I was playing with something the otherday that might be whhat you'r after.
It just displays a (dynamically generated, in this simple example) table, and allows editing by just double-clicking a cell.

I'm not a fan of just writing HTML with javascript e.g. str += '</tr>';
I would rather use the document.createElement( [tag name] ); function. I'm also a huge fan of jQuery.
Below is how I would go about creating a table in Javascript.
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en">
<head>
<title>Create Table</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
function createTable(rows, columns, newId, parent)
{
$(parent)
.append(
$(document.createElement('table'))
.attr('id' , newId)
);
for (var rowNumber = 1; rowNumber <= rows; rowNumber++)
{
$('#' + newId)
.append(
$(document.createElement('tr'))
.attr('class', (rowNumber % 2 == 0) ? 'even' : 'odd')
);
for (var columnNumber = 1; columnNumber <= columns; columnNumber++)
{
$('#' + newId + ' tr:last-child')
.append(
$(document.createElement('td'))
.html('(' + columnNumber + ', ' + rowNumber + ')')
);
}
}
}
</script>
</head>
<body onload="createTable(10, 10, 'newTable', '#parent');">
<div id="parent"></div>
</body>
</html>

Hi all,
I want to create a PHP IDE.How can i do it ?
Thanks in advance.......

Pick a language - java/c++/C# are probably best, but you could try php & tk (but it's painful). Learn how to build windows and forms with it.
Plan your application on paper n get coding.
I suggest looking at some coding tutorials first. c# and wpf are probably a good starting point.

Hi,
I am a windows programmer with more than 10 years experrience and am newly venturing into the world of web development (specifically PHP). I would like to know what most PHP developers do to create visual content i.e. do they use a HTML editor like Frontpage or Dreamweaver and intersperse the generated code with PHP code or do they code everything by hand?
I posted the same question in another forum and got the reply that PHP is mostly coded by hand. That appears a bit daunting since creating a single page could involve writing more than a thousand lines of HTML code. I can't believe people are still hand coding thousands of lines of code in this age of visual development tools. Is there some easy way around this?
|

Visual development tools can help - but the problem is if you know your code then writing it by hand is a lot quicker - also there isn't a program that can write good php code for you. Aptana Studio can help you write class getter and setters in code and a few other programs have similar useful features but that's about it. DW does have a useful quick css properties editor.
If you have a good coloured coded IDE with good intellisense (code helper) then it will always be quicker to code by hand.
The good thing with php is you can reuse your code by using includes, functions and classes. So you can make a header and footer for your website once and just reference it in the other files (much the same as calling functions in windows programmed classes). You can process and validate form data and work with cookies and session variables. And that's just the start, PHP also has a multitude of other functions.
You should try to build yourself a php code library from the start and keep upgrading the different elements.
Personally, I create everything except images in DW. Once you know the keyboard shortcuts it's a breeze. I use FileZilla FTP instead of DW FTP.
I also install a copy of notepad++ on all my clients servers - small footprint but has code colouring for a range of file types.

I've been coding for a long time, and I still do quite a bit of work in a text editor (outside of an IDE) for languages such as PHP. Find a tool that recognizes various languages - that will at least get you past design-time errors. I like to use programmers notepad. It recognizes PHP, javascript, HTML, css, etc.. Any similar tool will work.
Try to write your code modularly with the idea that it will be used in multiple projects. After a while you will find that you've written a nice set of libraries (such as blocks of PHP code that can be 'included') that can be arranged within your project like components. At that point you won't be writing so much code anymore as much as you will be simply arranging the components to build larger applications.
Good luck,
Rob

A few days ago I noticed that, when updates are available, the usual icon in the system tray doesn't appear.
Everything else works perfectly, whether I update through system settings, or through the console... I just don't get a notification when an update is available.
Any idea why?
Got it. I was missing some python bindings.
Where it seems there are only borderlines, Where others turn and sigh, You shall rise!

hi experts i want to build an server

This is a very late reply. Let somebody like me get benefit. (i searched a lot and could not even get a tail for these).
You want to setup a server by using PHP?
If i were to do so then i will choose C/C++ 32bit to do so.
You need to know about sockets. The simple concept of client and server. and some basic idea of an existing client server protocol. better if HTTP.

mysql_select_db("lab") or die("Database Missing");
}
?>

Hi,
Just a note, that you should edit your post and put your code in PRE tags, because it will make your code more readable as it can preserve formatting and uses a mono-space font therefore it will make your post more useful.
function example($e)
{
echo $e;
}
Can you see how much nicer that is to read?
ps. PRE tags also support some syntax highlighting.
If at first you don't succeed, you're not Chuck Norris.

How to refresh iframe in php ?
I have 4 iframe in my php and want to refresh all.Example:-
<div id="l1" style="position:absolute;left:50px;top:120px;width:450px;height:140px;z-index:35" align="left"><iframe frameborder=0 src="http://ck.com/ker.php?scrip=echo $us" width=412 height=160</frame>/div>
|
|
|
|

I'm very confused. Do you want to refresh the iframe's during run-time i.e. after the page has loaded? Because I do not see how you can do that with PHP, it would have to be Javascript.
The only possible time you can use PHP is before the page has loaded, in which case it would be pointless as the iframe would be loaded anyway. Everything after the page load has to be done with Javascript.
Here is how to refresh the iframe in Javascript:
document.getElementById('iframe1').contentWindow.location.reload(true);
If at first you don't succeed, you're not Chuck Norris.

Thanks for your help.I want to refresh iframe after loading page and after every 1 minute.If it is not possible in php then can you tell how to insert java script function in php for refreshing iframe.If you can try to give me a very short example.
Thank You

udch wrote: If it is not possible in php then can you tell how to insert java script function in php for refreshing iframe.
Your statement shows a clear lack of understanding about how HTML, PHP and Javascript work.
In the below example you can see how to use PHP with HTML correctly. You can see that the HTML tags are not written in PHP. The only part of this page that is affected by PHP is the body which will have 'Hello World!!' written in it.
Also see how the Javascript is in the <script></script> tags. Make sure you give the type of the script block which in this case will be text/javascript.
Your Javascript functions will now go in the script tags, as shown. Notice that in the function refreshIframes() there is a setTimeout() function which calls the function given as the first parameter ('refreshIframes()' in this case) and the number of milliseconds to wait for it to call as the second parameter (60000 in this case [60 seconds]).
Please also note that onload="refreshIframes()" is in the body tag, this calls the refreshIframes() function once the page has loaded.
<html>
<head>
<title>Hello World</title>
<script type="text/javascript">
function refreshIframes()
{
setTimeout('refreshIframes()', 60000);
}
</script>
</head>
<body onload="refreshIframes()">
<?
echo 'Hello world!!';
?>
<!-- INSERT IFRAME HERE! -->
</body>
</html>
If at first you don't succeed, you're not Chuck Norris.
