slack, php and json - Valid Markup for iterating app selections - php

Question

I've been trying to create a slack app which takes the basic information of the name and sku of the product and places it within a select box that appears in slack. Unfortunately my code to populate the valid json is going wrong somewhere when i try to itterate using a loop.
Valid Json is here:
{
"text": "Great! You want to find something!",
"attachments": [
{
"text": "Please type what you want to find",
"fallback": "Sorry! Cant do that at the moment!",
"callback_id": "cg_selectproduct",
"color": "#3AA3E3",
"attachment_type": "default",
"actions": [
{
"name": "cg_choice",
"text": "Find Product",
"type": "select",
"options": [
{
"text": "option1",
"value": "option1"
},
{
"text": "option2",
"value": "option2"
},
{
"text": "option3",
"value": "option3"
}]
}
]
}
]
}
This works perfectly fine without the iteration. I have no issues if i tell the app to go here. It displays all options correctly.
Invalid PHP
$check = ($dbh->prepare("SELECT * FROM product_list WHERE FAMILY='PARENT'"));
$check->execute();
$row = $check->fetchAll();
// execute a pdo search to find all product parents
$jsonInput = "";
foreach($row as $rows){
$jsonInput .= '"text"=>"' . $rows['PRODUCT_NAME'] . '", "value" => "' . $rows['SKU'] . '",';
}
$jsonInput = rtrim($jsonInput, ',');
//Create an iterative string which will contain the product names and skus, removing the comma at the end.
header('Content-Type: application/json');
//Set the content type to json
$optionSelect = array(
"text" => "Great! You want to find something!",
"attachments" =>array(
"text" => "Please type what you want to find",
"fallback" => "Sorry! Cant do that at the moment!",
"callback_id" => "cg_selectproduct",
"color"=> "#3AA3E3",
"attachment_type" => "default",
"actions" => array(
"name" => "cg_choice",
"text" => "Find Product",
"type" => "select",
"options" => array($jsonInput)
)
)
);
//Create and itterate the options for the selection so it's populated
print_r(json_encode($optionSelect));
//print to show json
I'm not 100% sure where i'm going wrong with this. Maybe i'm thinking about a minor part a little too much. Can anyone here help me with where i'm going wrong?

Answer 1

$jsonInput = [];
foreach($row as $rows) {
$jsonInput[] = array(
'text' => $rows['PRODUCT_NAME'],
'value' => $rows['SKU']
);
}
// ...........
"options" => $jsonInput
