Question

我正在做一个prestashop模块（我昨天发布了其他问题）。我想现在我遇到了PHP的问题。每次它都告诉我行if($same_puente === false OR $same_patilla === false)...解析错误：语法错误，该行中的意外T_STRING。

<?php

if (!defined('_PS_VERSION_'))
    exit;

class glassOptics extends Module
{
    /* @var boolean error */
    protected $_errors = false;

    /* @var boolean puente */
    public $same_puente = false;

    /* @var boolean patilla */
    public $same_patilla = false;

    /* @var boolean altura cristal */
    public $same_altura_cristal = false;

    /* @var boolean ancho cristal */
    public $same_ancho_cristal = false;

    public function __construct()

我做错了什么？谢谢。

Answer 1

您的$sql声明中有一个额外的结束括号：.') ENGINE='._MYSQL_ENGINE_.'

$sql = 'ALTER TABLE ' . _DB_PREFIX_ . 'product_lang '
.'ADD `dioptrias_izquierdo` decimal(20,6) NOT NULL DEFAULT '.$decimal_zero.','
.'ADD `dioptrias_derecho` decimal(20,6) NOT NULL DEFAULT '.$decimal_zero.','
.'ADD `puente` decimal(20,6) NOT NULL DEFAULT '.$decimal_zero.','
.'ADD `patilla` decimal(20,6) NOT NULL DEFAULT '.$decimal_zero.','
.'ADD `altura_cristal` decimal(20,6) NOT NULL DEFAULT '.$decimal_zero.','
.'ADD `ancho_cristal` decimal(20,6) NOT NULL DEFAULT '.$decimal_zero.''
.') ENGINE='._MYSQL_ENGINE_.' DEFAULT CHARSET=utf8';

Answer 2

你的问题在这里：

<td>

您必须使用foreach ($product_collection as $product){ ... unset($product_collection[$product]); }来获取数组的元素：

$key

因为foreach ($product_collection as $key => $product){ ... unset($product_collection[$key]); }是数组元素的值，而不是键。

意外的T_STRING，但在哪里？
