Check if an image exist

Hi!

I have a assigned 2-6 images for a product and added custom image patterns, but as the number of images can vary I only want to display image patterns that really have an attached image. I'm defining the patterns in the product catalog module and that the product images will reside in Billeder/Products and e.g. if there's not an image 45454_Image2_Large.jpg in that folder I don't want to display that tag, now it's an empty image if the jpeg file don't exist.

Is this possible?

Best regards,
P

What version do you use?
Can you attach an image of your paragraph settings and maybe your template?

Kind regards,
Merethe

Hi!

Here is my code:

<xsl:if test="Ecom.Product.Image2Large.Clean != ''">

            <a>
              <xsl:attribute name="href">
                <xsl:value-of select="Ecom.Product.Image2Large.Clean" disable-output-escaping="yes"/>
              </xsl:attribute>

              <img
                  height="64" width="60" style="width: 60px; height: 54px; border: 0px;" >
                <xsl:attribute name="src">
                  <xsl:value-of select="Ecom.Product.Image2XSmall.Clean" disable-output-escaping="yes"/>
                </xsl:attribute>

                <xsl:attribute name="alt">
                  <xsl:value-of select="Ecom.Product.Name" disable-output-escaping="yes"/>
                </xsl:attribute>
              </img>
              
            </a>

          </xsl:if>

Hi Per!

I hope that can help you:)
In global settings you can set the img that will shown if pattern img is absent
"/Globalsettings/Ecom/Picture/NoPicture/" & Pattern
for example, in your case:
"/Globalsettings/Ecom/Picture/NoPicture/2Large" -> "Billeder/NoPicture/x.jpg"
"/Globalsettings/Ecom/Picture/NoPicture/2XSmall" -> "Billeder/NoPicture/x.jpg"
and so on...
So you can always determine is pattern img exist or not.

Best regards,
Vladimir

Hi!

But I can only find settings for the patterns Small, Medium and Large, not the patterns of my own. There is a field to type in pattern, but no place to set the image if an image with that pattern doesn't exist.

Best regards,
Per

Do you have access to GlobalSetting.asph file?
If no, let's I self create these setting for you (I need to know address)

Vladimir

I think so, I have full access to the solution, it's a custom solution. Just tell me where this file is placed.

Hi!

I found it, but still a problem, my patterns are

2XSmall
3XSmall
4XSmall
5XSmall

But it seems like starting a node with a number is not valid xml. When I added these settings, the whole admin page became white with no content.

Do you have an email?

hm.. you are right, xml node can't start with a number... this was the most right way I think...
Well... another way extend xslt with c# code... but it is better not to do so...

Hi! I think I can solve it in another way. But how do you write the xml code? I have tried this:

 <Picture>
      <NoPicture>
        <Medium>
        </Medium>
        <Large_path>
        </Large_path>
        <Large>
        </Large>
        <Small_path>
        </Small_path>
        <Medium_path>
        </Medium_path>
        <Small>
        </Small>

       
        <Img2_XSmall></Img2_XSmall>
        <Img3_XSmall></Img3_XSmall>
        <Img4_XSmall></Img4_XSmall>
        <Img5_XSmall></Img5_XSmall>

        <Img2_XSmall_path></Img2_XSmall_path>
        <Img3_XSmall_path></Img3_XSmall_path>
        <Img4_XSmall_path></Img4_XSmall_path>
        <Img5_XSmall_path></Img5_XSmall_path>
        
        </NoPicture>

As I understand you change your pattern prefix to Img2_XSmall, Img3_XSmall etc?
In that case your xml should be, for example:

<Picture>
     <NoPicture>
       <Medium>
       </Medium>
       <Large_path>
       </Large_path>
       <Large>
       </Large>
       <Small_path>
       </Small_path>
       <Medium_path>
       </Medium_path>
       <Small>
       </Small> 
       
       <Img2_XSmall>Billeder/NoPicture/x.jpg</Img2_XSmall>
       <Img3_XSmall>Billeder/NoPicture/x.jpg</Img3_XSmall>
       <Img4_XSmall>Billeder/NoPicture/x.jpg</Img4_XSmall>
       <Img5_XSmall>Billeder/NoPicture/x.jpg</Img5_XSmall>
        
       </NoPicture>

ps: don't forget to create this picture of course: /Files/Billeder/NoPicture/x.jpg

Hi!

I'm not getting this to work, any ideas how to write? I asked the support too, but they referred me back to the forum because it was a developer issue. The solution is viking.net.

Best regards,

Hi Per!
No no, I talked about the values in left column - so to write them in GlobalSettings they should be started with letters like (Img2_XSmall, Img3_XSmall etx)

Best regards,
Vladimir

Hi again!

Yes I know, I've tried this and many other variants, but for some reason I can't make it work. No matter how I write I only get the path to the non existent pattern image file. I've looked in the template xml output and the a path to the "no-image"-file is missing.

Can you please take a look in the solution to see what's wrong, I gave you the solution name in a previous forum post.

If you do this

Best regards,
Per

Per, I open viking.net - but this is just static html page?

Oh, sorry, I meant viking.net.dynamicweb.se. Can you go to admin and check?

Best regards,

Hi Per,
it seems I found decision
1) paths in globalsetting should be without /files/, just: Billeder/no-image.gif
2) tags for this case should be ended with .Default.Clean postfix (instead of .Clean)

Best regards,
Vladimir
