richardukI've checked out the data validation page on the codex http://codex.wordpress.org/Data_Validation and the wp_kses page too http://codex.wordpress.org/Function_Reference/wp_kses
I'm not quite sure how to validate text boxes and text areas for custom fields.
I can't find anything authoritative that I can comprehend on the internet.
Can anyone tell me how to validate using wp_kses? Apparently 'You have to remove any slashes from PHP's magic quotes before you call this function' (wp_kses codex page).
The outline of the code that I'm using for my customised custom fields is:
$meta_box = array
(
'title' => 'blah',
'something => 'whatever',
);
function show_box( )
{
foreach ( $meta_box['fields'] as $field ) {
case 'text':
echo '<label class="custom-fields ....
echo '<input class="custom-fields ......
}
add_action( 'save_post', 'save_data' );
function save_data( $post_id ) {
if ( !wp_verify_nonce( $_POST['developer_theme_meta_box_nonce'] ...
if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE ) ...
if ( 'page' == $_POST['post_type'] ) ....
function custom_fields( ) {
foreach ( $meta_box['page'] as $page ) {
add_meta_box( $meta_box['id'], $meta_box['title'], 'show_box',.....
if ( current_user_can( 'administrator' ) ) :
add_action( 'admin_menu', 'custom_fields' ); ....
