I have created two text fields that will display on a registration form.
After the registration based on these two text fields I want to display their values as a select field.
Is this possible? Is there a way to create a select field which will take choices based on another fields values?
I can display these fields on a select field with the following code but the problem here is that I cannot save the choise value.
<select name="cars" id="cars">
<option value=" <?php the_field('car_type_1'); ?> " > <?php the_field('car_type_1'); ?> </option>
<option value=" <?php the_field('car_type_2'); ?> " > <?php the_field('car_type_2'); ?> </option>
</select>
After doing some research I think that the best way to achieve this is by creating a repeater field with a text subfield.
The question now is how can I display this repeater field as a select field with the values of the text subfields and how can I save the value from the select field choise (the repeater field will display in a registration form).
UPDATE
So I’ve managed to display the repeater field as a select box with the following code
<select name="cars" id="cars">
<?php
// Check rows existexists.
// Loop through rows.
while( have_rows('yacht_type1') ) : the_row();
// Load sub field value.
$sub_value = get_sub_field('name');
// Do something...
echo '<option value="'.$sub_value.'">'.$sub_value.'</option>';
endwhile;
?>
</select>
Now what I’m actually searching for is how to get and store the value from the select box.
I’m not sure I understand completely what you are trying to do, so this may or may not be helpful.
Created an options page. On the options page you have a repeater with a text sub field. You enter all of the possible values that you want in the select field. Then you create a select field where you want to use these values and you dynamically populate the choices.
Actually you helped a lot.
I was trying to populate the choises from a field group that was showing on users.
Is it possible to do this on a field group that is showing somewhere else besides options page?
I’m trying to show this field group on users panel but the populate functions doesn’t work there.
Finally, I’ve managed to succesfully populate the repeater field in a select field in every users panel with this function
function acf_load_select_field_field_choices($field) {
global $current_user;
//Get the repeater field values
$choices = get_field('repeater_field_name',$current_user);
$field['choices'] = [];
// loop through array and add to field 'choices'
if (is_array($choices)) {
foreach ($choices as $choice) {
//Set the select values
$field['choices'][$choice['subfield']] = $choice['subfield'];
}
}
// return the field
return $field;
}
add_filter('acf/load_field/name=select_field', 'acf_load_select_field_field_choices');
The only problem that I’m facing right now is that the select field doesn’t update when submitting a form.
The code that I’m using to display and update the select field is the following
<?php
$field = get_field_object('repeater_field_key');
if (!empty($field['choices'])) { ?>
<select>
<?php foreach ($field['choices'] as $v => $l) { ?>
<option value="<?php echo $v; ?>"><?php echo $l; ?></option>
<?php } ?>
</select>
<?php }
$current_user_id = get_current_user_id();
update_field($field, $field['value'], 'user_'.$current_user_id);
?>
What am I doing wrong?
