file upload issue in php
<p>Ok I am to the point of pulling my hair out. I have been trying all day to get this to work right and nothing. Right now what this script is doing is when you go to upload the file it goes to the page and there is no image. I have no clue why aint it working right. I am still new at this file/image upload thing. I have tried a few different ways and nothing. Here is the upload.php code:</p>

<pre><code>      &lt;?php
    function dbConnect(){
    // Connect to the database
    $hostname="localhost";
     $database="myDatabase";
     $mysql_login="myLogin";
     $mysql_password="myPassword";

     if(!($db=mysql_connect($hostname, $mysql_login, $mysql_password))){
        echo"error on connect";
     }
     else{
        if(!(mysql_select_db($database,$db))){
            echo mysql_error();
            echo "&lt;br /&gt;error on database connection. Check your settings.";
        }
        else{
                    echo "This is the home page. I have successfully made a connection to my database and everything
     is working as it should.";
            }
   }
    $aryImages=array("image/jpeg","image/png");
    $aryDocs=array("application/msword","application/pdf","video/x-msvideo");
    $filename=filenameSafe($_FILES['upload']['name']);
    $fileType=$_FILES["upload"]["type"];
    if (in_array($_FILES["upload"]["type"],$aryImages)){
        createThumb($fileType,$_FILES['upload']['tmp_name'],$filename,100,100);
    }
    elseif (in_array($_FILES["upload"]["type"],$aryDocs)){
        move_uploaded_file($_FILES['upload']['tmp_name'],
    "/home/valerie2/public_html/elinkswap/imagefolder/".$filename);
        $aryColumns=array("sessionID"=&gt;$curSess,"fileName"=&gt;$filename,"fileType"=&gt;$fileType,"thumbFileName"=&gt;$thumbFilename,"dateCreated"=&gt;date('Y-m-d H:i:s'));
        dbInsert($filename,$aryColumns,$_FILES["upload"]["type"]);
    }
    else{

        echo "File Uploaded";
      }
     }
    function createThumb($type,$tmpname,$filename,$new_w,$new_h){
        $thumbFilename="tmb-".$filename;

        }
        $old_x=imageSX($src_img);
        $old_y=imageSY($src_img);

<p>And this is my index.php code:</p>

<pre><code>&lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"&gt;
&lt;html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"&gt;
&lt;head&gt;
    &lt;title&gt;File Upload&lt;/title&gt;
&lt;link href="styles.css" type="text/css" rel="stylesheet" /&gt;
&lt;/head&gt;
&lt;body&gt;


&lt;form enctype="multipart/form-data" action="upload.php" method="post"&gt;

Select File: &lt;input type="file" name="upload"&gt;
&lt;input type="hidden" name="MAX_FILE_SIZE" value="1000000"/&gt;
&lt;input name="Submit" type="submit" value="Upload File"&gt;

&lt;/form&gt;
&lt;/html&gt;
</code></pre>

<p>Both these files are inside a folder name imagefolder only with a folder called upload. I have read so many things on the file/image and so many videos but I still aint understand why the picture wont show up.I even tried to do another way but it kept telling me invaild file type.</p>
