Hi Experts, i am using Ray's Tag for fetching Contacts From my Gmail Account. Althouh it fetched correctly and showed in a cfdump var which have structs and arrays inside that. so i am really confused how to use that.

i will attached the list here how the results are coing. just show me a way how can i use them in real code like:

display a checkbox against each email address.

the code is below:


<cfapplication name="gContacts">
 
<cfset url.reinit = 1>	
<cfif not structKeyExists(application, "gContacts") or structKeyExists(url, "reinit")>
	<cfset application.gContacts = createObject("component", "#request.cfcPath#.GoogleContacts").init("cool@gmail.com","cool")>
</cfif>
 
<cfset contacts = application.gContacts.getContacts()>
<cfdump var="#contacts#" label="Contacts" expand="true">	
 
the file is attached.

You have an array with structures in it. Each structure has elements...some are text/numbers and others are arrays or more structures. Thinking along those lines, you could access items like this:

<cfoutput>
Record 1:<br>
Email Address 1: #Contacts.Contacts[1].EMAIL.Contacts[1].ADDRESS#<br>
ID: #Contacts.Contacts[1].ID#
</cfoutput>

Sorry if that's not entirely correct...I can't the entire structure and it is large and multi-layered. If you follow that logic, you should be able to narrow down the exact way to access each item.

You will probably need to loop through each array, so it gets mroe complicated but take it one stap at a time and it's not too bad.

It should work fine (barring anything I couldn't see in the image or a brain fart). To get all the email addresses per user, you will have to use an outer and an inner loop. First cfloop the Contacts.Contacts to get the email addresses for each user. Within that loop, cfloop the inner Contacts structure to get each email address for the user.

Hmm....maybe I missed a structure. I would suggest avoiding having the same name used over and over whenever possible as it creates confusion. Try the code below. If that doesn't work, just cfdump each outer element until you get the exact syntax to reach the email field.
<cfoutput>
Record 1:<br>
Email Address 1: #Contacts.Contacts[1].EMAIL[1].ADDRESS#<br>
ID: #Contacts.Contacts[1].ID#
</cfoutput>

cool, it works but it outputs only one record, i have 25 contacts in my gmail it shows only single one, i did something like this:


<input id="gwProxy" type="hidden"><!--Session data--><input onclick="jsCall();" id="jsProxy" type="hidden">
<cfset contacts = application.gContacts.getContacts()>
<cfloop query="contacts">
<cfoutput>
#Contacts.Contacts[1].EMAIL[1].ADDRESS#<br>
</cfoutput>
</cfloop>
 
it errors out as:
 
Attribute validation error for tag cfloop.  
The value of the attribute query, which is currently contacts, is invalid.  
  
The error occurred in C:\Inetpub\wwwroot\ibestcity\google.cfm: line 13
 
11 : 
12 : <cfset contacts = application.gContacts.getContacts()>
13 : <cfloop query="contacts">
14 : <cfoutput>
15 : #Contacts.Contacts[1].EMAIL[1].ADDRESS#<br>

Right. That was just to show how it's done. You need to loop over the array. Your code is trying to loop over a query. basically, you need to loop over Contacts.Contacts. Within that, you need to loop over EMAIL. Below is Coldfusion MX code to do this. Coldfusion 8 supports an array option for cfloop but I don't know what version you are using so I didn't use it.

This was made off-hand, so don;t be surprised if there's a typo somewhere.
<cfoutput>
  <cfloop index="i" from="1" to="#ArrayLen(Contacts.Contacts)#">
    <cfloop index="j" from="1" to="#ArrayLen(Contacts.Contacts[i].EMAIL)#">
      <div>Email: #Contacts.Contacts[i].EMAIL[j].ADDRESS#</div>
    </cfloop>
  </cfloop>
</cfoutput>

Here the checkboxes:
<form>
<cfoutput>
<cfloop array="#contacts.contacts#" index="contact" >
  <cfif contact.title EQ "" >
    <cfset contact.title = contact.email[1].address >
  </cfif>
  <input type="checkbox" name="contact_id#contact.id#" id="contact_id#contact.id#" value="#contact.email[1].address#" > <label for="contact_id#contact.id#" >#contact.title#</label> <br>
</cfloop>
</cfoutput>
<input type="submit" >
</form>
