这是我的问题，我安装了WordPress的联系表单7，在我调用API的wpcf7_before_send_mail期间，如果API返回错误，我需要使表单无效，然后我需要使请求无效并返回从API调用传回的错误。
我在 API 失败时将标志设置为 false，并且错误消息也被存储，但尽管我诱导了失败，但我的表单仍然成功。
add_action("wpcf7_before_send_mail", "wpcf7_send_contact_builder");
function wpcf7_send_contact_builder($form) {
$submission = WPCF7_Submission::get_instance();
$wpcf7_data = $submission->get_posted_data();
... api call and set $success to true if ok and false if not ...
if (!$success) {
$form->status = 'validation_failed (statuscode:' . $xml->status->statuscode[0] . ').';
$form->valid = false;
$form->response = $xml->status->statusdesc[0];
return $forml
}
}
我也尝试使用：
$form->invalidate('validation_failed (statuscode:' . $xml->status->statuscode[0] . ').', $xml->status->statusdesc[0]);
但是，无论哪种方式，我都无法阻止发送成功电子邮件并且表单验证为成功。调试证明 if 语句中的 ！success 是有效的，并且包含的代码被添加到变量中。我也尝试好像表单是一个数组（$form['valid'] = false），但这也没有用，表单提交为成功。对我在这里错过了什么有什么想法吗？我省略了 API 调用本身的代码和确定正确的表单 id，这两者都可以正常工作，只有我想要的表单被解析并且 API 调用返回预期数据。
我需要同样的东西。浏览完CF7插件文件后，我找到了以下解决方案：
//To make it working, we must need at least CF7-v5.0;
add_action( 'wpcf7_before_send_mail', 'cf7_validate_api', 15, 3 );
function cf7_validate_api($cf7, &$abort, $submission){
if ( $cf7->id() !== 789 ) //CF7 post-id from admin settings;
return;
$errMsg = '';
//$submission = WPCF7_Submission::get_instance();
$postedData = $submission->get_posted_data();
//$postedData['more-data'] = 'something';
unset($postedData['not-sending-data']);
//-----API posting------
$url = "http://my-web.com/wp-admin/admin-ajax.php?action=get-something";
$username = 'apiUserName';
$password = 'apiUserPass';
$args = [
'headers' => [
'Authorization' => "Basic ".base64_encode( $username . ':' . $password ),
'Accept' => 'application/json; charset=utf-8', // The API returns JSON
//'Content-Type' => 'application/json; charset=utf-8'
],
'body' => $postedData
];
$response = wp_remote_post( $url, $args );
//------------------
if( is_wp_error( $response ) ){
$error_message = $response->get_error_message();
$errMsg = "Something went wrong:'n{$error_message}";
} else {
$response_body = wp_remote_retrieve_body( $response );
$data = json_decode( $response_body );
if( empty($data) || $data->status==0 ){ //API validation error!
$errMsg = $data->msg->title."'n".$data->msg->description;
}
}
if( $errMsg ){ //do not send mail;
//$cf7->skip_mail = true; //for older versions!
$abort = true; //==> Here, it is with 'called by reference' since CF7-v5.0 :)
$submission->set_status( 'validation_failed' );
//$submission->set_response( $cf7->message( 'validation_error' ) ); //msg from admin settings;
$submission->set_response( $cf7->filter_message($errMsg) ); //custom msg;
}
}
希望它能帮助某人。快乐编码:)
