i have a form with checkboxes and i was wondering how i could write the php code so that the choices you check can come into my email. here is the html coding for the form:

<form action="<?php echo $me;?>" method="post" name="form1" id="form1">
<p>Name :
<input type="text" name="textfield">
</p>
<p>Course:
<input type="text" name="textfield">
</p>
<p>Tel No:
<input type="text" name="textfield">
</p>
<p>
<input type="checkbox" name="checkbox" value="Judicial Committee">
Judicial Committee<br>
<input type="checkbox" name="checkbox" value="Welfare Committee">
Welfare Committee<br>
<input type="checkbox" name="checkbox" value="External Affairs Committee">
External Affairs Committee<br>
<input type="checkbox" name="checkbox" value="Transport Committee">
Transport Committee<br>
<input type="checkbox" name="checkbox" value="Disciplinary Committee">
Disciplinary Committee<br>
<input type="checkbox" name="checkbox" value="Entertainment Committee">
Entertainment Committee<br>
<input type="checkbox" name="checkbox" value="Publication Committee">
Publication and Information </p>
<p align="center">
<input type="submit" name="Submit" value="Join Now">
</p>
<p align="left"> <br>
</p>
</form>

You should change the checkbox names, they are all the same now (each checkbox name has to be unique). PHP code to identify whether a checkbox is checked, use:
[php]if(isset($_POST['checkbox_name'])) echo 'checked';[/php]

<input name="cd0" type="checkbox" checked="checked">
<?
if(isset($_POST['cd0'])){ echo 'checked';}
?>

dont works, can u help me?

You need to post the form.


myform.php
[PHP]
<form action="check.php" method="POST" name="myform">
<input name="cd0" type="checkbox" checked="checked">
</form>[/PHP]

check.php
[PHP]
<?PHP
if(isset($_POST['cd0'])){ echo 'checked';}
?>
[/PHP]
