php - Display Events with Form Submit (FullCalendar)

Good day!
I am working on a small personal project with FullCalendar. So in the code below, I have written a function that displays the events when the user searches for that event when a keyword is entered. (e.g. "meeting")
function load($pdo)
{
try {
if (isset($_POST['search'])) {
//run sql connection and query
$term = $_POST['term'];
$data = array();
$sql = "SELECT * FROM events WHERE keyword LIKE '%$term%'";
$stmt = $pdo->prepare($sql);
$stmt->execute();
$result = $stmt->fetchAll();
//output events data from db in array using foreach loop
foreach ($result as $row) {
$description = $row['description'];
$sentence = preg_replace('/(.*?[?!.](?=\s|$)).*/', '\\1', $description);
if (($row['allDay'] == '1') == 1) {
$data[] = array(
'id' => $row["id"],
'title' => $row["title"],
'start' => $row["s_date"],
'description' => $sentence,
'end' => $row["e_date"],
'url' => "event.php?id=".$row['id'],
'backgroundColor' => $row['bg_color'],
'borderColor' => $row['brdr_Color'],
'keywords' => $row['keyword'],
'category' => $row['category']
);
} else {
$data[] = array(
'id' => $row["id"],
'title' => $row["title"],
'start' => $row["s_date"],
'description' => $sentence,
'end' => $row["e_date"],
'url' => "event.php?id=".$row['id'],
'backgroundColor' => $row['bg_color'],
'borderColor' => $row['brdr_Color'],
'keywords' => $row['keyword'],
'category' => $row['category']
);
}
}
//echo and convert array to JSON representation
echo json_encode($data);
}
} catch (PDOException $e) {
echo "Connection failed: " . $e->getMessage();
}
}
//execute load function
load($pdo);
The results are echoed in a json_encoded function and are loaded from jQuery.
$(document).ready(function () {
var calendar = $("#calendar").fullCalendar({
displayEventTime: false,
editable: false,
header: {
left: "prev,next today",
center: "title",
right: "listMonth, month,agendaWeek,agendaDay",
},
eventRender: function (event, element, view) {
$(element).tooltip({
title: event.description,
});
},
events: "load.php",
});
});
After submitting the form/hitting the submit button, the events are not returned or displayed. Is there something I'm missing in my code, or am I missing a procedure?
I hope I described my issue to your best of understanding and I hope to learn from this and better improve my code in the future.

How to return ajax with separate API URL response to controller in YII2?

I am trying to call a API URL using AJAX. I need to validate the response and update the DB, SO I need to return it to the controller.
Is there any way to do that. Here is my view, JS and controller code.
Here is my View Code where I have a separate URL for validation, which is the API URL
View
<?php $form = ActiveForm::begin([
'action' => ['users/renderstep3'],
'validationUrl' => 'API URL',
'options' => [
'class' => 'comment-form'
]
]); ?>
<?= $form->field($paymentmodel, 'customerId')->hiddenInput(['value'=> $userid])->label(false) ?>
<?= $form->field($paymentmodel, 'owner')->textInput(['maxlength' => true]) ?>
<div class="form-group">
<?= Html::submitButton('Submit', ['class' => 'btn btn-success']) ?>
</div>
<?php ActiveForm::end(); ?>
</div>
JS
jQuery(document).ready(function($) {
$('body').on('submit', '.comment-form', function(event) {
event.preventDefault(); // stopping submitting
var data = $(this).serializeArray();
data.splice(0,1);
var result = {};
for ( i=0 ; i < data.length ; i++)
{
key = data[i].name.replace("UserPaymentDetails[", "").slice(0,-1);
result[key] = data[i].value;
}
var url = $(this).attr('validationUrl');
$.ajax({
url: url,
type: 'post',
dataType: 'json',
data: JSON.stringify(result)
})
.done(function(response) {
return response;
})
.fail(function() {
console.log("error");
});
});
});
Controller Action
public function actionRenderstep3()
{
$model = new Users();
$detailsmodel = new UserDetails();
$paymentmodel = new UserPaymentDetails();
if (Yii::$app->request->isAjax) {
Yii::$app->response->format = \yii\web\Response::FORMAT_JSON;
$data = Yii::$app->request->post();
print_r($data) ; exit;
}
if ($paymentmodel->load(Yii::$app->request->post()) && $paymentmodel->validate())
{
$paymentmodel->Status = 0;
$paymentmodel->save();
return $this->redirect(['index']);
}
return $this->render('renderstep3', [
'model' => $model,
'detailsmodel' => $detailsmodel,
'paymentmodel' => $paymentmodel,
]); }
Thanks in advance!!

In your controller, you have to change the action like this in order to validate using Ajax. I have edited my answer. Please note that you can delete your custom js code in order to use like this.
// ... The View file
<?php
$form = ActiveForm::begin([
'action' => ['users/renderstep3'],
'enableAjaxValidation' => true,
'validationUrl' => 'API URL',
'options' => [
'class' => 'comment-form'
]
]);
?>
<?= $form->field($paymentmodel, 'customerId')->hiddenInput(['value'=> $userid])->label(false) ?>
<?= $form->field($paymentmodel, 'owner')->textInput(['maxlength' => true]) ?>
<div class="form-group">
<?= Html::submitButton('Submit', ['class' => 'btn btn-success']) ?>
</div>
<?php ActiveForm::end(); ?>
// ... Controller
public function actionRenderstep3()
{
$model = new Users();
$detailsmodel = new UserDetails();
$paymentmodel = new UserPaymentDetails();
if (Yii::$app->request->isAjax && $paymentmodel->load(Yii::$app->request->post())) {
Yii::$app->response->format = \yii\web\Response::FORMAT_JSON;
return ActiveForm::validate($model);
}
if ($paymentmodel->load(Yii::$app->request->post())) {
$paymentmodel->Status = 0;
$paymentmodel->save(false); // Validate false, because we did the validation before
return $this->redirect(['index']);
}
return $this->render('renderstep3', [
'model' => $model,
'detailsmodel' => $detailsmodel,
'paymentmodel' => $paymentmodel,
]);
}
You can find more information here
https://www.yiiframework.com/doc/guide/2.0/en/input-validation

<?php
$form = ActiveForm::begin([
'action' => ['users/renderstep3'],
'validationUrl' => 'API URL',//ajax validation hit to validationUrl if provide other wise validationUrl is action Url
'options' => [
'class' => 'comment-form'
]
]);
?>
and change some code in js
the below code calls befor form submit
$('body').on('beforeSubmit', '.comment-form', function(event)
In controller
In case of single model validation
if ($paymentmodel->load(Yii::$app->request->post())) {
if (Yii::$app->request->isAjax) {
Yii::$app->response->format = \yii\web\Response::FORMAT_JSON;
return yii\widgets\ActiveForm::validate($model);
}
$paymentmodel->Status = 0;
if ($paymentmodel->save(false)) {
return $this->redirect(['index']);
}
}
In case of multiple model validation
if ($model->load(Yii::$app->request->post())) {
$detailsmodel->load(Yii::$app->request->post());
$paymentmodel->load(Yii::$app->request->post());
if (Yii::$app->request->isAjax) {
Yii::$app->response->format = \yii\web\Response::FORMAT_JSON;
$return = yii\widgets\ActiveForm::validate($model);
$return = \yii\helpers\ArrayHelper::merge(yii\widgets\ActiveForm::validate($detailsmodel), $return);
$return = \yii\helpers\ArrayHelper::merge(yii\widgets\ActiveForm::validate($paymentmodel), $return);
return $return;
}
//here is data saving or logic
}

Woocommerce API connection to place order button

I am trying to connect to an api using the code below, so when the customer clicks on the "place order" button on the Woocommerce checkout page, I am getting a "please try again" error:
var amount = <?php global $woocommerce; print WC()->cart->total; ?>;
var merchantOrderId = '<?php echo print time(); ?>';
var apiKey = 'm85BXXLpf_icrSvqbElR11xquEgmKZ8wfeRb2ly3-G7pIwCKDuytgplB7AQGi-5t';
renderMMoneyPaymentButton(amount, merchantOrderId, apiKey);
I am trying to pass this information to the api via this function but I am not getting a successful connection.
public function process_payment( $order_id ) {
global $woocommerce;
// we need it to get any order detailes
$order = new WC_Order($order_id);
/*
* Array with parameters for API interaction
*/
$args = array(
'amount' => '<?php global $woocommerce; print WC()->cart->total; ?>',
'merchant_order_id' => '<?php print time(); ?>',
'api_Key' => 'm85BXXLpf_icrSvqbElR11xquEgmKZ8wfeRb2ly3-G7pIwCKDuytgplB7AQGi-5t',
'currency' => 'BBD',
);
/*
* Your API interaction could be built with wp_remote_post()
*/
$response = wp_remote_post( 'https://api.mmoneybb.com/merchant/js/mmoney-payment.js', $args );
if( !is_wp_error( $response ) ) {
$body = json_decode( $response['body'], true );
// it could be different depending on your payment processor
if ( $body ['$response'] == 'APPROVED') {
// we received the payment
$order->payment_complete();
$order->reduce_order_stock();
// some notes to customer (replace true with false to make it private)
$order->add_order_note( 'Thanks for your payment!!!!', true );
// Empty cart
$woocommerce->cart->empty_cart();
// Redirect to the thank you page
return array(
'result' => 'success',
'redirect' => $this->get_return_url( $order )
);
} else {
wc_add_notice( 'Please try again.', 'error' );
return;
}
} else {
wc_add_notice( 'Connection error.', 'error' );
return;
}
}
let me know what i am doing wrong much appreciated also this is the other script as well
function renderMMoneyPaymentButton(amount, merchantOrderId, apiKey) {
let paymentParams = {
amount: amount,
api_key: apiKey,
currency: 'BBD',
merchant_order_id: merchantOrderId,
onCancel: function () { console.log('Modal closed'); },
onError: function(error) { console.log('Error', error); },
onPaid: function (invoice) { console.log('Payment complete', invoice); }
};
// "mMoney" window global provided by sourcing mmoney-payment.js script.
// Attach the button to the empty element.
mMoney.payment.button.render(paymentParams, '#mmoney-payment-button');
}

1) In your first snippet code you are using javascript and you need to get the order Id and then the order total… You can only get the Order ID after the order is placed…
There is an answer example here.
2) Your 2nd public function involves only PHP… There are some errors and mistakes in this code. Try the following revisited code instead:
public function process_payment( $order_id ) {
// Get The WC_Order Object instance
$order = wc_get_order( $order_id );
/*
* Array with parameters for API interaction
*/
$args = array(
'amount' => $order->get_total(),
'merchant_order_id' => $order_id,
'api_Key' => 'm85BXXLpf_icrSvqbElR11xquEgmKZ8wfeRb2ly3-G7pIwCKDuytgplB7AQGi-5t',
'currency' => $order->get_currency(),
);
/*
* Your API interaction could be built with wp_remote_post()
*/
$response = wp_remote_post( 'https://api.mmoneybb.com/merchant/js/mmoney-payment.js', $args );
if( !is_wp_error( $response ) ) {
$body = json_decode( $response['body'], true );
// it could be different depending on your payment processor
if ( $body ['$response'] == 'APPROVED') {
// we received the payment
$order->payment_complete();
$order->reduce_order_stock();
// some notes to customer (replace true with false to make it private)
$order->add_order_note( 'Thanks for your payment!!!!', true );
// Empty cart
$woocommerce->cart->empty_cart();
// Redirect to the thank you page
return array(
'result' => 'success',
'redirect' => $this->get_return_url( $order )
);
} else {
wc_add_notice( 'Please try again.', 'error' );
return;
}
} else {
wc_add_notice( 'Connection error.', 'error' );
return;
}
}
It should better work.

How to use ajax for login form

I am currently creating a login form in PHP PDO and I am using ajax to display the relevant messages on screen, e.g.
"Logging in..."
"Some input fields are empty"
"Your username is required"
"Your password is required"
Validation such as checking if input fields are empty is working fine along with when login credentials appear to be incorrect however when I login with correct credentials I just get message "Logging in..." and nothing happens, I don't even think it sets the session. I have also added a token to prevent CSRF and was just wondering if i'm using it correctly.
I'm unsure of what is causing my code not to proceed with logging in.
my ajax script:
<script type='text/javascript'>
$(document).ready(function () {
var submitButton = $("#btn-login");
submitButton.on('click', function (e) {
e.preventDefault();
// Get input field values of the contact form
var loginFormInputs = $('#login-form :input'),
userName = $('#txt_uname_email').val(),
userPassword = $('#txt_password').val(),
token = $('#token').val(),
alertMessage = $('#login-alert-message');
// Disable Inputs and display a loading message
alertMessage.html('<p style="opacity: 1"><i class="fa fa-spinner fa-spin text-success"></i> Logging in..</p>');
submitButton.html('<i class="fas fa-spinner fa-spin"></i>');
loginFormInputs.prop("disabled", true);
// Data to be sent to server
var post_data = {
'form': 'loginForm',
'userName': userName,
'userPassword': userPassword,
'token': token
};
// Ajax post data to server
$.post('./api', post_data, function (response) {
// Load jsn data from server and output message
if (response.type === 'error') {
alertMessage.html('<p><i class="fa-lg far fa-times-circle text-danger"></i> ' + response.text + '</p>');
submitButton.html('Login');
loginFormInputs.prop("disabled", false);
} else {
alertMessage.html('<p><i class="fa-lg far fa-check-circle text-success"></i> ' + response.text + '</p>');
submitButton.html('Login');
window.location = "dashboard";
}
}, 'json');
});
});
</script>
My login function (class.user.php) which is used in api.php:
public function doLogin($uname,$umail,$upass)

$userRow=$stmt->fetch(PDO::FETCH_ASSOC);

Autocompleting a form in PHP/Javascript

I have been trying to make an autocomplete script for the whole day but I can't seem to figure it out.
<form method="POST">
<input type="number" id="firstfield">
<input type="text" id="text_first">
<input type="text" id="text_sec">
<input type="text" id="text_third">
</form>
This is my html.
what I am trying to do is to use ajax to autocomplete the first field
like this:
and when there are 9 numbers in the first input it fills the other inputs as well with the correct linked data
the script on the ajax.php sends a mysqli_query to the server and asks for all the
data(table: fields || rows: number, first, sec, third)

https://github.com/ivaynberg/select2
PHP Integration Example:
<?php
/* add your db connector in bootstrap.php */
require 'bootstrap.php';
/*
$('#categories').select2({
placeholder: 'Search for a category',
ajax: {
url: "/ajax/select2_sample.php",
dataType: 'json',
quietMillis: 100,
data: function (term, page) {
return {
term: term, //search term
page_limit: 10 // page size
};
},
results: function (data, page) {
return { results: data.results };
}
},
initSelection: function(element, callback) {
return $.getJSON("/ajax/select2_sample.php?id=" + (element.val()), null, function(data) {
return callback(data);
});
}
});
*/
$row = array();
$return_arr = array();
$row_array = array();
if((isset($_GET['term']) && strlen($_GET['term']) > 0) || (isset($_GET['id']) && is_numeric($_GET['id'])))
{
if(isset($_GET['term']))
{
$getVar = $db->real_escape_string($_GET['term']);
$whereClause = " label LIKE '%" . $getVar ."%' ";
}
elseif(isset($_GET['id']))
{
$whereClause = " categoryId = $getVar ";
}
/* limit with page_limit get */
$limit = intval($_GET['page_limit']);
$sql = "SELECT id, text FROM mytable WHERE $whereClause ORDER BY text LIMIT $limit";
/** #var $result MySQLi_result */
$result = $db->query($sql);
if($result->num_rows > 0)
{
while($row = $result->fetch_array())
{
$row_array['id'] = $row['id'];
$row_array['text'] = utf8_encode($row['text']);
array_push($return_arr,$row_array);
}
}
}
else
{
$row_array['id'] = 0;
$row_array['text'] = utf8_encode('Start Typing....');
array_push($return_arr,$row_array);
}
$ret = array();
/* this is the return for a single result needed by select2 for initSelection */
if(isset($_GET['id']))
{
$ret = $row_array;
}
/* this is the return for a multiple results needed by select2
* Your results in select2 options needs to be data.result
*/
else
{
$ret['results'] = $return_arr;
}
echo json_encode($ret);
$db->close();
Legacy Version:
In my example i'm using an old Yii project, but you can easily edit it to your demands.
The request encodes in JSON. (You don't need yii for this tho)
public function actionSearchUser($query) {
$this->check();
if ($query === '' || strlen($query) < 3) {
echo CJSON::encode(array('id' => -1));
} else {
$users = User::model()->findAll(array('order' => 'userID',
'condition' => 'username LIKE :username',
'limit' => '5',
'params' => array(':username' => $query . '%')
));
$data = array();
foreach ($users as $user) {
$data[] = array(
'id' => $user->userID,
'text' => $user->username,
);
}
echo CJSON::encode($data);
}
Yii::app()->end();
}
Using this in the View:
$this->widget('ext.ESelect2.ESelect2', array(
'name' => 'userID',
'options' => array(
'minimumInputLength' => '3',
'width' => '348px',
'placeholder' => 'Select Person',
'ajax' => array(
'url' => Yii::app()->controller->createUrl('API/searchUser'),
'dataType' => 'json',
'data' => 'js:function(term, page) { return {q: term }; }',
'results' => 'js:function(data) { return {results: data}; }',
),
),
));
The following Script is taken from the official documentation, may be easier to adopt to:
$("#e6").select2({
placeholder: {title: "Search for a movie", id: ""},
minimumInputLength: 1,
ajax: { // instead of writing the function to execute the request we use Select2's convenient helper
url: "http://api.rottentomatoes.com/api/public/v1.0/movies.json",
dataType: 'jsonp',
data: function (term, page) {
return {
q: term, // search term
page_limit: 10,
apikey: "ju6z9mjyajq2djue3gbvv26t" // please do not use so this example keeps working
};
},
results: function (data, page) { // parse the results into the format expected by Select2.
// since we are using custom formatting functions we do not need to alter remote JSON data
return {results: data.movies};
}
},
formatResult: movieFormatResult, // omitted for brevity, see the source of this page
formatSelection: movieFormatSelection // omitted for brevity, see the source of this page
});
This may be found here: http://ivaynberg.github.io/select2/select-2.1.html
You can optain a copy of select2 on the github repository above.
