Step 1: Create Index.php file and implement below html code :
<h2>Select Image</h2> <input class="form-control" type="file" name="file" id="file" /> <br /> <span id="uploaded_image"></span>
Step 2: Implement below jquery to upload image:
<script>
$(document).ready(function(){
$(document).on('change', '#file', function(){
var name = document.getElementById("file").files[0].name;
var form_data = new FormData();
var ext = name.split('.').pop().toLowerCase();
if(jQuery.inArray(ext, ['gif','png','jpg','jpeg']) == -1)
{
alert("Invalid Image File");
}
var oFReader = new FileReader();
oFReader.readAsDataURL(document.getElementById("file").files[0]);
var f = document.getElementById("file").files[0];
var fsize = f.size||f.fileSize;
if(fsize > 2000000)
{
alert("Image File Size is very big");
}
else
{
form_data.append("file", document.getElementById('file').files[0]);
$.ajax({
url:"upload.php",
method:"POST",
data: form_data,
contentType: false,
cache: false,
processData: false,
beforeSend:function(){
$('#uploaded_image').html("<label class='text-success'>Image Uploading...</label>");
},
success:function(data)
{
$('#uploaded_image').html(data);
}
});
}
});
});
</script>
Step 3: Create upload.php file and Implement php script to save posted image into folder:
<?php
//upload.php
if($_FILES["file"]["name"] != '')
{
$test = explode('.', $_FILES["file"]["name"]);
$ext = end($test);
$name = rand(100, 999) . '.' . $ext;
$location = '../image/' . $name;
move_uploaded_file($_FILES["file"]["tmp_name"], $location);
echo '<img src="'.$location.'" height="250" width="425" class="img-thumbnail" />';
}
?>
