type,crop_name,local_name, cultivation_yrs)VALUES(nextval('cropid_seq') '$crop_type', '$crop_name', '$local_name', '$cultivation_yrs')";
  2.  
  3. echo "<br>".$query."<br>";
  4.  
after that run the browser and run the site. then from browser copy the query. Then run it from the database client. You will get more information about your error and also be able to figure out what is happening faster.
