Question

I’ve got my script working, but only 1 result shows up. What do I need to add to get next ten results from my database. I’ve provided small portions of the code which I feel are the most important for doing this.

AJAX

 <script type="text/javascript">
$(function() 
{
$('.load_more').live("click",function() 
{
var ID = $(this).attr("id");
if(ID)
{
$("#load"+ID).html('Loading...');

$.ajax({
type: "POST",
url: "include/load_more_home_posts.php",
cache: false, 
dataType: "json",
data: { streamitem_id: ID},
cache: false,
success: function(response){
$("#articles").prepend("<div id='divider-"+response['streamitem_id']+"'><div class='userinfo'><a href='/profile.php?username="+response['username']+"'><img class='stream_profileimage' style='border:none;padding:0px;display:inline;' border=\"0\" src=\"imgs/cropped"+response['id']+".jpg\" onerror='this.src=\"img/no_profile_img.jpeg\"' width=\"40\" height=\"40\" ></a><div class'delete' style='cursor:pointer;position:relative;top:0px;float:right;padding-right:5px;' onclick=\"delete_('"+response['streamitem_id']+"');\">X</div><a href='/profile.php?username="+response['username']+"'>"+response['first']+" "+ response['middle']+" "+response['last']+"</a><span class='subtleLink'> said</span><br/><a class='subtleLink' style='font-weight:normal;'>"+response['streamitem_timestamp']+"</a><hr>"+response['streamitem_content']+"<div style='height:20px;' class='post_contextoptions'><div id='streamcomment'><a style='cursor:pointer;' id='commenttoggle_"+response['streamitem_id']+"' onclick=\"toggle_comments('comment_holder_"+response['streamitem_id']+"');clearTimeout(streamloop);swapcommentlabel(this.id);\">Write a comment...</a></div><div id='streamlike'><a title='Like "+response['first']+" "+ response['middle']+" "+response['last']+"s status' id='likecontext_"+response['streamitem_id']+"' style='cursor:pointer;' onClick=\"likestatus("+response['streamitem_id']+",this.id);\"><div style='width:50px;' id='likesprint"+response['streamitem_id']+"'>Like</a></div><div style='width:50px;' id='likesprint"+response['streamitem_id']+"'><a title='See who likes "+response['first']+" "+ response['middle']+" "+response['last']+"s status' href='include/likes.php?streamitem_id="+response['streamitem_id']+"' /></a></div></div></form></div><div id='streamdislike'><a id='dislikecontext_"+response['streamitem_id']+"' style='cursor:pointer;' onClick=\"dislikestatus("+response['streamitem_id']+",this.id);\"><div style='width:70px;' id='dislikesprint"+response['streamitem_id']+"'>Dislike</a></div><div style='width:70px;' id='dislikesprint"+response['streamitem_id']+"'></div></div></form><div class='stream_comment_holder' style='display:none;' id='comment_holder_"+response['streamitem_id']+"'><div id='comment_list_"+response['streamitem_id']+"'></div><div class='stream_comment_inputarea'><form id='mycommentform' method='POST'  class='form_statusinput'>\

// remove the previous load more link
$("#load"+ID).remove();
}
});
}
return false;
});
});
</script>

Answer 1

Right now you are not looping through your result set and therefore you are only fetching one row. Try the following, which splits your $json array into three arrays (streams, comments, users), which in turn are arrays (one for each row). Note that you will have to change your jQuery code accordingly.

/***** STREAMS *****/
$chant = mysqli_query($mysqli, $call) or die(mysqli_error($mysqli));
$json = array();
$json['streams'] = array();

while ($resultArr = mysqli_fetch_assoc($chant)) {
    $arr = array();
    $arr['streamitem_id'] = $resultArr['streamitem_id'];
    $arr['streamitem_content'] = $resultArr['streamitem_content'];
    $arr['streamitem_timestamp'] = Agotime($resultArr['streamitem_timestamp']);

    $json['streams'][] = $arr;
}

/***** COMMENTS *****/
$check = "SELECT comment_id, comment_datetime, comment_streamitem, comment_poster, comment_content FROM streamdata_comments WHERE comment_poster=".$following_string."  ORDER BY comment_datetime DESC";
$check1 = mysqli_query($mysqli,$check);
$json['comments'] = array();

while ($resultArr = mysqli_fetch_assoc($check1)) {
    $arr = array();
    $arr['comment_id'] = $resultArr['comment_id'];
    $arr['comment_content'] = $resultArr['comment_content'];
    $arr['comment_poster'] = $resultArr['comment_poster'];
    $arr['comment_datetime'] = Agotime($resultArr['comment_datetime']);
    $arr['comment_streamitem'] = $resultArr['comment_streamitem'];

    $json['comments'][] = $arr;
}

/***** USERS *****/

$check = "SELECT * FROM users WHERE id=".$following_string."";
$check1 = mysqli_query($mysqli,$check);
$json['users'] = array();

while ($resultArr = mysqli_fetch_assoc($check1)) {
    $arr = array();
    $arr['username'] = $resultArr['username'];
    $arr['id'] = $resultArr['id'];
    $arr['first'] = $resultArr['first'];
    $arr['middle'] = $resultArr['middle'];
    $arr['last'] = $resultArr['last'];

    $json['users'][] = $arr;
}


echo json_encode($json);

As for the jQuery, I will just show you an example of what you can do because I don’t know what your DOM looks like, and your code is not that simple. You should be able to update your code without any major headaches.

success: function(response) {
    // Streams
    $.each(response.streams, function(i, stream) {
        alert(response.streams[i].streamitem_id);
    });

    // Comments
    $.each(response.comments, function(i, comment) {
        alert(response.comments[i].comment_id);
    });

    // Users
    $.each(response.users, function(i, user) {
        alert(response.users[i].id);
    });
}

Edit: In the above, it would be prettier to use the stream, comment and user variables directly instead of looking up at the arrays at position i.

Also, I would suggest that you split your script into several scripts which have a more narrow focus.
