Hi,
I'm new to using session variables and don't quite understand the "locking"
thing. What'll happen if you don't lock everything?
Here is some code that I've been using. I used <cflock> when I created the
array but not when I'm reading or writing. It's been working fine. Am I in
for big bad application explosion?
How would you lock the code below?
Thanks,
Eric Homa
<CFLOCK TIMEOUT="30" THROWONTIMEOUT="Yes">
<cfif NOT IsDefined("session.basket")>
<cfset session.basket = ArrayNew(2)>
</cfif>
</CFLOCK>
<cfset FoundInBasket = 0>
<!--- Case 1 - Item already exists in basket - add qty --->
<cfif ArrayLen(session.basket) NEQ 0>
<cfloop from="1" to="#ArrayLen(session.basket)#" index="LoopCount">
<cfif session.basket[LoopCount][1] EQ "#Form.ModelNumber#">
<cfset session.basket[LoopCount][3] =
session.basket[LoopCount][3]+#Form.AddQty#>
<cfset FoundInBasket = 1>
</cfif>
</cfloop>
</cfif>
<cfif NOT FoundInBasket>
<cfset session.basket[ArrayLen(session.basket)+1][1]=#Form.ModelNumber#>
<cfset session.basket[ArrayLen(session.basket)][2]=#Form.SalePrice#>
<cfset session.basket[ArrayLen(session.basket)][3]=#Form.AddQty#>
</cfif>
