[英]Ajax success and error
I am using Ajax to post the results from a php form to a database using an API. 我正在使用Ajax使用API将结果从php表单发布到数据库。 However when the script runs, I am not getting anything in return stating that it was a success or an error.
但是,当脚本运行时,我没有得到任何回报,说明它是成功还是错误。 I can log into the database and see that it has added the entry but I am not getting an alert when it saves to the database.
我可以登录数据库,看到它已经添加了条目,但是当它保存到数据库中时我没有收到警报。
What I would like the script to do is: 我希望脚本执行的操作是:
-First save to the database (Done) -首先保存到数据库(完成)
-Second: Alert the user that the operation was completed successfully or error -第二:向用户警告该操作已成功完成或出错
-Third: reset the values in the form if success, keep values if error -第三:如果成功,则重置表单中的值,如果错误,则保留值
Here is what I have tried and have so far: 到目前为止,这是我尝试过的事情:
$(document).ready(function () {
function showSuccess(message) {
$('#success.success').append('<h3 class="alert alert-success">' + message + '</h3>').fadeIn(1000).fadeOut(5000);
}
function showError(message) {
$('#success.success').append('<h3 class="alert alert-danger">' + message + '</h3>').fadeIn(1000).fadeOut(5000);
}
$('form#directory-create').on('submit', function (e) {
//stops the submit action
e.preventDefault();
//format the data into javascript object
var data = $(this).serializeArray();
//calls function to create record, passing participant information as arguments
createRecord(data);
});
function resetStudyInfo() {
//resets all form values to default
$('form#directory-create').find('input:text, input:radio, input:email, input:phone').val('');
return true;
}
function createRecord(data) {
//converts into json data format
var myData = JSON.stringify(data);
console.log(myData);
$.ajax({
//setup option for .ajax func
type: "POST",
url: "directory-create-record.php",
data: {
//user_data : contains all the fields and their data
user_data: myData
},
//shows output message on error or success
success: function () {
showSuccess('Study created successfully, you may now add participants to this study.');
var reset = resetStudyInfo();
return true;
},
error: function () {
showError('Unable to create the study, did you fill out everything?');
return false;
}
});
}
});
PHP side: PHP方面:
require "RestCallRequest.php";
function insertData($data_from_user){
$status = 2;
$url = "xxxx";
$token = "mytokenishere";
$fname = $data_from_user[0]->value;
$lname = $data_from_user[1]->value;
$title = $data_from_user[2]->value;
$school = $data_from_user[3]->value;
$facultystafftrainee = $data_from_user[4]->value;
$email = $data_from_user[5]->value;
$phone = $data_from_user[6]->value;
$record_id = $lname .'_'. $fname;
# an array containing all the elements that must be submitted to the API
$data = "record_id,f_name,l_name,title,school,facultystafftrainee,email,phone,directory_complete\r\n";
$data .= "$record_id,$fname,$lname,$title,$school,$facultystafftrainee,$email,$phone,$status";
$args = array(
'content' => 'record',
'type' => 'flat',
'format' => 'csv',
'token' => $token,
'data' => $data
);
# create a new API request object
$request = new RestCallRequest($url, 'POST', $args);
# initiate the API request
$request->execute();
$result = $request->getResponseBody();
if($result == '1'){
return 1;
}
}
Any help is greatly appreciated. 任何帮助是极大的赞赏。 Thank you
谢谢
When resetting the form values, you have input:email and input:phone, javascript throws a syntax error as you do not need these values, When you remove them your code should work.... Here is the complete working code 重置表单值时,您具有input:email和input:phone,javascript会引发语法错误,因为您不需要这些值,当您删除它们时,您的代码应该可以正常工作。...这是完整的工作代码
$(document).ready(function () {
function showSuccess(message) {
$('#success.success').append('<h3 class="alert alert-success">' + message + '</h3>').fadeIn(1000).fadeOut(5000);
}
function showError(message) {
$('#success.success').append('<h3 class="alert alert-danger">' + message + '</h3>').fadeIn(1000).fadeOut(5000);
