Hi folks, I have a couple of text boxes on my website (for comments, correspondence, etc). I have been inundated with spam (obviously copied and pasted text - tons of links and text). I have placed a code on the page which limits the number of characters that can be TYPED but it's not stopping the copy & paste command.

I have disabled the right click option also but that still is not the answer, so is there a way to keep text from being pasted into a textarea/input type box?

Thanks

Well rather than do that, you can make it so when they click "submit", it turnicates text that is over a certain point. This is of course, much more effective than limiting what they can type.

This disables F5.

All you have to do is change the key code to the key code for control & v.

However what 404 said makes more sense.

Thanks 404, how is that done?

In PHP, while working with fopen(), fwrite(), and fclose() you can set a limit to how much is written. Give those pages a read and you can probably figure it out.

Thanks for the advice all

PHP Code:

$_POST['userinput'] = substr($_POST['userinput'], 0, 15); //Only allow first 15 chars.

Hi MMJ, where would that code be placed? Sorry folks, you're working with an unknowledgable person here.

Anywhere, just change userinput to whatever you have the input box called.

e.g. input box: <input type="text" name="input">
code: $_POST['input'] = substr($_POST['input'], 0, 15);

Thanks, I'll give it a try

Most likely this is how your spam is being posted. There are bots out there that hunt for FORMS, they look for TEXTAREA's and populate and submit. Best way to get rid of these nasty bots is to add a CAPCHA to your form submit. This is one of those things that makes the user put in the letters and numbers before they submit. Another way to eliminate them is to scan for HREF in your submitted text and then ignore the entire message. This will also eliminate anybody trying to link to their own website, or others. Whatever you feel is the best implementation.

Well there are commercial options, but who likes to pay
With most web development languages take a look at the developers add on or exchanges.
Most likely you can pick up an addon or extensions for free, or if you cant find one for the development environment you like working in, look for addons that can generate images based on text. You can create your own capcha routine that way.

Thanks rick, I was checking out a free CAPCHA a few weeks ago for that very purpose. Can't remember why I never installed - terrible memory
