My PHP is receiving data like this:
[
{
"EMAIL": "hello@example.com",
"GENDER": "Male"
},
{
"EMAIL": "info@example.com",
"GENDER": "Male"
}
]
So, I then do something like this:
$entityBody=json_decode($data); //$data like the array above
foreach($entityBody as $value){
$email = $value->EMAIL;
//do something with $email
The problem is that the foreach
only runs once and I can successfully process the email address in the first object. But the rest are ignored. So, in the case of the data above, I just get hello@example.com and nothing for info@example.com.
How do I need to adjust my foreach
?
EDIT: Full code here following the janky way that Sendgrid requires you to send it.
foreach($entityBody as $value){
$array[0]['email'] = $value->EMAIL;
$data_json = json_encode($array);
$curl = curl_init();
$headers = array();
$headers[] = 'Accept: application/json';
$headers[] = 'Content-Type: application/json';
$headers[] = "Authorization: Bearer XXXX";
curl_setopt_array($curl, array(
CURLOPT_URL => "https://api.sendgrid.com/v3/contactdb/recipients",
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "POST",
CURLOPT_RETURNTRANSFER => true,
CURLOPT_HTTPHEADER => $headers,
CURLOPT_POSTFIELDS => $data_json,
));
$response = curl_exec($curl);
$err = curl_error($curl);
if ($err) {
die();
}
else{//run good stuff
$new = json_decode( $response, true );
if($new['persisted_recipients'][0]!=""){
$submit = $new['persisted_recipients'][0];
curl_setopt_array($curl, array(
CURLOPT_URL => "https://api.sendgrid.com/v3/contactdb/lists/".$listId."/"."recipients/".$submit,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "POST",
CURLOPT_RETURNTRANSFER => true,
CURLOPT_HTTPHEADER => $headers,
));
$response = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);
if ($err) {
echo "cURL Error #:" . $err;
die();
}
else{
echo("success");
die();
}
}
}
}
First
When using json_decode
, the returned value is an associative array instead of an object.
Therefore, your code $value->EMAIL
is invalid.
Second
The decoded JSON will become something like this:
[ [ "EMAIL" => "hello@example.com", "GENDER" => "Male" ], [ "EMAIL" => "info@example.com", "GENDER" => "Male" ] ]
Therefore, in foreach ($entityBody as $value)
, the $value
points to an array instead of a value.
Hence, $email = $value['EMAIL']
will fail too.
Solution
Use double foreach
:
$data = '[ { "EMAIL": "hello@example.com", "GENDER": "Male" }, { "EMAIL": "info@example.com", "GENDER": "Male" } ]'; $entityBody = json_decode($data); foreach ($entityBody as $value){ // Remember $value === array foreach ($value as $key => $val){ // You can process your data here if ($key === 'EMAIL') echo "Email: {$val}<br>"; else if ($key === 'GENDER') echo "Gender: {$val}<br>"; } }
You can run the above code by copy-pasting it in PhpFiddle
EDIT
Apparently json_decode
returns object for {...}
data format .
So you can use the following code:
foreach ($entityBody as $value){ $email = isset($value->EMAIL) ? $value->EMAIL : false; $gender = isset($value->GENDER) ? $value->GENDER : false; }
Which makes your code perfectly fine.
I think what makes your code only run once is that, in the 2nd iteration of foreach
, the value $value->EMAIL
is not found, therefore throwing error and break out of execution.
Solution is to first check the data using isset()
.
