why not working?!

Geoff Cox · Mar 7, 2007

Hello,

The code below is aimed at passing the date in the yyyyMMdd format
from the javascript calendar in an html file to the php in a another
file which then searches a MySQL database.

For some reason the sendPhp is not working.

I need to send

target=frameright (as the results of the next.php search appear in the
right hand frame), and

submit=1

Any ideas please?!

Cheers

Geoff

What happens when you try to call sendPhp? Do you get a particular
error message.

I have encountered problems in the past when using a relative url with
XMLHttpRequest.open(), so I routinely use fully qualified urls now as
it seems to avoid a lot of problems.

hth.

No error message appears!

by full qualified you mean sendPhp("<a href=\"next.php etc?

Sorry, I meant that your should try including the full path within the
url. I.e. use "www.google.co.uk/somedir/somepage.htm" rather than just
"somepage.htm".

OK will try that.

I am trying this on my own PC so is this correct?

sendPhp("http://127.0.0.1/sounds-great/members/sounds-great-right.php?term=newdate");

Above doesn't work though!

req.open("GET", url, true);
sreq.send(null);

so "req" or "sreq" ? ;-)

I know - another typo! Should be req.

Please name the topic with an appropiate title. "Why not working" is
really a bad idea.
Thanks.

Ah, in that case, I'd suggest running a packet analyser such as
Ethereal to examine the network traffic between the client and the
server when xmlhttprequest.open() is executed. See if there is
anything anomalous. I'm assuming here that the web browser is on a
different pc to the server.

Failing that, insert some alert() statements into the sendPHP function
to try and gauge where it is falling over.

You could also try changing the xmlhttprequest to use a synchronous
request and see what is returned:

function sendPhp(url){
var req = xmlreq();

req.onreadystatechange = stateHandler;
req.open("GET", url, false);
req.send(null);

alert(req.status); // show the http status code of the
xmlhttprequest, should be 200
};

};

It is indeed 200. In fact I am browsing from the same PC at the local
(127.0.0.1) server as I'm still testing this. Is this OK?

The code used to get the 200 is as follows - you can see that I am
trying to get the date, newdate, from the JavaScipt to the php in
another file with the hope that in this file a search will be made of
the MySQL database and the results appear in the right hand frame.
There are 3 frames - a top one and below that a left and right hand
frame. The file with the code below is in the left hand frame.

I not at all sure whether the url is right?

In the php file I am using the $_POST[] array etc.

Any of this seem wrong?!

Cheers

Geoff

Finally got it working!!

I have used following approach instead of the AJAX approach.

window.parent.frameright.location.href = _
"http://127.0.0.1/sounds/members/sounds-right.php?searchfield=" + _
value + "&term=" + newdate + "&submit=" + submitvalue;
