Update wp_term_relationships table by using the value of wp_postmeta - php

Question

Hello There I have created a meta box for date in my functions.php of admin. The code is here:-
function ep_eventposts_metaboxes() {
//add_meta_box( 'ept_event_date_start', 'Start Date and Time', 'ept_event_date', 'event', 'side', 'default', array( 'id' => '_start') );
add_meta_box( 'ept_event_date_end', 'Expiratory Date and Time', 'ept_event_date', 'post', 'side', 'default', array('id'=>'_end') );
//add_meta_box( 'ept_event_location', 'Event Location', 'ept_event_location', 'event', 'normal', 'default', array('id'=>'_end') );
}
add_action( 'admin_init', 'ep_eventposts_metaboxes' );
// Metabox HTML
function ept_event_date($post, $args) {
$metabox_id = $args['args']['id'];
global $post, $wp_locale;
// Use nonce for verification
wp_nonce_field( plugin_basename( __FILE__ ), 'ep_eventposts_nonce' );
$time_adj = current_time( 'timestamp' );
$month = get_post_meta( $post->ID, $metabox_id . '_month', true );
if ( empty( $month ) ) {
$month = gmdate( 'm', $time_adj );
}
$day = get_post_meta( $post->ID, $metabox_id . '_day', true );
if ( empty( $day ) ) {
$day = gmdate( 'd', $time_adj );
}
$year = get_post_meta( $post->ID, $metabox_id . '_year', true );
if ( empty( $year ) ) {
$year = gmdate( 'Y', $time_adj );
}
$hour = get_post_meta($post->ID, $metabox_id . '_hour', true);
if ( empty($hour) ) {
$hour = gmdate( 'H', $time_adj );
}
$min = get_post_meta($post->ID, $metabox_id . '_minute', true);
if ( empty($min) ) {
//$min = '00';
$min = gmdate( 'i', $time_adj );
}
$month_s = '<select name="' . $metabox_id . '_month">';
for ( $i = 1; $i < 13; $i = $i +1 ) {
$month_s .= "\t\t\t" . '<option value="' . zeroise( $i, 2 ) . '"';
if ( $i == $month )
$month_s .= ' selected="selected"';
$month_s .= '>' . $wp_locale->get_month_abbrev( $wp_locale->get_month( $i ) ) . "</option>\n";
}
$month_s .= '</select>';
echo $month_s;
echo '<input type="text" name="' . $metabox_id . '_day" value="' . $day . '" size="2" maxlength="2" />';
echo '<input type="text" name="' . $metabox_id . '_year" value="' . $year . '" size="4" maxlength="4" /> # ';

echo '<input type="text" name="' . $metabox_id . '_minute" value="' . $min . '" size="2" maxlength="2" />';
}

add_action( 'save_post', 'ep_eventposts_save_meta', 1, 2 );
/**

// Get the Month Abbreviation
function eventposttype_get_the_month_abbr($month) {
global $wp_locale;

$eventdate .= ' ' . get_post_meta($post->ID, '_day', true) . ',';

}
It works fine and adding the metabox on post. And Putting the value in wp_postmeta.
Now i have created a function to change the value add a TaxonomyID for the post after the condition satisfies. The code is here:-
function wp_insert_category_to_post()
{
$postid=get_the_ID();
echo $meta_values = get_post_meta( $postid, '_end_minute', true )."</br>";
echo $meta_values = get_post_meta( $postid, '_end_hour', true )."</br>";
echo $meta_values1 = get_post_meta( $postid, '_end_month', true )."</br>";
echo $meta_values2 = get_post_meta( $postid, '_end_day', true )."</br>";
echo $meta_values3 = get_post_meta( $postid, '_end_year', true )."</br>";
echo $meta_values3 = get_post_meta( $postid, '_end_eventtimestamp', true )."</br>";
global $wpdb;
foreach( $wpdb->get_results("SELECT * FROM wp_postmeta where meta_key='_end_eventtimestamp' And meta_value between '2015-07-01' and now() ;") as $key => $row) {
// each column in your row will be accessible like this
$my_column = $row->post_id;
//$wpdb->insert($wpdb->wp_term_relationships, array("object_id" => $row->post_id, "term_taxonomy_id" => 3, "term_order" => 0), array("%d", %d", "%d"));
$sql = $wpdb->prepare( "INSERT INTO $wpdb->wp_term_relationships (object_id, term_taxonomy_id,term_order ) VALUES ( %d, %d, %d )", $row->post_id, 3, 0 );
print_r($sql);
$res= $wpdb->query($sql);
//$wpdb->query($sql);
//echo "<br> My value = ".$my_column."<br>";
}
return $res;
}
add_action)('init','wp_insert_category_to_post');
It is written in post.php of wp-admin. But Its not working. can any one tell me the reason. And give the solution.
