How to fix "Notice : undefined index"

That's mean $_POST['sex'], $_POST['country'] ..... not defined. in other words there no sex,country,city... details posted via form. if your not want to post that details via form simply remove lines 103,104,105,106 lines from code or you can hide this notices via adding 'display_errors(1)' under top of '<?php' tags.

Code:

<?php
    display_errors(1);
    require    'inc/head.inc'; 
    if(!isset($_SESSION['id'])) 
        header('Location:index.php'); 
    else 
        { 
            require 'inc/header.inc'; 
                 
                print    'Update profile or leave blank if you don\'t want to update'; 
                 
                $sql    =    "SELECT * FROM users WHERE id    =    '{$_SESSION['id']}'"; 
                $query    =    @mysql_query($sql, $con); 
                $result    =    @mysql_fetch_array($query); 
                         
                        if(isset($_SESSION['errors'])) 
                                if(is_array($_SESSION['errors'])) 
                                    foreach($_SESSION['errors'] as $error) 
                                        print    $error; 
                                         
                            if(!isset($_POST['count'])) 
                            { 
                                print    '<form action="" method=post> 
                                        <div class=dl>First Name</div>

First $_POST into var to be (check) isset and than assign var into $_SESSION.
And stop adding @ everywhere.

Easy way is to use ternary:

PHP Code:


$var = isset($_POST['var'])/* if isset */ ? htmlentities($_POST['var'], ENT_QUOTES)/* condition true */ : ''/* condition false */;

Now var is defined even if it has no value ( '' ).

Even if i do enter i $_POST['sex'], $_POST['country'], $_POST['city'] and $_POST['relationship'] are assigned i get the same error

Added after 22 minutes:

Oh sorry guys my problem is now solved i had wrong spellings at

PHP Code:


$_SESSSION['sex']            =    @mysql_real_escape_string(htmlentities(stripslashes($_POST['sex'])));
                                    $_SESSSION['country']        =    @mysql_real_escape_string(htmlentities(stripslashes($_POST['country'])));
                                    $_SESSSION['city']            =    @mysql_real_escape_string(htmlentities(stripslashes($_POST['city'])));
                                    $_SESSSION['relationship']    =    @mysql_real_escape_string(htmlentities(stripslashes($_POST['relationship'])));

There are 3 letter "S" instead of only 2 in $_SESSION
