One opportunity would be to use a `label` element if it isn't a multilingual site and a `strong` tag if it is one.  What do you think?

Sounds good, thanks.

The idea behind this was that some textformatter like "NewLineToBreak" or "NewLineToListItem" doesn't make that much sense applied to an one liner input element.

True, but the textformatter that I'm thinking of is HTML Entity Encoder, which is important for any text field to avoid ambiguous ampersands or other invalid HTML. The string could be manually encoded in the template but more convenient to set-and-forget with a textformatter. :)

Hi,

Thanks so much - that makes sense... I've tried to combine the below in a lot of different ways but keep getting an error...

Any ideas?

Thanks

<?php
if ($image->caption){
    //Output markup 1
}
else {
    //Output markup 2
}
?>

<?foreach($page->images as $image) {
 $thumb = $image->width(1040); 
echo "<li><img src='$thumb->url' alt='$image->description'><p class='caption'><strong>{$image->imagetitle}</strong> <em>{$image->imagetext}</em> <span><br>{$image->role}</span></p></li>";}
?>

hi!
thanks for this great module!

today I experienced a strange issue when using this module with the Video Fieldtype Module
I get the following error when uploading a video, when the image extra module is installed:

<br />

I testes this in PW 3.0 with the newest versions of both modules installed.
Not sure why its even interfering with the video field..
When I disable the image extra module, everything works fine.

@jploch - I'd like to see a dump of $event after line 718 because $field is not an object and it should be.

That said, a quick fix might be to change the hook on line 97 to:

InputfieldImage::processInputFile

@Jon E 

Just use the comparison inside the foreach loop:

foreach ($page->images as $image) {
  $caption = '';
  if ($image->imagetitle) {
    $caption = "<p class='caption'>{$image->imagetitle}</p>";
  }

  echo "<li><img src='{$image->width(1040)->url}' alt='{$image->description}'>$caption</li>";
}

Or if you want to combine multiple parts: you can check every extra field individually and concatenate the caption before outputting it.

foreach ($page->images as $image) {
  $caption = '';
  if ($image->imagetitle) $caption .= "<strong>{$image->imagetitle}</strong>";
  if ($image->imagetext) $caption .= "<em>{$image->imagetext}</em>";
  if ($image->role) $caption .= "<span>{$image->role}</span>";
  if ($caption) $caption = "<p class='caption'>$caption</p>";

  echo "<li><img src='{$image->width(1040)->url}' alt='{$image->description}'>$caption</li>";
}

Hi there! And, as always, thanks for a perfect product!

Would like to discuss an interesting case. Let's suppose we have some images attached to different pages, each image having some extra fields including uid field which is unique. We have to build an api page which should receive requests like /api?uid=efv97yg and it should return some JSON about the image with that uid.

Is there any possibility to find an image by its extrafield value (e.g. uid)? Well, i know that we can do something like this:

$pages_ = $pages->find('template=page_with_fotos');
foreach($pages_ as $page_)
	{
	$images = $page_->images;
	foreach($images as $image)
		{
		if($image->uid !== $uid) continue;
		$json = json_encode($image);
		break;
		}
	}
echo $json;

But its not very elegant.

And even worse:

$sql = "select * from field_foto where uid=$uid";
$query = $database->prepare($sql);
$query->execute();
...

What is on my wishlist:

//pseudocode, will NOT work for sure!

$foto = $field_fotos->get("uid=$uid");
...

Will appreciate any advice. Thanks!

Just used this module for adding a video link to images. There was a glitch that there was no indication on the thumbnails whether there is a link added or not, so I put together a small js/css combo to add an icon:

has-video.thumb.gif.6e88144313e59ece60e44535eb9dda44.gif

Here is the corresponding code - dirty but works :)

Spoiler

var fieldname = 'video_url_project_images';

function updateVideoItems() {

    $('.gridImage__hover.has-video').removeClass('has-video');

    $('input[id*="video_url_project_images"][value!=""]').each(function() {

        var $item = $(this),
            seekId = $item.attr('id').replace(fieldname, 'file'),
            $target = $('#' + seekId);

        if($target.length) {
            $target.find('.gridImage__hover').addClass('has-video');
        }
    });
}

$(document).ready(function() {
    updateVideoItems();
});

$(document).on('keyup change', 'input[id*="' + fieldname + '"]', function() {
    updateVideoItems();
});

.gridImage__hover.has-video .gridImage__inner::after {
    content: "";
    position: absolute;
    right: 2px;
    bottom: 2px;
    width: 30px;
    height: 30px;
    background: #333 url('/site/templates/images/icons/play-circle.svg') center center no-repeat;
    background-size: 30px;
    border-radius: 100%;
    border: 2px solid white;
    background-clip: content-box;
}

There are two different ways to get the label of any input Field:

echo "This is the field label: {$page->fields->get("simple_slider")->label}";
echo "This is the field label: {$page->fields->get("simple_slider")->getLabel()}";

Let's pretend I added to my image field an extra field "location" with the label "This was in:". So if I want the value of the "location" field I do it like this:

echo "This is was in: {$page->simple_slider->location}";
// Outputs "Barcelona"

How can I get the LABEL of the location field?

Something like:

// not working code:
echo "{$page->fields->get("simple_slider")->location->getLabel()}: {$page->simple_slider->location}";
// Should output "This was in: Barcelona"

Hi,

since extra fields aren't regular ProcessWire fields you cannot access the labels using `->getLabel()` method or `->label` property.
The extra field labels are saved in the regarding field settings (table fields, column data) using json and looks like this:

{"otherFieldSettings":"{\"cf_label\":{\"cf_label__location\":\"Location\",\"cf_label__location__1012\":\"Ort\",\"cf_label__custom__1013\":\"Paikka\"}}"}

You can get the label using this functionality:

$fieldSettings = $fields->get('images')->otherFieldSettings;
$settings = json_decode($fieldSettings);
echo $settings->cf_label->cf_label__location;

As you can see there is no error handling or fallback strategy. Therefore I updated the module and added a method called getExtraLabel()

Usage example:

// outputs something like: "Location: Munich"
echo $image->getExtraLabel('location') . ': ' . $image->location;

// outputs something like: "Ort: München"
echo $image->getExtraLabel('location', 'de') . ': ' . $image->location;

Thanks @mr-fan: there was a little bug figuring out, whether the user is working in the backend or not (differentiate between int(0) und false :D ). The belonging JavaScript file wasn't loaded.

Thank you for the module!

I'm using it to add a Markdown enhanced captions for some blog images. I have a problem - the text is processed by the Mardown module only for the first image (in ProcessWire 3.0.72 multi language).
Could someone give me a hint about where to look, please? I'm stumped.
I'm retrieving them like this:

<?php foreach (pages('parent=8888') as $item) { ?>

    <div>
        <div class="uk-card uk-card-default">

            <?php if (count($item->images)) {
                      $item_image = $item->images->getRandom(); ?>

                <div class="uk-card-media-top">
                    <figure>
                        <img src="<?=$item_image->size(580, 384, ['quality' => 75])->url?>"
                             title="<?=$item_image->description?>"
                             alt="<?=$item_image->description?>">
                        <figcaption class="uk-text-meta uk-padding uk-padding-remove-vertical"><?=$item_image->caption?></figcaption>
                    </figure>
                </div>

            <?php } ?>

            <div class="uk-card-body">
                <h3 class="uk-card-title"><a href="<?=$item->url?>" title=""><?=$item->title?></a></h3>
                <p><?=$item->summary?></p>
            </div>
        </div>
    </div>

<?php } ?>

OK, found the culprit, is the static variable

$alreadyFormatted

which is set to true at line 527 (module version 106):

525  public function formatExtraValue(HookEvent $event) {
526    if (!self::$alreadyFormatted) {
527      self::$alreadyFormatted = true;

I don't know its purpose, but in my case (a loop retrieving captions for an image from every blog post) it stops the text formatter from processing any item after the first one. So I commented it out, I'll see if anything goes wrong.

@geedamed I took me some time but I figured out, what the problem might be. I found a fix, but I do not understand exactly why this is happening. So if anybody could explain this behaviour, feel free to share it :)

 I added the `already formatted` check because in some cases the formatter was called twice (which could break the output). Let's define `in some cases`:

  • images are outputted on the same page as saved to
  • it just counts for the first/one image field

I compared the passed HookEvents. The only difference was that in the first argument, which contains the current Page object, the page title was missing.
So I added a check whether the Page object does contain a title, otherwise skip the formatter. I tested different cases (multiple images, multiple image fields, output from another page and so on). Seems to work – or every extra field the formatter is only called once.

Hi @justb3a I just found your module and I was wondering if you could add a cropping option field with all of it's values: northwest, north, northeast, west, center, east, southwest, south, southeast.

Very useful Module.

Is there a way to hide / unpublish a single image temporarily instead of deleting (trashing) the entire image + information?

A checkbox for this would be great.

Thank you.

@theo: Actually the core/module do support it in a way that's not immediately obvious or as straightforward as checking a checkbox, but it's still quite useful and worthwhile when you need the capability. You could use tags or any other image extra field to achieve this. 

  1. Edit any existing files/images field, or create a new one.

  2. When editing the field settings,  check the box to enable “tags”, or create a new extra field named “hidden“ or something like that.

  3. In the “tags” or “hidden“ field for the image (which should be unpublished), enter a specific phrase like “hidden" (tags field)  or “1“ (hidden field).

  4. Now you need to check if the file should be shown on the front-end of your site. Here's how you do that:

// tag usage example
if (!$image->hasTag('hidden')) echo "<img src='$image->url' alt=''>";

// extra field hidden example
if (!$image->hidden) echo "<img src='$image->url' alt=''>";

 

You could also send a feature request to add this as a core feature (so you do not need to check manually whether the image is hidden and as an extra bonus the hidden images would be visible at first glance using opacity to indicate that).

I'm having an issue with the module. When I add an additional field to an existing image field and try to edit the page I get an error like:

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'field_headerImage.title' in 'field list'

I get a similar but more verbose error on the frontend trying to view the page.

Removing the additional field resumes normal behaviour for the page.

I have other fields that I've added a title field to that work fine, so it's worked in the past, and image fields that already have custom fields have no problem, but I can't add more.

I'm working with the latest build of PW (3.0.79)

Could you please try to rename the field so that it doesn't contain camelCase (capital letters)? For example field_backgroundImages to field_background_images. Have a look at the description: "Any combination of ASCII letters [a-z], numbers [0-9], or underscores (no dashes or spaces)."

Please rename headerImage to header_image (or something like this) and try again.

      Cacheable Placeholders
      This module allows you to have pieces of dynamic content inside cached output. This aims to solve the common problem of having a mostly cacheable site, but with pieces of dynamic output here and there.  Consider this simple example, where you want to output a custom greeting to the current user:
      <h1>Good morning, <?= ucfirst($user->name) ?></h1> This snippet means you can't use the template cache (at least for logged-in users), because each user has a different name. Even if 99% of your output is static, you can only cache the pieces that you know won't include this personal greeting. A more common example would be CSRF tokens for HTML forms - those need to be unique by definition, so you can't cache the form wholesale.
      This module solves this problem by introducing cacheable placeholders - small placeholder tokens that get replaced during every request. The replacement is done inside a Page::render hook so it runs during every request, even if the response is served from the template cache. So you can use something like this:
      <h1>Good morning, {{{greeting}}}</h1> Replacement tokens are defined with a callback function that produces the appropriate output and added to the module through a simple hook:
      // site/ready.php wire()->addHookAfter('CachePlaceholders::getTokens', function (HookEvent $e) { $tokens = $e->return; $tokens['greeting'] = [ 'callback' => function (array $tokenData) { return ucfirst(wire('user')->name); } ]; $e->return = $tokens; }); Tokens can also include parameters that are parsed and passed to the callback function. There are more fully annotated examples and step-by-step instructions in the README on Github!
      Features
      A simple and fast token parser that calls the appropriate callback and runs automatically. Tokens may include multiple named or positional parameters, as well as multi-value parameters. A manual mode that allows you to replace tokens in custom pieces of cached content (useful if you're using the $cache API). Some built-in tokens for common use-cases: CSRF-Tokens, replacing values from superglobals and producing random hexadecimal strings. The token format is completely customizable, all delimiters can be changed to avoid collisions with existing tag parsers or template languages. Links

      This is a lightweight alternative to other newsletter & newsletter-subscription modules.
      You can find the Module in the Modules directory and on Github
      It can subscribe, update, unsubscribe & delete a user in a list in Mailchimp with MailChimp API 3.0. It does not provide any forms or validation, so you can feel free to use your own. To protect your users, it does not save any user data in logs or sends them to an admin.
      This module fits your needs if you...
      ...use Mailchimp as your newsletter / email-automation tool ...want to let users subscribe to your newsletter on your website ...want to use your own form, validation and messages (with or without the wire forms) ...don't want any personal user data saved in any way in your ProcessWire environment (cf. EU data regulation terms) ...like to subscribe, update, unsubscribe or delete users to/from different lists ...like the Mailchimp UI for creating / sending / reviewing email campaigns *I have only tested it with PHP 7.x so far, so use on owners risk
      EDIT:
      Since 0.0.4, instructions and changelog can be found in the README only. You can find it here  🙂
      If you have questions or like to contribute, just post a reply or create an issue or pr on github, thanks!

      Sorry for the convoluted title. I have a problem with Process modules that define a custom page using the page key through getModuleInfo (as demonstrated in this excellent tutorial by @bernhard). Those pages are created automatically when the module is installed. The problem is that the title of the page only gets set in the current language. That's not a problem if the current language (language of the superuser who is installing the module) is the default language; if it isn't, the Process page is missing a title in the default language. This has the very awkward effect that a user using the backend in the default language (or any other language) will see an empty entry in the setup menu:

      This screenshot comes from my Cache Control module which includes a Process page. Now I realize the description sounds obscure, but for us it's a common setup: We a multiple bilingual sites where the default language is German and the second language is English. While the clients use the CMS in German, as a developer I prefer the English interface, so whenever I install a Process module I get this problem.
      As a module author, is there a way to handle this situation? I guess it would be possible to use post-installation hooks or create the pages manually, but I very much prefer the declarative approach. The page title is already translatable (through the __ function), but of course at the time of installation there is no translation, and as far as I'm aware it's not possible to ship translations with a module so they are used automatically. Could this situation be handled better in the core? I would prefer if the module installation process would always set the title of the Process page in the default language, instead of the language of the current user.
