Re: All suggestions are welcome

My approach would be to create not so much as a database but just a flat file, say tab delimited. You can read the entire thing into memory with PHP and manipulate the data as needed.

You could either run a web server locally (Macs have this already built in) or run it command-line based if suitable.

You'd want it to prompt for a username/password before proceeding.

You would write functions to add a new row of data, delete a row given an id, change a value given an id and column name, etc.

The entire project could be encrypted with PHPshadow. That's the cheapest PHP encryption I've found - only 5 Euros to encrypt (during a 48-hour period) or 0.99 if you do it online. Only thing is it is not available for Windows.

Regarding javascript encryption, remember that if the browser can see it, so can you. In other words, javascript encryption is pointless.

Re: Array ['key'] ['value'] Problem

I agree with evstevemd.

foreach ($array as $key => $value) {
  echo 'The key is '.$key.' and the value is '.$value; 
 }

$key and $value are created as part of the foreach statement.

Re: find frequency of all words in a large text file

I think this would work reasonably fast:

<?php
$filename = "/path/to/file.txt";
$handle = fopen($filename,"r");
if ($handle === false) {
  exit;
  }
$word = "";
while (false !== ($letter = fgetc($handle))) {
  if ($letter == ' ') {
    $results[$word]++;
    $word = "";
    }
  else {
    $word .= $letter;
    }
}
fclose($handle);
print_r($results);
?>

Note: This assumes the file is in the format <word><space><word><space><word>.... etc.

Re: PHP random time() function

Here I'm assuming you will be executing the code as the user logs in. So you can do this:

$random_hour = randbetween(0,23);
$current_hour = date("G",time());
if ($current_hour == $random_hour) {
  // something great happens
  }

If you're trying to implement it on a weekly cycle (i.e. choosing a random hour on a random day) then use this code when the user logs in:

$random_hour = randbetween(0,23);
$random_day = randbetween(1,7);
$current_hour = date("G",time());
$current_day = date("N",time());
if ( ($current_hour == $random_hour) && ($current_day == $random_day) ) {
  // something great happens

Re: Get Id Of an elment in onClick event

One way is to have a transparent DIV that takes up the whole screen with a high z-index value, but still lower than the sign-in DIV. On that DIV you'd have something like this:

<div onClick="cancelSignIn()">

And the corresponding Javascript:

function cancelSignIn() {
document.getElementById("signin").name=0;
document.getElementById("twitter").style.display='none';
}

A full-page DIV an be achieved by putting it after the <body> tag and applying the following CSS (assuming the DIV's id is "canceltwitter":

div#canceltwitter {
position: absolute;
margin: 0px;
padding: 0px;
border: 0px;
width: 100%;
height: 100%;
z-index: 50;
display: none;
}

You'd need to also set the z-index of the Twitter div to something greater than 50, and use javascript to set the "display" property of the canceltwitter div to block at the same time as displaying the twitter div. (Also putting the canceltwitter div's display property back to none as part of the cancelSignIn() function).

Re: calculating amount

Yes, you can for the name attribute but no not for the id attribute.
But in any event, the name attribute is never used because the form is never submitted; from what I can tell you are simply using input boxes to display information. The only reason to keep the name attribute is to produce HTML that is W3C compliant.

Re: calculating amount

You cannot have multiple tags with the same id. Your code will output multiple instances of <input id="rate"> and <input id="qty">.

You should serialise them, like this:

<script type=text/javascript>
function multiply(id){
var a;
var b;
var c;
a = document.getElementById("rate" + id).value;
b = document.getElementById("qty" + id).value;
document.getElementById("amt" + id).value = a * b;

Re: PHP Date function?

Thanks!

edwinhermann, I get this error with your code:
"Fatal error: Class 'DateInterval' not found "

You're probably on an older version of PHP. You'll need 5.3+ for my code.

You may want to try other code offered by other people, though they use "date()" which is best to avoid, so when you upgrade to PHP5.3 you may want to transition your code back to something like what I posted, using the DateTime andDateInterval classes.

Re: PHP Date function?

This code does what you've asked, and starts looking from "tomorrow".

<?php

$di = new DateInterval("P1D");
while ( ($dt -> format("l") != 'Tuesday') && ($dt -> format("l") != 'Saturday') ) {
  $dt -> add($di);
  }
echo 'Next sale: '.$dt->format("l, j F Y");

Just replace the timezone with that of your locale, and of course you can change the format of the output as well.

Re: mysql_query question

is there a way to group all of the OR's together so that the statement is true if any one of the OR statements are true.

You can use brackets to group things together.

For example:

WHERE (a = b OR c = d OR d = e) AND (f = g)

or

WHERE (a = b AND c = d) OR (e = f)

These are just a couple of random examples do illustrate the point. By using brackets, everything inside brackets is evaluated first.

THe first example requires either a to be equal to b, or c to be equal to d, or e to be equal to e, and as well as at least one of those being true, f must equal g.

The second example requires that a is equal to be and b is equal to c, or, if not the case, then e must be equal to f.

Re: Question

You state you're getting errors. What exactly are the error messages?

I can take a guess at what you're trying to achieve:
Change the five SQL lines to this:

mysql_query("DELETE FROM buddies WHERE characterid = ".$players['id']);
mysql_query("DELETE FROM inventoryitems WHERE characterid = ".$players['id']);
mysql_query("DELETE FROM skills WHERE characterid = ".$players['id']);
mysql_query("DELETE FROM keymap WHERE characterid = ".$players['id']);
mysql_query("DELETE FROM characters WHERE characterid = ".$players['id']);

I'll explain what this does:

Line 21 (in your original code listing) produces an array, with the indexes of the array being the names of the columns in your database. This array is stored in the variable $players.

Based on what you have in Line 18, the array with the key 'id' will be the ID of the player to delete.

Therefore, $players is what represents the ID of the player whose data is to be deleted.

The only thing I'm dubious about is your logic for determining which players should be purged (i.e. the WHERE clause in line 18). I don't know enough about your data to be able to say whether or not your logic is correct, but to check whether it's selecting the right players you can always insert a

print_r($players);

line after the while statement. That will show you a print out of …

In your code, $players is an array. You can't specify an array in your SQL string. So you need to reference the correct array element, such as:

mysql_query("DELETE FROM buddies WHERE characterid = $players['characterid']");

Also I noticed that line 25 has $result (which should also be $players).

Re: Regular expression

Hi,

my problem is in regular expression. I need to catch from html code hyperlink tag's href atribute content if this hyperlink contains search condition.

Here's what you want:

$a = "nail"; //search ctriteria between <a></a>
$s =<<<EOF
<a class="level2" onmouseout="this.style.background = '';" onmouseover="this.style.background ='#2c7cf4';" href="index.php?item&amp;module=1&amp;category=11" style="">  kaut kas cits </a>

<a class="level2" onmouseout="this.style.background = '';" onmouseover="this.style.background ='#2c7cf4';" href="index.php?item&amp;module=1&amp;category=15" style="">  kaut kas cits2 </a>
EOF;
//this is how far i figured it out
$regexp = "/<a[^>]*href=\\\"([^\\\"]*)\\\"[^>]*>[^<]*".$a."[^<]*<\\/a>/miU";
//finding all hyperlinks
preg_match_all($regexp, $s, $matches);
// result must be 'index.php?item&amp;module=1&amp;category=13'
print_r($matches);

OUTPUT:

Array
(
    [0] => Array
        (
            [0] => <a class="level2" onmouseout="this.style.background = '';" onmouseover="this.style.background ='#2c7cf4';" href="index.php?item&amp;module=1&amp;category=13" style="">  nails </a>
        )

    [1] => Array
        (
            [0] => index.php?item&amp;module=1&amp;category=13
        )

)

You can then just read off the match(es) from $matches[1].

So, in other words, $matches[1][0] is your first match, $matches[1][1] is your second match (if it exists), $matches[1][2] is your third match (if it exists), and so on.

Re: Retrieve all $_POST values...

Thanks! This has been informative to say the least and I apologize about the lack of details.

I DO know the names of all the variables, it's the values and the combination that I won't know.

The form is an order processing script, where the user selects one of the known products, selects if it's going to be Net30 or Credit Card, then submits information depending on Net30 or CC chosen as the payment method.

In that case you just build the logic by checking whether certain information has been submitted, e.g.

if (isset($_POST["FirstName"))

or whether it's empty:

if ($_POST["FirstName"] == "")

and other such logic.

Since I know the variables, I usually use:

<?php
$FirstName = $_POST['FirstName'];
$LastName = $_POST['LastName'];
// rest of post items...

And so on. The problem that I have with this is that I'm declaring all of the variables one-by-one and I feel that it's being far more tedious than it should be. I also feel that calling "$_POST" everytime I need it is excessive, but I may be incorrect on this one.

There are two approaches:

1. You can turn on Register Globals (see http://php.net/manual/en/security.globals.php) but I advise against it because of its security implications, and it's also just not a very clean method. Register Globals allows you to reference $_POST["abc"] as just $abc. You can probably guess the dangers of this. Also worth noting is that Register Globals is deprecated as of version 5.3.0 and removed in PHP 6.0.0, so even …

Re: Retrieve all $_POST values...

Your could should work but I don't see the link between processing the form variables at the beginning and the mailing code.

You might need to provide more information as to what you are wanting to do. The nature of your logic will determine the logic required in your code.

Just to clarify: If you know what the names of the POST variables will be you don't need the foreach loop. But (if I've understood you correctly) your form is dynamic and you don't know what the names of the variables will be, in which case the best thing to do is to use a foreach() loop.

If you DO know all the possible variable names, just that some might not be present, you can do it differently, like this:

$use_name = "";
if (isset($_POST["FirstName"])) {
  $use_name = $_POST["FirstName"];
  if (isset($_POST["LastName"])) {
    $use_name .= " ".$_POST["LastName"];
    }
  }
elseif (isset($_POST["Title"]) || isset($_POST["LastName"])) {
  $use_name = $_POST["Title"]." ".$_POST["LastName"];
  }
else {
  $use_name = "Customer";
  }

and later in your code when you send the email:

$email_message = "Dear ".$use_uame.",\nThank you for signing up to our newsletter....";
// more code to determine the rest of $email_message
if (!mail($email_to,$email_subject,$email_message,$email_headers)) {
  echo "An error occurred!";
  }
else {
  echo "We have sent you a welcome email.";
  }

That would be the best way. You'd do something like this:

    break;
    case "size":

B ==> 10.205.xxx.xxx
C ==> 10.206.xxx.xxx

how to read an IP Address, but only for 2 octet, (10.204, 10.205, 10.206)?
I want to put them on index.php, so:
if user IP come from 10.204.xxx.xxx, it will directing to: www.portalA.com,
10.205.xxx.xxx www.portalB.com

The following will work so long as there's no proxy in the way. If there is, you'll need to first check whether $_SERVER["X_FORWARDED_FOR"] exists, and if so, assign $ip that value, otherwise assign S_SERVER["REMOTE_ADDR"].

Not all proxies forward on the original IP address, in which case it will be impossible to tell the real IP address.

However, if you're on a LAN or there's no proxy, the following will work:

<?php

$ip = $_SERVER["SERVER_ADDR"];
$twoOctets = substr($ip,0,strpos($ip,".",strpos($ip,".")+1));
switch ($twoOctets) {
  case "10.204":
  header("Location: http://www.portalA.com");
  exit;
  break;
  case "10.205":
  header("Location: http://www.portalB.com");
  exit;
  break;
  case "10.206":
  header("Location: http://www.portalC.com");
  exit;
  default:
  // put code here to cover no match
}

?>

Re: php application deployment

Just to add to Chris's reply, there's also PHPshadow (http://www.phpshadow.com) if you're deploying on Linux/BSD/Mac OS servers.

Re: What is $form<<<POST

That's a short way of assigning a variable a value that spans multiple lines and includes special characters that would normally interfere with the PHP language.

It's called NOWDOC (see http://www.php.net/manual/en/language.types.string.php#language.types.string.syntax.nowdoc)

Consider this example:

$text = <<<SPECIAL_LABEL
The quick brown
fox jumps over
the lazy dog.
SPECIAL_LABEL

This assigns the sentence (including line breaks) to the variable $text.

The syntax is:

$variable = <<<LABEL
contents go here....
LABEL

So, in your example, the value stored in $post is:

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

Re: Try Catch Syntax Error

You forgot a } before "catch". Try:

function connect($db_host,$db_database,$db_user,$db_pass) {
global $db_connection;
try {
  $db_connection = mysql_connect($DB_HOST,$db_user,$db_pass, true);
  if(!$db_connection) {
    throw new Exception('MYQSL Connection Database Error: ' . mysql_error());
    }
  else {
    $connection = true;
    }
  }
catch (Exception $e) {
  echo $e->GetMessage();
  }
}

Re: indented subcategory recursive loop

Hello, I'm working on a recursive loop subcategory system. The code below is ALMOST where I need it. The last thing I'd like to do is indent each subcategory based on levels deep, rather than just separate by commas. I can't seem to wrap my head around it. Any suggestions?

Not sure if you're wanting to return HTML code or plaintext.

Try this for plaintext:

function showlist($parent, &$catlistids="",$depth = 0) {
  $result = mysql_query("SELECT component_part_id, component_part_quantity_used FROM builds WHERE build_part_id='$parent'");
  while ($line = mysql_fetch_array($result)) {
    for ($i=0;$i<$depth;$i++) {
      $catlistids .= "  ";
    }
    $catlistids .= get_part($line["component_part_id"]) . ' ' .  $line["component_part_quantity_used"]."\n";
    showlist($line["component_part_id"], &$catlistids,$depth+1);
  }
return $catlistids;
}

Or for HTML:

function showlist($parent, &$catlistids="",$depth = 0) {
  $result = mysql_query("SELECT component_part_id, component_part_quantity_used FROM builds WHERE build_part_id='$parent'");
  while ($line = mysql_fetch_array($result)) {
    for ($i=0;$i<$depth;$i++) {
      $catlistids .= "&nbsp;&nbsp;";
    }
    $catlistids .= get_part($line["component_part_id"]) . ' ' .  $line["component_part_quantity_used"]."<br>";
    showlist($line["component_part_id"], &$catlistids,$depth+1);
  }
return $catlistids;
}

Re: Problem resetting 2D array. (After foreach loop?)

foreach ($rows as $rows) is invalid - you can't use the same variable name twice.

Try this:

$result = $database->query('SELECT * FROM testtable ORDER BY timestp DESC;');
		
$rows = array(array());

while ( $tmp = $db->fetch_assoc( $result ) )
  {
  $rows[] = $tmp;
  }
		
foreach ( $rows as $row)
  {
  echo '<br />';
  echo $row['id']." --> ".$row['timestp']." --- ".$row['val'];
  }

reset($rows);

Re: Basic security question

It's difficult to know your setup, so I'm only guessing, but one possibility is that your server doesn't accept short tags.

I notice that in process.php, after <body> you open your PHP code with <?

Try using <?php instead.

You need to get it such that if someone browses to http://yoursite/process.php, the code does NOT show up. If it's not fixed by my suggestion, I suspect it's a server setting somewhere.
