Hello,

I have this Data into my SQL Table TblDataInfo.

Example of my data:

Data_ID:                 10254
user_submitted:            1
user_date_submitted:      2013-01-4 13:10:10.707
User_Confirmation:                       DATA-16687-20120104011007
id_number:            2432
Data_year:            2011-2012


SELECT [Data_id]
      ,[user_submitted]
      ,[user_date_submitted]
      ,[user_confirmation]
      ,[id_number]
      ,[Data_year]
  FROM [ABC].[dbo].[tblDATAInfo]
  where id_number like '2432'


My Question:
------------------------

<p align="center"><a href="http://www.abc.com"><img src="mybutton.jpg" width="100" height="50" border="0"></a></p>


I would like to add a coldfusion code before the button image so that it disappears from my page, once a user has filed the data. This would involve putting some code around the button "mybutton.jpg" that would check the tblDataInfo table for the member's ID number and the Data_year=2011-2012 (in the same record), which is what gets stored in the table (along with some other info), once the member files.

Now, I have a coldfusion page who display that image button.  So I don't want to display the button every time on that page when the user logged again... because he already filled the forms.

So could you please helpm in this , what my new querry should be something like this ?

<cfquery name="DisplayButtons" datasource="ABC" username="#application.username#" password="#application.password#">
      SELECT * FROM tblDATAInfo
         WHERE (id_number = #client.user_id#) and
        (Data_Year = '2011-2012')
</cfquery>

Then my coldfusion code will be:

<cfif .....

Just check the query recordCount. If it's 0, they haven't filed yet, so show the button.


<cfif DisplayButtons.recordCount eq 0>
       show the button
</cfif>

(Also, it's a good practice to always use cfqueryparam to prevent sql injection. Edit Not sure of your data types, but something like this:  )

         SELECT id_number 
         FROM    tblDATAInfo
         WHERE id_number = <cfqueryparam value="#client.user_id#" cfsqltype="cf_sql_integer"> 
         AND   Data_Year = <cfqueryparam value="2011-2012" cfsqltype="cf_sql_varchar">

In order for the button to disappear, you would need to develop code that would check that table for the member's ID number and the 2011-2012 data in the same record, for the button to NOT display.  You need to use both fields since there is data in that table from previous years. Let me know if that's not clear.

This is what it should look like. You just need to pass in the right year. Let me know if you need help with that part.

<!--- check for existing records for year 2011-2012 --->
<cfquery name="DisplayButtons" datasource="ABC" username="#application.username#" password="#application.password#">
  SELECT id_number
         FROM    tblDATAInfo
         WHERE id_number = <cfqueryparam value="#client.user_id#" cfsqltype="cf_sql_integer">
         AND   Data_Year = <cfqueryparam value="2011-2012" cfsqltype="cf_sql_varchar">
</cfif>

<!---- If no records were found, go ahead and show the button ---->
<cfif DisplayButtons.recordCount eq 0>
    <p align="center">
     <a href="http://www.abc.com"><img src="mybutton.jpg" width="100" height="50" border="0"></a>
     </p>
</cfif>

Hello Agx,

Your code didn't work.  I did the following code and it's working.

I have a question for you, how i'm able to reverse the CFistatement

      <cfif DisplayUser.DATA_submitted eq 1>
               &nbsp;

<cfelse>
          <p align="center">
     <a href="http://www.abc.com"><img src="mybutton.jpg" width="100" height="50" border="0"></a></cfif>

Oh, I thought you wanted to display the button if the record *didn't* exist.  If it's the other way around, then your code is right.  Though to be safe you might use GTE 1. So it'll still work if there's ever more than 1 record.

Oh wait a minute ... ignore my last comment.  I see the problem. You're not using the recordCount like in my example. It should be this instead:

        <cfif DisplayButtons.recordCount eq 0>
  <p align="center">
     <a href="http://www.abc.com"><img src="mybutton.jpg" width="100" height="50" border="0"></a>
        </cfif>
