Question

I have a form.

In the form, there is an image upload plus a series of checkboxes.

I am trying to loop through the $_POST vars to process them.

When I do

foreach($_POST as $key => $value){echo "$key $value"; }

I only get ‘input’ $_POST vars outputted. The checkbox values and the image upload value are not.

I am utilizing Code Igniter as a Framework.

Any ideas?
Thanks

You should get any checked checkboxes as part of your $_POST array. Unchecked checkboxes will be absent.

Images uploaded (from <input type="file" /> fields) will be in the $_FILES array, if and only if you set your form enctype to "multipart/form-data" (see here).

To get started handling file uploads in PHP, there’s an excellent tutorial on W3Schools.

Given the HTML:

<input name="foobar" type="file" id="some_id_for_foobar" />

If you want to get the filename of the uploaded file (i.e. the name of the file as it was on the user’s PC), you want:

$name = $_FILES["foobar"]["name"];

If you want the name of the uploaded file on your server, you want:

$location = $_FILES["file"]["tmp_name"];

You may also find the documentation on move_uploaded_file helpful.
