PHP „implodieren“ Fehler bei der Einreichung Form

Question

Nur bemerkte ich diese Fehler erhalten, wenn ich nicht eine Checkbox auswählen und einreichen:

Warning: implode() [function.implode]: Invalid arguments passed in /home/content/o/l/t/oltvcb/html/feedback_mtg.php on line 148

Warning: Cannot modify header information - headers already sent by (output started at /home/content/o/l/t/oltvcb/html/feedback_mtg.php:148) in /home/content/o/l/t/oltvcb/html/feedback_mtg.php on line 162

Ich habe bemerkt, dass die Formulardaten tatsächlich kam per E-Mail durch ...

etwas mit dem „Optionen“ Feld

Unten ist die Form zu tun Code:

#<?php 
// ------------- CONFIGURABLE SECTION ------------------------ 

// $mailto - set to the email address you want the form 
// sent to, eg 
//$mailto  = "youremailaddress@example.com" ; 

$mailto = 'xxxxx@xxxxxxxxx.com' ; 

// $subject - set to the Subject line of the email, eg 
//$subject = "Feedback Form" ; 

$subject = "Request For Visitor Guide" ; 

// the pages to be displayed, eg

Answer 1

Abgesehen von der Tatsache, dass einige ernsthaft scheußlichen Code, Ihre Fehler ersetzen Sie diese Zeile zu beheben:

$options = $_POST['options'] ; 

mit diesem:

$options = array(); 
if(isset($_POST['options'])) { 
    $options = $_POST['options']; 
} 

Der Fehler ist im Grunde, wenn Sie wählen keine Option $options ist nicht als ein Array festgelegt, so, wenn Sie versuchen, implode darauf zu tun PHP ist unglücklich, weil es ein Array erwartet.

Answer 2

if (isset($_POST['options']) 
{ 
    implode(...) 
} 

Ich gehe mit diesem .... dieses kapselt alles in einer Funktion.
