Joining variables, and writing to file

benbox

Hi all!

Ive got a for statement creating a table each with a row of 4 text fields, and one check box.
Each field has _X after it, according to which row. e.g. void_1, void_2 and so on.
void is there so that I can ignor that one if its checked.

So far I have:

for($z=1;$z<=$galsize;$z++) {
$voider = $void . $z ;
if($voider!=1) {
$sect = '$sector' . '$z' ;
$unit = '$unit' . '$z' ;
$pds = '$pds' . '$z' ;
$other = '$other_' . '$z';
fwrite($open, " <a name=\"$z\"></a>");
fwrite($open, "Planet #$z - ");
fwrite($open, "<a href=\"#\">Back to Top</a> ");
fwrite($open, "$sect");
fwrite($open, " ");
fwrite($open, "$unit");
fwrite($open, "$ ");
fwrite($open, "$pds");
fwrite($open, "$ ");
fwrite($open, "$other ");
fwrite($open, "----------------------------");
}
}

This returns something like:

Planet #2 - Back to Top

$sector_$z

$unit_$z$

$pds_$z$

$other_$z

how can I get it so it actually posts what the user enters into the field, as a variable $pds_2 not $pds_$z$

Im really stuck!
Thanks!

check that you have the entire php script inside <? code ... ?> tags. Then, if that still won't work, put the php code at the top of the page and enclosed in a function, then call the function from the part of the page you want.

E.g.

bretticus

use $POST["$pds".$z]
