Additional image field in WooCommerce category - php

Question

With help i've made custom field on WooCommerce's category, but i want to make it media field (to pick cover image and upload directly from form).
I'm using "How do I add custom fields to the categories in Woocommerce?"
// Add term page
function custom_product_taxonomy_add_new_meta_field() {
// this will add the custom meta field to the add new term page
?>
<div class="form-field">
<label for="term_meta[category_cover]"><?php _e( 'Category Cover', 'category-cover' ); ?></label>
<input type="text" name="term_meta[category_cover]" id="term_meta[category_cover]" value="">
<p class="description"><?php _e( 'Enter a value for this field','category-cover' ); ?></p>
</div>
<?php
}
add_action( 'product_cat_add_form_fields', 'custom_product_taxonomy_add_new_meta_field', 10, 2 );
// Edit term page
function custom_product_taxonomy_edit_meta_field($term) {
// put the term ID into a variable
$t_id = $term->term_id;
// retrieve the existing value(s) for this meta field. This returns an array
$term_meta = get_option( "taxonomy_$t_id" ); ?>
<tr class="form-field">
<th scope="row" valign="top"><label for="term_meta[category_cover]"><?php _e( 'Category Cover', 'category-cover' ); ?></label></th>
<td>
<input type="text" name="term_meta[category_cover]" id="term_meta[category_cover]" value="<?php echo esc_attr( $term_meta['category_cover'] ) ? esc_attr( $term_meta['category_cover'] ) : ''; ?>">
<p class="description"><?php _e( 'Enter an URL for category cover','category-cover' ); ?></p>
</td>
</tr>
<?php
}
add_action( 'product_cat_edit_form_fields', 'custom_product_taxonomy_edit_meta_field', 10, 2 );
// Save extra taxonomy fields callback function.
function save_taxonomy_custom_meta( $term_id ) {
if ( isset( $_POST['term_meta'] ) ) {
$t_id = $term_id;
$term_meta = get_option( "taxonomy_$t_id" );
$cat_keys = array_keys( $_POST['term_meta'] );
foreach ( $cat_keys as $key ) {
if ( isset ( $_POST['term_meta'][$key] ) ) {
$term_meta[$key] = $_POST['term_meta'][$key];
}
}
// Save the option array.
update_option( "taxonomy_$t_id", $term_meta );
}
}
add_action( 'edited_product_cat', 'save_taxonomy_custom_meta', 10, 2 );
add_action( 'create_product_cat', 'save_taxonomy_custom_meta', 10, 2 );
