send uploaded file via phpmailer

I have a form, with a input files element.
I would like to select a file with this element and send it via ajax to antother php file:
** HTML **
<form enctype="multipart/form-data">
<input type="file" id="angebote" name="angebote[]" accept=".pdf" multiple />
</form>
** Script **
var form_data = new FormData();
for (var index = 0; index < $('#angebote').prop('files').length; index++) {
form_data.append("angebote[]", $('#angebote').prop('files')[index]);
}
$.ajax({
url: 'ajax/sendAnforderung.php',
cache: false,
contentType: false,
processData: false,
data: form_data,
type: 'post',
success: function(response){
//...
}
});
** PHP **
print_r($_FILES);
** Result **
Array
(
[angebote] => Array
(
[name] => Array
(
[0] => scan.pdf
)
[type] => Array
(
[0] => application/pdf
)
[tmp_name] => Array
(
[0] => /volume1/#tmp/phpiZrjNh
)
[error] => Array
(
[0] => 0
)
[size] => Array
(
[0] => 509145
)
)
)
Now I would like to send this file as an attachment via php mailer.
for this I nee the path of the file.
I tried this:
echo $_FILES['angebote']['tmp_name'][0].'/'.$_FILES['angebote']['name'][0];
Result:
/volume1/#tmp/phpiZrjNh/scan.pdf
But the file is not be accessable.
Where is my mistake?

How to traverse this ajax response as array?

I am getting the below array as response using ajax in code igniter.
Array
(
[0] => stdClass Object
(
[monthly_count] => 3
)
[1] => stdClass Object
(
[monthly_count] => 1
)
)
//What i have tried so far is
$.ajax({
url:"<?php echo base_url();?>Admins/get_monthly_orders",
type: 'POST',
//dataType: 'JSON',
success:function (data) {
var result = [];
var array = data;
console.log(data);
array.forEach(function(k , v) {
var result = v.monthly_count;
})
console.log(result);
please help me to traverse and get 3, 1
and i need to get the value of 'monthly_count' like this
Array
(
[0] =>3
[1] => 1
)
or better something like this
[3, 1]
my controller code is this
public function get_monthly_orders(){
$monthlyOrders = $this->Admin_model->get_monthly_orders();
if($monthlyOrders){
print_r($monthlyOrders);
}
else{
return false;
}
}

Try changing the print_r($monthlyOrders) to echo json_encode( $monthlyOrders );. This will return it in JSON. It will be much easier to traverse in JS.
Well if you want to traverse it, you can just:
let result = [];
array.forEach(el => {
result.push(el.monthly);
})
console.log(result);

jQuery Ajax Upload File php receives array even with out content

It's working but on every submit I receive an array even tho a file is not even added to the file input (multifile input)
postData = new FormData(this);
$.ajax({
url: "/url",
type: "POST",
data: postData,
cache: false,
contentType: false,
processData: false,
success: function (data, textStatus, jqXHR) {
if (data === "true") {
window.location.replace("/url");
} else {
$(".errors").html(data);
}
},
error: function (jqXHR, textStatus, errorThrown) {
swal("Der opstod en fejl");
}
});
What i get from $_FILES is the following
Array
(
[files] => Array
(
[name] => Array
(
[0] =>
)
[type] => Array
(
[0] =>
)
[tmp_name] => Array
(
[0] =>
)
[error] => Array
(
[0] => 4
)
[size] => Array
(
[0] => 0
)
)
)
Is there a way where I can avoid this from happening?

Try adding required attribute to input type="file" element to prevent submission of form if no files selected by user
$("form").on("submit", function(e) {
e.preventDefault();
// do `$.ajax()` stuff
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js">
</script>
<form>
<input type="file" name="files[]" multiple required />
<input type="submit" />
</form>

Getting error while using each loop under ajax

When i am trying each loop under Ajax call, i am getting error as:
TypeError: invalid 'in' operand e
Below is my Ajax call code
$.ajax({
type: "POST",
url: "/admin/counselormanagement/centername",
data: 'groupId='+valueSelected,
async: true,
success: function(arrCenter) {
$.each(arrCenter, function( intValue, arrValue ) {
console.log('<option value="' + arrValue['ID'] + '">'+ arrValue['CenterName'] +'</option>');
});
}
});
Response which i am getting back from server is :
Array (
[0] => Array
(
[ID] => 4
[CenterName] => test2
[ParentName] => 2
[Parent] => 3
[GroupName] => test
[Type] => 1
)
[1] => Array
(
[ID] => 8
[CenterName] => test21
[ParentName] => 2
[Parent] => 3
[GroupName] => test
[Type] => 1
)
)
I am using PHP as backend, whose code is :
$arrCenterName = array();
$objCenterMapper = new Application_Model_CentersMapper();
$arrCenter = $objCenterMapper->seekCenters($_POST['groupId']);
print_r($arrCenter[0]);
die();

Use json_encode() in PHP to return response. And your JS code should be like:
PHP:
$arrCenterName = array();
$objCenterMapper = new Application_Model_CentersMapper();
$arrCenter = $objCenterMapper->seekCenters($_POST['groupId']);
echo json_encode($arrCenter[0]);
die();
JQuery:
$.ajax({
type: "POST",
url: "/admin/counselormanagement/centername",
data: 'groupId='+valueSelected,
dataType: 'json',
async: true,
success: function(arrCenter) {
$.each(arrCenter, function( intValue, arrValue ) {
console.log('<option value="' + arrValue.ID + '">'+ arrValue.CenterName +'</option>');
});
}
});

Try to echo out your object using json_encode instead:
<?php
$arrCenterName = array();
$objCenterMapper = new Application_Model_CentersMapper();
$arrCenter = $objCenterMapper->seekCenters($_POST['groupId']);
echo json_encode($arrCenter[0]);
die();

Ajax response array

I want to insert ajax response array into form select input. for the purpose i want to look into array. here is my function;

$failed_classes=$this->db->select('class_student.class_id,course.course_code,course.course_name,course.course_credit')
->join('class','class.class_id=class_student.class_id','LEFT')
->join('course','course.course_id=class.class_course','LEFT')
->where('class.class_status',$active)
->where('class_student.class_marks <=',50)

->order_by('class.class_id')
->get('class_student')->result();
echo $failed_classes;
}

var objectRet= jQuery.parseJSON(response);
for(var i=0;i<objectRet.length;++i) {
alert(objectRet[i].class_id)
}

success: function(response) {
var $select = $('<select id="mySelect"/>');
var $options = response.map(function(a, i) {
return $('<option />', {
value: a.class_id,
text: a.course_code + ' - ' +
a.course_name + ' (' + a.course_credit +')'
});
});
$options.appendTo($select.appendTo($('#someForm')));
}
