Avoid Page Reload Resend - Data Message With It?

Aug 17, 2009

I wrote a simple Contact Us email form (actually a WordPress page-template file). All the code is in one file. After the user submits the form and the email is sent, the file generates a Thank You message. If the user reloads the Thank You page, they are prompted to "Resend the Form Data," which is why I am asking this question.

My question: How do I avoid the prompt to resend the form data and still keep all of my code (including the Thank You data) in one file? EDIT: I've seen folks use headers( Location: ), but I don't think that will work for if I want to keep all my code in one file.

Caching - Clear Browser Cache To Avoid Form Data Resend After Refresh

Nov 16, 2010

I'm developing a PHP-MySQL app that enables registered users to enter text comments. Problem is:

User sign-in into the web site - OKAY
User presented with a form to submit text comment - OKAY
User enters text comment and submits - OKAY

I have a routine that sanitize the comment & save it into MySQL (with userid, textcomment, datetime stamp) & present back the user that his/her comment is entered - OKAY

User decides to refresh browser - a duplicate comment is entered - BAD!

I was thinking 3 options: OPTION 1: Routine that checks: last time user posted comment, and if so, check if this is a duplicate. If duplicate then display error message. OPTION 2: Routine that does not allow a user to post too quickly. So basically do not allow postings of comments within 1 minute or so. So if browser is refreshed the comment will be ignored. OPTION 3: Manipulate the browser cache to clear out its contents so when refreshed no duplicate will be entered.

Now in the context of my application, my concerns with OPTION 1 and OPTION 2 is performance PHP-MySQL since I already have various queries within the same page that push/get data from databases. So OPTION 3 may target the issue differently. Questions is: If I go for OPTION 3 can this be considered a Best Practice?

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

Aug 23, 2010

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:
<?php
session_start();
$_SESSION['message']++;
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'].

Avoid Dead Message In Comet Chat?

I am doing Comet chat with Erlang and PHP. But now I think I met a problem: the polling connection will disconnect and reconnect automatically in about a certain time (I set this with 10 seconds), so there will be a period of time that the user doesn't connect to chat server. If a user send message at that time, the message will be dead (no one could receive it). In the client code I am using jquery with jsonp to realize the polling connection.

Page Reload

Jul 17, 2005

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?

Reload Page On Die

Feb 4, 2006

I have a query that seems to fail about one out of five times, resulting in a completely blank page. Here's the query and the call to it (which appears before any HTML is displayed): PHP Code:


$query = "SELECT msg.id, msg.to, msg.from, msg.subject, msg.date,
  u1.first_name as to_first, u1.last_name as to_last,
  u2.first_name as from_first, u2.last_name as from_last
FROM messages msg, userprofiles u1, userprofiles u2
WHERE msg.read = 'n' AND u1.id = msg.to
  AND u2.id = msg.from AND msg.to = '$userid'
ORDER BY msg.date DESC";
$reslt_message = mysql_query($query, $conn) or die(mysql_error());

If there is anything wrong with this query, please let me know. Otherwise, assuming that the query is ok, would it be wrong (or even work at all) to put a header inside the "die" that reloads the page, or would that be bad practice? I can see the possibility of getting an infinite loop, but that could be remedied by adding a variable to the end of the header that would force the code to reload only if it hasn't reloaded yet. if that is clear. When the page crashes, refreshing it works. If I click the link to this page 10 times, it could be the 1st or 10th time that results in a crash, so I'm thinking that the query is ok but it is having trouble processing it or something, which is what led me to think about reloading the page.

Page Cache/reload

Aug 1, 2003

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.

Does 'Back' Reload The Page?

May 14, 2007

I notice that when I click the 'Back' button my previous script runs, i.e, all the php code runs (I previously thought that maybe the previous form displays without the code re-running).
However, I do not get the expected value displayed on my form.

After populating one element in formA with &#3917;' (just any number) and submitting to formB (using POST ---> Redirect --> GET to avoid the 'expired from cache' message) I then click the 'Back' button and the 17 does not appear. In the code below, after clickng 'Back', I see as output from the echo statement that rb_value[0] is, infact, &#3917;' but within the form, the text element named rb_value[0] displays as empty.

Does anyone have suggestions why this might be?

It might have to do with that I do not understand what the 'back' button does. Or maybe with my PRG (post - redirect - get) model.

Here is part of the code:
echo "rb_value[0]=".$rb_value[0]; //After clicking 'Back' I see that rb_value[0] is 17

if (isset($rb_value[0])) {
$rb_val = $rb_value[0];
} else {
$rb_val = 1;
}

$line.= "<td width="20%" valign="center" align="left"> ";

// This element displays as empty instead of the expected 17
$line.= "<input type=text name="rb_value[0]" value="$rb_val" size="25" maxlength=25 </center> "
$line.= "</td> ";

Keep Values After Page Reload Of JavaScript?

May 9, 2011

I have a PHP file with a form. This PHP file uses a JavaScript for a drop down pre-selection. If a user selects a value in drop-down1 then there is a limited selection in drop-down2. This JavaScript definitely needs to reload the PHP file for changing the values of the second drop-down2 list. How can I keep the entered values of the user in the form, after the JavaScript has been executed. Currently all entered data get lost.

One option would be to set all values into the URL and grab them with GET. Yes.. that would be an option but as I am using 13 values, the URL would look not too nice. I don't want to user to take notice of what happens.

I cant use the POST, as I don't push the posting button.. it's just the JavaScript that gets executed and reloads the page. I thought about filling the Session with the entered data but that is not directly possible as JavaScript is on the client side and the session is on the server side.

Form Example:

First Name (text box) Last Name (text box) Age (drop-down) Sex (drop-down)
Province (JS drop down) District (JS drop down) Commune (JS drop down) Village (JS drop down)
Transf.from (drop down) Health Center (text box) Ambulance (drop-down) Self.transferred (drop down) SEND BUTTON..............
