formupdate.php throws a blank page

Fike · Unread post by **Fike** » Wed Jul 25, 2012 6:39 pm

I updated my database to version 2.7.3

I have some edit forms that have more than one subform (two or three subforms), and these subforms are configured to have 30 blank rows.

When I try to save the record from these edit forms, I get a blank page and the subform records are not updated. Apparently this happens only when the subforms have many filled rows (30 or more) and many blank rows (30 or more).

The URL of the blank page ponits to formupdate.php and the source code of the blank page is the following:

It seems that the subforms have more records to update than the formupdate.php file or my server configuration can handle. Is there something I might need to configure on my php.ini file to make it work properly?

Regrads,

I've been playing with the number of rows of the subform and the formupdate.php file.

It seems that the variables $refreshAfterSave and $closeAfterSave of the formupdate.php file are throwing null values and therefore the reload function is not completed.

This only happens when the subform has many rows (more than 100), even when there is only one subform in the edit form.

My knowledge of PHP is very limited, but I will keep playing with the formupdate.php file to see if I can find out why these variables are throwing null values.

Any help will be much appreciated !

Regards,

Fike

It seems that the problem is due to my server's updated PHP. I found the answer here:

http://www.nivas.hr/blog/2012/04/04/bew ... on-option/

Now PHP limits the number of posted variables to 1000. Therefore I had to modify my php.ini file to allow more variables to be posted.

So far everything is working fine now.

Fike,

Good work.

That's what I was going to suggest.

The newer versions use a few more resources.
