printing $_POST data to text file

anfetienne

hi i've got this code that writes data to a text file. When i test it with a standard array eg array(1,2,3) it works perfectly fine but when i try it with $_POST['myData'] i get the error message

Warning: Invalid argument supplied for foreach() in /home/theau10/public_html/resources/captionSaveB.php on line 23

Warning: Invalid argument supplied for foreach() in /home/theau10/public_html/resources/captionSaveB.php on line 38

Warning: Invalid argument supplied for foreach() in /home/theau10/public_html/resources/captionSaveB.php on line 53

$file = "upload/$random_digit/gallery.txt";

$imgHandle = fopen($file, 'w+') or die("can't open file");
 
    $iv= 1;

    $lQ = ',';

    $imgAry = $_POST['imageT'];
 
    $stringData = "&imgLoc=";

    fwrite($imgHandle, $stringData);
 
        foreach($imgAry as $key => $value){

            fwrite($imgHandle,$value .$lQ);

        }
 
fclose($imgHandle);
 
$tmbHandle = fopen($file, 'a+') or die("can't open file");
 
    $iv= 1;

    $tQ = ',';

    $tmbAry = $_POST['thumbnailT'];
 
    $stringData = "&tmbLoc=";

    fwrite($tmbHandle, $stringData);
 
        foreach($tmbAry as $key => $value){

            fwrite($tmbHandle,$value .$tQ);

        }
 
fclose($tmbHandle);
 
$capHandle = fopen($file, 'a+') or die("can't open file");
 
    $iv= 1;

    $cQ = ',';

    $capAry = $_POST['captionT'];
 
    $stringData = "&imgCap=";

    fwrite($capHandle, $stringData);
 
        foreach($capAry as $key => $value){

            fwrite($capHandle,$value .$cQ);

        }
 
fclose($capHandle);

it seems that the input values ($_POST['…']) are not arrays. you can check with var_dump().

on the form the names are set on imageT[], thumbnailT[] and captionT[].

once submitted i test to make sure that they are arrays and use print_r and they show as an array perfectly fine
