Need to code a disclaimer when linking to external sites

I am using ModX Evolution and love it! I am working on a site for a bank, and all external links need to be coded with something that pops and says your are leaving the website, do you want to continue...

Any ideas?

I think you should use a little javascript tied to all links. You could simply tie it to all <a> tags (I like jQuery) with a function along these lines

Semi pseudo code

if($(this).attr(’href’).indexOf("yourdomain.com")<0))
{
alert("Please don’t leave :-(")
}

Typical banks!

I was thinking javascript too - this one looked alright - but you should probably let your client know that it won’t work if the visitor has js disabled. How rigid they would be about that I don’t know. But I’m not sure how you could do it without javascript

I don’t know how they do it, but deviantart.com has this type of thing. If you click on an outgoing link it takes you to an in-between page - see here: http://www.deviantart.com/users/outgoing?www.maximumhandyman.com

Ah that’s a good idea - a bit more friendly than an alert box and will work even without js.

You could do that with a plugin that checks whether the link is external or not, and if so, passes the link to a snippet on the ’in between’ page. On that deviantart site they’ve passed the link to the intermediate page via url parameter:

Did you get anywhere with this? I have a plugin+snippet combination working if you still need it... works the same as deviantart.com

I would be interested in your solution, I haven’t started working on this yet.

Unfortunately, it is an FDIC guideline:

Per the Interagency guidance “Web-linking: Identifying Risks and Risk Management Techniques” issued April 23, 2003, the customer must be given the opportunity to accept or decline leaving the bank’s website.

I saw that one but wasn’t sure what to do with this line, if anything:


And, do I just drop this code in everywhere I have an external link?

Sorry, I’m not much of a coder (just enough to be dangerous).

I guess the author intended it for Drupal, you could remove that line (along with the closing brace ’}’ at the end of the script).

My solution will work even if the user has js disabled, which I guess is preferable given the rigid guidelines you’re working with. I’m in the middle of something now but will try to post it for you later today or tomorrow...

Sorry, have been a bit busy the last few days. Never a bad thing

I'd set this up for Revo but converted it over to Evo for you. Both versions are attached. Basically, the plugin fires when a page is being loaded. It finds all links on the page and checks to see if they are external or not; if external, it is replaced with a link to your 'disclaimer' page. The snippet will be on the disclaimer page waiting to catch and display the external link, with another link back to the previous page.

Please note that if the external link does not begin with a valid url scheme such as 'http', 'https', 'ftp', 'file', or 'mailto' it will not be recognised as an external link and the user will end up on your 404 page. See below if you need to add more schemes.


Setup instructions:

snippet.exthref.php
Create a new snippet called 'extHref' and paste the contents of the file provided.

Create a new document for your 'disclaimer' page. Paste in the following snippet call where you want your links to appear:

Where 'linksTpl' is the name of a chunk you will create in the next step.

Create the chunk 'linksTpl' containing something like this:

Note- you can change the markup to whatever you need, just note the placeholders [+back+] (previous page) and [+link+] (external link).


plugin.exthref.php
Create a new plugin called 'extHref' and paste the contents of the file provided.

Scroll down to...

...and change '1' to the id of the disclaimer page containing the extHref snippet call.

If you need to add more link schemes, add them here:


Before saving the plugin, click the System Events tab and check the box next to 'OnWebPagePrerender'.

And... that's it. Hope it makes sense and let me know if you have any issues.

Edit - download links were broken. I've re-uploaded the files, but can't remove the original links. Use the bottom two. [ed. note: okyanet last edited this post 10 years, 9 months ago.]
