I am rattling my brain here. I had added a code into my script to get rid of double posts, it has a timer which stops people double posting within 10 seconds.   Though since inserting the code you have an error where you will have to double post the same post because instead of inserting the post content into the database the submit button comes back with a blank result.   Why is this happening? (blank result instead of saying "post successfully posted etc." or "post not posted" it just comes up blank with no entry going into the database. This results in you having to re type your comment and re submit it hoping second time lucky)   This is my code once the submit has been hit.    

here is the basic script . i use this script for  edit html or text file.
<?php 

$action=$_POST['action']; 
$textarea=$_POST['textarea']; 

if($_GET['p']){

} 

// where to go back to after the edit ...

the script show error message after clicking the save button. the error message is
Warning: Cannot modify header information - headers already sent by (output started at c:\wamp\www\edit.php:6) in c:\wamp\www\edit.php on line 78

can any one help regarding this issue?

Previously, the PHP codebase I was using was that written by others, and I used their code to tinker with so I could get an understanding how PHP works.
Now that I am comfortable using PHP, I have written my own short PHP script from scratch with the aim of it seeing my newsletter system functioning at minimal, for the first time.
The newsletters system is made with HTML/PHP/MySQL.

I am having a problem with the PHP side of things where I am getting an error:
Quote

PHP Parse error: syntax error, unexpected T_IF on line 50

... which is:
Code: [Select]
if $_POST['action'] == 'Register' {
I am hoping someone that knows allot about PHP could take a look at my code and see whats wrong with it?

PHP code within confirm.html:
Code: [Select]
<?php
$link = mysql_connect('localhost', 'testusr', 'testpw');
mysql_select_db('testdb', $link);
$email = $_POST['e-mail'];
$query = 
if $_POST['action'] == 'Register' {
if $_POST['newsletter'] == 'Mens' {
"INSERT INTO newsletters(mens) VALUES('$email')";
}
elseif $_POST['newsletter'] == 'Mens & Womens' {
"INSERT INTO newsletters(mensandwomens) VALUES('$email')";
}
elseif $_POST['newsletter'] == 'Womens' {
"INSERT INTO newsletters(womens) VALUES('$email')";
}
;}
mysql_query ($link, $query);
mysql_close($link);
?>
HTML FORM code within index.html:
Code: [Select]
<FORM action="confirm.html" method="post">
<DIV>
<SPAN class="input">
Action:
<SELECT name="action">
<OPTION>Register</OPTION>
<OPTION>Unregister</OPTION>
</SELECT>&nbsp&nbsp&nbsp
E-mail: <INPUT name="e-mail" type="text"></INPUT>&nbsp&nbsp&nbsp
Newsletter:
<SELECT name="newsletter">
<OPTION>Mens</OPTION>
<OPTION>Mens & Womans</OPTION>
<OPTION>Womens</OPTION>
</SELECT>&nbsp&nbsp&nbsp
<INPUT class="submit" type="submit" value="Submit">
</SPAN>
</DIV>
</FORM>

I'm having trouble with my script. I'm getting pictures from the database and showing it in 3 columns and putting some information in each table location with the picture. But I made  a change and  now the table still works but I get a full blank page and have to scroll down to see the pictures.  Can anybody see where my problem exists, it was working fine but now it doesn't. Any help would be appreciated. Thanks in advance.

So, I'm trying to make a script that will send emails from apparently anyone.
Code: [Select]
<?php
$email = $_REQUEST['email']
$target = $_REQUEST['target']
$message = $_REQUEST['message']
$subject = $_REQUEST['subject']

mail( $target, $subject, $message, "From: $email" );
echo "Mail sent." ;
?>

Here's the HTML, if it matters.
Code: [Select]
<html>
<head>
<title>EMAIL SPOOFER</title>
</head>
<body>
<p>This program can make emails appear as if they came from any email address, real or fake!</p>
<form method="post" action="mailspoof.php">
Apparent sender: <input name="email" type="text" /><br />
Subject: <input name="subject" type="text" /><br />
Recipient: <input name="target" type="text" /><br />
Message:<br />
<textarea name="message" rows="15" cols="40">
</textarea><br />
<input type="submit" />
</form>

</body>
</html>

Here's the error I'm getting from my webhost:
Parse error: syntax error, unexpected T_VARIABLE in /home/a5938041/public_html/mailspoof.php on line 3

If I know me, it's probably the most stupid mistake in the universe, so please point it out. ::)
