Allowing client to update 'banner' area on home page

[rasstag]

Gentlemen… (…and Ladies, of course),

I maintain a small web site for a friend, occasionally I am asked to add a banner/notice on the home page to reflect some issue that he wishes to broadcast.

He has asked if there is a way that he could enter in the ‘banner message’ so that he would not have to send email to me to have me do it.

The home page is a rather simple HTML page (index.htm) and the ‘banner area’ is as follows:

<div class="banner" id="banner">

<!-- <p>We will be out of the shop until Feb. 21st . We will be online daily & welcome your orders for shipment as soon as we return.</p>-->

</div>

I have written some .php code which allows the user to enter the banner message and it will write it to a text file on the server.

My challenge is, since I’m still self learning .php and javascripting etc… I haven’t found a clean way of having the home page read the content of the banner file and write it to the screen for the user to see.

Any thoughts on how this could be implemented?

Regards,

Well, one way is to use javascript(ajax). So, i created an example of how it could be done:

<div id="banner"></div>

<script type="text/javascript">


if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
	xmlhttp = new XMLHttpRequest();
}
else
{// code for IE6, IE5
	xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
}

//url to file with banner-code.
bannercodeurl = "http://www.example.com/bannercode.html";

xmlhttp.onreadystatechange = function()
{
	if (xmlhttp.readyState == 4 && xmlhttp.status == 200)
	{
		document.getElementById("banner").innerHTML = xmlhttp.responseText;
	}
}
xmlhttp.open("GET",bannercodeurl,true);
xmlhttp.send();	



</script>

It's important that the javascript is placed somewhere after the div, like in the example. You will need to replace http://www.example.com/bannercode.html with the url to the file containing the banner-code.

J. H. Rasmussen,

Works like a charm… you have re-energized me again for working to get a handle on javascript.

I owe you a cold one when next we meet at the tavern.

Thanks again… and be safe.
