我们可以通过PHP中的POST和GET标记传递多个变量

Question

I ran two SQL queries in a page and want to pass those variable to anotherpage.. i know that i can pass one variable attached it to the anchor link but can we do that for two variables with single link?

The usual passing single variable:

<a href="page2.php?id=<?php echo $row['variable1'];?>" ><li style="font-size:14px;"><strong>LINK</strong></li></a>

On the other page(#2) we can call the passed variable using $id = $_GET["id"]; method..

Now as per my situation, is it possible for two variables:

<a href="page2.php?id=<?php echo $row['variable1'];?> ?id2=<?php echo $row2['variable2'];?>" ><li style="font-size:14px;"><strong>LINK</strong></li></a>

If it is possible, did i done anything wrong in the above code... Any Help is Appreciated..

You forgot to use the Ampersand char to add more variables "&"

try do some more nice code and cleaning some non acceptable chars in your case with the $_GET method.

<?php
function cleanvar($str) {
        $str = @trim($str);
        if(get_magic_quotes_gpc()) {
            $str = stripslashes($str);
        }
        return mysql_real_escape_string($str);
    }

    $var_1 = cleanvar($row['variable1']);
    $var_2 = cleanvar($row['variable2']);

?>

<a href="page2.php?id=<?php echo $var_1;?>&id2=<?php echo $var_2;?>"><li style="font-size:14px;"><strong>LINK</strong></li></a>

Maybe you can use some referer param like " &referer=mypage1.php" and create some condition like

if($_GET['referer'] == 'mypage1.php'){ //save or do something }else{ //nothing or do somthing}

hoping that helps you
