Re: stop people trying to hack my form

Unfortunately you can't insert code in the standard BV built in form processor.

You can uncheck the "Use built in form processor" in the form properties, and insert the code (the same as the one the processor would add) adding your own custom code.

If you wish, post the code you now have, from your built in form processor, and I will modify it for you .

Re: stop people trying to hack my form

Re: stop people trying to hack my form

thanks for that, is there any danger when the file types are "xxxxxx.php.jpg"

thanks

Re: stop people trying to hack my form

Just a thought. in the properties of the upload box under validate you have the option to have only the file extensions you wish to have uploaded ie: .jpg or .png. that way if it isn't then they get the warning. I personally have this set to only except .zip as i can then scan it before opening.
