PHP Display Result In Textbox



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


1) Use text-box inside PHP script.
Eg i
   <?php
  $x=$_POST['fnum'];
  $y=$_POST['snum'];
  if(isset($_POST['add']))
  {
   $sum=$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="snum" 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”).

sum of two numbers and display the output in third text box

Eg ii
 
 <?php
 $x=$_POST['fnum'];
 $y=$_POST['snum'];
 $sum=$x+$y;
 if(isset($_POST['add']))
 ?>
 
 <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" name="snum" name="add" 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.

Create a Registration form fill all the information and display the result in text box on next page

Eg iii
 
Save the program as registration form.html
<html> <body> <form method="post" action="output.php"> <table bgcolor="#C4C4C4" align="center" width="380" border="0"> <tr> <td align="center"colspan="2"><font color="#0000FF" size="5">Registration Form</font></td> </tr> <tr> <td width="312"></td> <td width="172"> </td> </tr> <tr> <td><Enter Your Name </td> <td><input type="text" name="name" /></td> </tr> <tr> <td>Enter Your Email </td> <td><input type="email" name="email" /></td> </tr> <tr> <td>Enter Your Password </td> <td><input type="password" name="password" /></td> </tr> <tr> <td>Enter Your Mobile Number </td> <td><input type="number" name="num" /></td> </tr> <tr> <td>Enter Your Address </td> <td><textarea name="address"></textarea></td> </tr> <td align="center" colspan="2"><input type="submit" value="save" name="submit" /></td> </table> </form> </body> </html>
Registration Form
Enter Your Name
Enter Your Email
Enter Your Password
Enter Your Mobile Number
Enter Your Address

Output.php page

                  
Save the program as output.php
<table bgcolor="#C4C4C4" align="center" width="380" border="0"> <tr> <td align="center"colspan="2"><font color="#0000FF">Your Output</font></td> </tr> <tr> <td>Your Name is</td> <td><input type="text" value="<?php echo $_POST['name']; ?>" readonly="" /></td> </tr> <tr> <td>Your Email is</td> <td><input type="email" value="<?php echo $_POST['email']; ?>" readonly="" /></td> </tr> <tr> <td>Your Password is</td> <td><input type="password" value="<?php echo $_POST['password']; ?>" readonly="" /></td> </tr> <tr> <td>Your Mobile Number is</td> <td><input type="number" value="<?php echo $_POST['num']; ?>" readonly="" /></td> </tr> <tr> <td>Your Address is</td> <td><textarea readonly="readonly"><?php echo $_POST['address'];?></textarea></td> </tr> </table>
Output :
Your Output will display like
Your Name is
Your Email is
Your Password is
Your Mobile Number is
Your Address is
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 dipaly as it is data on Second(output.php) page.
