I have permission to use the table with a link to its inclusion on its website, where the name will be redirected to the landing page. However, the website owner is not able to say whether and how to modify the address of the page to display all the records in the table at once without paging.
It is even possible? If so, what you need to use GET?
http://www.newconnect.pl/?page=1045&id_firm=&id_tr=&ncc_index=ESC&ph_main_content_order=&ph_main_content_order_type=&ph_main_content_offset=0
Currently on one page displays only 20 records.
First of all ask site owner if it has some API to share data. It would be much easier.
If not you always can write a crawler and move from page to page, to get data. I strongly recommend to use Simple HTML DOM Parser to get website content.

I am making a site for someone who wants to embed their own youtube links. I am relatively new to web development and this is my first commission so I was wondering how I could hand over the site to the client and allow them to upload their links without me having to edit the mark up for him.
I understand how to use an '<iframe' youtube link in HTML to embed videos and am considering creating a database using PHPmyadmin that uses a form that the client can fill in with the iframe link whenever he needs to embed a new video.
I understand if that sounds like a convoluted way of doing this but if anyone knows a more intuitive way to solve this issue please let me know :)
I think it can be done using a database, may be MySQL, to keep it simple and a simple backend programming language, PHP would do.
You create an admin page just to collect the URLs from the admin. A nice little login page which stores admin username and password in a table. And you can use this module to assign roles to admin, add an admin or delete one.
Inside the module created above, create a page with a form to fetch and store URLs in the database. If you are going to categorize the videos, use suitable columns. Say you are going to categorize based on the genre and length, the table in your database should contain genre and length so that you can use them as filters later on.
Use cookies to create session for the admin. This is to avoid redirecting him to the login page after every single reload.
For all other user who is not admin, do not redirect to the admin page. Redirect them to a common page where they can search and enjoy the videos that the admin has added.
Again, like mentioned in many comments above, wordpress does it all. You have an option to use it too, it's free.
What I am trying to do is to make something similar to what I see all the time on almost any website. The button that says Share to facebook. The goal for me is to let my guests share the item they are viewing in my store (Ran on prestashop) on their blog I run (Running on Oxwall).
The goal is for the button to not only link to a blog post submission webpage but to already have the subject line filled out with the item they are sharing's name and the blog post to display the information about the item. I would like to try and do all this using PHP. I am not sure how to go about doing it but I am sure that I could pass the value. Please note that I can mod BOTH the blog site and the shop as I run both and want to connect them.
As an extra bonus I am also running a forum using phpbb3 if I could do the same thing but onto that as well I would greatly thank you. I am trying to interlink everything into one big network. I know its not an easy task but I am sure there is an easy way to pass data onto the other site so that this can be done.
Facebook a 2 tools to get items informations in the page, it parses the page looking for the most common tags and it uses OpenGraph.
You can also provide product informations in the head of your page (between head tags), then blog side, you retrieve only the contents and parse it as XML.
I advise you to cache this data to avoid useless connections between websites and awful overloads while parsing.
You can use your own specifications, Open Graph or another standard, but i advise to use a standard.
Please indulge my simplistic example:
Let's say I have 1 million pages on my site. Each page has an ID number (i.e. www.mysite.com/product.php?id=1 .... upto id=1,000,000
I want to make a page that allows users to email themselves the link to the page (or email a friend). This page is also dynamic and comes from the product.php, so like this:
www.mysite.com/email_a_friend.php?id=1 .... upto id=1,000,000
Imagine I do this and now google wants to crawl 2 million pages instead of 1 million. This seems pointless since the page doesn't have anything of any value on the email page. Also, consider that the email page would actually be a pop-up window on the product.php page.
What is the best way to handle this?
Should I block it (email_a_friend.php) through a robots.txt file?
Or should I perhaps used java or something else for the link that google would ignore anyway?
Thanks!!
If I'm understanding your question correctly, you have an e-commerce site and want to implement a share button for a particular product. What you don't want to happen is have google index the page that the share button goes to.
If that's the case, just add a rel="nofollow" to the link in your php that generates the link and you should have no problem.
Here is a google help article that explains how google does not follow links with the nofollow attribute: http://support.google.com/webmasters/bin/answer.py?hl=en&answer=96569
Let's say I have a URL: http://example.com/person/list
This website will display a list of people. The list of people get very long, so eventually I build in pagination. Let's say 10 people per page. The URL looks something like this:
http://example.com/person/list?page=2
If I click the next page link, I will be taken to page 3:
http://example.com/person/list?page=3
This is good because if I copy and paste the URL to a friend, she will be directed to page 3 immediately.
Let's say that I now incorporate AJAX, and the page requests are ajax calls using jQuery. The original URL is http://example.com/person/list and when a user clicks on the next page link, the URL in the address bar doesn't change.
This is bad because if I'm on page 3, the URL in the address bar doesn't reflect this anymore.
There are multiple jQuery history plugins which will change the URL, however, these will ONLY change the portion of the URL which is after the hash mark #. Information after the hash mark is not sent to the server.
If I'm using a history plugin, the URL can be changed to http://example.com/person/list#page=2
My problem with this approach is: If someone copies and pastes this URL to a friend, when the friend requests this URL, I have no idea which page the user is intending to look at. Therefore, my best approach is to load all of the people entries onto the page, and have javascript select which page to display based on the information after the hash mark. This is a problem because I started to paginate the pages to reduce the amount of information being pulled back from the server in the first place!
What options do I have, such that I can have the back button be usable with Ajax, but also have bookmarkable links which do not require me to get all info from the server.
As I recently learned from my question you have to check the hash-part of the url after the 'friend' opened the link and fetch the content using ajax.
Or you can rewrite it on the server-side to http://example.com/person/list?page=2
You could not list anything until the page loads and then have ajax load the appropriate page.
Another option would be to load the first page as normal and then have javascript check the page hash to load the appropriate page.
For very small loads (and I assume loading 10 people is 'fast'), the second option is probably the best as it shouldn't cause too much disruption of the UI.
Option one has a downside as far as SEO goes, as search engines won't index the content if it's not loaded.
I am creating a classifieds website.
Im storing all ads in mysql database, in different tables.
Is it possible to find these ads somehow, from googles search engine?
Is it possible to create meta information about each ad so that google finds them?
How does major companies do this?
I have thought about auto-generating a html-page for each ad inserted, but 500thousand auto-generated html pages doesn't really sound that good of a solution!
Any thoughts and idéas?
UPDATE:
Here is my basic website so far:
(ALL PHP BASED)
I have a search engine which searches database for records.
After finding and displaying search results, you can click on a result ('ad') and then PHP fetches info from the database and displays it, simple!
In the 'put ad' section of my site, you can put your own ad into a mysql database.
I need to know how I should make google find ads in my website also, as I dont think google-crawler can search my database just because users can.
Please explain your answers more thoroughly so that I understand fully how this works!
Thank you
Google doesn't find database records. Google finds web pages. If you want your classifieds to be found then they'll need to be on a Web page of some kind. You can help this process by giving Google a site map/index of all your classifieds.
I suggest you take a look at Google Basics and Creating and submitting SitemapsPrint
. Basically the idea is to spoon feed Google every URL you want Google to find. So if your reference your classifieds this way:
http://www.mysite.com/classified?id=1234
then you create a list of every URL required to find every classified and yes this might be hundreds of thousands or even millions.
The above assumes a single classified per page. You can of course put 5, 10, 50 or 100 on a single page and then create a smaller set of URLs for Google to crawl.
Whatever you do however remember this: your sitemap should reflect how your site is used. Every URL Google finds (or you give it) will appear in the index. So don't give Google a URL that a user couldn't reach by using the site normally or that you don't want a user to use.
So while 50 classifieds per page might mean less requests from Google, if that's not how you want users to use your site (or a view you want to provide) then you'll have to do it some other way.
Just remember: Google indexes Web pages not data.
How would you normally access these classifieds? You're not just keeping them locked up in the database, are you?
Google sees your website like any other visitor would see your website. If you have a normal database-driven site, there's some unique URL for each classified where it it displayed. If there's a link to it somewhere, Google will find it.
If you want Google to index your site, you need to put all your pages on the web and link between them.
You do not have to auto-generate a static HTML page for everything, all pages can be dynamically created (JSP, ASP, PHP, what have you), but they need to be accessible for a web crawler.
Google can find you no matter where you try to hide. Even if you can somehow fit yourself into a mysql table. Because they're Google. :-D
Seriously, though, they use a bot to periodically spider your site so you mostly just need to make the data in your database available as web pages on your site, and make your site bot-friendly (use an appropriate robots.txt file, provide a search engine-friendly site map, etc.) You need to make sure they can find your site, so make sure it's linked to by other sites -- preferably sites with lots of traffic.
If your site only displays specific results in response to search terms you'll have a harder time. You may want to make full lists of the records available for people without search terms (paged appropriately if you have lots of data).
First Create a PHP file that pulls the index plus human readable reference for all records.
That is your main page broken out into categories (like in the case of Craigslist.com - by Country and State).
Then each category link feeds back to the php script the selected value regardless of level(s) finally reaching the ad itself.
So, If a category is selected which contains more categories (like states contain cities) Then display the next list of categories. Else display the list of ads for that city.
This will give Google.com a way to index a site (aka mysql db) dynamically with out creating static content for the millions (billions or trillions) of records involved.
This is Just an idea of how to get Google.com to index a database.
