I am retrieving data from a MySQL database using PHP and attempting to use JSON.stringify and JSON.parse to create an object. It works fine but I cannot get the assocaited keys/values. Just the entire object. I break this up in to parts. Here is the PHP code:
First PHP File:
<?php
session_start();
include("web_db_operations.php");
if(isset($_POST['recipeId']) && isset($_SESSION['email'])){
$recipeId = $_POST['recipeId'];
$email = $_SESSION['email'];
}
else{
echo "Did not work";
}
$results = getAllMyRecipesAsList_recipeTable2($email, $recipeId);
$_SESSION['recipeResults'] = $results;
header('location:web_selected_recipe.php');
exit();
?>
Second PHP File
function getAllMyRecipesAsList_recipeTable2(string $email, int $recipeId){
include 'config.php';
$sql = 'SELECT * FROM recipeTable WHERE email = :email AND recipeId = :recipeId';
$stmt = $conn->prepare($sql);
$stmt->bindParam(':email', $email, PDO::PARAM_STR);
$stmt->bindParam(':recipeId', $recipeId, PDO::PARAM_STR);
$stmt->execute();
$getResults = $stmt->fetchAll(PDO::FETCH_ASSOC);
$json = array();
if(count($getResults) > 0){
foreach($getResults as $row){
$json[] = array('firstName' => $row['firstName'],
'lastName' => $row['lastName'],
'email' => $row['email'],
'recipeName' => $row['recipeName'],
'description' => $row['description'],
'ingredients' => $row['ingredients'],
'prepTime' => $row['prepTime'],
'steps' => $row['steps'],
'nutrition' => $row['nutrition'],
'servings' => $row['servings'],
'rating' => $row['rating'],
'tags' => $row['tags'],
'imagePath' => $row['imagePath'],
'imageName' => $row['imageName'],
'recipeId' => $row['recipeId']
);
}
$results = json_encode($json);
return $results;
}else{
echo "no data found";
}
}
Then to retrieve in my JS file (this is just the relevant parts):
<script>
<?php $results = $_SESSION['recipeResults'];
var results = <?php echo $results; ?>;
var toString = JSON.stringify(results);
console.log(toString);
var parsed = JSON.parse(toString);
console.log(parsed);
</script>
Logging resultAsString yields this:
[{"firstName":"Marcus","lastName":"Holden","email":"marcus@gmail.com","recipeName":"Aloo Paratha","description":"","ingredients":"","prepTime":"25 Minutes","steps":"","nutrition":"","servings":"","rating":"","tags":"","imagePath":"../userRecipeImages","imageName":"9110164.jpg","recipeId":"1"}]
Logging parsed yields this:
[{…}]
0:description:
"No Description", email "marcus@gmail.com", firstName:"Marcus", imageName:"9110164.jpg", imagePath:"../userRecipeImages", ingredients:"Some Ingredients",lastName:"Holden", nutrition:"Not given", prepTime:"25 Minutes", rating:"5/10", recipeId:"1", recipeName:"Aloo Paratha", servings: "6", steps:"Your Steps Here", tags:"It's bread"
Now, I have tried all steps to get the value associated with a key... for instance my object here is called parsed... so I have tried parsed.firstName.. returns undefined... as well as Object.keys(parsed). I cannot seem to get the keys. I would like to work with it like an array... setting content like this:
element.innerHTML = parsed[2]... etc.
What am I missing here?
