I've no clue if this is possible, I was just wondering to myself.

Is it possible to make a form input have more than one value? Like putting an array or something.
Like say I wanted one select input have the values 'blue', 'solid', and '1'. Can I make it into an array somehow, and then retrieve each value with PHP?

i'm not so sure on your question, but if you got predefined values then sure, it'd be pretty easy, hers a little somethin somethin...

<?
if( isset($_POST['submit']) )
{
	// splits the value up
	$array = explode("|", $_POST['select1']);

	$color = $array[0];
	$type = $array[1];
	$width = $array[2];

	echo $color . $type . $width ."<br />\n";
}
else
{
	echo "<form action=\"". $_SERVER['PHP_SELF'] ."\" method=\"post\">\n";
	echo "	<select name=\"select1\">\n";
	echo "		<option value=\"blue|solid|1\">Blue / Solid / 1</option\n";
	echo "	</select>\n";
	ehco "</form>\n";
}

i haven't tested it, but it should work, basically you define the value and use the explode() function to seperate the value!

Ah! I see. Now it makes sense, thanks.
I never thought of using explode(), lol, I'm too used to list(). Plus I was thinking something about multi-dimensional arrays and making something stupid like 'value="something[]"', but that's for adding multiple values from different inputs into one value, but that wouldn't be what I wanted.
I don't have an immediate use for this, it was just something that passed my mind as I was doing something else.

Your code looks logical enough that it should work, so thanks.

Oh, and you missed a greater-than sign in your closing options tag, and you have some un-needed space in your form tag's method attribute, by the way.

Coolaid, this may be irrelevant but why did you use | as a seperator? Or is it jsut a matter of preference?

[Matthew.]

Its completly a matter of preference, many people use the pipe symobol ( | ) as its not commonly used.

Lang: As Matt just said, however make sure you don't use a separator that could be used in the data input

If you want a select box that can select multiple values, and you want to get all the values used, you have to make the name an array.
i.e.

<select name="something[]">
<!-- options -->
</select>

<?
if($_POST['something'])
	highlight_string(print_r($_POST['something'],1));
?>
