PHP - Tons Of Weird Problems

How can you prevent your browser from caching a page? I think that my news feed is being cached and is causing new posts to not be displayed even after a refresh. Eventually, the posts will show up after about 20 refreshes. I know my query is right so I didn't know if there was a way to stop page caching.

I don't really know if it is a caching issue though. I'm starting to think I just have some weird bug in my code because sometimes on refresh news feed items get removed then i'll refresh again and some will get added back in then i'll refresh again and they'll all be there. Ever heard of this happening?

tore the forum apart looking for a solution to this one.  for some reason, this is generating an 'unexpected $end' error.  this is ALL the code.  in entirety. i was just messing around getting familiar with filesystem stuff.  no short tags.  no curly brackets.  so...

Code: [Select]
<?php
$fileHandler = fopen("someFile.txt", 'w') or die ("could not create file");
$text = <<<_END
drop some text
and some stuff
plus this stuff
some other stuff

_END;
fwrite($fileHandler, $text) or die ("could not write to file");
fclose($fileHandler);
echo "File 'someFile.txt' written successfully";
?>

thanks people.  this has be stumped.  not like its complicated, eh?  and as you can see, screws up the colour coding as well... but WHY!?!?

WR!

Hey, been banging my head against the wall for a couple of hours now.
There is an If () in the code that is driving me crazy because it is not behaving like I expect it to..


foreach ( $types as $type ) {
    if ( !isset( $type->modclass ) or !isset( $type->typestr ) ) {
        debugging( 'Incorrect activity type in ' . $modname );
        continue;
    }
    $var = (string)$type->type;
    if ( $var != 'assignment&type=online' ) {

        print '<br/>' . $var . '<br/>';
        
        if ( $type->modclass == MOD_CLASS_RESOURCE ) {
            $resources[$type->type] = $type->typestr;
        } else {
            $activities[$type->type] = $type->typestr;
        }
    }
}


results in...

Code: [Select]
label

resource&type=text

resource&type=html

resource&type=file

resource&type=directory

resource&type=ims

assignment_group_start

assignment&type=upload

assignment&type=online

assignment&type=uploadsingle

assignment&type=offline

assignment_group_end

 

Notice the assignment&type=online in the output... I'm just about ready to give up as to why it is still outputting $var when it is clearly equal to the compared string?

Any ideas?

Hi all, I can't find anything about this, but maybe someone knows this.
the code below works as it should except when it is being included for some reason the filter function doesn;'t work and i get a pop up...


$string = "<script> alert('koekoek')</script>";

echo 'string = '.filter_var($string, FILTER_SANITIZE_SPECIAL_CHARS).'<br />';



-edit: the string is normally is retrieved from a $_POST['var'] like:


$query = $_POST['query'];

    echo 'query: '.filter_var($query, FILTER_SANITIZE_SPECIAL_CHARS).'<br />';


and thats when it seems to not work when included


edit2: Now i changed the code a bit and put the filter function before echoing it, and than it works... may i assume that it should not be used in the echo directly?

$query = filter_var($_POST['query'], FILTER_SANITIZE_SPECIAL_CHARS);

echo $query;

So suppose I have a mysql table like the following

           Col1  Col2  Col3
Row1: A       10     2012-3-21 13:20:09
Row2: A       12     2012-3-20 12:04:09
Row3: A       5       2012-3-20 12:03:03

I need a query which will fetch me Row1 and Row2 given that I am searching for A, if the query sees that two rows occur on the same date, it should return the latest one. Any thoughts?

Im getting a realy weird error i my page.

Quote

Parse error: syntax error, unexpected T_VARIABLE in /pathtoroot/subscribers.php on line 1


Code: [Select]
<?php
session_start();

include 'header.php';

include("connect.php");

$username = $_SESSION['username'];

$id = $_SESSION['uid'];

How on earth is there an error there lol?

I'm inserting some data from a CSV file into a database. I'm using mysql_real_escape_string to escape a string and getting some really weird output.

ex.

input string = Adobe CS5
output = \0\0A\0d\0o\0b\0e\0 \0C\0S\05

I plugged the string into mb_detect_encoding and it told me it was in ASCII and I did a bunch of searching to find out that \0 is a null byte. The only thing I can't figure out is how to convert it to something that won't give me that garbage when I run it through mysql_real_escape_string.

I tried mb_convert_encoding($str,"ISO-8859-1","ASCII") and it didn't do anything.

Anyone know something I can try??

So, I wrote a little function the other day to fetch an array of elements out of character-separated-data (like "value1|value2|value3", but then fetched into an array using explode()). The only thing is just that it isn't working at all[/]. Every time I run the function, and catch it as an variable to use it as an array, it simply outputs the word "media", with each character separated into one array-element. Could anybody figure out what's wrong with my code? (Aside from my style, I know it's horrible. I'm halfway learning OOP) Any help would be greatly appreciated.

Code: [Select]
if(!function_exists('getText')) {
function getText($item) {
$text = explode(" | ", $data["text"][$item]);
$text = Array(0=>"")+$text;

return Array(1=>$data["text"][$item]); //outputs Array(0=>"", "m", "e", "d", "i", "a")
}
}

I am having this weird session anomaly. When logged is as a regular user, all is well until I get to this one page in particular. Once I click the link to get to this page, I become logged in as someone else. The domain is consistent across, and session_start(); is present on all pages. Is there some check that I can use to figure out why this happens every time? Thanks.

Hey guys!

Well this is actually kind of a weird problem I have been having, and not too sure why I'm getting this problem. I've tried a lot of stuff, and it doesnt seem like I've been able to find a solution. I've been trying for about a month.

Anyways, I have a website created with some OOP. Well, once I write an include statement to include a file, which then includes all my classes, it messes up my font, moves my website content down, and well.. it just does weird stuff.

However, once I comment the include out, the website looks normal again.

so basically, I can comment out the file itself and everything is just fine. But it only happens when I include my class files.

Any ideas or suggestions would be amazing! Thank you!

Hi Guys/Gals,

I have a search form that people search for keywords.  Basically and one field and one button form.

When they search for a particular string for example, "white" it's only bringing up one result, but 23 times.  Here's my code:

I have a function that contains 2 UPDATE commands. One updates a table whenever the function is ran. The second updates only if a condition is met.

When the page loads the function is ran. For some reason the table is updated twice. So my table looks like this:

Initially
Viewed: 0 Replies: 0

Navigate to page:
Viewed:2 Replies:0

Enter a reply and submit:
Veiwed:4 Replies:1

No matter where I move the "viewed +1" code, it fires twice per page impression. Is this a glitch? Do functions run twice for some reason? If so why doesn't "reply +1" fire twice?



//page loads as forum.php?goto=innertopic
function connectForum(){
     //connects DB
     if($_GET['goto'] == "innertopic"){
          detailTopic();
     }
}
function detailTopic(){
     if(isset($_POST['content']{ //if there is a reply to a post
          mysql_query("UPDATE topics SET Replies=Replies+1") //works fine
     }
     else{ //no reply, just show all posts
          mysql_query("UPDATE topics SET Views=Views+1") //fires 2 times per page load .. ?!?!?
          //show posts
          //show reply window, posts to forum.php?goto=innertopic&&content=whateverTheUserTyped
     }
}

//html of page

if($_GET['goto'] == "innertopic"){
     connectForum();
}

Hello there,

I am making a function to execute every time with a new demand no. in the while loop below. Every thing goes fine for the first time when the page loads, all the taxes come perfectly and each record is being read with the function calculateTaxes($demandno). But, when I press the search button with blank entries... All the entries come with only the first record. Means, the calculateTaxes function is not being loaded again and again with the loop when the press the search button.

Please help.

Please have a look in the below given code:
