Question

I am anew to php please help…
I am trying to collect a variable (in specific the counter I used in my loop) on a $_POST after I submit my form.

<form action="reportingTemplate.php" method="post">
<?php
    function buildform() {
    if (file_exists('textt.txt')){

            $x = file_get_contents('textt.txt');
            $y = explode("\r\n", $x);

                $incr = 1;
            foreach ($y as $value) {
            $z = explode(",", $value);

            writehtml($incr,$z[1],$z[2],$z[0]);

      $incr++;
            }   
            if ($incr < 15)
                for ($incr = $incr; $incr<16; $incr++) {
                    writehtml($incr,"","","");

                }
        }
        else
        for ($increm = 1; $increm<16; $increm++) {
            writehtml($increm,"","","");
        }
    }
    ?>
    <input type="hidden" id="test" name"countt" value="<?php echo $incr; ?>"/> <!--error area -->
    <input type="submit"/>
    </form>

where I am getting my $_POST:

$the = $_POST["countt"];
echo $the;

Try it this way:

$incr = 0;
function buildform() {
    global $incr;
    ...
    $incr++;
}

Declare $incr outside the function, then announce that it’s a global variable you’re manipulating from inside function buildform() then you can echo it…
