Help with add_post_meta... (3 posts)

    I'm working on a plugin that takes info typed into a field (inside a meta box on the Edit Post page), and saves it with the post. More or less like a custom field.

    Code is all taken from examples on wordpress.org.

    Anyway, I can't seem to save the content of the field into the post's meta data! Help!

    Plugin Name: Routines List Panel
    Plugin URI: http://www.roestudios.com/
    Description: Adds a panel with dropdown for routines.
    Author: Benjamin Allison
    Version: 1.0
    Author URI: http://www.roestudios.com/
    /* Use the admin_menu action to define the custom boxes */
    add_action('admin_menu', 'myplugin_add_custom_box');
    /* Use the save_post action to do something with the data entered */
    add_action('save_post', 'myplugin_save_postdata');
    /* Adds a custom section to the "advanced" Post and Page edit screens */
    function myplugin_add_custom_box() {
      if( function_exists( 'add_meta_box' )) {
        add_meta_box( 'myplugin_sectionid', __( 'Routines List', 'myplugin_textdomain' ),
                    'myplugin_inner_custom_box', 'post', 'advanced' );
       } else {
        add_action('dbx_post_advanced', 'myplugin_old_custom_box' );
    /* Prints the inner fields for the custom post/page section */
    function myplugin_inner_custom_box() {
      // Use nonce for verification
      echo '<input type="hidden" name="myplugin_noncename" id="myplugin_noncename" value="' .
        wp_create_nonce( plugin_basename(__FILE__) ) . '" />';
      // The actual fields for data entry
      echo '<label for="myplugin_new_field">' . __("Select a routine for this client <br /><br />", 'myplugin_textdomain' ) . '</label> ';
    	$yeye = get_post_meta( $post_id, 'routine_selection' );
      echo '<input type="text" name="myplugin_new_field" value="'.$yeye.'" size="25" />';
    /* When the post is saved, saves our custom data */
    function myplugin_save_postdata( $post_id ) {
      // verify this came from the our screen and with proper authorization,
      // because save_post can be triggered at other times
      if ( !wp_verify_nonce( $_POST['myplugin_noncename'], plugin_basename(__FILE__) )) {
        return $post_id;
      // verify if this is an auto save routine. If it is our form has not been submitted, so we dont want
      // to do anything
      if ( defined('DOING_AUTOSAVE') && DOING_AUTOSAVE )
        return $post_id;
      // Check permissions
      if ( 'page' == $_POST['post_type'] ) {
        if ( !current_user_can( 'edit_page', $post_id ) )
          return $post_id;
      } else {
        if ( !current_user_can( 'edit_post', $post_id ) )
          return $post_id;
      // OK, we're authenticated: we need to find and save the data
      $mydata = $_POST['myplugin_new_field'];
    	add_post_meta($post_id, 'routine_selection', $mydata, true) or update_post_meta($post_id, 'routine_selection', $mydata);
    	return true;
      // Do something with $mydata
      // probably using add_post_meta(), update_post_meta(), or
      // a custom table (see Further Reading section below)

    Ok, I realized the plugin is 100% storing the info... it'm just not able to retrieve it...

    The following code works when viewing the published page, but not within the admin panel; why?

    $yeye = get_post_meta( $post_id, 'routine_selection' );
    echo $yeye;

    Ok, so I had to do the following:

    global $post;
    $yeye = get_post_meta( $post->ID, 'routine_selection', true);
    echo $yeye;

    Thanks team.
