PHP - Add form information to a existing record on database

StackOverflow https://stackoverflow.com/questions/19250797

Вопрос

Hello Stackflow community! I have already done 3 pages and still didn't figure it out. So I have a first page where it shows the username (create or check is exists), until there everything is fine. 

<form name="form1" action= "test3.php" method="post">
Please enter your Username: <input type = "Text" value ="" name = "username"><br />
<input name="cmd_submit" type="submit" id="submit" value="Submit" />
</form>

After this, and as the 'action' says, I have the next php where it checks if the record exists or not and pulls a form.

<?php
if(isset($_POST['mode'])) {
$mode = implode(",", $_POST['mode']);   
} else {
$mode = "";
}
?>


<?php
$dbhost  = 'localhost';
$dbname  = 'dbname';
$dbuser  = 'dbuser';
$dbpass  = 'dbpass'; 

$con = mysql_connect($dbhost, $dbuser, $dbpass);

if($con == FALSE)
{
    echo 'Cannot connect to database' . mysql_error();
}
else
{
    echo 'SUCCESS !';
}

mysql_select_db($dbname, $con);
// Get values from form 
$username = mysql_escape_string($_POST['username']);

if(mysql_num_rows(mysql_query("SELECT * FROM email WHERE username = '".mysql_real_escape_string($_POST['username'])."'")))
{

     echo '<form name="form1" action= "test41.php" method="post">
        <table width="100%" >

mysql_close($con)

Until here everything fine, now it comes my question: after pulling this form I want he infor to save it in the user that is connected to, so if it exists save it on that username, if doesn't (it should be created) create it and save the info in a way that next time shows the checkboxes that they 'checked' checked, and modify that info as they want, and every time pull the info the have 'checked'. And so forth.

So I have another code here for the action of the 2nd form (checkboxes).

<?php
if(isset($_POST['mode'])) {
$mode = implode(",", $_POST['mode']);   
} else {
$mode = "";
}
?>

    <?php
$dbhost  = 'localhost';
$dbname  = 'website';
$dbuser  = 'Test';
$dbpass  = 'password1'; 

$con = mysql_connect($dbhost, $dbuser, $dbpass);

if($con == FALSE)
{
    echo 'Cannot connect to database' . mysql_error();
}
else
{
    echo 'SUCCESS !';
}

mysql_select_db($dbname, $con);
// Get values from form 

$sql="INSERT INTO email(mode) VALUES('$mode')";
$result=mysql_query($sql);



if (!mysql_query($sql, $con))
{
    die('Error: ' . mysql_error());
}
echo "You info has been submitted.";

mysql_close($con)
?>

Thanks, if I didn't explain myself at some point please be nice and let me know, I'm willing to edit or explain it in a comment.

Use this code it can show you error message and if in you field have already used email so it also showing you that error message in differently.

    <?php
//Array to store validation errors
$errmsg_arr = array();

//Validation error flag
$errflag = false;

//Input Validations
if($email == '') {
    $errmsg_arr[] = 'Email Missing';
    $errflag = true;
}
//Check for Duplicate Email
if($email != '') {
    $qry = "SELECT * FROM email WHERE email='$email'";
    $result = mysql_query($qry);
    if($result) {
        if(mysql_num_rows($result) > 0) {
            $errmsg_arr[] = 'Email has Already Taken!';
            $errflag = true;
        }
        @mysql_free_result($result);
    }
    else {
        die("Query failed");
    }
}
//If there are input validations, redirect back to the form
if($errflag) {
    $_SESSION['ERRMSG_ARR'] = $errmsg_arr;
    session_write_close();
    header("location: form.php");
    exit();
}
//Create INSERT Query
$sql="INSERT INTO email(mode) VALUES('$mode')";
$result= @mysql_query($sql);
//Check whether the query was successful or not
if($result) {
    header("location: success.php");
    exit();
}else {
    die("Query failed");
}
?>

And use this code for error message

<?php
if( isset($_SESSION['ERRMSG_ARR']) && is_array($_SESSION['ERRMSG_ARR']) && count($_SESSION['ERRMSG_ARR']) >0 ) {
    echo '<ul class="err">';
    foreach($_SESSION['ERRMSG_ARR'] as $msg) {
        echo '<li>',$msg,'</li>'; 
    }
    echo '</ul>';
    unset($_SESSION['ERRMSG_ARR']);
}
?>

And don't for get Starting Session

<?php session_start(); ?>
