www::mechanize matchup.io form and clicking

rocteur has asked for the wisdom of the Perl Monks concerning the following question:

I'm only learning to use www::mechanize and I've had some luck but now I'm stuck and frustrated with this one.

Trying to login to matchup.io, so I ran mech-dump -forms https://matchup.io/users/sign_in


POST https://matchup.io/users/sign_in
  utf8=&#10003;                         (hidden readonly)
  authenticity_token=diJec2QOaXyKKSFfemWgQhfJo1Y9zIPg2PyiF9oajMK/JlmhI
+g7HOQvuy3BlVMx0jUvZIX8xeh5kNbDm+MqCLA== (hidden readonly)
  user[remember_me]=1            (hidden readonly)
  user[email]=                   (email)
  user[password]=                (password)
  button=<UNDEF>                 (submit)
[download]

I've not had a mixture of fields and button but to make it worse, the brackets in the fields, see user email and password aboveand they give me all sorts of errors whatever I try.

Does anyone have any idea how to prepare the fields with brackets and then the button..

Thanks in advance.

Oh, it's my first post here so accept my apologies if I'm doing something wrong in the post

Welcome to the monastery, rocteur. they give me all sorts of errors whatever I try If you perform an action which results in an error and seek some help to avoid producing the error it is usually a good idea to tell the potential helpers what the exact error message was and what the exact code was which you executed to cause it. Without that information the potential helpers could spend a lifetime guessing and guessing and guessing what the underlying problem might be. Are you familiar with the SSCCE concept? If you can provide one of those the monks will be more inclined to help you in your quest.	[reply]

The point I was trying to make is that the form items that need to be posted contain square brackets `user[email]= (email) user[password]= (password)` [download] I imagined people in this group who know www::mechanize would see the issue help me understand how to pass this to the from as the obvious way to me does not work As I said I'm only just learning www::mechanize and whilst searching for help I saw people write that members of this site know www;:mechznize.. `$agent->submit_form( form_number => 1, fields => { user[email] => $login, user[password] => $passwor +d }, );` [download] syntax error at ./mechaM.pl line 20, near "user[" Execution of ./mechaM.pl aborted due to compilation errors.

I'm not sure it solves your problem, but to create a hash with the keys specified in Perl, you have to quote the keys, as they aren't simple barewords: `fields => { 'user[email]' => $login, 'user[password]' => $pas +sword },` [download] See perlop for details: The => operator is a synonym for the comma except that it causes a word on its left to be interpreted as a string if it begins with a letter or underscore and is composed only of letters, digits and underscores. لսႽ† ᥲᥒ⚪⟊Ⴙᘓᖇ Ꮅᘓᖇ⎱ Ⴙᥲ𝇋ƙᘓᖇ	[reply] [d/l]

If this is "the point that you are trying to make," then be sure to make that clearly. Emphasize it. When your question is clear and direct, an answer follows quickly. If not, confusion and requests for clarification.	[reply]
