RE: [PHP] Fwd: html form select list selected

2002-03-20 Thread Kevin Stone 

The contents of $display are a string so you must have quotes
aroud it in the comparison statement.

if ($display == 'false') // should work.

Alternatively you could do.

select name=display
option value=0True
option value=1False
/select

Now the contents of $display is an integer which will can be interpreted
as a boolean value (true or false).  Then you can compare it like you
had.

if ($display == false)

Whoops!  Still won't work but that code should read:

echo form;
echo select name=\display\;
echo option value=\true\;
if ($display==true){echo selected;}
echo Display;
echo option value=\false\;
if ($display==false){echo selected;}
echo selectedDon't Display;
echo /select;
echo /form;

I'd like to determine the selected option in a select list based on a
passed variable.  The code below won't work, but I can't figure out why.
 Any guesses?


echo form;
echo select name=\display\;
echo option value=\true\;
if ($display==false){echo selected;}
echo Display;
echo option value=\false\;
if ($display==false){echo selected;}
echo selectedDon't Display;
echo /select;
echo /form;


Thanks!

First of all, this form doesn't have a method or action attribute -- so 
I'm not sure which script you intend to call with it, or what HTTP 
protocol you intend to pass the data with.  But assuming it's the POST 
method and the action is PHP_SELF, and that you are using PHP 4.1.x or 
greater:

// perform a test to see which should be selected
if ($_POST['display'] == 'true') {
   $select_if_true = selected=\yes\;
   $select_if_false = selected=\no\;
} elseif ($_POST['display'] == 'false') {
   $select_if_true = selected=\no\;
   $select_if_false = selected=\yes\;
}

// create the form, including the above-defined variables
$form_html = 
form method=\post\ action=\ . $_SERVER['PHP_SELF'] . \
   select name=\display\
 option $select_if_true value=\true\Display/option
 option $select_if_false value=\false\Don't Display/option
   /select
/form;

// print the form
print $form_html;
