PHP - Post On A Page Load

I have a page that processes a variable passed in the url to go get information out of a text file in JSON format.  For some reason though, passing one variable loads a page, passing a certain variable (who's data in the file is virtually identical to the first)  will cause the browser to just load the page indefinitely.  Maybe even more strange is that on my local machine, the variable that won't load is switched, and the other loads fine.  How can I debug what's happening when the page never loads so that I never get an error?

Hi!

I am looking for a script that counts how many queries is executed on page load?
I hadn't realised one of my scripts was doing hundreds of queries simultaneously
and never would of thought this would be the cause of high load.

As I'm developing stuff in PHP, I want to ensure minimum queries are executed
especially because I am doing this in a procedural manner and not OOP.

Thanks in advance.

Hi,

I've been wondering if it is possible to load a php page according to certain time.
For example at 12:00 pm a php form will pop up automatically informing an employee to fill in something in the form, another form will pop up at 4:00 pm, etc...


Thanks in advance

I'm trying to block access to a particular page if the visitor is not from a specific country (using Maxmind Geoip Country database), but not quite sure how to code this properly:

I tried this and many variations of this inside the head tags, bud doesn't work. Any suggestions on the best way to go about this?

Code: [Select]
<?php

require_once("geoip.inc");
$gi = geoip_open("/home/username/GeoIP.dat",GEOIP_STANDARD);
$country_code = geoip_country_code_by_addr($gi, $_SERVER['REMOTE_ADDR']);
geoip_close($gi);

if($country_code !== 'US')
header("HTTP/1.0 404 Not Found"); 
exit; 

?>

can someone please help me with this
I'm trying to make it so that when the page loads
just the condition below will happend unless the if statment happends.

so I need two if statments that work off of one condition? so i was thinking of using OR
but i would need a if statement that says the page is being loaded

what this code does it displays someones profile when search is hit
but i want it to display the persons own profile soon as the page is loaded first






Code: [Select]
<?php
if(isset($_POST['search'])) {

// searches goaulds then displays them
$search3 = "SELECT goauld,id FROM users WHERE goauld='".mysql_real_escape_string($_POST['goaulds'])."'"; 
$search2 = mysql_query($search3) or die(mysql_error());
WHILE($search1 = mysql_fetch_array($search2)){ 

$grab_goauld = $search1['goauld'];

echo '<table width="300" height="5" border="1" align="center">';
  echo '<th><center>Goauld Statistics</center></th>';
  
   echo "<tr><td height='340'>$grab_goauld</td></tr>";
   
    }
}
  echo '</table>';
  
?>

Hi,   I am trying to make a page where the footer is loaded according to the screen size, so if someone is accessing the website via a tablet will be a footer, if it is from the computer, there will be another footer.   my problem is that although it is recognizing the windows width, it is not changing the footer accordingly.   this is my code:

$width = "<script>document.write(window.innerWidth);</script>";
if ($width < 900)
{
include("footer_mobile.php");
}
else
{
include("footer.php");
}

for some reason it is always loading the else footer even though the windows with changes. I added echo"$width" ; and the result of the variable was fine.     does anyone know what the problem is cause it is driving me crazy?

Hi,

I have a div which reloads every 10 seconds but I want it so that if it equals something then redirect the whole page when at the moment it just loads the whole page in in the div but need the div as it stores all my variables, anyone know of anything else I can use?

Thanks

Is there some way of a php include which is visible on every page (footer), itself having two php includes, but only one of which would be visible, then on the user refreshing the page or on visiting another page on the site, that include would be replaced with another php include?  Preferably done without any js.

Any help appreciated.

So I have a page that has profile images basically, but these images cache and when someone clicks on anything, like rotate image, since my script rotates the image and saves it correctly, I can hit Ctrl+F5 and the image then shows up correct, but the page loading itself after running my script using a get method and then using the header coming back to the same page the image looks like it wasn't reloaded. Noones gonna hit Ctrl+F5, so how do I get this to cache the image completely when the page reloads? I've tried
<meta http-equiv="pragma" content="no-cache" />

But this doesn't work, well nothing seems to work really.

I am creating a stream page that updates automatically without the page reloading by reloading a div on the page using a timer. However, I only want it to run the update and fade in/fade out when there is a new status in the table. I tried doing it through PHP getting the number of rows in the table on the page itself and then checking the number of rows on an action page, however, the number of rows didnt update when the div was reloaded. I then tried doing it using jquery/javscript but had the same problem.

How can I acheive this?   Thanks in advance

hi! i dont know if the query below from mysql is slowing down the page or i have not written it properly:

Hello All,   I have been going crazy trying to figure this out, I hope someone can help me out   I have header and footer.php files that on all my pages I get them to load with include,   but for some strange reason, this certain page it will not load I did some research and apparently theres problems with div and php, does anyone know how to make this work?   Thank you in advance, Elaine Attached Files  test.txt   4.81KB   7 downloads

lets say I have two pages:

Code: [Select]
one.php

Code: [Select]
two.php
Now with that in mind, is there a way for page one.phpto automatically post values to page two.php viathe $_POST variable?

I want my form to POST to the same page, but not have the 'document expired' problem when sessions are being used somewhere in the script (when I hit press the back button in the browser). I know this can be avoided by posting to a different PHP page, and then use a header(location) to redirect, but I ideally want to keep it on the same page as I use some of the variables produced from within the processing section.    Please excuse the crude examples,   This works:

session_start();

/*HEADER*/
if(isset($_POST['test']){
    
    //do some validation
    $validated= true;
    
    if($validated){
        //process the form
        $_SESSION['notification'] = 'form submitted successfully';
        header('location: samepage.php');
        exit;
    }
    else{
        $_SESSION['notification'] = 'there was an error';
        header('location: samepage.php');
        exit;
    }
}

/*BODY*/
if(!isset($_SESSION['notification'])){
     //show the form.. posts 'test' to current page
}
else {
    echo $_SESSION['notification'];
    unset($_SESSION['notification']);
}

And this method shows the document expired when the page is refreshed...

session_start();

/*HEADER*/
if(isset($_POST['test']){
    
    //do some validation
    $validated= true;
    
    if($validated){
        //process the form
        $success = true;
    }
    else{
        $success = false;
    }
}

/*BODY*/
if(!isset($success)){
     //show the form.. posts 'test' to current page
}
else if($success){
     echo 'form submitted successfully';
}
else{
     echo 'there was an error';
}

I've read that I can edit the php.ini file to allow caching, which should solve the issue for example 2.   Is example 1 the correct way to be doing this? It's been pointed out that I shouldn't be using 'exit' so much so I'm trying to explore the correct methods
