Re: perl, DBI and CGI checkboxes

hi, If I understand you correctly you want to read the table headers of a table in the DB (or even describe the table ;) into an array and for every entry in the array add a checkbox, then on reading if that entry is checked you wish to use the associated field in the SELECT statement?

That is a spec in itself, in CGI you can use a checkbox_group as follows

print
checkbox_group(-name=>'fields_to_search',
               -values=>\@cols # Your array above
              );

And when processing

@fields_to_search=param('fields_to_search');

print "Good ",qw(night morning afternoon evening)[(localtime)[2]/6]," fellow monks."

Thanks a lot for the answer, it did work Now I want to change the script so instead of selecting the columns, selecting the rows so my script looks as follows: #!/usr/bin/perl use DBI; use CGI ':standard'; use strict; use warnings; my $q= CGI->new(); print header, start_html('Advanced Search'); # Connect to the database # See footnote 1 my $dbh = DBI->connect('DBI:mysql:mirnas', 'root', 'pass') or die "Couldn't open database: $DBI::errstr; stopped"; # Getting all the column names and creating checkboxes for them my $table = '07_11_09'; my $sth = $dbh->prepare("SELECT * FROM $table;"); $sth->execute; my @cols = @{$sth->{NAME}}; # or NAME_lc if needed $sth->finish; #printing the checkboxes print checkbox_group(-name=>'fields_to_search', -values=>\@cols # Your array above ); #storing the parameters from the checkboxes my @fields_to_search=param('fields_to_search'); #creating the submit boxes print'<FORM ACTION="http://sirocco/cgi-bin/advanced_search.pl" METHOD="POST">'; print br, '<INPUT TYPE = "SUBMIT"VALUE="Click To Submit">'; print '<INPUT TYPE="RESET"VALUE=Clear>'; print '</FORM>', end_html; [download] But when I do that I don't get anything. Also how do I pass the @params to an sql statement Would it be something like my $sth = $dbh->prepare("SELECT * FROM $table WHERE tissue = @fields to search;"); THanks for any possibble answers in advance	[reply] [d/l]

#!/usr/bin/perl

use strict; use warnings;

my $q= CGI->new();

print header, start_html('Advanced Search');

# Connect to the database
# See footnote 1
my $dbh = DBI->connect('DBI:mysql:mirnas', 'root', 'pass')
    or die "Couldn't open database: $DBI::errstr; stopped";
    
    
# Getting all the column names and creating checkboxes for them
my $table = '07_11_09';
my $sth = $dbh->prepare("SELECT * FROM $table;");
$sth->execute;
my @cols = @{$sth->{NAME}}; # or NAME_lc if needed
$sth->finish;

#printing the checkboxes
print
checkbox_group(-name=>'fields_to_search',
               -values=>\@cols # Your array above
              );
#storing the parameters from the checkboxes
my @fields_to_search=param('fields_to_search');



#creating the submit boxes
