in array, json data and put in MySql with php - arrays

Question

I have a data under format 'JSON' like this one :
{
"email": "john#john.fr",
"line_items": [
{
"sku": "123456789",
"price": "0.67",
"price_with_tax": "4.00",
"tax_lines": [
{
"title": "tax010",
"rate": 0.01,
"price": "1.11"
},
{
"title": "tax00200",
"rate": 0.02,
"price": "2.22"
}
]
},
{
"sku": "012345666",
"price": "1.67",
"price_with_tax": "5.00",
"tax_lines": [
{
"title": "tax0003000",
"rate": 0.03,
"price": "3.33"
}
]
}
]
}
I want put it in my database (MySql) by PDO::prepare. My following sql query works but second line_items have not good value im Mysql :
1st item :::: good value
email:john#john.fr
sku:123456789
price:0.67
price_with_tax:4.00
price_tax1:1.11
price_tax2:2.22
2nd item ::::
email:john#john.fr
sku:012345666
price:1.67
price_with_tax:5.00
wrong value ::::
price_tax1:1.11
price_tax2:2.22
How can I put it good value ?
here is my code :
$dataDecode = json_decode($jsondata);
$email = $dataDecode->email;
try
{
$dtbs = new PDO($dsn_dev, $pdo_user, $pdo_password, array(PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION));
}
catch (Exception $e)
{
die('Error : ' . $e->getMessage());
}
try
{
foreach ($dataDecode->line_items as $obj)
{
$var_sku = $obj->sku;
$var_price = $obj->price;
$var_price_with_tax = $obj->price_with_tax;
$taxNewArray = array();
foreach ($dataDecode->line_items[0]->tax_lines as $obj2)
{
array_push($taxNewArray , $obj2);
}
$val1st = array_shift($taxNewArray);
$val2nd = array_pop ($taxNewArray);
$var_tax1 = $val1st->price;
$var_tax2 = $val2nd->price;
$stmt = $dtbs->prepare("INSERT INTO $tabledata ($mysql_email, $mysql_sku, $mysq_price, $mysql_price_with_tax, $mysql_price__tax1___line_items, $mysql_price__tax2___line_items)
VALUES (:email, :sku, :price, :price_with_tax, :price_tax1, :price_tax2)");
$stmt->execute(array(':email'=>$email,
':sku'=>$var_sku,
':price'=>$var_price,
':price_with_tax'=>$var_price_with_tax,
':price_tax1'=>$var_tax1,
':price_tax2'=>$var_tax2
));
}
}
catch(Exception $e)
{
throw $e;
}
Do you have a idée ?

Answer 1

If there's only one entry in tax_lines, your code will try to set $var_tax2 from the nonexistent second entry. You need to check for this and substitute some other value:
$var_tax2 = $val2nd ? $val2nd->price : '0.0';
The other problem is this line:
foreach ($dataDecode->line_items[0]->tax_lines as $obj2)
You're using the tax lines from the first line item every time. That should be:
foreach ($obj->tax_lines as $obj2)
