仅重定向到页面一次？

Question

I have this piece of php code that looks up the account prompt function on my website. basically if a user has violated a term and condition on the site, at login they are redirected to a prompt page that says you are very naughty and here's a warning.

My code is this:

 <?php

$account_prompt = account_prompt();
while ($prompt = mysql_fetch_array($account_prompt)) 


 if ($prompt['account_prompt'] == '1')  {
    redirect_to("prompt.php"); 
 }
 ?>

My question is how can i get it to only redirect once? Thanks

Answer 1

He just redirects 1ce unless you are stucked in an endless loop...

Try this

if (isset($prompt['account_prompt']) && $prompt['account_prompt'] == '1')  {
    header("Location: prompt.php"); 
    exit;
}

Use a flag which is set to 1 according to your condition, and take the redirect out of the loop.

           $flag = 0;
           while ($prompt = mysql_fetch_array($account_prompt))  {


                if ($prompt['account_prompt'] == '1') $flag = 1;
            }

            if ($flag == 1)
                  redirect_to("prompt.php");
