Help with for statements and arrays

[wheeler08]

I have a page that will generate a specified number of input boxes. The number of boxes created is stored in the variable $number.

On the next page, I want to store each value entered into EACH input box into a variable. I have created the following code that will grab each value and store it in an array. This works. HOWEVER, when I tried to call the values outside of the FOR statement, they are blank.

How can I store an undermined number of values into an undetermined number of variables and be able to call these values later to write to the database or to the screen?

for ($i = 1; $i <= $number; $i++)
{
$textfield[$i] = $HTTP_POST_VARS['textfield'.$i];
}

echo $textfield[$i];

When generaitng you boxes, give them an array name. eg

<input type="text" name="textbox[]">

In your processing page

$boxes = $HTTP_POST_VARS['textbox'];

$boxes is now an array of your textbox entries.

foreach ($boxes as $text) {

  // process the value in $text

}

See if this script helps you....

<?
$how_many_fields = 10;
if($HTTP_POST_VARS){
foreach($text as $k => $v){
echo "i position $k is: $v<br />";
}
}
echo "<form action=\"$PHP_SELF\" method=\"post\">";
for($i=0;$i<=$how_many_fields;$i++){
echo "<input type=\"text\" name=\"text[$i]\" value=\"$text[$i]\" />";
}
echo "<input type=\"submit\" value=\"GO!\" /></form>";
?>
