I have a custom post type books and 3 custom taxonomies attached to books. The custom taxonomies are: books-categories , location , services_c. How should i edit my form to get my taxonomies work; I'm trying to solve this for 3 days and but i can't. Can anyone help me please?

<?php
if( 'POST' == $_SERVER['REQUEST_METHOD'] && !empty( $_POST['action'] ) &&  $_POST['action'] == "new_post") {

    // Do some minor form validation to make sure there is content
    if (isset ($_POST['title'])) {
        $title =  $_POST['title'];
    } else {
        echo 'Please enter a  title';
    }
    if (isset ($_POST['description'])) {
        $description = $_POST['description'];
    } else {
        echo 'Please enter the content';
    }
    $tags = $_POST['post_tags'];

    // Add the content of the form to $post as an array
    $new_post = array(
        'post_title'    => $title,
        'post_content'  => $description,
        'tags_input'    => array($tags),
        'post_status'   => 'draft',           // Choose: publish, preview, future, draft, etc.
        'post_type' => 'books'  //'post',page' or use a custom post type if you want to
    );
    //save the new post
    $pid = wp_insert_post($new_post); 

}

• This is a duplicate, of your own question - wordpress.stackexchange/questions/247409/… – Dan. Commented Nov 27, 2016 at 14:01
• You need to read my answer again, and try what I posted, as I can see from the code in your new question that you missed a couple bits. when calling wp_dropdown_categories you need to add a parameter which will give the form element a different name (at the moment all those dropdowns have the same name). – Dan.

Your logic is a little flawed - you run isset checks on fields like title and description, but don't actually halt the post insertion if they're not set.

You also don't check the post_tags index, which will never exist because wp_dropdown_categories will use the field name cat unless you set it to something else.

Not to mention that tags_input is specifically for the taxonomy post_tag, so even if everything else was working, the terms would never be properly assigned.

Let's refactor and use the PHP filter API while we're at it:

<?php

if ( 'POST' === $_SERVER['REQUEST_METHOD'] && filter_input( INPUT_POST, 'action' ) === 'new_post' ) {
    $errors      = [];
    $title       = filter_input( INPUT_POST, 'title',       FILTER_SANITIZE_STRING );
    $description = filter_input( INPUT_POST, 'description', FILTER_SANITIZE_STRING );

    if ( ! $title ) {
        $errors[] = 'Please enter a title';
    }

    if ( ! $description ) {
        $errors[] = 'Please enter a description';
    }

    if ( ! $errors ) {
        $new_post_id = wp_insert_post([
            'post_title'   => $title,
            'post_content' => $description,
            'post_status'  => 'draft',
            'post_type'    => 'books',
        ]);

        if ( ! $new_post_id ) {
            $errors[] = 'Oops, something went wrong';
        } else {
            /**
             * Loop over taxonomies and attempt to set post terms.
             */
            foreach ([
                'books-categories',
                'location',
                'services_c',
            ] as $post_taxonomy ) {

                // Field name is the format "{taxonomy}_term_id"
                if ( $term_id = ( int ) filter_input( INPUT_POST, "{$post_taxonomy}_term_id" ) ) {
                    wp_set_object_terms( $new_post_id, $term_id, $post_taxonomy );
                }
            }
        }
    }

    foreach ( $errors as $error ) {
        echo "$error<br />";
    }
}

Now we just need to set the right input name for each taxonomy dropdown - I've used the format {taxonomy}_term_id so as not to confuse WordPress (if you used just the taxonomy name as the input, it will likely clash with the query_var for said taxonomy).

wp_dropdown_categories( 'name=books-categories_term_id&show_option_none=Category&tab_index=4&taxonomy=books-categories' );

Do the same for the others and you should be good to go.

  add_filter('single_template', 'my_single_template');
    function my_single_template() {
        global $post;
        $this_plugin_dir = WP_PLUGIN_DIR . '/' . str_replace(basename(__FILE__), "", plugin_basename(__FILE__));
        //echo $post->post_type; exit;
        /* Checks for single template by post type */
        if ($post->post_type == 'articles') {
            if (file_exists($this_plugin_dir . '/templates/single-articles.php')) {
                return $this_plugin_dir . '/templates/single-articles.php';
            }
        }
        return $single;
    }
