[PHP] Dynamic Arrays
I have an array question. I want to use a dynamic array but I don't know how to do this. What I want to do is this, I want to write a form script that takes the elements of the form and submits them in the array then I want to do a loop and check to see if each element in the array has a value and then if it does bullocks for them, but if it doesn't then I want it to come to a screeching halt and tell them what dolts they are for missing a field. So basically I want to have a Required field option for the form. I'm still learning arrays and dynamic arrays are just throwing me and I can't find a good code example to work from.

Here's an example of what I think you're after:
?
$fields = array(
'name' = 'Name: input name=name',
'age' = 'Age: input name=age',
'eyes' = 'Eyes: input type=radio name=eyes value=blue Blue
input type=radio name=eyes value=brown Red'
);
if (isset($_REQUEST['form_posted']))
{
$missing_field = 0;
$good_fields = '';
foreach ($fields as $name = $html)
{
if (!($val = $_REQUEST[$name]))
{
if (!$missing_field)
echo form method='post' action='{$_SERVER['PHP_SELF']}';
echo PThe following field is mandatory:br$html/p;
$missing_field = 1;
}
else
$good_fields .= input type='hidden' name='$name' value='$val';
}
if ($missing_field)
{
echo $good_fields
. 'input type=submit name=form_posted/form';
exit;
}
else
{
echo pThank you for your input! Here's what we got:/pul;
foreach (array_keys($fields) as $name)
echo li$name: {$_REQUEST[$name]}/li;
echo '/ul';
}
}
else
{
echo form method='post' action='{$_SERVER['PHP_SELF']}';
foreach ($fields as $f)
echo $fbr;
echo 'input type=submit name=form_posted/form';
}
?

Re: [PHP] Dynamic Arrays
Hi Folks:
I was going to propose something similar. Allow me to tweak:
form
*input type=text name=my_array[foo] value=
*input type=text name=my_array[bar] value=
input type=text name=my_array[blankable] value=
/form
on you script page
?
# $mand = array(foo, bar);
$mand = array('foo', 'bar');
# $cnt = count($mand);
# for ($i = 0; $i $cnt; $i++)
# if (!in_array($mand[$i], $my_array))
#echo Error: You missed a required field - .$mand[$i].br\n;
$Prob = array();
while ( list(,$Key) = each($mand) ) {
if ( empty($_POST[$Key]) ) {
$Prob[] = $Key is a required field;
}
}
if ( !empty($Prob) ) {
echo ul\n;
while ( list(,$Val) = each($Prob) ) {
echo li$Val./li\n;
}
echo /ul\n;
} else {
# Go ahead. Fields are filled in.
}
?
Enjoy,
