A regexp like this should work: /^([a-zA-Z]|\s)+$/ Cheers, Andy Ladouceur Andy Amol wrote: Hi, I would like to test whether a given sting contains only character, it should also support spaces. eg "Course Book String".

Hi, I would like to test whether a given sting contains only character, it should also support spaces. eg "Course Book String". I am able to test "CourseBookString".

[PHP-DB] Re: Double Submission into DB if Hit Refresh

You can make it even more easy for inserts by using the SQL command IGNORE. Just make the column with the unique transaction ID your primary key or (if you don't use a auto-increment column) make your id column the primary key and use: INSERT IGNORE INTO table ... So the record is only inserted if the primary key doesn't exist yet and just ignores multiple inserts with the same id. This should work for MySQL - I don't know if it works for other DBs as well. I don't see a problem for multiple updates as the data usually won't change between the refresh.

[PHP-DB] Storing route in DB
Hi, I am not sure if my issue can be partially solved by a good database design or that all stands or falls with the application. If I have a bunch of locations in a table and I want to describe a route between a number of these locations, what's the best way to do it, considering that it must be possible to change the route afterwards. For instance (A-B-C-A, becomes A-C-B-A). Ofcourse it's not a really big problem to solve in PHP. However I believe it would be best if the database enforced some rules about how a route may look. For instance no matter what any user or application does, it should not be possible to store a route that looks like A-B-B-A or like A-B- -A or lose all route information when there are still bookings. Logically the problem is not too difficult, however I am looking for a way to implement this in MySQL/PHP. Any pointers to help me in my analysis would be much appreciated.
