Question

Basically the code below reads in a text file and diplays it on the screen with checkboxes near each line. But now I want the user to be able to check any box and then display the selected results in a new PHP file – I thought I would have to read in the text file again and somehow refer it to the array, but I’m still stuck, so any help would be appreciated.

Thank you.

First php file

<?php
$filename = "file.txt";
$myarray = file($filename);
print "<form action='file2.php' method='post'>\n";
// get number of elements in array with count
$count = 0; // Foreach with counter is probably best here
foreach ($myarray as $line) {
  $count++; // increment the counter
  $par = getvalue($line);
  if ($par[1] <= 200) {
  // Note the [] after the input name
    print "<input type='checkbox' name='test[$count]' /> ";
    print $par[0]." ";
    print $par[1]." ";
    print $par[2]." ";
    print $par[3]."<br />\n";
  }
}
print "</form>";

Second php file which should display the selected results

<?php
$filename = "file.txt";
$myarray = file($filename);
?>

I think you’re over complicating the problem. You can just give the checkboxes a value atribute and read the array from the second page. Start with kus print_r ($_POST) on the second page to help you see what you have to work with.
