[d.r.l]

Hey Kovid, always a pleasure to see you personally helping out, it's very impressive. Thanks!

Your input helped out and I could move to steps forward. I am now stuck at the login page. I had to put back the 'open the login page first' before moving forward with the downloading of the code itself.

I'm now stuck with the login itself, I have the following error messages

mechanize._mechanize.FormNotFoundError: no form matching name 'login'

referring to the page's source code, I've tried to use the following tags (in red):

<div class="entry-content">
        <div class="login-form-container">
	
	<form name="loginform" id="loginform" action="https://skepticalinquirer.org/wp-login.php" method="post">
			
			<p class="login-username">
				<label for="user_login">Email or Username</label>
				<input type="text" name="log" id="user_login" class="input" value="" size="20">
			</p>
			<p class="login-password">
				<label for="user_pass">Password</label>
				<input type="password" name="pwd" id="user_pass" class="input" value="" size="20">
			</p>

While writing this, I changed used the name of the form itself loginform

And now have the following error message:

mechanize._form_controls.ControlNotFoundError: no control matching name 'EMAILADDRESS'

Here's the updated code as it stands now

import re, zipfile, os
from calibre.ptempfile import PersistentTemporaryDirectory
from calibre.ptempfile import PersistentTemporaryFile
from urllib.parse import urlparse, urlsplit

class TheSkepticalInquirer(BasicNewsRecipe):
    title = u'The Skeptical Inquirer'
    description = 'Investigation of fringe science and paranormal claims.'
    language = 'en' 
    needs_subscription = True 

    def build_index(self):
        br = self.get_browser()
        if self.username is not None and self.password is not None:
            br.open('https://skepticalinquirer.org/member-login/')
            br.select_form(name='loginform')
            br['HIDDEN']   = self.username
            br['HIDDEN'] = self.password
            br.submit()
        return br

        pdflink = br.find_link(text_regex=re.compile('https://skepticalinquirer.org/archive/'))

        # Cheat calibre's recipe method, as in post from Starsom17
        self.report_progress(0,_('downloading PDF'))
        response = br.follow_link(pdflink)
        dir = PersistentTemporaryDirectory()
        pdf_file = PersistentTemporaryFile(suffix='.pdf',dir=dir)
        pdf_file.write(response.read())
        pdf_file.close()

        # Get all formats into Calibre's database as one single book entry
        self.report_progress(0.6,_('Adding files to Calibre db'))
        cmd = "calibredb add -1 " + dir
        os.system(cmd)

        return index

Thanks again for your assistance, here !
