PHP MySQL Insert array - php

Question

I'm having trouble with inserting the values from this array. Here example:
$arr = json_decode($_POST['dynfields'], true);
//{"dynfields":{"dynfields[0][DescRepair]":"Desc repair","dynfields[0][NestParts]":"Parts","dynfields[0][EdPrice]":"10","dynfields[0][DateRepair]":"2015-07-20","dynfields[1][DescRepair]":"Desc repair","dynfields[1][NestParts]":"Parts","dynfields[1][EdPrice]":"5","dynfields[1][DateRepair]":"2015-07-20"}}
foreach ($arr as $key => $fieldArray ) {
foreach($fieldArray as $k => $v) {
echo $k . " - " . $v . "<br>"; // result: dynfields[0][DescRepair] - Desc repair
dynfields[0] [NestParts] - Parts
dynfields[0][EdPrice] - 10
dynfields[0][DateRepair] - 2015-07-20
dynfields[1][DescRepair] - Desc repair
dynfields[1][NestParts] - Parts
dynfields[1][EdPrice] - 5
dynfields[1][DateRepair] - 2015-07-20
}
//$query = mysqli_query($mysqli, "INSERT INTO repair (DescRepair, NestParts, EdPrice, DateRepair) VALUES ('?', '?', '?', '?')") or die(mysqli_error($mysqli));
}
This is my code, but I don't know how to insert the value in db. Can you give me any suggestions. Thanks.

Answer 1

I did not understand very well your code, but at first your json is bad, on post, this is an example of right json:
{
"dynfields": [
{
"DescRepair": "Desc repair",
"NestParts": "Parts",
"EdPrice": "10",
"DateRepair": "2015-07-20"
},
{
"DescRepair": "Desc repair",
"NestParts": "Parts",
"EdPrice": "5",
"DateRepair": "2015-07-20"
}
]
}
Then you can make a foreach with the dynfields data:
$myvar = json_decode($json,true);
$data = $myvar['dynfields'];
foreach(array_keys($data) as $index){
var_dump($data[$index]);
}
then you will get something like this (var_dump):
array (size=4)
'DescRepair' => string 'Desc repair' (length=11)
'NestParts' => string 'Parts' (length=5)
'EdPrice' => string '10' (length=2)
'DateRepair' => string '2015-07-20' (length=10)
array (size=4)
'DescRepair' => string 'Desc repair' (length=11)
'NestParts' => string 'Parts' (length=5)
'EdPrice' => string '5' (length=1)
'DateRepair' => string '2015-07-20' (length=10)

Answer 2

$query = mysqli_query($mysqli, "INSERT INTO repair (DescRepair, NestParts, EdPrice, DateRepair) VALUES ('?', '?', '?', '?')") or die(mysqli_error($mysqli))
relace each ? with {$arr['xxxxx']} Where xxxxx are your array keys
make sure to well-escape the variables to prevent SQL Injection
Hint: you can use PDO or prepared statements
