Nu har jag grubblat i sömnen halva natten om ett annat problem som uppstod när jag lyckats repetera i sidled.
För mig funkar ALLT i scripten jag gjort. jag kan ladda upp bilder och skriva bildtext osv. Men så fort frugan skall prova på sin dator här redvid mig så laddar den bara upp en bild men skapar ingen thumb och stannar då...
Nedan följer all kod om någon har lust att se över det.
Upload.php - skippade alla con string ovan för body osv...
Kod:
<body bgcolor="#CCCCCC">
<?php
//define a maxim size for the uploaded images
define ("MAX_SIZE","9999999");
// define the width and height for the thumbnail
// note that theese dimmensions are considered the maximum dimmension and are not fixed,
// because we have to keep the image ratio intact or it will be deformed
define ("WIDTH","120");
define ("HEIGHT","100");
*// this is the function that will create the thumbnail image from the uploaded image
// the resize will be done considering the width and height defined, but without deforming the image
function make_thumb($img_name,$filename,$new_w,$new_h)
{
*//get image extension.
*$ext=getExtension($img_name);
*//creates the new image using the appropriate function from gd library

*$old_x=imageSX($src_img);
*$old_y=imageSY($src_img);
* // next we will calculate the new dimmensions for the thumbnail image
*// the next steps will be taken:
*// *1. calculate the ratio by dividing the old dimmensions with the new ones
*// 2. if the ratio for the width is higher, the width will remain the one define in WIDTH variable
*// *and the height will be calculated so the image ratio will not change
*// 3. otherwise we will use the height ratio for the image
*// as a result, only one of the dimmensions will be from the fixed ones
*$ratio1=$old_x/$new_w;

Har funderat på om jag kan göra Upload.php och bildtext.php i samma fil... Jobbigt å klicka sig rung hela tiden.
ser ni några feting fel så säg till!
EDIT: idag kan jag inte ladda upp bilder över huvud taget :(
EDIT2: verkar som om att den inte tål att jag laddar upp bilder större än 1mb... Men i scripten verkar ju inte någon max gräns finnas angett ? |
