checkbox & php4

[Anon]

Hi,
It's all over these pages but almost all the time it concerns php3.
I am using php4 and I just can't get the hang of checkboxes and their arrays

I have php script that creates a number of checkboxes from an Databasetable.
These are then stored under the name titel[]
now i should be able to summon them using
a printf or echo $titel[0] or titel[1]. here is the script i am using. according to a program i have written it submits the values titel wich is an array and submit.
but I can't use them.
can somebody please help me?

<?php
$result = mysql_db_query ("setf","select ond_id, titel from onderwerpen ");
?>
<FORM action="print.php" method="post">
<?php
while ($myrow = mysql_fetch_array($result)){
?>
<INPUT type="checkbox" name="titel[]" value="<?php $myrow["titel"] ?>"> <?php echo $myrow["titel"] ?><BR>
<?php
}
?>
</SELECT>
<INPUT type="submit" name="submit" value="submit">
</P>
</FORM>

Try a slight change, this is the way I handle check boxes, might be a good method, it always works for me:

for ($i=0;$i<$num_checkboxes;$i++) {

PRINT"<INPUT type=\"checkbox\" name=\"titel_".$i."\" value=\"".$myrow["titel"]."\">";

}

on the processing page you get the values out by:

$the_values = array();
for ($i=0;$i<$num_checkboxes;$i++) {
$info="titel_".$i;
$the_values[$i]=$$info;
}

heeft value een waarde?
