javascript - Change chevron on click event -

-
i want change chevron down up based on user's onclick event. i've tried using other samples other people not work out. this jsfiddle . well, have couple of problems setup of jsfiddle, i'm assuming secondary actual problem. the easiest way use .toggleclass() (i'm assuming you're okay using jquery since use $(document).ready() , include in fiddle). you can use (classname, switch) signature add or remove classes: $(element).toggleclass("myclass", false) // removes myclass $(element).toggleclass("myotherclass", true) // adds myotherclass so, if add var change = true in .ready() , can switch between 2 glyphicons on each click: function toggle_caret() { $("#caret1").toggleclass("glyphicon-chevron-up", change); $("#caret1").toggleclass("glyphicon-chevron-down", !change); change = !change } demo var change = true; $(document).ready(function () { $('[da...

Wordpress plugin to do something on post publish -

-
i new wordpress. writing custom plugin take post title post url , post content of newly published post , store in other store in background. using "publish_post" action same. however, don't think gets invoked. i have few queries around : which api action / filter me achieve above problem statement ? is best use actions or filters ? how identify whether action registered ? how identify if action invoked ? tried putting echo statement not seem display. on "publish" click, icon next button keeps going round denote publish in progress. confused. kindly help. ! you can add save_post hook : add_action( 'save_post', 'save'); function save( $id ){ if( get_post_status( $id ) == 'publish' ) { } } for action vs filter question: these not can interchange; different beasts. think way: filter can alter value (so need return value), action can't.
