Perl variables not showing any values

Hi all

Small problem trying to show some values from my perl variables. Sorry if this is going over old ground from a previous thread, though tried everything and can't figure out whats wrong.

The image snippet below works, the caption and photographer part show nothing, no values.

<img src="{iw_value name='$image'/}" class="slider-image"/>

Full code

<iw_iterate var="image" list="items.gallery.images">
    <iw_perl>
      my $image           = iwpt_dcr_value('image.image');
      my $caption         = iwpt_dcr_value('image.imagecaption');
      my $photographer    = iwpt_dcr_value('image.photographer');
    </iw_perl>
    <div class="slide">
      <img src="{iw_value name='$image'/}" class="slider-image"/>
      <div class="overlay-text">
        <p>{iw_value name='$caption'/}</p>
        <p class="copyright">&copy; {iw_value name='$photographer'/}</p>
      </div>
    </div>
  </iw_iterate>

If it helps, here is my capture form code:

<!-- photo gallery/carousels -->
<container name="gallery">
  <!-- image and caption work as a group -->
  <container name="images" default="0" min="0" max='unbounded'>
    <!-- image field -->
    <item name="image" max='1' required="t">
      <label>Image (Width 500px approx)</label>
      <description>Add images for carousel gallery [jpg].</description>
      <browser initial-dir="/static/images/"
       ceiling-dir="/static/" extns=".jpg,.jpeg"
       size="50" maxlength="1000" />
    </item>
    <!-- image caption field -->
    <item name="imagecaption" max='1' required="t">
      <label>Caption (Add a generous description)</label>
      <description>Add a description about the photograph</description>
      <text size="80" maxlength="400" />
    </item>
    <!-- photogrpahers name field -->
    <item name="photogrpaher" max='1' required="t">
      <label>Photographers Name</label>
      <description>Copyright notice displays under photograph</description>
      <text size="80" maxlength="50" />
    </item>
  </container>
</container>

Can anybody see what I'm doing wrong?

Cheers, Barry

First, you should be using angle brackets <iw_value>. The curly {iw_value} syntax is meant for use only inside the attributes of other tags. Secondly, "photographer" is misspelled in your DCT.

"you should be using angle brackets <iw_value>

Thanks for the reminder, either way, if I replace imagecaption with image or photographer, the images data still shows with or without brackets.

Secondly, "photographer" is misspelled in your DCT

Nice catch, though this makes no change.

What do you think, any other suggestions?

Thanks, Barry

I can't see anything else wrong with it, so I'd have to start asking the silly questions like "are you sure your input DCR actually has values for those fields?" Smiley Happy

Good question, wasn't sure myself Smiley Happy

Here is some of the output taken from the DCR

<item name="gallery">
  <value><item name="images">
      <value>
        <item name="image"><value>/static/media/images/example_articlethumb_1.jpg</value></item>
        <item name="imagecaption"><value>The PHP development team announces availability of PHP 5.4.</value></item>
        <item name="photographer"><value>Jim</value></item>
      </value>
      <value>
        <item name="image"><value>/static/media/images/example_articlethumb_2.jpg</value></item>
        <item name="imagecaption"><value>The PHP development teams announce availability of PHP 5.5.</value></item>
        <item name="photographer"><value>Jenny</value></item>
      </value>
      <value>
        <item name="image"><value>/static/media/images/example_articlethumb_3.jpg</value></item>
        <item name="imagecaption"><value>The PHP development team announces availability of PHP 5.6.</value></item>
        <item name="photographer"><value>John</value></item>
      </value>
    </item>
  </value>
</item>

Everything looks good to me, can't see anything out of the ordinary.

What do you think?

Found it.. In the <iw_iterate>, you're declaring $image. Then your first line of PERL redefines $image, which is why the next two calls don't find any data ($image is no longer a noderef). Try changing $image to something like $imgsrc.

Catch of the year rpoulin! Smiley Happy It works! Fixed it!

Updated Version:

<iw_iterate var="imgsrc" list="items.gallery.images">
  <iw_perl>
    my $image           = iwpt_dcr_value('imgsrc.image');
    my $caption         = iwpt_dcr_value('imgsrc.imagecaption');
    my $photographer    = iwpt_dcr_value('imgsrc.photographer');
  </iw_perl>
  <div class="slide">
    <img src="{iw_value name='$image'/}" class="slider-image"/>
    <div class="overlay-text">
      <p><iw_value name='$caption'/></p>
      <p class="copyright">&copy; <iw_value name='$photographer'/></p>
    </div>
  </div>
</iw_iterate>

Thank you, Barry
