So, I have a page where folks are submitting shipment info and getting a
label back to the browser in pdf format using cfcontent, cfheader in a
separate page called getLabels.cfm. All the shipment processing is Ajaxy
and wonderful, and at the end a bit of javascript says...
window.location.replace("/pathTo/getShippingLabel.cfm?invoice="+o.invoice);
Simple and easy, normal stuff, been there, done that a million times..
<cfheader name="Content-Disposition" value="attachment;
filename=labels-#url.invoice#.pdf">
<cfcontent type="application/unknown"
file="#application.props.getproperty("labelsPath","")##url.invoice#.pdf">
So, here is the brain teaser. (and yeah, I left all the other code out)
When the label pdf doesn't exist, how to I stop the original calling page
from going to getLabels.cfm and displaying "File not found" message? I
want the user to stay on the page they are working in.
Instead I would like to do this in getLabels.cfm
<cfif not
fileexists("#application.props.getproperty("labelsPath","")##url.invoice#.pdf")>
Do something magic and abort the request so the page doesn't change
<cfelse>
<cfheader name="Content-Disposition" value="attachment;
filename=labels-#url.invoice#.pdf">
<cfcontent type="application/unknown"
file="#application.props.getproperty("labelsPath","")##url.invoice#.pdf">
</cfif>
in 20 years of CF, I have never tried this...
