I'm trying to dynamically build an array for the Facebook Messenger SDK and populate it with data from a database.
I can't seem to get a properly structured array no matter what I try.
What I need:
$messages = [
"attachment" => [
"type" => "template",
"payload" => [
"template_type" => "generic",
"elements" => [[
"title" => $row['title'],
"item_url" => $row['item_url'],
"image_url" => $row['image_url'],
"subtitle" => $row['subtitle'],
"buttons" => [[
"type" => "web_url",
"url" => "www.google.com",
"title" => "View Website"],
["type" => "postback",
"title" => "Start Chatting",
"payload" => "start"]]
]
]]
]];
I need to create the data inside buttons based on what I have in the database, tried with array_merge and inserting the array as a string:
// Created arrays
if (!empty($row['button1_type'])) {
$buttons[] = array("type" => $row['button1_type'],"url" => $row['button1_url'],
"title" => $row['button1_title'],
"payload" => $row['button1_payload']);
}
if (!empty($row['button2_type'])) {
$buttons[] = array("type" => $row['button2_type'],"url" => $row['button2_url'],
"title" => $row['button2_title'],
"payload" => $row['button2_payload']);
}
// In the case when I had array_merge - $buttons were actually named as $buttons1 and $buttons2
$buttons = array_merge($buttons1, $buttons2);
// Tried to add it as a string
if (!empty($row['button2_type'])) {
$buttons = "\"type\" => ".$row['button2_type'].",\"url\" => .".$row['button2_url'].",
\"title\" => ".$row['button2_title'].",
\"payload\" => ".$row['button2_payload'];
}
$messages = [
"attachment" => [
"type" => "template",
"payload" => [
"template_type" => "generic",
"elements" => [[
"title" => $row['title'],
"item_url" => $row['item_url'],
"image_url" => $row['image_url'],
"subtitle" => $row['subtitle'],
"buttons" => [
$buttons
]
]
]]
]];
Screenshot showing the differences between correct and incorrect:
So basically $buttons are created inside an extra array, how can I get rid of it? Maybe I should change the whole approach?
"buttons" => $buttons?
