Question

I’m trying to insert my comment content with Ajax. But I believe I’m having trouble with the comment_add.php page and wondered if someone could take a look for me.

Getting the streamid seems to work as I’ve checked in firebug, but it shows no content. So I don’t know whether I may have missed something that I can’t see but someone else might be able to find. Or maybe I just haven’t written the comment_add page properly.

FORM

echo "<form id='addcomment' method='POST' class='form_statusinput'>
<input type='hidden' name='posterid' id='posterid' value='".$user1_id."'>
<input type='hidden' name='streamid' id='streamid' value='".$streamitem_data['streamitem_id']."'>
<input name='content' id='content' placeholder='Comment..' autocomplete='off'>
<input type='submit' id='button' value='Feed'>
</form>";

AJAX

<script>
$(document).ready(function(){
$("form#addcomment").submit(function(event) {
event.preventDefault();
var content = $("#content").val();
var streamid = $("#streamid").val();

$.ajax({
type: "POST",
url: "comment_add.php",
dataType: "json",
data: {content:content,streamid:streamid}, 
success: function(response){ 
$("#commentaddid").prepend(""+content+"");
}
});
});
});
</script>

COMMENT_ADD.PHP

<?php
session_start();
require"include/load.php";
$user1_id=$_SESSION['id'];
if(isset($_POST['streamid'])&isset($_POST['content'])){
if($_POST['content']){
rawfeeds_user_core::add_comment($_POST['streamid'],$_POST['content']);
}
}
?>

FUNCTION

public function add_comment($streamid,$content){
            $content =  mysql_real_escape_string($content);
            $content =  strip_tags($content);

            $content = preg_replace('/(?<!S)((http(s?):\/\/)|(www.))+([\w.1-9\&=#?\-~%;\/]+)/','<a href="http$3://$4$5">http$3://$4$5</a>', $content);

            if(strlen($content)>0){
            $insert = "INSERT INTO streamdata_comments(comment_poster, comment_streamitem, comment_datetime, comment_content) VALUES (".$_SESSION['id'].",$streamid,UTC_TIMESTAMP(),'$content')";
                        echo $insert;

            $add_post = mysql_query($insert) or die(mysql_error());
            }
            return;
    }

Answer 1

change

success: function(response){ 
$("#commentaddid").prepend(""+content+"");
}

to

success: function(response){ 
$("#commentaddid").prepend(""+response+"");
}

because content doesn’t exist in that function

AND

your links wouldn’t be <a>‘s

EDIT 2
Because you wanted to add the data from the other side here is a little hack you can use to get content

$.ajax({
type: "POST",
url: "comment_add.php", 
dataType: "json",
_content:content,
data: {content:content,streamid:streamid},  
success: function(response){  
    $("#commentaddid").prepend(""+this._content+""); 
} 
});

This is possible because the constructor loop through the object and sets it to this
