The following will allow for you to post PHP in your widgets:
Place in your functions.php file
Appearance > Editor > Theme Functions (functions.php)
Written by
add_filter('widget_text', 'php_text', 99);
function php_text($text) {
if (strpos($text, '<' . '?') !== false) {
ob_start();
eval('?' . '>' . $text);
$text = ob_get_contents();
ob_end_clean();
}
return $text;
}
Now you can place php code so long as its within its <?php and ?> tags.

Just starting to make a note of some of my CSS creations:

Here’s a quick little tip I’ve been using recently with the new year having rolled around. I’ve started replacing all of my © 2011 code with the following. This will always return the date of the current year. That way you don’t have to remember to update it all over the place every time we “celebrate” a new year.
<?php echo date('Y'); ?>
So now I don’t ever have to update this post and the current year should always be reflected here: 2012
Hey again all, for this post I’ll be covering how to populate a PHP/HTML table by way of looping through a table in mysql. I’ll be using the sample database provided by http://www.mysqltutorial.org/mysql-sample-database.aspx which has to do with models (cars, planes, ships, etc). Everyone has differing levels of knowledge so I’ll be including some basics as well such as connecting to the mysql database (and closing it later on).
The table we’ll be using in the database is ‘products’. It has the following columns:
productCode - A unique inventory number productName - Name of the product productLine - Basic descriptor, 'Motorcycles', 'Classic Cars', etc productScale - This models scale size productVendor - Company that built the model productDescription - Detailed description of product quantityInStock - Current number of quantity in stock buyPrice - Listed price on the "website" MSRP - Manufacturers Suggested Retail Price
If I know I’m going to be using my mysql database in multiple files I’ll always throw the connection in something like a ‘dbconnect.php’ file. Here’s an example:
<?php
mysql_connect("localhost", "MYSQL_USERNAME", "MYSQL_PASSWORD") or die(mysql_error());
mysql_select_db("MYSQL_TABLE") or die(mysql_error());
?>
Now you can include this in every file, or better yet in your header file which will get included everywhere else. So for example in your header.php file you could throw in:
<?php
require_once('dbconnect.php');
?>
Alright, so now you’ve got your connection to your database and the appropriate database selected. We’ll skip over the other content that you want to eventually add and say (for this example) that we want to list all of our models. We’ll look at doing this a few different ways, first off we’ll go simple and just request everything from the database and then we’ll tell php how to spit that all out to us.

The following can be used to test for different criteria in passwords.
<?php
$min = 6;
$max = 20;
$password = $_POST['password'];
$confirmpw = $_POST['confirmpw'];
if($password != $confirmpw){
$error .= "Password and Confirm password do not match! <br />";
}
if( strlen($password) < $min ) {
$error .= "Password too short! <br />";
}
if( strlen($password) > $max ) {
$error .= "Password too long! <br />";
}
if( !preg_match("#[0-9]+#", $password) ) {
$error .= "Password must include at least one number! <br />";
}
if( !preg_match("#[a-z]+#", $password) ) {
$error .= "Password must include at least one letter! <br />";
}
if( !preg_match("#[A-Z]+#", $password) ) {
$error .= "Password must include at least one CAPITAL! <br />";
}
if( !preg_match("#\W+#", $password) ) {
$error .= "Password must include at least one symbol! <br />";
}
if($error){
echo "Password Failure: $error";
} else {
// Code to execute on success.
}
?>
The following can be used to clear a value. I regularly use this for website search bars.
onclick="this.value=''"
Of course if you wanted to you could also have it change the value to something else instead of blanking it out.
onclick="this.value='New Value'"
The following will allow you to export your mysql queries from mysql to a csv file that can be opened in several spreadsheet softwares. You may need to change the , (comma) to a ; (semi-colon) depending on your software.
A note for those of you using my osTicket Reports MOD: This is not what I’m using for that.
<?php
$host = 'localhost';
$user = 'userName';
$pass = 'password';
$db = 'databaseName';
$table = 'tableName';
$file = 'export';
$link = mysql_connect($host, $user, $pass) or die("Can not connect." . mysql_error());
mysql_select_db($db) or die("Can not connect.");
$result = mysql_query("SHOW COLUMNS FROM ".$table."");
$i = 0;
if (mysql_num_rows($result) > 0) {
while ($row = mysql_fetch_assoc($result)) {
$csv_output .= $row['Field'].", ";
$i++;
}
}
$csv_output .= "\n";
$values = mysql_query("SELECT * FROM ".$table."");
while ($rowr = mysql_fetch_row($values)) {
for ($j=0;$j<$i;$j++) {
$csv_output .= $rowr[$j].", ";
}
$csv_output .= "\n";
}
$filename = $file."_".date("Y-m-d_H-i",time());
header("Content-type: application/vnd.ms-excel");
header("Content-disposition: csv" . date("Y-m-d") . ".csv");
header("Content-disposition: filename=".$filename.".csv");
print $csv_output;
exit;
?>
<?php
// The letter l (lowercase L) and the number 1
// have been removed, as they can be mistaken
// for each other.
function RandomPass() {
// Comment the first line to exclude special characters
$chars = "!@#$%^&*";
$chars .= "abcdefghijkmnopqrstuvwxyz023456789ABCDEFGHIJKLMNOPQRSTUVWXYZ";
srand((double)microtime()*1000000);
$i = 0;
$pass = '' ;
while ($i <= 7) {
$num = rand() % strlen($chars);
$tmp = substr($chars, $num, 1);
$pass = $pass . $tmp;
$i++;
}
return $pass;
}
// Usage
$password = RandomPass();
echo "Random password is: $password";
?>
This is information on removing the c99madshell hack that can get into some Joomla 1.5 sites. Most of this content is an original article of News Blog. I was only able to find one portion of this myself before finding their article, kudos and thanks go to them.
If you see the following Joomla error appearing on most Joomla pages including admin section

If you have a list of spam links
then your installation has likely been compromised. There is a security bug in Joomla 1.5 allowing a hacker to reset your admin password.
You should take the following steps to get rid of the error message and secure your Joomla:
