RE: Scrubbing user inputs (solved)

Thanks to all your comments, we have a solution.

 

The best I’ve been able to do on the server side is remove the offending binary code, basically losing the format.

 

Using fckeditor (thanks, Dwayne) I’m back on the client side and the initial prognosis is good. The text is converted to nicely formatted html. As long as you’re remaining in a web environment, it shouldn217;t really pose any problems, but if you are to use, say Oracle Reports, to extract data from the tables and render it out as PDF, additional work may be required. Let’s keep in mind that what we’re asking it to do is retain formatting. I’d much rather deal with formatting retained as HTML instead of some pile of ascii-binary-ascii junk.

 

At Joe B’s request I reversed the process to see what would happen when I pasted html stored in the table back to MSWord. The text retrieved directly from the table (figure 1), had visible html tags. The text retrieved from the table and pasted from fckeditor back into MSWord (figure 2) looked great.

Thanks again for all the input received. You guys are great.

Again, am unsure of what your client is, or how you are accepting the input, but one idea is to use the freely available fckeditor as a javascript text area input on your forms. When you do a paste from Word to the editor, it scrubs the input, and converts it into clean HTML, so bullets still look nice, but are now in HTML. This is a tremendous tool for bringing very nicely formatted text into a text area. It is also a nice in-line web editor for direct entry as well. Application Express now has this editor built into it as one of the options for a text area.

Didn’;t mean to imply that it couldnR17;t or shouldn217;t be done in the database.&nbsp; I agree that’;s the best approach.&nbsp; I was just saying you shouldn217;t be “criticizedR21; (if that’;s even what it was) for saying you “needed” to handle this on the client.

 

 

I appreciate all giving of their time to look at this.

 

I do have access to both client and server side. Based on the responses I’ve received, I will “scrub” it server-side.

 

I thought this type of validation would normally be done client-side. That was my motivation as much as anything.

 

Have a great weekend!

I’m just guessing here, John (and James, too), but perhaps Monty will only have access to the client code, and may not pe permitted to make server-side changes.&nbsp; Not ideal, I grant you, but all too common.

 

 

Tell us a little more – what errors are you getting – error code, additional information?

What is the datatype of the parameter to your “action” procedure that processes input from the form? ; What is the datatype of the comment column in your table?&nbsp; Why do you need to handle it client-side?

 

I have used a “clean-upR21; routine that handles this server side – it removes white space from the beginning and end of the incoming data, changes non-printable characters to spaces, removes extra spaces and normalizes carriage returns and linefeeds to CRLF sequences before storing the data in the database.

 

 

Hello all,

 

I’ve built a simple html form using the pl/sql web toolkit that has a place for the user to include comments.

It’s been in production for months if not years.

 

Recently, we’ve experienced errors related to the content of the comments
and I’ve traced it to users cutting and pasting content from MS Word directly into the web form comments field.

Even that is fine except for when the user attempts to paste in bullets.

 

I’ll have to handle this on the client-side. Any ideas?

 

 

Regards,

 

Monty
