foreach varaiable as array

[troshan]

Following code generate a select dropdown field
 

$fields['shipping']['shipping_city'] = array(
    'label'       => __('City', 'woocommerce'),
    'placeholder' => _x('', 'placeholder', 'woocommerce'),
    'required'    => true,
    'clear'       => true,
    'type'        => 'select',
    'class'       => array('own-css-name'),
    'options'     => array(
        'New_York_City' => __('New York City', 'woocommerce' ),
        'Chicago' => __('Chicago', 'woocommerce' ),
        'Dallas' => __('Dallas', 'woocommerce' )
        )
    );

I want to get the "option =>" values from category array. I tried the following

$categories = get_categories( $args );
    foreach ($categories as $category) {
    $cityArray[] = "'".$category->slug."' => __('".$category->name."', 'woocommerce' )";
    }
    $fields['shipping']['shipping_city2'] = array(
        'label'       => __('City', 'woocommerce'),
        'placeholder' => _x('', 'placeholder', 'woocommerce'),
        'required'    => true,
        'clear'       => true,
        'type'        => 'select',
        'class'       => array('own-css-name'),
        'options'     => array(implode( ', ', $cityArray ) )
 );

but It return the attached result

Unfortunately that's quite wrong. The "options" needs to be an array where the keys are what you want the value of each to be, and the value is what shows up as the label for it. What you're doing is

1. Taking the array of categories

2. Making another array where each value is a string of PHP code

3. implode()ing the array so that it's only one string with comma separators

4. Sticking that into an array

 

The $cityArray needs to be formed correctly. $category->slug should be the key and the translated $category->name should be the array value.

$cityArray[$category->slug] = __($category->name, 'woocommerce');

Then don't do anything else to it. Just use it as the "options". No array(), no implode().
