Get value from a select option and echo content in the header in WordPress -


in theme options allowing users set page 404 template. (which means can create normal page , choose page 404 template). added page dropdown using wp_dropdown_pages().

now want echo noindex,nofollow meta values page user choose obvious seo reasons. tried not work.

function noindex_404(){     global $post;     $option = $_post['404_id'];     // $post_val = '2';      if ($post->id == $option){     //if ($post->id == $post_val)     // if try direct post value, it's working          echo '<meta name="robots" content="noindex,nofollow">';     } }  add_action('wp_head', 'noindex_404', 1);

the following html created wp_dropdown_pages() , page 2 selected under option name of 404_id option value of 2

<select name="404_id" id="404">     <option value="1">page 1</option>     <option value="2" selected="selected">page 2</option>     <option value="3">page 3</option>     <option value="4">page 4</option>     <option value="5">page 5</option>    </select>

you can check 404 page using condition.

if ( is_404() ) { echo '<meta name="robots" content="noindex,nofollow">'; }

in case not bound specific page. ever page used 404 function check if 404 page code echo out otherwise not. cheers!

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
