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>
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>
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.
