How to send data from PHP to HTML

Is there any way to send data from php to html without refreshing page.
i open html to upload images..
so i will go to process.php and i got target-path of that images when it has success uploaded.
my problem is. how can i send that target-path to my html back without refreshing page.
This is my javascript:
function startUpload(){
..
return true;
}
function stopUpload(success){
var result = '';
if (success == 1){
.. //get data from php
} else {
..
}
return true;
}
process.php
$destination_path = "../dir/";
$result = 0;
$target_path = $destination_path . basename( $_FILES['myfile']['name']);
if(#move_uploaded_file($_FILES['myfile']['tmp_name'], $target_path)) {
$result = 1;
//$target-path need to send to input in html
}
sleep(1);

My suggestion would be ajax. It's cleaner and efficient.
Example is how you parse the data
This is for HTML to PHP
$('#submit').click(function()
{
$.ajax({
url: send_email.php,
type:'POST',
data:
{
email: email_address,
message: message
},
success: function(msg)
{
alert('Email Sent');
}
});
});
If you want to pass a value from PHP to HTML
An example would be :
<?php
if( isset($_GET['submit']) )
{
//be sure to validate and clean your variables
$val1 = htmlentities($_GET['val1']);
$val2 = htmlentities($_GET['val2']);
//then you can use them in a PHP function.
$result = myFunction($val1, $val2);
}
?>
<?php if( isset($result) ) echo $result; //print the result above the form ?>
<form action="" method="get">
Inserisci number1:
<input type="text" name="val1" id="val1"></input>
<?php echo "ciaoooo"; ?>
<br></br>
Inserisci number2:
<input type="text" name="val2" id="val2"></input>
<br></br>
<input type="submit" name="submit" value="send"></input>
</form>
In your case it would be :
$destination_path = "../dir/";
$result = 0;
$target_path = $destination_path . basename( $_FILES['myfile']['name']);
if(#move_uploaded_file($_FILES['myfile']['tmp_name'], $target_path)) {
$result = 1;
$val1 = htmlentities($_GET['val1']); // this value could be obtain via HTML
}
sleep(1);

If your Javascript will handle upload event through AJAX. you can return back correct image url and append back to your webpage.
Try this before add jquery to your html page:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
Html Form:
<span id="returnImage"></span>
<form id="uploadImage">
<label id="img">Upload Image<label>
<input name="images" type="file" class="img"/>
<input type="submit"/>
</form>
JS:
$("#uploadImage").submit(function(e){
e.preventDefault();
var data = new FormData();
$.each($('.img'), function(i, obj) {
$.each(obj.files,function(j, file){
data.append('upload_files['+i+']', file);
});
});
$.ajax({
type: 'post',
data: data,
url: "image_processor.php",
cache: false,
contentType: false,
processData: false,
success: function(data){
var dataArray = $.parseJSON(data);
$("#returnImage").html('<img src="'+dataArray["img"]+'"/>')
});
});
});
image_processor.php
<?php
$array_add_counter = 0;
foreach ($_FILES['upload_files']['name'] as $imageNameArray){
$NewImage[$array_add_counter]['name'] = $imageNameArray;
$array_add_counter++;
}
$array_add_counter = 0;
foreach ($_FILES['upload_files']['type'] as $imageTypeArray){
$NewImage[$array_add_counter]['type'] = $imageTypeArray;
$array_add_counter++;
}
$array_add_counter = 0;
foreach ($_FILES['upload_files']['tmp_name'] as $imageTmpArray){
$NewImage[$array_add_counter]['tmp_name'] = $imageTmpArray;
$array_add_counter++;
}
$array_add_counter = 0;
foreach ($_FILES['upload_files']['error'] as $imageErrorArray){
$NewImage[$array_add_counter]['error'] = $imageErrorArray;
$array_add_counter++;
}
$array_add_counter = 0;
foreach ($_FILES['upload_files']['size'] as $imageSizeArray){
$NewImage[$array_add_counter]['size'] = $imageSizeArray;
$array_add_counter++;
}
foreach ($NewImage as $images) {
move_uploaded_file($images["tmp_name"], "ImageLocation/".$images["name"]);
$return['img'] = "ImageLocation/".$images["name"];
}
echo json_encode($return);
?>
I tested and it work in my localhost.

How to upload multiple image with Ajax?

I have a website using the Kohana framework. I have a problem when I tried upload multiple image using AJAX. I tried with many methods but without success. I think the problem is in function _save_images($image) at line:
if ($file = Upload::save($image, NULL, $directory))
Because I tried echo this values but receive result like:
Website not support width less than 900px on Computer
A function to save image with parameter $image is array list image.
In ProductImage.php:
protected function _save_images($image)
{
$directory = DOCROOT.'uploads/';
if ($file = Upload::save($image, NULL, $directory))
{
$filename = strtolower(Text::random('alnum', 20)).'.jpg';
Image::factory($file)
->resize(200, 200, Image::AUTO)
->save($directory.$filename);
// Delete the temporary file
unlink($file);
return $filename;
}
}
And I have a function to upload multiple image.
public function action_create()
{
$user = Auth_Jelly::instance()->get_user();
$iduser = $user->id;
if($user->has_role('admin') || $user->check_permission($iduser,'CREATE_PRODUCT')==1){
$this->auto_render = false;
if(Request::$is_ajax)
{
$name_img = Security::xss_clean($_POST['name_img']);
$type_img = Security::xss_clean($_POST['type_img']);
$size_img = Security::xss_clean($_POST['size_img']);
$new_array = array();
foreach($name_img as $item){
$new_array['name'][] = $item;
}
foreach($type_img as $item){
$new_array['type'][] = $item;
}
foreach($size_img as $item){
$new_array['size'][] = $item;
}
$files = $new_array;
unset($new_array);
$ilosc = count($files['name'])-1;
for($i=0; $i<=$ilosc; $i++) {
$_FILES['image_list'.$i]['name'] = $files['name'][$i];
$_FILES['image_list'.$i]['type'] = $files['type'][$i];
$_FILES['image_list'.$i]['size'] = $files['size'][$i];
$array_new[] = array(
'name'=>$_FILES['image_list'.$i]['name'],
'type'=>$_FILES['image_list'.$i]['type'],
'error'=>0,
'size'=>$_FILES['image_list'.$i]['size'],
);
}
foreach ($array_new as $key => $value) {
$this->_save_images($value);
if($this->save_images($value)==FALSE){
echo "Faild Upload";
}else{
echo "Upload Success";
}
}
}
}else{
// Request::current()->redirect('admin/home/denied');
}
}
And in ProductImage.js:
$("#"+form).click(function(){
var image_list = Array();
var imageFiles = document.getElementById("image_list"),
filesLength = imageFiles.files.length;
for (var i = 0; i < filesLength; i++) {
image_list[i] = imageFiles.files[i].name;
}
var myFileList = document.getElementById('image_list').files;
var file ;
var name_img= Array();
var type_img= Array();
var size_img= Array();
// loop through files
for (var i = 0; i < myFileList.length; i++) {
// get item
file = myFileList.item(i);
//or
file = myFileList[i];
name_img[i]= file.name;
type_img[i]= file.type;
size_img[i]= file.size;
}
var local = window.location;
var val_content = tinyMCE.editors[0].getContent();
var language = $.trim($('#product-create-language option:selected').val());
var category = $.trim($('input[name=category]').val());
var status = $.trim($('input[name=createstatus]:checked').val());
var position = $.trim($('input[name=createposition]:checked').val());
var matches = [];
$(".addcheck:checked").each(function() {
matches.push(this.value);
});
if(matches.length>0)
matches=matches;
else
matches=null;
if(validateSpace(title,"<img src='"+base_url+"themes/admin/images/false.png' alt='false'>",titleinfo) && validateSpace(image,"<img src='"+base_url+"themes/admin/images/false.png' alt='false'>",imageinfo) && validateSpace(imagebig,"<img src='"+base_url+"themes/admin/images/false.png' alt='false'>",imagebiginfo) && validateSpace(imagemobile,"<img src='"+base_url+"themes/admin/images/false.png' alt='false'>",imagemobileinfo) && validateSpace(keywords,"<img src='"+base_url+"themes/admin/images/false.png' alt='false'>",keywordsinfo) && validateSpace(description,"<img src='"+base_url+"themes/admin/images/false.png' alt='false'>",descriptioninfo) && validateSpace(date,"<img src='"+base_url+"themes/admin/images/false.png' alt='false'>",dateinfo)){

type: "POST",
data: data,
cache: false,
success: function(html) {
console.log(html);
}
});
}else{
return false;
}
});
});
That seem many code, so, I hope anyone can be help me.

Source : How to upload multiple files using PHP, jQuery and AJAX

In your code error looks like near,
foreach ($array_new as $key => $value) {
$this->_save_images($value);
if($this->save_images($value)==FALSE){
echo "Faild Upload";
}else{
echo "Upload Success";
}
}
when you call $this->_save_images($value); you don't save file name for uploaded image. $file_name = $this->_save_images($value); and than save this $file_name,
foreach ($array_new as $key => $value) {
$file_name= $this->_save_images($value);
if($this->save_images($file_name)==FALSE){
echo "Faild Upload";
}else{
echo "Upload Success";
}
}

HTML form must be have the “method” attribute with the “post” value. Because the file will only send to the server when the value of the method attribute of the form is post.
<form method="post" name="multiple_upload_form" id="multiple_upload_form" enctype="multipart/form-data" action="upload.php">
<input type="hidden" name="image_form_submit" value="1"/>
<label>Choose Image</label>
<input type="file" name="images[]" id="images" multiple >
<div class="uploading none">
<label> </label>
<img src="uploading.gif"/>
</div>
</form>

CONTROLLER
public function upload_files(){
$order_id = 123;
if(!$order_id){
redirect('home/instant_quote', 'refresh');
}else{
$this->load->library('upload');
//$files = $this->input->post();
$files = $_FILES;
if($files){
for( $i = 1; $i < 20; $i++) {
$config = array();
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'jpg|jpeg|png|pdf|dwg|zip';

$inserted['name'] = $image_data["upload_data"]["file_name"];
$inserted['extension'] = $image_data["upload_data"]["file_ext"];
$inserted['type'] = $image_data["upload_data"]["file_type"];
$inserted['size'] = $image_data["upload_data"]["file_size"];
$prop = $this->home->insert_files($inserted);
}
}
}else{
$this->load->view('comman/header.php');
$this->load->view('home/add_files.php');
$this->load->view('comman/footer.php');
}
}
}
This is what i see when i log the form data

You can use this in your controller:
function upload(){
if(!empty($_FILES)){
$type= $_FILES["files0"]["type"]; //files0 is your input file name
$size= $_FILES["files0"]["size"];
$file_name = $_FILES["files0"]["name"];
$source = $_FILES['files0']['tmp_name'];
$dir = "./uploads/";
$file = $dir . $file_name;
if(!file_exists ($file ))
{
move_uploaded_file($source,$file );
exit("File has been uploaded");
}
else
{
echo "File exist";
}
}
$this->load->view('v_test');
}
And for your ajax jquery:
//add this to your head html
<script>
var base_url = "<?php echo base_url(); ?>";
</script>
and, this is your ajax call :
$("#submit_files").click(function() {
var formData = new FormData($("#form_files")[0]);
$.ajax({
url: base_url + "home/upload_files",
type: 'POST',
data: formData,
async: false,
success: function (data) {
alert(data)
},
cache: false,
contentType: false,
processData: false
});
return false;
});
Please test with single file first, and if it worked. Try to dynamically upload multiple files. Hope this help you out. :D

When I upload image and text by separate form, its work well. But Its not work when I add together.
My form text upload by js and image upload by a php file.
And I think my problem in my form.
If I upload together with js, What change in my js and submit.php, which also add below.

}
}
}
?>

on click of submit you can put the code in js you have to make change in the js file
$.post('phpapgename.php',data:jquerydata,function(){
})
in the .php page you can put your query to submit your data.

You cannot have nested form. Try to avoid it and separate out the forms as below. And while submitting any form if you data from other form, create a hidden fields in this form and submit it.
Another suggestion: Since you're working with javascript anyway, outsource the upload-form to an invisible div and make it pop up by clicking/hovering an upload-button or entering the last field of form1 or whatever.

CodeIgniter File upload does not understands ajax file submission

I have written a JS script, a CodeIgniter controller and a html form to upload the files via jquery ajax.
It does not uploads files. I have solved all the issues but this last one was beyond my ability.
The AJAX request completes successfully but the codeigniter upload class erros "you did not select a file to upload."
Here is my HTML file and button:
<input type="file" class="form-file" id="file" multiple name="file[]" />
<input value='add picture' type="button" name="file-submit" class="form-submit" id='file-submit'/>
And here is the CodeIgniter controller responsible to upload the files:
class Upload extends CI_Controller
{
function pictures ()
{
$config['upload_path'] = '../uploads/categories/';
$this->load->library("upload", $config);
if(!$this->upload->do_upload("file"))
{
echo $this->upload->display_errors();
}
else
{
echo "Thanks";
}
}
}
And here is the jQuery AJAX script:
$(document).ready(function()
