Got an empty $_POST array with a form

Question

I've got a problem with an empty $_POST array while i'm uploading a file.

Here's the form :

<div class="popup">
    <h3>UPLOAD</h3>
        <a class="close" href="#">&times;</a>
        <div class="content">
            <form
                id="uploadForm"
                method="post" 
                enctype="multipart/form-data" 
                action="resources/upload.php?dir=<?php if(isset($_GET['dir'])){echo $_GET['dir'];} ?>" 
                enctype="multipart/form-data">

                <input type="file" name="fichier" id="file" class="inputfile"/>
                <label for="file">Choisir un fichier</label><br>
            </form>
            <button onClick="submitUpload();" id="smbtBtt">Uploader</button>
        </div>
</div>

This is the submitUpload fonction :

function submitUpload()
{
    if(document.getElementById("file").value != ""){
        document.getElementById("uploadForm").submit();
    }
    else
    {
        alert("Please select a file!");
    }

}

Then in the upload.php file, i just var_dump() the array $_FILES and $_POST

It's 6AM in the morning, my 5h straight of programming, so that's why i'm asking :).

Thanks a lot !

you have use var formData= new formdata(); function to get all file data.. — Gulshan S

You are using file type field elements in your form. So you need to use $_FILES instead of $_POST — Ganesh Radhakrishnan

Here in your form, you are using file type field element. You have to use '$_FILES' instead of $_POST. Try this

Sorry guys, I wasn't able to make the $FILES and the $POST arrays work at the same time, so I find an other solution without one of them. Still tanks to every one.

what solution you found.There must be some error in your code because of which you are not able to use POST and FILE at the same time

Death-is-the-real-truth Over a year ago

in your current code you don't have anything else apart from file and that's why $_POST is empty

@Anant That's ok, I've resolved it. Now i got some ACL errors ... T_T

use this code. May be it helps you

$('form#uploadForm').submit(function(e){
    var formData = new FormData(this);

$.ajax({
url: "upload_file.php",            
type: "POST",
data:  formData,
mimeType:"multipart/form-data",
contentType: false,
cache: false,
processData:false,
success: function(data)
{
    alert(data);
}
});
return false;
});

I need to user the POST methode. You can't transfer files with the GET one. And It's my POST array in php that is empty..

Bilal Ahmed Over a year ago
