javascript - Function has inconsistent return points -


when running intellij's inspections on javascript wrote, reports

function 'createpages' has inconsistent return points @ line 35

but i'm not sure means, or how solve issue.

the function looks this:

function createpages(noofcounts) {     var default_page = 1, default_count = 15;     if (noofcounts != "" && noofcounts != null) {         if (noofcounts > default_count) {             try {                 var tempval = parseint(noofcounts / default_count);                 jquery("#page").val(tempval);                 return true;             }             catch (e) {                 alert('error . ' + e);             }         } else {             alert("it should not less 15 , should number");             return false;         }     }     else {         jquery("#page").val(default_page);         return true;     } }

and being called so: 

var valid = createpages(noofcounts);

your function (in effect) return undefined implicitly after reaches alert('error . ' + e);, because execution reach end of function without explicit return.

so making sure code paths through function return value explicitly rid of intellij error.

php - Calling a template part from a post -

i include iframe within post in wordpress. located inside content of post, meaning cannot in post template file, otherwise either before or after. i'd add facebook plugin within posts: <div id="socialwrap"><div class="fb-like" data-href="http://onlinearizonahomes.info" data-send="true" data-width="450" data-show-faces="true" data-font="arial"></div></div> i thinking of calling template part within post <?php get_template_part( 'social' ); ?> cannot use php within post without plugin (i'd avoid using plugin this). an alternative using javascript create html in post, seems unnecessary use of javascript. what best way add html within wordpress post? you can use shortcode. add functions.php function cudjex_fbshare( $atts, $content = null ) { global $post; $link = get_permalink($post->id); return '<div id="socialwrap...
