WP Front End Form Not Saving My Custom Taxonomies - wordpress

Question

I am trying to create a front end posting form through wordpress that will allow users to create a post when schools are closed. I have 4 custom taxonomies closed_schools, study_open, safe_arrival, hour_delay. each has the same list of 3o or so schools. The problem is that I can't display which schools have been selected under there categories after the post is created. If I build the post in the back end it works, just not from the front end, SO I know there is something wrong with how I am storing the taxonomies. Any suggestion are very welcomed, thanks
My Front End Form Template
if(isset($_POST['submit'])){
$title = $_POST['title'];
$description = $_POST['description'];
$category = $_POST['cat'];
$tags = $_POST['post_tags'];
$terms = $_POST['terms'];
$error_msg = array();
if($title == ''){
$error_msg[] = 'Please select an area and/or region.';
}
if($description == ''){
$error_msg[] = 'Please write a description for the closure and/or delay.';
}
if($category == '-1'){
$error_msg[] = 'Please identify the reason for the closure and/or delay.';
}
else if( !$error_msg && 'POST' == $_SERVER['REQUEST_METHOD'] && !empty( $_POST['action'] ) && $_POST['action'] == "new_post"){
$new_post = array(
'post_title' => $title,
'post_content' => $description,
'post_category' => array($_POST['cat']), // Usable for custom taxonomies too
'tags_input' => array($tags),
'tax_input' => array(
'closed_schools' => $_POST['terms'],
'study_open' => $_POST['terms'],
'safe_arrival' => $_POST['terms'],
'hour_delay' => $_POST['terms'],
),
'post_status' => 'publish', // Choose: publish, preview, future, draft, etc.
'post_type' => 'post', //'post',page' or use a custom post type if you want to
);
//SAVE THE POST
$pid = wp_insert_post($new_post);
//SET OUR TAGS UP PROPERLY
wp_set_post_tags($pid, $_POST['post_tags']);
//SET OUR POST TERMS, CUSTOM TAXONOMIES
wp_set_post_terms($pid, $_POST['terms'], 'closed_schools', 'safe_open', 'safe_arrival', 'hour_delay', true);
//REDIRECT TO THE NEW POST ON SAVEs
$link = get_permalink( $pid );
wp_redirect( $link );
//POST THE POST
do_action('wp_insert_post', 'wp_insert_post');
}
}
Inside the Form I display the schools in check boxes from the 4 taxonomies like so. I just change the names out for each taxonomy I am showing.
<fieldset>
<label for="closed_schools" class="selection-title">Closed Schools:</label>
<?php
$closed_schools = get_terms('closed_schools', 'orderby=id&hide_empty=0');
$counter = 0;
foreach ($closed_schools as $close) {
$counter++;
$option = '<label for="'.$close->slug.'">'.$close->name.'</label>';
$option .= '<input type="checkbox" name="terms[]" id="'.$close->slug.'" value="'.$close->slug.'">';
echo $option;
}
?>
</fieldset>
Finally I show output the terms on loop.php and single.php
<?php echo get_the_term_list( $post->ID, 'closed_schools', '<strong>Closed Schools:</strong> ', ', ', '' ); ?>
<?php echo get_the_term_list( $post->ID, 'study_open', '<strong>Open For Study Purposes Only:</strong> ', ', ', '' ); ?>
<?php echo get_the_term_list( $post->ID, 'safe_arrival', '<strong>Open for Students Who Can Ariive Safely:</strong> ', ', ', '' ); ?>
<?php echo get_the_term_list( $post->ID, 'hour_delay', '<strong>2 Hour Delay:</strong> ', ', ', '' ); ?>

Answer 1

I figured it out! Here is my answer.
I needed to use wp_set_object_terms instead of wp_set_post_terms for each and it worked
//SET OUR POST TERMS, CUSTOM TAXONOMIES
wp_set_object_terms($pid, $_POST['terms'], 'closed_schools');
wp_set_object_terms($pid, $_POST['terms'], 'study_open');
wp_set_object_terms($pid, $_POST['terms'], 'safe_arrival');
wp_set_object_terms($pid, $_POST['terms'], 'hour_delay');
