Codeigniter can't get file input value

[c_pattle]

I have a form with a file input field to allow users to upload image files. 

 

<input id="petPhoto" type="file" value="photo" name="petPhoto">

 

The problem I'm having is that I can't get the value in this field when the form is submitted (e.g images/fileimage.jpg). 

 

In my controller I have the following line to try to get the value but when I do a var dump on it, it just returns false. 

 

$petPhoto = $this->input->post('petPhoto');

 

Does anyone know what I'm doing wrong?

Why not just use the CI Uploader class?

try this:

 

$petPhoto = $_FILES['petPhoto']['name'];

Use what 'deals' said. Just because you're using a framework, doesn't always mean you need to use all the functions built into it. Sometimes using the core PHP functions can be much easier than the frameworks built in functions.

 

What is wrong with your code is that you're trying to access the $_POST array, when really you need to be accessing the $_FILES array. Read through the related section on the official CodeIgniter user guide here.

 

EDIT: As of yet, I have not found a way of accessing the $_FILES array through the CodeIgniter functions/classes, however I will look more into that as I am unsure if that is correct or not.

 

EDIT ^x2: Also make sure your form tag includes the enctype attribute, it should look something like this:

enctype="multipart/form-data"

first you need to know you are using the input type file , so be sure to  use the enctype , second use $_FILES or the uploader class of Codeigniter.

Your problem is over.
