How to Remove the Default Image Link in WordPress?

you know that when you upload an image to WordPress media library, it creates multiple copies of the image in different image sizes. By default it adds a link to the image file. You can set this default link to none to remove the link, but doing it manually each time you upload an image is a little annoying. It is also annoying for users to click on an image and find the same image on the media page as well. Add this code in your theme’s functions.php file to remove default image link functionnality.

function wpb_imagelink_setup() {
$image_set = get_option( 'image_default_link_type' );

if ($image_set !== 'none') {
update_option('image_default_link_type', 'none');
}
}
add_action('admin_init', 'wpb_imagelink_setup', 10);

Program to find prime numbers in between a range of 100

Prime Number example in PHP. We will print the prime number between a range of 100.The prime number is not divisible by 2 only divisible by 1 and itself.

Example

<html>
<head>
<title>PHP Prime Numbers</title>
</head>
<body>
<?php
error_reporting(E_ALL);
//Program to find prime numbers in between a range of 100
$num =100;
for( $j = 2; $j <= $num; $j++ )
{
for( $k = 2; $k < $j; $k++ )
{
if( $j % $k == 0 )
{
break;
}
}
if( $k == $j )
echo "Prime Number : ", $j, "<br>";
}
?>
</body>
</html>

Output

Prime Number : 2
Prime Number : 3
Prime Number : 5
Prime Number : 7
Prime Number : 11
Prime Number : 13
Prime Number : 17
Prime Number : 19
Prime Number : 23

Reverse String, without strrev()

In this example we have discus how to print Reverse String, without strrev() function .Fist off all we Assign the given string to the variable and Calculate the length of the string. We use Iterate the string using for loop with appropriate looping and count Concatenate the string inside the for loop. you can see below example.

Example

<html>
<head>
<title>Reverse</title>
</head>
<body>
<?php
$string = 'Hello php';
$length = strlen($string);
for ($i=($length-1) ; $i >= 0 ; $i--) {
echo $string[$i];
}
?>
</body>
</html>

Output: php olleH

PHP strrev() Function

We can also print without loop

< html>
<html>
<body>

<?php
echo strrev("Hello World!");
?>

</body>
</html>

How to reverse a number in php without built(strrev()) in functions

In this example First off all we get the given number and extract the final digit. Initially the reverse of the number will be zero, on each iteration multiply the reverse with 10 and add the modulus result.you can see below example.

Example

<html>
<head>
<title>reverse number</title>
</head>
<body>
<?php
$number = 1234; $x =0; $y =0;
$originalnum = $number;
while($number > 1) {
$x = $number %10;
$y = ($y * 10)+ $x;
$number = $number /10;
}
Echo "Original Number: ". $originalnum;
Echo " Reverse : ". $y;
?>
</body>
</html>

Output: Original Number: 1234 Reverse : 4321

Insert Data From a Form Into a Database

User Registration Form with DataBase

In this example we have discus how to Insert Data From a Form Into a Database. First all we have created HTML From and we display some "text" fields and radio Button. we have also use form validation and we use JavaScript function which is called on checkForm(form).when we click the submit button in the HTML From,the form data is sent to "insert.php".The "insert.php" file connects to a database, and retrieves the values from the form with the PHP $_POST variables.Then, the mysqli_query() function executes the INSERT INTO statement, and a new record will be added to the "Persons" table.

Example

form.html

<html>
<head>
<title>User Registration Form</title>

if (email == "" || atpos < 1 || ( dotpos - atpos < 2 ))
{

form.emailid.focus() ;
return false;
}
if(form.pwd1.value != "" && form.pwd1.value == form.pwd2.value) {
if(form.pwd1.value.length < 6) {

Introduction to C++

Introduction to C++

Hi! Welcome to my beginners guide to C++. If you are starting to program for the First time. C++ is an excellent Language to start programming in – a lot of applications that you use are probably written in C++ and once you learn some basic concepts, learning other languages, like java for example, will be much easier.

After each topic you can rearrange the code in the examples provided or make up your own code. Programming is very much a practical subject so you will learn a lot by messing about with code or even looking at other people’s code.

Multidimensional Array

Today we are going to discus multidimensional array. A multidimensional array is an array containing one or more arrays.In this example we have used multidimensional arrays.

Example

<!DOCTYPE html>
<head>
<title>Multidimensional Array</title>
</head>

<body>
<?php
$cars= array
    (
    array("Honda",1000,100),
    array("BMW",60,59),
    array("Toyota",120,100)
    );
echo $cars[0][0].": Ordered: ".$cars[0][1].". Sold: ".$cars[0][2]."<br>";
echo $cars[1][0].": Ordered: ".$cars[1][1].". Sold: ".$cars[1][2]."<br>";
echo $cars[2][0].": Ordered: ".$cars[2][1].". Sold: ".$cars[2][2]."<br>";

?>
</body>
</html>

Output

Honda: Ordered: 1000. Sold: 100
BMW: Ordered: 60. Sold: 59
Toyota: Ordered: 120. Sold: 100

PHP Data Types

PHP Data Types

Today i will teach you. how we can use PHP data types.
There are Seven types of PHP Data Types.

String.
Integer.
Floating point numbers,
Boolean.
Array.
Object.
NULL.

String Data type:-The string is a sequence of characters. we can be any text inside quotes. we have used single or double quotes. you can see below in examples
Example of String Data types:-

<html>
<head>
<title>String data type</title>
</head>
<body>
<?php 
$x= "Hello PHP";
$y= "Welcome to PHP";
echo $x;
echo "<br>";
echo $y;
?>
</body>
</html>

Output
Hello PHP
Welcome to PHP
Integer Data type:-Integer is a basic data types. We can assign which has no of fractional part to int type but int is a 2 Byte space.
Importants Rules:
Integer is a least one digit (0-9).
Integer cannot contain comma or blanks.
Integer must not have a decimal point.
Integer can be either positive or negative values.
Now we can assign a value between the above range below example. In this example we have used different variables like as negative number, hexadecimal number ,octal numbers and we have used PHP var_dump(); function returns the data type.
Example

<html>
<head>
<title>Integer Data types</title>
</head>
<body>
<?php 
$y = 4567;
var_dump($y);
echo "<br>"; 
$y = -254; // negative number 
var_dump($y);
echo "<br>"; 
$y = 0x8C; // hexadecimal number
var_dump($y);
echo "<br>";
$y = 047; // octal number
var_dump($y);
?> 

</body>
</html>

Output
int(4567)
int(-254)
int(140)
int(39)

PHP form Validation Example

PHP form Validation Example

In this example, we have discus how to use PHP Form Validation. First off all we have displayed HTML form with text fields and submit button. In this example we have used method and function. First thing we had done is to pass all variables through PHP's htmlspecalchars() function. After the we fills all input field than ,we click submit button and display all input fields values. Now we have used $_SERVER["REQUEST_METHOD"]. If the REQUEST_METHOD is POST, and submitted form. If user not submit input fields skip the validation and display a blank form.

Example of PHP Validation:

<!DOCTYPE HTML> 
<html>
<head>
</head>
<body> 

<?php

$name = $email = $gender = $address = $mobile = "";

if ($_SERVER["REQUEST_METHOD"] == "POST")
{
$name = test_input($_POST["name"]);
$email = test_input($_POST["email"]);
$mobile = test_input($_POST["mobile"]);
$address = test_input($_POST["address"]);
$gender = test_input($_POST["gender"]);
}

function test_input($data)
{
$data = trim($data);
$data = stripslashes($data);
$data = htmlspecialchars($data);
return $data;
}
?>
<h2>PHP Form Validation</h2>
<form method="post" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>"> 
<table llpadding="2" width="20%" bgcolor="99FFFF" cellspacing="2" border="1">
<tr>
<td>Name:</td> 
<td><input type="text" name="name"></td>
</tr>
<tr>
<td>E-mail:</td>

<td><input type="text" name="mobile"></td>

<input type="radio" name="gender" value="female">Female
<input type="radio" name="gender" value="male">Male</td>
</tr>
<tr>
<td>&nbsp; &nbsp;</td>
<td> <input type="submit" name="submit" value="Submit"> </td>
</tr>
</table>
</form>


<?php
echo "<h2><Your Input:</h2>";
echo $name;

PHP Form Handling

PHP Form Handling

We are going to discus How to use PHP Form Handling. In this below example we have displays a simple HTML form, and displays for Four Input Fields and submit button. After that user fills all input fields and click the submit button, the form data is send for processing to a PHP files named "Display.php". We use for post method, Post methods is send data HTTP.
