Question

我有这个钩子

<?php  

use Illuminate\Database\Capsule\Manager as Capsule; 

function hook_productPrice($vars){
    $ProductsPriceArray = Capsule::table("tblpricing")->where("type", "=", "product")->get();
    
    $productPrice = json_decode(json_encode($ProductsPriceArray), true);
    
    return array("productPrice" => $productPrice);
}
add_hook("ClientAreaPage", 1, "hook_productPrice");

当我运行它时，我得到了这个聪明的数组：

$productPrice
Origin: "Smarty object"     
Value
Array (1)
0 => Array (16)
  id => "2"
  type => "product"
  currency => "1"
  relid => "1"
  msetupfee => "0.00"
  qsetupfee => "0.00"
  ssetupfee => "0.00"
  asetupfee => "0.00"
  bsetupfee => "0.00"
  tsetupfee => "0.00"
  monthly => "10.00"
  quarterly => "20.00"
  semiannually => "30.00"
  annually => "40.00"
  biennially => "-1.00"
  triennially => "-1.00"

如您所见，数组的ID为0。如何获取具有与数组相同键的表的ID？

我想使用变量来显示价格，如下所示： $productPrice[2]['monthly']

您需要创建一个新的关联数组，该数组使用id字段作为键。

<?php
use Illuminate\Database\Capsule\Manager as Capsule;

function hook_productPrice($vars)
{
    $ProductsPriceArray = Capsule::table("tblpricing")->where("type", "=", "product")->get();

    $rows = json_decode(json_encode($ProductsPriceArray), true);

    $productPrice = [];
    foreach($rows as $currRow)
    {
        $output[$currRow['id']] = $currRow;
    }

    return array("productPrice" => $productPrice);
}

add_hook("ClientAreaPage", 1, "hook_productPrice");

这是一种常见的模式，您不妨为其创建一个函数并将其粘贴到某处。

<?php
$productPrice = [
    ['id' => 10, 'type' => 'product', 'monthly' => '10.00'],
    ['id' => 11, 'type' => 'product', 'monthly' => '11.00'],
    ['id' => 12, 'type' => 'subscription', 'monthly' => '12.00'],
    ['id' => 13, 'type' => 'service', 'monthly' => '13.00'],
    ['id' => 14, 'type' => 'service', 'monthly' => '14.00']
];

function array_map_by_field($array, $keyField, $valueField=null)
{
    $output = [];

    foreach($array as $currRow)
    {
        if(array_key_exists($keyField, $currRow))
        {
            if(!empty($valueField))
            {
                $output[$currRow[$keyField]] = $currRow[$valueField];
            }
            else
            {
                $output[$currRow[$keyField]] = $currRow;
            }
        }
    }

    return $output;
}

$output = array_map_by_field($productPrice, 'id');
print_r($output);

$output = array_map_by_field($productPrice, 'id', 'monthly');
print_r($output);

WHMCS挂钩将表检索到数组中
