Fieldtype ColorPicker

Recommended Posts

ColorPicker

Custom Fieldtype/Inputfield for ProcessWire 2.+

This module gives you a new custom Fieldtype. Let's you select a color using a Colorpicker jQuery Plugin. The color selected will be stored in HEX format uppercase: "EAEAEA";

To use it in your template as a background HEX color, you'd simple output the value and prefix it with a #:

echo "background-color: #" . $page->color;


When creating a new field in the admin, you can set a default value the field should be prefilled with when creating a new page. The field supports a "reset" button to be able to set it back to the default value.
The colorpicker used: ColorPicker jQuery Plugin by Eyecon

Since 1.0.6 the colorpicker supports color swatches to add predefined colors for easy selection. Thanks @Rayden for the implementation.
 

How to install:

  • Download the contents of this repository and put the folder renamed as "ColorPicker" into your site/modules/ folder
  • Login to processwire and got to Modules page and click "Check for new modules". You should see a note that two new modules were found. Install the FieldtypeColorPicker module under "Field" section. This will also install the required InputfieldColorPicker at the same time.
  • Done
  • You can now create a new field with the "ColorPicker" Fieldtype.


Get it from modules section: http://modules.proce...e-color-picker/

(can't attach/upload files! what's going on?)

You have probably wasted your generous 500kt (heh heh) quota on old forums already: http://processwire.com/talk/index.php?app=core&module=usercp&tab=core&area=attachments

So maybe that limit could be raised, Pete and Ryan?

About your module, great stuff, I am pretty sure this will come handy! Do you save the hex-value or rgb?

Soma, great idea and it seems to work great. Nice job.

As for the code in there, I think all looks good except that you've got a lot of 'extra' that you don't need. I don't think there's any reason to extend FieldtypeText (?) so I would just start from a fresh Fieldtype instead:

class FieldtypeColorPicker extends Fieldtype {

 public static function getModuleInfo() {
return array(
  'title' => 'ColorPicker',
  'version' => 100,
  'summary' => 'Field that stores a hex color as string in a text field. Color is picked using a jQuery ColorPicker Plugin by http://www.eyecon.ro/colorpicker/',
  'installs' => 'InputfieldColorPicker'
   );
 }

 public function getBlankValue(Page $page, Field $field) {
return 'FFFFFF';
 }

 public function sanitizeValue(Page $page, Field $field, $value) {
return strtoupper(substr($value, 0, 6));
 }

 public function getInputfield(Page $page, Field $field) {
return $this->modules->get('InputfieldColorPicker');
 }

 public function getDatabaseSchema(Field $field) {
$schema = parent::getDatabaseSchema($field);
$schema['data'] = 'CHAR(6) NOT NULL'; // i.e. FFFFFF or 333333 (hex color codes)
return $schema;
 }
}

Likewise, your Inputfield had a lot of extra functions and stuff in there that you didn't need. So you could reduce it to this:

<?php
class InputfieldColorPicker extends Inputfield {

 public static function getModuleInfo() {
return array(
  'title' => 'ColorPicker',
  'version' => 100,
  'summary' => 'Provides and ColorPicker interface for defining hex color.',
  'requires' => array("FieldtypeColorPicker")
  );
 }

 public function __construct() {
parent::__construct();
$this->setAttribute('type', 'hidden');
 }

 public function init() {
parent::init();
$this->config->styles->add($this->config->urls->InputfieldColorPicker . "colorpicker/css/colorpicker.css");
$this->config->scripts->add($this->config->urls->InputfieldColorPicker . "colorpicker/js/colorpicker.js");  
 }

 public function ___render() {
$out = "\n<p><div id='ColorPicker_$this->name' style='border:2px solid #444;display:block;width:40px;height:40px;background-color:#".$this->value."'></div>";
$out .= "<input " . $this->getAttributesString() . " /></p>";
$out .= <<<_OUT

<script type='text/javascript'>
$('#ColorPicker_$this->name').ColorPicker({
 color: '#$this->value',
 onShow: function (colpkr) {
$(colpkr).fadeIn(500);
return false;
 },
 onHide: function (colpkr) {
$(colpkr).fadeOut(500);
return false;
 },
 onChange: function (hsb, hex, rgb) {
$('#ColorPicker_$this->name').css('backgroundColor', '#' + hex);
$('#Inputfield_$this->name').val(hex);
 }
});

</script>

_OUT;

return $out;
 }
}

@apeisa, I don't know if it got to do with limited space? ... switched to extended post options ... ok now that is funny, that has to be most funny notice I've seen. There's this line I didn't payed attention closely yet but it says: "Used 2.84MB of your 500K global upload quota (Max. single file size: 100MB)" :D

And yes it's stored as hex. I also thought about wether to chose rgb or hex. And I can't really tell as there's so many option possible, so I just went with hex. I don't know if a converted function or a separate fieldtype or a config option would be best. I haven't really put much more time into it for now, but now that it's working it's time to consider some more possible options.

@ryan, you're awesome, you just made my day. Seriously you helped me really a lot just by doing this cleanup. This is great, as I was also thinking about what could still be removed that's not necessary, but I struggled a lot because I'm still learning this stuff. Thanks for the better database shema! Haven't really taken care of that, oh well. Good idea. I will study it to get a little more clear on fieldtypes. Basicly I wasn't sure what really would be needed to create a new one and thought extending text field would be ok, so I copied the text fieldtype code and deleted some stuff but I guess it was a little off still :D I will implement the changes now and update the rep.

Thanks so much for your help!

Ok, I cleaned up the code and tested it. I just comited a new version to github.

  • improved database schema
  • removed a lot of not needed functions and code
  • fixed an issue where it wouldn't trigger a change on the hidden form text input, now works with "isdirty" type of js checks, i.e. for save reminder type modules

Thanks again Ryan. I may will get back with some questions... but need some sleep now :D

Thanks Adam, didn't really notice somethings wrong (wrong method name) when recently adding version to scripts. It's fixed in latest commit. You should be able to install it sucessfully.

Yeah, I noticed, thanks.

If the MM has update function, can you update the version on modules.processwire.com ? I'd love to try that :) [sorry for DP both here and on GH]

Hi,

Great module! Is it possible to give an example on how to use it in the templates? Thanks in advance!

Wim

Found it :)

It's just $page->field_color

Welcome!

Thanks, glad you found it out on your own. I wanted to add that you also need echo it ;)

echo $page->field_color;

Call me stupid (please don't, I may cry) but how do you actually use this? Can you use it to style things in the CSS?

Would you need to use inline styles?

just an example:

<style>
body{

You could create a styles.php template. And add your colorpicker there.

then on top of that PHP file:

<?php header("Content-type: text/css"); ?>

You could also output it as a js var and use it in scripts.

<script>
 var mycolor = "#<?php echo $page->color?>";

I wanted to use Soma's Sliders to generate hsl colours.( 3 sliders ) But Older IE needs rgb.

here's just a bunch of code I used/created to manage it.

maybe helpful.

You could create a styles.php template. And add your colorpicker there.

then on top of that PHP file:

<?php header("Content-type: text/css"); ?>

Martijn, can you give any more information on how to get this working. Did you rename your style.css file to style.php and update it in the head tag?

That's what I did but don't think PW likes it as the page is coming up unstyled?

OK think I've sorted it you have to store php scripts outside the templates folder.

However, it's not parsing my variables, I'm getting "undefined variable"

Just found a possible issue. I can't seem to get colorpicker fields to work from within a fieldset tab?

When I click on the colour, nothing comes up, but the same field works fine outside of a fieldset?

I'm on the latest dev version of PW - not sure if that's relevant.

Thanks onjegolders for the report. I just updated the module to also work in tabs. It had to do that the init script was executed immediately before wiretabs.

      Hello community!

      I want to share a new module I've been working on that I think could be a big boost for multi-language ProcessWire sites.

      Some background, I was looking for a way for our company website to be efficiently translated as working with human translators was pretty laborious and a lack of updating content created a divergence between languages. I, and several other devs here, have talked about translation integrations and have recognized the power that DeepL has. DeepL is an AI deep learning powered service that delivers translation quality beyond any automated service available. After access to the API was opened up to the US, I built Fluency, a DeepL translation integration for ProcessWire.
      Fluency brings automated translation to every multi-language field in the admin, and also provides a translation tool allowing the user to translate their text to any language without it being inside a template's field. With Fluency you can:
      Translate any plain textarea or text input Translate any CKEditor content (yes, with markup) Translate page names for fully localized URLs on every page Translate your in-template translation function wrapped strings Translate modules DeepL offers translations to the following languages: English (US), English (UK), German, French, Spanish, Portuguese (EU), Portuguese (Brazil, Italian, Dutch, Polish, Russian, Japanese, Chinese (Simplified)
      Installation and usage is completely plug and play. Whether you're building a new multi-language site, need to update a site to multi-language, or simply want to stop manually translating a site and make any language a one-click deal, it could not be easier to do it. Fluency works by having you match the languages configured in ProcessWIre to DeepL's. You can have your site translating to any or all of the languages DeepL translates to in minutes (quite literally).
      Let's break out the screenshots...
      When the default language tab is shown, a message is displayed to let users know that translation is available. Clicking on each tab shows a link that says "Translate from English". Clicking it shows an animated overlay with the word "Translating..." cycling through each language and a light gradient shift. Have a CKEditor field? All good. Fluency will translated it and use DeepL's ability to translate text within HTML tags. CKEditor fields can be translated as easily and accurately as text/textarea fields.

      Repeaters and AJAX created fields also have translation enabled thanks to a JavaScript MutationObserver that searches for multi-language fields and adds translation as they're inserted into the DOM. If there's a multi-language field on the page, it will have translation added.

      Same goes for image description fields. Multi-language SEO friendly images are good to go.

      Creating a new page from one of your templates? Translate your title, and also translate your page name for native language URLs. (Not available for Russian, Chinese, or Japanese languages due to URL limitations). These can be changed in the "Settings" tab for any page as well so whether you're translating new pages or existing pages, you control the URLs everywhere.

      Language configuration pages are no different. Translate the names of your languages and search for both Site Translation Files (including all of your modules)

      Translate all of the static text in your templates as well. Notice that the placeholders are retained. DeepL is pretty good at recognizing and keeping non-translatable strings like that. If it is changed, it's easy to fix manually.

      Fluency adds a "Translate" item to the CMS header. When clicked this opens up a modal with a full translation tool that lets the user translate any language to any language. No need to leave the admin if you need to translate content from a secondary language back to the default ProcessWire language. There is also a button to get the current API usage statistics. DeepL account owners can set billing limitations via character count to control costs. This may help larger sites or sites being retrofitted keep an eye on their usage. This tool is available for all users with the page-edit permission.

      It couldn't be easier to add Fluency to your new or existing website. Simply add your API key and you're shown what languages are currently available for translation from/to as provided by DeepL. This list and all configuration options are taken live from the API so when DeepL releases new languages you can add them to your site without any work. No module updates, just an easy configuration. Just match the language you configured in ProcessWire to the DeepL language you want it to be associated with and you're done. Fluency also allows you to create a list of words/phrases that will not be translated which can prevent items such as brands and company names from being translated when they shouldn't

       
      Limitations:
      No "translate page" - Translating multiple fields can be done by clicking multiple translation links on multiple fields at once but engineering a "one click page translate" is not feasible from a user experience standpoint. The time it takes to translate one field can be a second or two, but cumulatively that may take much longer (CKEditor fields are slower than plain text fields). There may be a workaround in the future but it isn't currently on the roadmap. No "translate site" - Same thing goes for translating an entire website at once. It would be great, but it would be a very intense process and take a very (very) long time. There may be a workaround in the future but it isn't on the roadmap. No current support for Inline CKEditor fields - Handling for CKEditor on-demand hasn't been implemented yet, this is planned for a future release though and can be done. I just forgot about it because I've never really used that feature personally.. Alpha release - This module is in alpha. Releases should be stable and usable, but there may be edge case issues. Test the module thoroughly and please report any bugs via a Gitlab issue on the repository or respond here. Please note that the browser plugin for Grammarly conflicts with Fluency (as it does with many web applications). To address this issue it is recommended that you disable Grammarly when using Fluency, or open the admin to edit pages in a private window where Grammarly may not be loaded. This is an issue that may not have a resolution as creating a workaround may not be possible. If you have insight as to how this may be solved please visit the Gitlab page and file a bugfix ticket.
      Requirements:
      ProcessWire  3.0+ UIKit Admin Theme That's Fluency in a nutshell. A core effort in this module is to create it so that there is nothing DeepL related hard-coded in that would require updating it when DeepL offers new languages. I would like this to be a future-friendly module that doesn't require developer work to keep it up-to-date.
      It's Free
      This is my first real module and I want to give it back to the community as thanks. This is the best CMS I've worked with (thank you Ryan & contributors) and a great community (thank you dear reader). The only cost to use this is a subscription fee for the DeepL Pro API.

      PageImage Manipulator, API for version 1 & 2

      The Page Image Manipulator is a module that let you in a first place do ImageManipulations with your PageImages. - And in a second place there is the possibility to let it work on any imagefile that exists in your servers filesystem, regardless if it is a 'known PW-image'.

      The Page Image Manipulator is a Toolbox for Users and Moduledevelopers. It is written to be as close to the Core ImageSizer as possible. Besides the GD-filterfunctions it contains resize, crop, canvas, rotate, flip, sharpen, unsharpMask and 3 watermark methods.



      How does it work?

      You can enter the ImageManipulator by calling the method pim2Load(). After that you can chain together how many actions in what ever order you like. If your manipulation is finished, you call pimSave() to write the memory Image into a diskfile. pimSave() returns the PageImage-Object of the new written file so we are able to further use any known PW-image property or method. This way it integrates best into the ProcessWire flow.

      The three examples above put out the same visual result: a grayscale image with a width of 240px. Only the filenames will slightly differ.

      You have to define a name-prefix that you pass with the pimLoad() method. If the file with that prefix already exists, all operations are skipped and only the desired PageImage-Object gets returned by pimSave(). If you want to force recreation of the file, you can pass as second param a boolean true: pim2Load('myPrefix', true).

      You may also want to get rid of all variations at once? Than you can call $pageimage->pim2Load('myPrefix')->removePimVariations()!

      A complete list of all methods and actions are at the end of this post.

      For every valid option there is also a single method that you can call, like setQuality(90), setUpscaling(false), etc.
      -------------------------------------------------------------------

      * pimSave

      pimSave()
      return: PageImage-Object If a new image is hold in memory, it saves the current content into a diskfile, according to the settings of filename, imagetype, targetFilename and outputFormat. Returns a PageImage-Object!
      -------------------------------------------------------------------

      * release

      release()
      return: void (nothing) if you, for what ever reason, first load image into memory but than do not save it, you should call release() to do the dishes! 😉 If you use pimSave() to leave the ImageManipulator, release() is called automatically.

      * getOptions

      getOptions()
      return: associative array with all final option values example:

      smooth($level=127)
      param: $level - (integer) 1 - 255, default is 127 return: pim - (class handle) Smooth is the opposite of sharpen. You can define how strong it should be applied, 1 is low and 255 is strong.
      -------------------------------------------------------------------

      * blur

      blur()

      * setMemoryImage

      setMemoryImage($memoryImage)
      param: $memoryImage - (GD-Resource) return: pim - (class handle) If you are ready with your own image stuff, you can check in the memory image for further use with the class.
      -------------------------------------------------------------------

      * watermarkLogo

      watermarkLogo($pngAlphaImage, $position='center', $padding=2)
      param: $pngAlphaImage - mixed [systemfilepath or PageImageObject] to/from a PNG with transparency param: $position - (string) is one out of: N, E, S, W, C, NE, SE, SW, NW,
      - or: north, east, south, west, center, northeast, southeast, southwest, northwest
      default is 'center' param: $padding - (integer) 0 - 25, default is 5, padding to the borders in percent of the images length! return: pim - (class handle) You can pass a transparent image with its filename or as a PageImage to the method. If the watermark is bigger than the destination-image, it gets shrinked to fit into the targetimage. If it is a small watermark image you can define the position of it:
      NW - N - NE | | | W - C - E | | | SW - S - SE  
      The easiest and best way I have discovered to apply a big transparency watermark to an image is as follows:
      create a square transparent png image of e.g. 2000 x 2000 px, place your mark into the center with enough (percent) of space to the borders. You can see an example here! The $pngAlphaImage get centered and shrinked to fit into the memory image. No hassle with what width and / or height should I use?, how many space for the borders?, etc.
      -------------------------------------------------------------------

      * watermarkLogoTiled

      watermarkLogoTiled($pngAlphaImage)
      param: $pngAlphaImage - mixed [systemfilepath or PageImageObject] to/from a PNG with transparency return: pim - (class handle) Here you have to pass a tile png with transparency (e.g. something between 150-300 px?) to your bigger images. It got repeated all over the memory image starting at the top left corner.
      -------------------------------------------------------------------

      * watermarkText

      watermarkText($text, $size=10, $position='center', $padding=2, $opacity=50, $trueTypeFont=null)
      param: $text - (string) the text that you want to display on the image param: $size - (integer) 1 - 100, unit = points, good value seems to be around 10 to 15 param: $position - (string) is one out of: N, E, S, W, C, NE, SE, SW, NW,
      - or: north, east, south, west, center, northeast, southeast, southwest, northwest
      default is 'center' param: $padding - (integer) 0 - 25, default is 2, padding to the borders in percent of the images length! param: $opacity- (integer) 1 - 100, default is 50 param: $trueTypeFont - (string) systemfilepath to a TrueTypeFont, default is freesansbold.ttf (is GPL & comes with the module) return: pim - (class handle) Here you can display (dynamic) text with transparency over the memory image. You have to define your text, and optionally size, position, padding, opacity for it. And if you don't like the default font, freesansbold, you have to point to a TrueTypeFont-File of your choice.

      PageImage Manipulator - Example Output


    • By d'Hinnisdaël
      Format Datetime fields as Carbon instances.
      You can find the latest release and the complete readme on Github.
      Installation
      composer require daun/datetime-carbon-format Usage
      All Datetime fields will now be formatted as Carbon instances instead of strings. Some examples:
      // $page->date is a Datetime field // Output format: j/n/Y echo $page->date; // 20/10/2020 echo $page->date->add('7 days'); // 27/10/2020 echo $page->date->format('l, F j'); // Monday, October 20 echo $page->date->year; // 2020 echo $page->date->diffForHumans(); // 28 minutes ago Frontend only
      The ProcessWire admin seems to expect datetime fields to be strings. This module will only return Carbon instances on frontend page views.
      Date output format
      When casting a Carbon instance to a string (usually when outputting the field in a template), the field's date output format will be respected.

      TrelloWire
      This is a module that allows you to automatically create Trello cards for ProcessWire pages and update them when the pages are updated. This allows you to setup connected workflows. Card properties and change handling behaviour can be customized through the extensive module configuration. Every action the module performs is hookable, so you can modify when and how cards are created as much as you need to. The module also contains an API-component that makes it easy to make requests to the Trello API and build your own connected ProcessWire-Trello workflows.
      Warning: This module requires ProcessWire 3.0.167 which is above the current stable master release at the moment.
      Features
      All the things the module can do for you without any custom code: Create a new card on Trello whenever a page is added or published (you can select applicable templates). Configure the target board, target list, name and description for new cards. Add default labels and checklists to the card. Update the card whenever the page is updated (optional). When the status of the card changes (published / unpublished, hidden / unhidden, trashed / restored or deleted), move the card to a different list or archive or delete it (configurable). You can extend this through hooks in many ways: Modifiy when and how cards are created. Modify the card properties (Target board & list, title, description, et c.) before they are sent to Trello. Create your own workflows by utilizing an API helper class with many convenient utility methods to access the Trello API directly. Feedback & Future Plans
      Let me know what you think! In particular:
      If you find any bugs report them here or on Github, I'll try to fix them. This module was born out of a use-case for a client project where we manage new form submissions through Trello. I'm not sure how many use-cases there are for this module. If you do use it, tell me about it! The Trello API is pretty extensive, I'll try to add some more helper methods to the TrelloWireApi class (let me know if you need anything in particular). I'll think about how the module can support different workflows that include Twig – talk to me if you have a use-case! Next steps could be a dashboard to manage pages that are connected to a Trello card, or a new section in the settings tab to manage the Trello connection. But it depends on whether there is any interest in this 🙂 Links
