javascript - Isotope Plugin: Only generating filters for specific categories? -


i used tutorial provided alicia ramirez set isotope plugin wordpress page. goal simple masonry layout posts + option filter them.

through tutorial learned how generate filters categories set in backend , subsequently load posts. done piece of code:

<ul id="filters" class="cat-filter">     <li><a href="#" data-filter="*" class="selected">alles</a></li>     <?php          $terms = get_terms("category");         // categories, can use taxonomy         $count = count($terms);                 // how many they?         if ( $count > 0 ){                      // if there more 0 terms             foreach ( $terms $term ) {       // each term:                 echo "<li><a href='#' data-filter='.".$term->slug."'>" . $term->name . "</a></li>\n";                 //create list item current term slug sorting, , name label             }         }      ?> </ul>

i know how might able generate filters , load posts of specific set of categories, rather of them. can changing initial piece of code gets categories via $terms = get_terms("category");?

get_terms accepts array of arguments contains parameters specify terms want returned.

you don't how identify specific categories, i'll use term names in example, can change search slug, term id, meta_query or else allowed.

example terms terms named "news" , "events" only

$args = array( 'names' => array( "news", "events"));  $terms = get_terms("category", $args);

if wanted terms specific ids, use like: $args = array( 'include' => array( 1,4,7 )); // term ids 1,4 , 7 only

ref: all parameters allowed in $args

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
