[SOLVED] How to create buttons in a loop?

[ali_2kool2002]

can anyone code some basic php to create 4 buttons in a loop , and once created a handling form checks which button is pressed and outputs the value in the hidden input on that button?

Try something like this:

<?php
if (isset($_POST['submitted'])) {
  $button = 0;
  foreach ($_POST as $k => $v) {
    if (preg_match('|^sub_([\d]+)\z|', $k, $match)) {
      $button = $match[1];
    }
  }

  echo "<p>Button $button pressed!</p>\n";
}
?>

<form name="myForm" action="" method="post">
<input type="hidden" name="submitted" value="y" />
<?php
for ($i = 1; $i < 5; $i++) {
  echo "<input type=\"submit\" name=\"sub_{$i}\" value=\"Button $i\" /><br />";
}
?>
</form>

 

Hope this helps
