I am trying to figure out how to make a hyperlink in a Livecycle Form which points to a URL which will change on different days that the form is rendered. For example on one day I might want the hyperlink to point to:
mywebsite/mypage?option=XXX
and on another day I want it to point to:
mywebsite/mypage?option=YYY
The XXX and YYY can be passed into the form's data pretty easily as XML, but I just don't know how to make it so that the hyperlink is changed to correspond to this.
Any suggestions?
This can be accomplished with JavaScript in LiveCycle Designer. The following script, placed on the Form's docReady event will let you dynamically change the URL of a text object.
form1::docReady - (JavaScript, client)
// If this code is running on the server, you don't want it to run any code
// that might force a relayout, or you could get stuck in an infinite loop
if (xfa.host.name != "XFAPresentationAgent") {
// You would load the URL that you want into this variable, based on
// whatever XML data is being passed into your form
var sURL = "www.stackoverflow.com"; // mywebsite/mypage?option=xxx
// URLs are encoded in XHTML. In order to change the URL, you need
// to create the right XHTML string and push it into the Text object's
// <value> node. This is a super simple XHTML shell for this purpose.
// You could add all sorts of markup to make your hyperlink look pretty
var sRichText = "<body><p>Foo</p></body>";
// Assuming you have a text object called "Text1" on the form, this
// call will push the rich text into the node. Note that this call
// will force a re-layout of the form
this.resolveNode("Text1").value.exData.loadXML(sRichText, false, true);
}
There are a couple of caveats: URLs in Acrobat are only supported in Acrobat 9.0 and later. So if someone using an older version of Acrobat opens your form, the URLs won't work.
Also, as you can see from the "if (xfa.host.name !=...)" line, this code won't run properly if the form is being generated on the server, because forcing a re-layout of a form during docReady can cause problems on certain older versions of the LiveCycle server. If you do need to run this script on the server, you should probably pick a different event then form::docReady.
I a number of complaints from users in WorkSpace that clicking links opened them in the same tab so they lost their WorkSpace form, and there's no option to change that in Designer 11. I think the solution I came up with for that would work for you too.
I made buttons with no border and no background, and in their click event have this line (in Javascript, run at client)
app.launchURL("http:/stackoverflow.com/", true);
It would be easy to add some logic to choose the right URL based on the day and it doesn't cause any form re-rendering.
In some spots where the hyperlink is in line with other text, I leave the text of the link blue and underlined but with no hyperlink, and just place the button (no background, no border, no caption) over it. Does require positioned and not flowed subforms for that to work, so depending on your layout it could get a little clunky.
Wow, just realized I am super late to the party. Well, for anyone using ES4 facing a similar problem . . .
Ended up using a 3rd party component to manipulate the PDF's hyperlinks...wish there was a better solution as this one costs about $1000.

I'm developing a React App, and I have a backend in NodeJS.
In my Mongo Schema I have an array that stores multiple strings, these strings are some images.
I saved them as base64. Now I want to display them in my app, works perfectly fine with src from img tag, but I want to create a button that allows the user to download those pictures, is there any solution to this? Can I convert back that string and make it downloadable? Thank you very much for you time, I'm waiting for your ideas!
Note: The examples in the snippets will not work live because Stack Overflow sandboxes snippets without allow-downloads, but they should work on your page.
Depending on your exact use case, you have different options. The easiest one would be using an <a> tag with the download attribute instead of a button, like this:
<a download="myImage.gif" href="data:image/gif;base64,R0lGODdhEAAQAMwAAPj7+FmhUYjNfGuxYYDJdYTIeanOpT+DOTuANXi/bGOrWj6CONzv2sPjv2CmV1unU4zPgISg6DJnJ3ImTh8Mtbs00aNP1CZSGy0YqLEn47RgXW8amasW7XWsmmvX2iuXiwAAAAAEAAQAAAFVyAgjmRpnihqGCkpDQPbGkNUOFk6DZqgHCNGg2T4QAQBoIiRSAwBE4VA4FACKgkB5NGReASFZEmxsQ0whPDi9BiACYQAInXhwOUtgCUQoORFCGt/g4QAIQA7">Download GIF</a>
If you need to keep using a button and you want to trigger the download programmatically, you can create an <a> tag (without displaying it) and trigger a click:
const a = document.createElement('a')
a.download = 'myImage.gif'
a.href = 'data:image/gif;base64,R0lGODdhEAAQAMwAAPj7+FmhUYjNfGuxYYDJdYTIeanOpT+DOTuANXi/bGOrWj6CONzv2sPjv2CmV1unU4zPgISg6DJnJ3ImTh8Mtbs00aNP1CZSGy0YqLEn47RgXW8amasW7XWsmmvX2iuXiwAAAAAEAAQAAAFVyAgjmRpnihqGCkpDQPbGkNUOFk6DZqgHCNGg2T4QAQBoIiRSAwBE4VA4FACKgkB5NGReASFZEmxsQ0whPDi9BiACYQAInXhwOUtgCUQoORFCGt/g4QAIQA7'
a.click()
(If you need to support older browsers, you may have to temporarily insert the tag into the DOM and trigger the click in a setTimeout(..., 0).)
You can also use object URLs like it's shown here but it's probably easier to go the data URI route since you already have such a URI.
Umbraco uses angularJS as based library and backoffice totally developed on it. The reason telling first is to tell that I have a field on which URL regular expression applied. If someone entered invalid url like below image
it shows error as need.
But if a user try to remove whole text by selecting it and removing at once. It still keep appearing the error like this
However, if a user erase text one by one like this
then the validation error removed and user need to click on button to see error again.
I would to know how screen 3 state can be achievable when user remove all text together? Its really annoying behavior for a user to remove text character one by one to refresh the state of the field. Screen 3 state should be applied on screen 2.
Can anybody tell me how it can fix or achievable? Right now, it seems like a default behavior.
Looking forward to hear from you guys. Suggestions will be much appreciatable.

I've looked into this issue. This seems to be a product bug.
When you remove whole text at once, newValue is an empty string and the code responsible for resetting error messages doesn't run. If you have access to the umbraco code, you can easily fix it by removing highlighted check:
In my mobile app, we use the docusign API to create a pdf enveloppe in a mobile app and change its content to match our customers expectations.
There are text components of the pdf that I'm supposed to be able to change, like DocuSign_SignerPlacedCompleteConfirm. Problem is, when changing the value, nothing appears on the enveloppe, while the change does happen for other fields.
Our doc includes the Docusign-Signing-Resource-File pdf v2.0 and the original resource file from docusign (master downloaded on their site).
I've already observed a difference between our master resource file and what the doc says about what's inside.
So I guessed that the field key was not the right one and I tried other names for the key, like placing "_Mobile" at the end.
But it still doesn't work.
I really feel like the doc is missing something, and it bothers me as everything looks changeable and this item is supposed to be but I can't get it to change.
<data name="DocuSign_SignerPlacedCompleteConfirm">Bla bla bla</data>
doesn't change the field I want. But
<data name="DocuSign_HelpfulStart_Mobile">Click on START to start</data>
does change something, a text which is near the previous one.
The field I want to change is circled in black here :
Field to change
App is coded in React Native, opens a WebView in which you can see above page, generated by DocuSign.
I can't see any error log from docusign, and I just expect my text in the header to be set at 'Bla bla bla' for example. Instead, it's set at the default value.
I'm sorry Axel, but I'm afraid what you are asking is not possible.
Changing the UI of the actual signature tabs in a signed envelope is not supported at this time.
It is a major security concern to enable this type of change, as it would potentially allow someone to make it look like someone else signed their envelope.
I'm working on an SSRS template at present which pulls lots of its format information from a database. Part of this format information sets the Background Image of cells.
I'm currently filling the image by setting the Source to External and pulling its value from the database. This works lovely, however It means pulling the image from a network source each time and while a small efficiency hit, I'd like to try and remove that pull if possible by embedding the standard images.
Again this works fine, I can pull either an external image or an embedded image and display on screen. The problem comes when I'd like the option to do either.
I find that I cannot set the image Source from a field, there isn't an option in the GUI.
I've tried going into the code and entering the details there but I get a validation error:
The 'http://scemas.microsoft.com/sqlserver/reporting/2008/01/reportdefinition:Source' element is invalid - The value =First(Fields!bodyBackgroundImageSource.Value, "dsTemplate") is invalid according to its datatype String - The Enumeration constraint failed".
Has anyone else come across this and found a solution or know of a workaround? I can continue using only external images, but would prefer to avoid as many external calls as possible.
In our local environment, we tested this scenario and if the expression can return the correct image name, then the image can display properly. You can check if the "First(Fields!bodyBackgroundImageSource.Value, "dsTemplate")" expression return the image name existing under Images folder on Report Data window. And make sure the image source is embedded.
First time poster here, I'm a designer not skilled at all with php and I have a small issue I don't seem to be able to solve. I'm making a site in drupal 7 using a sub theme on zen.
Btw this is a great CMS, even though people say it's really more a developers CMS. I have no trouble to do what I need using views, rules, display suite etc. So a big thank you for all the developers out there making this such a good CMS. But for this apparently simple problem... no module will help me (I think) and I'm kinda stuck.
So here it is: I'd like to add a subtitle next to the title in all my pages.
So what I did was to add a custom field into the content type basic page (machine name: field_sub_title) which is a simple text field.
I uncommented the following line in my template.php
function mytheme_preprocess_page(&$variables, $hook) {
$variables['sub_title'] = t('field_sub_title');
}
Now my question is how do I load the content of my custom field into that variable?
I know i need to change the second part, but I don't have a clue as into what I need to change this.
Displaying the variable into the the page.tpl.php is something I know about so I only need help with the first part.
{EDIT}
Ok I found how to do this :)
I was looking for a solution in the wrong place. I don't need to change any thing in the template.php file.
Just needed to add this bit of code into my page.tpl.php:
<?php
print $node->field_sub_title['und'][0]['value'];
?>
So I'm posting this here for other Drupal newbies struggling with this....
Your solution may work for now, but there may be a more Drupal-y way to handle a problem like this. If you haven't noticed any problems yet, you may find one or more of the following issues down the road:
Someone who doesn't know php or Drupal theming may need to change the way this works.
If you're like me, you may forget where exactly in code this was implemented.
You may see superfluous markup and/or errors on nodes (content) that do not have this sub-title field (ie. event content not having a sub-title field while basic pages and news articles do).
When you add a field to a content type, it will automatically appear anytime content in that content type is displayed. You should be able to add the sub-title field for your page, event or whatever else you need and have it automatically appear in the markup.
You can 'manage display' of a content type to drag and drop the order for fields to appear. You could take it a step further by using a module like Display Suite to add formatting or layout per-content type.
If you feel like this isn't good enough and the markup for the subtitle must be at the same level as the page title (which is rare), at least add an if statement to make your code check to see if the variable is present before trying to print it. I'd also add a new variable and comments for code readability.
<?php
$subtitle = $node->field_sub_title['und'][0]['value'];
if($subtitle){
print $subtitle;
}
?>
Consider using field_get_items or field_view_value, or at least use the LANGUAGE_NONE constant instead of 'und'
See https://api.drupal.org/api/drupal/modules%21field%21field.module/function/field_get_items/7 and https://api.drupal.org/api/drupal/modules!field!field.module/function/field_view_value/7
This has the added benefit of reducing the number of potential security holes you create.
