Repeat Region for Variables?

[naveenmedia]

Hi all.

Is there a way to create new variables on the fly?

I have a page with a form, listing data, with a repeat region. Next to each data item is a corresponding checkbox. The name attribute for the checkbox is:

"location<?php echo $row_rs_properties['property_id']?>"

So it comes out to be "location1", "location2", etc. for each respective row.

I'm trying to send this data via e-mail. So I have a script to handle the data, located in a file "refer.php".

In this file, I have the variable

$location = $_POST['location'];

However, this will only read data from a checkbox named "location". Is there a way to dynamically create more variables using the same recordset used to create the additional data and checkboxes?

That way, it automatically creates the variables $location1, $location2, etc. as needed?

Thanks,
Naveen

u cud do some thing like the following. where i assume $total_controls to be the max no of such on the fly controls names needed.

for ($counter = 1 ; $counter < $total_controls ; $counter++)
{
	$location = $_POST['location'. $counter]; 
}

or u cud also go sequentially. (although i dont think u wud be using this method.)

$counter=1;
$location = $_POST['location'. $counter];
$counter++;
$location = $_POST['location'. $counter];
$counter++;

hopefully...with this ur prob is solved....if not feel free to get back.

Define the variable as an array...

$location[]

Then when you call it later, you could use something like:
$countlocations = count($location);
FOR($i = 0; $i < $countlocations; $i++){
echo $location[$i];
}

Thanks! I think it might be working. I also have a variable which displays the actual text in the e-mail message body. It reads:

$mailbody = "Hi $name!\n\n$sendername ($senderemail) thought you would be interested in the following properties: \n\n$location";

As you can see it contains variables. How do I get the $location variable to be listed multiple times?

[PallaviDalvi]

in this case u cud try using the same loop but this time instead of $_POST['location'. $counter ] the variable will be constructed as
${location.$counter}
get back if this doesnt help u.

No, it didn't work. Here is the entire script:

<?
if (!empty($_POST['email']) && !empty($_POST['senderemail'])) {
    $total_controls = 100;
    $email = $_POST['email'];
	$name = $_POST['name'];
	$sendername = $_POST['sendername'];
	$senderemail = $_POST['senderemail'];	
	$link = $_POST['link'];
	$message = $_POST['message'];
	$subject = "$sendername thought you would enjoy this page";
	$mailbody = "Hi $name!\n\n$sendername ($senderemail) thought you would be interested in the following properties: \n\n${location.$counter}";
	$headers = "From: $senderemail\r\n";

for ($counter = 1 ; $counter < $total_controls ; $counter++) { 
    $location = $_POST['location'. $counter];  

}	

mail($email, $subject, $mailbody, $headers);
?>
<div id="message">
	An e-mail was sent to <?PHP echo $name; ?> <a href="mailto:<?PHP echo $email; ?>"><?PHP echo $email; ?></a>, 
	we hope they will enjoy the page at <a href=<?PHP echo $link; ?>><?PHP echo $link; ?></a><br><br>Your message was:<br>
	<?PHP echo $message; ?> <a href=<?PHP echo $link; ?>>Back to page</a>
</div>
<?PHP
}
else {
?>
	<div id="message">
		Please specify both your email and your friend's email addresses.
	</div>
<?PHP
}
?>

I am quite a newbie, so thanks very much for all the help!

You were almost there... a little changes in the code and its order

<? 
$tlocation = "";
if (!empty($_POST['email']) && !empty($_POST['senderemail'])) { 
    $total_controls = 100; 
    $email = $_POST['email']; 
    $name = $_POST['name']; 
    $sendername = $_POST['sendername']; 
    $senderemail = $_POST['senderemail'];     

    $link = $_POST['link']; 
    $message = $_POST['message']; 
    $subject = "$sendername thought you would enjoy this page"; 
for ($counter = 1 ; $counter < $total_controls ; $counter++) {  

    $tempname = "location".$counter;
    $$tempname = $_POST['location'. $counter]; 
   $tlocation .= "\n" . ${$tempname};
} 
$mailbody = "Hi $name!\n\n$sendername ($senderemail) thought you would be interested in the following properties: \n$tlocation";
    $headers = "From: $senderemail\r\n"; 
mail($email, $subject, $mailbody, $headers); 
    ?> 

continue ur remaining script from there on...

NOTE: take a look at $$tempname(Variable Variables)

now variables $location1,$location2 has the values of different locations, if at all you want retrieve them for some other purposes.

Happy Coding,
