Hello,
I am confusing about your question. You want to see a message/status
when a function is working (file read/write). And change the status
when it done. But php is a server side language. Its print/echos are
sent to client whenever it finishes its execution all over the file.
So if you print a message before the function(write file) and after
the function, both message will show together when the clientside
browsers loaded.
So, to do this task, i thing the best way is XMLHttpRequest (Ajax
Technology). Here is an example for you...
------ the file from witch the file update fuction will call -------
<script type="text/javascript" language="javascript">
var http_request = false;
function getStatus()
{
document.getElementById("status").innerHTML
= "Updating the file......";
makeRequest('ReadWriteFile.php'); // parameter would
be the file name(path) which process you file
document.getElementById("status").innerHTML
= "Updated.";
}
function makeRequest(url) {
//alert(url); return;
http_request = false;
if (window.XMLHttpRequest) { // Mozilla, Safari,...
http_request = new XMLHttpRequest();
if (http_request.overrideMimeType) {
http_request.overrideMimeType('text/xml');
// See note below about this line
}
} else if (window.ActiveXObject) { // IE
try {
http_request = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {
try {
http_request = new ActiveXObject
("Microsoft.XMLHTTP");
} catch (e) {}
}
}
if (!http_request) {
alert('Giving up :( Cannot create an XMLHTTP instance');
return false;
}
http_request.onreadystatechange = getResponse;
http_request.open('GET', url, true);
http_request.send(null);
}
function getResponse()
{
//catch the responseText data
if (http_request.readyState == 4) {
if (http_request.status == 200)
{
alert(http_request.responseText);
} else {
alert('There was a problem with the request.');
return;
}
}
}
</script>
<input name="btnDo" type="submit" id="btnDo" value="Update File"
onclick="getStatus()" />
<div id="status" ></div>
---------- ReadWriteFile.php :: this file will update your file -----
-------
<?php
/* All of your code to read or write a file if read and want to
return data then just print them*/
echo "All of your code to read or write a file will be in this file.
Print data if you want too!!";
?>
Ok, If i can understand your problem, I think it may solve your
problem.
Thanks
