PHP WebDriver cant select iframe for login

Question

I am making script that will login to "https://asia.nikkei.com/". The script opens the login window which is in a iframe.

But then iam not able to select <inputs> for email and password. And when I try to switchTo iframe with id "piano-id-AciFE", I'm getting "no such frame" error using this code:

$driver->switchTo()->frame("piano-id-AciFE");

I tried another solution with:

$username = $driver->switchTo()->activeElement();

after the login window open, but this solution doesnt work either.

Is there any way to select login input in this case?

Answer 1

The value of the id attribute is partially static (i.e. piano-id-) and partially dynamic (i.e. AciFE). When I access the website I find the value of the id attribute as piano-id-IE9ZK

In such cases to switch to the desired iframe you can refer to the preceeding(sibling) WebElement and you can use the following locator strategy:

• Using xpath and following:

  $element = $driver->findElement(WebDriverBy::xpath("//button[@aria-label='Close']//following::iframe[1]"));
  $driver->switchTo()->frame(element);
  

• Using xpath and following-sibling:

  $element = $driver->findElement(WebDriverBy::xpath("//button[@aria-label='Close']//following-sibling::iframe[1]"));
  $driver->switchTo()->frame(element);
