Bad links domain.com/" How to strip html characters?

[bugauto]

There are people clicking bad links to my site. The links contain html characters in the url. Examples are below.

mydomain.com/"http://www.mydomain.com/dir/img.jpg"

some how there browser is rendering whats inside of an input text tag.

example input text tag on my site is

<input type="text" value="<a href=&quot;http://<?php echo $site_url . $site_page; ?>&quot; target=&quot;_blank&quot;><img src=&quot;http://<?php echo $site_url . $urlpath. $file; ?>&quot;</a><br><a href=&quot;http://<?php echo $site_url . $site_page; ?>&quot;><?php echo $cat_no_symbols; ?>Comments at <?php echo $site_name; ?></a><br>">

How can I use htaccess to make sure their browser does not render what's in the input tag?

You can't use htaccess to fix this, you need to fix the links on your pages. If there are similarly-broken links from other sites, they can be fixed-up in .htaccess, but the links on your own site must be correct to avoid a "google-disaster."

I'm no PHP expert, but that code looks broken in several places. You might consider 'building' the entire <input> line, and then outputting all of it with a single php echo. To embed a quote in your string, escape it with a \ character, like this: \"
