Text Fields

• A text field allows the user to enter a line of text.
• Use the text "area" construct, as opposed to this text "field" construct to allow the user to enter paragraphs.
• The Perl CGI construct to create a text field would be as follows:
  

  # Generate a text field for data entry
  print $query->h1('Please enter some text');
  print $query->textfield({-name=>'TextfieldOne',
  			 -default=>'Enter your text here',
  			 -size=>50,
  			 -maxlength=>100});
  

• The Perl CGI construct to then later extract the contents of this field would be
  

  # Extract out whatever the contents of our text field were.
  my $textInput = $query->param(-name=>'TextfieldOne');
  
  # Generate our output
  print $query->p('The text you previously entered was:'), $query->br();
  print $query->em({-align=>'center'}, $textInput);
