Client works in pharmacy industry.
We print bills for items bought by clients.
General structure of document is the following:
Header
List of items
Footer
Sometimes happens such situation when all list of items fit into N number of pages.
In this case footer is moved to the last page.
Local law forbids such documents, i.e.footer cannot be alone. It needs contain at least one sold position.
Thoughts about implementation:
It would be easy to implement it if I could get the current page during the calling operations like setCellValue or fromArray.
In this case I could check how many lines I still have and if I'm on the new page.
If I 'm on the new page and have zero items then I would add empty line before last position.
I feel it's not possible to get in phpexcel because of the way how Excel works at all.
As for now I have in my mind only one dirty solution:
creating document upon user request
-> storing in somewhere to temporary folder on server -> reading it and checking if document has last page without items , if this is the case I would add empty position and recreate document again (some kind recursion with limited depth.)
But this is too messy solution. Are there any better ways to handle such problem?
Actually if the format is fixed in which you print hopefully (like font type and size, header format, paper size etc) then You can check how many rows are there:
$objPHPExcel->setActiveSheetIndex(0)->getHighestRow();
//if 0 is the sheet you are working on
You can check how many rows does it require to push the footer to a new page. Basically there is a formula to you:
$footerWillBeOnSeparateSheet = $allRowCount % $maximumRowPerPage === $nomberOfRowsWhenFooterGetsOnTheNextPage;
If $footerWillBeOnSeparateSheet is true then you need to add the empty row you mentioned.
I'd use a different approach instead of adding an empty line. Try to separate the last two items and footer for example into a different page in case the value of $footerWillBeOnSeparateSheet is true.
Edit: using getRowHeight() is also an option although it would be hard to maintain the differences of the different templates.

thanks for help with previous PHPWord issue. I have another.
I'm creating documents with tables where each table is basically used as a stylized container for a list of items. For example, in my case i have a collection of legal definitions. Each definition has a code, title, and textual description that appears in a table. So when there's multiple definitions, each definition has its own table, and appears like so:
and so on. Each table isnt really a table, its more i'm kind of hijacking tables to stylize my document. The problem is when I have a long list of items, invariably some of the tables will be split between pages where the top row of the table will be at the very bottom of the page and bottom row of the table will be at the very top of the next page, like so
This is very undesired. Is there any way to tell PHP word that "hey, if this table is going to be split between pages, just put the whole table on the next page" ??
I'm also using PDFmake for making pdf's and it has a pageBreakBefore function that can be used for exactly this purpose. I notice that paragraphs have a pageBreakBefore style which can force each pragraph to appear on a new page, but this isnt what i'm looking for. Is there some way i can maybe get into how PHPWord builds the document to put a conditional test in maybe?
Any input is greatly appreciated thanks.
I had the same problem .... and found the answer today in "normal" MsWord documentation. I found the equivalent in the phpWord doucmentation, tried it and it works:
In your paragraph formats, set 'keepNext' => true
I'm building a web application in PHP, and part of the requirement is that I need to be able to quickly process data on a scanned copy of a fairly simple form, and save it to a database for later retrieval.
Given the following image
how can I identify and assign a database field a value of either true or false (true when it sees a tick, and false otherwise)?
I'm thinking along the following line of implementation:
I will keep two copies of the above image - the first will have ticks shown (as above), and the second will be a "clean" copy of the image with the borders left behind. Comparing between the two images will yield a difference; the difference will return either a value of true or false.
There are drawbacks as far as I can observe of the above implementation. What happens if the user scribbles something in it (as seen above) but it does not mean anything? How do I even ensure that the returned values of true or false are assigned to the appropriate columns in the database?
I don't have any code implementation at this point in time, and I'm not asking for it. Rather, I'm asking for guidance on where to look and how I can efficiently do this.
You may try using OpenCV framework for PHP (https://github.com/mgdm/OpenCV-for-PHP, http://mgdm.net/talks/confoo11/making-php-see.pdf) and use contour detection (or any other classificators) to find signs like "V" and skip false-positives.
You might want to use a PHP OCR library.
I will do thin in a following way: I will divide image into 2x6 grid and count black pixels in each row. If the number n contains in <A;B> then we can assume that row is checked. If someone scratch off an answer then n is larger than B.
So if n is in <A;B> range we can check its pattern - for example common part of the all marked rows because of user's handwriting.
I'm looking to create a poll/form that will allow the user to select a starting 11 for a football game (or soccer if you're American), and then submit it and then see an image of the most popular team selection among the fans (maybe most popular for each position instead of most popular team selection all together).
Ideally I would like the form to have options for formation (4-4-2, 4-3-3, 4-5-1 etc) that would change the layout/inputs on the form (but this is definitely not essential, would just be a nice touch - I would just stick with 4-4-2 otherwise).
My dream idea is that there will be a dashboard on the bottom that had player profile pictures that can be dragged and dropped into their positions; However having simple drop down boxes would work too (as long as a player cant be used twice - which is another stumbling block because you don't want the same player to be in both CB positions.)
Design Concept (Results page would basically be the same just without the bottom dashboard):
I have absolutely no idea how to approach this as it is way more complex than anything I have attempted in the past. (Forgot to mention I would like to be able to reset the results every week or so if possible)
So if someone could let me know if its do-able, and if it is, take me through how to do it step by step or even mock one up for me it would be much appreciated.
Thanks.
It doesn't have to be a form.
Here how you do it:
Create the divs for the squares on the field.
Assign each of them a unique id e.g.
id="square-1"
and give them a common class e.g class="field-square"
Create the divs for the squares outside the field. Give them a common class, and a unique id for each.
When you drop the squares, have a function that extracts the ids when they are dropped.
Then simply post them to your PHP site with jQuery.post()
Update
To extract the ids, in your callback (after you have dropped the square) do something like this:
square_id = square_id.replace('square-', '');
Since you've not assigned number ids (which you should, so that you can easily change the players in future by getting them from a database), you can simply get the ids using $(this).attr('id') in your callback.
Also look up http://api.jquery.com/jQuery.post/
I wouldn't even think about dragging and dropping at this point. Outline what the minimal viable product would be and come up with a set of steps to do that.
Going off the data you provided I would suggest something like this...
1) Build an html form that list simply a list of all the positions and a dropdown of all the possible players that can fill that position.
2) Fill out the form (select the players) and on form submit get the data echo'd as an array.
3) Create the graphic...I see two approaches....(1) server side (GD or Imagick are probably what you are going to want to use) or (2) CSS/html images
Either one will a fine approach....this step should probably be broken into little steps...start with simply displaying a list and an image of the player next to it...
HTML would be
echo "<img src='/images/players".$_POST["position1"]."' alt=''/>";
//(NOTE YOU HAVE TO CLEAN ANY DATA YOU ARE OUTPUTTING PROPERLY)
Imagick would be something like..
$bg = new Imagick("/images/bg.jpg");
$position = new Imagick("/images/players".$_POST["position1"]);
//Second image is put on top of the first
$bg->compositeImage($position, $position->getImageCompose(), 5, 5);
//new image is saved as final.jpg
$bg->writeImage('final.jpg');
I've been racking my brain about an easy way to generate an HTML table with rowspans with PHP that would look like this, numbers indicating each cell's rowspan:
I noticed that there is sort of a pattern in the rowspans if you go from left to right, top to bottom: 1,3,7,1,1,1,1,1,3,1,1. I'm not sure if that matters.
Also, I wonder if it's possible to use any method for the table above for a table like this:
maybe addressing your second example first is easier, but it might be adapted to the first example.
the structure of the tables in html is obtained using the rowspan an colspan properties.
try to picture the table as a closet, the rows as drawers and cells as boxes inside those drawers.
with these properties, u can "merge" the cells throughout rows and/or columns.
my approach would be to set a minimal block with the appearance and data that you need, ie your second example, and write it down in html.
the "php-cycle-the-thing-up" part would require you to use that html "template" in the loop dropping your recordset data in the td portions of the html.
in that way, i think you might get what your looking for.
on the other side, if you need the php to create the table dynamically, and merge the cells automatically in a set pattern, or even ignoring the pattern and simply adapt the structure as the data is coming, it would probably be better to look at the structure from the end.
because of the way that tables are built with html, nesting table-tr-td, building cycles with this look is tricky. have you considered simply nesting divs?
i'm new to stackoverflow, i wanted to comment but by the time i finished this, i couldn't remove the answer nor comment the question, sorry if this didnt quite help you... :S
write down, come up with the recursion formula for the table. you need to come up with the math with the least number ideally ZERO conditional statements.
it's not that hard. for a desktop, i use three columns if it detects a mobile devices, my php automatically switches to 1 or 2 columns depending upon screen size
I've got a client that requires that an article be displayed in two, sometimes three, columns in Joomla. I am fairly sure they won't be happy with having to edit 3 articles for 3 columns so the splitting would have to be done automatically.
I've done something similar before where it'll split a chunk of HTML into n columns, but have no real idea how to accomplish this within Joomla itself.
Any ideas gratefully recieved!
An alternative approach:
Use Javascript to split up the Article in several column in the browser. Here I could imagine a full-automated approach could work.
Advantages (over the first approach):
As Javascript can know, which height the paragraphs actually have in the browser (unlinke PHP), you could find the optimum split more accurately.
This can be implemented in the template php-File: you tell the template to include the js-File. So it could be made context-dependent,E.g.: If the left column is collapsed (because there are no modules in it), tell the JavaScript-File to initialize to 3 columns, else 2 columns.
However, have in mind that it should rest usable for those who have Javascript disabled.
This doesn't seem to be easy.
At first thought this should be an CSS attribute, but if it exists, it is part of CSS 3.0 and as such only understood by modern browsers (if at all). But I didn't find any way to do this in CSS.
So you actually have to modify your HTML code. I would propose the following:
A Button (editor-xtd plugin) that splits the article into several parts, each one for one column, showing a dotted line in the editor box (similar to the "read-more"-Button).
E.g. it inserts in the article: (you will have to define hr.column in /templates/system/css/editor.css).
A (content) plugin that creates the multiple colum-style,
E.g. replacing the hr-Tag with table or floating divs.
This way, it is half-automized, without mangeling in the Joomla! files but only adding to extensions to it.
the CSS 3 rules for multi-columns are:
-column-width
-column-gap
-column-rule
-column-count
with the vendor label (-moz, -webkit) before.
More info at http://www.css3.info/preview/multi-column-layout/
I would use css and tell the people with Explorer to change browser! (i'm jocking of course)
Otherwise javascript is the way like said before. This script should do (not tested) http://13thparallel.com/archive/column-script/
This should be done through the template, some PHP coding is involved.
One of our clients asked us to do the exact same thing before, and we have done it through template. Note that for very small articles we increased the font in order to split the article into 3 columns.
