Adding an if / missing peramiters in the cfswitch to a query statement

Hello;

I am trying to add a function to a page I made. There a lot of things, so I'll try and give you the basic function I am trying to add... and as few of the other logic as possible.

I want to add a drop down menu on this page, I have 2 querys by running. one, running the drop... Here's the code for that:

< name CFQUERY = "cata" datasource = "" #APPLICATION.dataSource # "cachedwithin =" #CreateTimeSpan (0, 6, 0, 0) # ">"
Select subName, subID
OF merchSubCat
ORDER BY subName
< / CFQUERY >

< form Name = 'box' method = "get" Action = "wallProduct.cfm? id = #subID #" >
< select name = "CategoryID" size = "1" class = "selectstyle" onChange = "category.submit (); ">
< option value = "" >--select a category--< / option >
< request CFOUTPUT = "cata" >
< option value = "#subID #" > #subName # < / option >
< / CFOUTPUT >
< / select > < / make >

OK, pretty simple. He takes the news of my db and makes a small menu out of it. Click on one of the selections, and it'll pass a url.id on the same page. This complaint is the main, that runs the page. I need to serve the first Recordset by default, and if you select in the dropdown menu, the records according to will be brough. Here's my query to add this feature.

< name cfquery = "getMerch" datasource = "#APPLICATION.dataSource #" >
MerchID SELECT, MerchName, MerchDescription, MerchPrice, MYFile, subID, CategoryID
OF goods
WHERE
< cfif isDefined ("#url.id #") >
< cfswitch expression = "#url.id #" >
< cfcase value = "1" > subID = 1 < / cfcase >
< cfcase value = "2" > subID = 2 < / cfcase >
< cfcase value = "3" > subID = 3 < / cfcase >
< / cfswitch >
< cfelse >
subID = 1
< / cfif >

< / cfquery >

When loading my page, there is no ID in the url, and my code is not like that and throwing an error as such:

Item ID is not defined in the URL.

The error occurred in C:\Websites\187914kg3\magWall\wallProduct.cfm: line 19
17 : FROM Merchandise
18 : WHERE
19 : <cfif isDefined ("#url.id#")>
20 : <cfswitch expression="#url.id#">
21 : <cfcase value="1">subID = 1</cfcase>

That's my problem, and I'm sure it's something stupid, that I forget ehre. I did this b4. How to make it work so that by default, subID = 1 appears when the page loads, and the others are displayed when you use the menu drop down.

I also talked to the other logic on this page. There is a following n button to perform this query, but also a cfswitch to invert the order of the folders, using ORDERBY in my query. But I want to get this dropdown menu to operate before adding it to this logic.

can someone help me? I have a mental block about this problem.

Thank you.

Well that really doesn't change anything.  You mix a few variables scope limited with unscoped variables earlier.  I would have just added the expanses of original code.

Speaking as to the 89 line which is a table cell (which you have...).  How did the error line related to the request code and form that you posted?

    Hello

    My phone turned off (or without service) incoming calls do not show on my list of missed calls.

    There may be a voicemail when my phone is back, but no match no missed calls.

    Is there a setting that will show you missed calls when the phone is off?

    Debra

    iPhone 6 s

    Once you turn back on your iPhone, all calls that occurred while the iPhone was off should appear in the Missed Call list.

    If they do not:

    • If you are in your area served by your cellular operator, contact your operator.
    • If you are outside this area (roaming), you can not see the calls until the return.  You could ask your cellular operator on this subject.

  • Satellite L750-1LC - Boot Manager is missing by using the recovery disk

    I bought a Toshiba satellite L750-1LC and I try to create the DVD 4 to save.

    On the first dvd that only he came an error reading twice, the other DVDs were ok.
    When I try to recover from the DVD the recovery process got stuck on the first dvd so I had to reboot and try again, but the same thing happened to it.

    After you restart the system it came a message that bootmnager is missing and windows and any other thing was gone.

    Is the promotion of "No. Matter What Guarantee" "covering this type of flaws?
    If so, what are the steps to qualify for this promotion?

    I said that I am a Romanian citizen and I have already implemented for promotion in the specified time interval.

    It seems that the first recovery disk is not created properly because you got an error message.
    As I understand your message, you have tried to boot from the first recovery disc (which was not correctly created in the past) and so the installation could not be completed successfully.

    Now, you cannot start the operating system, because the Boot Manager is missing and possibly the system is deleted also
    I see just one solution: order the new disk recovery from here and use it for the installation of the OS: http://backupmedia.toshiba.eu/landing.aspx

  • missing samples in the waveform graph

    Hello world

    When processing a file .wav into pieces, I noticed that there are missing samples on the waveform graph where two pieces must be met for the display. What could be the cause of this? Any help appreciated. Thank you!

    Milan

    Your method of reading in pieces in a for loop is create a table 1 d of waveforms with the tunnels of automatic indexation.  It is as well as what you have the data appear in different plots.  I don't know if that's what you want.

    But if this is the case, the problem is that you get to the last point of the first plot, and the first point of the next parcel is a different value.  Because they are two different plots that you do not get the line to join them, as you do between points that are part of the same plot.

  • missing events in the event log

    I'm really new and can't help otherwise explain what just happened to me. I am running Vista home and checked my reliability and performance monitor. He came back to me with missing events to the event log. 14% of my missing log files. He told me that my buffer size and maximum ETW memory buffer is not obtimal that the data sets are collected. I have AVG free virus and found no problem. I had a lot of problems with the security of the networks and curious to know for myself if someone takes information just behind my computer. Everyone acts as if I am perinoid, but I had log events while at work and shut down the system. Some are could not log on to attemtps still more successful. Many programs also show other computers on my network even glancing only ethernet to my dsl modem. So I'm not under xp but have the same diagnostic report. I would be grateful no sign, that I am not paranoid. thanx

    Hi Dancin' madman,

    Welcome to the Microsoft Vista answers Forum!

    I would like to ask you a few questions in order to get a better understanding of this issue so that we can better help you.

    (a) what version of Vista are you using?

    (b) is connected to a domain, or more than 10 computers in your computer network?

    (c) what the event log you are trying to check?

    For example, if you check the log of events for an Application, then you must

    1. click on Start, type Event Viewer in the start search and press enter

    2. in the Windows logs , select the Application, it should be under the winlogon (the last)entry. Right click on the Application and select Properties.

    3. in the Properties , you can check for the latest event logs and check the settings if it is set to replace the events, if you want, then you can change the settings.

    Because you are worried about the security of the network, you can try first run a scan of online security.

    Follow the below links for analysis online on your computer to verify if there is a malicious software on your computer.

    http://OneCare.live.com/site/en-us/default.htm

    http://www.Microsoft.com/security/malwareremove/default.aspx

    You can also check if the Services of Windows Event log and dependence are started.

    1. Click Start, type Services in start search box and press ENTER.

    2. Locate the Windows event log in the mentioned Services.

    3. check if the status is started. If the condition column is blank, right click on the Windows event log Service and select start.

    4. open the Windows Service event log, select dependencies. In dependencies, select the Windows event collector and click ok to start the service.

    5. also check the dependencies in the Windows event collector and launch service dependencies by clicking OK.

    Hope the helps of information.
