PHP Form: After getting results adding a new table row when entering new information
Although probarly quite simple, i cannot seem to find the following.
The form takes certain data, and then represents the data in a table.Next step i click the hyperlink that takes me back to the form.
Now my question is how exactly do i make it possible when filling in the same form again so both results are displayed in the same table? Then filling in a other form with data adds another row and so on.Regards.
The code below (pardon me that it is not english).
<?php
session_start();

Your session variables will only store the last piece of data entered. Rather than storing them in the session as simple variables, try putting an array in the session. Then when the form is submitted again, add another entry to those arrays. That way you won't overwrite what was previously there.
ETA:
On Page 1, where you set the session variables, try this:
$_SESSION["standnaam"][]=$standnaam;
$_SESSION["oppervlakte"][]=$oppervlakte;
$_SESSION["verdieping"][]=$verdieping;
$_SESSION["telefoon"][]=$telefoon;
$_SESSION["netwerk"][]=$netwerk;
On Page 2, where you write out the table rows, try this:
for($i = 0; $i < count($standnaam); $i++) {
echo "<tr>";
echo "<td>".$standnaam[$i]."</td>";
echo "<td>".$oppervlakte[$i]."</td>";
echo "<td>".$verdieping[$i]."</td>";
echo "<td>".$telefoon[$i]."</td>";
echo "<td>".$netwerk[$i]."</td>";
echo "<td>".$totalePrijs[$i]."</td>";
echo "</tr>";
}
I think that aught to do it.
