עזרה בהעלאת קובץ לשרת
אהלן,
לא כותב פה הרבה, אבל נתקלתי בבעיה בהעלאת קובץ לשרת, ואני די אובד עצות...
אחרי שהרצתי את הסקריפט של העלאת התמונה קיבלתי את הודעת השגיאה הבאה:

Warning: unlink(): Unable to access in /home/degem/domains/degem.net/public_html/testing/maad/upload.php on line 161

<title>web.blazonry : PHP : Upload and Resize an Image</title>

/*== upload directory where the file will be stored
relative to where script is run ==*/
$imgfile = $HTTP_POST_FILES['imgfile']['tmp_name'];
$uploaddir = "tmp";
/*== get file extension (fn at bottom of script) ==*/
/*== checks to see if image file, if not do not allow upload ==*/
$pext = getFileExtension($imgfile_name);
$pext = strtolower($pext);
if (($pext != "jpg") && ($pext != "jpeg"))
{
print "<h1>ERROR</h1>Image Extension Unknown.<br>";
print "<p>Please upload only a JPEG image with the extension .jpg or .jpeg ONLY<br><br>";
print "The file you uploaded had the following extension: $pext</p>\n";
/*== delete uploaded file ==*/
unlink($imgfile);
exit();

//-- RE-SIZING UPLOADED IMAGE

file name. This is done so if multiple people access the

$tmpimg = tempnam("/tmp", "MKUP");

אני צריך לציין שאני לא ספץ ב-PHP, והסקריפט הוא משהו מוכן. (ניסיתי להוסיף לו דברים, כשלא עבד הרצתי את הבסיס והתקבלה אותה שגיאה)
בכלל, עושה רושם שהמחשב לא שולח את הקבצים, אין זמן המתנה שהקבצים יעלו.
מי שיכול לעזור, יבורך 
תודה מראש... |
