I'm hoping someone can help me with a challenge I am unable to find a solution for. I need to create an interactive form within a PDF document. One of the main issues is that I have 3 fields where I require an Integer input from the user. After all 3 fields are filled out, I need to ensure that the result is equal to 100%. Is this something that is even possible?
I hope my question makes sense. On a general level, I suppose I need to know whether I can apply programmatic validation to a PDF Form Field, and be able to determine the value of other fields within that same PDF document.
Thank you kindly in advance!
You can use JavaScript for Acrobat in order to achieve this.

We regularly need to perform a handful of relatively simple tests against a bunch of MS Word documents. As these checks are currently done manually, I am striving for a way to automate this. For example:
Check if every page actually has a page number and verify that it is correct.
Verify that a version identifier in the page header is identical across all pages.
Check if the document has a table of contents.
Check if the document has a table of figures.
Check if every figure has a caption.
et cetera. Is this reasonably feasible using PowerShell in conjunction with a Word API?
Powershell can access Word via its object model/Interop (on Windows, at any rate) and AIUI can also work with the Office Open XML OOXML) API, so really you should be able to write any checks you want on the document content. What is slightly less obvious is how you verify that the document content will result in a particular "printed appearance". I'm going to start with some comments on the details first.
Just bear in mind that in the following notes I'm just pointing out a few things that you might have to deal with. If you're examining documents produced by an organisation where people are already broadly speaking following the same standards, it may be easier.
Of the 5 examples you give, without checking the details I couldn't say exactly how you would do them, and there could be difficulties with all of them, but for example
Check if every page actually has a page number and verify that it is correct.
Difficult using either OOXML or the object model, because what you would really be checking is that the header for a particular section had a visible { PAGE } field code. Because that field code might be nested inside other fields that say "if don't display this field code", it's not so easy to be sure that there would be a page number.
Which is what I mean by checking the document's "printed appearance" - if, for example, you can use the object model to print to PDF and have some mechanism that lets PS inspect the PDF's content, that might be a better approach.
Verify that a version identifier in the page header is identical across all pages.
Similar problem to the above, IMO. It depends partly on how the version identifier might be inserted. Is it just a piece of text? Could it be constructed from a number of fields? Might it reference Document Properties or Variables, or Custom XML content?
Check if the document has a table of contents.
Perhaps enough to look for a TOC field that does not have certain options, such as a \c option that a Table of Figures would contain.
Check if the document has a table of figures.
Perhaps enough to check for a TOC field that does have a \c option, perhaps with a specific parameter such as "Figure"
Check if every figure has a caption.
Not sure that you can tell whether a particular image is "a Figure". But if you mean "verify that every graphic object has a caption", you could probably iterate through the inline and floating graphics in the document and verify that there was something that looked like a Word standard caption paragraph within a certain distance of that object. Word has two standard field code patterns for captions AFAIK (one where the chapter number is included and one where it isn't), so you could look for those. You could measure a distance between the image and the caption by ensuring that they were no more than a predefined number of paragraphs apart, or in the case of a floating image, perhaps that the paragraph anchoring the image was no more than so many paragraphs away from the caption.
A couple of more general problems that you might have to deal with:
- just because a document contains a certain feature, such as a ToC field, does not mean that it is visible. A TOC field might have been formatted as not visible. Even harder to detect, it could have been formatted as colored white.
- change tracking. You might have to use the Word object model to "accept changes" before checking whether any given feature is actually there or not. Unless you can find existing code that would help you do that using the OOXML representation of the document, that's probably a strong case for doing checks via the object model.
Some final observations
for future checks, perhaps worth noting that in principle you could create a "DocumentInspector" that users could call from Word BackStage to perform checks on a document. Not sure you can force users to run it, or that you could create it in PS, but perhaps a useful tool.
longer term, if you are doing a very large number of checks, perhaps worth considering whether you could train a ML model to try to detect problems.
I am working on Access 2007. I have a table with some fields in it. I had created a form from the table and one of the fields of the table is a concatenation of 2 fields from the same table.
There are 2 fields OppNo and Material in the table. I had created a form with these (and others in the table) fields. There is another field OppMat which is blank in the table. However, I had got the data into OppMat field populated as a concatenation of OppNo and Material fields in the form. I am now looking at having the table updated with the data of OppMat from the form to the same corresponding field in the table.
Kindly advise as how I could achieve this.
Thanks and regards,
This might be possible if these cases are met:
The field OppMat ALWAYS has the same structure and you can assure that it does.
Users will not be able or very unlikely to deviate from this structure.
Notably you should use something like Left(), Right(), Mid() and so on. Whatever works best for your structure. You can use the string modifiers: https://msdn.microsoft.com/en-us/library/dd789093.aspx
On the other hand I must admit that I am sceptical if your solutions is the best. Here are my reasons:
Users are unpredictable and will continously deviate from your intended way to use the application.
Using the string functions and fixating on one structure makes your code construction inflexible, hard to maintain if changes occur and prone to errors.
The alternatives seem to be better with little drawback.
My suggestions for alternatives:
Use one textbox for each field so that you have two textboxes. You can even position them that way that it almost looks like it is continous text. But not too much otherwise the user will beconfused.
You can add a label that shows your concatenated fields. But for input you use two different textboxes.
Cheers!
I had a question as to the best way to hook some specific functionality into my Gravity Form.
I have a situation where I want to show a different set of dropdown options based on several different possible ranges of postcodes entered into a field.
One way I've tried to achieve this was with Conditional Statements, but the only problem I'm encountering there is that there are quite broad ranges for the postcodes that aren't super easy to work with, plus a few exceptions.
e.g.
New South Wales post codes can be:
1000, 1999,
2000, 2599,
2619, 2898,
2921, 2999
I could code this as a PHP function to validate and return a state, is there a way to hook that into the functions.php file? Or is there a better way to handle this?
Thanks!
Alright, I managed to come up with a solution for this by using a hidden select field as my conditional and then using on page javascript to check for entries to the postcode field and update the hidden conditional field manually.
I have this form:
https://github.com/totty90/production01_server/blob/master/node_modules/production/client/production/source/class/production/views/insertWorkAsManager/Index.js
https://github.com/totty90/production01_server/tree/master/node_modules/production/client/production/source/class/production/views/insertWorkAsManager
It's not exactly a simple form not even a form yet. It's just a bunch of widgets, but I would like to take advance of the validations on the various fields. How do you suggest to do? As I cant directly apply the Form example in my "form".
Thanks,
qooxdoo supports validation for items in the from and the from in total. This offers the opportunity to validate everything you want. Either you check on a single field basis or on a combination. Check out the following demo which showcases most of the features:

We have spreadsheets of complex product data coming in from multiple sources (internal, customers, vendors).
Since the authorship is so diverse, it's impractical to try governing formatting details such as column order and the number of header-rows.
These CSV spreadsheets will be uploaded to our DB via an existing form.
(My first Zend_Form ... I'm almost done with it)
The user needs to see a sample from a given spreadsheet so they can Map the columns and start-row.
To achieve that, I need to generate an html table of that dynamic content, and weave the form elements in and around the table data.
The user would select which values are to be found in each column, and identify the first row of data (after any header rows).
CLICK HERE to see an example.
(NOTE: Most of my work here is under an NDA, so contrived examples is the best we can get :)
In this example, I'd expect the output to be:
_POST('first_row'=>2, 'column0'=>'mi', 'column1'=>'lName', 'column2'=>'fName', 'column3'=>'gender')
With all those scpecifics mapped/defined, the uploaded spreadsheet can then be parsed and accurate data can be added to the product_history database.
Is ZF a good tool for this particular problem, or should I just write something from scratch?
How would you aproach this?
I am finally JUST BARELY starting to get this ZF stuff straight in my head, and this one has got me totally lost :)
Any and All advice appreciated.

I think in your case, using Zend_Form would be helpful for this situation.
The tricky part to it is of course that your forms are going to be largely dynamically generated on-the-fly based on the header and first row content of the CSV file.
Whether you used Zend_Form, or pure PHP, or some other solution, a lot of what you will be doing is the same (analyzing the CSV, providing dynamic inputs based on the CSV, and then error checking the selections). I think using Zend_Form has the advantage of making something like this very cleanly.
Given Zend_Form's nature, e.g. how it validates existing forms based on the elements added to the Zend_Form itself, you need to take a special approach with the form. Basically, after the user uploads the CSV once, you will create a Zend_Form object based on the number of columns, their positions in the CSV, and the name of the column.
Since you don't want to bother the user to upload the CSV multiple times if they make incorrect selections, I would parse the CSV into some sort of structure, maybe a simple object or array, and then build your Zend_Form based on that data. This way, you can save that structure to the session, so you can continue to regenerate the form based on the parsed data without having to read the file each time. This is because the main challenge with Zend_Form and dynamic forms, is that not only does the form need all of the elements and their properties when you want to display the form, but they are also required in order to validate the form and re-display the validated form.
I remember seeing this functionality many years ago in a PHP script, which I found is still available. Perhaps you could look at it for ideas. I won't post the link here since the screenshots and script are mostly adult website related and the site is NSFW for the most part, but it is called TGPX by JMBSoft. The 7th of the 8th screenshot on the main product page shows the import process where it lets the user map fields to data, exactly what you are doing.
Hope my advice is helpful, feel free to comment with any questions.
