Re: passing array as hidden field

Concept is solid, method is wrong. Understand that <name=layer[]> is but one index in the array. To produce an array with multiple indicies you must create a separate <input> for each value. Example.. foreach ($layer as $lay) { echo "<input type='hidden' name='layer[]' value=$lay>"; } That will produce.. <input type='hidden' name='layer[]' value=a> <input type='hidden' name='layer[]' value=b> <input type='hidden' name='layer[]' value=c> And when the submit button is pressed $_POST will contain the list array $layer. -Kevin ----- Original Message ----- From: "Pushkar Pradhan" <pushkar@ERC.MsState.Edu> To: <php-general@lists.php.net> Sent: Wednesday, April 24, 2002 12:02 PM Subject: [PHP] passing array as hidden field > I want to pass a 1 dim. array through a form, I use the hidden field and > do as follows: > <form method=POST ACTION=\"updateHTML.php\"> > <input type=hidden name=layer[] value=\""; > foreach($layer as $lay) { > print "$lay "; > } > print "\"> > This generates the foll. source: > <form method=POST ACTION="updateHTML.php"> > <input type=hidden name=layer[] value="a b c d e f g h "> > > where actually it should be $layer[] = "a", "b", "c", .... > i.e. it doesn't remain an array anymore and thus I cannot do array > operations (eg. array_slice etc.) on it. > Can anyone tell how I can pass it to my forms as an array?
