Access multiple files from multiple file inputs using $_FILES after using FormData (And add to ACF data on WP Backend)

Using Wordpress, I'm attempting to access files from one out of two file inputs using $_FILES but running into some problems:
To outline - I'm using a front-end form that has two file fields, both of which accept multiple files:
<form id="form" action="" method="post">
<input type="text" name="my_name">
<input type="file" name="reference_images[]" multiple>
<input type="file" name="photo_of_area[]" multiple>
</form>
The file inputs will be taking images, and I need to upload images from "reference_images" to one repeater field, ad "photo_of_area" to another repeater field. This form is posted via AJAX using FormData - the functions for this are below:
function saveForm(varform) {
blockUI();
jQuery.ajax({
type: "POST",
url: window.ajaxObject.ajaxUrl,
dataType: "JSON",
data: varform,
processData: false,
contentType: false,
cache: false,
success: onSuccesPing(),
crossDomain:true,
});
}
jQuery('#form').submit(function(event) {
event.preventDefault(); // Prevent form submitting as normal
var formData = new FormData(jQuery('#form')[0]);
formData.append("action", "messaging_post");
saveForm(formData);
});
I then have a function handle the messaging_post action which is below, this creates a new post with the form data, and loops over the attached images and injects them to my ACF repeater:
add_action( 'wp_ajax_messaging_post', 'messaging_post' );
add_action('wp_ajax_nopriv_messaging_post', 'messaging_post');
function messaging_post(){
if(isset($_POST['my_name'])) {
$name = sanitize_text_field($_POST['my_name']);
$new_post = array(
'ID' => '',
'post_type' => 'quote_requests',
'post_status' => 'publish',
'post_title' => $title,
'post_content' => '',
);
$post_id = wp_insert_post($new_post);
$post = get_post($post_id);
update_field('name', $name, $post_id); // Updates the ACF text field 'name' for the inserted post
// Works, but uploads files from BOTH file inputs to the single ACF repeater:
foreach($_FILES as $value){
for ($i=0; $i <count($value['name']); $i++) {
$errors= array();
$file_name = $value['name'][$i];
$file_size = $value['size'][$i];
$file_tmp = $value['tmp_name'][$i];
$file_type = $value['type'][$i];
$file_ext=strtolower(end(explode('.',$value['name'][$i])));
if(empty($errors)==true) {
$wordpress_upload_dir = wp_upload_dir();
$profilepicture = $wordpress_upload_dir['path'].'/';
move_uploaded_file($file_tmp, $profilepicture.$file_name);
} else{
print_r($errors);
}
$file_name_and_location = $profilepicture.$file_name;
$file_title_for_media_library = $value['name'][$i];
$fildename = $value['name'][$i];
$arr_file_type = wp_check_filetype(basename($fildename));
$uploaded_file_type = $arr_file_type['type'];
$attachment = array(
'post_mime_type' => $uploaded_file_type,
'post_title' => addslashes($file_title_for_media_library),
'post_content' => $fildename,
'post_status' => 'inherit',
'post_parent' => 0,
'post_author' => get_current_user_id(),
);
wp_read_image_metadata( $file_name_and_location );
$attach_id = wp_insert_attachment( $attachment, $file_name_and_location,true,false);
$attach_data = wp_generate_attachment_metadata($attach_id,$file_name_and_location );
wp_update_attachment_metadata( $attach_id, $attach_data );
$images[]= array("image" => $attach_id);
}
}
update_field('photo_area', $images, $post_id);
}
}
The above works, and populates the created post with the name from the form, but this attaches files from BOTH the reference_images and photo_of_area to the photo_area ACF repeater.
When trying to access $_FILES using a function such as the following:
foreach($_FILES["photo_of_area"] as $value){
for ($i=0; $i <count($value['name']); $i++) {
$errors= array();
$file_name = $value['name'][$i];
$file_size = $value['size'][$i];
$file_tmp = $value['tmp_name'][$i];
$file_type = $value['type'][$i];
$file_ext=strtolower(end(explode('.',$value['name'][$i])));
if(empty($errors)==true) {
$wordpress_upload_dir = wp_upload_dir();
$profilepicture = $wordpress_upload_dir['path'].'/';
move_uploaded_file($file_tmp, $profilepicture.$file_name);
} else{
print_r($errors);
}
$file_name_and_location = $profilepicture.$file_name;
$file_title_for_media_library = $value['name'][$i];
$fildename = $value['name'][$i];
$arr_file_type = wp_check_filetype(basename($fildename));
$uploaded_file_type = $arr_file_type['type'];
$attachment = array(
'post_mime_type' => $uploaded_file_type,
'post_title' => addslashes($file_title_for_media_library),
'post_content' => $fildename,
'post_status' => 'inherit',
'post_parent' => 0,
'post_author' => get_current_user_id(),
);
wp_read_image_metadata( $file_name_and_location );
$attach_id = wp_insert_attachment( $attachment, $file_name_and_location,true,false);
$attach_data = wp_generate_attachment_metadata($attach_id,$file_name_and_location );
wp_update_attachment_metadata( $attach_id, $attach_data );
$images[]= array("image" => $attach_id);
}
}
update_field('photo_area', $images, $post);
This doesn't seem to work and returns nothing.
I'm assuming that after going through FormData(), the files are now not accessible on the normal $_FILES['name_of_input'], and should rather have something else done with them?
I've also tried just appending the images to the FormData, but seemed to be having the same issue.
Would anyone be able to shed some light on how I could access $_FILES["photo_of_area"], and also $_FILES["reference_images"] independently of each other after being passed through FormData()? Or any alternative ways that I should look at to achieve the desired behaviour.
Ideally, I need to access images from each file input respectively.
Thanks!

I've managed to achieve this by changing my loop over the $_FILES array as such:
$photo_of_area = $_FILES["photo_of_area"];
foreach ($photo_of_area['name'] as $key => $value) {
$errors = array();
$file_name = $photo_of_area['name'][$key];
$file_size = $photo_of_area['size'][$key];
$file_tmp = $photo_of_area['tmp_name'][$key];
$file_type = $photo_of_area['type'][$key];
$file_ext = strtolower(end(explode('.',$photo_of_area['name'][$key])));
if (empty($errors) == true) {
$wordpress_upload_dir = wp_upload_dir();
$upload_dir_path = $wordpress_upload_dir['path'].'/';
move_uploaded_file($file_tmp, $upload_dir_path.$file_name);
} else {
print_r($errors);
}
$file_name_and_location = $upload_dir_path.$file_name;
$file_title_for_media_library = $photo_of_area['name'][$key];
$fildename = $photo_of_area['name'][$key];
$arr_file_type = wp_check_filetype(basename($fildename));
$uploaded_file_type = $arr_file_type['type'];
$attachment = array(
'post_mime_type' => $uploaded_file_type,
'post_title' => addslashes($file_title_for_media_library),
'post_content' => $fildename,
'post_status' => 'inherit',
'post_parent' => 0,
'post_author' => get_current_user_id(),
);
wp_read_image_metadata( $file_name_and_location );
$attach_id = wp_insert_attachment( $attachment, $file_name_and_location,true,false);
$attach_data = wp_generate_attachment_metadata($attach_id,$file_name_and_location );
wp_update_attachment_metadata( $attach_id, $attach_data );
$area_photos_array[] = array("image" => $attach_id);
}
update_field('photo_area', $area_photos_array, $post_id);
This successfully injects each image uploaded to a new row of the photo_area repeater inside the current post specified by $post_id.

PHP 7 introduced some backward incompatible changes, including the evaluation of indirect expressions. You need to change the line:
$answer = $OOPajax->$_POST['url']($_POST);
to this:
$answer = $OOPajax->{$_POST['url']}($_POST);
to get the old PHP 5 behaviour.
The manual lists other expressions that were affected by this change here: http://php.net/manual/en/migration70.incompatible.php (see the "Changes to variable handling" section).

Ajax filter city and neighbourhood

i´m not getting run my application, i select the city then i need that the dropdown show the NEIGHBORHOODS associated with the city....
this is my getNeighborhoods:
public function pegarBairros ($cidades = null) {
$this->layout = 'json';
$result = array();
debug($_REQUEST['cidade']);
if (in_array($_REQUEST['cidade'], array_keys($this->cidades))) {
$bairros = $this->Cep->find('list', array('fields' => array('id', 'bairro'), 'conditions' => array('uf_sigla' => 'sp', 'cidade' => $this->cidades[$_REQUEST['cidade']]), 'order' => 'bairro', 'group' => 'bairro'));
sort($bairros);
foreach ($bairros as $id => $bairro)
if (!empty($bairro)) $result[$id] = $bairro;
} else $result[] = 'error';
$this->set('data', $result);
}
and this is my ajax:
$('#ImovelCidade').change(function(e) {
$('#ImovelBairro').html($('<option />').val('').text('Carregando...'));
$.getJSON(
"<?php echo Router::url(array('controller' => 'pages', 'action' => 'pegarBairros')) ?>",
{ "cidade" : $(this).val() },
function (data) {
$('#ImovelBairro').html($('<option />').val('').text('Selecione'));
$.each(data, function (chave, valor) {
$('#ImovelBairro').append($('<option />').val(chave).text(valor));
} );
}
);
});
this ajax call the function getNeigh...
this is my select city:
echo $this->Form->input('cidade', array('label' => 'Cidade', 'empty' => 'Selecione uma cidade', 'options' => $Cidades));
my before filter that received city:
public function beforeFilter() {
$this->loadModel('Cidade');
$this->cidade = $this->Cidade->find('list', array ('fields' => array('id','nome')));
$this->set('Cidades',$this->cidade);

How can I call an on page PHP function by pressing a button?

<?php
// Edit this ->
define( 'MQ_SERVER_ADDR', 'XX.XXX.XXX.XXX' );
define( 'MQ_SERVER_PORT', 25565 );
define( 'MQ_TIMEOUT', 1 );
// Edit this <-
// Display everything in browser, because some people can't look in logs for errors
Error_Reporting( E_ALL | E_STRICT );
Ini_Set( 'display_errors', true );
require __DIR__ . '/status/MinecraftQuery.class.php';
$Timer = MicroTime( true );
$Query = new MinecraftQuery( );
try
{
$Query->Connect( MQ_SERVER_ADDR, MQ_SERVER_PORT, MQ_TIMEOUT );
}
catch( MinecraftQueryException $e )
{
$Exception = $e;
}
$Timer = Number_Format( MicroTime( true ) - $Timer, 4, '.', '' );
?>
<link href="css/bootstrap.css" rel="stylesheet" media="screen">
<div class="spanx"><p>
<h1>Login</h1>
Username:<br />
<input type="text" name="username" style="height: 30px; style="width: 220px; value="" />
<br/>
<button>Submit</button>
<?php // Example from PHP.net
$string = '<?php if( ( $Players = $Query->GetPlayers( ) ) !== false ): ?>
<?php foreach( $Players as $Player ): ?>';
if(stristr($string, 'Thisshouldbethestringfromthetextbox') === FALSE) {
echo 'Player is not online';
}
?>
Is my code. Basically what I am trying to do is query my Minecraft server. Check if a player is online by the text form on button click, and if not, deliver a message that says the player is not online, otherwise, keep the person logged in as they browse the site (dunno how to do this either...)
The external query file is:
<?php
class MinecraftQueryException extends Exception
{
// Exception thrown by MinecraftQuery class
}
class MinecraftQuery
{

I would like to solve this in any way that I can. Thanks in advance and ask any questions you need :D.

You can create a form pointing to the same URL to accomplish that.
<form action="<?= $_SERVER['REQUEST_URI'] ?>" method="post">
Username: <input type="text" name="username" />
<button type="submit">Send</button>
</form>
When the form is sent, you can access your input content by accessing $_POST['username']
if (isset($_POST['username'])) {
// your code here
echo 'Username: ' . $_POST['username'];
}
