PHP - A Simple Way To Just Reload A Current Page.

This topic has been moved to Ajax Help.

The Script:

<h1>Do Add a Message to the MySQL Database</h1>
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="POST">
    <textarea name="message"></textarea>
    <br/>
    <input type="submit" name="submit"/>
</form>

<?php
// The Connection to the Database
// Taken Out

?>

<?php
// To insert the text data into the MySQL database.
if(isset($_POST['submit'])){

$tqs = "INSERT INTO messages (`message`) VALUES ('{$_POST['message']}')";

$tqr = mysqli_query($dbc, $tqs) or die(mysqli_error($dbc));

}

?>

<?php
// To select the text data from the MySQL database.
$tqs = "SELECT * FROM messages";
$tqr = mysqli_query($dbc, $tqs);


// To print out the text data inside of table on the page.
echo "<h1>This Is Where the Messages Gets Printed on Screen</h1>";
echo "<table><tr><td>ID</td><td>The Message</td></tr>";

while($row = mysqli_fetch_assoc($tqr)){

    echo "<tr><td>" . $row['id'] . "</td><td>" . $row['message'] . "</td></tr>";

}

echo "</table>";

?>

1. When I have added text with the form to the MySQL database... 2. ... and I have clicked on "page reload" in Firefox to reload the page... 3. ... then the before submitted text gets submitted again to the MySQL database.   So basically, add text with the form to the MySQL database, reload the page in Firefox, and the before added text will get submitted to the MySQL database again.   My Question Is: What is the proper way to avoid this?

Hello,

I am having issues with getting cookies to function how i'd like them to.  My goal is to be able to capture a cookie value from the url if a user comes to my site via something like adwords.  An example URL they could come to is http://www.mysite.com?kw=hello

I am trying to capture the word 'hello' and tie it to that visitor regardless of where they go on the site.  I need to use that value to pass through if they complete a form on my site so that i can track the keyword source.

I have included the following as the first line of code on every page of my site:
Code: [Select]
$kw = $_GET["kw"];
setcookie('kw',$kw);
Then, if i go to this url:  http://www.mysite.com?kw=hello and then later go to a url like this:  http://www.mysite.com/page1.html, i am able to echo out the cookie on page1.html using the following code which is contained in page1.html: 
Code: [Select]
echo $_COOKIE["kw"];
The problem is, if i then refresh page1.html i can no longer echo out the cookie--it disappears.  I need the cookie to stay with the user no matter what page they are on within the site and not matter how many different pages they visit. 

I hope i am explaining myself in a way someone can understand.  Perhaps cookies aren't the best way?  Should i use sessions instead?

Thanks in advance for your help

is this possibe with php?

I am trying to create a script that alters the navigation div depending on the page the user is on.  How do I get the current page using PHP?

Hi,

This may be something for JavaScript but I would like to know if and how it's possible to show who is currently active/viewing the page. Users are logged into the system with their own account.

The purpose of this is for a CRM where more than one person may be editing the same record, so undesired overwrites might occur which is what I'd like to avoid with this "other user editing this record" notification.

Hi all,

I want to get the current page name as displayed in the URL, not neccesarily the name of the PHP script that is running.

E.g. I have a PHP file 'home.php' that contains iframes that contain other PHP files such as 'frame1.php'. What I want is a script that can be run from frame1.php but that will return 'home.php' as the current page (as displayed in the URL in the browser).

How do I do this?

Thanks!

Hi guys, I'll try to explain this. I'm doing a quoting system for a building contractor and I have a dynamic purchase order created for every quote that's confirmed and it spits out all the materials they will need for each supplier. The layout of the page is exactly what I need emailed to the supplier so they can ship out the materials listed, it's your basic purchase order. I'm going to put a button on the page that sends the email to the supplier but I need to attach the purchase order displayed on the page. Preferably in PDF but it just needs to be an attached file. I know I can have the user use PRINT.... to save it as PDF and then use Outlook to email it but I'd like to automate it. Thanks.

Hello, I got this basic code from a website and it is supposed to highlight the current page on the menu, which it does very well. The problem is that I cannot stylize the font, color or size of the type in the current page menu display. No matter what I do, it always stays as the default font. The other buttons on the menu can be stylized but not the current page. Is there a way to do this?

Code: [Select]
## SNIPPET 1 - THE PHP ## // To be saved in the 'includes' directory as "nav_include.php"

<?php
$menu=file_get_contents("includes/menu.html"); // get the navigation list of pages
$base=basename($_SERVER['PHP_SELF']); // get the current page
$menu=preg_replace("|<li><a href=\"".$base."\">(.*)</a></li>|U", "<li id=\"current\">$1</li>", $menu); // add an id of 'active' to the link and id of class to the list item for the current page 
echo $menu; // echo the HTML list with the current page highlighted
?>

## SNIPPET 2 - THE HTML LIST ##  To be saved as menu.html

<ul id="navlist">
  <li><a href="index.php">Home</a></li>
  <li><a href="products.php">Products</a></li>
  <li><a href="services.php">Services</a></li>
  <li><a href="about.php">About Us</a></li>
  <li><a href="contact.php">Contact Us</a></li>
</ul>

## CSS ## for the *.css file

#navlist { margin: 0; padding: 30px 0 20px 10px; float: right; width: 60%; }
#navlist ul, #navlist li { margin: 0; padding: 0; display: inline; list-style-type: none; }
#navlist a:link, #navlist a:visited { float: left; line-height: 14px; font-weight: bold; margin: 0 10px 4px; text-decoration: none; color: #4F4F4F; width: auto; } /* link and visited link styles - the visited state can be styled separately if you wish */
#navlist a:link#current, #navlist a:visited#current, #navlist a:hover { border-bottom: 4px solid #66733f; padding-bottom: 2px; background: transparent; color: #4F4F4F; } /* this line's the style for the current page link */
#navlist a:hover { border-bottom: 4px solid #4F4F4F; color: #4F4F4F; } /* hover state for all the links */

## TO DISPLAY ON THE PAGE ##

<?php include("includes/nav_include.php"); ?>

I've looked at loads of other scripts that highlight the page but none of them work on mine . Here's part of my code:


$i =1; 
for ($x=0;$x<$foundnum;$x=$x+$e)
{

 echo " <a href='search.php?search=$search&s=$x'>$i</a> ";


$i++;

Is there a function to check the name of the current page? Such as login.php or something like that? If not, does anyone have a custom function already created?

I'm feeling a little overwhelmed/burned-out/confused...   

I have a page "article_index.php" that contains a summary of each article plus a link to it, e.g.

Code: [Select]
<a href="<?php echo WEB_ROOT; ?>articles/postage-meters-save-you-money">
When you click on a link, it goes to "article.php" and uses a mod_rewrite to transform the "pretty URL" to regular URL that "article.php" can use to query the correct article from my database.

-----

Here is what I need help with...

When a user is on a given article page, I want to sto

- ReturnToPath
- ArticleID

in the SESSION.

I am drawing a blank on how to get the "ArticleID" when a user is on a give page?!   

Hope you guys follow me?!

I have a few PHP files. Currently, if the URL contains page=var, index includes var.php, otherwise it includes home.php.

Apparently, this method makes the site easy to hack through Remote File Inclusion. Also, using PHP5 breaks this method entirely, as no matter what you set page to in the URL, it includes home.php.

What's the best way to do this without using the URL? Give example code if possible. I've used PHP for a while but haven't really gotten past the beginner level. I'd really appreciate any help.

Thanks.

I'm doing a cURL post to a server and it returns "true No_Error Data was accepted 10356546 3770 false 0 "


Form --> Method=Post --> submit.php (this is the page that's doing the cURL post and the server returns data that appears on this page).


How do I take this and put it into a string?
