I'm having problems trying to create a custom type post with taxonomies using a form at the Front End.

I have tried to add several lines of code and use 'tax_input' but I always get errors.

The custom post type is: pet and the taxonomies are pet-category and pet-city. This code is working fine but is only posting the title, and the content.

Please if somebody could tell me what I need to add in order to also post this two taxonomies wold be appreciated. but I have tried and tried without success,

<?php /* Template Name: Insert Posts */

$postTitleError = '';

if(isset($_POST['submitted']) && isset($_POST['post_nonce_field']) && wp_verify_nonce($_POST['post_nonce_field'], 'post_nonce')) {

$postTitle = trim($_POST['postTitle']);

$new_post = array(
'post_title' => wp_strip_all_tags( $_POST['postTitle'] ),
'post_content' => $_POST['postContent'],
'post_type' => 'pet',
'post_status' => 'publish'

);

$post_id = wp_insert_post($new_post,$wperror);

if($post_id)
{

// Update Custom Meta
update_post_meta($post_id, 'vsip_custom_one', esc_attr(strip_tags($_POST['customMetaOne'])));
update_post_meta($post_id, 'vsip_custom_two', esc_attr(strip_tags($_POST['customMetaTwo'])));

// Redirect
wp_redirect( home_url() ); exit;

• custom-post-types
• custom-taxonomy
• front-end

• Thank you so much for your reply, I tried to modify the code and add what you suggest, but I get Parse Error, thanks in advance for your help. – nestorgallego Commented Oct 12, 2013 at 16:11

Your code doesn't assign the terms to the post. You can do this with wp_set_post_terms() which does:

Set terms for a post.

Simplified usage example:

$pet_cat_ term = $_POST['pet_category'];  
wp_set_post_terms( $post_id, $pet_cat_ term, 'pet-category' );

Additional note: use the id as value for your term select(s), to prevent problems, i.e. because for hierarchical terms you have to do it anyways.

Add term for custom taxonomy from front end through ajax

HTML

 <div class="articles_catform">
       <form id="articles_catform" name="articles_catform" class="wordpress-ajax-form2" method="post" action="<?php echo admin_url('admin-ajax.php'); ?>" enctype="multipart/form-data" >
          <input type="text" name="name" placeholder="Category Title">
          <br>
           <textarea name="description" placeholder="Category Description" style="height: 200px !important;"></textarea> 
          <br>

          <input type="hidden" name="action" value="custom_cataction">
          <br>
          <button>Send</button>
       </form>
    </div>

JS

$(".wordpress-ajax-form2").submit(function(evt){  

  if( document.articles_catform.name.value == "") {
  alert( "Please provide Title! " );
  document.articles_catform.name.focus() ;
  return false;
  }
  if(document.articles_catform.description.value == "" ) {
  alert( "Please provide your Description! ");
  document.articles_catform.description.focus() ;
  return false;
  }   

   evt.preventDefault();

      var $form = $(this);
      $.post($form.attr('action'), $form.serialize(), function(data) {
        //return false;

        if(data){

          alert('Category Created Successfully...');
        }
        else {
           alert('Already Exists!!!');
        }

     });

   }); 

Add In function file

add_action('wp_ajax_custom_cataction', 'custom_cataction');
add_action('wp_ajax_nopriv_custom_cataction', 'custom_cataction');
function custom_cataction() {
    $post_name = (trim($_POST['name']));
    $post_description = (trim($_POST['description']));

    $cid = wp_insert_term($post_name, 'articles_category', array(
    'description' => $post_description,
    ));

    if ( is_wp_error($cid) ) {
     //echo $cid->get_error_message();
      echo'';

    }
    else  {
       echo'1'; 
    }

    wp_die();
}
