Alternating Coloring in Short View

Hi there,

I notice that under the html.pl file, in the "html_view_success" subroutine, there's this:
for (0 .. $numhits - 1) {
print "<TR><TD>";
&html_record (&array_to_hash($_, @hits));
print "</TD></TR>";
++$i;
}

And I have the short/Long display mod installed.
Can i actually write something that, let's say, have a specific color for the row (e.g. Change the above <TD> tag to <TD Bgcolor="Somecolor"> when the hit is an odd, and some other color when the hit is an even)
so that it makes an alternating color look? I don't know which variables will keep track of the Hit number and what perl function will be able to check whether that number is an odd or even.....

Thanks!

$row=0;
for (0 .. $numhits - 1) {
$row++;
print "<TR>";
if ($row == 1) {
print '<TD bgcolor="this_color">';
}
elsif ($row == 2) {
print '<TD bgcolor="that_color">';
$row=0;
}

&html_record (&array_to_hash($_, @hits));
print "</TD></TR>";
++$i;
}

Hi there, and thanks!

However, now I discovered that where changing the color of the <TD> actually has an effect is within the "html_record", not "html_view_success".

Is it possible to pass the $row variable into the "html_record" subroutine, or is there another method?

Thanks!

I don't understand what you are trying to do. You may have to draw it out for me or give me a link to an example.

These are the codes I have (with using the Compact Table View Mod from the Resource Center):

Code:
      if ( $db_total_hits == 1 ) { 
          %rec = &array_to_hash(0, @hits); 
          &html_record_long(%rec); 
          print qq| 
            <P> 
            <CENTER> 
            <$font> 
            <B><a href=\"$ENV{'HTTP_REFERER'}\">Back to Previous Page</a></B> 
          </CENTER></font>|; 
      }   
      else  { 
          &html_record_row(&array_to_hash($_, @hits)); 
          for (0 .. $numhits - 1) { 
            if ($i%2) { 
              print qq|<tr bgcolor="#DDDDDD">|; 
              } 
           else { 
              print qq|<tr bgcolor="#EEEEEE">|; 
              } 
          &html_record(&array_to_hash($_, @hits)); 
            print "</tr>"; 
          ++$i; 
          } 
          print "</TABLE></DIV></CENTER>"; 
      }

Regards.

How about for templates? I have links working to give me alternate colors using templates, but I can't seem to figure out dbman using templates.

Any ideas?
Thanks!

Re: Alternating Coloring in Short View In reply to

In the sub html_view_success routine (in the dbm_templates.pl) file, you use the same codes. But rather than using print qq|, you replace that with $variable. (Whatever $variable that TimRyan used in that sub-routine.)

So, the codes would look like the following:

Code:
      if ( $db_total_hits == 1 ) { 
          %rec = &array_to_hash(0, @hits); 
          &html_record_long(%rec); 
      }   
      else  { 
          &html_record_row(&array_to_hash($_, @hits)); 
          for (0 .. $numhits - 1) { 
            if ($i%2) { 
               $variable .= qq|<tr bgcolor="#DDDDDD">|; 
              } 
           else { 
               $variable .= qq|<tr bgcolor="#EEEEEE">|; 
              } 
          &html_record(&array_to_hash($_, @hits)); 
            $variable .= qq|</tr>|; 
          ++$i; 
          } 
            $variable .=  qq|</TABLE></DIV></CENTER>|; 
      }

Best of luck!

Good..at least you figured out what you needed to do.

You're welcome.

Re: Alternating Coloring in Short View In reply to

Thanks for the help Eliot. Here is what my final solution was. I do not have the compact forms mod installed so it's a little different.

Code:
 if ( $db_total_hits == 1 ) { 
                         %rec = &array_to_hash(0, @hits); 
			$view_success_N_html_record .= qq|<tr bgcolor="#EEEEEE">|; 
                        $view_success_N_html_record .= &html_record(%rec); 
			$view_success_N_html_record .= "</tr>"; 
                     }   
                     else  { 

                         for (0 .. $numhits - 1) { 
                           if ($i%2) { 
                     $view_success_N_html_record .= qq|<tr bgcolor="#DDDDDD">|; 
                             } 
                          else { 
                              $view_success_N_html_record .= qq|<tr bgcolor="#EEEEEE">|; 
                             } 

                          $view_success_N_html_record .= &html_record (&array_to_hash($_, @hits)); 
                           $view_success_N_html_record .= "</tr>"; 
                         ++$i; 
                         } 
			}  
                           $view_success_N_html_record .=  "</TABLE></DIV></CENTER>";
