 * hi @ all,
 * i’ve got a problem by adding customfields into ma wiordpress theme. the name/
   id of the customfield shell be predefined, the Text/value shell be customizable.
 * [php]
 * add_action( ‘save_post’, ‘kb_custom_field_default’, 10, 2 );
 * function kb_custom_field_default( $post_id, WP_Post $post ) {
    if (!get_post_meta(
   $post_id, ‘CUSTOM-FIELD-KEY’, true ) ) { update_post_meta( $post_id, ‘a, ‘value1’);
   update_post_meta( $post_id, ‘b’, ‘value2’ ); update_post_meta( $post_id, ‘c’,‘
   value3’ ); } }
 * [/php]
 * So how can i release this. ID/name is working but the value is always the one
   i typed into the functions.php (value1, value2, value3) how can i change that
   to custom text?
 * best regards

 * The best place to start is with adding a metabox. You can see the developer documentation
   here: [https://developer.wordpress.org/reference/functions/add_meta_box/](https://developer.wordpress.org/reference/functions/add_meta_box/)
 * Once you’re comfortable with that, or if you need something more simplistic, 
   check this out: [https://wordpress.org/plugins/cmb2/](https://wordpress.org/plugins/cmb2/)
 * Basically you need a metabox to actually accept the data, or your ‘customized
   values’. Once you have that, then, and only then should you be using save-post
   hook to update the meta data.

 * Assuming you do have a metabox sending data, and the field names are field1, 
   field2, field3, then something like this will save the entered values:
 *     ```
       update_post_meta( $post_id, 'a', sanitize_text_field( $_POST['field1']));
       update_post_meta( $post_id, 'b', sanitize_text_field( $_POST['field2']));
       update_post_meta( $post_id, 'c', sanitize_text_field( $_POST['field3']));
       ```
   
 * BTW, a lot of BBcode like `[php]` do not work here, next time you post code please
   use ``backticks`` or use the ‘code’ button above the edit box.

 * Okay Got it! 🙂
 * …now i changed the code and startet constructing a plugin.
 * Everything is working as it should. Posts are shown on search.php and so on… 
   only when i klick on an article (wich is generated by my plugin) i get redirected
   to the startsite of my page :/
 * So i searched for a solution, i read about i have to add a new single.php to 
   my cstum-template which has to be named single-myposttypenam.php.
 * So the posttype is registered as ements
 *     ```
       register_post_type(
               'ements',
       ```
   
 * also i added a data which is named single-ements.php and added the code of the
   single.php into ist.
 * But still, when i click on an article iIm getting redirected to my startpage :/
 * What am i doing wrong??? :S
 * thanks a lot for helping and Best regards 🙂

 * There’s something wrong with how links are generated on search.php. Please post
   the code within the loop section of that file, specifically the code that generates
   the output you are clicking on, and anything prior to that that is used to influence
   the output.
 * Posting a link to the search results page with the bad links would also be helpful.

   than everything is working finally! 🙂
 * THanks to everybody! 🙂
