How to read input username to drush script?

Question

I need to complete a script which gets a username from terminal to a php script and then deletes the user's comments.

So I am wondering how the username should be read by the php script, the same way that one can read a value in a bash script.

Thanks

Answer 1

In your Drush command you need to call drush_get_option('myoption'); to get the value of an input parameter.

To call your Drush command you need to specify your input option as below:

drush mycommand --myoption=myvalue

Answer 2

there is an example command in the drush directory : http://drupalcode.org/project/drush.git/blob/refs/heads/7.x-4.x:/examples/sandwich.drush.inc

in the command hook you define your arguments and those are then passed to the function that implements the command

Answer 3

If you implement a drush command, you can call that via the command line and define arguments and switches.

You can easily then hook into drupal. as your function can run from a bootstrapped drupal instance.

In answer to the question by "alfish"

I think the ultimate answer to this "old" question is to use PHP to control stdin.

function ask_user_name() {
  print("Please input your name: ");

  $handle = fopen ("php://stdin","r");
  $line = fgets($handle);

  drush_print("Your name is $line");
}

Basically there was no need to establish an interface mechanism in drush since it already exists in php... but Drush does provide four commands anyway.

• drush_choice
• drush_choice_multiple
• drush_confirm
• drush_prompt

So in using drush_prompt you would do something like this.

function ask_user_name() {
  $result = drush_prompt("Please input your name",NULL,TRUE);
  drush_print("Your name is $result");
}

I hope this helps.
