是否可以将URL中的ID的segment（3）更改为随机字符串（Codeigniter）？

Question

I tried to change the $config['url_suffix'](that is located at my config/config) into $config['url_suffix'] = ''; . I encountered an error, it says that "Access forbidden! You don't have permission to access the requested object. It is either read-protected or not readable by the server.

If you think this is a server error, please contact the webmaster." And I also tried to put the random_string in my view, may update is not working now

Config file

$config['url_suffix'] = '<?= random_string(40?>';

View

<a data-toggle="modal" class="btn btn-warning" data-target="#update_account-<?= $profileAccount->id?>"><span class="glyphicon glyphicon-edit"></span>Edit</a>
    <div class="modal fade" id="update_account-<?= $profileAccount->id?>" tabindex="-1" role="dialog" aria-labelledby="titleLabel">

Answer 1

Your config has missing character the closing parenthesis )

change this

$config['url_suffix'] = '<?= random_string(40?>';

to

$config['url_suffix'] = '<?= random_string(40)?>';

If not working I think your random_string function has an error
