Value carry over hits limit??

[Anon]

Recently i'm writing application for a financial institution for online databse. This application itself contains lots of form with lots of value... i'll say each page submit is about 300-500 value. And i found that i've problem carry the value from page to page... for example.. http://www.abc.com/abc.php?a=1&b=2&c=3&...&n=x

When i submit this form... and when i use header to redirect it... carry with all the value.... it will lead me to "This page can not be displayed". This problem also happen when i process a lot of data connection with MySQL... after doing a lot of data input or output, and the header doesn't work. I'm wondering any expert could explain why this happen and suggest me a better way to write this type of program? Thank you very much.

The problem is probably with your URL.
http://www.abc.com/abc.php?a=1&b=2&c=3&...&n=x

There is a character limit to the length of a URL. I can't remember exacly what it is, 128 I think, but don't quote me on that.

You are going to have to find another way to pass your data between pages. Do you know the difference between a form GET and POST method? Well change your form deffinition so that it looks like this:
<form method="post">

This means the values won't be sent to the server using the URL, and you don't have a character limit. You other method would be to use PHP sessions. Read up on them in the PHP manual. Then all you would have to do is pass the session ID.
