when i specify the second image as the dafault, it works. but it's getting the only the default not the uploaded when someone uploads a file. so basically, i have two problems here:
the uploaded image is not being passed/uploaded properly
the default image is not being get from the server properly
please help me. i dont know what to do. i have read posts, almost the same but it didn't help me. thanks a lot in advance!

Answer 1

Try to do the major two change in your code :
Replace code if(isset($_FILES['file']['tmp_name'])){
With if($_FILES['file']['tmp_name']!=""){
Remove path from default image : $uploadFilename = 'def_img.jpg';
I have tried its working fine. The complete code by which i have test that default image and uploaded image both available for further processing.
$directory_self = str_replace(basename($_SERVER['PHP_SELF']), '', $_SERVER['PHP_SELF']);
// make a note of the directory that will recieve the uploaded files //i made it as the same directory where the .php file is
$uploadsDirectory = $_SERVER['DOCUMENT_ROOT'] . $directory_self;
#echo "$uploadsDirectory<br>";
#exit;
$fieldname = 'file';
if(isset($_POST['submit']))
{
if($_FILES['file']['tmp_name']!="")
{
$allowedExts = array("jpeg", "jpg");
$temp = explode(".", $_FILES['file']['name']);
$extension = end($temp);
$notallowedExts = array("png", "gif", "pdf", "doc", "docx", "txt", "html", "xlsx", "mov");
$nottemp = explode(".", $_FILES['file']['name']);
$notextension = end($nottemp);
if ((($_FILES['file']['type'] == "image/jpeg") || ($_FILES['file']['type'] == "image/jpg")) && ($_FILES['file']['size'] < 1300000) && in_array($extension, $allowedExts))
{
$now = time();
while(file_exists($uploadFilename = $uploadsDirectory.$now.'-'.$_FILES[$fieldname]['name']))
{
$now++;
}
move_uploaded_file($_FILES[$fieldname]['tmp_name'], $uploadFilename);
}
elseif(($_FILES['file']['size'] > 1300000)||(in_array($notextension, $notallowedExts)))
{
echo '<script type="text/javascript">';
echo 'alert("Invalid file upload. Please check your input.");';
echo 'window.location.href = "index.php";';
echo '</script>';
die();
}
}
