unable to read checkbox and radio

[sudhakararaog]

 

i am using a self submitting form

 

<form action="<?php echo $_SERVER["PHP_SELF"]; ?>" method="POST" id="test2" name="test1">

 

i need to do a validation of textfields, checkboxes, radio buttons

 

i am able to read, display and validate textfields after the form has been submitted however i am getting an error for

 

checkbox and radio buttons.

 

code for textfields

 

username <input type="text" name="username"  value="<?php echo($username) ; ?>" />

 

$username = htmlentities($_POST["username"]);

 

if($username == "") { $error.=" enter username <br />"; }

 

for checkboxes and radio buttons i am getting

"Notice: Undefined index: checkboxname "    for checkbox

"Notice: Undefined index: radiobuttonname " for radio button

 

presently the code for checkbox and radio button is

 

<input type="checkbox" name="cbox" value="abc" />

 

$deposit = $_POST["cbox"];

 

 

<input type="radio" name="radioname" value="one"> one

<input type="radio" name="radioname" value="two"> two

 

$radioname = $_POST["radioname"];

 

i have tried cbox[] radioname[] however i keep getting

"Notice: Undefined index: cbox " and "Notice: Undefined index: radioname "

for checkbox and radio button

 

please advice.

 

thanks.

Try using isset()

 

$username = htmlentities($_POST["username"]);
if (!isset($username)) { $error = "enter username \n"; }

$deposit = $_POST["cbox"];
if (!isset($deposit)) { $error = "your error\n"; }

$radioname = $_POST["radioname"];
if (!isset($radioname)) { $error = "your other error\n"; }
