Help debugging client having problems with site

[JRS]

Hi,

 

Strange problem - My site allows users to register their client contact details on the site. One user when he tries to register his customers - randomly certain customers don't get registered, while others get registered. If the client tries to re-enter these particular

data - nothing happens.

 

If he sends me the data and I try it - I am able to enter the data without any problems. I've also tried from a system with the

same OS & Browser as the client - still no problems for me.

 

My site is built using PHP 4.4.8 & MySql 4.1.22 - standard

 

My question is has anyone experienced a similar situation, where a client is unable to enter data on a site - and others have no problem interacting with the site. If so what caused the problem.

 

Another question is what would be a good way to debug this type of problem?

 

Thanks in advance

JRS

Hi l0ve2hat3,

 

The code is quite large - didn't want to waste people time muddling through it.

Basically it's a form - form fields are processed using $_POST and the data is verified and then inserted into a mysql db.

 

As I mentioned it appears to work without a problem on various systems - except for this 1 system: running Vista & IE. Some

records are not being inserted.

 

I am thinking of adding some sort of logging mechanism and ask him to enter data and write everything to a file and see what is

going on with the system.

 

Thanks for your reply

yeah i understand but no one is going to help with code to look at.  php doesnt care what browser your using for the most part so it must have something to do with the html/javascript. unless your using cookies?
