Hello we have a non profit application built in Google App Engine for Java.
This application allows people to register as Blood Donors on our system.
As a result we want to email them their print ready e-BloodDonor cards.
What is the way to create such cards where we can define the design of the card and contents are filled dynamically based on registered data?
Please advise
You could create the layout in HTML, just like a normal view in your app, and then email them the link to that page to print it out. You could also go the much-more-complex route of generating PDFs or images for each user. PDFBox by Apache is pretty good for PDF generation.
I'd really recommend the HTML route, though, if it works for you. In my experience, it's much easier to do HTML layouts than it is to program PDF layouts in Java.

I have an e-commerce react app, so as you know every product has at least three or four images, so to show the image of product in my website i created a folder with a name of " images " inside the public folder so everytime i want to show images of a specific product i can get and show them very simply and for Now this is very very awesome.
The Problem:
as we know each e-commerce website should have an admin where he can publish new products and upload new images, so by the time may be i will have thousands of images in my website.
Question
what is the best practice to store images of my react app ?
do i need to use third party like AWS or Firebase ?
Thank you.
Storing images in the code-base assets folder is not the best option for large number of images. Handling updates, inserts is a big problem. So you have the following options.
Options: Cloud/On Premises
You may store in the cloud like AWS S3
If you want to store on premises, you may store in MongoDB Grids
or even on the File System with file-path stored in the database.
Step Ahead
But going ahead you might need responsive images according to the image placeholder. Example for an image you might need thumbnails of different sizes lets say for listing pages, android apps, iOS apps.You might also need to compress the images in case they are heavy for web purpose.
In that case you may choose to store the images in the desired
resolutions.For this you'll have to store multiple versions on an image. For example product1/original.jpg, product1/compressed.jpg, product1/300x300.jpg etc
You may resize/crop the images on the fly. If you want to write your resizing systems you may write ImageMagick/vips/PIL etc based code.You may try to search for readymade nginx based plugins to server responsive images.
If you do not want to do this resizing stuff yourself you may use image storage services like imgix,cloudinary,akamai that provides CDN + image manipulations.Some of these provide storage+manipulation while some only manipulation.
I'm looking for a way to create a search box in wordpress, where visitors can search a number from the database. Is this possible? I have several package numbers in my database. I want to give my visitors the ability to search for their package number and request the information that comes with the number.
What you want to do can be done.
I suggest a different approach than using wp-exec. (I just looked at wp-exec website, and that plugin was created for WordPress 1.5, which means it hasn't been updated in about 5 years).
The content you want to display exists entirely outside of WordPress. I suggest you use a custom page template - see
http://codex.wordpress.org/Pages#Creating_Your_Own_Page_Templates
In this case you would not use WordPress posts or pages or custom post types. On the custom page template you would write (or have written if you don't have the knowhow to do it yourself) PHP code to extract the info from the database and display it on a page.
For pages like that you would be using WordPress only as a container within which to display the results - they custom page would appear in the site Nav, The page of results would use the site's theme to display so it looks like the rest of the site.
But the code to display from the database would not use the WordPress loop. It would be PHP / MySQL data retrieval and display code.
I really doubt you will find a plugin that lets you display results from an external database, formatted the way you want them to appear. The reason is every external database is different, has different tables and table structures. And no two sites will want the external data visually displayed in the same way. So there is little generalization to encapsulate in a plugin as everyone wants it different.
I've created pages on some sites along the lines of what you want to do thus I know it can be done. But it requires writing custom code.
Is it possible to connect a highslide gallery to an external database that can load in the image/path/etc as well as the caption/text assoicated with that image into a website. Thereby eliminating the need to house the images, thumbs and html code on the page referencing the images specifically?
Yes, serving the images and captions etc. in a database is standard procedure for web developers working with server based technologies like PHP/MySQL, Node.js or ASP.NET. I won't go in detail here, but the idea is to make the server side language print HTML and JavaScript for the client, for example by printing image tags including the image file path and caption text. To learn about this in detail, you need to know the basics in for example PHP, which you can pick up in online resources on the matter.
Any idea, how can we create already running website to Mobile Website?
Are there, ready made plug-ins / components available ?
I've found some like wapple.net however it is paid one, which is not feasible for client's budget.
I have found, XML creations is pretty easy in CakePHP, though your ideas would be appreciated.
Kindly share more details on the same !
Regards,
i dont think that you'll find a plugin that will transform your website for mobile. because there are too many decisions to make when creating a mobile web, for me it's like creating a completly different website with only the necessary information that your website has..
But maybe there are components that might help you with the small taks (like detecting the user agent and stuff).. here you can read two good articles about creating a mobile website:
http://www.smashingmagazine.com/2010/11/03/how-to-build-a-mobile-website/
http://www.smashingmagazine.com/2009/01/13/mobile-web-design-trends-2009/
There's also a few JS frameworks that will help you with the interaction with the user, i've only used Sencha touch..
But my guess is that you'll have to adapt/create "manually" the css, html and js for mobile, and I don't think that there's a magical tool to do that, you'll have to do it yourself (or pay someone to do it =D)
Hope this helps, Good Luck!

CakePHP v2.2.1 Solution (+ Cookies to persist mobile/desktop/other layout)
In a nutshell:
Lets you setup mobile layouts /Views/Layouts/mobile/default.ctp
Mobile views /Views/Pages/mobile/home.ctp
Sets a template variable $is_mobile
Lets you force a specific layout ?forcedLayout=desktop, and remembers this in a COOKIE
If no layout is forced it uses CakePHP's User-Agent detection to make the decision $this->request->is('mobile')
If no ../mobile/ layout or view file exists then it falls back to the default layout or view.
Typically with cakephp you want to create a separate view layout for mobile viewing. The app controller should change the default view layout to the mobile one when detecting a mobile browser.
Your mobile view layout should be made by you, only you know what data on your site is important and what is not (aka, what should be removed /kept for mobile viewing) Also your mobile layout can use alternate CSS and only load the elements you want.
To learn more about creating views in cakephp see the cookbook:
i am playing around with qooxdoo lately, it is really interresting, but all the examples build up everything from a blank html page, which would end in being the whole site not indexable from a search engine.
Is there a way to build qooxdoo widgets from html source... most important for me would be a table, so i put html code of the table in the page and tell qooxdoo to build the table from the html source, is this possible?
A general approach would be to to make all your "pages" accessible via URLs styled like example.com/#page=x. Then configure your web-server to rewrite to those URLs, so that for example page/x.html is mapped to #page=x. Finally, submit an XML-Sitemap to Google and other search engines.
