PHP: Having a problem with get_post
I am having a problem with the get_post method. Here is my code:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>Upload2</title>
<link href="style.css" rel="stylesheet" type="text/css">
</head>
<body>
<h1> Welcome to my search Engine </h1>
<?php
# SETUP
$thisFile = 'v4.php';
# INPUT FIELDS
echo <<< END
<form action="$thisFile" method="post">
<pre>
Search <input type="text" name="searchTerm"/>
<input type="submit" value="Add Record"/>
</pre>
</form>
END;
# EXTRACT INPUTTED FIELDSA
if(isset($_POST['searchTerm'])) {
# INITIALIZE INPUTTED VARIABLES
$mySearchTerm = get_post('searchTerm'); # <- PROBLEM LINE!
echo "You searched for: $mySearchTerm";
}
?>
</body>
</html>
The code works well before a search term is entered. The html looks as expected and this page is displayed in a browser:
After I enter a search term the pages looks the same BUT after going View -> Page Source I noticed something int开发者_如何学Pythoneresting. The end of the page looks like this:
Search <input type="text" name="searchTerm"/>
<input type="submit" value="Add Record"/>
</pre>
</form>
NOTE: There is no ending </body></html>
Turns out that get_post is not a PHP method. My textbook defined it on the next page as:
function get_post($var){
return mysql_real_escape_string($_POST[$var]);
}
I agree with sixtyfootersdude. The only thing missing is the database connection.
function get_post($conn, $var){
return $conn->real_escape_string($_POST[$var]);
}
Surely you can change:
$mySearchTerm = get_post('searchTerm'); # <- PROBLEM LINE!
To:
$mySearchTerm = $_POST['searchTerm'];
There is no get_post() function in PHP perhaps you are calling an undefined function.
Add the following at the top of your PHP block
ini_set('error_reporting', E_ALL);
ini_set('display_errors', true);
to see what it is going on.
You MISSED include or require for your get_post function and parser will push error with disabled error reporting.
And at the top of script add:
error_reporting(E_ALL);
require_once('this_file_where_you_have_get_post.php');
