etsted

And i got a file named inbox.page.inc.php that runs the function fetch_conversations_summary()

<?php    $conversations = fetch_conversations_summary();?><div>    <a href="index2.php?page=new_conversation">new conversation</a>    <a href="index2.php?page=logout">Logout</a></div><div class="conversations"><?php    foreach ( $conversations as $conversation ){    ?>    <div class="conversation">        <h2><a href=""><?php echo $conversation['subject'];?></a></h2>        <p>Last reply: <?php echo $conversation['last_reply'];?></p>    </div><?php    }?></div>

so i have changed the code for testing purpose only, instead of $_SESSION['user_id'] i just added 1 instead.

this code is from the file private_message.inc.php<?php        // this will list all of the conversations to one user        function fetch_conversations_summary()        {            global $con;            $sql = "SELECT                     `conversations`.`conversation_id`,                    `conversations`.`conversation_subject`,                     MAX(`conversation_messages`.`message_date`) AS 'conversation_last_reply',                    MAX(`conversation_messages`.`message_date`) > 'conversation_last_reply'                    FROM `conversations`                    LEFT JOIN `conversation_messages` ON `conversations`.`conversation_id` = `conversation_messages`.`conversation_id`                    INNER JOIN `conversation_members` ON `conversations`.`conversation_id` = `conversation_members`.`conversation_id`                    WHERE `conversation_members`.`user_id` = 1                    AND `conversation_members`.`conversation_deleted` = '0'                    GROUP BY `conversations`.`conversation_id`                    ORDER BY `conversation_last_reply` DESC";                                $result = mysqli_query($con, $sql);                        $conversations = array();                        // store all of the id for each conversation, subject and last_reply date            while ( $row = mysqli_fetch_array($result) !== false )            {                $conversations[] = array(                    'id'        =>  $row['conversation_id'],                    'subject'   =>  $row['conversation_subject'],                    'last_reply'=>  $row['conversation_last_reply']                );            }                        return $conversations;        }?>

Every time i run this i get this error:

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 64 bytes) in C:wampwwwcoreincprivate_message.inc.php on line 24

What does that mean?

 

So it is maybe...

 $_SESSION['user_id'] = $user['user_id'];

what do u mean? i dont have a variable named $user.

 

So it is maybe...

 $_SESSION['user_id'] = $user_id;

i changed it to this, then i used print_r, but it still returned 11(it should return 1, as in the DB).

 

This looks illogical...

 $_SESSION['user_id'] = $user_id['user_id'];

Yeah i changed that but still didnt work

okay so now i have test var_dump($_SESSION['user_id'] and it returned 1, then i tried print_r($_SESSION['user_id']) and it returned 11.

// check to see if the post variables are set, then validate them if it equals to true, then log them in    if(isset($_POST['user_name']) && isset($_POST['user_password']) )    {        if( ($user_id =validate_credentials($_POST['user_name'], $_POST['user_password'])) != false)        {            die(var_dump($user_id));            $_SESSION['user_id'] = $user_id['user_id'];                        header("location: index2.php?page=inbox");                        die();        }    }    

i've tried to var_dump $user_id to se what it contains, and it contains 11 when it should contain 1, as thats what the user_id is in the DB

here is how the function that returns the id from the DB looks like

function validate_credentials($user_name, $user_password){    global $con;    $user_name = mysqli_real_escape_string($con, $user_name);    $user_password = mysqli_real_escape_string($con, $user_password);        $sql = "SELECT user_id FROM users WHERE user_name='$user_name' && user_password='$user_password' ";    $query = mysqli_query($con, $sql);    $results = mysqli_fetch_array($query);        if($results == 0)    {        return false;    }        return $results['user_id'];}

Now in my DB i have i have a table called "users" with 3 columns. user_id which is autoincrement, user_name which has the username, and user_password. I dont have a register form, i just make the user in phpmyadmin for testing purpose.

I also tried var_dump($_SESSION);

array (size=1)  'user_id' =>     array (size=2)      0 => string '1' (length=1)      'user_id' => string '1' (length=1)

array (size=2)0 => string '1' (length=1)'user_id' => string '1' (length=1)

the problem is that $_SESSION['user_id'] somehow returns an array

test php file

why is $_SESSION['user_id'] an array?

 

I just think you need to be careful that Php doesn't turn...

'conversations'.'conversation_subject'

...into...

conversationsconversation_subject

I didnt think so either

But any help on my problem?

conversations table:

conversation_id.

conversation_subject.

conversations is a table that creates an id foreach conversation and stores the subject of each conversation.

conversation_members table:

id.

conversation_id.

user_id.

conversations_last_view

conversation_deleted.

the conversation_id corresponds to the conversation_id inside the conversations table. user_id is the id of each user. conversations_last_view is the date of when someone last viewed the conversation. conversation_deleted tells wheter a user has deleted the conversation.

conversation_messages table:

message_id.

conversation_id.

user_id.

message_date.

message_text.

message_id i autoincrement. the conversation_id corresponds to the conversation_id inside the conversations table. user_id is the id of each user. message_date tellst when the last message was implemented. message_text holds the message.

I have fixed the error, but now face antoher one.

SELECT                     `conversations`.`conversation_id`,                    `conversations`.`conversation_subject`,                     MAX(`conversation_messages`.`message_date`) AS 'conversation_last_reply',                    MAX(`conversation_messages`.`message_date`) > 'conversation_last_reply'                    FROM `conversations`                    LEFT JOIN `conversation_messages` ON `conversations`.`conversation_id` = `conversation_messages`.`conversation_id`                    INNER JOIN `conversation_members` ON `conversations`.`conversation_id` = `conversation_members`.`conversation_id`                    WHERE `conversation_members`.`user_id` = {$_SESSION['user_id']}                    AND `conversation_members`.`conversation_deleted` = '0'                    GROUP BY `conversation`.`conversation_id`                    ORDER BY `conversation_last_reply` DESC

this keeps giving me an error: Unknown column 'Array' in 'where clause'

What this SQL statement is supposed to do is select all of a users messages from the database.

Ive tried to print_r $_SESSION['user_id'] and got this: Array ( [0] => 1 [user_id] => 1 )

im not sure why the [0] => 1 is there, but this is how i make the session.

if( ($user_id = validate_credentials($_POST['user_name'], $_POST['user_password'])) != false)        {            $_SESSION['user_id'] = $user_id;                        header("location: index2.php?page=inbox");                        die();        }

this is supposed to check if the user exist, if so then create a session.

this i the content of validate_credentials

function validate_credentials($user_name, $user_password){    global $con;    $user_name = mysqli_real_escape_string($con, $user_name);    $user_password = mysqli_real_escape_string($con, $user_password);        $sql = "SELECT user_id FROM users WHERE user_name='$user_name' && user_password='$user_password' ";    $query = mysqli_query($con, $sql);    $results = mysqli_fetch_array($query);        if($results == 0)    {        return false;    }        return $results;}

keep getting this error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '.'conversation_id', 'conversations'.'conversation_subject' ' at line 2

$sql = "SELECT                     'conversations'.'conversation_id',                    'conversations'.'conversation_subject'                    MAX('conversation_messages'.'message_date') AS 'conversation_last_reply'                    FROM 'conversations'                    LEFT JOIN 'conversation_messages' ON 'conversations'.'conversation_id' = 'conversation_messages'.'conversation_id'                    INNER JOIN 'conversation_members' ON 'conversations'.'conversation_id' = 'conversation_members'.'conversation_id'                    WHERE 'conversation_members'.'user_id' = {$_SESSION['user_id']}                    AND 'conversation_members'.'conversation_deleted' = '0'                    GROUP BY 'conversation'.'conversation_id'                    ORDER BY 'conversation_last_reply' DESC";

 

Another problem is that the function heidi() isn't global, it's not accessible from the element's onclick scope. Put the function declaration outside of the .ready() handler.

 

The hilsen="heidi" syntax doesn't work in Javascript, that's a C++ / Java / PHP thing. If you want to give a default value then you'll have to set it inside the function:

function heidi(hilsen) {    if(typeof hilsen == "undefined") {        hilsen = "heidi";    }

But if i would to call that function, would it still wait for the page to load, before running whats inside the jquery function, since the jquery ready function is set?

ive updated it a little, i thought it would help

still didnt work

what do u suggest?

I think i have been using jquery wrong, or maybe not the best way. I want to wrap jquery outside javascript functions, to make sure that the page i fully loaded, so that i wont have any cached files, when i make a request with ajax.

<!DOCTYPE html><html><head><script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script><script>$(document).ready(function(){  $("#statusBtn").click(function(){    function heidi(hilsen="heidi"){     return hilsen;    }document.write(heidi());  });});</script></head><body><button id="statusBtn" onclick="heidi('lars')">klikk</button></body></html>

Now i have tried this an it works, except not the way i want, the parameter "lars" is not being set, and this returns "heidi" instead

At top i have a variable that checks to see which of the page the user is on

$check_document = $_SERVER['PHP_SELF'];    if($check_document == "/watch.php")    {        $DB_table = "comments";    }    else if($check_document == "/user.php")    {        $DB_table = "status";    }

this is the reply textarea

$statuslist .= '<textarea id="replytext_'.$statusid.'" class="replytext" onkeyup="statusMax(this,250)" placeholder="write a comment here"></textarea><button id="replyBtn_'.$statusid.'" onclick="replyToStatus('.$statusid.',''.$u.'','replytext_'.$statusid.'',this,''.$DB_table.'')">Reply</button>';	    

this is the javascript that is supposed to handle the input the user just typped in, then send it of to php_parsers/status_system2.php

function replyToStatus(sid,user,ta,btn,document) {    $(document).ready(function(){        // sid holds the id that associate each thread with all of its replies         // get the values inside the textarea    var data = _(ta).value;        if(data === ""){        alert("Type something first");        return false;    }            // select the buttons id    _("replyBtn_"+sid).disabled = true;            $.post("php_parsers/status_system2.php","action=status_reply&sid="+sid+"&user="+user+"&data="+data+"&document="+document,function(information){            // split the incoming string, to get the last inserted id            var datArray = information.split("|");                            if(datArray[0] === "reply_ok"){                // contains the last inserted id to the DB                var rid = datArray[1];                                // sanitize the data, the user wrote in                data = data.replace(/</g,"<").replace(/>/g,">").replace(/n/g,"<br />").replace(/r/g,"<br />");                                // contains the reply                _("status_"+sid).innerHTML += '<div id="reply_'+rid+'" class="reply_boxes"><div><b>Reply by you just now:</b><span id="srdb_'+rid+'"><a href="#" onclick="return false;" onmousedown="deleteReply(''+rid+'','reply_'+rid+'');" title="DELETE THIS COMMENT">remove</a></span><br />'+data+'</div></div>';                _("replyBtn_"+sid).disabled = false;                                // empty the textarea                _(ta).value = "";            } else {                alert(information);            }                        });    });};

this is the ajax that will hande the AJAX call

//action=status_reply&sid="+sid+"&user="+user+"&data="+dataif (isset($_POST['action']) && $_POST['action'] == "status_reply" && !empty($_POST['document']) ){        // Make sure data is not empty    if(strlen($_POST['data']) < 1){       echo "data_empty";       exit();    }        // Clean the posted variables    $osid = preg_replace('#[^0-9]#', '', $_POST['sid']);    $account_name = preg_replace('#[^a-z0-9]#i', '', $_POST['user']);    $data = htmlentities($_POST['data']);    $data = mysqli_real_escape_string($con, $data);        // Make sure account name exists (the profile being posted on)    $sql = "SELECT COUNT(id) FROM register WHERE u_name='$account_name' AND activated='1' LIMIT 1";    $query = mysqli_query($con, $sql);    $row = mysqli_fetch_row($query);        if($row[0] < 1){        echo "the user doesnt exist";        exit();    }        // check to see which page the user is on, then give different variables that contain different DB tables// check to see whether or not the user replied to a status from user.php or watch.php    if($_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";    }        // Insert the status reply post into the database    $sql = "INSERT INTO $DB_table(osid, account_name, author, type, data, postdate)           VALUES('$osid','$account_name','$log_username','b','$data',now())";    $query = mysqli_query($con, $sql);        // get the inserted id    // to allows the writer or the account owner to delete the reply    $id = mysqli_insert_id($con);        // Insert notifications for everybody in the conversation except this author    $sql = "SELECT author FROM $DB_table WHERE osid='$osid' AND author!='$log_username' GROUP BY author";    $query = mysqli_query($con, $sql);        while ($row = mysqli_fetch_array($query, MYSQLI_ASSOC)) {        $participant = $row["author"];        $app = "Status Reply";        $note = $log_username.' commented here:<br /><a href="user.php?u='.$account_name.'#status_'.$osid.'">Click here to view the conversation</a>';        mysqli_query($con, "INSERT INTO notifications(username, initiator, app, note, date_time)                     VALUES('$participant','$log_username','$app','$note',now())");    }    echo "reply_ok|$id";    exit();}

<textarea id="replytext_8" class="replytext" onkeyup="statusMax(this,250)" placeholder="write a comment here"></textarea><button id="replyBtn_8" onclick="replyToStatus(8,'george','replytext_8',this,'comments')">Reply</button>

If you need to know, the content of the reply textarea looks like this, but i think i have a cache problem

They get set when a user fills up a textarea, and hits a button.

$statuslist .= '<textarea id="replytext_'.$statusid.'" class="replytext" onkeyup="statusMax(this,250)" placeholder="write a comment here"></textarea><button id="replyBtn_'.$statusid.'" onclick="replyToStatus('.$statusid.',''.$u.'','replytext_'.$statusid.'',this,''.$DB_table.'')">Reply</button>';
