בעייה בהצבת עוגיות..הדרים נשלחו..

[dor77]

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]

יש לך 2 אנטרים בראש הדף.

[dor77]

מחקתי אותם..עדיין.
אנטר יכול לעשות דבר כזה? חח
בכל אופן לא עזר..אתה רואה משהו אחר אולי?

טנקס (:

[Daniel]

כל טקסט. שלח מחדש את מה שעכשיו כתוב.

באיזה קידוד אתה שומר את זה?

[dor77]

כתוב בדיוק אותה שגיאה.
הקידוד הוא utf-8.

[Daniel]

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]

נסה במקום

echo '<meta http-equiv="refresh" content="10;url=index.php" />';

לכתוב:

header("location: index.php");

רק תזכור להוסיף:

ob_start();

אחרי השורה הראשונה
<?php

[dor77]

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
