PHP - Strange Problem!!!only Work After A Refresh!

Hi all!

Firstly, I'd like to say a big hello to everyone

Right, so I have a bit of a strange problem.  I get no error, but my page stalls.

So here's what I've got, a simple alphabet (A-Z) in capitals at the top of the page, created by:


$alphabet = array('A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z');

// then further down the page I have it looped as so:
<?php foreach($alphabet as $link): ?>
    <a href="suppliers.php?filter=<?php echo $link; ?>">
        <?php echo $link; ?>
    </a> | 
<?php endforeach; ?>


So that's all cool.  I then have this at the top of the page:


$the_suppliers = (isset($_GET['filter']) && preg_match("/[^A-Z]*/",$_GET['filter'])) ? $suppliers -> get_all($_GET['filter']) : $suppliers -> get_all('all');



Now I have preg_match() in there as I was using ctype_alpha() to check for only alphabetical chars, and thought that might be my problem, but still get it with preg_match();

Anyway, my class method (get_all()) is:


                    public function get_all($filter){

global $database;

if($filter == 'all'){

$sql = "SELECT * FROM " . self::$table . " WHERE on_web = 1 ORDER BY RAND() LIMIT 10";

}else{

$sql = "SELECT * FROM " . self::$table . " WHERE on_web = 1 AND LEFT(name,1) = '" . $database -> sql_prep($filter) . "'";

}

return self::find_by_sql($sql);

}


Now this works fine for b-z, but for some reason when the filter=A it just hangs.....  I have ran the sql in phpmyamin and it returns the result straight away, so I know it's not the sql.

Does anyone here know where I might be going wrong here?  It's very odd and I've never come across this before, and not getting an error doesn't really help much.

Any suggestions or pointers will be gratefuly received

Hi. I have to check if a session is started or not, and then, check for the rank of the user. For that i use two functions like is_administrator,etc.

Well, but this isnt working. I cant get any clear way to know if a session have been already started or not.
Code: [Select]
function is_administrator() {
session_start();
if (isset($_SESSION['usr']) and empty($_SESSION['usr'])) {

$l = conect();
$user = $_SESSION['usr'];
$cons = "SELECT * FROM `users` WHERE usr='" . $user . '\';';
$res = mysql_query ($cons,$l);
$ob = mysql_fetch_array($res);

if ($ob['tipo'] == 'A') {
return true;
}

}
return false;
}

What i want to do is to check if a sesion exist, if not, return false. If the sesion exist, check for the user rank and return true/false.

Hi,

I get this error when I load the page, but after hitting ctrl f5 to refresh.. the error goes away and the page works perfectly.  I have edited out my details.

Warning: mysql_connect() [function.mysql-connect]: Access denied for user 'user'@'localhost' (using password: YES)
Access denied for user 'user'@'localhost' (using password: YES)

I know everything is set right.. I just don't get it.. I am going crazy of this. Ive cleared my browser cache.. even tried it on my android phone and it does the same thing.

Thanks,
Deceevn

$comment = $_POST["UserComment"];

$sql="INSERT INTO comments (name, email, comment)VALUES('$name', '$email', '$comment')";
$result=mysql_query($sql);


?>

Hi,
I was using latest php5 but as I couldn't find a ffmpeg-php extension for it, I actually swapped to latest php4, and now I'm having a problem when using fopen for urls, when it's used it just stops the script with no error / warning, i tried using the same php.ini used with my php5 too but it changes nothing.
Btw allow_url_fopen is enabled.
Thanks if someone can help.

Hi folks,

I have an initial redirect page which directs to my main page, sending two reference variables as $_GET parameters:

Code: [Select]
header("Location: /ob/index.php?id=".$id."&ref=".$ref);
The first thing this main page does is include a file which checks for those two values:

Code: [Select]
if (substr_count($_SERVER['HTTP_ACCEPT_ENCODING'], 'gzip')) ob_start("ob_gzhandler"); else ob_start();
session_start();
error_reporting(E_ALL);

if (isset($_GET['id']) && isset($_GET['ref'])){
$_SESSION['id'] = $_GET['id'];
$_SESSION['ref'] = $_GET['ref'];
}
if(!isset($_SESSION['id']) || $_SESSION['id']=="" || !isset($_SESSION['ref']) || $_SESSION['ref']==""){
echo ("This service requires a valid ID to run - your session may have expired, please refresh your browser to try again.");
exit;
}
The main page loads fine - meaning that the $_SESSION variables have been set correctly. However, when the next page loads (including the same file), the $_GET values obviously aren't there but the $_SESSION variables should be intact. I am getting fails every time though in Opera and Safari (have checked in IE, FF and Chrome and all seems well).

However, if I then refresh the browser - in both Opera and Safari - the next page loads fine and the $_SESSION variables are correctly set.

Any ideas on this at all?

Many thanks in advance,

Rich

Hi Guys
First sorry for my bad english.

I have a strange problem with php upload form.

When i click on submit button ( with uploaded pdf ) nothing happens.
The pdf file is 17MB, but with smaller PDF the form works perfectly.

Here is the form code:

Code: [Select]
<form id="pdf" name="pdf" method="post" action="" target="_self" enctype="multipart/form-data" >
<p align ="center">
        <input type="hidden" name="app_id" value="<?php print $app_id?>">
        <input type="hidden" name="MAX_FILE_SIZE" value="1000000000000">
        <input type="file" name="file1" value="Upload PDF" device="files" accept="text/pdf" />
        <input type="submit" name="sent" value="Send" />
</p>
</form>
at the beginning of the upload.php i have the following lines:

Code: [Select]
$sent = isset($_POST['sent']) ? $_POST['sent'] : false;
When i debug $sent and $_POST i saw that they are empty  : (

With smaller PDF works perfectly but now with 17MB pdf $sent is empty,the result from print_r($_POST) is Array()

in php.ini i changed MAX UPLOAD to 20MB  and then restarted my apache , but i think this doesn't matter.

This problem is very strange : )

Thanks in advance:)

Friends
this is a very strange problem i,m facing
i made a form by which you can enter comments to a topic
i get the comment title and comment topic and date and the name and e mail of the one who insert a comment
according to these variables


$id1=$row2['id'];
echo "$id1";
//Comment poster,s name
$name =strip_tags(@$_POST['coname']);
//Comment title
$title =strip_tags(@$_POST['comtitle']);
//ment poster,s email
$mail =strip_tags(@$_POST['comemail']);
//comment
$com =strip_tags(@$_POST['limitedtextarea']);
//comment,s date
$d= date("Y-m-d");
notice that i,m printing the topic id and i used the variable $id1 to get it inorder to use it to show the comments for this topic later and it shows the right id for the shown topic
then i used this code to insert these variable into the database
if(isset($_POST['add']) and $_POST['add']=='comm'){

$insertcomm =mysql_query("INSERT INTO comments
(com_name,com_title,com_mail,comment,com_date,tid)
VALUES
('$name','$title','$mail','$com','$d','$id1')") or die("comments were not inserted");
if(isset($insertcomm)){
echo "comment inserted ";}
}

I am trying to do isset($_GET but I have a bizarre problem come up.  I am using "id" as one of my fields but when I try to use it in the code it says it is not recognised.  However I use this field quite widely.

The code its coming up with is "Undefined variable: id" but I cant see why it has a problem with id.

My code is:

<?php

if(isset($_GET['id'])){

$sql = mysql_query("SELECT * FROM productfeed WHERE id='$id' LIMIT 1");

}
{


while($row = mysql_fetch_array($sql))

$id = $row['id'];
$image = $row['awImage'];
$link = $row['link'];
$description = $row['description'];
$fulldescription = $row['fulldescription'];
$price = $row['price'];

echo "<div class=\"productdisplayshell\"> <div class=\"productdisplayoutline\"> <div class=\"productborder\"><center>  <a href=\"$link\"  target=\"_blank\" ><img src=\"$image\" /></a> </center> </div></div> <div class=\"productdescriptionoutline\"><div class=\"productdescriptionbox\">  <a href=\"$link\"  target=\"_blank\" >$description</a> </div><div class=\"productfulldescriptionbox\">  $fulldescription </div></div> <div class=\"productpriceoutline\">  <div class=\"productpricebox\"><center>&#38;#163; $price</center></div>  <div class=\"productbuybutton\"><center><a href=\"$link\"  target=\"_blank\" ><img src=/images/buybutton.png /></a></center></div></div></div>";

}

Hi,
I've done a search and cant find anything related to my problem.
I have a newsfeed on my site and i want it to display with the latest news at the top.
I have this code:
Code: [Select]
$get_news = "SELECT title, text, DATE_FORMAT(datetime, '%e %b %Y at %T') AS datetime FROM newsfeed ORDER BY datetime DESC";
This works fine on one of my sites but on another i've just hit a problem. It seems to sort only by the day, not the rest of the date.
I made a news post today with date and time of "27 Mar 2011 at 12:54:02" but a post from "28 Jan 2011 at 19:59:52" is above it.

Any ideas why this is happening?

Thanks,
Alex

I submit text to my MySQL database using a form on my site. When I look at the text in my database, sometimes, there are strange characters. The strange characters are caused by quotation marks, em dashes, apostrophes and foreign letters of the alphabet. I think that this only happens when the source of the text is a Windows program. I understand that this is a character encoding issue, but I don't fully understand the subject. I've spent the last few hours researching it, but it's only confused me.   My site uses UTF-8 encoding:

<meta http-equiv="content-type" content="text/xml; charset=utf-8" />

The collation of my database is utf8_general_ci.   My form looks like this:

<form action="" method="post">
</form>

As you can see, an accept-charset="utf-8" attribute has not been specified.     Questions   1) I am guessing that my problem is that the Windows characters are being misinterpreted by my UTF-8 setup. Is that correct?   2) If so, is there a way that I can safely convert the Windows characters to UTF-8 during the submission process?   3) Should I also specify an accept-charset="utf-8" attribute on the form?   4) When I paste the Windows text directly into my database without using the form, the characters save without turning into the strange characters. But they don't render properly on my site. Can't browsers identify Windows characters?
