CRUD PDO working on XAMPP but not on live server - php

Question

I am trying to update and add posts to a custom coded blog using PDO.
I can read and delete fine, but adding posts or editing them does not work on the live server.
It works fine on XAMPP...
I have made sure the PDO_mysql extension is enable on my database.
At a loss as to where the problem is?
My EDIT POST code looks like:
<?php
//if form has been submitted process it
if(isset($_POST['submit'])){
//collect form data
extract($_POST);
//very basic validation
if($postID ==''){
$error[] = 'This post is missing a valid id!.';
}
if($postTitle ==''){
$error[] = 'Please enter the title.';
}
if($postDesc ==''){
$error[] = 'Please enter the description.';
}
if($postCont ==''){
$error[] = 'Please enter the content.';
}
if(!isset($error)){
try {
$postSlug = slug($postTitle);
//insert into database
$stmt = $db->prepare('UPDATE blog_posts_seo SET postTitle = :postTitle, postSlug = :postSlug, postDesc = :postDesc, postCont = :postCont WHERE postID = :postID') ;
$stmt->execute(array(
':postTitle' => $postTitle,
':postSlug' => $postSlug,
':postDesc' => $postDesc,
':postCont' => $postCont,
':postID' => $postID
));
//delete all items with the current postID
$stmt = $db->prepare('DELETE FROM blog_post_cats WHERE postID = :postID');
$stmt->execute(array(':postID' => $postID));
if(is_array($catID)){
foreach($_POST['catID'] as $catID){
$stmt = $db->prepare('INSERT INTO blog_post_cats (postID,catID)VALUES(:postID,:catID)');
$stmt->execute(array(
':postID' => $postID,
':catID' => $catID
));
}
}
//redirect to index page
header('Location: index.php?action=updated');
exit;
} catch(PDOException $e) {
echo $e->getMessage();
}
}
}
?>
<?php
//check for any errors
if(isset($error)){
foreach($error as $error){
echo $error.'<br />';
}
}
try {
$stmt = $db->prepare('SELECT postID, postTitle, postDesc, postCont FROM blog_posts_seo WHERE postID = :postID') ;
$stmt->execute(array(':postID' => $_GET['id']));
$row = $stmt->fetch();
} catch(PDOException $e) {
echo $e->getMessage();
}
?>
and my ADD POST code is
<?php
//if form has been submitted process it
if(isset($_POST['submit'])){
//collect form data
extract($_POST);
//very basic validation
if($postTitle ==''){
$error[] = 'Please enter the title.';
}
if($postDesc ==''){
$error[] = 'Please enter the description.';
}
if($postCont ==''){
$error[] = 'Please enter the content.';
}
if(!isset($error)){
try {
$postSlug = slug($postTitle);
//insert into database
$stmt = $db->prepare('INSERT INTO blog_posts_seo (postTitle,postSlug,postDesc,postCont,postDate) VALUES (:postTitle, :postSlug, :postDesc, :postCont, :postDate)') ;
$stmt->execute(array(
':postTitle' => $postTitle,
':postSlug' => $postSlug,
':postDesc' => $postDesc,
':postCont' => $postCont,
':postDate' => date('Y-m-d H:i:s')
));
$postID = $db->lastInsertId();
//redirect to index page
header('Location: index.php?action=added');
exit;
} catch(PDOException $e) {
echo $e->getMessage();
}
}
}
//check for any errors
if(isset($error)){
foreach($error as $error){
echo '<p class="error">'.$error.'</p>';
}
}
?>
Is there anything I should check on the MySQL DB or is there something in my code that is preventing my CRUD from working in a live environment?
As said before, the exact same code (other than the config file) is working on XAMPP.

Answer 1

It might be a privilege error on the server side, since you cannot edit (write) the files or create new ones. I suggest checking the users privileges on the database.
When you say it does not work, what does it return to you?
Have you tried a var_dump or echo if it works as a query, or it doesn't allow the query to execute at all?
UPDATE:
Last but not least, the configuration file, as suggested by the comments, should be the main problem. It really depends how you have configured the files to work on the server. Check includes and such.

Answer 2

The problem is how you insert DATE.
That's the only difference between Insert, update and delete.
The best is not to add it at all via PHP and since you are adding the current time you can let the database do it for you.
':postDate' => date('Y-m-d H:i:s') <- let the db do it for you as default parameter set to now() or just use TIMESTAMP probably the best.
