outputting an array 1

[daNewfie]

Im using the following code to output an array on the same page the array is populated.

I am having trouble (ie its not working) on subsequent pages

<cfoutput query="qInfo">
  <cfif (form["selection_" & groupID] eq productID)>
    <cfset session.arrCustomized[1] = #productCode#> 
	#session.arrCustomized[1]#
  </cfif> 
  
</cfoutput>

hi daNewfie,

Does nothing show up on subsequent pages or just the first index in the array?

I'm not sure what it is that you are accomplish, but it lookslike you are only populating the first index of your array, try the following:

<cfoutput query="qInfo">
  <cfif (form["selection_" & groupID] eq productID)>
    <cfset session.arrCustomized[currentRow] = #productCode#>
    #session.arrCustomized[currentRow]#
  </cfif>  
</cfoutput>

hope this helps,

Actually, you code and my code produce the same results..

the problem is I did a query and I use that query in the output of the array, how fo I access the info inside the array now on a page without that query

<cfoutput>
  <cfif (form["selection_" & groupID] eq productID)>
    <cfset session.arrCustomized[currentRow] = #productCode#>
    #session.arrCustomized[currentRow]#
  </cfif>  
</cfoutput>

for instance by taking the query statemnet out of the cfoutput tag

daNewfie,

You want to know how to loop through the array and output the results without having to use the 'query object' within <cfoutput>?

  <!--- Copy your session array to a local scope --->
  <cflock scope="session" type="readOnly" timeout="10">
       <cfset myArray = duplicate(session.arrCustomized)>
  </cflock>

  <!--- Loop through the array and output the results --->
  <cfoutput>
  <cfloop from="1" to="#arraylen(myArray)#" index="i">
     #myArray[i]#
  </cfloop>
  </cfoutput>

I hope this helps,

This is what Im getting now..I search on the net and cant find anything on it

Error Diagnostic Information

An error occurred while evaluating the expression:


#myArray#


Error near line 235, column 14.
--------------------------------------------------------------------------------

The element at position 3 in dimension 1 of object "myArray" cannot be found. The object has elements in positions 1 through 30. Please, modify the index expression.


The error occurred while processing an element with a general identifier of (#myArray#), occupying document position (235:6) to (235:17).



BTW, thanks for all your help

Hi daNewfie,

It looks like I skewed my logic a little. I noticed that when we are setting the indexes of the array with values, not every index of the array is being populated. The <cfif ..> statement is selectively assigning which indexes receive values. Since 'currentRow' is updated on each iteration of the loop, the iterations that did not meet our condition did not have the corresponding index in the array populated. That is why you were receiving an error when you were trying to output the value at index 3, becasue the 3rd iteration of our loop did not meet the condition and was being skipped. Replace your array assignment code with the following:

 <cfset indexcount = 1> 
 <cfoutput query="qInfo">
    <cfif (form["selection_" & groupID] eq productID)>
      <cfset session.arrCustomized[indexcount] = productCode>
      <cfset indexcount = indexcount + 1>
    </cfif>  
</cfoutput>

Hope this helps,

jalpino

this is the code

<cfset indexcount = 1> 
 <cfoutput query="qInfo">
    <cfif (form["selection_" & groupID] eq productID)>
      <cfset session.arrCustomized[indexcount] = productCode>
      <cfset indexcount = indexcount + 1>
    </cfif>  
</cfoutput>

  <cflock scope="session" type="readOnly" timeout="10">
       <cfset myArray = duplicate(session.arrCustomized)>
  </cflock>
 
  <cfoutput>
  <cfloop from="1" to="#arraylen(myArray)#" index="i">
     #myArray[i]#
  </cfloop>
  </cfoutput>

Never mind...I got it..thanks anyway

Im not 100% sure....

all I did was kill the browser and went back in and it worked...so I think that the session variables were compounding....
