POSTing Email in a form - Undefined index


Recommended Posts

I am designing a form where the users input information to be stored on a database.

All of the other inputs apart from the email post OK, but the email does not!

The error is: Notice: Undefined index: email in /home/hp3-linc4-nfs2-y/555/1099555/user/htdocs/includes/renew1.php on line 19

Consequently the mysqli query does not succeed.

Here is the section of code in the html file:

<h1>Online Renewal Form</h1>
<form action="includes/renew1.php" method="post">
    <fieldset>
    
    <p><label for= "firstname"><b>Enter Firstname:</b></label> 
    <input type="text" name="firstname" id="firstname" value="firstname" size="20" maxlength="20"/></p>
    <p><label for= "surname"> <b>Enter Surname: </b></label>

    <br />
    <div align="left"><input type="submit" name="submit" value="Submit" /></div>
    <input type="hidden" name="submitted" value="TRUE" />

</form>   

The code in the PHP file is as follows:

 $trimmed = array_map('trim', $_POST);
        
	 $Fname = mysqli_real_escape_string($dbc, $_POST['firstname']);
	 $Sname = mysqli_real_escape_string($dbc, $_POST['surname']);
	 $Road = mysqli_real_escape_string($dbc, $_POST['road']);
	 $Town = mysqli_real_escape_string($dbc, $_POST['town']);
	 $County = mysqli_real_escape_string($dbc, $_POST['county']);
	 $Pcode = mysqli_real_escape_string($dbc, $_POST['pcode']);
	 $Phone = mysqli_real_escape_string($dbc, $_POST['phone']);
	 $Mobile = mysqli_real_escape_string($dbc, $_POST['mobile']);
	 $Email = mysqli_real_escape_string($dbc, $_POST['email']);
	 $DOB = mysqli_real_escape_string($dbc, $_POST['dob']);
	 $BMFA = mysqli_real_escape_string($dbc, $_POST['bmfa_no']);
	 $C_mem = mysqli_real_escape_string($dbc, $_POST['country_mem']);
	 $Amount = mysqli_real_escape_string($dbc, $_POST['subs_amount']);
	 $meth = mysqli_real_escape_string($dbc, $_POST['pay_meth']);
	 $club = mysqli_real_escape_string($dbc, $_POST['club_mem']);
	 $training = mysqli_real_escape_string($dbc, $_POST['train']);

I thought that the problem was in the HTML file, but I am unable to see where it is incorrect.

Please help?

You could simplify the code a bit. If you enclose the input field with the <label> tag, the "id" and "for" attributes are unnecessary. For example:

<p><label><b>Enter Firstname:</b> 
<input type="text" name="firstname" value="firstname" size="20" maxlength="20"/></label></p>

More information about the <label> tag can be found here:
