Hi i am trying to make my image upload script insert the file name as well as date_added, user_id and id into my database upon upload into the file directory.

At the moment it uploads and stores it into a file directory but i can't get it to insert into the database.

The table name is ptb_photos and the columns are id, user_id (id = user_id), file_name and date_added.

Here's my code, can someone let me know where i'm going wrong. I'm new to php and still learning so apologies if it's completely wrong.

<?php
session_start()
?>
<?
$sql=mysql_query("INSERT INTO ptb_photos SET file_name ='".addslashes($filename)."' WHERE id=".$_SESSION['user_id']." AND user_id=".$_SESSION['user_id'].""); 

// LOG
$log = '=== ' . @date('Y-m-d H:i:s') . ' ===============================' . "\n"
        . 'FILES:' . print_r($_FILES, 1) . "\n"
        . 'POST:' . print_r($_POST, 1) . "\n";
$fp = fopen('upload-log.txt', 'a');
fwrite($fp, $log);
fclose($fp);


// Result object
$r = new stdClass();
// Result content type
header('content-type: application/json');


// Maximum file size
$maxsize = 10; //Mb
// File size control
if ($_FILES['xfile']['size'] > ($maxsize * 1048576)) {
    $r->error = "Max file size: $maxsize Kb";
}


// Uploading folder
$folder = 'files/';
if (!is_dir($folder))
    mkdir($folder);

// If specifics folder 
$folder .= $_POST['folder'] ? $_POST['folder'] . '/' : '';
if (!is_dir($folder))
    mkdir($folder);

// PASS USER_ID HERE
$folder2 = '../'. '../'. 'data/'. 'photos/'. $_SESSION['user_id'] . '/';
if (!is_dir($folder2))
    mkdir($folder2);

// New directory with 'files/USER_SESSION_ID/'
$folder = $newDir . $folder2;


// If the file is an image
if (preg_match('/image/i', $_FILES['xfile']['type'])) {

    $filename = $_POST['value'] ? $_POST['value'] :
            $folder . 'pic1.jpg';
} else {

    $tld = split(',', $_FILES['xfile']['name']);
    $tld = $tld[count($tld) - 1];
    $filename = $_POST['value'] ? $_POST['value'] :
            $folder . sha1(@microtime() . '-' . $_FILES['xfile']['name']) . $tld;
}


// Supporting image file types
$types = Array('image/png', 'image/gif', 'image/jpeg');
// File type control
if (in_array($_FILES['xfile']['type'], $types)) {
    // Create an unique file name    
    // Uploaded file source
    $source = file_get_contents($_FILES["xfile"]["tmp_name"]);
    // Image resize
    imageresize($source, $filename, $_POST['width'], $_POST['height'], $_POST['crop'], $_POST['quality']);
} else
// If the file is not an image
if (in_array($_FILES['xfile']['type'], $types)) 
    move_uploaded_file($_FILES["xfile"]["tmp_name"], $filename);



// File path
$path = str_replace('upload_image_1.php', '', $_SERVER['SCRIPT_NAME']);

// Result data
$r->filename = $filename;
$r->path = $path;
$r->img = '<img src="' . $path . $filename . '" alt="image" />';

// Return to JSON
echo json_encode($r);

尝试这个：

$sql = mysql_query('INSERT INTO ptb_photos (file_name, id, user_id) 
values  ("$filename","$_SESSION[user_id]", "$_SESSION[user_id]"');

顺便说一句，INSERT INTO 语法永远不能有 WHERE 子句，除非你使用：

INSERT INTO ... SELECT * FROM ... WHERE
