[RESOLVED] Dynamic Post Variables.

Nyxll

I have a cycle of pregenerated buttons generated by a loop.
I need to access a certain "set" of them based on the feedback from a radio button.

I am trying to use dynamic variables to create such logic.

I have a radio box called 'Char' that is an integer. This tells me which character to affect.

Below I am just trying to get the character's name from the posted variables.

if ($x==$POST['Char'])
{
$tmpVar = "POST['CharName" . $x . "']" ;
echo $tmpVar; // displays "_POST['CharName1" whch is good.
$test= ${$tmpVar};
echo $test; //This just fails and for some reason
//my error reporting will not help me out.
}

I found a little snippet that helped me in the right direction, but it is not quite there.
$user="bob";
$holder="user";
echo "${$holder}";

Any help would be fabulous.

What exactly do u want to do?

From what I can see all you've done is initialised a new variable, made $test the same as the new variable but you haven't assigned a value to it which is why you don't get anything printed out.

e.g. if $x = 1 you get

$test = $_POST['CharName1'];

but you haven't assigned any value to $_POST['CharName1']

the $_POST['CharName1'] is assigned by the form below that is submitted to this page.

<form action="index.php" method="post">
<input type="hidden" name="Step" value="2">
<table>

for($x=0;$x<$NumChars;$x++)
	{
	echo "<tr>\n\r";
	echo "<td><input type='hidden' name='CharX" . $x ."' value='" . $aCharData[$x][2] . "'></td>\n\r";
	echo "<td><input type='hidden' name='CharY" . $x ."' value='" . $aCharData[$x][3] . "'></td>\n\r";
	echo "<td><input type='radio' name='Char' value='" . $x ."'></td>\n\r";
	echo "<td><input type='text' name='CharCol" . $x ."' value='" . $aCharData[$x][1] . "'></td>\n\r";
	echo "<td><input type='text' name='CharName" . $x ."' value='" . $aCharData[$x][0] . "'></td>\n\r";
	echo "</tr>\n\r";
	}

I check the value of Char and then try and pull the rest of the variables from
form relating to Char's info. I have use this format because there is an image map at the bottom of the page that gives me the x's and y's

after searching and searching ... although I am not happy with it ... I found a way to make it work. for some reason I think post vars are in a differnt collection and are not available to dynamic recusion.

$tmpVar = '$aCharData[$x][1] = ' . "$" . "_POST['CharCol" . $x . "'];" ;
eval($tmpVar);

Ugly, but works
