Hi I'm currently using a header to retrieve some info

$prof = $_SERVER["HTTP_X_MXIT_PROFILE"];

It output the value as

en,ZA,1991-01-30,Male,1

I'm trying to use the 1991-01-30 from the above output to calculate if the person is 18 years of age or older

Any suggestions on how to do this I tried to put it into an array but was unsuccessful...

September 23, 2015

You would call your function like any other function
$this->ip = getUserIP();
Or if getUserIP is a method for your poll class then it'll be
$this->ip = $this->getUserIP();

Ah thank you I see I had the same function on both pages and got redeclare error so I fixed it

September 23, 2015

Hi I got two functions and I want to use the 2nd function within the first function is this possible

Function 1

class poll {

    public $db;
    public $tbl;
    public $pollvars;
    public $poll_view_html;
    public $poll_result_html;
    public $options;
    public $options_text;
    public $poll_question;
    public $form_forward;
    public $template_set;
    public $ip;

    public function __construct() {
        global $POLLTBL, $CLASS;
        $this->tbl = $POLLTBL;
        $this->poll_view_html = array();
        $this->poll_result_html = array();
        $this->options = array();
        $this->options_text = array();
        $this->poll_question = array();
        $this->form_forward = basename($_SERVER['PHP_SELF']);

        $this->ip = getenv("REMOTE_ADDR");
        $this->db = &$CLASS["db"];
        $this->pollvars = $this->db->fetch_array($this->db->query("SELECT * FROM ".$this->tbl['poll_config']));
        $this->template_set = "default";
        
        if ($this->pollvars['result_order'] == "asc") {
            $this->pollvars['result_order'] = "ORDER BY votes ASC";
        } elseif ($this->pollvars['result_order'] == "desc") {
            $this->pollvars['result_order'] = "ORDER BY votes DESC";
        } else {
            $this->pollvars['result_order'] = '';
        }
    }

Function 2

function getUserIP()
{
$mxitidun = $_SERVER['HTTP_X_MXIT_DEVICE_ID'];
    $client  = @$_SERVER['HTTP_CLIENT_IP'];
    $forward = @$_SERVER['HTTP_X_FORWARDED_FOR'];
    $remote  = $_SERVER['REMOTE_ADDR'];

    if($mxitidun != '')
    {
        $ip1 = $mxitidun;
    }

    elseif(filter_var($client, FILTER_VALIDATE_IP))
    {
        $ip1 = $client;
    }
    elseif(filter_var($forward, FILTER_VALIDATE_IP))
    {
        $ip1 = $forward;
    }
    else
    {
        $ip1 = $remote;
    }

    return $ip1;
}

I'm trying to Use the line in function 1

$this->ip = getenv("REMOTE_ADDR");

and replace getenv("REMOTE_ADDR"); with the function output value of Function 2

I think I see what you want now. You need to find the highest id associated with each topic and sort on that.

$sql = "SELECT topic
        , description
        , topid
        FROM news
            INNER JOIN
            (
            SELECT topic
            , MAX(id) as topid
            FROM news
            GROUP BY topic
            ) tid USING (topic)
        ORDER BY topid DESC, id ASC";
$res = $db->query($sql);

$prevtopid = '';
while ($row = $res->fetch_assoc()) {
    if ($prevtopid != $row['topid']) {
        echo "<b>{$row['topic']}</b><br>";
        $prevtopid = $row['topid'];
    }
    echo " - {$row['description']}<br>";
}

Thank you, I figured another way aswell just now. I added another field in my database named rank(numbers) and add a a new value each time into the field each time I create a topic and changed my display loop to work with the rank instead of the topics. But I'm going to use the above code

September 21, 2015

Exactly.

So there isn't a way to sort it by ID?

Here Is my current display page...

So basically I want my topics column to be ordered DESC according to ID and my News column ordered ASC

September 21, 2015

ORDER BY topic, id DESC

or, if you want topics descending too,

ORDER BY topic DESC, id DESC

The thing is it still order the topics column first, I want to sort the ID column first and then the topics column, but if I change it to

ORDER BY id DESC, topic

my topics and descriptions isn't grouped no more?

September 21, 2015

prev = '';
while fetch next row
  if prev != topic
    output topic
    prev = topic
  endif
  output news
endwhile

Thank you @Barand I got it working

      $lasttopic = $myrow['topic'];
   }
 print "<p>* " . $myrow['news'] . " - " . $Editnews . " | " . $delete . "<br></p>";

 }

Just a question since im ordering it by Topic how will I add Descending order by id to show the latest topic and description at the top?

I'm getting the output

How to show it as

1

* 99

* 100

2

* 1000

* 2000

$sql = "SELECT * FROM News ORDER BY topic";
$result1 = mysql_query($sql, $db)or die($sql."<br/><br/>".mysql_error());


while($myrow = mysql_fetch_array($result1))
{
print $myrow['topic'] . " - " . $Editnews . "<br>";
print $myrow['news'] . " - " . $Editnews. "<br>";


}

Any assistance please?

If 1 and 99 and 1000 and 2000 all are the same field and are NUMERIC (not text) that will be difficult.

I used 1 and 2 as the topics and 99 and 100 as the description of 1(topic) and 1000 and 2000 description of 2(topic)

GROUP BY in the query doesn't do that. it consolidates the rows having the same group value into a single row. it's primarily used when you want to use aggregate functions (sum, count, ...) on the data in the group.

to do what you are asking, you would order (use ORDER BY topic) the rows in the result set to get the rows for the same topic together, then when you are outputting the data, each time the topic value changes you would close out the previous topic section and start a new topic section.

I'm getting the output

1 - Edit News

99 - Edit News

1 - Edit News

100 - Edit News

2 - Edit News

1000 - Edit News

2 - Edit News

2000 - Edit News

How to show it as

2

* 1000

* 2000

$sql = "SELECT * FROM News ORDER BY topic";
$result1 = mysql_query($sql, $db)or die($sql."<br/><br/>".mysql_error());


while($myrow = mysql_fetch_array($result1))
{
print $myrow['topic'] . " - " . $Editnews . "<br>";
print $myrow['news'] . " - " . $Editnews. "<br>";

Hi I have the following fields in my database table

id - int

topic - varchar

news - varchar

What im trying to do is group the topics ex

topic1 - 123

topic2 - 987

topic1 - 456

topic2 - 654

I want to show it as

Topic 1

* 123

* 456

Topic 2

* 987

* 654

seems like I'm going wrong somewhere...

$sql = "SELECT * FROM News GROUP BY topic";
$result1 = mysql_query($sql, $db)or die($sql."<br/><br/>".mysql_error());


while($myrow = mysql_fetch_array($result1))
{
print $myrow['topic'] . " - " . $Editnews . "<br>";
print $myrow['news'] . " - " . $Editnews. "<br>";


}

Hi I'm trying to find a script where I can create my own topics and descriptions to use as a news page or notification board

with the layout like

Heading 1 - Edit | Delete | Down

Description 1 - Edit | Delete | Down
Description 2 - Edit | Delete | Up | Down
etc...

Heading 2 - Edit | Delete | Up

Description 1 - Edit | Delete | Down
Description 2 - Edit | Delete | Up | Down
etc...

etc...

It should be able to add as many headings and descriptions as you wish ad an option next to each one to edit the heading or description

Does anyone know of a sortlike script?

Hi I'm trying to create a mute function

My Database table layout:

ID int AI

word varchar 30

I got 260 words in my table now I'm trying to check my $_POST['message'] string to see if any of these words are in the string and if it does it should insert a 10 min mute

				
                                    $resultmute = mysql_query("SELECT word FROM StringyChat_WordBan") or die(mysql_error()); 
$rowmute = mysql_fetch_assoc($resultmute);
if (stristr($message,$rowmute['word']) !== false) {
$expire = time() + (60 * 10);

          $querymute = "UPDATE timeban SET user='$name', bantime='$expire', banby='ADMIN'  WHERE mxitid='".$mxitid."'"; 
      mysql_query($querymute);
			

}

The current problem I have is I want to check case insensitive characters. For instance if I got the word "badwords" in the database and the word is spelled "Badwords" it should still be considered a bad word. At the moment it seems like only certain words in my database get filtered and the rest not...

My second question is regarding the replacing of the word with this function

function filterBadWords($str)
{
	
	
    $result1 = mysql_query("SELECT word FROM StringyChat_WordBan") or die(mysql_error()); 
    $replacements = "x";
    
    while($row = mysql_fetch_assoc($result1))
    {
          $str = preg_replace('/\b' . $row['word'].'\b/i', ':-x', $str);
    }  
    
    return $str;
}

Is there a way to check if theres another letter next to the word and if so not to filter it. for example assassinate will be filtered to :-x:-xinate but I want to check if there is some character at the end or the beginning of the same word not to filter it...

September 19, 2015

Hi I'm currently having a syntex error with my bad words filter function

function filterBadWords($str)
{
	
	
    $result1 = mysql_query("SELECT word FROM StringyChat_WordBan") or die(mysql_error()); 
    $replacements = "x";
    
    while($row = mysql_fetch_assoc($result1))
    {
          $str = preg_replace('/\b' . $row['word'].'\b/ie', ':-x', $str);
    }  
    
    return $str;
}

Parse error: syntax error, unexpected ':' in /home/u342037492/public_html/chat2/page.php(1917) : regexp code on line 1

Fatal error: preg_replace(): Failed evaluating code: :-x in /home/u342037492/public_html/chat2/page.php on line 1917

I know its the :-x part causing the problem but how can I fix it?

and is there maybe a better way to do the filter because if I got the word "ass" in my list it will replace assassinate to :-x :-xinate ?

Hi I'm trying to create an array to put it into a string like the following



$marray = array(

    '1' => 'apple,',

    '2' => 'orange,',

    '3' => ' ',

    '4' => ' ',

    '5' => 'apple');

And the string should look like



       $mrules = "Welcome Moderator please read the following rules. " . 1. Apple, 2. Orange, 5. Apple.

The empty values in the array shouldn't be showed

any assistance please

Oops! typo. Remove the "pm" after "ON"

UPDATE pm

INNER JOIN Users2 u ON pm u.mxitid = pm.ip

SET pm.username = u.username

Thank you that solved the problem just learned something new with this query

August 24, 2015

UPDATE pm
INNER JOIN Users2 u ON pm u.mxitid = pm.ip
SET pm.username = u.username

I tried it

$updatename = "UPDATE pm
INNER JOIN Users2 u ON pm u.mxitid = pm.ip
SET pm.username = u.Username";
    mysql_query($updatename) or die("Error: ".mysql_error());

getting error

Hi I'm trying to compare two tables with each other and update the 2nd table with the new updated name from table 1 via their unique identical ID

$resultus = mysql_query("SELECT * FROM Users2");

        $rowus = mysql_fetch_array($resultus);
         $naamus = urldecode($rowus['Username']);
         $mxitus = $rowus['mxitid'];
$resultnup = mysql_query("SELECT * FROM pm");

        $rownup = mysql_fetch_array($resultnup);
         $naamup = $rownup['username'];
         $ipup = $rownup['ip'];

while($ipup == $mxitus){

$updatename = "UPDATE pm SET username= \"$naamus\" WHERE ip = \"$mxitus\"";
    mysql_query($updatename) or die("Error: ".mysql_error());
}

The $mxitus and $ipup is the 2 fields that would be identical in both tables now Im trying to update the pm table username field with the naamus field from Users 2 any assistance please?

August 23, 2015

$read1 = "unread";



$query = "INSERT INTO pm (username,mxitid,message,time,read,ip) VALUES (\"$naam\",\"$ip1\",\"$message\",\"$date\",\"$read1\",\"$banby2\")";
I'm getting the error

This only happened when I added the read and value $read I got the field named read in my database.... any suggestion where im going wrong?

If I remove the read field the rest of the query works 100%

Never mind did some further research and found that read is a reserved word had to change it to `read`

August 23, 2015

$read1 = "unread";



$query = "INSERT INTO pm (username,mxitid,message,time,read,ip) VALUES (\"$naam\",\"$ip1\",\"$message\",\"$date\",\"$read1\",\"$banby2\")";

I'm getting the error

Invalid query: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'read,ip) VALUES (\"$naam\",\"$ip1\",\"$message\",\"$date\",\"$read1\",\"$banby2\' at line 1

getimagesize

Try processing it as if it were a jpeg file. That worked for me after downloading

Isn't there a way to change the file type to the right one before processing it? because doing it manually is a pain?

August 15, 2015

$img (the second parameter in imagecopyresampled) is false because of the first error message - not a valid png file.

This is the image I tried to upload attached

how should I go on fixing the problem because it seems all png files bigger than 100kb end up being black after the resizing aswell
