Populate array from another array

[jarvis]

Hi,

 

Am hoping someone can help/point me in the right direction!

 

I have the following code:

	$checkout_fields['order']['categories'] = array(
		'type'        => 'select',
		'class'         => array('my-field-class form-row-wide'),	
		'label'       => __('Food options', 'woocommerce'),
		'placeholder' => _x('', 'placeholder', 'woocommerce'),
		'required'    => false,
		'clear'       => false,
		'options'     => array(
			'eat-meat' => __('I eat maet', 'woocommerce' ),
			'not-meat' => __('Meat is gross', 'woocommerce' )
		)
	);	

However, I'd like to make the options part dynamic and therefore grab the values from elsewhere. So I then have this code:

$categories = get_field( 'categories', 'options' );
$choices = array();
if ( is_array( $categories ) ) {

	$category_str = array();
	foreach ( $categories as $category ) {
		
		#echo $category['value'];
		#echo $category['label'];
		
		$category['value'];
		$category['label'];
		$category_str[] = $category['value'].$category['label'];
	
	}
	
	$result = implode(",",$category_str);
	echo $result;
}

My issue is I'm not sure on the best way to amalgamate the two?

 

Can someone help?

Ok, I've managed to get somewhere but struggling with one part now. So I now have:

$categories = get_field( 'categories', 'options' );
$choices = array();
if ( is_array( $categories ) ) {

	$category_str = array();
	foreach ( $categories as $category ) {
		
		$category['value'];
		$category['label'];
		$category_str[$category['value']] = $category['label'];
	
	}
	
}

	$checkout_fields['order']['categories'] = array(
		'type'        => 'select',
		'class'         => array('my-field-class form-row-wide'),	
		'label'       => __('Food options', 'woocommerce'),
		'placeholder' => _x('', 'placeholder', 'woocommerce'),
		'required'    => false,
		'clear'       => false,
		'options' 	  => array_values($category_str)	
	);	

If I use print_r($category_str); I see the following:

Array
(
    [a] => A
    [b] => B
    [c] => C
)

Yet if I view the drop down it shows:

<option value="0">A</option>
<option value="1">B</option>
<option value="2">C</option>

So how do I get the value to be the value from the first array? So it's like this:

<option value="a">A</option>
<option value="b">B</option>
<option value="c">C</option>

Thanks

What does the code for creating the <option> tags look like?

Change

'options'      => array_values($category_str)

to

'options'      => $category_str;

Hi @cyberRobot

 

It's Wordpress/WooCommerce so it's simply a function/hook:

function prg_woocommerce_checkout_fields( $checkout_fields = array() ) {

	$checkout_fields['order']['categories'] = array(
		'type'			=> 'select',
		'class'			=> array('my-field-class form-row-wide'),	
		'label'			=> __('Categories', 'woocommerce'),
		'placeholder'	=> _x('', 'placeholder', 'woocommerce'),
		'required'		=> false,
		'clear'			=> false,
		'options'		=> array_values($category_str)

	);			

	return $checkout_fields;

}

If I manually add the option:

		'options'     => array(
			'eat-meat' => __('I eat meat', 'woocommerce' ),
			'not-meat' => __('Meat is gross', 'woocommerce' )
		)

Then the drop down creates correctly:

<option value="eat-meat">I eat meat</option>
<option value="not-meat">Meat is gross</option>
						

But once I try to make it dynamic by passing values from elsewhere, it just doesn't quite display the right output

 

Does that help?

Thanks @Barand!
