How do I declare a variable in PHP without displaying its value in my html? -


i working in wordpress website , need pass url of page argument of function. in case using

bloginfo('url');

to retrieve base url of site.

so code is

<?php   $portfolio_link = bloginfo('url');  if ( ! function_exists( 'ow_nav' ) ) {     function ow_nav( $nav_position ) {         ?>         <nav id="ow-nav-<?php echo $nav_position; ?>" class="ow-nav clearfix ow-nav-<?php echo $nav_position; ?>">             <ul class="ow-nav-list">                 <?php ow_nav_item( '#home',         'home'                ); ?>                 <?php ow_nav_item( '#about',        'about'               ); ?>                 <?php ow_nav_item( '#criteria',     'investment criteria' ); ?>                 <?php ow_nav_item( '#approach',     'approach'            ); ?>                 <?php ow_nav_item( '#team',         'team'                ); ?>                 <?php ow_nav_item( $portfolio_link, 'portfolio'           ); ?>             </ul>         </nav>         <?php     } }  if ( ! function_exists( 'ow_nav_item' ) ) {     function ow_nav_item( $link, $text ) {         ?>         <li>             <a href="<?php echo $link; ?>">                 <span class="ow-txt"><?php echo $text; ?></span>                 <span class="ow-dot"></span>             </a>         </li>         <?php     } }

but when that, variable gets leaked in html, displaying url in random place in dom.

any ideas?

bloginfo() automatically echoes returned value, have seen. return value , store in variable, need use get_bloginfo() instead, e.g.:

$portfolio_link = get_bloginfo('url');

bloginfo ref: https://developer.wordpress.org/reference/functions/bloginfo/
get_bloginfo ref: https://developer.wordpress.org/reference/functions/get_bloginfo/

note: come across many wordpress functions this, 1 version automatically display value , second version (usually preceded get_) return value e.g. the_title / get_the_title

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer
