ajax return false, then true


Recommended Posts

I have a script that allows me to post comments, but when i try to delete that comment i get a error message telling me that a specific variable is undefined. I refresh the page and try again, and suddently it works.




if($author == $log_username || $account_name == $log_username ){
        $statusDeleteButton = '<span id="sdb_'.$statusid.'"><a href="#" onclick="return false;" onmousedown="deleteStatus(\''.$statusid.'\',\'status_'.$statusid.'\',\''.$DB_table.'\');" title="DELETE THIS STATUS AND ITS REPLIES">delete status</a></span>    ';

  function deleteStatus(statusid,statusbox,document){
    var ajax = ajaxObj("POST", "php_parsers/status_system2.php");
    ajax.onreadystatechange = function() {
        if(ajaxReturn(ajax) === true) {
            if(ajax.responseText === "delete_ok"){
                // remove the div all of the tekst is inside, the textarea and the reply button
                _(statusbox).style.display = 'none';
                _("replytext_"+statusid).style.display = 'none';
                _("replyBtn_"+statusid).style.display = 'none';
            } else {


    // fires of when the someone deletes a thread
if (isset($_POST['action']) && $_POST['action'] == "delete_status" && !empty($_POST['document'])){
    if(!isset($_POST['statusid']) || $_POST['statusid'] == ""){
        echo "status id is missing";
    // sanitize the inserted status id
    $statusid = preg_replace('#[^0-9]#', '', $_POST['statusid']);
    // check to see which page the user is on, then give different variables that contain different DB tables
    // check to see whether or not the user replied to a status from user.php or watch.php
    if($_POST['document'] == "comments") // this means the user replied within watch.php
        $DB_table = "comments";
    else if($_POST['document'] == "status") // this mean that the user replied within user.php
        $DB_table = "status";
        echo 'Error: this is an unexpected situation. What is happening? ' . $_POST['document'];
    // Check to make sure the person deleting this reply is either the account owner or the person who wrote it
    if($DB_table == null){
  echo 'Can\'t look up nuthin';
   // Check to make sure the person deleting this reply is either the
   //account owner or the person who wrote it
    $sql =  "SELECT account_name, author FROM $DB_table WHERE id='$statusid' LIMIT 1";
    $query = mysqli_query($con, $sql);
    while ($row = mysqli_fetch_array($query, MYSQLI_ASSOC)) {
        $account_name = $row["account_name"];
        $author = $row["author"];
    // delete the thread and it replies with the same osid
    if ($author == $log_username || $account_name == $log_username) {
        $sql = "DELETE FROM $DB_table WHERE osid='$statusid'";
        mysqli_query($con, $sql);
       echo "delete_ok";
