Can I get some help with an upload form?
I'm new to writing php and learning as I go. I grabbed this from another post here (thank you to whomever wrote it! I can't recall right now). I'm trying to edit it to meet my needs. I need a form to allow my customers to upload images. I then need to be able to retrieve the images and match them up with the customer's order number. I figure if I can store the image name in the db along with the customer order number and information, I can then call it back right? I have the form writing everything except the image name to the db.
The images are stored in a file called 'pictures'. After I get some assistance getting the image name written to the db, I need some help writing the code that I can use to view the images. It doesn't need to be pretty, I just need to see what images go with which order. Each order will likely have multiple images so calling them up by order number would be great.
Here's what I have for my upload.php
Am I correct in that this is the part I need to edit in order to write the image name to the db? I'm thinking it's $file_name part, though I could be totally wrong.PHP Code:<?php
//connect to mysql. You MUST edit these! (except localhost)
mysql_connect("localhost", "***", "**") or die(mysql_error());
mysql_select_db("***") or die(mysql_error());
//upload directory.
//change to fit your need eg. files, upload .... etc.
$upload_dir = "pictures/";
//number of files to upload.
$num_files = 3;
//the file size in bytes.
$size_bytes =2048000; //51200 bytes = 50KB.
//Extensions you want files uploaded limited to.
$limitedext = array(".gif",".jpg",".jpeg",".png");
//check if the directory exists or not.
if (!is_dir("$upload_dir")) {
die ("Error: The directory <b>($upload_dir)</b> doesn't exist");
}
//check if the directory is writable.
if (!is_writeable("$upload_dir")){
die ("Error: The directory <b>($upload_dir)</b> is NOT writable, Please CHMOD (777)");
}
//if the form has been submitted, then do the upload process
//infact, if you clicked on (Upload Now!) button.
if (isset($_POST['upload_form'])){
echo "<h3>Upload results:</h3>";
//do a loop for uploading files based on ($num_files) number of files.
for ($i = 1; $i <= $num_files; $i++) {
//define variables to hold the values.
mysql_query("INSERT INTO files (description, order_number, email, name) VALUES('$description', '$order_number', '$email', '$name') ") or die(mysql_error());
$new_file = $_FILES['file'.$i];
$description = $_POST['description'];
$order_number = $_POST['order_number'];
$email = $_POST['email'];
$name = $_POST['name'];
$file_name = $new_file['name'];
//to remove spaces from file name we have to replace it with "_".
$file_name = str_replace(' ', '_', $file_name);
$file_tmp = $new_file['tmp_name'];
$file_size = $new_file['size'];
#-----------------------------------------------------------#

echo "File $i: ($file_name) already exists.<br>";
}else{
#-----------------------------------------------------------#
# this function will upload the files. :) ;) cool #
#-----------------------------------------------------------#
if (move_uploaded_file($file_tmp,$upload_dir.$file_name)) {
echo "File $i: ($file_name) Uploaded.<br>";
}else{
echo "File $i: Faild to upload.<br>";

}#end of (file_exists).
}#end of (file_size).
}#end of (limitedext).
