Hi!

I got this script for upload images and working fine. Got images width always 700px * 460px or 700px * 1050px. But for new project I need always same height, not weight. Anybody have some idea what to change in my code?

 

<?php
require_once('zastita.php');
//Start session
session_start();

//Podaci za spajanje na bazu podataka
require_once('config.php');

//Array za provjeru jesu li ispunjena sva polja
$errmsg_arr = array();

//Isključivanje provjere jesu li ispunjena sva polja
$errflag = false;

//Spajanje na mysql server
$link = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD);
if(!$link) {
	die('Greška prilikom spajanja na server: ' . mysql_error());
}

//Odabir baze podataka
$db = mysql_select_db(DB_DATABASE);
if(!$db) {
	die("Greška prilikom spajanja na bazu podataka");
}
?>
<?php include ("include/head.php"); ?>

simple math - you just need to specify the width instead of the height. Swap your newwidth and newheight variables. Carefully adjusting the calculation to use the other variable.

 

<?php
$newheight=700;
$newwidth=($height/$width)*$newheight;
$tmp=imagecreatetruecolor($newwidth,$newheight);
?>

edit - make sure to switch the order -- put the "newheight" variable above the "newwidth" variable.
