[英]Referencing variables in nested arrays
I'm trying to reference the "suggested" variable within this nested array as it gets spit out of a for loop. 我试图在此嵌套数组中引用“建议”变量,因为它会从for循环中吐出。 $_SESSION["products"]->suggested, did not work. $ _SESSION [“ products”]->建议,不起作用。 There are other questions like this on SO but the answers are hard to follow. 在SO上还有其他类似的问题,但是答案很难遵循。 The for loop is below. for循环如下。
array(1) {
["products"]=>
array(1) {
[0]=>
array(9) {
["name"]=>
string(20) "m10x1-5-001 IVB bolt"
["code"]=>
string(11) "m10x1-5-001"
["qty"]=>
string(1) "1"
["weight"]=>
string(3) ".03"
["price"]=>
string(5) "37.00"
["image"]=>
string(80) "/images/ProductPhotosLR/m101-5-001/m10x1-5-001-S.jpg"
["description"]=>
string(39) "This is a short description of my item."
["suggested"]=>
string(18) "IVB-METRIC-INSTALL"
["suggestedtext"]=>
string(80) "First time owners of ....."
}
}
}
The loop I'm trying to use: (every item in a cart session would have a suggested item attached potentially) for loop works fine, if statement is broken. 我正在尝试使用的循环:(如果购物车中的每个项目都可能附有建议的项目)for循环可以很好地工作,如果语句已损坏。
if(!empty($_SESSION["products"]->suggested)) {
echo '<div id="products-wrapper"><h1>Suggested Items</h1><div class="view-cart">';
echo '<table width="750" cellpadding="0" cellspacing="0" style="text-align:center;padding:5px;">';
foreach ($_SESSION["products"] as $cart_itm)
{
echo '<tr><td>'.$cart_itm['suggested'].' '.$cart_itm['suggestedtext'].'</td></tr>';
}
echo '</table></div></div>';
}
You can "chain" keys or indexes of nested arrays just like you would access properties of an object 您可以“链接”嵌套数组的键或索引,就像访问对象的属性一样
$_SESSION["products"]["suggested"]
