reference code is here:
viewtopic.php?t=48349
what the problem is is currently that whole thing just prints out the post entries that you type in, what i need it to do is maybe store every sent post in an array, untill i press another key say "finish" and only then does it send it into the printer to finally print out everything i entered, in the specific collumns and rows ofcourse.
im stuck at that point and i have no idea on how to do it

also need it in a hurry, so any help would be appretiated.

I guess you've already described the solution yourself here... An abstract solution:
Code: Select all
<?php
class Foo {
private $items;
function __construct() {
// initialize an empty array to store the items
$this->items = array();
}
function addItem($item) {
// append the item to the items array
$this->items[] = $item;
}
function sendAndCleanUp() {
foreach($this->items as $item) {
// do something with $item
}
// clean up the items
$this->items = array();
}
}
?>

should this work?
Code: Select all
public $output;
public function __construct()
{
$this->output = array();
}
public function printItems()
{
$sql = 'SELECT * FROM notos';
$result = mysql_query($sql) or die (mysql_error());
while ($info = mysql_fetch_array($result))
{
$summa = $this->getItemSum($info['kogus'], $info['hind']);
$this->output = '
<tr>
<td width="400" height="20" valign="top">'. $info['nimetus'] .'</td>
<td width="100" valign="top">'. $info['markused'] .'</td>
<td width="100" valign="top">'. $info['kogus'] .'</td>
<td width="100" valign="top">'. $info['uhik'].'</td>
<td width="100" valign="top">'. $info['hind'] .'</td>
<td width="98" valign="top">'. $summa .'</td>
</tr>
';
}
}
echo '<pre>';
print_r($this->output);
echo '</pre>';
it should print out the HTML as many times as there are DB entries?

If you try it, you'll know..
Your code always assign the snipped code to this output.
Code: Select all
$this->output = ' .. snipped your code .. ';
You probably want to append it... ( documentation on
array)
Code: Select all
$this->output[] = ' ... code ... ';
And now iterate with foreach over $this->output.
