passing variables in forms

Anon

trying to pass varibles in a form so that when an option is selcted from a drop down menu a different action is carried out

<form method="post" action"<?php echo $PHP_SELF?>">
<select name="select">
<option value="<?php echo $all ?>">List all</option>
<option value="<?php echo $type ?>">List sections</option>
</select>
</form>

if ($all) { runn this script
}
elseif ($type) {do this
}

any pointers ?? is it because i am not naming the options ???

becuase if i do -

if ($select) {
}

it works but for any value not for the option selected.

again apologises for coding not at home pc sitting in internet cafe and writing script from memory

thanks

You must name it, and then you could try this if you are trying to make it do a redirect (not sure if that is what you are trying to do): -

<?
if ($target) {
header("Location: $target"); // this must be the first output from the script

}

<head></head><body>
<form method="post" action"<?php echo $PHP_SELF?>">
<select name="select">
<option name="target" value="all.php">List all</option>
<option name="target" value="type.php">List sections</option>
</select>
</form>

my guess is your problem is a result of how multiple options in a select are sent, which is as an array, so you'll need (if i recall correctly) to access them differently.

play around with these:
calling page:
<form action="formtarget.php" method="POST"><p align="center">Show:
<select name="GENDER[]" >
<option value="B" selected>girls and guys</option>
<option value="F">girls only</option>
<option value="M">guys only</option>
</select>
<select name="ORDER[]" class="button">
<option value="RANDOM">random order</option>
<option value="LATEST" selected>latest first</option>
</select>
<input type="submit" value="GO" class="button">
</form>

target PHP page:
while (list($k,$v) = @each($HTTP_POST_VARS)) {

echo "Begin formtarget.php output:<BR><BR>";
echo "k=$k. type=" . gettype ($v);
echo "<BR>v=$v. type=" . gettype ($v);
}

one of the list vars. ($v i think) will say array, and you'll be able to access it like:
$v[1], or somesuch.

search for 'multiple select options on some phorums, and you'll probably get better examples.

Most simply, the values $all or $type are passed to the new page as $select. Replace your if structure with something like this:

if ($select==$all) {
}
elseif ($select==$type) { ... }

Of course you'd have to have $all and $type available on the new page too.

This is what I have been doing...

I use one file but have different forms and each form using $PHP_SELF variable...

<?
if($enter1)
{
do something...
}

if($enter2)
{
do something else...
}
$form1="<form method=post action=$PHP_SELF>
form fields...
<input type=submit value=Submit name=enter1>
</form>";

$form2=<form method=post action=$PHP_SELF>
form fields..
<input type=submit value=Submit name=enter2>
</form>";

echo "$form1<br>";
echo "$form2<br>";
?>

Hope that helps... I may be much more lengthy way to type your code, but it sure makes code a little bit more clear..
