problems displaying json data retrieved using php curl - php

Question

First, thanks for you reading. Here is my code
what my json data looks like when viewed in a browser using the url,
{
"$totalResults": 1500,
"$startIndex": 1,
"$itemsPerPage": 3,
"$resources": [
{
"$uuid": "5e7b9312-52e5-4fe1-b3e4-633ca04c9764",
"$httpStatus": "OK",
"$descriptor": "",
"name": "Heinz Tomato Sauce Sachets Qty 200"
},
{
"$uuid": "1a0f9dca-c417-4cff-94d2-99d16438723f",
"$httpStatus": "OK",
"$descriptor": "",
"name": "Heinz Brown Sauce Sachet Qty 200"
},
{
"$uuid": "126fdb17-81ce-41b4-bdba-91d0a170262a",
"$httpStatus": "OK",
"$descriptor": "",
"name": "Heinz English Mustard Sachets Qty 300"
}
]
}
test2.php
<?php
// SAGE URL
$url = 'http://localhost:5493/sdata/accounts50/GCRM/-/commodities?select=name&count=3&format=json';
//SAGE USERNAME & PASSWORD
$username = 'test';
$password = 'test';
//initiaize
$ch = curl_init();
//set options
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_USERPWD, $username . ":" . $password);
curl_setopt($ch, CURLOPT_HTTPGET, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, 0);
//execute
$result = curl_exec($ch);
//close curl session / free resources
curl_close($ch);
$json = json_decode($result);
foreach ($json->{'$resources'} as $mydata) {
echo $mydata->name;
};
?>
errors im getting
Notice: Trying to get property of non-object in C:\xampp\htdocs\Sage Json\test2.php on line 29
Warning: Invalid argument supplied for foreach() in C:\xampp\htdocs\Sage Json\test2.php on line 29
I’m not sure what's going wrong, this works if i get the same data from a file but not if I’m retrieving it from at rest server, and if anyone could shed some light I would be grateful

Answer 1

Ajking11 the reason your getting Invalid argument supplied for foreach() is that $json vairiable is overwritten and has no data try somthing like this
<?php
// SAGE URL
$url = 'http://localhost:5493/sdata/accounts50/GCRM/-/commodities?select=name&count=3';
//SAGE USERNAME & PASSWORD
$username = 'test';
$password = 'test';
//initiaize
$ch = curl_init();
//set options
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_USERPWD, $username . ":" . $password);
curl_setopt($ch, CURLOPT_HTTPGET, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, 0);
//execute
$result = curl_exec($ch);
//close curl session / free resources
curl_close($ch);
$xml = simplexml_load_string($result);
$data = json_encode($xml);
$arr = json_decode($data,TRUE);
foreach ($arr['entry'] as $k=>$v){
echo $v; // etc.
}
note that I have removed &format=json and encoded later hope this help let me know how your getting on

you might like to use this code and refine it to your needs
<?php
// SAGE URL
//$url = 'http://computer_2:5493/sdata/accounts50/GCRM/-/commodities?select=name&count=3&select=name&count=10&format=json';
$url ='http://localhost:5493/sdata/accounts50/GCRM/-/tradingAccounts?select=name&count=10';
//SAGE USERNAME & PASSWORD
$username = 'MANAGER';
$password = '';
//initiaize
$ch = curl_init();
//set options
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_USERPWD, $username . ":" . $password);
curl_setopt($ch, CURLOPT_HTTPGET, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, 0);
//execute
$result = curl_exec($ch);
//close curl session / free resources
curl_close($ch);
$xml = simplexml_load_string($result);
foreach($xml->xpath("//sdata:payload") as $entry) {
// xpath here must be from payload to tradingAccount
$content = $entry->xpath("./crm:tradingAccount");
foreach($content as $c) {
// Make set of children with prefix crm
$nodes = $c->children('crm', true);
echo $nodes->reference . " | " . $nodes->name . " / " . $nodes->openedDate . "<br />\n";
}
}
thanks PHPhil and splash58 for your assistance with the namespace issue

As Artful_dodger say's the json is the problem here is how I would solve it
<?php
// SAGE URL
$url = 'http://localhost:5493/sdata/accounts50/GCRM/-/commodities?select=name&count=3&format=json';
//SAGE USERNAME & PASSWORD
$username = 'MANAGER';
$password = '';
//initiaize
$ch = curl_init();
//set options
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_USERPWD, $username . ":" . $password);
curl_setopt($ch, CURLOPT_HTTPGET, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, 0);
//execute
$result = curl_exec($ch);
//close curl session / free resources
curl_close($ch);
// doing a substring as there are 3 weird characters being passed back from IIS in front of the string
$json = json_decode(substr($result, 3, strlen($result)), true);
foreach ($json['$resources'] as $mydata) {
echo $mydata['name'] . "<br>";
}

Answer 4

PHP json_decode function returns an array and not an object, so instead of using
foreach ($json->{'$resources'} as $mydata) {
echo $mydata->name;
};
you should use
foreach ($json['$resources'] as $mydata) {
echo $mydata['name'];
};
UPDATE
your test2.php should look like this:
<?php
// SAGE URL
$url = 'http://localhost:5493/sdata/accounts50/GCRM/-/commodities?select=name&count=3&format=json';
//SAGE USERNAME & PASSWORD
$username = 'test';
$password = 'test';
//initiaize
$ch = curl_init();
//set options
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_USERPWD, $username . ":" . $password);
curl_setopt($ch, CURLOPT_HTTPGET, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, 0);
//execute
$result = curl_exec($ch);
//close curl session / free resources
curl_close($ch);
$json = json_decode($result);
$json = (array)$json;
foreach ($json['$resources'] as $mydata) {
echo $mydata->name . "<br>";
};
in your code the major problem was in naming of the JSON attribute $resources: it is named as PHP variable and it causes the problem.
Converting the decoded variable into an array solves the problem as the associative array key is a string.

Answer 5

im really sorry for never getting back to you. so it turn out that when you get data from the sage service, it returned to you in "utf 8 bom".
So before i can display any thing i needed to remove the format by clearing the first three characters with in the array. with the substr() function.
$json_data = substr($json_data, 3);
Thank you all for helping with this problem.
