I am making an image gallery and am using sql to store the paths. I have changed the names of each file when uploaded, so not to overwrite each other. The file uploads to the directory, but nothing is sent to the database. My row names are pimage and user_id.
<?php
require_once ('includes/config.inc.php');
$page_title = 'YOUR PAGE TITLE GOES HERE';
// Start output buffering:
ob_start();
// Initialize a session:
session_start();
// Check for a $page_title value:
if (!isset($page_title)) {
$page_title = 'User profile Edit';
}
// If no first_name session variable exists, redirect the user:
if (!isset($_SESSION['first_name'])) {
$url = BASE_URL . 'index.php'; // Define the URL.
ob_end_clean(); // Delete the buffer.
header("Location: $url");
exit(); // Quit the script.
}
?>
<?php
session_start();
// Validate log in, etc
$_SESSION['user_id'] = $user_id;
?>
<?php
session_start();
// Validate log in, etc
$_SESSION['user_name'] = $user_name;
?>
<?php
$con = mysql_connect("localhost","xxxxxxxxxxxx","xxxxxxxxxxxx");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("lenmat_registration", $con);
?>
<?php
//define a maxim size for the uploaded images in Kb
define ("MAX_SIZE","100");
//This function reads the extension of the file. It is used to determine if the file is an image by checking the extension.
function getExtension($str) {
$i = strrpos($str,".");
if (!$i) { return ""; }
$l = strlen($str) - $i;
$ext = substr($str,$i+1,$l);
return $ext;
}
//This variable is used as a flag. The value is initialized with 0 (meaning no error found) and it will be changed to 1 if an errro occures. If the error occures the file will not be uploaded.
$errors=0;
//checks if the form has been submitted
if(isset($_POST['Submit']))
{
//reads the name of the file the user submitted for uploading
$image=$_FILES['image']['name'];
//if it is not empty

{
//get the original name of the file from the clients machine
$filename = stripslashes($_FILES['image']['name']);
//get the extension of the file in a lower case format

//we will give an unique name, for example the time in unix time format
$image_name=time(). '.'.$extension;
//the new name will be containing the full path where will be stored (images folder)
$newname="usergallery/".$image_name;
