I have a date field in a MySQL database which is set to accept NULLs. If I enter a record from phpMyAdmin and leave the date field blank, the record is entered properly. However, if I do the same thing from a form, I get an error that the date cannot be blank. It seems that I need to enter a NULL in the date field from the form rather that nothing. At the suggestion of someone on a newsgroup, I added the following line: if ($date === '' or !isset($date)) $date='NULL'; This almost works, but the resultant statement contains the single quotation marks, which cause an error. INSERT INTO jobs ( JobNumber, DateRcvd, DateEff ) VALUES ( '9999', 'NULL', 'NULL') Does not work, but INSERT INTO jobs ( JobNumber, DateRcvd, DateEff ) VALUES ( '9999', NULL, NULL) does. This is my actual query: $query = "INSERT INTO jobs ( JobNumber, DateRcvd, DateEff, ) VALUES ( '$JobNumber','$DateRcvd','$DateEff',)"; If I remove the single quotes from the date values, the nulls are entered correctly but that only works if the field is null. If a date is entered, it doesn't work. Ahy help will be greatly appreciated.
