Ik ben wat aan het spelen met PHP, maar ik krijg constant dezelfde foutmelding:

Fatal error: Function name must be a string in C:\xampp\htdocs\test\addtitle.php on line 16.

In phpMyAdmin heb ik al gecontroleerd of the veldtypes wel juist zijn. Via Google kwam ik een beschrijving van deze foutmelding tegen:

This error usually rears its ugly head when you are using variable functions. If you use a variable function and the variable you are using is unset, this error will result - I often get this when I am typing faster than I can think and I accidentally hit $ before a function name. PHP naturally interprets this is a variable-function call, and tries to look up the function name inside the variable.

Maar hier werd ik niet echt wijzer van.

PHP:

<html>
<head>
<title>Add New Booktitle</title>
</head>

<body>
<?php
if (isset($_POST['add']))
{
include 'library/config.php';
include 'library/opendb.php';

$title = $_POST['title'];

$query = "INSERT INTO title (title) VALUES ('$title')";
$mysql_query($query) or die('Error, insert query failed');

include 'library/closedb.php';
echo "New Booktitle added";
}
else
{
?>
<form method="POST">
<table width="400" border="0" cellspacing="1" cellpadding="2">
<tr>
<td width="100">Title</td>
<td><input name="title" type="text" id="title"></td>
</tr>

<tr>
<td width="100">&nbsp;</td>
<td><input name="add" type="submit" id="add" value="Add New Book Title"></td>
</tr>
</table>
</form>
<?php
}
?>
</body>
</html>
