Echo jQuery loop using PHP

Question

After searching for a long time I've decided to just ask it here, since the things I found either don't work(or I can't get them to work ;)) - or require me to change things on my server, which I would like to avoid.

I want below function to show the output after each result, so the function doesn't have to be loaded first, which takes a long time. My idea, as you can see below, was to try this with jQuery(1.8.2).

It doesn't work and I simply can't get it to work. Is there a better way to do this? Did I make a mistake somewhere causing it not to work?

If you need additional information, please ask.

<?php
print_r($_POST);


if(isset($_POST['p']) && isset($_POST['domain']) && isset($_POST['option']))
{   error_reporting(0);
define('INCLUDE_CHECK',true);
require('admin/API/class_api.php');
require('admin/functions/core.inc.php');

    $dom = explode('.',$_POST['domain']);
    $dom = $dom[0];
    $ext = array('nl','be','eu','net','com','org','biz','info','tk','ws','gr','me','cc','in','gs','name','ch','co','tv','ru','bz','li','lu','pl','se','vg','cx','tl','im','sg','ms','sh','io','mu','fm','am','xxx','ag','sc','nf','md');

    if ($_POST['loop']==40)
     { print 'Laatste loop dus .. STOP : .'.$ext[41]; }
    else
     { print 'Loop: '.$_POST['loop'].' - zoek op : .'.$ext[$_POST['loop']];
       ?>
       <script>
        $.post('test.php', { p:'full', domain:dom, option:opt, loop:'<?php echo $_POST['loop']+1; ?>'},
        function(data){
          $('#domresults2').css('display','block').html(data);
          $('#domloading').css('display','none');
        });
       </script>
       <?php
     }

}
?>




//Start JS
<script>
$('#domsubmit.complete').click( function() {
  var dom = escape($('#domsearch').val());
  var opt = escape($('#option').val());

  $('#domresults2').css('display','none').html('');
  $('#domloading').css('display','inline');

  $.post('test.php', { p:'full', domain:dom, option:opt, loop:0},
     function(data){
       $('#domloading').css('display','none');
       $('#domresults2').css('display','block').html(data);
   });

return false;
});
</script>
//end JS

update : solved!

so, what went wrong? -> the php function in core.inc.php referred to a incompatible with jQuery 1.8.2 lib ('qTip2'). Thanks for the support!

<?php
print_r($_POST);

if (isset($_POST['p']) && isset($_POST['domain']) && isset($_POST['option'])) {
error_reporting(0);
define('INCLUDE_CHECK', true);
require('admin/API/class_api.php');
require('admin/functions/core.inc.php');

$dom = explode('.', $_POST['domain']);
$dom = $dom[0];
$ext = array('nl','be','eu','net','com','org','biz','info','tk','ws','gr','me','cc','in','gs','name','ch','co','tv','ru','bz','li','lu','pl','se','vg','cx','tl','im','sg','ms','sh','io','mu','fm','am','xxx','ag','sc','nf','md');

$loop = $_POST['loop'];
DomCheck($_POST['domain'],$ext[$_POST['loop']]);

if ($loop != count($ext)) {
$loop++;?>
  <script type="text/javascript">
        var opt = '<?php echo $_POST['option']; ?>';
        var dom = '<?php echo $_POST['domain']; ?>';
        $.post('test.php', { p:'full', domain:dom, option:opt, loop:'<?php echo $loop; ?>'},
        function(data){
            $('#domresults2').css('display','block').append(data);
            <?php if ($loop < count($ext)) {
                      echo "$('#domloading').css('display','none');";
                  } ?>
        });
    </script>
<?php
}
}
?>

What is your code doing? You need to explain what you are trying to do as well as just listing your code. — Toby Allen

The PHP-side is waiting for server responses for a whois/dns lookup. The waiting time is way to long, people start to refresh, etc. So the idea is to output every result asap (per result)- to let customers know there is something going on on the background. — Hitman47code

Now, the API that I use has the option to do a single request at a time. The jQuery does not seem to be posting and writing the results with the above code, and with this current setup the PHP-results take to long for a for()-loop Sorry for not explaining, & many thanks for the help! — Hitman47code

One thing you need to understand is that PHP executes on the server and JavaScript (jQuery) executes on the client.

This means that by the time jQuery starts executing, PHP is done.

However, I don't see a loop anywhere in your code. I think this is more of what you wanted. You're not doing a "PHP loop using jQuery," you're outputting jQuery code in a PHP loop:

<?php
if (isset($_POST['p']) && isset($_POST['domain']) && isset($_POST['option'])) {
    error_reporting(0);
    define('INCLUDE_CHECK', true);
    require('admin/API/class_api.php');
    require('admin/functions/core.inc.php');

    $dom = explode('.', $_POST['domain']);
    $dom = $dom[0];
    $ext = array('nl','be','eu','net','com','org','biz','info','tk','ws','gr','me','cc','in','gs','name','ch','co','tv','ru','bz','li','lu','pl','se','vg','cx','tl','im','sg','ms','sh','io','mu','fm','am','xxx','ag','sc','nf','md');

    foreach ($_POST['loop'] as $loop) {
        if ($loop == 40) {
            print "Laatste loop dus .. STOP : .{$ext[41]}";
        } else {
            print "Loop: {$loop} - zoek op : .{$ext[$loop]}";
?>      <script>
            $.post('test.php', { p:'full', domain:dom, option:opt, loop:'<?php echo $loop; ?>'},
            function(data){
                $('#domresults2').css('display','block').html(data);
                $('#domloading').css('display','none');
            });
        </script>
<?php   }
    }
}
?>
