Question

I look for examples to solve my problem but im confused.
If Ii have a json array like this:

$json = '{"a":"test","b":"test2"},{"a":"test3","b":"test4"}';

//decode to get as php variable
$obj = json_decode($json);

My problem is when i try to insert the values in the database

mysql_query("INSERT INTO suspiciousactivity (ID,Notes)
VALUES ('".$obj->{'a'}."','".$obj->{'b'}."')")or die(mysql_error());

I get this error: duplicate entry for key PRIMARY

How can I insert a multiple values from my JsonArray to my database?

Answer 1

try to use:

$json = '{"a":"test","b":"test2"},{"a":"test3","b":"test4"}';

//decode to get as php variable
$arr = json_decode($json,true); //true to decode as a array not an object

mysql_query("INSERT INTO suspiciousactivity (ID,Notes)
VALUES ('".$arr[0]['a']."','".$arr[0]['b']."')")or die(mysql_error());
//use it as an array.
