Backend post editor sidebar module - custom field radio selector WordPress

Christianto answers:

Hi Josh,

Is this metabox under post editor?
I use [[LINK href="http://wordpress.org/extend/plugins/meta-box/"]]rilwis metabox plugin here[[/LINK]], and its awesome!!

you simply activated the plugin and [[LINK href="http://pastebin.com/ipKtSsV0"]]paste this code[[/LINK]] to functions.php
and to access the value you can use ordinary get_meta_post() on the loop:
<?php get_post_meta(get_the_ID(),'_app_visibility', true); ?>
besure to match the the prefix "_app_" I add to the code and the id of each metabox field created for the field name "_app_visibility":
'id' => "{$prefix}visibility"

with this you can assign the metabox to more/less custom post type, by changing this code :
'pages' => array( 'on_road', 'off_road' ),
(as you can see I add the custom field to "on_road" and "off_road" custom post type)

please note that custom post type name cannot contain capital letter or space, you can use capital or space as label.. :D

and you can add different metabox to different custom post type or add other type of custom metabox field like image upload easily..
you can check the demo.php on the plugin demo folder included on the plugin.. :D


Hope this help..

// if our current user can't edit this post, bail

// now we can actually save the data
$allowed = array(
'a' => array( // on allow a tags
'href' => array() // and those anchords can only have href attribute
)
);

// Probably a good idea to make sure your data is set
if( isset( $_POST['app_visibilty'] ) )
update_post_meta( $post_id, 'app_visibilty', $_POST['app_visibilty']);

}

-----------
For modify or add to a new meta box:
- edit/add html code into function custom_meta_post_sb_meta (notice: input/select/texarea ... with <strong>name="_custom_meta[another_custom_meta]"</strong> )
- [defaults] insert new_custom_meta_name into array <strong>$custom_meta_defaults</strong> in function custom_meta_post_sb_save

codex: checked/selected
http://codex.wordpress.org/Function_Reference/checked
http://codex.wordpress.org/Function_Reference/selected

example with selected

function custom_meta_post_sb() {
global $post
$my_option = array(
'Options 1' => 'value1',
'Options 2' => 'value2'
);
?>
<p>
<label for="my_option_meta_input">Example</label>
<select name="_custom_meta[my_option_meta_input]" id="my_option_meta_input">
<?php

}
?>
</select>

Hi Josh,

I would strongly recommend using the Advanced Custom Fields plugin to do what you want. It is free, incredibly easy to use and very powerful. I have used it on many sites. You can add any metaboxes you want to any custom post types.
