Question

I can’t seem to get files to be uploaded with PHP. From what I can tell, everything checks out. I even went as far as digging up the old textbook and copied the example straight out of the text and still no go.

At first, I was thinking it was an issue with the directory permissions where the files are being saved so I changed permissions to 777 and still nothing. If anyone has any suggestions I’m all ears :/

Here is the code (HTML):

  <form action="upload.php" method="post" enctype="multipart/form-data">
    <input type="file" name="file1">
        <br/>
    <input type="submit" value="Upload">
  </form>

The PHP file:

<?php
$tmp_name = $_FILES['file1']['tmp_name'];
$path = getcwd() . DIRECTORY_SEPARATOR . 'images';
$name = $path . DIRECTORY_SEPARATOR . $_FILES['file1']['name'];
$success = move_uploaded_file($tmp_name, $name);
if($success) {
    $upload_message = $name . ' has been uploaded.';
    echo "$upload_message";
} else {
    echo "something went wrong :(";
}
?>

You should be checking for an upload error before attempting to move it then you can track down the problem:
http://www.php.net/manual/en/features.file-upload.errors.php

Heres a basic example:

<?php
error_reporting(-1);

$uploaddir = './images/';

// Check for upload attempt
if(isset($_FILES['file1'])){
    $uploadfile = $uploaddir.basename($_FILES['file1']['name']);

    // If no error
    if($_FILES['file1']['error'] == 0){
        //Attempt to move
        if (move_uploaded_file($_FILES['file1']['tmp_name'], $uploadfile)) {
            echo "File is valid, and was successfully uploaded.";
        }else{
            echo 'Error moving file.';
        }
    } else {
        // Has error
        $errors = array(0=>'OK',
                        1=>'UPLOAD_ERR_INI_SIZE',
                        2=>'UPLOAD_ERR_FORM_SIZE',
                        3=>'UPLOAD_ERR_PARTIAL',
                        6=>'UPLOAD_ERR_NO_TMP_DIR',
                        7=>'UPLOAD_ERR_CANT_WRITE',
                        8=>'UPLOAD_ERR_EXTENSION'
                        );
        echo "Error: ".$errors[$_FILES['file1']['error']];
    }
}

BTW. Be very wary of allowing uploads.
