Very Basic SQL Making Page Bomb - php

Question

So I'm training in MVC and extending functionality from a tutorial. I'm not getting any echos after "SUBMITTED: " with each of the values for binding. I double-checked and ran the query in PHPMyAdmin and it's inserting fine. The page is just bombing as soon as I call $this->query and I don't understand why. In the add function that's bombing, I'm trying to add a List Item. List Items (like Vacuum) belong to a List (like Cleaning). The class where I add Lists is EXACTLY the same and works perfectly.
public function add(){
// Sanitize POST
$post = filter_input_array(INPUT_POST, FILTER_SANITIZE_STRING);
// show the List name
$lModel = new ListModel();
$lName = $lModel->getListTitle($this->listID);
if($post['submit']){
echo "SUBMITTED: Name: " . $post['name'] . " ID: " . $this->listID . " And 1 for Position<br>";
// Insert
$this->query("INSERT into list_item (list_id, name, position) VALUES (:list_id, :name, :position)");
echo "After query<br>";
$this->bind(':list_id', $this->listID);
$this->bind(':name', $post['name']);
$this->bind(':position', 1);
echo "After binding<br>";
//Verify
$this->execute();
echo "Execute?<br>";
if($this->lastInsertId()){
echo "Insert ID " . $this->lastInsertId();
//redirect
//header("Location: " .ROOT_URL."listItems/index/" . $this->listID);
}else{
echo "Didn't insert<br>";
Messages::setMsg('Failed to insert list','error');
}
}
//echo "lName: $lName";
return $lName;
}
}
Here is the entire class for your viewing pleasure.
<?php
class ListItemModel extends Model{
public $listID;
public function __construct($id){
$this->listID = $id;
}
public function Index(){
return "some data";
$this->query("SELECT * FROM list_item WHERE list_id = :list_id ORDER BY create_dt DESC");
$this->bind(':list_id', $this->listID);
$rows = $this->resultSet();
return $rows;
}
public function add(){
// Sanitize POST
$post = filter_input_array(INPUT_POST, FILTER_SANITIZE_STRING);
// show the List name
$lModel = new ListModel();
$lName = $lModel->getListTitle($this->listID);
if($post['submit']){
echo "SUBMITTED: Name: " . $post['name'] . " ID: " . $this->listID . " And 1 for Position<br>";
// Insert
$this->query("INSERT into list_item (list_id, name, position) VALUES (:list_id, :name, :position)");
echo "After query<br>";
$this->bind(':list_id', $this->listID);
$this->bind(':name', $post['name']);
$this->bind(':position', 1);
echo "After binding<br>";
//Verify
$this->execute();
echo "Execute?<br>";
if($this->lastInsertId()){
echo "Insert ID " . $this->lastInsertId();
//redirect
//header("Location: " .ROOT_URL."listItems/index/" . $this->listID);
}else{
echo "Didn't insert<br>";
Messages::setMsg('Failed to insert list','error');
}
}
//echo "lName: $lName";
return $lName;
}
}
?>
And here's the query function in Model as requested
public function query($query){
$this->stmt = $this->dbh->prepare($query);
}

Answer 1

I figured it out!!!
Because I was using the constructor in ListItemModel (which extends Model) to pass in the $id for the list, I needed parent::__construct().
Thanks, everyone!
