Show only first image from multi-value imagefield (or "group multiple values")

1) #788548: Limiting output from pictures field?
2) You can place 2 fields next to eachother with css - you can add styles in the 'styles' screen en select the class in the fields overview screen.

That code snippet is for using in a custom module, not pasting them into the custom formatters as a snippet, you'd only need this bit:

  static $images = array();

  $nid = $element['#node']->nid;

  // Stop after the first one.
  if (isset($images[$nid])) {
    return;
  }

  if (empty($element['#item']['fid'])) {
    return '';
  }
  $images[$nid] = TRUE;

  $item = $element['#item'];

  $alt = isset($item['data']['alt']) ? $item['data']['alt'] : '';
  $title = isset($item['data']['title']) ? $item['data']['title'] : NULL;

  // Not sure, if you have to return here, could be 'echo' too, so choose one or the other.
  return theme('imagecache', 'uc_category', $item['filepath'], $alt, $title);
  //echo theme('imagecache', 'uc_category', $item['filepath'], $alt, $title);

There is a fix and a patch for that at #794908: When not using friendly names in styles, you get an illegal choice message.

This works fine when using custom_formatters module - Use the advanced editor, enter filefield as fieldtypes and toggle the 'handle' multiple values' checkbox.

$i = 0;
$output = '';
foreach (element_children($element) as $key) {
  if ($i < 1) {
    $item = $element[$key]['#item'];
    if (empty($item['filepath'])) {
      continue;
    }
    $i++;
    $alt = isset($item['data']['alt']) ? $item['data']['alt'] : '';
    $title = isset($item['data']['title']) ? $item['data']['title'] : NULL;
    $output .= theme('imagecache', 'IMAGECACHE_PRESET', $item['filepath'], $alt, $title);
  }
}
return $output;

Well for #9 1 and 2: The title displays are theming functions from nd, so you can override them with phptemplate in your template.php of your theme - you can remove the paragraph titles there and use a truncate function - http://api.drupal.org/api/function/truncate_utf8/6

// truncate can happen with truncate_utf8
// Not linked.
function phptemplate_nd_title_p_nolink($field) {
  return '<p>'. check_plain($field['object']->title) .'</p>';
}

// Linked.
function phptemplate_nd_title_p_link($field) {
  return '<p>'. l($field['object']->title, 'node/'. $field['object']->nid) .'</p>';
} 

For 3 (label price): that's coming from ubercart from the theme_uc_product_price() function which is very complicated. I'm not an ubercart expert, but i'd almost think that there is an option in ubercart itself to remove that label.

You were using a parameter to much:

function phptemplate_nd_title_p_link($field) {
  return l(truncate_utf8($field['object']->title, 20, TRUE, TRUE), 'node/'. $field['object']->nid);
}

As for displaying fields on two lines, those classes/styles should like define a 'float: left' (or something like that) in your CSS - I'm not *that* good in styling, I have themers for that at work :)

Yep, you can:

function phptemplate_nd_title_p_link($field) {
  $type = $field['object']->type;
  if ($type == 'product') {
    return l(truncate_utf8($field['object']->title, 20, TRUE, TRUE), 'node/'. $field['object']->nid);
  }
  else {
    // Default theming function.
    return '<p>'. l($field['object']->title, 'node/'. $field['object']->nid) .'</p>';
  }
}

Does anyone have a summary of the steps to display a single image on the search page? I'm not clear on where to start. Thanks

to ask an obvious question, so this is saying that this code depends on also using the custom-formatters module and to put this code in there?

There's no solution in creating a custom field from within ds/nd itself?

I just want to express my appreciation for the code snippet in #8.

Thanks! :)

just a couple further instructions for #8:

1. edit the 'IMAGECACHE_PRESET' from the code above on the line starting "$output" to correspond to the particular imagecache preset that you want show (othewise you'll get the broken image sign)

2. in the manage fields/build mode interface, click 'change settings' for the image and change the 'feild format' to 'Custom:your_named_field'

I follow the instruction from #8 and #21, however, I can't make the first image to be displayed in teaser view for custom_formatter 1.5 beta4. No picture was shown after the setting.
It can work with custom_formatter 1.4.
Can anyone give me some hints?!
Thanks!

#22 Can you post your snippet?

Have you entered 'filefield' as fieldtypes and did you toggle the 'handle multiple values' checkbox?

It's also always helpful if you start out with looking into everything that's in the $element array, using <?php print dsm($element); ?> (enable Devel for this)

@Swentel,

I apologize in advance for my lack of PHP skills so it could be something very simple in my code.

I have looked at your post and further instructions below and followed all steps regarding the Custom formatters module.

1. I used advanced editor mode
2. Selected the Handle multiple values
3. Pasted the code into the php area
4. Went back to the display suite build mode and selected the custom field type.

It looks like where I am messing something up is in the "imagecache preset name". I understand that I am supposed to change image cache preset to the name I am using. Am I supposed to put this somewhere else as well?

$i = 0;
$output = '';
foreach (element_children($element) as $key) {
  if ($i < 1) {
    $item = $element[$key]['#item'];
    if (empty($item['filepath'])) {
      continue;
    }
    $i++;
    $alt = isset($item['data']['alt']) ? $item['data']['alt'] : '';
    $title = isset($item['data']['title']) ? $item['data']['title'] : NULL;
    $output .= theme('imagecache', 'imagecache-node-image', $item['filepath'], $alt, $title);
  }
}
return $output;

@fehin

Thanks for the quick response. I did make the field type filefield and I do have a node-image for a imagecache preset. I guess where something is wrong is the naming of my imagecache in the pHP code.

In the imagecache preset listings it is actually named node-image. With that said are you familiar with how the PHP names differ as I have tried numerous variations?

Thanks

For what its worth, i've just created a module to provide an imagecache preset for this situation : http://drupal.org/project/imagefield_single dev version should be released shortly.

I've found a quick workaround to show only the first value of any cck fields in teasers.

With Node displays contributions module:
Copy sites/all/modules/nd_contrib/nd_cck/nd_cck.tpl.php to your theme directory, if it doesn't already exist.
Without Node displays contributions module (plain CCK module):
Copy sites/all/modules/cck/theme/content-field.tpl.php to your theme directory, if it doesn't already exist.

Then edit the copied file in your theme directory, change from

$count++;

to

$count++; if ($teaser) { break; }

And then flush the theme registry.

See ImageField Single module for a drop-in solution. See Display Suite code snippets for custom formatters code.

Marked these issues as duplicates:

• #788548: Limiting output from pictures field?
• #1195756: Group multiple values on field display

Changing title for findability.

Another quick (but not perfect) solution:
- go to admin/build/ds/nd/fields
- create a code field with the following code:

<?php 
$node = node_load($object->nid);
if(isset($node->cck_filed_name[0]['filepath'])) {
print theme('imagecache', 'imagecache_preset', $node->cck_field_name[0]['filepath']);
}
?>

- replace "cck_field_name" and "imagecache_preset" above with the actual names from your setup

I just contributed a module for limiting images and other multiple values display in Drupal 7. I think it might be useful posting it here:

http://drupal.org/project/field_multiple_limit

Also note, that the Drupal 7 version of Display Suite has this built in now, see http://realize.be/limit-number-fields-display-field-ui-display-suite

Sweet, but bad timing.

depends, not everyone uses DS and it would stupid to just install DS for limiting their images in the output. So, it's actually a win for everybody again I guess.

This feature makes so much sense. Thanks for adding it! I'll check it out on Wednesday.
