hallo,
ik heb een upload script van het internet geplukt.
en ik wou vragen hoe of ik hier meerder files in kan laten uploaden:
functie.php
<?php
// Image converter & uploader
function insertImage($upload, $dir, $q, $width, $height) {
/* Insert array image system
Format for array : ResizeWidth, ResizeHeight, ResizeQuality, FolderLocation
Example 1 : $image_set[] = array ('320', '240', '95', 'upload/images/resize/');
Example 1 : $image_set[] = array ('240', '180', '90', 'upload/images/thumb/');
Special format : Use 'set' for no resize. (normal upload)
Example : $image_set[] = array ('set', 'set', 'set', 'upload/images/');
NOTE : Quality settings are 1-100. FolderLocation should end with a slash '/'.
*/
// Fill this array with thumbnail settings
$image_set = array ();
@mkdir("images/".$_POST["naam"]."",0777) or die("
Er bestaan al een directory met die titel, dus tevens ook een nieuws bericht met die titel!<br>
<a href=\"javascript:history.back(-1)\">Keer terug</a>, en verzin een andere titel");
@mkdir("images/".$_POST["naam"]."/ori",0777);
@mkdir("images/".$_POST["naam"]."/thumb",0777);
$setdir = $dir;
$image_set[] = array ('set', 'set', 'set', 'images/'.$setdir.'/ori/');
