这是我的foreach循环,用于获取多维数组中的值
$_coloredvariables = get_post_meta( $post->ID, '_coloredvariables', true );
foreach ($_coloredvariables as $key => $value) {
var_dump($value);
}
哪个输出:
array
'label' => string 'Color' (length=5)
'size' => string 'small' (length=5)
'displaytype' => string 'square' (length=6)
'values' =>
array
'dark-night-angel' =>
array
'type' => string 'Image' (length=5)
'color' => string '#2c4065' (length=7)
'image' => string '' (length=0)
'forest-green' =>
array
'type' => string 'Color' (length=5)
'color' => string '#285d5f' (length=7)
'image' => string '' (length=0)
'voilet' =>
array
'type' => string 'Color' (length=5)
'color' => string '#6539c9' (length=7)
'image' => string '' (length=0)
'canary-yellow' =>
array
'type' => string 'Color' (length=5)
'color' => string 'grey' (length=4)
'image' => string '' (length=0)
然后只获得值数组我可以这样做:
foreach ($_coloredvariables as $key => $value) {
var_dump($value['values']);
}
输出:
array
'dark-night-angel' =>
array
'type' => string 'Image' (length=5)
'color' => string '#2c4065' (length=7)
'image' => string '' (length=0)
'forest-green' =>
array
'type' => string 'Color' (length=5)
'color' => string '#285d5f' (length=7)
'image' => string '' (length=0)
'voilet' =>
array
'type' => string 'Color' (length=5)
'color' => string '#6539c9' (length=7)
'image' => string '' (length=0)
'canary-yellow' =>
array
'type' => string 'Color' (length=5)
'color' => string 'grey' (length=4)
'image' => string '' (length=0)
我无法弄清楚如何在数组结构中获取这些元素
“暗一夜天使”, “森林绿”, “voilet” “淡黄色的”
不使用特定名称:
var_dump($value['values']['dark-night-angel'])
更有活力的东西,当然这不起作用:
var_dump($value['values'][0][0]);

您可以在foreach循环中添加foreach循环。
foreach($_coloredvariables as $key => $value) {
foreach($value['values'] as $valkey => $values) {
var_dump($valkey, $values);
}
}

对于1 $value
(可能在那个foreach中):
$colors = array_keys($value['values']);
如果您想要$_coloredvariables
中所有值中的所有颜色,那么您需要这样的预测:
$colors = array();
foreach ($_coloredvariables as $key => $value) {
$colors = array_merge($colors, array_keys($value['values']));
}
此仅返回颜色键。不是这些元素的内容(type
,color
& image
)。
这就是你需要的......?
