Php admin Blog Post error


Recommended Posts

Hello! I am a 17 year old beginner Php student and I am currently creating a page for which I would like to create a blog management admin interface. I went very well, I can already add the categories to the database, through the admin interface or I can list them on the website. However, there would be a problem with creating a Blog post. Because I use the same create () function as for adding a category, but unfortunately the Blog Post does not add to the database. I don't get any php error code just when I try to list the post id after the create function. Instead of a value of 1, I get a 0. I enclose the code of the blog post and its control, as well as the data of my database!

Blogpost controll code (posztok.php)

 

----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

 

 

 

<?php
include("blogigazolas.php"); ?>


<?php
$table = 'blogposts';


$kategoriak = selectAll('blog_kategoriak');
$posts = selectAll('blogposts');


$errors = array();

if (isset($_POST['add-post'])) {
unset($_POST['add-post'], $_POST['kategoria_id']);
$_POST['user_id'] = 1;
$_POST['published'] = 1;

$postid = create($table, $_POST);
dd($postid);

}


?>

----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

I see everything okay in these codes, because I add the category to the database in the same way when adding a category my function called dd is at the end of the line of code, it's just for checking, it shows results.

my create() function seen like this:

 

function create($table, $data)
{
global $conn;
$sql = "INSERT INTO $table SET ";


$i = 0;
foreach ($data as $key => $value) {
if ($i === 0) {
$sql = $sql . " $key=?";
} else {
$sql = $sql . ", $key=?";
}
$i++;

}

$stmt = executeQuery($sql, $data);
$id = $stmt->insert_id;
return $id;
}

 

----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The strange thing is that if I add 1-2 items to the database statically without php code, it is detected and displayed in the blog editing menu, but I can't add a post to the database via the admin interface itself, that's why I wrote here ! :) From testing, I also print the end result of the create function at the end of the control code, which should return an id, but instead of id 1 I get a value of 0 and the post doesn't added to the database after pressing the post button['add-post'] and unfortunately I can't figure out why it is ?! I also attach the pictures of the problem!
