Re: [ACFUG Discuss] Alternate image shown logic help?

Java?  Clearly there is no Java there.  A dead giveaway is this line
  if( Len(objProduct.getImage2()) GT 0 ) 
No respectable language like Java uses GT! haha!  j/k

This is cfscript.

Good stuff all of you.

However if I want to put 3 steps in there the middle step would be

<cfelseif> correct?

 

I am also a little uneasy about what seems like multiple languages.

It seems that the orgininal code is in Java (?).

 

How will I imbed the CF into that language?

 

Ex:

<!--- Does the file exist on the server's file system? --->

<cfif FileExists("C:\www\images\picture.gif")>


    <!--- The file does exist, so let's show the picture ---->

    <img src="">
<cfelseif> <!---is this right???--à

   
    <!--- The file does not exist, let me show you an alternate picture that says that no image was available --->
   
    <img src="">

 

<cfelse>
   
    <!--- The file does not exist, let me show you an text that says that no image was available --->


   
            writeoutput("<img src=''>");
</cfif>

Robert,
Chris has it right with using the FileExists function.  Here is a definition of the usage of the function: http://techfeed.net/cfQuickDocs/?FileExists

Let's look at what Chris was was demonstrating:

<!--- Does the file exist on the server's file system? --->

<cfif FileExists("C:\www\images\picture.gif")>


    <!--- The file does exist, so let's show the picture ---->

    <img src="">
<cfelse>
   
    <!--- The file does not exist, let me show you an alternate picture that says that no image was available --->
   
    <img src="">
</cfif>


Now you can display whatever you want when a file does not exist, but the FileExists function can save you some code and make your code more legible.

Also I am not quite clear.

If I am reading this right the logic should break down like this:

*************
<!---If image is listed and exists--->
        if ( intImagePos EQ 3 ){
        WriteOutput("<td class=""ProductImage"">" & Chr(10) & Chr(13));
        //'show image
        if( Len(objProduct.getImage2()) GT 0 ){
        writeoutput("<img src="" & objProduct.getImage2() & """ " &
        objProduct.getImage2Params() & ">");
<!---If image is listed and does not exist--->
        ?????????????
<!---If image does not exist--->
        }else{
        writeoutput("<p>No Picture Available</p>"); }
        WriteOutput("</td>");
*************

Or are you saying that this should be structured a different way.
Excuse my ignorance as I am a total newbie and this is my first real attempt
at logic manipulation.

Can you explain further?

You can use FileExists(absolute_path) in an if statement.

Eg.
<cfif FileExists("C:\www\images\picture.gif")>
        <img src=""> <cfelse>
        <img src=""> </cfif>

Is there a way to have an alternate image called if an image called does
not exist?

For example:
We call out the image path for the image as if it would one day be
there.
When we shoot an image as it comes into inventory we place the image in
the correct directory, and name it the part number.jpg.

We would like to have a default image show if the correct image does not
exist.

Using the string:
******************
//'display the right product image
        if ( intImagePos EQ 3 ){
        WriteOutput("<td class=""ProductImage"">" & Chr(10) & Chr(13));
        //'show image
        if( Len(objProduct.getImage2()) GT 0 ){
        writeoutput("<img src="" & objProduct.getImage2() & """ " &
objProduct.getImage2Params () & ">");
        }else{
        writeoutput("<p>No Picture Available</p>"); }
        WriteOutput("</td>");
*******************
How would you modify this to be able to do that?

I can see that it would be easy to change
        }else{
        writeoutput("<p>No Picture Available</p>"); to show a path name
but it is VERY easy to add the file name even if it does not exist up
front.

Im thinking that instead of changing
        }else{
        writeoutput("<p>No Picture Available</p>"); I should use elseif
logic (hmm this is not even CF is it?) To say if the pic is not
available then call a certain image.
If that is not there then do
        }else{
        writeoutput("<p>No Picture Available</p>");
