I'm implementing a web based application in which the help section has "show more faqs" link that will expand the page with more content from the category. The section should pull all faqs question and answers from category which are retrieved from database. Im stuck in finding out as to how to write a html based code to show the remaining contents.
Show more faqs

2 ways to do it:
If you are not comfortable with Ajax: Load all the remaining FAQs during the page load and wrap them in a DIV with hidden class. When the show-more link is clicked, remove the hidden-class from the div.
If you are OK with Ajax: On click of the show-more link, send an Ajax request. It should send across the remaining FAQs. On success of the Ajax-request, append it to the existing FAQs HTML. https://gist.github.com/satyatechsavy/7673942

I am newbie in Apache Jena.I store my RDF-dataset in jena tdb and I serve it in fuseki server.Until now,I am fine.The problem is that I want the output of the SPARQL query to be displayed in a html page.I can't find the way to do this.
If you have ideas,do not hesitate to share them with me!
For part of a page, you need to write a small piece of code that takes a result set and creates the HTML in the format and styling that you want.
You can add an XML stylesheet with "?stylesheet=" but that will get you a whole page.
See this example at www.sparql.org.

I want to crawl an entire website. I am using Simple_html_dom for parsing but the problem is that it takes only one webpage link at a time. I want to provide only start (home page) link and it should crawl and parse all the web pages of that website automatically. Any suggestion how to do this ?
When parsing the DOM of that single page, store all links (within the same domain) in an array. Then, at the end of parsing, check if the array isn't empty. If it isn't, take the first link and do the same.
So something like (code sample written with Python-like syntax, but you can adapt it to PHP easily - mine is rusty).
referenced_links = ['your_initial_page.html']
while referenced_links: # if the array isn't empty...
crawl_dom(referenced_links[0])
referenced_links.pop(0) # remove the first item in that array
def crawl_dom(url):
# download the url, parse the DOM and append all hyperlinks to the array referenced_links

I have 2 different modules in my project
1)Album
2)User
In my album module index action shows the all data of album table.
I want to create the PDF from album table data. How can I configure it and which type of class can I use for PDF?
You need the ZendPdf package, just follow the instructions on the page. Documentation is not ready yet simply because it's not a core module. Documentation will probably follow as soon as all bugs are worked out with the core stuff.
I suggest DomPDF. It creates PDF documents based on html documents. It supports CSS for formatting, renders tables, embeds images and has all the features I have ever needed, and many more. It can even embed javascripts inside PDF which actually works.
I use Zend_View to render HTML document which I then pass to DomPDF to render PDF.

Hi I have a site which has a number of affiliate links, I would like to measure which ones perform best. I could be using the same link say in the sidebar and at the end of each article, and I want to know which is best, the sidebar one, or the one after the article.
How can I do that? Thanks.
In each of the links, try adding an onclick JS snippet with Google Analytics event tracking, or a similar self-created code or code from another analytics suite you use. I do something similar, creating a fake pageview for my download links by adding this in the onclick
_gaq.push(['_trackPageview', '/<?=$idnumber?>/download']);

Is there JavaScript grid component where in read-only mode I would be able to select somehow several rows ( e.g. shift or ctrl with mouse click ) and track/process selected rows.
Well I've used datatables.net previously. Awesome Javascript tables with multiple user selection and server side processing.
jqGrid does this.
