JSON Decode to Multiple Tables - php

Question

I have been tasked with trying to map a json file to a database a sample of the json is given below:
configurationItems":[
{
"configurationItemVersion":"1.0",
"configurationItemCaptureTime":"2014-12-05T10:22:51.751Z",
"configurationStateId":1,
"relatedEvents":[ ],
"awsAccountId":"val",
"configurationItemStatus":"v",
"resourceId":"fg",
"ARN":"ggggg",
"awsRegion":"us-east-1",
"availabilityZone":"us-east-1b",
"configurationStateMd5Hash":"ggd45",
"resourceType":"AWS::EC2::Instance",
"resourceCreationTime":"2014-01-06T10:37:37.000Z",
"tags":{
"Name":"",
"cirrushq_id":""
},
using the following code I have been able to map the entries down to resource creation time but now wish to map the tags to a different table called tag
<?php
$con=mysqli_connect("localhost","root","","json_map");
$response = array();
$res=array();
$json = file_get_contents('C:\Users\Richard\Desktop\test.json');
if($json!=null){
$decoded=json_decode($json,true);
//$decode= var_dump($decoded);
//$ss=$decode["array"];
//echo $decoded['number'];
if(is_array($decoded["configurationItems"]))
{
foreach($decoded["configurationItems"] as $configurationItems)
//for($i=0;$i>sizeof($decoded["configurationItems"]);$i++)
{
$configurationItemVersion=$configurationItems["configurationItemVersion"];
echo "<br />","configuration_Item_Version:",$configurationItemVersion,"<br />";
$configurationItemCaptureTime=$configurationItems["configurationItemCaptureTime" ];
echo "configurationItemCaptureTime:",$configurationItemCaptureTime,"<br />";
$configurationStateId=$configurationItems["configurationStateId"];
echo "configurationStateId:",$configurationStateId,"<br />";
$awsAccountId=$configurationItems["awsAccountId"];
echo "awsAccountId:",$awsAccountId,"<br />";
$configurationItemStatus=$configurationItems["configurationItemStatus"];
echo "configurationItemStatus:",$configurationItemStatus,"<br />";
$resourceId=$configurationItems["resourceId"];
echo "resourceId:",$resourceId,"<br />";
$ARN=$configurationItems["ARN"];
echo "ARN:",$ARN,"<br />";
$awsRegion=$configurationItems["awsRegion"];
echo "awsRegion:",$awsRegion,"<br />";
etc etc
$result = mysqli_query($con, "INSERT INTO configuration_item(configuration_item_version,configuration_item_capture_time,configuration_state_id, aws_account_id, configuration_item_status, resource_id, arn, aws_region, availability_zone,configuration_state_md5_hash, resource_type, resource_creation_time)
VALUES('$configurationItemVersion','$configurationItemCaptureTime','$configurationStateId','$awsAccountId','$configurationItemStatus','$resourceId','$ARN','$awsRegion','$availabilityZone','$configurationStateMd5Hash','$resourceType','$resourceCreationTime' )")or die("Insert Failed ".((is_object($con)) ? mysqli_error($con) : (($___mysqli_res = mysqli_connect_error()) ? $___mysqli_res : false)));;
}// check if row inserted or not
if ($result) {
// successfully inserted into database
$response["code"] = 1;
$response["message"] = "successfully stored configuration items ";
// echoing JSON response
echo json_encode($response);
} else {
// failed to insert row
$response["code"] = 2;
$response["message"] = "Oops! An error occurred.";
// echoing JSON response
echo json_encode($response);
}
}
}
?>
I tried duplicating the code into a separate file and altering the insert statement to
if(is_array($decoded["configurationItems"]))
{
foreach($decoded["configurationItems"] as $configurationItems)
//for($i=0;$i>sizeof($decoded["configurationItems"]);$i++)
{
$Name=$configurationItems["Name"];
echo "<br />","Name:",$Name,"<br />";
$cirrushq_id=$configurationItems["cirrushq_id"];
echo "<br />","cirrushq_id:",$cirrushq_id,"<br />";
$result = mysqli_query($con, "INSERT INTO tag(name, cirrushq_id)
VALUES('$Name','$cirrushq_id' )")or die("Insert Failed ".((is_object($con)) ? mysqli_error($con) : (($___mysqli_res = mysqli_connect_error()) ? $___mysqli_res : false)));;
but to no avail it just returns unknown index Name

Answer 1

From what you wrote, I'm not completely sure to understand what's the cause of your problem.
However, let me point out a few inconsistencies I spotted:
1) Since you speak about tags (plural), I'm guessing you'd like to have more than one tag associated to each configurationItems element. In this case your JSON should be:
...
"tags":[{
"Name":"",
"cirrushq_id":""
},{
"Name":"",
"cirrushq_id":""
}]
...
2) According your JSON, to access tag name and tag cirrushq_id you should do:
$Name=$configurationItems["tags"]["Name"];
$cirrushq_id=$configurationItems["tags"]["cirrushq_id"];
and in the case you take into consideration my point 1), you'd have to make another loop through the tags:
foreach($decoded["configurationItems"] as $configurationItems)
{
...
foreach($decoded["configurationItems"]["tags"] as $tags)
{
$Name=$tags["Name"];
echo "<br />","Name:",$Name,"<br />";
$cirrushq_id=$tags["cirrushq_id"];
echo "<br />","cirrushq_id:",$cirrushq_id,"<br />";
// clearly, the INSERT query should also be inside this nested loop
}
}
3) From what you wrote in the tag INSERT query, you have a lowercase name column, while in your JSON, the index Name is uppercase...I know it's trivial but sometimes, when there's not another pair of eyes that can double-check your code, it's just simple stuff like this that make you waste a lot of time.
Hope to have been of help!
