Upload image to folder using ajax / jquery
I'm trying to upload an image to a folder using ajax, jquery and php, but the problem is I don't know how to send the file input value to the php file when I run my code. I receive the following message:
undefined index archivo
This is my ajax call (PD. All other parameters are working correctly, I only have problems with the input file value)
function Registrar() {
var cat = $('#cat').val();
var nom = $('#name').val();
var desc = $('#description').val();
var image = $('#archivo').val();
//Also tried with this, to remove the fakepath string... $('input[type=file]').val().replace(/C:\\fakepath\\/i, '')
$.ajax({
url: '../../class/upload.php',
method: 'POST',
data: { categoria: cat, nombre: nom, descripcion: desc, archivo: image, activo: act, disponible: disp, precio: prec },
success: function (data) {
console.log(data);
}
});
}
PHP file:
<?php
$categoria = $_POST['categoria'];
$nombre = $_POST['nombre'];
$descripcion = $_POST['descripcion'];
$img = $_POST['archivo'];
$activo = $_POST['activo'];
$disponible = $_POST['disponible'];
$precio = $_POST['precio'];
$IdCategoria = 0;
$filepath = "";
//Imagen
if($categoria=="Piano") {
$IdCategoria = 1;
$filepath = "../Files/Productos/Piano/".$img;
}
$filetmp = $_FILES['archivo']['tmp_name'];
move_uploaded_file($filetmp, $filepath);
echo $IdCategoria.$nombre.$descripcion.$filepath.$activo.$disponible.$categoria.$precio;
?>
And the important parts of my HTML:
<form id="registerForm" method="post" role="form" enctype="multipart/form-data" >
<input name="archivo" id="archivo" style="width: 70%;" name="textinput" class="btn btn-block" type="file" onchange="showimagepreview(this)" />
EDIT: showimagepreview
function showimagepreview(input) {
if (input.files && input.files[0]) {
var reader = new FileReader();
reader.onload = function (e) {
document.getElementsByTagName("img")[0].setAttribute("src", e.target.result);
}
reader.readAsDataURL(input.files[0]);
}
}
How can I solve this?

Here's the solution
Html
<form id="registerForm" method="post" enctype="multipart/form-data">
<input name="archivo" id="archivo" style="width: 70%;" class="btn btn-block" type="file" onchange="PreviewImage(this)" />
<img id="uploadPreview" />
<button type="submit">Submit</button>
Java Script
function PreviewImage() {
var oFReader = new FileReader();
oFReader.readAsDataURL(document.getElementById("image").files[0]);
oFReader.onload = function (oFREvent) {
document.getElementById("uploadPreview").src = oFREvent.target.result;
};
};
//ajax
$("#registerForm").submit(function(event) {
var formData = new FormData($(this)[0]);
if ($(this).valid()) {
$.ajax({
url : '../../class/upload.php',
type : 'POST',
data : formData,
contentType : false,
cache : false,
processData : false,
success: function(e) {alert(e) },
error : function(x, t, m) {},
});
}
});
PHP
<?php
echo "<pre>"; print_r($_FILES);echo "</pre>"; die; //this will show you the file transfered by form.
$categoria = $_POST['categoria'];
$nombre = $_POST['nombre'];
$descripcion = $_POST['descripcion'];
$img = $_POST['archivo'];
$activo = $_FILES['activo'];
$disponible = $_POST['disponible'];
$precio = $_POST['precio'];
$IdCategoria = 0;
$filepath = "";
//Imagen
if($categoria=="Piano") {
$IdCategoria = 1;
$filepath = "../Files/Productos/Piano/".$img;
}
$filetmp = $_FILES['archivo']['tmp_name'];
move_uploaded_file($filetmp, $filepath);
echo $IdCategoria.$nombre.$descripcion.$filepath.$activo.$disponible.$categoria.$precio;
?>

Submit your form data like this:
var formData = new FormData($("form")[0]);
$.ajax({
url: '../../class/upload.php',
method: 'POST',
data: formData,
success: function (data) {
console.log(data);
}
});
And you should get the file from $_FILES
, you cannot get it in $_POST
in php code.
