How to test returned json result? - php

Question

I have an Ajax Request that is getting data from my database, specifically two columns from it, company_id and people_id,
I need to test the result that comes from the json result, I need to check if a specific people_id exists in the result,
Here is my Ajax Request
Ext.Ajax.request({
url: 'system/index.php',
method: 'POST',
params: {
class: 'CompanyPeople',
method: 'secget',
data: Ext.encode({
people_id: Ext.getCmp('peopleGrid').selectedRecord.data.people_id
})
},
success: function (response) {
},
failure: function () {
}
});
I thought I could do this following code in the success function but it didnt work
if (data == 0) {
Ext.MessageBox.alert('Status', 'Person is not attached to anything bud!.');
}
else {
Ext.MessageBox.alert('Status', 'Person already attached to another company.');
}
Also here is my php
class CompanyPeople extends Connect {
function __construct() {
parent::__construct();
}
public function secget($vars) {
$sql = "SELECT * FROM CompanyPeople where people_id={$vars->data->people_id}";
$data = array();
$total = 0;
if ($result = $vars->db->query($sql)) {
while ($row = $result->fetch_assoc()) {
$data[] = array("people_id" => intval($row["people_id"]));
$total++;
}
$result->free();
}
echo json_encode(array("success" => true, "total" => $total, "topics" => $data));
}
}

Answer 1

I think something like this should work:
success: function( response ){
if(response.success === true) {
var personExist = false;
for(var i = 0; i < response.topics.lenght; ++i) {
// Your specific people_id in myValue
if(response.topics[i]['people_id'] === myValue) {
personExist = true;
break;
}
}
}
},
