How can a category be assigned to a new front-end post submission?

Posting works, Category is not assigned. Would like to be able to add more than one, if possible.
Both are CPT and custom taxonomies.

if ( isset( $_POST['submitted'] ) && isset( $_POST['new_post_nonce_field'] ) && wp_verify_nonce( $_POST['new_post_nonce_field'], 'new_post_nonce_action' ) ) {

    $new_post = array(
        'post_content'  =>  $_POST['post-content'],
        'post_title'    =>  wp_strip_all_tags( $_POST['post-title'] ),
        'post_type'     => 'custom_pt',
        'post_category' =>  array( 
            'custom_tax' => $_POST['custom_tax']
        ),
    );  

    if ( !$hasError == true ) {            
        $post_id = wp_insert_post( $new_post );        
        if ( post_id ) {
            wp_redirect( home_url() );
        }
    }
}

.

    <form id="new_post" method="POST" action="" enctype="multipart/form-data">

        <label for="post-title">The Title</label>
        <input id="post-title" name="post-title" type="text" />

        <label for="post-content">The Content</label>
        <textarea id="post-content" name="post-content"></textarea>

        <label for="custom_tax">The Categories</label>
        <?php wp_dropdown_categories( 'tab_index=10&taxonomy=custom_tax&name=custom_tax&class=custom_tax&show_option_all=Select a category' ); ?>

    <?php wp_nonce_field( 'new_post_nonce_action', 'new_post_nonce_field' ); ?>

        <button type="submit">Publish</button>
        <input type="hidden" name="submitted" id="submitted" value="true" />

    </form>

Thank You.

I checked and it works with this:

$new_post = array(
    'post_content'  =>  $_POST['post-content'],
    'post_title'    =>  wp_strip_all_tags( $_POST['post-title'] ),
    'post_type'     => 'custom_pt'
);

note: I used a text input for the single category

<input id="input-name-value" name="input-name-value" type="text" />

I havent tried it with a select - option dropdown. or more than 1 category.

$post_id = wp_insert_post( $new_post );

wp_set_object_terms( $post_id, $_POST['input-name-value'], 'yourCategory' );

It would be nice if someone could pimp this out in order to get full functionallity.

Thanks.

Found this:

$postCats = trim( $_POST['post-cats']; )
$postCats = explode( ',', $postCats );

wp_set_object_terms( $post_id, array( $postCats[0], $postCats[1], $postCats[2], $postCats[3], $postCats[4] ), 'category' );

Works the same for tags

I'm still wondering if there is a way to add unlimited categories without declaring a limited number in an array (like above).

'd be great if someone helped me out with that.

By using wp_set_object_terms you can set post category , for more details please follow this link https://codex.wordpress.org/Function_Reference/wp_set_object_terms
