Call to undefined function form()?

PHP
1

Hi,

I have the following code however the form(‘reset-password’, part creates an error. Call to undefined function form()

I have looked up was this error is and the only suggestions I can find is that it is returned due to a spelling error. However I cant see any spelling errors. Does anyone have any suggestions on how I can fix this please?

    /// URL is defined as the root of the URL used in the email, in this example it would be "http://example.com/"
    URL . "resetpassword.php?page=reset-password" . urlencode($userid) . "&key=" . urlencode($key) . "\\r\
" .
    "\\r\
" .
    "Kind regards,\\r\
" .
    "\\r\
" .
    "The example.com Web Site"
  );
}

// form, input_hidden, table, tr, td, label, input_password and input_submit are my own wrappers which return the appropriate HTML with escaped values where required.
echo
  form('reset-password',
    input_hidden('userid', $_GET['userid']) .
    input_hidden('key', $_GET['key']) .
    table(
      tr(
        td(label('New Password')) .
        td(input_password('new_password', ''))
      ) .
      tr(
        td(label('Confirm Password')) .
        td(input_password('confirm_password', ''))
      )
    ) .
    input_submit('ok', 'OK')
  );

Is this part of a framework? Are you trying to echo form( out to the browser?

If so you are missing the quotes around your string, or you can use HEREDOC and do something like so

echo <<<FORM_OUTPUT
  form('reset-password',
    input_hidden('userid', $_GET['userid']) .
    input_hidden('key', $_GET['key']) .
    table(
      tr(
        td(label('New Password')) .
        td(input_password('new_password', ''))
      ) .
      tr(
        td(label('Confirm Password')) .
        td(input_password('confirm_password', ''))
      )
    ) .
    input_submit('ok', 'OK')
  );
FORM_OUTPUT;

Its for a password reset script which sends an email an echoes a link.

I haven’t used HEREDOC before. How do I add quotes to the string?

Sounds as if include files have not been included.

Just depends on if this is for a Client UI framework or a backend framework, do you need to include other files (as @Cups ; suggested)?
If you do, you can ignore my comment, as it would no longer apply.

If you do need it for a Client UI framework, you can either use the HEREDOC statement I posted earlier, or you can put the Client UI code in quotes like so

echo "
  form('reset-password',
    input_hidden('userid', $_GET['userid']) .
    input_hidden('key', $_GET['key']) .
    table(
      tr(
        td(label('New Password')) .
        td(input_password('new_password', ''))
      ) .
      tr(
        td(label('Confirm Password')) .
        td(input_password('confirm_password', ''))
      )
    ) .
    input_submit('ok', 'OK')
  )";

I tried both the quotes and HEREDOC and couldn’t get either to work.

This is the error Call to undefined function form() do I need to isolate the form in some way?

// $userid must be an integer that matches a valid user's ID.
function reset_password($userid) {
  query("delete from reset_password where userid = $userid");
  $key = substr(base64_encode(crypt('', '')), 0, 32);
  query("insert into reset_password values ($userid, '$key', " . time() . ")");
  // fetch is my own wrapper function to fetch a row from the query.
  $f = fetch(query("select username from organisermembers where id = $userid"));
  // smtp is my own function, you will probably want to use the php mail function.
  smtp(
    "do-not-reply@example.com", // sender

Are you using a php framework or something else. If you are using only core php then tell me, I will give you exact code.

Hi Blogaddition,

Its core PHP, Im trying to keep it as simple as possible as I am not that expierienced with PHP.

Bottom line is, there is no function named “form” defined. Where is that function defined? If it’s in a different file, you have to include that file.

In your last piece of code posted, I see the function reset_password is defined. Somewhere you need functions named

form
input_hidden
tr
td
input_submit
input_password
label

Or are those supposed to be javascript functions?
