Question

The following page loads inside of on my index.php. I initially call it using the following link: Import Mutuals

This part works dandy. The problem I’m having is with the refresh code at the bottom: var auto_refresh = setInterval(function(){\$(‘#import’).show(‘fast’).load(‘fb_import_statuses.php?i=$i’).show(‘fast’);}, 1000);

I want it to initially load with record 1 and then keep refreshing, updating my SQL until it reaches record 255. If I do this same code outside of a DIV using Meta Refresh it steps through the sequence fine, but using this JavaScript refresh it will sequence like this:

1, 2, 3, 2, 3, 4, 2, 3, 4, 5 etc…

How can I get it to sequence as 1, 2, 3, 4, 5, 6, 7 etc…

require 'batch_include.php';
require 'html_head.php';

if (isset($_GET['i'])){$i = $_GET["i"];} else {$i=0;}

$getcount = mysql_query("SELECT COUNT(id) AS get_count FROM people", $conn);
while ($row = mysql_fetch_array($getcount)){$get_count = "".$row{'get_count'}."";}

   $result = mysql_query("SELECT id FROM people LIMIT ".$i.",1", $conn);
   while ($row = mysql_fetch_array($result)){                                    
        $get_uid = addslashes("".$row{'id'}.""); 

    $me_friends = $facebook->api(array('method' => 'fql.query', 'query' => 'SELECT     status_id, message, source, time FROM status WHERE uid="'.$get_uid.'" LIMIT 5'));
    foreach ($me_friends as $fkey=>$me_friends){
        $get_status_id = $me_friends['status_id']; 
        $get_message = addslashes($me_friends['message']); 
        $get_source = $me_friends['source']; 
        $get_timestamp = $me_friends['time']; 

    $insert = mysql_query("INSERT INTO statuses (id, message, source, timestamp, uid)      VALUES ('$get_status_id', '$get_message', '$get_source', '$get_timestamp', '$get_uid')",     $conn);        
    }  
}             
$i = $i + 1;

if ($i<=$get_count){
echo "$i";
echo "<script>var auto_refresh = setInterval(function(){\$('#import').show('fast').load('fb_import_statuses.php?i=$i').show('fast');}, 1000);    </script>";
}

else {    
    echo "Import complete:  ";
    echo "<img src='/images/check.png'>";

    } 

Answer 1

the problem is that you add multiple setInterval functions (everytime the page is loaded you echo another method). try putting your refreshing method out of the div or make it call a function that includes php code responsible for retrieving information from db.

if you don’t have to refresh the page every second, you could get all the data from db with one php file and return it in some form (json for example). I think this would be the best way to do this.
