我有一个问题 因为我现在想要如何在不等于null时隐藏行 因为玩家需要让物品到达那个位置 所以任何帮助都是值得欣赏的
的index.php

玩家按位置查找某些位置是需要的商品ID 作为问题，当玩家将物品放在他的库存中时，我该怎么隐藏呢？
这是游戏的课程
Location.class.php
<?php
require_once ("DBconnection.php");
ini_set('memory_limit', '-1');
ini_set('max_execution_time', 300); //300 seconds = 5 minutes
class Location
{
public $id;
public $Title;
public $Foto_url;
public $Story;
public $Choices = [];
public $Inventory = [];
function LoadFromDb($mysqli, $id)
{
$sql = "SELECT * FROM locations WHERE id=" . $id . ";";
$results = $mysqli->query($sql);
if ($results->num_rows >= 1) {
$record = $results->fetch_assoc();
$this->id = $record['id'];
$this->Title = $record['Title'];
$this->Foto_url = ('<img src="' . $record['Foto_url'] . '">');
$this->Story = $record['Story'];
}
// load choices
$sql = "SELECT * FROM choices WHERE from_id=" . $id . ";";
$results2 = $mysqli->query($sql);
while ($record = $results2->fetch_assoc()) {
$choice = new Choice();
$choice->id = $record['id'];
$choice->from_id = $record['from_id'];
$choice->to_id = $record['to_id'];
$choice->title = $record['title'];
$choice->need_item_id = $record ['need_item_id'];
array_push($this->Choices, $choice);
}
// Load inventory
$sql = "SELECT * FROM inventory";
$results3 = $mysqli->query($sql);
while ($row = $results3->fetch_assoc()) {
$item = new Inventory();
$item->id = $row['id'];
$item->player_id = $row['player_id'];
$item->item_id = $row['item_id'];
$item->space = $row['space'];
array_push($this->Inventory, $item);
}
return true;
}
}
答案 0 :(得分：0)
我关闭了这个，我已经找到了自己的灵魂所以非常赞赏所有的支持
{if $choice->need_item_id}
{foreach $location->Inventory as $itm}
{if $itm->item_id == $choice->need_item_id}
<p class="hide"> YOU HAVE IT </p>
{else}
<p class="item"> Go search the item {$choice->need_item_id}</p>
{/if}
{/foreach}
<!-- So yes then show the choice -->
{/if}
