Block Following Own Account

[justlukeyou]

Hi,

 

I have been trying to set up a social networking button and I have almost completed. However I have approached it from a wrong angle and have one last piece to finish.

 

I can click the "Follow" button and it instantly swaps to "Following" button. It refreshes the page and displays that the user is now following the profile. However the code currently allows someone to follow their own profile. The problem is I dont know how to stop this.

 

I need something which says if $profileid = $followerid dont run code.

 

Does anyone have any suggestions please on how I an prevent this from happening.

 

Alternatively I could hide the follow button if the user is logged in on their own profile but I am stuck on how to do this also.

 

 

<?php
 
$profileid = (int)$_GET['ID'];
$followerid = intval($_SESSION['userID']);



$query = mysql_query("SELECT * FROM follow WHERE user_id = '". $profileid ."' AND follow_user_id= '". $followerid ."'"); 
$duplicatefollow = null;
if (mysql_num_rows($query) > 0) 
{ 
$error['duplicatefollow'] = ''; 
}   



else
{
  
if(isset($_POST['followbutton'])) {


$query = "INSERT INTO `follow` (`user_id`, `follow_user_id`) VALUES ('{$profileid}', '{$followerid}')";
$result = mysql_query($query);



}  
}     
  


  
  $loginprofile = intval($_SESSION['userID']); 
  
  $query_rsSearch = "SELECT * FROM follow WHERE `follow_user_id` = '$loginprofile'";
$rsSearch = mysql_query($query_rsSearch) or die(mysql_error());
$row_rsSearch = mysql_fetch_assoc($rsSearch);
$totalRows_rsSearch = mysql_num_rows($rsSearch);
  
?>

   

 
 <?php
$query = mysql_query("SELECT * FROM follow WHERE user_id = '". $profileid ."' AND follow_user_id= '". $followerid ."'"); 
$duplicatefollow = null;
if (mysql_num_rows($query) > 0) 
{ 
echo '<div class="followbuttonboxsuccess"><img src="/images/following.png" /></div>'; 
} 
else
{
echo '<div class="followbuttonbox"><input name="followbutton" CLASS="submitbutton" type="submit" /></div>'; 
}
?>

isset means does it exist.

Thanks, not totally sure what you mean by that.

 

I think its actually better to hide the button, that should work better.

 

Many thanks.

if (submit button was pressed && they are not trying to follow themselves) {

    add them as a follower to the other person;

}

Hi,

 

This sounds complicated.  I think I will try and hide the button for their own profile.

 

If someone is not logged in I can also display the follow button but link it to the register page.  That may be more intuitive. 

 

Thanks everyone.

Hi,

 

I have managed to edit the code so that it displays a different image if someone is or is not logged in. This helps massively.

 

I am still stuck on how make the code block someone from following themselves.

 

 

 

 

<form method="post" enctype="multipart/form-data">

<?php
 
$profileid = (int)$_GET['ID'];
$followerid = intval($_SESSION['userID']);



$query = mysql_query("SELECT * FROM follow WHERE user_id = '". $profileid ."' AND follow_user_id= '". $followerid ."'"); 
$duplicatefollow = null;
if (mysql_num_rows($query) > 0) 
{ 
$error['duplicatefollow'] = ''; 
}   



else
{
  
if(isset($_POST['followbutton'])) {


$query = "INSERT INTO `follow` (`user_id`, `follow_user_id`) VALUES ('{$profileid}', '{$followerid}')";
$result = mysql_query($query);



}  
}     
  


  
  $loginprofile = intval($_SESSION['userID']); 
  
  $query_rsSearch = "SELECT * FROM follow WHERE `follow_user_id` = '$loginprofile'";
$rsSearch = mysql_query($query_rsSearch) or die(mysql_error());
$row_rsSearch = mysql_fetch_assoc($rsSearch);
$totalRows_rsSearch = mysql_num_rows($rsSearch);
  
?>

   
		 <?php
	     if ($_SESSION['userLoggedIn'])
{ ?>
   <?php
$query = mysql_query("SELECT * FROM follow WHERE user_id = '". $profileid ."' AND follow_user_id= '". $followerid ."'"); 
$duplicatefollow = null;
if (mysql_num_rows($query) > 0) 
{ 
echo '<div class="followbuttonboxsuccess"><img src="/images/following.png" /></div>'; 
} 
else
{
echo '<div class="followbuttonbox"><input name="followbutton" CLASS="submitbutton" type="submit" /></div>'; 
}
?> 

</form>	 <?php
  ;
} else { 
 ?>
 
<div class="followbuttonbox"><a href="/users/register.php"  rel="nofollow" ><img src="/images/follow.png" /></a></div>

<?php
	  }
	  
    
    ?>

I didn't answer that?

I didn't answer that?

But you didn't do it with the EXACT code he can just copy-paste into his script, so he'll keep asking until someone supplies that.

It's a "WHERE poster!=$your_own_id" on the database to prevent someone from following someone, or something like that.
