I saw a thread that discussed displaying images in place of text for links as explained by Eliot Lee.

The solution is as follows:

1) Add the following variable in your default.cfg file:
$wwwimage = qq|img src="/dir/image.gif" alt="" width="" height="" border="0"|;

2) Then in the sub html_record routine in the html.pl file, change the following codes:
<a href="$rec{'URL'}">$rec{'URL'}</a>

with the following:
<a href="$rec{'URL'}"><$wwwimage></a>

I can see how this works but how do you only display the image if no value is returned? I am pretty (actually very) new to all this and appreciate any help I get.

Thanks

I think rather than using this:

$wwwimage = qq|img src="/dir/image.gif" alt="" width="" height="" border="0"|;

It may be easier to make that:

$wwwimage = '<img src="/dir/image.gif" alt="" width="" height="" border="0">';


Then in the sub html_record routine you could just enter the variable as: $wwwimage

If you only want to print the image if there is a value you could use:

if ($rec{'URL'}) { print qq| <A HREF="$rec{'URL'}">$wwwimage</A> |; }

Be sure to close off you print statement before the line and then begin again for additional lines like this:

|;
if ($rec{'URL'}) { print qq| <A HREF="$rec{'URL'}">$wwwimage</A> |; }
print qq|

Hope this helps

You truly are a maven
Thanks It works great!
However the image appears even when the returned value null.
Any ideas why the if statement doesn't work?

Cesar, do you have a default http:// entered for the field definition? If so, you may want to change the code to something like this:

if ($rec{'URL'} gt $db_defaults{'URL'}) { ...

The rest of LoisC's code.

Cesar is the person who was looking for an answer to a question!

Personally, I like having the default http:// if for no other reason than simply to help in educating people that a complete URL includes the http://

By comparing the call to the default, the display can be controlled.

True, although LoisC's code works too. It's kinda nice to see several variations on completing the task.

Basically what I have is a value being returned that is the name of a document.
I then take this and place it within to variables that will complete the url to the document.

In default.cfg I have:

$docimage = '<img src="path/to/gif/word.gif" border="0">';


So in html_record I have:

my $docurlstart = '<a href="http://path/to/doc/dir/';
my $docurlend = '" target="_blank">';


|;
if ($rec{'docname'}) { print qq| docurlstart$rec{'docname'}$formattedend$docurlend</A> |; }
print qq|

I really didn't change much, so I can't see why it would display when nothing is returned.
Thanks

Thanks Karen that did the trick.

This is what I did for the empty fields.

if ($rec{'URL'} gt " ") { ...

A more condensed version would be:

rather than using:

my $docurlstart = '<a href="http://path/to/doc/dir/';
my $docurlend = '" target="_blank">';

is to perhaps use:

$wwwimage = '<img src="http://path/to/doc/dir/image.gif" alt="" width="" height="" border="0">';

And then for your html_record_form use:

if (length($rec{'URL'}) > 7) {
print qq|Web URL: <A HREF="$url{'URL'}" target="blank">$wwwimage</A>

What this would do is to display the image and url link only if there is more than just http:// within the field entry.
