ik heb een vraag over een upload form
ik heb meerdere scripts geprobeerd maar krijg het niet voor elkaar dus begin te twijfelen of ik niet een instelling verkeerd heb staan ofzo, het lijkt me onmogelijk dat alle geprobeerde scripts niet werken.
nu gebruik ik deze:
<?php
ini_set('display_errors', 1);
error_reporting(E_ALL);
if(isset($_POST))
{
//Some Settings
$ThumbSquareSize = 200; //Thumbnail will be 200x200
$BigImageMaxSize = 500; //Image Maximum height or width
$ThumbPrefix = "thumb_"; //Normal thumb Prefix
$DestinationDirectory = 'images/'; //Upload Directory ends with / (slash)
$Quality = 90;
// check $_FILES['ImageFile'] array is not empty
// "is_uploaded_file" Tells whether the file was uploaded via HTTP POST
if(!isset($_FILES['ImageFile']) || !is_uploaded_file($_FILES['ImageFile']['tmp_name']))
{
die('Something went wrong with Upload!'); // output error when above checks fail.
}
// Random number for both file, will be added after image name
$RandomNumber = rand(0, 9999999999);
// Elements (values) of $_FILES['ImageFile'] array
//let's access these values by using their index position
$ImageName = str_replace(' ','-',strtolower($_FILES['ImageFile']['name']));
$ImageSize = $_FILES['ImageFile']['size']; // Obtain original image size
$TempSrc = $_FILES['ImageFile']['tmp_name']; // Tmp name of image file stored in PHP tmp folder
$ImageType = $_FILES['ImageFile']['type']; //Obtain file type, returns "image/png", image/jpeg, text/plain etc.
//Let's use $ImageType variable to check wheather uploaded file is supported.
//We use PHP SWITCH statement to check valid image format, PHP SWITCH is similar to IF/ELSE statements
//suitable if we want to compare the a variable with many different values
switch(strtolower($ImageType))
{
case 'image/png':
$CreatedImage = imagecreatefrompng($_FILES['ImageFile']['tmp_name']);
break;
case 'image/gif':
$CreatedImage = imagecreatefromgif($_FILES['ImageFile']['tmp_name']);
break;
case 'image/jpeg':
case 'image/pjpeg':
$CreatedImage = imagecreatefromjpeg($_FILES['ImageFile']['tmp_name']);
break;
default:
die('Unsupported File!'); //output error and exit
}
//PHP getimagesize() function returns height-width from image file stored in PHP tmp folder.
//Let's get first two values from image, width and height. list assign values to $CurWidth,$CurHeight
list($CurWidth,$CurHeight)=getimagesize($TempSrc);
//Get file extension from Image name, this will be re-added after random name
$ImageExt = substr($ImageName, strrpos($ImageName, '.'));
$ImageExt = str_replace('.','',$ImageExt);
//remove extension from filename
$ImageName = preg_replace("/\\.[^.\\s]{3,4}$/", "", $ImageName);
//Construct a new image name (with random number added) for our new image.
$NewImageName = $ImageName.'-'.$RandomNumber.'.'.$ImageExt;
//set the Destination Image
$thumb_DestRandImageName = $DestinationDirectory.$ThumbPrefix.$NewImageName; //Thumb name
$DestRandImageName = $DestinationDirectory.$NewImageName; //Name for Big Image
//Resize image to our Specified Size by calling resizeImage function.
if(resizeImage($CurWidth,$CurHeight,$BigImageMaxSize,$DestRandImageName,$CreatedImage,$Quality,$ImageType))
{
//Create a square Thumbnail right after, this time we are using cropImage() function
if(!cropImage($CurWidth,$CurHeight,$ThumbSquareSize,$thumb_DestRandImageName,$CreatedImage,$Quality,$ImageType))
{
echo 'Error Creating thumbnail';
}
/*
At this point we have succesfully resized and created thumbnail image
We can render image to user's browser or store information in the database
For demo, we are going to output results on browser.
echo '<table width="100%" border="0" cellpadding="4" cellspacing="0">';
echo '<tr>';
echo '<td align="center"><img src="uploads/'.$ThumbPrefix.$NewImageName.'" alt="Thumbnail"></td>';
echo '</tr><tr>';
echo '<td align="center"><img src="uploads/'.$NewImageName.'" alt="Resized Image"></td>';

// Insert info into database table!
include ("connect.php");
mysql_query("INSERT INTO events (ImageName, ThumbName, ImgPath)
VALUES ($DestRandImageName, $thumb_DestRandImageName, 'images/')");
}else{
die('Resize Error'); //output error
}
}
// This function will proportionally resize image
function resizeImage($CurWidth,$CurHeight,$MaxSize,$DestFolder,$SrcImage,$Quality,$ImageType)

}
}
?>ik heb in de folder waar ook index.php staat (voor het testen niet in de root) een map images gemaakt en deze op 777 gezet
als ik het uitvoer krijg ik deze fout:
Warning: imagejpeg(): Unable to open '/images/7thsunday-8046636637.jpg' for writing: No such file or directory in /var/www/vhosts/8/136894/webspace/httpdocs/website.nl/test/processupload.php on line 130 Warning: imagejpeg(): Unable to open '/images/thumb_7thsunday-8046636637.jpg' for writing: No such file or directory in /var/www/vhosts/8/136894/webspace/httpdocs/website.nl/test/processupload.php on line 177
kan iemand mij vertellen waarom dit niet werkt?
tnks!
