Cannot pass through tax_input in ACF frontend form

  • I get the following error and white screen of death when I try submit the front end form:

    Warning: Invalid argument supplied for foreach() wp-includes/post.php on line 3471

    The only way I can get a successful submission is to either, be logged in, or remove:

    'tax_input' => 'featured'

    Has anyone else encountered this?

  • This needs to be in the form specified for wp_insert_post() https://codex.wordpress.org/Function_Reference/wp_insert_post
    example

    
'tax_input' => array(
   // taxonomy => terms
   'category' => 'featured'
)

  • Ah, in an array. Thanks!

  • Because the filter pre_save acf has been disabled in the version 5? I need him to handle taxonimias of this model in my post, among several outroso fields I used to save.
    Is there another way of doing?

    This is my code

    function salvar( $post_id ) {

    return $post_id;
    
    echo "<script> alert('Ok Joao'); </script>";

    $field = $_POST['acf'];//resume a chamada do form
    
    $form_type = $field['form_type'];//diz qual é a CTP que deve guardar
    
    // check if this is to be a new post
    if( $post_id != 'new_post' ) {
           
        switch ($form_type) {

            case 'advert':

            //Tratamento das Cidades como Taxonomias

            $exist_state = term_exists( $field['field_569b07ac73afc'], 'estado_cidade' );

            if( $exist_state == 0 && $exist_state == null){

                $state = array(
                    'description'=> 'Encontre anuncios em '. $field['field_569b07ac73afc'] ,
                    'slug' => sanitize_title($field['field_569b07ac73afc']),
                    //'parent'=> $parent_term_id
                );

                $state_save = wp_insert_term($field['field_569b07ac73afc'], 'estado_cidade', $state );

                $state_save = $state_save['term_id'];

            }else{

                 $state_save = get_term_by('id', $field['field_569b07ac73afc'], 'estado_cidade' );
