I have a page which has an iframe embed of an external page. I want to find zip code
Here is my iframe:
<iframe src="http://mortgagerates.icanbuy.com/?zip=" width="1020" height="1200">
http://mortgagerates.icanbuy.com/?zip=10458 (Main Site )
But i want i frame and my browser url same below:
http://www.mysite.com/?zip=10458 (I want something like that)
Is this possible in wordpress? how?

Please check it.. I hope work it...
<iframe src="http://mortgagerates.icanbuy.com/?zip" width="1020" height="1200" class="iframe-wrapper">
And add this jQuery. Thats It!
<script type="text/javascript">
$(function() {
var search = window.location.search;
search = search.replace("?","&");
$(".iframe-wrapper").attr("src", $(".iframe-wrapper").attr("src")+search);
});
</script>

This is ajax page. you want to use ajax.

you need to pass your zipcode into city=10458. its return json encoded format. you simply parse this into your design.

How to preload a web page using external preloader?

I have a simple HTML page that has a large image as a full screen background; I called this page index2.html.
I want to create another page called index.html which will preload index2.html fully, and then direct the user to it. However, all the preloader solutions that I've found on internet are based on a single HTML page.
How can I accomplish this? Any help would be appreciated.

You can cause the browser to cache the image by loading it on index.html as a 1 pixel image
<img src="/index2-background-image.jpg" alt="" width="1" height="1" />
Alternatively you could load the content from index2.html using jQuery like so:
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script type="text/javascript">
jQuery().ready(function () {
$.get('index2.html', function(data) {
jQuery("#index2content").html(data);
});
});
</script>
<div id="index2content"></div>

loading html code with html

I want javascript to load a html code so it can be embedded in a page, all I get is the raw html code without being compiled.
<script>
document.write('http://www.example.com/index.php?title=Media:Object4&action=raw&ctype=html')
</script>
It contains the html coding inside and I want it to embed in pages so I can share with other websites.

Are you trying to get the HTML from that URL and embed it in the page? JavaScript can't do that for security reasons, but if you're using PHP server-side you can use:
echo file_get_contents("http://..........");
Or you can use an iframe:
<iframe src="http://........" />

The easiest way to make this work, sort of, is by using <iframe>:
<iframe src="http://www.example.com/index.php?title=Media:Object4&action=raw&ctype=html"></iframe>
If you want to load it inside a particular container, you have to perform a web request using JavaScript; jQuery example:
<div id="container"></div>
<script>
$('#container').load('http://www.example.com/index.php?title=Media:Object4&action=raw&ctype=html');
</script>
If the remote URL is not in the same domain, you need to use a proxy:
<script>
$('#container').load('/path/to/myproxy.php', {
url: 'http://www.example.com/index.php?title=Media:Object4&action=raw&ctype=html'
});
</script>
Then your PHP code could look like:
<?php
if (parse_url($_POST['url'], PHP_URL_HOST) === 'www.example.com') {
echo file_get_contents($_POST['url']);
}

document.write - adds text to the document - it does not fetch documents from the web.
However, you can use the object tag.
It should look something like that:
<object type="text/html" data="http://www.example.com/index.php?title=Media:Object4&action=raw&ctype=html" style="width:100%; height:100%"></object>
Additionally, if the page that you are fetching is on the same domain, you can use AJAX to fetch it.

Insert javascript widget on one page of Drupal site

I have a javascript widget that can be inserted on an a plain-old html page like this:
<html>
<head>
<script type='text/javascript' src="http://example.com/widget.js"></script>
</head>
<body>
<script type='text/javascript'>
//<![CDATA[
try{ widget_constructor('key',500,400); }
catch(e){ alert(e.message); }
//]]>
</script>
</body>
</html>
I would like to insert this javascript on one page of a Drupal 6 site (not every page).
This is what I have tried so far to get the script tag in the HEAD:
I set the Full HTML input format to allow php.
For the Drupal page, I set the input format to Full HTML
I then added this to the top of the body of my Drupal page:
<?php
drupal_set_html_head('<script type="text/javascript" src="http://example.com/widget.js"> </script>');
?>
But Drupal doesn't parse the php and instead prints this at the top of the page:
<?php drupal_set_html_head(''); ?>
Any suggestions as to how I can do this?

#Jeff: You should not really reconsider that. Using the PHP Filter is generally a bad idea as it potentially opens security holes. (In case someone would gain access to your user account or you have a misconfiguration in your settings this is a direct path to compromising the whole server)
I would rather propose to add js via the template.php of your theme. Also the right method to use is drupal_add_js with the option inline:
http://api.drupal.org/api/drupal/includes--common.inc/function/drupal_add_js/6
Here are some further reads on how to use it:

I'm not too familiar with Drupal so this answer merely gets around your widget not loading without actually answering the question why that PHP block isn't being parsed as PHP.
You don't need to call the <script> tag inside the <head>. You can just place that line right above the <script> tag that calls the widget constructor.
<html>
<head>
</head>
<body>
<script type='text/javascript' src="http://example.com/widget.js"></script>
<script type='text/javascript'>
//<![CDATA[
try{ widget_constructor('key',500,400); }
catch(e){ alert(e.message); }
//]]>
</script>
</body>
</html>

After writing that all out, I figured out the problem...
The full html input format has an HTML corrector filter turned on by default, and that filter appears to have caused problems with the PHP code. Reordering the filters to put the PHP evaluator first fixed the problem.

Show image while page is loading

My webpage is using some api's together and the total process time for the page to load is around 8 seconds. I want to show a page loading image while the page is loading. Could be like the whole page is dimmed out and an image is shown which represents the page loading and once the page loads i want to go back to my page. How can i show this functionality in a php website?
Little more info:
The page is not even loading until all the visualizations in the page have completely loaded. In other words, the URL of the page is not even changing as soon as the link is clicked. As soon as the link is changing, the webpage is loaded, so any solution or reason why this is happening?
I am actually using GAPI class to get Google analytics feed and using google visualization javascript api to show the images. I am using multiple GAPI for different data parameter calls since one certain combinations wont work in one command...
a sample:
$pie->requestReportData(ga_profile_id,array('browser'),array('pageviews'),'-pageviews','',$start_date,$end_date,$start_index=1,$max_results=50);
$ga->requestReportData(ga_profile_id,array('date'),array('visits','visitors'),'date','',$start_date,$end_date,$start_index=1,$max_results=50);
The values returned are stored in an array and used for google visualization api.
Each of this is stored in seperate files and i am calling them using include ();

Use jQuery...
<script type="text/javascript" src="http://jqueryjs.googlecode.com/files/jquery-1.3.2.min.js"></script>
<script type="text/javascript">
$(document).ready(function()
{
$("#loading").hide();
});
</script>
Right below body start tag put...
<img id="loading" alt="" src="ajax.gif"/>
You can create some ajax loading gifs here... http://www.ajaxload.info/
Add this CSS...
#loading{position:fixed;top:50%;left:50%;z-index:1104;}
Update
Replace with this JS code, leave the googlecode line.
<script type="text/javascript">
$(document).ready(function()
{
$("#info").load("info.php");
$("#linechart").load("linechart.php");
$("#piechart").load("piechart.php");
$("#loading").hide();
});
</script>
HTML:
<div id="#info"></div>
<div id="#linechart"></div>
<div id="#piechart"></div>
Hope it helps.

Use the following function:
<script type="text/javascript" src="http://jqueryjs.googlecode.com/files/jquery-1.3.2.min.js"></script>
<script type="text/javascript">
$(window).load(function()
{
$("#loading").hide();
});
</script>

Well, there are few issues on this path.
First of all, you output html to show loading screen, and run flush() command.
Ensure you do not have any gzip compression in php or apache, as content would not be sent to the browser.
Then, you have to pray that browser would be smart enough to render it and not wait for xxx kb of data till next render.
Anyway, I would invest more time in optimization. Or do a light main page and do the rest of functionality via AJAX.

This is not actually php.
But you can do as follows:
Add the following to the head section:
<script type="text/javascript" language="javascript">
function wait()
{
if(document.getElementById)
{
document.getElementById('waitpage').style.visibility='hidden';
}
else
{
if(document.layers)
{
document.waitpage.visibility = 'hidden';
}
else
{
document.all.waitpage.style.visibility = 'hidden';
}
}
}
</script>
Change the <body> to <body onLoad="wait();">
and add the following in the beginning of body section:
<div id="waitpage" style="left:0px; top:0px; position:absolute; layer-background-color:white; height:100%; width:100%;">
<table width="100%" height="100%">
<tr>
<td><img src="path-to-image"/></td>
</tr>
</table>
</div>
