Question

I have displayed the custom taxonomies in the drop down as you see in the red box i want to ask that how can i submit them with the post .I can't figure it out.`

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

// ADD THE FORM INPUT TO $new_post ARRAY
$new_post = array(
'post_title'    =>  $title,
'tax_input' => array(
    'industries' =>  $_REQUEST['taxonomy_id'] ),
'post_status'   =>  'publish',           // Choose: publish, preview, future, draft, etc.
'post_type' =>  'websites'  //'post',page' or use a custom post type if you want to
);

//SAVE THE POST
$pid = wp_insert_post($new_post);

Update your form to include the term-id, instead of just <input type="checkbox" /> use <input type="checkbox" name="taxonomy_id[]" value="'. $industryterm->term_id .'" />. That way you are actually sending along some values, in this case the term id.

And in the args for wp_insert_post() make sure to include something like this:

'tax_input' => array(
    'industries' => $_REQUEST['taxonomy_id']
)
