Hi friends i am working on JQ-GRID. I want to show Image in specific column, But i don't know how to attach image in JQ-GRID. Can anybody help me or please send me some links, thanks
jqgrid is a feature monster. I tell this everybody who asks about it.
When jqgrid loads, a function is called which actually gets the data you want to display.
This is normally an ajax call to your php. As a result set of this function, you can just use xml or json.
I prefer json, so I build my result array and do a echo json_encode($myarray)
jQuery("#your_grid_id").jqGrid({ url : '/ajax/getjqgriddata.php'})
Now displaying pictures, there are different ways you can do that. You can either generate a <img src="wherever/mypicture1.png"></img>-link and hand it over in your result, or encode your picture binary data with base64 and deliver it with your result.
A more addvanced way is to use an so called formatter and just returning a id for the image.
This depends on you, but I would suggest to get confident with jqgrid, experiment with returning -links to get a feeling how jqgrid works.
There is plenty of good documentation at:

Just take a look at it.

i have been assigned to integrate an API in a blog.
API URL:http://www.ask-oracle.com/charts/api.php?dt=2015-10-19T08%3A48%3A32%2B05%3A30
I am able to get the data using
$data = file_get_contents('http://www.ask-oracle.com/charts/api.php?dt=' .$date .'T08%3A48%3A32%2B05%3A30');
But not able to organize it properly.
It returned JSON array, i need your help in getting out the data and show properly(organized way) in my blog.
Please help me, how i can do it.
I will be very thankful to you if you provide me code(in html or php) also.
This is up to you to decide how to organize this. As #steve suggested it, you should convert the JSON stream to a PHP object, and then transform it to HTML to "organize" it for humans who are not able to read JSON. It will surely also involve CSS.
If somebody asked you this work but didn't gave more informations about how to display it and you have no idea about how to do it, you should maybe ask for more precise specifications before starting the work.
Note that saying that JSON is not properly organized is not exact. JSON is a structured data notation.
In PHP, I was wondering how to retrieve specific data from a google search. For example if I wanted to retrieve the price on https://www.google.com/#q=ps3&tbm=shop for the first result. I have experimented with curl and domdocs and am not going any where.
The simplest way to get the contents of a webpage in PHP is to use the file_get_contents function.

Once you have the data, you'll need to parse it. There have been plenty of great articles about how to approach this, so I'm not going to repeat them. Here's a link to a good one:

I have to list the table entries from mysql in my iPhone app when a button is pressed. I am able to do it properly but it is just not the way I want it. I am using a PHP script to send Xcode what has to be printed.
First, I tried doing it using HTML table, but I didn't like the way it was printed with cells. Next I tried printing plain text by giving spaces(between columns) and \n for every new row. I used NSURL and loaded the webView to the iPhone. Looks good on browser but the same is not preserved when the iPhone tries to open it.
Is there a good way to do this? So I can just list the table entries without having to go through the traditional HTML table or any other idea is welcome.
Also, please try to be easily understood, as I am new to Obj-C, and PHP as well.
Thanks!!
Any thoughts on how I can do this in a UITableView..?? Do I have to return a string with component separation characters and fill in the tableView?
Output the results encoded in JSON. Send an a(sync) request to the server using NSURLConnection or using a third-party library such as AFNetworking. Parse the JSON using NSJSONSerialization, turning the results into an array/dictionary depending on the contents. Then parse the results into the UITableViewCell. It may be easier to subclass the cell so that you include the data that you'd like to use.
To encode the results from the database into JSON, you can use the method json_encode().
I am new to jquery and JSON and i am bit confused as what is best and professional approach.
Suppose i have the long list of data like song name , artist , author etc.
Now i dynamically want to dislay records from database.
I have two options
Here i return the full html and update that with the target element
Second is to retrive the JSON data full of songs info and then build that html with javascript and populate it.
I want to know which approach is better and used by high traffic sites
Second is better because of data size being sent over the network. Reducing it will improve the performance.
Write a function that will use JSON data to generate HTML elements.
If you're running a high traffic site with lots of data then the second solution, using JSON does have the advantage of only giving you the raw data and relying on the browser to generate the HTML to display the data.
Personally I would need to hear some really convincing arguments for using the first option at all.
I'm trying to parse information from fonefinder.net. I was trying to use simplexmlload_file, but couldn't get the page to load successfully.
Now, I'm looking into Curl. But I'm not sure if this will work either.
I basically just want to take the html from the fonefinder page, and parse it to get phone carrier and city.
Is that possible? How?
SimpleXML will only work if the HTML is formatted correctly - and that is rarely the case ;)
You could do a simple cURL call to fetch the data and the easiest thing would probably be using a regular expression to get the information you need.
The solution however is not easy to supply you with, with nothing to go on. But this was an idea.
I Recommend using:
http://www.de.php.net/manual/en/function.file-get-contents.php to get the document
http://www.php.net/manual/en/domdocument.loadhtml.php to load it
http://www.php.net/manual/en/class.domxpath.php to get the information from it
Or use the search function here, that question must have been asked over and over, for example PHP: Fetch content from a html page using xpath()
