I have a small script to upload a previously chosen number of photos from 1-10 - but once I want to add the files (upload, resize and write database entries), I get this very very long site full of errors.
I'm a PHP newbie, and I don't really know how to use the foreach and arrays and that stuff in this case.
I've looked at the database after trying to post photos - it created a new row for each file I tried to upload, but it didn't enter any data, is just wrote the word "Array" into each fields (except the ID). So I assume that the information in the arrays is not correctly passed on... ?!?
this is my code:
<?php
include('config.php');
echo $header;
if ($_POST['action'] == "add") {
foreach ($_POST['title'] as $title) {
//__ upload & resize _______________________________________
$ul_photo = $_FILES['photo']['tmp_name'];
$src = imagecreatefromjpeg($ul_photo);
list($width,$height) = getimagesize($ul_photo);
$newwidth = 550;
$newheight = ($height/$width)*$newwidth;
$tmp = imagecreatetruecolor($newwidth,$newheight);
imagecopyresampled($tmp,$src,0,0,0,0,$newwidth,$newheight,$width,$height);
$filename = $dirpath.$gal_id."/". $_FILES['photo']['name'];
imagejpeg($tmp,$filename,100);
#__ thumb _________________________________________________________
$ul_thumb = $_FILES['photo']['tmp_name'];
$srcthumb = imagecreatefromjpeg($ul_thumb);
list($widththumb,$heightthumb) = getimagesize($ul_thumb);
$newwidththumb = 100;
$newheightthumb = ($heightthumb/$widththumb)*$newwidththumb;
$src_top = ($src_height / 2) - ($dst_height / 2);
$src_left = ($src_width / 2) - ($dst_width / 2);
$tmpthumb = imagecreatetruecolor($newwidththumb,$newheightthumb);
imagecopyresampled($tmpthumb,$srcthumb,0,0,$src_top,$src_left,$newwidththumb,$newheightthumb,$widththumb,$heightthumb);
$thumbname = $dirpath.$gal_id."/zth_".$_FILES['photo']['name'];
imagejpeg($tmpthumb,$thumbname,100);
#___________________________________________________________________
imagedestroy($src);
imagedestroy($tmp);
imagedestroy($srcthumb);
imagedestroy($tmpthumb);
$gal = addslashes($_POST['gal_id']);
$photo = $_FILES['photo']['name'];
$title = addslashes($_POST['title']);
$description = addslashes($_POST['description']);
$sql = "INSERT INTO $gal_photos (gal,photo,title,description) VALUES ('$gal','$photo','$title','$description')";
$query = mysql_query($sql) or die("MySQL Error: <br /> {$sql} <br />". mysql_error());
$num = mysql_affected_rows();
if($num > 0) {
echo "<span class='result'>New Photo successfully added!</span>";
echo "<br /><img src='../galleries/".$gal."/zth_".$photo."' />";
} else {
echo "Error: ".mysql_error();
}
