 * Hello Tobias, thank you for the awesome extension. I understand that there are
   character sanitations with the Get Parameter extension, however the && logic 
   operators do not get passed even after adding the & symbol as mentioned in the
   other threads.
 * Is there any lines of code that I could add into the plugin to pass through the
   logic operators available in the row filter?
 * Thank you for the help!
    Frank

 * Hi,
 * thanks for your post, and sorry for the trouble.
 * Could you clarify which modifications you made to the files? Thanks!
    It might
   be necessary to also allow the semicolon `;`, as a `&` in a URL usually gets 
   encoded as `&`.
 * Regards,
    Tobias

 * Hello, no trouble at all. Thank you for the help!
 * I edited the file tablepress-shortcode-filter-get-parameter.php
 * $filter_term = preg_replace( ‘#[^a-z0-9 &;]#i’, ”, $filter_term );
 * I then tested the get parameter URL with parameters like
 * [https://example.net/test/?table_filter=1&&b](https://example.net/test/?table_filter=1&&b)
   
   [https://example.net/test/?table_filter=1&&b](https://example.net/test/?table_filter=1&&b)
 * It appears that only the string before the symbols are accepted, and the && and
   anything following is completely disregarded.
 * Thank you!

 * Hi,
 * ah, now I see what’s happening. The problem here is that the `&` character in
   a URL has a special meaning. It’s the separator between multiple query variables
   in the URL.
 * We might therefore have to “url encode” it, so that it’s not recognized as a `&`
   in the URL.
    For that, please try again with `https://example.net/test/?table_filter
   =1%26%26b`
 * This might mean that you have to allow the `%` as well, and it might be necessary
   to add a line like
    `$filter_term = urldecode( $filter_term );` after that `preg_replace`
   line.
 * Regards,
    Tobias
