html - How to get a div class to be displayed on certain pages using a template and php -


i have template web pages want div class not seen on pages. use url content out of database php example of url = index.php?categorie=navigatie_bar&onderwerp=startpagina

i need code catagory url , if catagory not navigation_bar 

 echo '<div class"fb-comments"></div>';

can ?

        <div id="container">         <div id="pagina_text">                      {{ content }}                     </br>                     <div class="rw-ui-container"></div>                     </br></br>                     <?php                         if(strcmp($_get['categorie'], "navigatie_bar") != 0)                         {                         echo '<div class="fb-comments" data-href="http://alledaagsetips.nl"  data-numposts="10" data-colorscheme="light"></div>';                          }                         ?>         </div> <!-- end pagina_text -->         </div><!-- end container -->

you can access url variables via $_get['name_of_parameter'].

if(strcmp($_get['category'], "navigation_bar") != 0) {   echo '<div class="fb-comments"></div>';  }

in case, if index.php?category=navigation_bar div echoed.

take attention spelling, in example wrote catagory instead of category

edit: can $_get['category'] == 'navigation_bar', string comparisons safer use strcmp (string compare) function. see string comparison using == vs. strcmp

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
