make sure that new page's headers do not cache.

In addition to sending the correct no-cache headers (which don't always work with certain browsers and clients), you could also attach a random string to the URL as a GET variable, so that the browser thinks it's a NEW, unread URL. include this function (straight from the manual) via a function library: Then to get a random number, Then you can echo it as a get var or querystring on any URL: location.href = page.php?r= location.href = page.php?

You may be able to use the header() function to send headers telling the browser not to cache the page. Take a look at the header() manual page and there is an example (6th gray box). www.php.net/header ---John W. Holmes... PHP Architect - A monthly magazine for PHP Professionals.

[PHP] PHP Page Refresh on Redirection
I have a PHP page with a form that submits to another PHP processing page. On completion of the PHP actions on the processing page, I have echoed into the page the javascript action of 'location.href=...' and the location is redirected to the PHP form page that starting the process. Both pages take data from an SQL server. The problem I'm having is that the the javascript always grabs the cached page. I need a newly refreshed page to return with updated data from the SQL server.

RE: [PHP] Page Refresh
That is my goal to only use only file and I do use a lot of IF statements. I will try this. I have not used the Header() function. I will take a look at it. If you have an example, that would be great. -Original Message- From: Justin French [mailto:[EMAIL PROTECTED]] Sent: Tuesday, April 23, 2002 10:06 AM To: Crane, Christopher Subject: Re: [PHP] Page Refresh Importance: High i don't undertand why you have the meta refresh in there, but the porblem you have is simular to any one who clicks refresh on their browser... essentialy, what you want to do is after the DB insert, use a header() redirect to a blank form -- steps might look like: 1. form.php (blank) [click submit] 2. validate.php a) if not ok redirect to form.php (with entered data) b) if ok, insert into DB & redirect to form.php (blank) In other words, form.php doesn't actually print any data to the screen, it just evaluates the entered data, and acts upon it. The value of this is that if the user never sees validate.php, they can't refresh it (or have a meta refresh), so the data can't be inserted more than once via a refresh. if they refresh the form.php, the DB will not be affected. If you're cleaver with if() statements and other control structures, you can actually achieve this effect with only one file (form.php)... but that's another story :) Have fun, Justin French Creative Director http://Indent.com.au on 23/04/02 11:47 PM, Crane, Christopher ([EMAIL PROTECTED]) wrote: > I use a template page and then split out the middle of the page to do my PHP > stuff depending on a variable I pass to it. > I have a problem I hope someone can help me on. > The template page has a meta refresh in the header set for 60 secs.

Re: [PHP] Page Refresh
You could use a SESSION variable called for instance 'SUBMIT_TO_DB'. After submitting to the database, you simply set this variable 'SUBMIT_TO_DB' to 'NO'... The next time the page is reloaded, you won't have to submit one more time to the database, provided you check whether 'SUBMIT_TO_DB' is 'NO'. And opposite: if it is not set, you SHOULD do the submission to DB. My $0.02 Eivind -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Page Refresh
I use a template page and then split out the middle of the page to do my PHP stuff depending on a variable I pass to it. I have a problem I hope someone can help me on. The template page has a meta refresh in the header set for 60 secs. One of the things this page does is insert data into a MySQL database. The problem is once it is finished it displays the same form used to enter the data in the MySql database for another record to be added if you wish...here comes the problem. After the first insert, the data form is redisplayed, but after the 60 secs and the refresh takes place it runs the last insert again. If the user just leaves that page up, every 60 secs it will insert another record every 60 secs. I was thinking there may be a mechanism to redirect to a different URL after the database insert, but I do not know how to do that. I want to keep the meta refresh because there is a lot of dynamic data displayed on the template page that changes. Which is the reason for the Meta Refresh to begin with... Christopher J.
