Refresh The Page When A Form Is Submitted & Give An Error Message?

What I have right now is a form with simple input fields such as name, phone number, email, and comment.


It goes to a new page and shows the error (if there is one) and if not it goes to a blank page (I know how to make it go to a page but it needs to be kept on its current page) It does work with sending the info to the email.

I have tried header("Location: ".$_SERVER["PHP_SELF"]); And it didnt work..

$_SESSION['message'] : When I Hit Refresh And Reload The Page The Number Doesn't Increment?

It's working to my favor but I don't trust it unless I know why it's working.Real world example:

I reference $_SESSION['message'] twice in my code.First looks like this:[code]...

Second looks like this:echo $_SESSION['message'];

For some reason, this is working for me and $_SESSION['message'] is getting unset after it's echo'd (but the user remains logged in so I know the entire session is not getting unset).

Test example: I put the following code in test.php:
echo $_SESSION['message'];

When I hit refresh, reload the page, etc. the number doesn't increment, it's stays as '1'. If I change it to $_SESSION['success_message'] the number does increment.So? Is $_SESSION['message'] reserved? Does it automatically reset once it's echo'd? I didn't find anything in the manual on this.

UPDATE:I just checked in Firefox and test.php works as expected. In Chrome it doesn't. Chrome does so many wacky things, I wouldn't be surprised if it's resetting $_SESSION['message'].

GetFeed - Send Request Every Couple Of Seconds Without A Page Refresh?

I'm retrieving an XML feed via php:

PHP Code:

Now this is working fine and I'm able to work with the XML data to populate my website - this data is only updated when the page is refreshed; therefore I wondered if there was a way I could send out this request every couple of seconds without a page refresh?

HTTP Post Request Via Javascript : How To Refresh A Page And Send Post Data At The Same Time?

I've encountered a small problem building a web application.

My thinking was simple: application [web music player] reads $_POST['itemId'] every time it is loaded. If it does not exist, the player doesn't start playing a song, but idles, otherwise it plays a song with itemId.

Now the problem comes here: when a song in a playlist is finished, I'd like to refresh the page and send incremented itemId via post request, so the server side will know which song I'm currently listening to.
I've searched the internet for possible solutions how to refresh a page and send post data at the same time, but all I've found are Ajax tutorials.

Script That Send Data To A Website So That It Will Send A Text Message To Phone Alerting?

Is it possible to write a PHP script that will send data to a website like Twitter so that it will send a text message to my phone alerting if certain things happen?Say I am monitoring a temperature with an existing PHP script running every 5 minutes on my server. What if I want to expand this such that if the temperature falls below a certain point, or rises above a certain point, it will alert me via my cell phone. Sure, I can do e-mail alerts, but I will not be able to see the e-mail without a WiFi connection (have an ipod touch, but not an iphone or anything). I've used PHP to read data from other websites, but I've never sent data to other websites and I don't even know if it's possible. If it is not possible PHP, which language is it possible with?

Refresh Page - Or An Absolute Refresh Not Reload.

If the image content for image1.jpg changes, but the file name image1.jpg
does not, IE6 does not show the new content unless F5 is pressed.

If I reload the page using the image
does not change.

If I use a header("LOCATION:"), the
image does not change.

I have tried several ideas to force the reloading of the image file with no
little success.

I cannot change the image file name.

Even if I add another a second image, the first image does not change.

IE must use the file name to determine if it should reload the file. But F5

Is there a means in either php or JavaScript to call (force) a F5-keyboard
command? or an absolute refresh not reload.

I don't want a full blown guestbook but mealy a small section that allows people to comment on the pages content and add their opinion.

Message Forwarding System Required

Does anyone have know of an application/routine that can operate within a website to monitor incoming emails and trigger an out going email. The system would need to hold client name, email addresses and pre-defined message, which would be cross matched to an incoming email address hence incoming mail to account@domain containing a Subject Keyword equal to XXXXX, which triggers an out going email to a specified client.

Private Message System Implementation

I'm looking for a way to implement sending private messages (more like personal messages) through my website. I really just want a way for a user to view all messages sent to him/her and also view new messages.

I'm posting in the database forum because I'm planning on doing this with mysql, but I'm really asking if this is the best way to do it or if I should find some non-database way to do things. Code:

Send Email From Webpage Without Postback/refresh?

I have a webpage (php, javascript) which has a small contact form for a user to fill in and email us. Not a problem in itself, i have a working form already.

Nothing noteworthy, just a form posting to a php page which sends an email.

<form id="myform" name="myform" method="post" action="Mailer.php">

So user fills in form, hits submit and the page changes to mailer.php and they find their way back to where they were.

What I want instead is for the to stay on the same page when submit is pushed. The form div to update itself to just say 'message sent' or something. I just want to avoid a full page refresh.

Much like how on say facebook, commenting on a status only updates that div.

Designing Message Based Processing System?

Designing a RabbitMQ based message processing system for use with various PHP based web applications.PHP daemons will be used to retrieve items from a queue and perform processing.The idea is for example, emailing hundreds of receipients, the message queue will do it asyncronously to the web application.My question is, with this type of system.Detect the progress of emails sent i.e(2/100)Know when the entire process is complete.When 2 is known, send a message back to the web application when the entire process is complete?For 1, I think the daemon would send a message to a completion queue, but where would the code for items 2 and 3 be placed?

Is there anyway to do something like that?
