Upload image and all types of files with javascript program

Look at the file before uploading.

 Preview file type jpg / png.

 here we will use two methods to upload files 

upload image 

upload all type 

using two push doors

controllers         

    base

        javacript.php

---

Sample: 

    <!-- Avatar Upload Preview -->

<script type="text/javascript"> $(function(){ $("#uploadFile").on("change", function(){ var files = !!this.files ? this.files : []; if (!files.length || !window.FileReader) return; // no file selected, or no FileReader support if (/^image/.test( files[0].type)){ // only image file var reader = new FileReader(); // instance of the FileReader reader.readAsDataURL(files[0]); // read the local file reader.onloadend = function(){ // set image data as background of div $("#uploadImagePreview").css("display","block"); $("#imagePreview").css("background-image", "url("+this.result+")"); $("#imagePreview").css("max-height","223px"); $("#imagePreview").css("height","223px"); } } }); }); </script>

To preview the file we need the help of smart people by building it 

    <!-- Image Upload Preview -->

    <!---script src="assets/js/base/jquery-1.8.0.min.js"--!></script---!>

download and wrap the file with a text editor jquery.min.js

github_jquery-1.8.0.min.js

---

assets

      js

           base

                     jquery.min.js

---

or prefer to take away from cloud storage

Microsoft CDN :

<!--script src = "Http://ajax.aspnetcdn.com/ajax

/jQuery/jquery-1.8.0.js"--!>
</script--!>

Google CDN :

    <!--script src = "Http://ajax.googleapis.com/ajax

/libs/jquery/1.8.0/jquery.min.js"--!>
</script--!> 

Make sure they are really installed,

Are files and folders created?

If it is already

let's create a push door for each file

shortpreview avatar

<div class="col-md-6">

                        <div class="shortpreview">

                            <label for="">Previous Avatar </label>

                            <br> 

                            <img src="userfiles/avatars/you_avatar" class="img-responsive">

                        </div>

                    </div>

code Uploads php avatar

 $Destinasti = '../userfiles/avatars'; //capture the file image toss and save it in a folder

if(!isset($_FILES['ImageFile']) || !is_uploaded_file($_FILES['ImageFile']['tmp_name'])){ $NewImageName= 'default.png';            move_uploaded_file($_FILES['ImageFile']['tmp_name'], "$Destination/$NewImageName");        }        else{            $RandomNum   = rand(0, 9999999999);            $ImageName = str_replace(' ','-',strtolower($_FILES['ImageFile']['name']));            $ImageType = $_FILES['ImageFile']['type'];            $ImageExt = substr($ImageName, strrpos($ImageName, '.'));            $ImageExt = str_replace('.','',$ImageExt);            $ImageName = preg_replace("/\.[^.\s]{3,4}$/", "", $ImageName);            $NewImageName = $ImageName.'-'.$RandomNum.'.'.$ImageExt;            move_uploaded_file($_FILES['ImageFile']['tmp_name'], "$Destination/$NewImageName");       

Upload All file

$Destination = '../userfiles/background-images'; if(!isset( $_FILES ['BackgroundImageFile']) || !is_uploaded_file( $_FILES ['BackgroundImageFile']['tmp_name'])) { $BackgroundNewImageName= 'default-background.jpg'; move_uploaded_file( $_FILES['BackgroundImageFile']['tmp_name'], "$Destination/ $BackgroundNewImageName"); } else{ $RandomNum = rand(0, 9999999999); $ImageName = str_replace(' ','-',strtolower( $_FILES ['BackgroundImageFile']['name'])); $ImageType = $_FILES['BackgroundImageFile']['type']; $ImageExt = substr($ImageName, strrpos($ImageName, '.')); $ImageExt = str_replace('.','',$ImageExt); $ImageName = preg_replace("/\.[^.\s]{3,4}$/", "", $ImageName); $BackgroundNewImageName = $ImageName.'-'.$RandomNum.'.'.$ImageExt; move_uploaded_file($_FILES ['BackgroundImageFile']['tmp_name'], "$Destination/ $BackgroundNewImageName"); }
