Turning an array into a select field

[funkafaction]

Quick question, can you tell me how to turn an array into a select field?

 

Thanks.

Show me how the array is formatted.

[funkafaction]

$timezone_array = array( );

 

$timezone_array = array(

"GMT -12:00" => "International Date Line West";

);

How do you want the select option formatted? Do you want the key of the array to be the value of the select and the value of the array to be the "text" of the option?

[funkafaction]

Yes.

[DarkWater]

foreach ($timezone_array as $k=>$v) {

      printf('<option value="%s">%s</option>', $k, $v);

}

[funkafaction]

It's not quite working, %s is showing up. I have no idea what I'm doing when it comes to PHP, so do you mind explaining it to me?

 

Thanks.

It is taking the array that you had loaded with data, and then foreach , $k which refers to the key which would be GMT -12:00 set its value to $v which would be "International Date Line West". Then go through till the end of the array. Printf is the same as echo but allows formatting. so the %s refers to a string. And then what ever order you put the variables in is the places they will be placed and then echoed. So $k (which is the key) is set to the value, and the value of key ($v)  is set to be showed.

 

full code would be

<?
$timezone_array = array(
               "GMT -12:00" => "International Date Line West"
            );

foreach ($timezone_array as $k=>$v) {
       printf('<option value="%s">%s</option>', $k, $v);
}
?>
