Detection of a date field empty with the liquid

I have a field of date extended CRM and I want to use the liquid to detect if it is a blank (i.e. no date has been chosen yet)

My code so far (does not work)

{capture datechanged %}

{module_customerfield, 161768, 19984689}

{% for %} endcapture

{% If datechanged == ' '-%}

< p > please select a date < /p >

{% endif %}

The value that appears in the code seems to be an empty string, but there a size value of 10, so I can't use a filter size is

What is the value of a date field empty?

I think I got to work.

I had to assign datechanged | band | size to a variable. The code is now:

{capture datechanged %}

{module_customerfield, 161768, 19984689}

{% for %} endcapture

{% assign datesize = datechanged | band | size %}}

{% If datesize is 0-%}

Please select a date

{% endif %}

That seems to work, but it seems to be an overly complicated way to do.

  • Why most of the tabs open empty with the label "New tab" and "topic: vacuum ' in the address line to the restart of Firefox since installing Firefox 28?"

    I have a system dual-bootable Windows Vista SP2 and Firefox updated to 28 on both systems. Since the update of the tabs more reopen empty with the label "New tab" and "topic: vacuum" in the address line of Firefox is restarted. The tabs that open correctly seem to be those who in fact, I was at the session of prefious. I can recover the missing tabs using the Session Manager to pick up a previous session, but of course it does not pick up the tabs open in future sessions. It seems that the tabs that I go to the session recovered are saved correctly, as indicated above, but which are not revisited in the context of the use of the session retrieved will drop the URL next time that I open Firefox it again.

  • Date field to fill the day

    Hello

    I use Adobe LiveCycle Designer ES4 and I would use the existing date field and when the user chooses the date an additional field would complete the day of the week. Is it possible without too much script used.

    Hello

    It is not very complicated.

    Here's a sample for you: Dateien freigegeben - Acrobat.com

    You just need 7 fields named 'Day' and a small script in the output of your date field event.

    if (not $.isNull) then
      var datePattern = "DD.MM.YYYY"
      var date = Date2Num($.formattedValue, datePattern)
      for i = 0 upto 6 do
      Day[i] = Upper(Num2Date(Sum(date, i), "EEEE"))

  • Access to a folder with the liquid?

    I'm curious to know if there is a way to access the contents of a folder with the liquid, then do something with the files in the folder (for example loop through files and insert them into a page).

    My first thought was to use {module_data}, however, the v3 file system API doesn't support, at least from this post.

    Here's what I want to achieve and I hope someone can help me. If it is at all possible.

    I have a web application and each web app element has a lot of photos associated with the web application element. I need to create a photo gallery for each web application. I've considered using the photo gallery module, however, I do not have the associated workflow because the user has 1) create the photo gallery, which means selecting the folder of images for this gallery. The problem with that is there is a lot of files on the site and each element of web application has its own folder, so you have a lot of files to go. Not easy to pick a folder quickly. (If there is a way to limit that show the records, please let me know.) (Once the photo gallery is created, the user must 2) Insert the photo gallery and enter the ID of the photo gallery and then 3) return to the web application and insert the ID of the web application. While it's feasible, I don't like the workflow for my client. I want it to be faster and easier.

    My goal is to have it so the user can create a folder, download the images in the folder, create the element of web application and the name of the web item app will match the name of the folder. Then I can draw the contents of the folder in the web page of details like a photo gallery app. Quick and simple for the end user.

    Is this possible? Any thoughts?

    Not at the moment, Lynda, it would if the file system went to the V3, but I don't know BC really wants to open this door. They would need confirm if they plan to allow us access on the server front end or not.

  • How to fill my date fields placed on the Master Page to several pages?

    I have a dynamic form with fields flowing. I inserted date fields using the tab of Master Pages in Adobe LiveCycle Designer ES2, Windows 7 operating system. I have only 1 Master Page. Everything on the form works fine, except when I have several pages, date fields are empty on all except the first page. One of the date fields in the event javascript has exit to calculate the second field. I can manually change the fields of date subsequent page (s), but I don't want the end user to have to do. I want that date fields on the new pages to match the date fields in the first pages. Here's my output with notes to provide a visualization of what I'm looking for.

  • calculate a date field first of the month

    I need to calculate a date field using date of hire as a base date, and it should return the first of the month following 30 days of date of hire.  (date of rental + 30 days then first of the month following that date).

    Hello margery497,

    In this scenario, you can create a text field 1 with validation as a calculated field and can add now() formula inside. Then, in the text field 2, you can add the now() + 30 formula and save it with the calculated field.

    Here is the reference for validating field:

  • Script to fill in the date field and disable the form

    Hi all

    With little experience of Adobe I was tasked to create a set of PDF forms to use in my company. I drew using Pro forms, but I need a digital signature field that will fill a separate date field at the signing and also disable some of the fields in the form. For the moment I can get it to do one or the other, but I can't do both.

    Is there a script that I can use for these functions?

    Thank you

    KC

    As you have probably seen, there is an option on the signing tab to run a script when a digital signature is applied.

    Do what you have described what follows can be used (of course, you have to adapt the name of the field):

    this.getField("SignatureTime").value = util.printd ("mm/dd/yyyy", new Date()); Enter the date with the current date

    this.getField("Text1").readonly = true; The value of some fields read-only

    this.getField("Text2").readonly = true;

    this.getField("Text3").readonly = true;

    this.getField("Text4").readonly = true;

    etc.

  • Exclude a combined field data field empty (null)

    Hello

    I have a simple (I hope) question I'm stuck...

    At one point in our form, we ask for the cell at home and work numbers. These are optional.

    later we want to re - use the phone contact information provided earlier

    the second place (call it field X in our example) where these data are using I was going to just go something like

    this.rawValue = A.rawValue + rawValue. b + c. rawValue;

    where A, B, C are cell phone, work fields and home earlier and that = X.

    But this happen inserted fields NULL if the user leaves the initial blank (for example is they only have a cell and thus leave the House empty).

    So I would test to see if the field is null, before it can be used

    can anyone suggest a code that allows the following logic

    x.rawValue = A.rawValue + B.rawValue + C.rawValue SO LONG AS A, B AND C all THE PHONE NUMBERS IN

    otherwise if ONLY A AND B have given then x.rawValue = A.rawValue + B.rawValue

    otherwise if ONLY A and C

    or only has

  • In the PivotTable data not traveling with the question of the form

    Jasmine or someone who can help,

    I have a form with a dynamic table in it. When this form is completed and submitted in the workspace only the first line of this table appears in the next step of the process. Because a signature is required and that and all the rest appear in the next step in the process, but the PivotTable is giving me, I submit the form in PDF format.

    I enclose the form. It has a built-in schema and some JavaScript in there basic calculations.

    Thanks for your help,

    Brian

    Your table don't travel with the form is because your drawing is a bit off.

    You have StockNo, descriptionArticlesServices, quantity, unit of issue, unit price estimated amount, amount and propcode.

    Your table is put in place to repeat for each item of data, which is OK, but you have to hand in your schema.  If you want to basically something like this:

    You can then link the text stockNo field in the $record. P1. TableInfo.TableRow [*] .stockNo

    In summary, your schema is currently only showing a single item (no extensible data node), so you can have only 1 piece of data to the entry in the table.

    Hope that helps!  In the affirmative, please mark it as useful or correct!
