Truncating an URL from a Browse field

gsal

Hello everyone,

I'm encountering a challenge with my template. In my datacapture.cfg I have a browse field called 'header'. It directs users to an image folder where they can choose an image. The url comes back as '/includesroot/images/myimage.gif'.

I sandwich this url into an image tag in my TPL using the <iw_value name="dcr.header"/> markup. However my web server's virtual mapping ignores /includesroot all together and expects the images folder to begin at the root: '/images/myimage.gif'.

How do I truncate the url so that the page is generated with '/images/myimage.gif' and not '/includesroot/images/myimage.gif'.

Use something like this to get the value of the field in an <iw_perl> block

<iw_perl>
$header = iwpt_dcr_value('dcr.header');
$header =~ s|includesroot||;
iwpt_output('<img src="bla/bla/$header">');
</iw_perl>

Try something like that.

Based on what you gave me, I got this to work:

<iw_perl>
<![CDATA[
$url = iwpt_dcr_value('dcr.header');
$url =~ s/\/includesroot//;
iwpt_output($url);
]]>
</iw_perl>

Thanks!

On a further note, is there another solution that will truncate the url at the datacapture.cfg file?

One way you would be able to truncate at the datacapture side is if you use your own browser callout, so then you can truncate before the value is returned to the DCT.

Another way would be to change it using FormAPI and maybe the onSave event to change the value just before the DCT is saved.

Have a look at your FormAPI docs at iw-home\httpd\iw\help\tst\formapi\index.html
