This should work

if(isset($_POST['name']) && $_POST['name']=="save1")
{
    $accout_f = mysql_real_escape_string($_POST['facebook']);
    mysql_query("INSERT INTO  accounts (account) VALUES ('$accout_f') WHERE name='facebook'");
}
    elseif(isset($_POST['name']) && $_POST['name']=="save2")
{
    $accout_t = mysql_real_escape_string($_POST['twitter']);
    mysql_query("INSERT INTO  accounts (account) VALUES ('$accout_t') WHERE name='twitter'");
 }

but it's not the way that I'd go about it. Your form means that you can only add one field at a time. It may be better if an user could add both on a single button click.

OK, my mistake:

if(isset($_POST['save1']))
{
$accout_f = mysql_real_escape_string($_POST['facebook']);
mysql_query("INSERT INTO  accounts (account) VALUES ('$accout_f') WHERE name='facebook'");
}
elseif(isset($_POST['save2']))
{
$accout_t = mysql_real_escape_string($_POST['twitter']);
mysql_query("INSERT INTO  accounts (account) VALUES ('$accout_t') WHERE name='twitter'");
 }

Have you echoed anything in the code to see where you're going wrong?

e.g. echo $_POST['facebook'];etc?

Also you you just use an 'insert and go'. Add some error handling.

This will happen before you submit the form as the 'sent' vars don't exist yet. Does it still happen after submit?

Hi,

I think you need to focus more on validating which submit buttons were click. You have two of them. If I click one only, then on POST, you will get the undefined index error on the other.

Why not try validating your form submission based on the submit button clicks. for example

  if((isset($_POST['save1'])) || (isset($_POST['save']))){

   ## check here which one is not empty, and then prepare it for the database inclusion or posting.


  }

Please forgive my vigorous use of parenthesis. I can't just help it and it is becoming more of a second nature to me overtime, it is probably because of my mathematics background and calculator projects I have been working on and in the past. In mathematics, extra care is needed in isolating integers and variables, so that the program will calculate based on the PEMDAS convention. Otherwise, the calculated output is inaccurate, and others will not be able to replicate it.

problem it's here

WHERE name='facebook'

diafol · Answer 7 · 2012-04-29T07:08:04+00:00

You don't need a Where clause on an insert query. It doesn't make sense to do so in your example

it's work !!!!

diafol · Answer 10 · 2012-04-29T17:41:00+00:00

Like I said WHERE clause doesn't belong in INSERT query. The WHERE clause is usually linked to SELECT, UPDATE and DELETE. As you are inserting, the WHERE clause has no meaning - not in this context anyway.
