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(
