module ImagePicker Field

[theo]

Here is my first processwire module (beta).

https://github.com/theo222/ImagePickerField

A lot of "first times". First time Github, Markdown and of course PW Modules.

So be gentle please.

I hope it works.

[Noel Boss]

Thank you Theo! What are the main purposes of the module?

[theo]

- You can organize your images the way you want and not necessarily per page / repeater-item. For example using Media Library.

- You can access the same image from different pages. No need to upload it several times.

This can be done in CKEditor, but there was no single field type for this.

One example is a repeater for an image-carousel. You can now put all the images in a Media Page called e.g. "Carousel" and then just pick them up in the repeater's ImagePicker.

- You can also fill in an external Image URL and you will see a preview in the backend.

- You can have an overview of all images in all pages of your site. (Not in Repeaters and Pagetables though)

- Website admins can give backend users (editors) a predefined set of images for a certain field which they can choose from by defining selectors.

- Picking up images is fast with ImagePicker.

 

Thank you.

You need a repeater then.

Wow @theo I like very much!! This work perfectly with Media Library!! I think a lot of people will benefit from it, so, thanks you a lot!! 

About some possible changes, honestly I do not see. Yes multiple images could be good but not essential, it's possible use the Repeater Field. Maybe could better when click on in the image, instead of the link to the media, have the possible to delate the image or have the box for edit the image. But I think this will be more difficult because in this way needs also save the new image and not edit the original.

But anyway this module is very very helpful! Thank you again!

Hello Marco: in the code there is no instruction for restrict the field only to super user...
What happens for a no super admin?

[Marco Ro]

Hi @abmcr,  if you are not super admin when you click on the button to pick the image it opens a windows with Media Files page like you are in the page, so you ca not choose the file to add but you can edit it. 

[theo]

Yes, it probably has to do with the fact, that the page generating the picker list uses an admin template.

The page is in Admin->Setup->Image Picker List.

I have almost no time atm.

Can anybody explain how to make such pages accessible for non superusers?

Thank you.

[theo]

@MarcoPLY

Can you test this?

In ImagePickerList.module (should be in site/modules/ImagePicker/)

Add 'permission' => 'imagepicker' to the getModuleInfo() block

    public static function getModuleInfo() {
        return array(
            'title' => 'ImagePicker Lister',
            'version' => 90,
            'summary' => 'ImagePicker Lister',
            'singular' => true,
            'autoload' => false,
            'permission' => 'imagepicker'
        );
    }

Then as admin in the backend do:

Access -> Permissions -> Add New:

Name: imagepicker

After saving, give it a title like "Image Picker".

Then add this permission to your editor role (Acesss -> Roles).

Try if it works. Maybe you have to log-out and in and refresh modules (Modules->Refresh).

@MarcoPLY

Should work now imo.

Repository is updated. This version also creates and deletes the permission, but you still have to add it to your editor role.

Hi, 

I have a problem to use the size api for resize the images. 

This is an example of my situation:

<?php $features = $pages->find("template=single-design"); ?>
	<?php foreach($features as $product): ?>
		<?php
			$image_big = $product->image_card;
			$image_right = $image_big->size(250,250); // this give me error "call to a member funtion size() on null"
		?>
			<img src="<?= $image_right ?>"> <!-- If I use $image_big the images show up correctly -->
	<?php endforeach; ?>

What I can do for resize the images?

 

I also have try to use the api like in the manual ? - But if I use url the images never show up, also first() doesn't work. 

$image = $page->images->first();
$thumb = $image->size(100, 100)
echo "<img src='$thumb->url'>"

 

[theo]

@MarcoPLY It is all written in the README.

https://github.com/theo222/ImagePickerField

ImagePicker stores an URL not an image object.

[Marco Ro]

Sorry @theo ?! I don't know way I looking in all forums but not in your documentation!! sorry! 

btw post the answer here just if some one will need:

<?php $features = $pages->find("template=single-design"); ?>
	<?php foreach($features as $product): ?>
		<?php
			$image_big = $product->getInputField('image_card')->getImage(); 
			$image_right = $image_big->size(250,250);
		?>
			<img src="<?= $image_right->url ?>"> 
	<?php endforeach; ?>

Hi @theo, 

Do have you ever tried to use api for get the url in a multi language website? Because I notice a problem with the code above. maybe I wrong something, the problem is only when I use a different language.  At moment If I switch to the second language I see the error page with this error:  "Call to a member function width() on null" or size()

Do you know why? What did I do wrong?

 

 

[theo]

@MarcoPLY

I have no idea. I've never used it in this way (resizing the linked image).

Can you try to see what's going wrong? I've no time atm.

Thank you!

[Marco Ro]

Hi @theo,

I tried to fix this but I can't find the way. I think the problem is about the url. I try to debug but there are different situation and I can' find a patter.

So, in home page in the pre-set language this work:

<?php
	$image_forni = $page->getInputField('ima_2')->getImage()->width(600);
	echo "	<img src='" . $image_forni->url . "'>";
?>

But If I change language not work. give me  Uncaught Error: Call to a member function width() on null

I tried $page->getInputField('ima_2')->getImage()->url  in this way for the second language the error is Trying to get property of non-object

 

Inside the page where the url have the language path is like site.com/en/page work in both languages

<?php
$image_forni = $page->getInputField('ima_2')->getImage();
echo "	<img src='" . $image_forni->url . "'>";
?>

But if I use $image_big = $post->getInputField('image_card')->getImage()->width(600); give me back an error in both languages Fatal error: Uncaught Error: Call to a member function width() on null

 

I don't know if this can help you, if you don't have time maybe can give me some tips?

Thank you!

 

[theo]

Yes, I saw this, but I have no answer. I think it has to do with how PW Image works.

But this is not really what ImagePicker is about. I added getImage() only for reading the description.

Not sure anyway if it is a good idea to change the linked image from the picker, so I am probably not going to spend time on this.

But if you get more insight, I could add your contribution to github.

[Marco Ro]

I try look if I can do something, but with me poor skill I think I need your help. I know your are busy, hope to not disturb too much.

Maybe the issue is in the InputfieldImagePicker, could be add extra $field->set ? so that the url can change based on the change of the main URL.

And also, add the possibility to resize the width?

I'm nor sure if InputfieldImagePicker is the right place to make these changes.

anyway if you are busy it's ok, np. 

[theo]

Please try updates on github

https://github.com/theo222/ImagePickerField

[Marco Ro]

Thank you very much @theo. I tried it just now.

So, I tried to use in different pages. In one page works. But In other no. I tried to understand way but I couldn't find a solution.

In the fist language it always works.

I the other language in the page doesn't work give me a Call to a member function width() on null  if I delate the width give me back a src="unknow".

I know you are busy so, I will try again to debug in the next days.
