jQuery UI Range Slider Fieldtype

Recommended Posts

Before we can repeat, we can slide! :)

ProcessWire2+ RangeSlider Fieldtype

This fieldtype let's you create slider input fields in the admin using the built in jQuery UI Slider. You can use it as a regular

single value slider, or enable "Range" setting under details of the field edit screen, which gives you two number.

In the front-end templates you can use the field as follows:

If used as single value slider

	echo $page->fieldname

If ranged slider is enabled

echo $page->fieldname->min
echo $page->fieldname->max

Use in selectors strings

With a regular single value slider

	$pages->find("range=120");

If range slider is enabled

	$pages->find("range.min>=100, range.max<120");

It comes with various settings.

-------------------------------------------------------------------

- range enable

- width of slider (%)

- default value

- min value

- max value

- step

- prefix for displayed value(s)

- suffix for displayed value(s)

Download

-------------------------------------------------------------------

You can download the Module from Github.

https://github.com/s...nic/RangeSlider

How to install

-------------------------------------------------------------------

1. Download and place the RangeSlider folder in: /site/modules/

2. In the admin control panel, go to Modules. At the bottom/top of the

screen, click the "Check for New Modules" button.

3. Now scroll to the RangeSlider Fieldtype module and click "Install".

4. Create a new Field with the new "RangeSlider" Fieldtype. Once saved

you can configure the fieldtype, with various options under "Details" tab.

I have made some testing, and installed on different PW installs. But if you find any issue, I'd like to hear.

Have fun!

Thanks, Soma! Looks pretty cool. I'll test it as soon as possible.

Soma, that's a nice one!

Maybe a possibility to optionally define a function for calculating value range to make the value grow non-linearly as you slide could be a nice enhancement.

Could be handled like custom API calls for page ref fields, a field for js code like "return Math.pow({$x})". But that's just an idea.

Thanks guys! Glad you like it.

Thanks for the idea. Not sure where this could be useful though. But something with a "code" field would be possible.

I'm more thinking something to be able to do floats. This could be done with formatter function too. So you could specify digits precision and have 0-1000 would really mean 0-10.00 - but operations like this could be done on output too.

Also there's still some other settings that might be useful but these are more visual than functional. I'll add 1-2 more for type max,min for regular slider.

Well I realized it still isn't as good as I wanted. It has still a text field for storing data. And the fact that it can used as one value and two value range makes it hard to implement with only 1 integer table field. I'm not sure how it would be possible to have 2 integer fields on a fieldtype. So this current version doesn't work with selectors. Would it be possible to have selector like "range[0]>100, range[1]<120" ? I don't understand how selectors works exactly.

Simplest would be for doing ranges is having two single value slider with real integer field type. But I think it's not as ideal. So i'm kinda stuck here and little overwhelmed with how this else could be implemented better.

Edit:

I think I'm on a path that works. Even with page selectors. I'm doing a little more testing and experimenting.

Actually I'm diving a little more int PW's implementation of fieldtypes and how it works.

So it works now like "range.data>100, range.data2<120", and output is array like before $page->range["data"].

Will hopefully get it working soon and update the repo.

Soma great module!! It should be no problem to make your Fieldtype support two integers. Take a look at the FieldtypeMapMarker module for an example of how to have multiple fields in the module. To start you are going to want to have a DB schema something like this:

public function getDatabaseSchema(Field $field) {
   $schema = parent::getDatabaseSchema($field);
   $schema['data'] = 'int NOT NULL default 0'; // min
   $schema['data_max'] = 'int NOT NULL default 0'; // max
   $schema['keys']['data'] = 'KEY data(data, data_max)';
   $schema['keys']['data_max'] = 'KEY data(data_max)';
   return $schema;
}

Basically, use the required 'data' column for one of your pieces of data, and then you can add any other columns you want. I called it 'data_max' here, but you could call it whatever you want.

I was just thinking the other day that it would be great to have a fieldtype like this for when an integer field always falls within a predictable range. This is even better!

One suggestion: How about having the number display editable, in case there is a specific number you need to enter (and there's a large range that might be difficult to hit with the slider)?

I've reworked the whole module to use integer fields and it works a little different now.

Best of it is, it now works in selectors and uses real integers. :)

I have updated the repo on github just now and also the first post to reflect the changes.

If you installed it already you should first uninstall it before updating.

Is this using standard jQuery UI skinning?

Good work neverthless.

Yes this is using jQuery UI skinning. Thanks!

Or you can even use it to set states. For example use it like an option 1,2,3

One suggestion: How about having the number display editable, in case there is a specific number you need to enter (and there's a large range that might be difficult to hit with the slider)?

This would be possible, but then why have a slider? :P This also would require to implement some validation through js or the module.

I suggest, if you have large numbers you can put it in the near and use arrow keys to get to the value you want.

EDIT: Just found that there seems to be a bug with the left range handle not able to move with keyboard arrow keys. I found out that the current jquery 1.6.2 core included in PW is the reason. I copied in latest jquery 1.7.1 and it starts working.

Great work Soma! I'm really liking this fieldtype. I wanted to mention one potential improvement that would be easy to make. Rather than having to use the technical sounding range.data and range.data_max in selectors, wouldn't it be nice if you could use range.min and range.max? If you want to do that, add this to your Fieldtype:

public function getMatchQuery($query, $table, $subfield, $operator, $value) {
   if($subfield == 'min') $subfield = 'data';
   if($subfield == 'max') $subfield = 'data_max';
   return parent::getMatchQuery($query, $table, $subfield, $operator, $value); 
}

Thanks Ryan! Glad you like it.

Wow thanks, did you read my mind? I was about to look for this particular function to see if there's a way to map those. Thanks for pointing out!

I'll quickly put it in and update the repo.

Edit: Just updated the fieldtype, tested and pushed to github.

Now we can use range.min, range.max in selectors!

Thanks a lot Soma! I detected a bug in this last iteration, while trying to use it, on line 81 of InputfieldRangeSlider.module:

  $display = "$( '#RangeSlider_{$this->name}_display1' ).text( '$this->prefix' + ui.value + '$this->suffix');";

  $constrain = "$( '#Inputfield_{$this->name}1' ).val( ui.value );"	   // !!! there is a semicolon missing here
  // for change event checks
  $constrain .= "$( '#Inputfield_{$this->name}1' ).trigger( 'change' );";

When I added the semicolon, everything started working again!

PS: I'm fairly new to web coding and communities, is there a place where I could have posted this bug? (in the Git, or something like that?)

Cheers :)

Thanks tiagoroldao, nice catch! Seems as not much are using it yet, otherwise someone would have run into this. Though it worked with range enabled. :)

Well, you can always open new issue on github repo. It's public. https://github.com/somatonic/RangeSlider/issues

It's fixed and commited. I also improved the module install. You only need to install the FieldtypeRangeSlider and the InputfieldRangeSlider will be installed and deinstalled automaticly. If you already have it installed it's safe to just replace with the new files.

I wonder if this was only a browser-specific issue anyway? I know IE goes crazy when you miss out semicolons, but in other cases other browsers are fine with it.

Nope Peteee, it wasn't working when using single value slider, a missing semicolon will break javascript if it's not the last line :)

Hi Soma, Thanks for the module! I've been testing the slider and was wondering if it's possible to make 0.5 (half) increments. It would be nice to have a score Range field and let the user select between 1-5 and half increments (4.5 stars).

You're welcome landitus. Unfortunately this seems not possible as I know, it is using the jquery UI slider and there's only numbers not floats supported.

You could then maybe use 1-10 and divide them by 2?

Or you could use page field and create 10 pages with the increments and then use them to select. If the range is never gonna change this might be a option too.

Hey there, nice module. I'm using it for percentages to set fluid sizes and such.

I ran into a small issue, it seems like it always ignores the default value - i can't get it to be 100% as default, for example

thanks for any input!

Thanks joe_g for mention it.

I just updated the module and fixed the issue with the default value.

Just committed another update.

I made sure the default value (if any defined) is also being returned by the API even if the page is not yet saved and there's no range value in the Database.

Hi, I want use this with PW 2.4.+ in a Modules-Configpage. Is this possible?

    EDIT: yes it is possible! :)

I have tried the following code but I do something wrong, the slider isn't displayed in the config page:

    EDIT: The settings for minValue, maxValue etc. belongs to the $field, not to the $slider. This was what I have done initially wrong

            $field = $modules->get("InputfieldRangeSlider");
            if(!empty($field) && class_exists('RangeSlider')) {
	            $field->attr('name', 'integer');
                        $slider = new RangeSlider();
                    $field->attr('value', $slider);
                    $field->width = 90;
                    $field->minValue = 1;
                    $field->maxValue = 100;
                    $field->defaultValue = $data['integer']>0 && $data['integer']<=100 ? $data['integer'] : 50;
                    $field->step = 1;
	            $field->label = 'Test with integer value';
	            $fieldset->add($field);
            } else {
            ...

The only thing what is not working is the $field->defaultValue, - what I'm doing wrong here?

      Checkbox Reversed
      Modifies InputfieldCheckbox so that it shows the reverse of its true value. The checkbox will be unchecked when the field value is 1 and checked when the field value is not 1.
      Background
      The core FieldtypeCheckbox does not have a setting that allows a checkbox to be checked by default. One reason for this is that only a checked field saves a value to the database. An unchecked field does not save "0" to the database, but rather does not save any value for the field at all. Therefore there is no way to distinguish between a new field that has not yet been saved (and therefore could potentially get a default checked state) and a field that has deliberately been saved as unchecked.
      Because of this you sometimes have to use a checkbox in the opposite way than you would like. Suppose your client has requested a checkbox labelled "Bootylicious" that will be checked by default. This isn't possible with FieldtypeCheckbox so instead you have to convince them that a checkbox labelled "Not bootylicious" that is unchecked by default is just as good. This alternative will achieve the same thing, but it's not ideal.
      A solution
      This module doesn't change the limitations of the core checkbox field, but it provides a workaround that allows you to show the checkbox with the desired default state and label. So in the example above you would still name the field "not_bootylicious" (otherwise it could get confusing in your template files) but you can label the field "Bootylicious" and the checkbox will appear checked when its true value is actually unchecked, and vice versa. This allows new pages to show the checkbox checked by default. Clear as mud?
      Usage
      Install the Checkbox Reversed module.
      For any Checkbox field where you want the inputfield to show the reverse of its true value, activate the "Reverse the checked state of this inputfield?" option in the field settings.

      I have been following @bernhard's great tutorial on creating a Dashboard and everything has very easy to understand so far. However, I need to add a select field that a template is using (so users can create a new page from the dashboard), but I am really at a complete lost on how to achieve this. I have been googling, but can't really find anything on the matter.
      $field = $this->modules->get('InputfieldSelect'); $field->name = "Select Manufacturer"; $field->findPagesSelector = "template=basic-page"; //not needed for select field $field->labelFieldName = "title"; $field->name = "Manufacturer Select"; $field->columnWidth = 34; $fieldset->add($field); I have the above code, which was originally an InputfieldPage, but since this is an options field, I have changed it. Has anyone actually gotten a select from a template (and its' values) in a module?

      Video or Social Post Embed
      Based on the TextformatterVideoEmbed module developed by Ryan Cramer, we have added the possibility to embed publications of the main social networks Facebook, Twitter and Instagram.
      ProcessWire Textformatter module that enables translation of YouTube, Vimeo, Instagram, Facebook, Twitter or Issuu URLs to full embed codes, resulting in a viewable video or social post in textarea fields you apply it to.
      How to install
      Download or Clone from Github: https://github.com/lexsanchez/VideoOrSocialPostEmbed
      Copy the VideoOrSocialPostEmbed.module file to your /site/modules/ directory (or place it in /site/modules/VideoOrSocialPostEmbed/).
      Click check for new modules in ProcessWire Admin Modules screen. Click install for the module labeled: "Video or Social Post Embed".
      Now you will be on the module config screen. Please make note of the config options and set as you see fit.
      How to use
      Edit your body field in Setup > Fields (or whatever field(s) you will be placing videos in). On the details tab, find the Text Formatters field and select "Video or Social Post Embed". Save.
      Edit a page using the field you edited and paste in YouTube, Vimeo, Facebook, Twitter, Instagram and/or Issuu URLs each on their own paragraph.
      Example
      How it might look in your editor (like TinyMCE):
      How it works
      This module uses YouTube, Vimeo, Instagram, Facebook, Twitter and Issuu oEmbed services to generate the embed codes populated in your content. After these services are queried the first time, the embed code is cached so that it doesn't need to be pulled again.
      Configuration
      You may want to update the max width and max height settings on the module's configuration screen. You should make these consistent with what is supported by your site design.
      If you change these max width / max height settings you may also want to check the box to clear cache, so that YouTube/Vimeo/Facebook/Twitter/Instagram/Issuu oembed services will generate new embed codes for you.
      Using with Markdown, Textile or other LML
      This text formatter is looking for a YouTube, Vimeo, Instagram, Facebook, Twitter or Issuu video URL surrounded by paragraph tags. As a result, if you are using Markdown or Textile (or something else like it) you want that text formatter to run before this one. That ensures that the expected paragraph tags will be present when VideoOrSocialPostEmbed runs. You can control the order that text formatters are run in by drag/drop sorting in the field editor.
