How to display Result in textbox in PHP

How to get input from HTML, do calculation and display output in text box.

Write a program to add two numbers and print the result in third text box.

To display the output in third text box there are many ways. First way : Take input from HTML make calculation and display the output in text box, for this use <input type="text" value="output"/> inside PHP script. like:

<?php		
if(isset($_POST['add']))
{
$x=$_POST['fnum'];		
$y=$_POST['snum'];				
$sum=$x+$y;		 
echo "Result:<input type='text' value='$sum'/>";			
}
?>
	
<body>
<form method="post">
Enter first number <input type="text" name="fnum"/><hr/>
Enter second number <input type="text" name="snum"/><hr/>	   		   
<input type="submit"  name="add" value="ADD"/>
</form>
</body>
Output
Result:
Enter first number
Enter second number

In the given example,

First we design two textbox using HTML script with attribute name with ( value="Fnum" for first textbox) and (value= "Snum" for second textbox). A submit button with (name=Add).

When we run the program the logic that is defined inside PHP script, $_POST[ ] is used to collect the values from a form. it store the value in variables ($x,$y).

But we want to show the sum inside the textbox. for this we define textbox inside the "echo" statement with (value="$sum").

WAP Sum of two number and display the Result in third text box

<?php	
$x=$_POST['fnum'];
$y=$_POST['snum'];
$sum=$x+$y;
?>
 
<body>
<form method="post">
Result  <input type="text" value="<?php echo @$sum;?>"/><hr/>
Enter first number <input type="text" name="fnum"/><hr/>
Enter second number <input type="text" name="snum"/><hr/>	   		   
<input type="submit" value="ADD"/>
</form>
</body>
Output
Result:
Enter first number
Enter second number

In previous example,

the textbox is defined inside the PHP script. Instead this We define third textbox outside the PHP script.

Value attribute of <Input> tag is used to show the output inside the textbox here we define a PHP script inside the value Property of the textbox.

  We create form using HTML script with (method="post") and action="output.php". We define Five fields inside the HTML form.

First for name,Second for Email_id, Third for Password,Fourth for Mobile No,and Fifth for address. A button is used to display data on next page after click on this button.

inside the (output.php) page we create same form format. But value attribute of every <input> type tag is used to declare the PHP script inside the value with $_POST[ ] .

$_POST[ ] is define with name of a field like. $_POST['name'], $_POST['email']. As we run this program the dada that is Entered in First page will dispaly as it is data on Second(output.php) page.
