cfdump

[drdagwood]

I'm looking for a way to output <cfdump var="#Session.app_change_list#" label="Changes" expand="yes" > into a user friendly format for clients to see since you don't use cfdump on live sites. All this does is show what changes a user just made and is displayed right after the user makes the changes.

Thanks,
D

To clarify, what's the variable type of session.app_change_list?

If it is, as the name implies, a list, you can loop over the list and output the values:
<h3>App Changes</h3>
<cfloop list="#session.app_change_list#" index="i" delimiters=",">
#i#<br/>
</cfloop>

If it's not a list or your looking for a different approach, please post some more details.

Cheers,
Craig

Craig,
sorry I should have posted that it's a Struct type. I did try the loop you posted but recieved the following error:

Complex object types cannot be converted to simple values.
The expression has requested a variable or an intermediate expression result as a simple value, however, the result cannot be converted to a simple value. Simple values are strings, numbers, boolean values, and date/time values. Queries, arrays, and COM objects are examples of complex values.
The most likely cause of the error is that you are trying to use a complex value as a simple one. For example, you might be trying to use a query variable in a <CFIF> tag. This was possible in ColdFusion 2.0 but creates an error in later versions.


The error occurred in C:\CFusionMX7\wwwroot\ryh_dev\cfc\views\alertView.cfc: line 12

10 :
11 : <h3>App Changes</h3>
12 : <cfloop list="#session.app_change_list#" index="i" delimiters=",">
13 : #i#<br/>
14 : </cfloop>

No worries...I was only guessing list since the word list was in the variable name.

You can do the same type of thing but use a collection loop to loop over the contents of a structure. For an example, I am going to assume that your structure has a key for the type of change and then a value for the change made (might not be the case but this is just for illustrative purposes):
<h3>App Changes</h3>
<p>
<cfloop collection="#session.app_change_list#" item="key">
#key#: <!--- this outputs the name of the key itself --->
#session.app_change_list[key]#<br/><!--- this outputs the actual value of the key -->
</cfloop>
</p>

If you had only one element in your structure and it was session.app_change_list.fontSize = 12px

The (HTML) output would look like:
<h3>App Changes</h3>
<p>
fontSize: 12px;<br/>
</p>

I hope this helps!

Cheers,
Craig
