Hello.<\/p>\n

I would like to switch required fields depending on the value of a radio button.<\/p>\n

I prepare fields like this:<\/p>\n

\n[radio my-data-size use_label_element default:1 "Less than 2MB" "More than 2MB"]\n\n[file my-data filetypes:pdf limit:2mb]\n\n\n\n<\/code><\/pre>\n
And I add the code bellow:<\/p>\n
\nfunction wpcf7_validate_customize($result,$tags){\n\n  foreach( $tags as $tag ){\n\t\n    $type = $tag['type'];\n    $name = $tag['name'];\n\n    switch($type){\n      case radio:\n      case 'radio*':\n        if($name === 'my-data-size'){\n          if($_POST[$name] === 'Less than 2MB'){\n            if (is_null($_POST['my-data'])) {\n              $result->invalidate( 'my-data','You need to upload a file' );\n            }\n          } elseif($_POST[$name] === 'More than 2MB') {\n            if ($_POST['my-data-url'] === "") {\n              $result->invalidate( 'my-data-url','You need to note a download URL' );\n            }\n          }\n        }\n        break;\n    }\n\n  }\n  return $result;\n}\n\nadd_filter('wpcf7_validate', 'wpcf7_validate_customize', 11, 2);\n<\/code><\/pre>\n
I would like to rule as below:<\/p>\n
– When you chose “Less than 2MB”, then “my-data” is “required”.
\n– When you chose “More than 2MB”, then “my-data-url” is “required”.<\/p>\n
But
\nWhen I upload a file and submit a form, “You need to upload a file” is shown.<\/p>\n
Could you give me some advice?<\/p>\n","protected":false},"template":"","class_list":["post-14692221","topic","type-topic","status-publish","hentry"],"jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic\/14692221","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":1,"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic\/14692221\/revisions"}],"predecessor-version":[{"id":14692228,"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/topic\/14692221\/revisions\/14692228"}],"wp:attachment":[{"href":"https:\/\/wordpress.org\/support\/wp-json\/wp\/v2\/media?parent=14692221"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
