[dynamic_select* subject placeholder:Please select include_blank dtx_disable_blank "CF7_POST key='subject_name'" "Subject example 1" "Subject example 2" "Subject example 3" "Subject example 4" "Subject example 5"]

Code used for the Form action button:

<form action="https://example.com/contactform/" method="post">
<input type="hidden" name="subject_name" value="Subject example 3">
<button name="Kontakt" title="Kontakt aufnehmen">Kontakt aufnehmen</button>
</form>

It would be great if you could help me here by giving me a functional example of how the code should look correctly and what needs to be written in the functions.php.

Thanks so much

Best regards

I’m encountering an issue with a select field dynamically populated using a custom function. The select field is populated correctly, but in the email sent, the values assigned to the [select_dynamic] and [_raw_select_dynamic] tags are identical.

After conducting various tests, I noticed that if I manually insert the post ID in the line of code “$date_corso = get_field('date_del_corso', get_the_ID());" making it, for example, “$date_corso = get_field('date_del_corso', 9863);“, everything works perfectly, and the values in the email are correctly submitted.

Of course, I’ve already verified that the value returned by get_the_ID() is correct.

Here’s the entire code:

function dynamic_select_field_values ( $scanned_tag, $replace ) {  

    if ( $scanned_tag['name'] != 'select_dynamic' )  
        return $scanned_tag;

    $date_corso = get_field('date_del_corso', get_the_ID());

    if (isset($date_corso)) {
        foreach ($date_corso as $d) {
            $today = strtotime(date('Ymd'));
            $data = get_field('data_corso', $d);
            $location = get_field('location_corso', $d);
            $timestamp = strtotime($data);
            setlocale(LC_TIME, 'it_IT.utf8');
            $giorno_testuale = ucfirst(strftime('%A', $timestamp));
            $giorno_numerico = date('d', $timestamp);
            $mese_testuale = ucfirst(strftime('%B', $timestamp));
            $anno_numerico = date('Y', $timestamp);
            $option = $giorno_numerico . " " . $mese_testuale . " " . $anno_numerico . " - " . $location;
            
            if($today < strtotime($data)) {
                $scanned_tag['raw_values'][] =  $d . '|' .  $option;
            }
        }
    }

    $pipes = new WPCF7_Pipes($scanned_tag['raw_values']);
    $scanned_tag['labels'] = $pipes->collect_afters(); // this is the html info for each option
    $scanned_tag['pipes'] = $pipes; // this is separator
    $scanned_tag['values'] = $pipes->collect_befores(); // this is the value for each option

    return $scanned_tag;  
}  

add_filter( 'wpcf7_form_tag', 'dynamic_select_field_values', 10, 2); 

Thank you in advance for your help and suggestions!

[dynamic_select licencie id:licencie class:select "source:filter"]

And here is the full code snippet:

add_filter( 'cf7sg_custom_dynamic_select','licencie_dynamic_options',10,3);
function licencie_dynamic_options($options, $tag, $cf7_key){
  if('form-1'!==$cf7_key || 'licencie' !== $tag->name){
    return $options;
  }
  global $wpdb;
  $sql = "SELECT id, CONCAT(firstname, ' ', lastname) AS fullname FROM {$wpdb->prefix}_mytable";
  $datas = $wpdb->get_results($sql);
	foreach($datas as $row){
		$data[$row->id] = $row->fullname;
	}
  foreach($data as $value=>$label){
    $options[$value]=$label;
  }
  return $options;
}

But I can’t get values, all I get is the first letter of fullname. What did I missed? Shall I return a json array instead of a PHP one?

If I display $options (var_export), I have this:

array (
  1 => 'John Doe',
  2 => 'Mary Doe',
)

But in my form, there is:

<select value="" id="licencie" name="licencie" class="wpcf7-form-control cf7sg-dynamic-list cf7sg-dynamic_select wpcf7-dynamic_select select">
<option value="1">J</option>
<option value="2">M</option>
</select>

Can you help me please?

<select id="select">
  <option value="1" data-foo="dogs">this</option>
  <option value="2" data-foo="cats">that</option>
  <option value="3" data-foo="gerbils">other</option>
</select>

$choices = array(
‘– Make a Selection –‘ => ”,
value_1 => array( ‘Element 1’, ‘optgroup_1’ ),
value_2 => array( ‘Element 2’, ‘optgroup_1’ ),
value_3 => array( ‘Element 3’, ‘optgroup_1’ ),
value_4 => array( ‘Element 4’, ‘optgroup_2’ ),
value_5 => array( ‘Element 5’, ‘optgroup_2’ ),
value_6 => array( ‘Element 6’, ‘optgroup_3’ ),
value_7 => array( ‘Element 7’, ‘optgroup_3’ ),
);

This could also lead to improve the dropdown adding the possibility of more customisation for each element:

value => array( ‘Label’, ‘optgroup’, ‘class string’, ‘id’, ‘javascript’ ),

Thanks in advance for your great plugin.

I’m going to try modifying the code shared in the categories dropdown thread; and am going to wait for a reply on the subcategories thread as I also want to show parent-child relationships among the terms in my taxonomy.
