woocommerce_form_field pass array to select options

Hi, I’m trying to add a custom select field to the checkout page and I’m using the function woocommerce_form_field to add one.

I’m trying to pass an array to the options so that I don’t have to manually write all the possible options.

Here is the code I currently have (which doesn’t work).
```
woocommerce_form_field( 'store_selection', array(
        'type'          => 'select',
        'class'         => array('my-field-class form-row-wide'),
        'label'         => __('Fill in this field'),
        'placeholder'   => __('Enter something'),
        'options'		=> array($stores['value'] => $stores['option']),
        ), $checkout->get_value( 'store_selection' ));
```
It’s this part that I don’t get how to use properly:
‘options’ => array($stores[‘value’] => $stores[‘option’]),

Can anyone help with this issue?

Thanks!

EDIT:

This is how I fill in my array
```
while ( $loop->have_posts() ) : $loop->the_post();
		$title = get_the_title();
		$email = get_field( 'email', get_the_ID() );
		$postType = get_post_type();
		$obj = get_post_type_object( $postType );
		$singularName = $obj->labels->singular_name;
		$option = $singularName . ' - ' . $title;

		array_push( $stores, array('value' => $email, 'option' => $option) );
		
		//array_push($values, $email);
	endwhile;
```
I’ve tried to use one array for the values and one for the options first but it didn’t worked so I tried with a multidimensional array but it doesn’t work either. It display an empty dropdown.

I’m in the same boat here. I’ve tried the array_push and it won’t take it. I’ve tried to set the option as a variable ie.
```
$hosp = "'options' =>array("
$hosp .= "'" . $hosp_date . "' => __( '" . $hosp_date ."' ),";
$hosp .= "),";
```
and it just produces an error.

I can’t seem to find anything on how to push variables into the options…

Had exactly the same problem here then I realised the issue – instead of using 0-based indexing of the arrays, it requires an associative array with named keys, thus;

using the example from @cocosay, the array was like this
```
array_push( $stores, array('value' => $email, 'option' => $option) 
```
but needs to be constructed like this, within a loop, as it will build up the array of options and values with named keys rather than 0,1,2 etc
```
$stores[$email] = $option;
```
The same is also true if passing other arrays to this function, such as custom_attributes
