Ladies and gents,<\/p>\n

I’m working on a widget and in that widget I want a few <select> fields and a few URL fields. In the example I’m going to give, you see the URL fields. I want to put those fields in an array and place that in the DB and read that same array out again.<\/p>\n

I’m not sure what I’m doing wrong, but all the fields get the value ‘array’ now.<\/p>\n

<?php\nfunction form($instance) {\n        $url = esc_attr($instance['url']);\n        for($i=0;$i<5;$i++) {\n        ?>\n        <p>\n            <?php print_r($url); ?>\n\t\t\t<label for="<?php echo $this->get_field_id('url'); ?>"><?php _e('URL:'); ?>\n\t\t\t\t<input class="widefat" id="<?php echo $this->get_field_id('url'); ?>-<?php echo $i; ?>" name="<?php echo $this->get_field_name('url'); ?>[]" type="text" value="<?php echo $url; ?>" \/>\n\t\t\t<\/label>\n\t\t<\/p>\n\t<?php\n        }\n        ?><\/code><\/pre>\n
<?php\nfunction update($new_instance,$old_instance) {\n\t\t$instance = $old_instance;\n\n        for($i=0;$i<5;$i++) {\n            $instance['url'] = esc_attr($new_instance['url']);\n        }\n\n\t\treturn $instance;\n\t}\n?><\/code><\/pre>\n
I hope some one can give me a shove in the right direction.<\/p>\n
Thanks<\/p>\n","protected":false},"template":"","class_list":["post-2814282","topic","type-topic","status-closed","hentry","topic-tag-array","topic-tag-widget"],"jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic\/2814282","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic"}],"about":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic\/2814282\/revisions"}],"wp:attachment":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/media?parent=2814282"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
