I need have the Amount field formatted like ${0,number,##,##0.00}
in the URL within outputLink. How can this be written?
<apex:outputLink value="http://www.bjp-studios.com/submit-payment/?tfa_6={!relatedTo.Amount}&tfa_13={!relatedTo.Id}">Pay Now</apex:outputLink>
Apex
controller on your page? If so you have options. NB that you should be careful about escaping output pulled in from url parameters.outputText
along withparams
? That would seem to be the only way of accomplishing what you're looking for.
