How To Prevent A Whole Page Refresh

Oct 23, 2007

I built a site in PHP. All the site is working with the same URL, which is rachelkinarti.com. My paging is done with forms that sends the submit info to the same index.php script.

The problem is that every time a user is changing the page (via the main menu or other ways), all the page is refreshed (dissapear for a while and appears again with the new page), even though most of the page is unchanged.
Does anybody know what can cause that problem (maybe caching issues?) and how can I solve it?

Refresh To Next Page To Prevent Timeout Concerns?

Nov 27, 2010

I'm trying to manipulate my mysql tables with PHP but when I update them via PHP I have trouble with time out concerns. Is it possible to refresh or "start a new session" while continuing on from last session? So it doesn't time out? Or is it possible to somehow go to a new page to prevent time outs? Maybe switch over to a new page after 150 successful queries or after 10 seconds?

Prevent Form From Submitting On Page Refresh?

Aug 20, 2010

I am trying to learn PHP. I have set up a database, a table, and made a form that allows me to add new rows to the table when the submit button is clicked. The problem is that the form also submits any time the page is loaded or refreshed, which results in a bunch of empty rows in my database table. How do I make it so that my PHP form only submits when the user clicks the submit button or clicks the enter key? [URL]

Here is my HTML form:

<form method="post" action="things-to-do3.php" class="form">
<div class="formfield">Person: <input type="text" name="person" /></div>
<div class="formfield">Task: <input type="text" name="task" /></div>

The question is simple: How can I prevent from adding the same item again in the cart if someone refreshes the page? Cause now every time someone refreshes the page, it changes the quantity to +1 for the specific item..

Also, after moving to the checkout page, if they press the back button in the browser, AGAIN the quantity will change to +1;

Prevent Variable Update After Page Refresh Without Javascript?

Jun 1, 2011

A friend of mine is developing a web application that's more of an online learning facility. On each page is a set of questions. He wants that when the use has answered all the questions on a page and submitted (and taken to the next page for the next set of questions), he shouldn't be able to go back to answer and resubmit those questions again. The idea is that "opportunity comes but once". He doesn't want to use javascript because it can be disabled which leaves him with server-side coding. He uses PHP.

Prevent Duplicate Record Insert On Manual Page Refresh?

Sep 16, 2010

I have a problem which has only just surfaced itself. I'm working in a MVC environment. The method names in my interface class match those of the request module and action i.e. ?module=test&action=action would result in a method called public function test_action() { }

In this particular problem, I have a form which submits to itself. If validation passes, a record is created and I then show the template of another module. This module expects a series of post variables as it is used in two modules.

The problem I'm having is that, if the user successfully passes the validation and attempts to F5 the page, another new record is created etc. How can I prevent this from happening?

Normally I would header redirect after a successful insert but in this instance I can't.

Refresh Problem - Last Command Gets Re-executed - How To Prevent?

Jul 17, 2005

Working on the PHP DB I took over I have just come across a problem. When the user presses refresh in some circumstances the command they just performed will be re-performed. In some cases this is very undesirable.

Further example:

There is a PHP page in my web application that has a text box and the ability to add a note to the account the user is currently viewing. When the user presses submit the page reposts to itself with a hidden command parameter so the form knows what to do before redisplaying the account
details (with the new note). However if the user presses refresh, the command gets re-executed again and we now have another identical note added to the account.

Not desirable behaviour particularly when it comes to editing / deleting items etc.

Bearing in mind this is a large application that will have many pages to change and a Monday deadline for new changes, what is an easy way I can prevent this? How do other people cope with this? Maybe from the start the whole thing should have been approached differently but I have to work with what I have.

Best Way To Prevent Refresh Rerunning Php Code In Script

Jul 23, 2007

I have a fairly simple PHP page, which takes form input for a message, and on pressing the send button, it sends an email out.

The problem I have is that when a user presses refresh, it sends the email out again.

I use a form action to send a hardcoded value of sent=1, which reruns the script in order to send the email out.  So when pressing refresh, it still has this value of 1 set, and hence the issue.

Does anyone have any advice on how best to deal with refresh, so its not processing the form again?

Prevent Duplicate Record Insertion On Refresh Without Redirecting?

Jan 30, 2011

I have this bit of script:

if (isset($_POST['comment_posted'])) {
$user_comment = mysql_real_escape_string($_POST['user_comment']);
$add_user_comment = Event::addUserComment($id,$user->user_id,$user_comment);
}

After a user submits his comment, and refreshes the page, he is being presented with the "you are going to resend the post data" warning. And if the user accepts, it will re-insert the user comment.I understand that I can prevent that by adding using the header function and redirect the member to the same page. Is it possible to solve this issue without redirecting the member?

Refresh Page - Or An Absolute Refresh Not Reload.

Jul 17, 2005

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 http://domain.com/view_pictures.php the image
does not change.

If I use a header("LOCATION: http://domain.com/view_pictures.php"), 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
works.

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

Prevent Memcache Storing An Incomplete Page When Someone Clicks Away Prior To Page Load Completion?

Oct 14, 2010

I'm fairly new to memcache so apologies if this is an obvious one. I have looked through the memcached documentation and tried various Google searches but to no avail. The setup :

Drupal 6.19
Memcache API and integration module
Authcache module
Centos 5
Memcached 1.2.6

If you need further information let me know. The situation: Memcache is certainly running, bins are being filled and page load times are incredible. However, I noticed only recently, when doing some testing that when I clicked on a link before the page had finished loading memcache stores the current page state in memory. So, when the next user comes along he sees a half formed page that I was too impatient to wait for.

Your response might be to sort out my page loading - which I'm looking in to. But I would like to solve this one as well. This means that if a user with a particularly slow connection is the first one to visit a page then he / she might click away and store an incomplete page for everyone else to see.

Prevent Included Htm Page From Being Loaded Outside Of Parent Page?

Jun 28, 2011

I have a page thisfile.htm, which is included in thisfile.php

I used to load thisfile.htm into an iframe on thisfile.php but because of iPad scrolling trouble, I recently converted everything to scrolling divs and php includes.

I need to prevent the htm file from being loaded independently of the php parent. When I used iframes, I had no problem doing this with some javascript. But I can't get it to work with my php include - I get a loop.

This is in child:

<script type="text/javascript">
if(top.location.href==self.location.href) {
location.replace("thisfile.php");
}
</script>

This is in parent:

<div class="bigdiv"><?php include "thisfile.htm" ?></div>

Redirect A Page And Load/refresh A Div Within That Page Using Ajax?

Jun 3, 2011

I am using ajax to redirect to a page by window.location = "page.php"After the page is redirected I need to load a div within that page. For example search.php. I have been reading up on how to do this and from what I gather you can do this by using jquery. I have never used jquery .If it can be done without jquery even better!

Edit: Let me explain again what I am trying to do. I have a table that updates that the db. All of it is done through php, js and ajax.

For example "Displaytable.php" displays the table. The user can search and it replaces the search result in a div. When someone wants to update it goes to update.php. After it's updated i want to redirect the page to Displaytable.php with the search results in the div. I am using session variables to do the search. The search works fine i have tested it in another page.

Page Caching - Content Does Not Change When Refresh Page

Sep 21, 2009

I am trying to experiment with page caching. I would like my page to be cached by the browser for 15 mins. Because the page content does not change much but it downloads thousands of the same records from the database every time the page loads. I am generating the following header:

<meta http-equiv="Expires" content="Mon, 21 Sep 09 14:26:47 +0000" />
<meta http-equiv="Cache-control" content="private" />

with the following php code:

gmdate(DATE_RFC822, (mktime() + 900));

I am also printing out the the current time on the page to check if the page is really being cached or not.

echo date("H:i:s");

It is my understanding that the time would not update on the web page if the page is really being cached.
Unfortunately it's not

Cookie - Page Load Or Page Refresh

May 22, 2007

this is supposed to show file1.txt, then file2.txt and so on on page load or page refresh. But it only shows the first 2 txt files. Can someone help me find out why?
I would think that as long as the cookie is still the same if (isset($_COOKIE['e'])) {
setcookie("e", $a++, time()+60*60*24*30);} that it would go to the next text file but its not. Please let me know, thank you very much.

<?php
$max_files = 12;
$a = 0;
if($a == 0) {setcookie("e", $a, time()+60*60*24*30);} /* expire 30 days*/
if (isset($_COOKIE['e'])) {
setcookie("e", $a++, time()+60*60*24*30);}
if ($a == $max_files)

$include_file = "file" . $a . ".txt";

Changing Text On A Page Without Page Refresh?

Jun 8, 2009

I am a complete PHP noob and whilst I have done some HTML and CSS, I am not even sure if PHP is the best way of doing what I want to do. I am also not sure of the correct way of phrasing what I am trying to do, so unsurprisingly, I haven't found anything in the forums or on the web.

I want to avoid using Javascript if at all possible.

Here is my sample code:

<table width="660" border="0" align="center" cellpadding="0" cellspacing="0" >
<tr>
<td>
<table width="100%" border="0" cellspacing="0" cellpadding="0">
<tr valign="top">

[Code].....

As hinted at in the above code, when one of the unordered list items is clicked, it should update the body text below, either with a couple of paragraphs of text stored in a variable in the page, or maybe stored in a separate text file, I don't mind which.

My biggest aim is not to need a page refresh to update the text, followed closely by not using Javascript.

Populating Array With Variables / I Have Code In Place To Prevent This On The View Cart Page, Just Not The View Product Page?

$cartLimiter[$itemNo => $cartQuantity];

Using an array so the position number becomes the item number and the cart quantity becomes the assigned value, however it doesn't seem to like it and throws out on the bottom line of code:

Page Refresh Or Something Better?

May 28, 2010

All of my pages are 2 step. Step 1, user selects criteria, then clicks the button which fires a function on my proc.php page (a page of functions). Then I use header(); at the end of the function to go back to the page that sent it there. This works because at the top of each page I have an include(); that includes many other .php files that are classes. So the data is loaded into the classes, and then the page is loaded and data is displayed as the page opens.I now have one page where I want all the data to show up, no filter. What is happening is the page loads with an empty form. If I refresh the page, the data appears in the form.This ge has the same includes(), but instead of having the page go to proc.php, I just have the code that gets the data at the top of the page... after the include() at the top. So I'm guessing that the page loads, and the class is filled with data, but because the class is included before the code that gets the data is run, it can only display the data it's holding after a page refresh.

How To Prevent Page Refreshes

Jul 28, 2007

I am trying to come up with a method to prevent users from refreshing/reloading a page using PHP

I am making a PHP web based game. I don't want players to reload the page because it will reset the game -- this will be a way for them to cheat. It isn't a Flash game -- it's a pure PHP based combat system.

The best way I can think of this is to generate a random number and use that number for the combat instance. Store that number in a mySQL table and do a check to see if the number is the correct random number for the combat instance.

If the page reloads then a new random number is generated and the check fails, which doesn't allow the combat instance to display thereby preventing the player from cheating.
