Modules with meta box implementations

2 comments

1. I recently published a meta box class named My Meta Box which takes care of most of the metabox creation and data saving and that was forked out of from Meta Box script by Rilwis.

   Using the class is simple eg:

   <?php
   
   require_once("meta-box-class/my-meta-box-class.php");
   if (is_admin()){
   /*
   * prefix of meta keys, optional
   * use underscore (_) at the beginning to make keys hidden, for example $prefix = '_ba_';
   * you also can make prefix empty to disable it
   *
   */
   $prefix = 'ba_';
   /*
   * configure your meta box
   */
   $config = array(
   'id' => 'demo_meta_box', // meta box id, unique per meta box
   'title' => 'Demo Meta Box', // meta box title
   'pages' => array('post', 'page'), // post types, accept custom post types as well, default is array('post'); optional
   'context' => 'normal', // where the meta box appear: normal (default), advanced, side; optional
   'priority' => 'high', // order of meta box: high (default), low; optional
   'fields' => array(), // list of meta fields (can be added by field arrays)
   'local_images' => false // Use local or hosted images (meta box images for add/remove)
   );
   /*
   * Initiate your meta box
   */
   $my_meta = new AT_Meta_Box($config);
   
   /*
   * Add fields to your meta box
   */
   
   //text field
   $my_meta->addTextField($prefix.'text_field_id',array('name'=> 'My Text Field'));
   //textarea field
   $my_meta->addTextareaField($prefix.'textarea_field_id',array('name'=> 'My Textarea Field'));
   //checkbox field
   $my_meta->addCheckboxField($prefix.'checkbox_field_id',array('name'=> 'My Checkbox Field'));
   //select field
   $my_meta->addSelectField($prefix.'select_field_id',array('selectkey1'=>'Select Value1','selectkey2'=>'Select Value2'),array('name'=> 'My select Field', 'std'=> array('selectkey2')));
   //checkboxList
   $my_meta->addCheckboxListField($prefix.'ch_list_field_id',array('selectkey1'=>'Select Value1','selectkey2'=>'Select Value2'),array('name'=> 'My CheckBox List Field', 'std'=> array('selectkey2')));
   //radio field
   $my_meta->addRadioField($prefix.'radio_field_id',array('radiokey1'=>'Radio Value1','radiokey2'=>'Radio Value2'),array('name'=> 'My Radio Filed', 'std'=> array('radionkey2')));
   //date field
   $my_meta->addDateField($prefix.'date_field_id',array('name'=> 'My Date Field'));
   //Time field
   $my_meta->addTimeField($prefix.'time_field_id',array('name'=> 'My Time Field'));
   //Color field
   $my_meta->addColorField($prefix.'color_field_id',array('name'=> 'My Color Field'));
   //Image field
   $my_meta->addImageField($prefix.'image_field_id',array('name'=> 'My Image Field'));
   //file upload field
   $my_meta->addFileField($prefix.'file_field_id',array('name'=> 'My File Field'));
   //wysiwyg field
   $my_meta->addWysiwygField($prefix.'wysiwyg_field_id',array('name'=> 'My wysiwyg Editor Field'));
   //taxonomy field
   $my_meta->addTaxonomyField($prefix.'taxonomy_field_id',array('taxonomy' => 'category'),array('name'=> 'My Taxonomy Field'));
   //posts field
   $my_meta->addPostsField($prefix.'posts_field_id',array('post_type' => 'post'),array('name'=> 'My Posts Field'));
   
   /*
   * To Create a reapeater Block first create an array of fields
   * use the same functions as above but add true as a last param
   */
   
   $repeater_fields[] = $my_meta->addTextField($prefix.'text_field_id',array('name'=> 'My Text Field'),true);
   $repeater_fields[] = $my_meta->addTextareaField($prefix.'textarea_field_id',array('name'=> 'My Textarea Field'),true);
   $repeater_fields[] = $my_meta->addCheckboxField($prefix.'checkbox_field_id',array('name'=> 'My Checkbox Field'),true);
   
   /*
   * Then just add the fields to the repeater block
   */
   //repeater block
   $my_meta->addRepeaterBlock($prefix.'text_field_id',array('inline' => true, 'name' => 'This is a Repeater Block','fields' => $repeater_fields));
   /*
   * Don't Forget to Close up the meta box decleration
   */
   //Finish Meta Box Decleration
   $my_meta->Finish();
   }
   

   Take a look at the class-usage-demo.php file which can also be tested as a WordPress Plugin. Other options are available for each field which can be see in the ‘my-meta-box-class.php’ file.

   And also you can see it in use in my latest plugin ShortCodes UI

2. I’m not exactly sure what you’re asking here, but the most basic example you can get here, along with everything else there is to know about add_meta_box, complete with save code and security checks:

   http://codex.wordpress.org/Function_Reference/add_meta_box

   <?php
   /* Define the custom box */
   add_action( 'add_meta_boxes', 'myplugin_add_custom_box' );
   
   
   /* Do something with the data entered */
   add_action( 'save_post', 'myplugin_save_postdata' );
   
   /* Adds a box to the main column on the Post and Page edit screens */
   function myplugin_add_custom_box() {
       add_meta_box( 
           'myplugin_sectionid',
           __( 'My Post Section Title', 'myplugin_textdomain' ),
           'myplugin_inner_custom_box',
           'post' 
       );
   }
   
   /* Prints the box content */
   function myplugin_inner_custom_box( $post ) {
   
     // Use nonce for verification
     wp_nonce_field( plugin_basename( __FILE__ ), 'myplugin_noncename' );
   
     // The actual fields for data entry
     echo '<label for="myplugin_new_field">';
          _e("Description for this field", 'myplugin_textdomain' );
     echo '</label> ';
     echo '<input type="text" id="myplugin_new_field" name="myplugin_new_field" value="whatever" size="25" />';
   }
   
   /* When the post is saved, saves our custom data */
   function myplugin_save_postdata( $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;
   
     // 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;
   
   
     // Check permissions
     if ( 'page' == $_POST['post_type'] ) 
     {
       if ( !current_user_can( 'edit_page', $post_id ) )
           return;
     }
     else
     {
       if ( !current_user_can( 'edit_post', $post_id ) )
           return;
     }
   
     // OK, we're authenticated: we need to find and save the data
   
     $mydata = $_POST['myplugin_new_field'];
   
     // Do something with $mydata 
     // probably using add_post_meta(), update_post_meta(), or 
     // a custom table (see Further Reading section below)
   }
   ?>
