Question

当我运行下面提到的代码时，我得到错误：

Undefined offset:1 for $productSize = $product[1];//pack size.

我无法从数据库中获取数据。它返回null数组。

代码：

<?php
    header('Content-type: application/json');
    $con = mysql_connect('localhost', 'root', 'pass');
    mysql_select_db('callingapp') or die('no connection');
    if ($_SERVER['REQUEST_METHOD'] == "POST") {
        $currentDate       = date("Y-m-d H:i:s");
        /* Convert into sql time */
        $currentDate       = strtotime($currentDate);
        $currentDateTime   = time_php2sql($currentDate);
        // Get data
        $currentUserId     = isset($_POST['id']) ? mysql_real_escape_string($_POST['id']) : ""; //TelecallerId
        $callerId          = isset($_POST['callerid']) ? mysql_real_escape_string($_POST['callerid']) : ""; //id of lead /student
        $status            = isset($_POST['status']) ? mysql_real_escape_string($_POST['status']) : ""; //status new call,follow up ,schedule
        $notes             = isset($_POST['notes']) ? mysql_real_escape_string($_POST['notes']) : ""; //comments
        $callstatus        = isset($_POST['callstatus']) ? mysql_real_escape_string($_POST['callstatus']) : ""; //answered/notanswered
        $callstatus        = strtolower($callstatus);
        $callstatus        = preg_replace('/\s+/', '', $callstatus);
        $answered          = isset($_POST['answered']) ? mysql_real_escape_string($_POST['answered']) : ""; //answer status if call status is answered
        $not_answer        = isset($_POST['not_answer']) ? mysql_real_escape_string($_POST['not_answer']) : ""; //notanswer status if call status is notanswered
        $didnotlikestatus  = isset($_POST['didnotlikestatus']) ? mysql_real_escape_string($_POST['didnotlikestatus']) : ""; //didnot like status if call status is answered and did not like
        $datePost          = isset($_POST['date']) ? mysql_real_escape_string($_POST['date']) : "";

        $dates             = strtotime($datePost);
        $date              = time_php2sql($dates); //convert it into unix format
        $datetimetotinsert = isset($_POST['dateTime']) ? mysql_real_escape_string($_POST['dateTime']) : ""; //Call later date and time 
        /* Convert into sql time */
        $time              = strtotime($datetimetotinsert);
        $dateTime          = time_php2sql($time); //convert it into unix format
        $OrderDate         = isset($_POST['todayDateTime']) ? mysql_real_escape_string($_POST['todayDateTime']) : ""; //order date
        $productnameorder  = isset($_POST['productnameorder']) ? mysql_real_escape_string($_POST['productnameorder']) : ""; //name of product ordered
        print $productquantity = isset($_POST['productqty']) ? mysql_real_escape_string($_POST['productqty']) : ""; //Quantity of product ordered
        $product_name     = explode(",", $productnameorder); //explode product name and pack size
        $finalArray       = array();
        $product_quantity = explode(",", $productquantity);
        foreach ($product_name as $data) {
            print_r($product_name);

            $innerArray        = array();
            $product           = explode(" ", $data);
            $productName       = $product[0]; //product name
            $productSize       = $product[1]; //pack size
            //get product id,price from pm_productmaster_cstm and pp_productpricing_cstm respectively
            $sqlProductDetails = "SELECT pm.id_c as id, pm.`status_c` AS pmStatus, pp.price_c, pp.`status_c` AS ppStatus,pp.id_c as pricingID 
    FROM `pm_productmaster_cstm` AS pm LEFT JOIN `pp_productpricing_cstm` AS pp ON pp.pm_productmaster_id_c = pm.id_c
    WHERE pm.`productname_c` = '{$productName}' AND pm.`numdays_c` = '{$productSize}' AND pm.`status_c` = '1'  AND pp.`status_c`= '1' ";
        }
    }

根据OP，print_r($product)的输出给出：

Array (
    [0] =>
)

因此导致的问题是因为数组索引超出范围。数组索引零基于。因此，获取数组第一个值的解决方案是使用：

$productSize = $product[0];

未定义的偏移量：PHP代码中的1
