Php Multiple File Upload Codeigniter
Carmel Kittell
I am trying to get a multiple upload library working for my Codeigniter based website. I have it working almost but I have a slight problem if I upload more than one image, the file extentions get screwed up; for example, if I upload three JPEGS, I get this in my uploads folder,
I was able to get multiple file uploads to work with clux's method but I had to modify the upload class slightly (I'm using Codeigniter 2). First I created a duplicate of the CI upload class into my applications library.
I modified Cubed Eye's MY_upload to return the file information of all files uploaded. As it was, only the last file's information was accessible when calling the data method. I also added the IP address of the uploader to that list.
You should see an upload form. Try uploading an image file (either ajpg, gif, png, or webp). If the path in your controller is correct it shouldwork.
When you upload files they can be accessed natively in PHP through the $_FILES superglobal. This array has somemajor shortcomings when working with multiple files uploaded at once, and has potential security flaws many developersare not aware of. CodeIgniter helps with both of these situations by standardizing your usage of files behind acommon interface.
Files are accessed through the current IncomingRequest instance. To retrieve all files that were uploaded with thisrequest, use getFiles(). This will return an array of files represented by instances of CodeIgniter\HTTP\Files\UploadedFile:
Of course, there are multiple ways to name the file input, and anything but the simplest can create strange results.The array returns in a manner that you would expect. With the simplest usage, a single file might be submitted like:
The UploadedFile instance corresponds to $_FILES. Even if a user just clicks the submit button and does not upload any file, the instance will still exist. You can check that the file was actually uploaded by the isValid() method in UploadedFile. See Verify a File.
As seen in this example, if a file had an upload error, you can retrieve the error code (an integer) and the errormessage with the getError() and getErrorString() methods. The following errors can be discovered throughthis method:
In this tutorial, i will share with you how to upload multiple image in codeigniter 3 application. we can easily do multiple file upload example in codeigniter.i will give you simple example with step by step to upload multiple file in codeigniter 3 application. we will use upload library for multiple file upload in codeigniter. using upload library we will store all images or files store in our uploads directory.So, let's follow few bellow step to upload multiple file or images example:Step 1: Download Fresh Codeigniter 3In First step we will download fresh version of Codeigniter 3, so if you haven't download yet then download from here : Download Codeigniter 3.Step 2: Add RouteIn this step you have to add some route in your route file. So first we will create route for image uploading example.so put the bellow content in route file:application/config/routes.phpStep 4: Create ViewIn this step we will create imageUploadForm.php view file . In this file we will write design of html form using form helper and url helper. So let's update following file:application/views/imageUploadForm.php Codeigniter - Upload Multiple Files and Images Example - ItSolutionStuff.com
Ok Now we are ready to run Above example, But We have to create "uploads" folder on your root directory before run example. all images will upload on "uploads" directory so make sure permission too.So let's run bellow command on your root directory for quick run:php -S localhost:8000Now you can open bellow URL on your browser: :8000/image-uploadMake Sure, First you have to set base URL on your bellow configuration file :application/config/config.phpRead Also: Codeigniter Curl Post Request with Parameters Example$config['base_url'] = ' :8000/';I hope it can help you...Download Source Code form here: Download From GithubTags :

In this section, we will learn how to upload more than one image and file by using Codeigniter. The following example provides a simple way to upload more than one image and file. In order to upload multiple files, we will use the upload library in Codeigniter. This library uses an uploads directory to save all the files and images. The steps to upload more than one image and files are described as follows:
In the second step, we are going to Add Route. We will use our route file to add route. In our below example of image uploading, we will create route. For this, we will use a route file and add the following content in that file.
In the third step, we are going to Create Controller. For this, we will create an "ImageUpload" controller. After that, we will create two functions index() and uploadImage(). We will use the application/controllers/Items.php path so that we can create the Items.php file. After creating this file, we will add the following code into it:
Now our above code is ready to run. In order to run this code, we need to create a "Upload" folder. We will create it in our root directory. The "upload" directory will get all the uploaded images. That's why we should also require permission.
File upload is the most used feature in the web application where the files are managed dynamically. The file can be easily uploaded to the server using PHP. Also, you can upload multiple files at a time using PHP. For the CodeIgniter web application, you can use the system library to implement file upload functionality. CodeIgniter Upload library helps you to upload files to the server in CodeIgniter.
By default, it is assumed that you only intend to use CodeIgniter tomanage one application, which you will build in your appdirectory. It is possible, however, to have multiple sets ofapplications that share a single CodeIgniter installation, or even torename or relocate your application directory.
This would have two apps, foo and bar, both having standard application directoriesand a public folder, and sharing a common codeigniter4/framework.
Today I will teach you to make a multiple file upload in CodeIgniter 4. Uploading files are common on most of the online platforms today, like uploading photos on social media, uploading videos in a video sharing platform or uploading resume in a job searching site.
Above file, index method is just for showing the upload form, and there is nothing much happening in this method. The doupload method is responsible for the server side script to upload a real file and save in the server. We will write the contents of this file after we discuss the upload form in detail.
You can see the index() method just called the upload form to display the multiple upload form.
The next method doupload() is the main method that upload the files to server via Ajax. At first line, it check is there any files existing, if so it uploads the file in the next line. I have used codeigniter $request library to fulfill the file upload. You can use whatever php way that you familiar with.

We should inherit and hack Codeigniter file upload library to give it the ability to upload multiple files with single input, although we can do this task without any other library but for code clean and to avoid repetitions I recommended to use this library
This library doesn't change anything to write your code, so if you have already build your project with regular codeigniter file upload library you will not have to change the original uploading code, this library will detect single or multi upload, your turn to handle inserting files information to your table;
This light Wight jQuery Plugin helps you to easily select multiple files for upload. It lets you do some basic validations before files uploaded, based on their extension or size, I use it to make simple Codeigniter upload file example without any complex features
Uploading files asynchronously can be a pain at the best of times, but when coupled with CodeIgniter, it can be a particularly frustrating experience. Gladly, there is now a very easy way to upload multiple files using jQuery Form Plugin.
This tutorial discusses the process of creating a CodeIgniter based file upload component that could be easily used to upload images and other files with ease. You could validate and even restrict file size and type during the upload process.
The next step is the creation of a file in the controller folder. Name the file upload_controller.php. In this file, I will load a library for initializing the Upload class through the following code:
you could see this function in action when you call the file_view.php file. if you are at a staging domain, use the URL: your-domain/ci_demo/index.php/upload_controller/file_view OR in the case of loclhost: localhost/ci_demo/index.php/upload_controller/file_view
