Nested POST

[scadran]

Hi guys

I have a page in which i will ask the user to enter number of people. according to their answer I will create textbox the same amount as they gave the answer. they complete the text box and i want to send it to the other page by POST. how can I take them in a while loop by the next page? Can someone help me

here are my codes:

 

within the page which create the nested textboxes:

$counter = 1;
while ( $counter <= $no ) 
{
echo "<input type=\"text\" name=\"".'a'."$counter\" size=\"6\">   ";
$counter = $counter + 1;
}
?>

 

within the page which i want to recive them:

 

$result = mysql_query("SELECT * FROM temp") or die(mysql_error());
$row = mysql_fetch_array($result);
$cnt=1;
$new_no = $row[6];
while ( $cnt <= $row[5] )
{
$cd='a'.$cnt;
$code = $_POST['$cd'];
echo $code;
$tyre_arr = mysql_query("select * from tyre where code='$code'") or die(mysql_error());
$tyre = mysql_fetch_array($tyre_arr);
?>

 

I guess there should be something wrong with this line:

$code = $_POST['$cd'];

 

any idea?

Well what is the script doing or not doing? Is there an error? This info should help us figure out where to look and what to look for.

Dont know if i got it completely right but anyway. U can create a hidden input where u pass the number of people the user entered (or just use get for that). When u recieve them make a loop to get the data from post ex:

 

$nrPpl = $_POST['nrpeople'];
for($i=1; $i<=$nrPpl, $i++){
    echo $_POST['input$i'];
}

 

I assumed u named the input boxes as input1, input2 etc. Hope it helped.

Ok i just made a test and u can use count($_POST) to count the number of inputs u have, assuming u have only the input texts passed to post. So:

 

$nrPpl = count($_POST);

 

Also u may have a submit button which is also passed to post, so u can check:

if(array_key_exists('submit', $_POST)){
   $nrPpl = count($_POST) - 1;
} else{
   $nrPpl = count($_POST);
}
