PHP :: How Do I Force A FRESH RELOAD Of A Page

Can Header() Do A Div Reload Without A Page Reload (ie Ajax-type)?
I have a display page (displaypage.php) divided into two panes - one for content and one for feedback, referred to in the CSS as contentDiv and feedbackDiv respectively.

When I click on a word in the content pane, I do a PHP/PostgreSQL search for similar words, and the results appear in the feedback pane without a page reload. For this, I am using a very basic Ajax setup Code:

Submit Vs. A Fresh Page Load
I'm developing a page - mostly for the learning experience - that
includes a form with several text fields and a submit button. When
it's submitted, there is some server-side processing and the output is
displayed as part of the same page. (the form's action attribute is
set to: "<?php $PHP_SELF ?>").

One of the steps in the PHP script is to check for the existance of a
hidden element in the form so that I know whether the page is being
sent out as a result of a new request or from the form having been
submitted.

This all works as expected. When the page is sent out as a result of
having been requested from its "home" page, the results are not shown;
when the submit button is clicked, the page is sent out with the
results shown.

Finally my question: when viewing the page with the results shown, if
I press <F5> or click on "Refresh", it behaves as if I had clicked the
Submit button (that is, it shows the results). I would expect it to
return the page as if it was a new request (and NOT show the results).

Loading Page Fresh (without Cashe)
I have a Database driven site, and I use some tricky url parsing stuff out of a file called index.php3. Now depending on where the user comes from, the url will remain the same, but the header info will be different.

Session Var Is Setting ONLY AFTER I Reload Page, Form Var Displays First Page Load
Page1 has a form that calls Page2. The beginning of Page2:
<? php session_start();
$s=$_POST['sSelected'];
session_register("s"); ?>

in the middle of Page2 I have a form varaible:
<?php echo $_POST['stateSelected']; ?>
<?php echo $_SESSION['s']; ?>

The form var displays the first time the page loads. The session var
displays only after reloading the page2.

Page Reload
I have succesfully created a login page for my site. I have used the PHP_SELF
so that once the user has succesfully logged on the page reloads. Everything
works fine the first time somebody tries to log in but when they revisit, the
log on page is bypassed and it goes straight to the information page. I have a
sneaky suspicion that this is due to the fact that the page is then in their
history of recently visited sites. How can I use PHP to refresh the page
automatically everytime it is requested?

Force A Page To Be Re-validated?
I'm trying to force a page to be re-validated every time someone views it, even when they click the back button. I'm currently using:

header("Expires: " . gmdate("D, d M Y H:i:s", strtotime("-1 year")) . " GMT");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Pragma: no-cache");

However, my pages still seem to display without the server being called when the back button is pressed.

Can anyone suggest the correct headers/code I can use to force the server to be re-called when the back button is pressed?

Combo Box Value On Page Reload
I am new to php and mySQL so this is probably something very basic that I'm
missing. Basically, on the page I have 2 combo boxes but 1 of them is not
getting the value passed when the page is reloaded so the database can be
updated. I am echoing the field names passed and the field "theDriver" is
there but it's empty. I've include the code parts where I believe the
problem should be but I'm stumped and I've been trying to solve this for 2
days without success. Would someone mind examing the following code and
tell me what I've done wrong?

Following code constructs the combo box on the page from a MySQL table:
<?PHP
$table = "tblEmployees";
$Link = mysql_connect ($host, $user, $password);

$Query = "select concat(empID,' ',empFirstName,'
',empLastName)
as full_name from $table WHERE empTitle =
'Driver'";
$results = mysql_db_query($database, $Query, $Link);
?>

    <b>Driver:</b>
<select name = "theDriver" size="1">
<Option Value=" ">Select One:</option>

<?PHP
for($u=0;$u<mysql_num_rows($results); $u++)
{
$driver=mysql_result($results,$u,'full_name');
?>
<option value="<?PHP echo($ID); ?>"><?
echo($driver); ?></option>
<?PHP
}
?> //end php

</select>

When Page is reloaded the following code is run but the combo box titled
"theDriver" is empty

foreach($_POST as $field => $value)
{
echo $field; //field names from form
echo "; ";
if ($field == "theDriver")
{
echo " - here's the driver for ya: ";
$$field = strip_tags(trim($value));
echo $$field;
$pos = strpos($driver, ";");
echo "<br> the ; is in pos $pos <br>";.......

Page Cache/reload
I have created a facility for users of a site to enter details of property (e.g. location, size etc.). This allows them to upload a picture. Users can also update a picture, adding a new picture to replace an existing one.

My problem is that if a user changes/updates the picture and then views the details the old details are displayed unless the user manually clicks refresh.

I know that this is because IE is storing the page in cache. I have tried the Meta Tags with "no cache" and "expires" but they don't work. I have also tried to get the page to refresh itself on loading, but it either doesn't work at all or keeps refreshing over and over again. Ideally i would like the page to just refresh once and then stop refreshing but there doesn't appear to be any way of doing this.

Page Reload With An <iframe>
Let me to explain the structure....

filename : api.php

Having an <iframe src="remotehost/index.php"> </iframe>

i have to reload current page api.php after some execution of remotehost/index.php ... I've tried header(); but got formal header error. can we reload current browser url from an iframed code?

Reload The Same Page With A Form After Submit?
I have a page with a form, and the code to process the form answers, I want the same page/form to just reload when the user presses submit. The only function I have found is that location command. PHP Code:

Session ID Changed Everytime Go To New Page Or Reload.
I'm new member of this group.

I had added new virtual host at my intranet server. The new virtual
host configuration on httpd.conf is similar with the old one.
At the new virtual host, the session id seems changed every
interaction to server (new page or reload).
The old one is fine, the session id keeps at the same string.
Both are at the same server.
I use Apache 2.2.3 (Win32) with PHP 5.2.0.

Tested using code below:
session_start();
echo session_id();

PHP Configuration :
session.save_handler = files
;session.save_path = "/tmp"
session.use_cookies = 1
;session.use_only_cookies = 1
session.name = PHPSESSID
session.auto_start = 0
session.cookie_lifetime = 0
session.cookie_path = /
session.cookie_domain =
session.serialize_handler = php
session.gc_probability = 1
session.gc_divisor = 1000
session.gc_maxlifetime = 1440
session.bug_compat_42 = 0
session.bug_compat_warn = 1
session.referer_check =
session.entropy_length = 0
session.entropy_file =
;session.entropy_length = 16
;session.entropy_file = /dev/urandom
session.cache_limiter = nocache
session.cache_expire = 180
session.use_trans_sid = 0
session.hash_function = 0
session.hash_bits_per_character = 5

Stop File Reload When Page Is Refreshed
I have a section of PHP code at the beginning of the page that loads a file which the user has specified in the form, on the same page. The problem is that everytime the page is refresh with the refresh button, the file loads. I want the file loading to happen only if the user has pressed the submit buttom.

Reload A Page After Execution Of A Mysql-query In Php
I am aware that this question might involve Javascript and MySQL. So
far I haven´t found a suitable solution in JavaScript ng´s - maybe
becauese php-programmers are more likely to come across the following
problem:

A script on my page relays a quite complicated query to a MySQL-server
with mysql_query(...); The query works fine but takes very long - I
usually have to wait for approx. 30 seconds before the query is
returned from MySQL and the results displayed by php on a webpage.

I´d rather have the results of the query written into a nice textfile
and display a text like "Results are being retrieved" in stead of the
actual results and have the page reloaded a f t e r the textfile has
been updated. The newly loaded page then would obviously first check
whether this very textfile has been updated or not and read out its
contents in case it is has been updated less then let´s say two
minutes ago.

I hope I can make myself understood...:)

My question is: what actual code (I am almost sure it must be
JavaScript and not PHP) does PHP have to generate in order for the page
to reload after the results are retrieved and stored in the textfile?

Reload Outside Page OnClick Of Submit Button
I'm using frames to create a "bookmark-like" page. You can enter a URL and it gets added to my database. I have two frames (leftFrame - to display bookmarks entered and mainFrame to show web page). I want the leftFrame to automatically refresh when the user enters a bookmark. As of now you must physically refresh the page to see the results. Here's my code:

Preventing Multiple Data Insertion On Page Reload
I am developing a PHP-mysql database. It is noted that when the
browser window is refreshed the data is inserted again in the
database. unfortunately there is no unique keys that I can use to
verify the existance of the data, so as to prevent the multiple
insertion. Is there any other way to prevent it otherthan introducing
another field for this purpose and verifying its existance?

Saving Selection In Drop-down Lists In PHP After Page Reload?
I can't find an answer to my quesiton anywhere.

Given a drop-down list with USA states and other text fields I pass
this information for further processing via PHP. If any of the required

fields is empty, the PHP script would return an error and reload the
form page asking to fill out those fields. All entered information is
saved... except for the drop-down list selection. I tried to write a
Javascript function which is echoed by PHP, but interpolation of PHP
variables in the Javascript section gives a syntax error message in
Javascript.

The PHP script returns, e.g., an "AL" string for Alabama. Of course, I
don't want to write PHP code for each option to make it selected.

$_SESSION Problem - Page Reload Creates New Session ID
I am having trouble using the session vars in
PHP 4.3.9
OS: Win XP Prof
Web Server IIS (is local and there are no links to other servers from
the web pages I work on)
Browser: IE 6.0

The problem I am having is that each time I reload the same PHP page, I get
a different
Session ID (and thus all session vars are lost from one page to another).

let's say in firstpage.php I set
$_SESSION["firstvar"] = "someval";
$_SESSION["secvar"] = "otherval";

and in secpage.php I try to retrieve $_SESSION["firstvar"] , it gives me
"Undefined Index error"
I did not know what is happening and when printing out the session id (echo
SID;) I found out
that the ID is changing every time page is reloaded or when moving to
another page.

The problem is that I don't know what might reset the session since I use
"session_auto_start"
and have not played with session_start, session_destroy or anything else.

Populating Fresh Data
Im building a live web chat using php, mysql, javascript, ajax I am fine with sending and retreiving data in real time using ajax as the transfer protocol However, my problem, which is becoming a nightmare, is how to I display it !! Lets say the below is the chat screen,

<div id="messages">
Jamie - Hello
Peter = Hi
Jamie = Nice Day
Peter = I know
</div>

Lets say Jamie's next message is "What are you doing today". I can send that off to the database no problem and I can get peters live chat to pull that message in, however, how do I get it to display underneath Peter = I know

As a practice I was using

document.getelementbyid('messages').innerHTML = document.getelementbyid('messages').innerHTML + "<BR>What are you doing today"

That works, but, lets just say the chat gets to 1000 lines, for each new message those 1000 lines have to be pulled out via javascript, a new line written to it and then printed back in the div

Im not sure but I'd take a good guess at this not being optimal and will cause CPU load on the users machine

What is the best way to do this! Chat messages are deleted after 1 minute, but that doesnt matter because by then they have already been sent the the users chat. Just incase you are thinking of completely repopulating there chat with every message they have sent since the chat started..

What Is The Best Way To Use PHP To "reload" Web Page?
I am trying to code my "notfound.html" page when people click on the
link that will send them back to home page, that the "entire" browser is
"refreshed".

Reason for doing this. I have frames on the home page. When user click
on the link on "notfound.html", the home page appears within the home
page frame. So I see 2 home pages. I have to physically click on the
"reload" button on the browser to the the appearance that I want. But I
know that "common" user will not think of that, and will determin that
the home page is buggy...

How Do You Force A Download?
Hello, how do I force a file to be downloaded instead of displaying it? I have PHP and HTML files that I don't want to be displayed but downloaded. How would I do this?

Force Https
I want to make sure people are on the secure version of a page (https). If a person is on the regular http, how can I force them to go to https?

Trying To Force A Login
I have an include file that I use to secure pages with a login. When I check the password, Im also trying to check the login date While testing, Im setting the time difference to less than 10 seconds. So the idea is that when i login, then come back to a protected page more than 10 seconds later, I should be forced to login again. However, im not getting forced to login after a 10 second wait. Code:

$sQuery = "Select iUser From Table Where sGUID = '$sGUID' and TIMEDIFF($login_date,LogInDate) < ༼:00:10'";
. . .
//so if no returned records...
header('Location: Login.php');

Force PHP CLI To Stay In RAM?
I have a couple of command-line PHP scripts that are often called, and
I was wondering if it were possible to have the PHP interpreter remain
in RAM instead of being removed after the scipts end?

Force A Download
i know that when i place a .zip, or .exe in my web directory, the browser automatically asled the user to download the file. however i want to place a PDF into my site, and only make it available as a download, becauase i know that especially with IE and Firefox, it reads it within the browser instead.

how can i have the file a download, instead of read?

Force Post?
I'm wondering if there's a way to force a post from one page to another, without the user having to send it in a form.

If not, how do you make a textbox in a form automatically conain a variable in it (the post from the last page)?

Reload.
I have the following problem. Using php I have composed a file which
add to an html file text typed into text-field. Problem is that I can
see new conntent of html file only after pressing "reload" button of
browser. My question is whether I can add some fragment to the html
file to force it to reload atomatically?

I need to zip an arbitrary amount of files, say maybe a $files array full of path names to the files filled dynamically from database based on an id number...

then i need it to automatically force a download of the zip file to the browser, then automatically delete the zip file when its finished...

Refresh Or Reload
Hi!

I need to make a webpage refresh using code, I don't want that the user uses the refresh button (you know! always forget to do it)

So, how can I do to do that in PHP?

Php Form Reload
I want to make a search form which contains make, model and year of make as search condition. All these information should be taken from the database. After selecting the make the model selection menu should take the value which is coming under the same make. Is it possible to reload the same page and take the value from the database. or it is possible to add a select table values where the select query contains a criteria which is taken from the same just before that.

Reload Isn't Reloading
Still getting the same issue i submitted a couple of days ago. I can use
PuTTY to edit files in-place, on production server, and when I refresh
the page the changes won't have any effect.

I have made sure the templates_c (smarty) is 777; httpd runs as "nobody"
so i made chgrp'd the whole htdocs directory to "nobody". i even
reinstalled Apache/MySQL/PHP. where should I start looking?

How Do I Reload The Php.ini File?
I can't figure out how to make PHP reload it's php.ini -file. I changed the default dirctory for storing sessions but can't make PHP re-read the file and apply my changes.
I'm using PHP 4.0.4pl1, Apache 1.3.14 and MySQL 3.23.34 on Windows 2000.

Reload Problem
I have a page that displays information from a database. I have a link that pops up a window with a form in it. The form adds content to the database. Here is my dilemma, I want the main page (not the pop up) to reload after the form has been submitted in the pop up window, so that the new content added to the database will now show up on the main page.

Reload Php-image
I've, inside an html page, an image which is created through a php file
:

<img src="<?php echo 'captcha.php' ?>">

file captcha.php, sends
header("Content-type: image/png");

All works fine, but I need to reload the image (a new captcha code
should be generated) without reloading the enitre page. Are there any
solution? I'll post a similar question in javascript forums

I'm working on a "post comment" form using ajax.

Will This SQL Dump Reload
I created and loaded a database.
The first three fields are id, first_name and last_name
I used addslashes on the first and last names.
Here is a portion of the SQL dump that I took for backup. I have
concerns about record 47 because of the single quote in the name.

Will this dump reload ?

47, 'Sean', 'O''Kelly', NULL, NULL,

It appears that SQL is using a double quote rather than escaping
the single quote.

As usual, after reassuring me, a pointer to a reference would be
adequate.

Reload Vs. Refresh
Is there a difference between reload and refresh? How is this coded in the header?

Redirection - Reload
I wonder if it posible to reload a web page using php ? ? ?

No javascript or something similar.

Force PHP Redirect Instead Of Displaying CGI Error
I am sure I found the answer before on here but I cant for the life of me find it now. I need to change the way one site in iis works when someone tries and goes to a non-existant php page, instead of displaying:

CGI Error
The specified CGI application misbehaved by not returning a complete set of HTTP headers. The headers it did return are:

How To Force A Download Of An Html File
I'm making a poll management system, and when the administrator creates a new poll I want an html file (containing the actual voting form) to be automatically forced to download via the save as dialog. How is this done? Secondly, I would prefer it not to have to be written to the server first. I just want to dump all of the text in a string variable to the save dialog.

Force Browser Download Of Content
Ok, this isn't a "How do i force the browser to download my file..." question.

This is a bit different because what i want to give the user isn't a file.

I want to provide a copy of a database table as a CSV file.

(force) Delete A Session File, How?
I dunno if this is meant for here or apache anyway.. my script uses sessions... if the person logsout.. the session is closed and the session file is deleted.. if the person just shuts down the browser the session file is not deleted and hence i've got hundreds of redundant session files.

Force 2 Decimal Places For Currency
How can I force a value to retain 2 decimal places (or atleast display them)? E.G. force $19.90 to be displayed as such, not $19.9

How Best To Avoid Brute-force Looping?
I have a style/php question. (I am a C hacker by background, and
thus everything is a loop... But PHP is different...)

I write out my array and read it back in. It comes in thus:

Array (
[currentField] => 103
[brgf1] => 0.000000
[brgt1] => 1.000000
[axa1] => 1
[brgf2] => 2.000000
[brgt2] => 2.000000
[axa2] => 2
[axb2] => 2
[axc2] => 2
[axd2] => 2
[brgf3] => 2.000000
[brgt3] => 3.000000
[axa3] => 2
[axb3] => 2
[axc3] => 2
[axd3] => 2

.....
.....
)

Basically each line consists of two bearings and 4 true/false switches.
The line number in the schedule is apended to the name of the field.

In my C mind, this calls for a loop, bruteforcing our way and appending
the counter to each name....

But I *know* there is a more elegant PHP way to do this. While it makes
sense in C, it just looks fugly in PHP....

As I use PHP to generate the field names, I can change those if it makes
things easier....

Force Download On Win2k Server
My win2k server has read write and execute permissions throughout the entire account and I can't really change it without removing those permissions throught the entire account, so what I need to do is force download an exe file, since just linking to it tries to execute it on the server. Is there some way in PHP or ASP that I can force it to download and not execute?

How Do I Force A FRESH RELOAD Of A Page

I've built a few php scripts, but since its reloading the same page I can't get it to refresh the page. I've implemented some expire meta tag...but is there anyway I can try and force it to refresh?
