posting twice from an array?

Question

I dynamically create iterations of a form field with jquery, but they all carry the name extrakosten[] for the first variable and the other variable vergoeding[].

The php:

$postTitle = ''; // save post title

if(isset(   $_POST['submit']    )){             // if submit button is present

    for ($i=0; $i < count($_POST['vergoeding']); $i++) {

        $new_post = array(
            'post_title'    =>  $postTitle,
            'post_content'  =>  ' ',                        // can not be empty
            'post_status'   =>  'publish',          
            'post_type'     =>  'landschapselement'         // custom post type
        );
        $pid = wp_insert_post($new_post);                   // insert the post

        wp_set_post_terms( $pid, $_POST['extrakosten'],'kostenpost',false);
        wp_set_post_terms( $pid, $_POST['vergoeding'],'vergoedingaanleg',false);

} // close for loop

}

What happens now, is that when I click the submit button, a new post under custom post type 'landschapspakket' is made. The values under vergoeding and kostenpost are being posted in the custom taxonomy 'vergoedingaanleg' and 'kostenpost'.

What it does now, is create ONE post with TWO values for 'kostenpost' and 'vergoeding'. What I try to achieve is to create TWO posts, each with ONE value for both 'kostenpost' and 'vergoeding'.

I think something might be wrong with the array. I'm new to arrays. Any suggestions? Thanks for the help

You could try something like this:

$postTitle = ''; // save post title

if(isset( $_POST['submit'])){             // if submit button is present

    $vergoeding=$_POST['vergoeding'];
    $extrakosten=$_POST['extrakosten'];

    for ($i=0; $i < count($vergoeding); $i++) {

        $new_post = array(
            'post_title'    =>  $postTitle,
            'post_content'  =>  ' ',                        // can not be empty
            'post_status'   =>  'publish',          
            'post_type'     =>  'landschapselement'         // custom post type
        );
        $pid = wp_insert_post($new_post);                   // insert the post

        if(isset($extrakosten[$i]) && $pid > 0){
            wp_set_post_terms( $pid, $extrakosten[$i],'kostenpost',false);
        }
        if(isset($vergoeding[$i]) && $pid > 0){
            wp_set_post_terms( $pid, $vergoeding[$i],'vergoedingaanleg',false);
        }

    } // close for loop

}

It looks like you where inserting an array of terms in each wp_set_post_terms(). I try to add a string instead in the above code example.

ps: It is not clear why you use count($vergoeding) if you want only two inserted posts? So it looks like this array is supposed to include 2 items.
