Dynamic Table

[proctk]

Hi the below is code that is supposed to add the number of rows that is selected form the first select box. So if the number twenty is selected then that number of of rows will display.  The code works but with one BIG problem.  it works backwards. If the number 1 is selected twenty rows are displayed and if the number 20 is selected one row is selected.

 

Any ideas how to fix this thank you

<form name="numItems" method="post" action="<?php $PHP_SELF; ?>">

  <select name="numItems" id="numItems" onchange="this.form.submit()">
<?php
$items = $_POST['numItems'];
foreach(array("","01","02","03","04","05","06","07","08","09","10","11","12","13","14","15",
"16","17","18","19","20") as $value)

{
  echo "<option value='$value'";
  if($value == $items)
  {
    echo " selected='selected'";
  }
  echo ">$value</option>\n";
}
?>
  </select>

I'm not sure I understand what you mean

[code]first off this don't make sense

<form name="numItems" method="post" action="<?php $PHP_SELF; ?>">

 

  <select name="numItems" id="numItems" onchange="this.form.submit()">

<?php

$items = $_POST['numItems'];

foreach(array("","01","02","03","04","05","06","07","08","09","10","11","12","13","14","15",

"16","17","18","19","20") as $value)

 

{

  echo "<option value='$value'";

  if($value == $items)

  {

    echo " selected='selected'";

  }

  echo ">$value</option>\n";

}

?>

[/code]

 

secondly your issue is in the logic of your while loop

 

you have it in the form while A <= B  where B is a constant and A is your user's input.  So you have B=20 and if A = to 1 it will need to loop through enough times to get to 20 (I.e 21 times)  so what I suggest you do is say  while ($i <= $user_input)  where $i is initialized at a value of 1 and $user_input is the user input. 

 

Can you explain the purpose of the foreach loop in the above?  Pre selecting/creating a selection is way easier
