what I am trying to do is to create a from, and execute a php script after the submit has been pressed. the problem seems to be that the page of wprdpress with the form and the code gets executed all at once.
If I put the code below into a regular test.php file on my server, it does what it is supposed to do (echo "Form Submitted!") after I click submit. However if I put the same code in a page template or a wp page it spits it out all at once (the form, and the "form submitted).
<html>
<head>
<title>Notify on Submit</title>
</head>
<body>
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="POST">
<label>Name: <input type="text" name="name" /></label>
<input type="submit" value="Submit" />
</form>
<?php if (count($_POST)>0) echo "Form Submitted!"; ?>
</body>
</html>
I have no idea why this is like that, and would really need some help on this.
What I have also done is to create two different wp pages(one goes to the other). It works, but will create a bit of a mess. I would like to do this in one page.
page 1
<form action="page2" method="POST">
Your form input.
<input type="submit" name="submit" />
</form>
Page 2
<?php
if (count($_POST)>0)
{
echo "Form Submitted!";
unset($_POST);
$_POST = array();
}
else echo "Form has been reset!";
?>
Probably there is another form on the Wordpress page using the POST method. Instead of checking for $_POST > 0 (which will only tell you that something was posted) add some identifier to your form, and check for that so you can tell if your form was posted.
A simple way to do this is with a hidden input:
