AJAX and JSON with PDO MySQL - php

Question

I'm trying to get data from an attribute, pass it through ajax into another page, and then insert into mysql.
Right now I have some div elements
<div data-categories="[{"name":"Gastropub","pluralName":"Gastropubs"},{"name":"Food","pluralName":"Food"}]">
Name
</div>
Breaking it down:
-----------------------
[
{"name":"Gastropub","pluralName":"Gastropubs"},
{"name":"Food","pluralName":"Food"},
{"name":"more","pluralName":"more"}
]
------------------------
data-categories is where I insert a json_encoded array and it pops that out. When I'm trying to do is figure out the best practice of using ajax to get that value maybe with
var cats = $('div').data('categories');
$.ajax(function(){
type:"POST",
url:"other.php",
data: "data="+cats,
success:function(data){
alert("success");
}
});
other.php
Now I'm trying to figure out how to save each value separately into my MySQL in this other.php, if I have a table with columns : name and pluralName (and maybe add more later on) in MySQL data
if(isset($_POST['data'])){
$insert = $dbh->prepare("INSERT INTO cats(name,pluralName) VALUES(?,?)");
}
How do I get those values from a set of json values and insert each value into the proper column? As you can see from the example above, I have more than 1 name and pluralName

Answer 1

Making an AJAX call would be like :
var data = $("div").attr("data-categories");
$.ajax({
type: "POST",
url: "other.php",
data: "data="+data,
function(data){
alert("success");
}
});
If you are getting the data in $_POST array then you can probably use :
<?php
$str = $_POST['data'];
$data = json_decode($str, true);
//print_r($data);
for($i=0;$i<count($data);$i++) {
$insert = "INSERT INTO cats(name,pluralName) VALUES('".$data[$i]['name']."','"+$data[$i]['pluralName']+"')";
//Insert in database
}

Try This:
Jquery
var dataStr = $("div").attr("data-categories");
$.ajax({
type: "POST",
url: "other.php",
data: {data:dataStr},
success:function(data){
alert("success");
}
});
PHP Code
<?php
if(isset($_POST['data']))
{
$data = $_POST['data'];
$jsonArray= json_decode($data, true);
for($i=0;$i<count($jsonArray);$i++) {
$insert = $dbh->prepare("INSERT INTO cats(name,pluralName) VALUES('".$jsonArray[$i]['name']."','"+$jsonArray[$i]['pluralName']+"')");
}
}
?>
