php - Custom Field Select Box (Adding Select Keyword) -


i have added couple of custom fields wordpress posts, theme creating hobby (cars). having trouble selecting option html select box. if select it, works , save correctly ~ displaying correct value on front end, when return post page, shows first value of options, , not chosen one. example, if select automatic, show on front end, when revisit backend manual again.

i know stick selected post, have add selected keyword choice, having problems.

what i've done

what have done far work tutorial: http://wpshed.com/create-custom-meta-box-easy-way/

i created select box so:

function wpshed_meta_box_output( $post ) {   // create nonce field   wp_nonce_field( 'my_wpshed_meta_box_nonce', 'wpshed_meta_box_nonce' ); ?>      <p>         <label for="transmission_textfield"><?php _e( 'transmition', 'wpshed' ); ?>:</label>         <!-- <input type="text"  value="<?php echo wpshed_get_custom_field( 'transmission_textfield' ); ?>" /> -->          <select name="transmission_textfield" id="transmission_textfield">           <option value="manual" >manual</option>           <option value="automatic">automatic</option>         </select>          </p>     }      function wpshed_meta_box_save( $post_id ) {       if( defined( 'doing_autosave' ) && doing_autosave ) return;        if( isset( $_post['transmission_textfield'] ) )         update_post_meta( $post_id, 'transmission_textfield', esc_attr( $_post['transmission_textfield'] ) );       }     add_action( 'save_post', 'wpshed_meta_box_save' );  ?> 

how can add selected keyword option chosen?

you need set selected property manually on <option> - ie. value , use wordpress function selected() output property in relevant place this:

<?php $selected_option = get_post_meta($post->id, 'transmission_textfield', true); ?> <select name="transmission_textfield" id="transmission_textfield">     <option value="manual" <?php selected($selected_option, 'manual') ?>>manual</option>     <option value="automatic" <?php selected($selected_option, 'automatic') ?>>automatic</option> </select> 

you don't post code wpshed_get_custom_field(), won't use it, i'm guessing it's wrapper get_post_meta()... in case can go ahead , use instead...
