checkboxes, multi-dim arrays, and forms

[serichens]

I'm trying to pass checkbox data to a confirmation page before
writing to the db. I pull all size data from the db & display the
checkboxes fine. On the confirmation section I want to display all
the sizes, showing the checked ones as checked. My problem: I
don't understand multi dim arrays. How do I pass the both the
checked choices and all possible choices?

Any ideas would be appreciated,
thanks

$sizeN = array();
$allsizes = array();
$status = '

<FORM ACTION= ' . ($PHP_SELF) . ' METHOD=POST>
';

if ($sizeId) {
// data passed from form
// this section isn't working. the key, value is skewed.

while(list($key,$value) = each($sizeId)) {
$status .='keyvalue<input type=\'checkbox\' name=\'sizeId[]\'
value=\''.$key.'\'>'.$value.' <br>';
}

} else { //if ($sizeId)

// sizeId not previously defined
// first time through, or no data passed.

$sizes = mysql_query("SELECT sizeId, size FROM sizes
ORDER by size") or die("size query crashed" . mysql_error());

while ($sizeN = mysql_fetch_array($sizes)) {
$sizeId[$sizeN[0]] = $sizeN[1];
$allsizes[$sizeN[0]] = $sizeN[1];
}
while(list($key,$value) = each($sizeId)) {
$status .='<input type=\'checkbox\' name=\'sizeId[]\'
value=\''.$key.'\'>'.$value.' <br>';
}
} // else

foreach ($allsizes as $key =>$value) {
$status .='<input type=\'hidden\' name=\'allsizes['.$key.']\'
value = \''.$value.'\'>';
}

$status .='
<p><input type=\'submit\' name=\'submitProduct\' value=\'Add
Product\'></form>

';

echo $status;

let me be more specific, maybe somebody will bite. 🙂

<FORM ACTION= ' . ($PHP_SELF) . ' METHOD=POST>
';

if ($sizeId) {
//print data to confirm

$i=0;
$t=0;

while(list($i,$t) = each($allsizes)) {
foreach($_POST['sizeId'] as $key=>$value) {
if (($sizeId[$key]) == ($allsizes[$value])) {

//this should be data checked from submission
$status.='inner loop ch<input type=\'checkbox\' name=\'sizeId[]\' value=\''.$i.'\' checked>'.$allsizes[$value].' <br>';
} else {
//this should be unchecked data
$status.='inner loop un<input type=\'checkbox\' name=\'sizeId[]\' value=\''.$i.'\' >'.$allsizes[$value].' <br>';
}
}
//this should be all other elements unchecked
$status.='outer loop<input type=\'checkbox\' name=\'sizeId[]\' value=\''.$i.'\'>'.$allsizes[$value].' <br>';

$i++;
}

} else { //if ($sizeId)
// no sizeId defined, first time through or no data passed

$sizeN = array();
$allsizes = array();

$sizes = mysql_query("SELECT sizeId, size FROM sizes ORDER by sizeId") or die("size query crashed ". mysql_error());

while ($sizeN = mysql_fetch_array($sizes)) {
$sizeId[$sizeN[0]] = $sizeN[1];
$allsizes[$sizeN[0]] = $sizeN[1];
}
while(list($key,$value) = each($sizeId)) {
$status .='nosizeid<input type=\'checkbox\' name=\'sizeId[]\' value=\''.$key.'\'>'.$value.' <br>';
}
} // else

foreach ($allsizes as $key =>$value) {
$status .='<input type=\'hidden\' name=\'allsizes['.$key.']\' value = \''.$value.'\'>';
}

$status .='<p><input type=\'submit\' name=\'submitProduct\' value=\'Add Product\'></form>';

echo $status;

the problem is in the
while(list($i,$t) = each($allsizes)) {
foreach($_POST['sizeId'] as $key=>$value) {
if (($sizeId[$key]) == ($allsizes[$value])) {
section.

It doesn't loop through the two variables, allsizes & sizeId correctly. I alternate checked and unchecked for only the sizeId[] submitted checked. How can I change that iteration?

Did you figure the above out?

I'm having similar problems..
for:

$Menus = array (   

array ( view=>"false",    edit=>"false",                  remove=>"false",                   active=>"false",            approve=>"false" )                   );

I can get the values from a file and store...
but going from the checkboxes -> array -> file is making me pull my hair out..
any pointers??

Thanks

No, I gave up and re-called the database.

I think the array would be a much better way, but I got pressed for time & had to compromise.

Are you writing the passed data to a temp file? or all possible values?

I'm interested in your approach.
