File uploading code not working for .doc file type

Postby iRaajan » Mon Apr 22, 2013 2:05 am

I'm writing PHP code to upload .doc file but it does not giving me desired functionality. I've tested the code for .txt and .pdf file for which it is uploading file but not working with .doc. Here's my code.
BTW, it echos message 'Invalid File'
Code: Select all
<?php
   if(isset($_REQUEST['btn_upload']))
    {
        if ((($_FILES["file"]["type"] == "application/msword")) && ($_FILES["file"]["size"] < 20000))
        {
            if ($_FILES["file"]["error"] > 0)
            {
                echo "Return Code: " . $_FILES["file"]["error"] . "<br />";
            }
            else
            {
                if (file_exists("Documents/" . $_FILES["file"]["name"]))
                {
                    echo $_FILES["file"]["name"] . " already exists. ";
                }
                else
                {
                    move_uploaded_file($_FILES["file"]["tmp_name"],"Documents/" . $_FILES["file"]["name"]);
                    echo "Stored in: " . "Documents/" . $_FILES["file"]["name"];
                }
            }
        }
        else
        {
            echo "Invalid file";
        } 
    }
?>
.../* HTML */
...
<form name="form_add_document" method="post" enctype="multipart/form-data">
<select name="SelectDocFormat">
    <option value="Select Document Format" selected="selected">Select Category</option>
        <option value="TEXT">Text</option>
        <option value="DOC">Word Document</option>
</select>
<input type="file" name="file" value="Browse File">
<input type="submit" name="btn_upload" value="Upload Document">

The $_FILES['file']['type'] is a user supplied value and hence not a good candidate for validation. Use one of the fileinfo() functions, http://www.php.net/manual/en/function.finfo-file.php
