I'm trying to create a custom blog system for a website I am working on, I have created all of the systems however when I try to insert the form to the database, the script executes however the data is not saved to the database. Some of the fields do contain large amounts of text and formatting using TinyMCE could this be the problem? When I test it with smaller amounts of text it works fine.
PHP script:
$conn = connect();
$action = $_GET['a'];
$id = $_GET['id'];
switch($action) {
case 'delete':
$sql = "DELETE FROM articles WHERE id='$id'";
if(mysql_query($sql)) {
echo "<script type='text/javascript'> alert('Article Deleted'); </script>";
header("Location: manage.php");
}
break;
case 'add':
if(isset($_POST['submit'])) {
$slug = $_POST['slug'];
$datecreated = $_POST['datecreated'];
$datepublish = $_POST['datepublish'];
$author = $_POST['author'];
$status = $_POST['status'];
$title = $_POST['title'];
$miniexcerpt = $_POST['miniexcerpt'];
$teaser = $_POST['teaser'];
$body = $_POST['body'];
$sql = "INSERT INTO articles (slug,datecreated,datepublish,author,status,title,miniexcerpt,teaser,body) values ('$slug','$datecreated','$datepublish','$author','$status','$title','$miniexcerpt','$teaser','$body')";
if(mysql_query($sql)) {
echo "<script type='text/javascript'> alert('Article Added'); </script>";
header("Location: manage.php");
}
}
break;
case 'edit':
if(isset($_POST['submit'])) {
$slug = $_POST['slug'];
$datecreated = $_POST['datecreated'];
$datepublish = $_POST['datepublish'];
$author = $_POST['author'];
$status = $_POST['status'];
$title = $_POST['title'];
$miniexcerpt = $_POST['miniexcerpt'];
$teaser = $_POST['teaser'];
$body = $_POST['body'];
$sql = "UPDATE articles SET slug='$slug',datecreated='$datecreated',datepublish='$datepublish',author='$author',status='$status',title='$title',miniexcerpt='$miniexcerpt',teaser='$teaser',body='$body' WHERE id='$id'";
if(mysql_query($sql)) {
echo "<script type='text/javascript'> alert('Article Updated'); </script>";
header("Location: manage.php");
}
}
break;
}
$conn = connect();
$action = $_GET['a'];
$id = $_GET['id'];
switch($action) {
case 'publish':
$sql = "UPDATE articles SET status='published' WHERE id='$id'";
if(mysql_query($sql)) {
echo "<script type='text/javascript'> alert('Article Published'); </script>";
header("Location: manage.php");
}
break;
}

Answer 1

Check your php.ini. Some parameters affect POST payload size.
post_max_size integer
Sets max size of post data allowed. This setting also affects file upload. To upload large files, this value must be larger than upload_max_filesize. Generally speaking, memory_limit should be larger than post_max_size. When an integer is used, the value is measured in bytes. Shorthand notation, as described in this FAQ, may also be used. If the size of post data is greater than post_max_size, the $_POST and $_FILES superglobals are empty. This can be tracked in various ways, e.g. by passing the $_GET variable to the script processing the data, i.e. , and then checking if $_GET['processed'] is set.
