How can I get the Asset Entry in a Freemarker (a Fragment, Widget Template, Web Content Template, etc) inside a Display Page.
You can use INFO_ITEM_DETAILS object from Request global variable, to get the Asset className and classPK, and then recover your Display Page Asset with AssetEntryLocalService
<#assign assetEntryLocalService = serviceLocator.findService("com.liferay.asset.kernel.service.AssetEntryLocalService")/>
<#if Request.INFO_ITEM_DETAILS??>
<#assign
info_item_reference = Request.INFO_ITEM_DETAILS.getInfoItemReference()
className = info_item_reference.getClassName()
classPK = info_item_reference.getClassPK()
asset = assetEntryLocalService.getEntry(className, classPK)
/>
${asset}
</#if>
make sure to use Freemarker's alternative (square bracket) syntax
when creating a Fragment

I'm using the "Allowed html tags" filter in Ckeditor - Drupal 8.
I want Ckeditor to keep <span> tags that have specific classes or IDs, and to remove if it has no attribute.
For example :
Keep span: <span class="apple">text sample</span>
Keep span : <span id="fruit">text sample</span>
Remove span : <span>text sample</span> -> text sample
Actually, when I configure a text format, I have this code in the allowed tags field :
<p><sup><sub><span id class="apple"><a href !href accesskey id rel target title>
It keeps <span> with IDs or wanted classes, but I cannot get rid of the unwanted <span> with no attribute.
Is there any way to solve this problem with code input?
Thanks in advance,
Emilie
So here is the custom module I wrote to make it work and to get around this major bug in CKEDITOR :
<?php
use Drupal\editor\Entity\Editor;
function MODULENAME_editor_js_settings_alter(array &$settings) {
foreach ($settings['editor']['formats'] as $name => $value) {
$settings['editor']['formats']['machine_name_of_your_text_editor_profile']
['editorSettings']['allowedContent'] =
'p sup h1 h2 h3' +
'span[!id];
span(!foo);
span(!bar);
span(!jane);
span(!doe);'
;}
}
Result : spans are totally deleted if there is no ID, or if you use a class that is not mentionned in this list (foo, bar, jane or doe). You must declare all elements you need to be displayed, because this config will overwrite all previous inputs in the ACF field.
For this solution, I was inspired by :
The ACF Custom doc : https://ckeditor.com/docs/ckeditor4/latest/examples/acfcustom.html
A tread about hook_editor_js_settings_alter : https://drupal.stackexchange.com/questions/268311/hook-editor-js-setting...
Note : Limit allowed HTML tags and correct faulty HTML filter (in /admin/config/content/formats) does not act consistently with the Ckeditor API. Only a part of the options are really implemented in this field, and uses of "!" don't work. This is why the solution provided uses "hook_editor_js_settings_alter".
function MODULENAME_editor_js_settings_alter(array &$settings) {
$formats = ['basic_html', 'full_html'];
foreach ($formats as $format) {
$settings['editor']['formats'][$format]['editorSettings']['allowedContent']['span']['attributes'] = '!class';
}
}
allowedContent is an array when loaded by Drupal. Instead of replacing it with a string, you can use the ACF rules to specify whether attributes are required. This allows the config from the UI to still apply.
I am trying to create an Advanced PDF/HTML template that will display an image using a URL that is in a custom field. The custom field is a hyperlink and the field ID is {custitem_dp_image1}. I am using the image tag and referencing the {custitem_dp_image1} field as the src but I am unable to save the template due to the following error:
java.lang.StringIndexOutOfBoundsException: String index out of range:
0 java.lang.InternalError: java.lang.StringIndexOutOfBoundsException:
String index out of range: 0
I've also tried the following code:
<#if result.custitem_dp_image1?length != 0><img src="${result.custitem_dp_image1}" style="width: 100px; height: 100px;" /> </#if>
But I received the following error when I tried to view the Advanced PDF/HTML template from a Saved Search:
The template cannot be saved due to the following errors:
org.xml.sax.SAXParseException; lineNumber: 53; columnNumber: 28; The value of attribute "src" associated with an element type "img"
must not contain the '<' character.
*The template was stored as invalid.
How can I get this to work and display the image?
The solution is to change the custom field to type = Free-Form Text and use the following freemarker code:
<#if result.custitem_dp_image1?length != 0><img src="${result.custitem_dp_image1}" style="width: 100px; height: 100px;" /> </#if>
Instead of Hyperlink use image datatype for your custom field.
You can also use a workflow to link the Hyperlink custom field to a Free-Form text field with the Store Value field checked.
Look under SuiteAnswers ID: 89195
The Hyperlink field type will return an entire HTML tag when calling for the field like this: ${result.custitem_dp_image1}
image name
So if you add it to the HTML or tag, it would break because it would look something like this:
<img src="image name">
Freemaker has functions to trim data ?keep_after and ?keep_before
So you could use this to bring just the actual URL:
result.custitem_dp_image1?keep_after('href="')?keep_before('"')
In a nutshell, everything after the href=" and everything before the ":
BUT you cant use this inside the "src" tag as it would break the HTML code. You have double quotes inside the Freemaker function and HTML would think the src tag ended at that particular location.
So to circumvent that, I'll insert the code in a variable (either global or assign) and then use just the variable in the SRC tag.
<#global custom_url = result.custitem_dp_image1?keep_after('href="')?keep_before('"')>
<img src="${custom_url}">
Oh, just my 2 cents, Users will likely want to keep the Hyperlink field type as its clickable in the User UI.
I have implemented a module where i m trying to generate a PDF.PDF is generated successfully using MVCRAZORtppdf.
But now I want to add a image on PDF as well.How to add a image on PDF. And I want to add image on controller level.
Here is my solution done completely inside view:
#{
Layout = null;
var imagePath = Server.MapPath("~/Content/images");
....
}
<body>
....
<img src="#imagePath\Cert_back.bmp" />
....
</body>
If you want to set an image in Controller, I guess you can use ViewBag to set value in imagePath variable.
However, keep in mind that you can use Razor's if-then-else statement and set value dynamically in View.
I'm trying to write a docpad plugin that will allow me to insert meta tags unique to each page, for example og:title or og:description. I've been able to accomplish this globally with the populateCollections event for global values, but have not been able to do this per page.
I'd like for this to work without the need for a template function so that the meta tag is inserted automatically based on the document's meta. One way might be to grab the contentRendered value in the writeBefore event and do string manipulation that way, but that seems hacky.
Any ideas?
This worked for what I needed. Basically, I'm getting the rendered content right before the file is written using the writeBefore event, and doing a very simple string replace which adds the meta tags and their unique values, which is pulled from the model in the collection.
writeBefore: (opts) ->
docPad = #docPad
templateData = docpad.getTemplateData()
siteUrl = templateData.site.url
for model in opts.collection.models
if model.get('outExtension') == 'html'
url = #getTag('og:url', siteUrl+model.get('url'))
title = #getTag('og:title', model.get('title'))
content = model.get('contentRendered')
if content
content = content.replace(/<\/title>/, '</title>'+url+title+description)
model.set('contentRendered', content)
# Helper
getTag: (ogName, data) ->
return "\n <meta property=\"#{ogName}\" content=\"#{data}\" />"
Great answer David, leaving this one if someone faced the same issue I did.
Check if meta tag is broken, if it is - don't render:
renderBefore: (opts) ->
for model in opts.collection.models
if model.get('date').toLocaleDateString()=='Invalid Date'
model.set('write', false)
docpad.log model.get('title')+' has broken date format!\n\n\n\n\n'
false
I am using partials in with collections. Adding what is needed in the document like this:
```
title: Meetings and Events
layout: page
description: "This is my custom description."
tags: ['resources']
pageOrder: 3
pageclass: rc-events
```
I needed a custom CSS class by page. Then you can call it in your default template like this.
<div id="main" class="container <%= #document.pageclass %>">
Should be the same for meta
<meta name="description" content="<%= #document.description) %>" />
or check your docpad.coffee file and put together helper function for prepared content based off of a default site value combined with a #document value. Then you can just call something like the default:
<meta name="description" content="<%= #getPreparedDescription() %>" />
Which is built by this helper function:
# Get the prepared site/document description
getPreparedDescription: ->
# if we have a document description, then we should use that, otherwise use the site's description
#document.description or #site.description
Given the following Html.ActionLink:
#Html.ActionLink(Model.dsResults.Tables[0].Rows[i]["title"].ToString(), "ItemLinkClick",
new { itemListID = #Model.dsResults.Tables[0].Rows[i]["ItemListID"], itemPosNum = i+1 }, ...
Data from the model contains HTML in the title field. However, I am unable to display the HTML encoded values. ie. underlined text shows up with the <u>....</u> around it.
I've tried Html.Raw in the text part of the ActionLink, but no go.
Any suggestions?
If you still want to use a helper to create an action link with raw HTML for the link text then I don't believe you can use Html.ActionLink. However, the answer to this stackoverflow question describes creating a helper which does this.
I would write the link HTML manually though and use the Url.Action helper which creates the URL which Html.ActionLink would have created:
<a href="#Url.Action("ItemLinkClick", new { itemListID = #Model.dsResults.Tables[0].Rows[i]["ItemListID"], itemPosNum = i+1 })">
#Html.Raw(Model.dsResults.Tables[0].Rows[i]["title"].ToString())
</a>
MVCHtmlString.Create should do the trick.
Using the actionlink below you do not need to pass html in the model. Let the css class or inline style determine how the href is decorated.
#Html.ActionLink(Model.dsResults.Tables[0].Rows[i]["title"], "ItemLinkClick", "Controller", new { #class = "underline", style="text-decoration: underline" }, null)
those are the cases that you should take the other path
#{
string title = Model.dsResults.Tables[0].Rows[i]["title"].ToString(),
aHref = String.Format("/ItemLinkClick/itemListID={0}&itemPosNum={1}...",
Model.dsResults.Tables[0].Rows[i]["ItemListID"],
i+1);
}
#Html.Raw(title)
Remember that Razor helpers, help you, but you can still do things in the HTML way.
You could also use this:
<a class='btn btn-link'
href='/Mycontroler/MyAction/" + item.ID + "'
data-ajax='true'
data-ajax-method='Get'
data-ajax-mode='InsertionMode.Replace'
data-ajax-update='#Mymodal'>My Comments</a>
