I've a php code that extract some information from a .dat file uploaded by the user. Now i want to apply this treatment on a set of uploaded file. so the user can choose a set of file when he click upload the treatment has to be done on each file. i've tried this but it's not working : 

     <form method="post" enctype="multipart/form-data">
      <label>Selectionner le fichier .dat</label>
      <input type="file" name="excel" />
      <br />
      <input type="submit" name="import" class="btn btn-info" value="Import" />
     </form>

thank you in advance.

    yes it will naturally won't work, you'll need actual PHP codes, first process the form, usually its under `$_FILES`, since you're expecting multiple files add `[]` in the name attribute. this link can give you an idea https://thedebuggers.com/multiple-files-upload-using-html-php/ – Kevin Sep 12 '18 at 07:14

To let the user select multiple files you have to use the multiple attribute and add brackets [] to the name of the input.

You can do this:

<form method="post" enctype="multipart/form-data">
      <label>Selectionner le fichier .dat</label>
      <input type="file" name="excel[]" multiple />
      <br />
      <input type="submit" name="import" class="btn btn-info" value="Import" />
</form>

Then you can parse the $_FILES array and you will find all the uploaded files, for example:

Array
(
    [excel] => Array
        (
            [name] => Array
                (
                    [0] => img1.PNG
                    [1] => img2.PNG
                    [2] => img3.jpg
                    [3] => img4.png
                )

            [type] => Array
                (
                    [0] => image/png
                    [1] => image/png
                    [2] => image/jpeg
                    [3] => image/png
                )

            [tmp_name] => Array
                (
                    [0] => /tmp/phpWh5NRz
                    [1] => /tmp/php6KEOer
                    [2] => /tmp/phprLvUBi
                    [3] => /tmp/phplTP0Y9
                )

            [error] => Array
                (
                    [0] => 0
                    [1] => 0
                    [2] => 0
                    [3] => 0
                )

            [size] => Array
                (
                    [0] => 63515
                    [1] => 54484
                    [2] => 14001
                    [3] => 84938
                )

        )
