בעייה בהצבת עוגיות..הדרים נשלחו..
 
שלום.
בניתי טופס התחברות.
הרעיון הוא כזה:

אם הכפתור נלחץ - המערכת תבדוק אם הפרטים נכונים, אם כן תחבר את המשתמש, אם לא (else) מציג לו את הטופס עם שגיאה.
אם הכפתור לא נשלח - מציג לו את הטופס בלבד.

כשאני מצליח להתחבר..אני מקבל שגיאה:
Cannot modify header information - headers already sent by
אני מקבל פעמיים, השורות שמצויינות הן השורות של הצבת העוגיות.


זה הקוד המלא:

לא כתבתי שום דבר לפני כן, הדף ריק לגמרי..מה נחשב "header"? אולי הלולאה שם?

תודה רבה לכם :)

Daniel 01-03-10 21:42
יש לך 2 אנטרים בראש הדף.

dor77 01-03-10 21:51
מחקתי אותם..עדיין.
אנטר יכול לעשות דבר כזה? חח
בכל אופן לא עזר..אתה רואה משהו אחר אולי?

טנקס (:

Daniel 01-03-10 22:27
כל טקסט. שלח מחדש את מה שעכשיו כתוב.

באיזה קידוד אתה שומר את זה?

dor77 01-03-10 22:43
כתוב בדיוק אותה שגיאה.
הקידוד הוא utf-8.

Daniel 01-03-10 22:46
1. את הקוד. שלח את הקוד בדיוק כמו שמופיע לך בקובץ.
2. שמור כ-UTF WITHOUT BOM.

בול מה שיש בקובץ.

בקשר לקידוד, איך שומרים קידוד כזה?

yNaxon 01-03-10 23:46
נסה במקום
קוד:
echo '<meta http-equiv="refresh" content="10;url=index.php" />';
לכתוב:
קוד:
header("location: index.php");
רק תזכור להוסיף:

קוד:
ob_start();
אחרי השורה הראשונה
<?php

dor77 02-03-10 01:50
לא..
עכשיו יש שלשושה הודעות כאלה:

Warning: Cannot modify header information - headers already sent by (output started at c:\wamp\www\a\sign_in.php:1) in c:\wamp\www\a\sign_in.php on line 17

Warning: Cannot modify header information - headers already sent by (output started at c:\wamp\www\a\sign_in.php:1) in c:\wamp\www\a\sign_in.php on line 18
