How to execute php script using drush?

Question

I am new to Drush. How can I execute this script to remove comments of a specific user?

$uid = xx // the spam users id;
$query = db_query("SELECT cid FROM {comments} WHERE uid = %d", $uid);
while($cid = db_result($query)) {
  comment_delete($cid);
}

Also, that would be great if you could tell me how to complete the script so that it takes username instead of $uid.

Thanks

Answer 1

You can convert the script in a Drush shell script.

A drush shell script is any Unix shell script file that has its "execute" bit set (i.e., via chmod +x myscript.drush) and that begins with a specific line:

    #!/usr/bin/env drush

or

    #!/full/path/to/drush

Drush scripts are better than Bash scripts for the following reasons:

• They are written in PHP
• Drush can bootstrap the site before running the script

The following is the example you can find on helloword.script.

#!/usr/bin/env drush

//
// This example demonstrates how to write a drush
// "shebang" script.  These scripts start with the
// line "#!/usr/bin/env drush" or "#!/full/path/to/drush".
//
// See `drush topic docs-scripts` for more information.
//
drush_print("Hello world!");
drush_print();
drush_print("The arguments to this command were:");

//
// If called with --everything, use drush_get_arguments
// to print the commandline arguments.  Note that this
// call will include 'php-script' (the drush command)
// and the path to this script.
//
if (drush_get_option('everything')) {
  drush_print("  " . implode("\n  ", drush_get_arguments()));
}
//
// If --everything is not included, then use
// drush_shift to pull off the arguments one at
// a time.  drush_shift only returns the user
// commandline arguments, and does not include
// the drush command or the path to this script.
//
else {
  while ($arg = drush_shift()) {
    drush_print('  ' . $arg);
  }
}

drush_print();

 

You can made the script executable, so you can execute it with <script file> <parameters> where <script name> is the script name, and <parameters> are the parameters passed to the script; if the script is not executable, you call it with drush <script name> <parameters>.

Answer 2

With drush php-eval, you can run your script without having to save it to a file first:

drush php-eval '
  $uid = 1234; 
  $query = db_query("SELECT cid FROM {comments} WHERE uid = %d", $uid);
  while($cid = db_result($query)) {
    comment_delete($cid);
  }
'

This uses nested quotation marks, so to prevent a mess I recommend to use only double quotes " within the PHP code.

Answer 3

I think you're looking at drush -d scr --uri=example.org sample_script.php to execute sample_script.php.

Answer 4

We can use drush php-script script_name to excute php file in Drush.

For help related to Drush for executing php files Type Drush php-script --help will list you the commands

Note: I have placed php scirpt in root folder of Drupal

Answer 5

It is simple you can run a php script by drush scr ~/sample.php.

Answer 6

On your command line, from anywhere, run:

$ drush --root=/path/to/drupal-installation --uri=youdomain.com scr /path/to/your/script.php

In case you are already at /path/to/drupal-installation just run:

$ drush --uri=youdomain.com scr /path/to/your/script.php

In case you are even further ahead at /path/to/drupal-installation/sites/youdomain.com than just run:

$ drush scr /path/to/your/script.php

your script.php file:

<?php
// Not always needed but sometimes you might have to first login as an administrator.
$admin_uid = 1;
$form_state = array('uid' => $admin_uid);
user_login_submit(array(), $form_state);

// Now the logged in user global $user object become available.
global $user;
print_r($user);

// Do whatever you want here.

Answer 7

Please note that the db_result has been removed in Drupal 7. The above code can be changed to:

$result = db_query($query);
foreach($result as $cid) {
  comment_delete($cid);
}

If you want to use username instead of the uid then you can get the username using this:

$username = user_load($uid)->name;
