    Programmer Experts,

     

    I'm embarking on an interesting project to gain work experience in php. Just stuck on one thing and wondering if you can help.

    You probably used Team Viewer. This is where I create a Team Viewer session and get a unique number and if I give you it then with that number you can login to my computer and see what is on my screen and you can remotely control my computer.

    Creating something similar. Only difference is, you won't remotely control my computer nor access any parts of my computer but only see what I am viewing in an iframe.

    So, it is like this ...

    I register for a member account. I login to my member account. I add you as "friend". Now, you can view what I am viewing on an iframe.

    My homepage (member account page after I login) will show me 2 iframes. Whatever, I browse on the 1st iframe is remotely viewed by my friends like you. And whatever page you (my friend) is viewing in your 1st iframe gets shown to me on my 2nd iframe.

    So, my 1st iframe records what I'm viewing to show to you, my friend, on your 2nd iframe.

    And my 2nd iframe shows what page you, my friend, are viewing on your 1st iframe inside your member account.

    Simple concept, really. No rocket science.

    So, technically, this is how it works ...

    Whatever url I view in my 1st iframe (whatever url the iframe opens to and whatever links I click inside the iframe) gets recorded onto mysql like so ...

    COLUMN

    User| Latest_Viewing_Url

    UI Man|1.com

     

    Now, your member acc home page would show the webpage I am viewing in your 2nd iframe.

    Your 2nd iframe pulls that (above mentioned mysql data) data and opens to the webpage mentioned on column (Latest_Viewing_Url) position: 0.

    In this example, your 2nd iframe opens to: 1.com.

    When I move-on to another page (eg. by clicking a link on 1.com) then that gets not INSERTED but UPDATED on "Latest_Viewing_Url" column position: 0.

    And things work vice versa for both of us.

    See, I told you it is an interesting project for a beginner like me. Everything is nearly finished. But a problem:

    How do I get the iframe to record (onto "Latest_Viewing_Url" column; pos: 0, all the links I click inside the iframe (in this example the url I visit after clicking a link on 1.com) ?

    I can code for there to be a "Visit" or "Go To Url" button so when I click it then the url in the "Url" html text box gets recorded onto the db. But that is only recording the urls that I view by clicking the "Go" button, Imagine, I clicked a link inside the iframe. Now, that link will have no connection with the "Go" button. hence, I'm in a puzzle how to record what links get clicked. If somehow, I can program the script to monitor the url field on the iframe every 5 secs for any changes so when it finds the url has changed then to record it on the db. But guess what ? I have no clue how to do that. Meaning, how to get the script to monitor what url is residing in the iframe url field. i know how to do this in Ubot Studio (.exe) bot but not php. And so, I need your brilliant help!

    Care to show a few samples for all present and future newbies ? Newbies would appreciate your help for future to come!

    A single line of code that notes down every url that loads in the iframe should do the trick!

    What do you think ?

  • Hi,

    Imagine there is a tbl called "users" and it has a column called "your blog url".
    Now, imagine you want to display that blog's url in an iframe on one of your pages. How would you code it ?
    I did the following but the iframe fails to load the webpage.
    I guess this is due to me failing to get the iframe to pic one url or one entry from the "your blog url" column.

    The best attempt I made was this:

    config.php contains the db connection details and other files.
    I get no erros but I get nothing visible on the screen. Full blank white page!!!



        [code]
        <html>
        <head>
        <title>
        Home Page
        </title>
        </head>
        <body>
        
        <?php
        include 'config.php';
        
        /*Check if user is logged-in or not by checking if session is set or not. 
        If user is not logged-in then redirect to login page. Else, show user's account homepage.*/
        
        if(!isset($_SESSION["user"])) 
        {
            header("location:login.php");
        }
        else 
        {
            $user = $_SESSION["user"];
            $sql = "SELECT * FROM users WHERE usernames = '".$user."'";
            $result = mysqli_query($conn,$sql);
            $numrows = mysqli_num_rows($result);
            if($numrows >1)
            {    
                while ($row = mysqli_fetch_assoc($sql))
                {
                    $db_id = $row["id"];
                    $db_username = $row["usernames"];
                    $db_first_name = $row["first_names"];
                    $db_surname = $row["surnames"];
                    $db_email = $row["emails"];
                    $db_blog_url = $row["blogs_urls"];
            
                    //Welcome user by name.
                    echo "Welcome <b><h2>$db_first_name $db_surname!"?></h2></b>|
        
                    <?php
                    //Display log-out link.
                    echo "<a href='logout.php'>$user Log Out</a>";?>|<br>
            
                    <?php 
                    //Display User's own blog Page in iframe.?>
                    <iframe src="<?php echo $db_blog_url;?>"></iframe>
                    <br>
        
                    <?php 
                    //Display 1st User's blog Page (regardless of who the user is) in iframe.?>
                    <iframe src="<?php echo ".$blogs_urls[0].";?>"></iframe>
                        
                    <?php 
                    //Display All Users' blogs Pages in iframe.?>
                    <iframe src="<?php echo $row['blogs_urls'];?>"></iframe>
                    <?php 
                }
            }        
        }
        ?>
        
        </body>
        </html>
        [/code]    
       
    Ignore the part where my code is not secure from sql injection. I will deal with that later. In the meanwwhile, concentrating on how to fix this frame thing. I attempted 3 different ways to code the iframe to load a webpage but no luck. I don't get any errors but a complete blank page. Error settings is full set to show error messages (config.php):

    /*
    *    ERROR HANDLING
    *    ini_set('display_errors', 1);
    *   ini_set('display_startup_errors', 1);

    *    For All Error, Warning and Notice
    *   error_reporting(E_ALL); OR error_reporting(-1);
    *    For All Errors
    *   error_reporting(E_ERROR);
    *    For All Warnings
    *   error_reporting(E_WARNING);
    *    For All Notice
    *   error_reporting(E_NOTICE);
    */
    error_reporting(E_ALL);</pre>

    PS - The url in db is google.com which is supposed to load in iframe.
