Wordpress bulk post meta update - php

Question

I am trying to add the ability to update a meta value through Wordpress's bulk post edit menu. I have it working on a single post, but I can't figure out why it's not working for bulk.
// Add our text to the quick & bulk edit box
add_action('quick_edit_custom_box', 'on_quick_edit_custom_box', 10, 2);
add_action('bulk_edit_custom_box', 'on_quick_edit_custom_box', 10, 2);
function on_quick_edit_custom_box($column_name, $post_type) {
global $post;
$postMeta = get_post_meta( $post->ID, 'wpsl_locatorID', true );
if ('wpsl_locatorID' == $column_name && get_post_type() == 'location' ) {
echo "<fieldset class=\"inline-edit-col-right\" style=\"margin-top: 0;\">";
echo "<div class=\"inline-edit-col\">";
echo "<div class=\"inline-edit-group\">";
echo "<label class=\"alignleft\">";
echo "<span class=\"title\" for=\"wpsl_locatorID\">Movie ID</span>";
echo "<input type=\"text\" name=\"wpsl_locatorID\" id=\"wpsl_locatorID\" value=\"{$postMeta}\" />";
echo "</label>";
echo "</div>";
echo "</fieldset>";
};
}
// Update the post meta
add_action( 'save_post', 'locationMetaUpdate', 10, 2 );
function locationMetaUpdate( $post_id ) {
// Bail if we're doing an auto save
if( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE ) return;
// if our nonce isn't there, or we can't verify it, bail
// if un-commented than the value won't update at all. I'm guessing b/c of WP's ajax function vs. reloading the page.
//if( !isset( $_POST['meta_box_nonce'] ) || !wp_verify_nonce( $_POST['meta_box_nonce'], 'my_meta_box_nonce' ) ) return;
// if our current user can't edit this post, bail
if ( ! current_user_can( 'edit_posts' ) ) return;
// Make sure that it is set.
if ( ! isset( $_POST['wpsl_locatorID'] ) ) {
return;
}
// Sanitize user input.
$my_data = sanitize_text_field( $_POST['wpsl_locatorID'] );
// Update the meta field in the database.
update_post_meta( $post_id, 'wpsl_locatorID', $my_data );
};
Like I said above, this works for a single quick edit but not on bulk edit. I've tried to find a solution, but I'm sure it's something simple I'm missing.

Answer 1

So honestly I'm not sure why it's now working; but all I did was condense the action like on WP's save_post codex page.
// Update the post meta
add_action( 'save_post', 'locationMetaUpdate', 10, 3 );
function locationMetaUpdate( $post_id, $post, $update ) {
//print_r($_POST); die();
// if our current user can't edit this post, bail
if ( ! current_user_can( 'edit_posts' ) ) return;
// Make sure that it is set.
if ( isset( $_REQUEST['wpsl_locatorID'] ) ) {
update_post_meta( $post_id, 'wpsl_locatorID', sanitize_text_field( $_REQUEST['wpsl_locatorID'] ) );
}
}
