我问的每个人都发现这个问题太具挑战性，希望这里有人可以处理它。
我有一个程序可以生成带有用户输入的名片（名称，标题，地址等）。
我还有一个页面，用户可以在其中配置信息在卡片上的显示方式：CorHttpd Cordova Plugin
使用这些配置，以便如果某些字段为空，则其他字段可以移动以取代空字段。
我们应该如何期待它的运作： 选中“字段”时，表示它可以移动。箭头表示它应该移动的位置。例如，名称应向下移动，标题应向上移动。因此，如果输入中没有给出名称，并且有标题，那么标题将会上升并占据名称的空白区域。
如果未选中某个字段，则表示它无法移动，并且字段无法占据其位置（或跨越它）。因此，例如，如果有一个名称，但没有标题，那么名称将下去取得标题的位置，但不能再进一步下降（即使“办公室电话”是空的，所以会有一个空白名片上的空间。）
使用相同的配置示例，如果用户没有输入移动电话和电子邮件，但输入了最后2个字段（地址1和城市，州，邮政编码），则最后2个字段将上升2个字段，拿走手机和电子邮件的地方。
假设我的名片输入是：
(checked, pointing down) Name: Dan
(checked, pointing up) Title:
(unchecked) Office tel:
(checked, pointing up) Mobile tel:
(checked, pointing up) Email: grwgwr@geffw.com
(checked, pointing up) Address 1: 12 jal
(checked, pointing up) City, state, zip: NYC, NY, 12345
我需要的结果renderValues数组如下所示：
(
[0] =>
[1] => Dan
[2] =>
[3] => grwgwr@geffw.com
[4] => 12 jal
[5] => NYC, NY, 12345
[6] =>
)
这不是我的代码所得到的。你可能不需要它，它可能会更加混乱，但这是我到目前为止所尝试的内容：
foreach ($renderBlocksPropsByOrder as $blockID => $field) {
$direction = $field['blankSensitivityDirection'];
// note: if a field is not blank sensitive, it is locked
if (trim($renderValues[$blockID]) == '' && $field['isBlankSensitive'] == '1') {
// if ($renderBlocksPropsByOrder[$blockID + 1])
// the field(s) around this field can take its position
// ??? if the field above is pointing down and the field below is pointing up, give priority to the field down ???
} else if (trim($renderValues[$blockID]) == '' && $field['isBlankSensitive'] == '0') {
// fields above this field cannot go down past it even if it's empty, but they can all go down until they reach it
// fields below this field cannot go up past it even if it's empty, but they can all go up until they reach it
// this field will be a "blank" space field
} else if (trim($renderValues[$blockID]) != '' && $field['isBlankSensitive'] == '0') {
// similar as the above case, except this field won't be a blank space
} else if (trim($renderValues[$blockID]) != '' && $field['isBlankSensitive'] == '1') {
// this field should move if it can
if ($direction === 'down') {
// check fields below it to move it to the lowest available spot
// (fields below have a higher index)
for ($i = $blockID + 1; $i < $numBlocks; $i++) {
if (trim($renderValues[$i]) != '') {
// prevent stepping over a field that has a value
break;
}
if (trim($renderValues[$i]) == '' && $renderBlocksPropsByOrder[$i]['isBlankSensitive'] == '1') {
$renderValues[$i] = $renderValues[$blockID];
$renderValues[$blockID] = ' ';
break;
}
}
} else if ($direction === 'up') {
// check fields above it to move it to the highest available spot
// (fields above have a lower index)
for ($i = $blockID - 1; $i >= 0; $i--) {
if (trim($renderValues[$i]) != '') {
// prevent stepping over a field that has a value
break;
}
if (trim($renderValues[$i]) == '' && $renderBlocksPropsByOrder[$i]['isBlankSensitive'] == '1') {
$renderValues[$i] = $renderValues[$blockID];
$renderValues[$blockID] = ' ';
break;
}
}
}
}
}
数组renderBlocksPropsByOrder具有每个字段的配置：
(
[0] => Array
(
[blockID] => 0
[isBlankSensitive] => 1
[blankSensitivityDirection] => down
)
[1] => Array
(
[blockID] => 1
[isBlankSensitive] => 1
[blankSensitivityDirection] => up
)
[2] => Array
(
[blockID] => 2
[isBlankSensitive] => 0
[blankSensitivityDirection] => ''
)
[3] => Array
(
[blockID] => 3
[isBlankSensitive] => 1
[blankSensitivityDirection] => up
)
[4] => Array
(
[blockID] => 4
[isBlankSensitive] => 1
[blankSensitivityDirection] => up
)
[5] => Array
(
[blockID] => 5
[isBlankSensitive] => 1
[blankSensitivityDirection] => up
)
[6] => Array
(
[blockID] => 6
[isBlankSensitive] => 1
[blankSensitivityDirection] => up
)
)
RenderValues具有每个字段的值。初始renderValues数组看起来像：
(
[0] => Dan
[1] =>
[2] =>
[3] =>
[4] => grwgwr@geffw.com
[5] => 12 jal
[6] => NYC, NY, 12345
)
我已经花了很长时间在这上面，任何可以帮助我前进的帮助都会非常非常感激。
如果这种方式过于复杂，我会采取任何建议，以另一种用户友好的方式配置名片。

我希望它能解决你的问题（发现这是一个有趣的案例，早上花了一部分时间）
编辑：只是重新制作了函数和模型，因此它会按预期迭代，以便反复查看整个模型，直到每个插槽都正确排序。
// Card Model
$card = array (
1 => array(
"label"=>"Name",
"canmove"=>"down",
"value"=>"Dan"
),
2 => array(
"label"=>"Title",
"canmove"=>"up",
"value"=>""
),
3 => array(
"label"=>"Office Tel",
"canmove"=>"n",
"value"=>""
),
4 => array(
"label"=>"Mobile Tel",
"canmove"=>"up",
"value"=>""
),
5 => array(
"label"=>"Email",
"canmove"=>"up",
"value"=>"grwgwr@geffw.com"
),
6 => array(
"label"=>"Address 1",
"canmove"=>"up",
"value"=>"12 jal"
),
7 => array(
"label"=>"City, State, Zip",
"canmove"=>"up",
"value"=>"NYC, NY, 12345"
),
);
// Render it!
$renderedCard = renderCard($card);
// Testing
foreach($renderedCard as $key=>$values) {
echo "[".$key."] ".$values['label'].": ".$values['value']."<br>";
}
// Structural view
echo "<pre>";
print_r($renderedCard);
echo "</pre>";
// This function nullifies every slot with empty 'value', except if
// its 'canmove' is 'n', which may keep intact
function clearCard($card) {
$newCard = array();
foreach ($card as $slot=>$props) {
$props['value'] != '' || $props['canmove'] == 'n' ?
$newCard[$slot] = $card[$slot] :
$newCard[$slot] = null;
}
return $newCard;
}
// This function will move each slot to occupy the empty ones, based
// on 'canmove' criteria
function renderCard($card) {
$cleanCard = clearCard($card);
$refactor = 0;
// iterates over cleanCard to perform a 'bubble sort'
while ($refactor < count($cleanCard)) {
foreach ($cleanCard as $slot => $props) {
switch ($props['canmove']) {
// if 'up', and upward slot is empty,
// occupy its place and null itself next
case 'up':
// if it overflows the card array offset, breaks
if ($slot-1 <= 0) break;
// if upper 'value's null, means it can be filled!
if ($cleanCard[$slot-1] == null) {
$cleanCard[$slot-1] = $cleanCard[$slot];
$cleanCard[$slot] = null;
}
break;
// same as 'up', but checking downward field
case 'down':
if ($slot+1 > count($cleanCard)) break;
if ($cleanCard[$slot+1] == null) {
$cleanCard[$slot+1] = $cleanCard[$slot];
$cleanCard[$slot] = null;
}
break;
}
}
// increment the refactor to loop while over cleanCard count
$refactor++;
}
// when finished, returns the rendered array
return $cleanCard;
}
<强> OUTPUTS
1）关注你问题的模型：
[1] :
[2] Name: Dan
[3] Office Tel:
[4] Email: grwgwr@geffw.com
[5] Address 1: 12 jal
[6] City, State, Zip: NYC, NY, 12345
[7] :
2）添加“标题”（CEO）：
[1] Name: Dan
[2] Title: CEO
[3] Office Tel:
[4] Email: grwgwr@geffw.com
[5] Address 1: 12 jal
[6] City, State, Zip: NYC, NY, 12345
[7] :
3）现在，还有一部“移动电话”：
[1] Name: Dan
[2] Title: CEO
[3] Office Tel:
[4] Mobile Tel: 55559999
[5] Email: grwgwr@geffw.com
[6] Address 1: 12 jal
[7] City, State, Zip: NYC, NY, 12345
4）如果您有“标题”但没有“名称”怎么办？我们来看看：
[1] Title: CEO
[2] :
[3] Office Tel:
[4] Email: grwgwr@geffw.com
[5] Address 1: 12 jal
[6] City, State, Zip: NYC, NY, 12345
[7] :
5）现在让我们删除“地址1”，因此“城市，州，邮编”应该取而代之：
[1] Title: CEO
[2] :
[3] Office Tel:
[4] Email: grwgwr@geffw.com
[5] City, State, Zip: NYC, NY, 12345
[6] :
[7] :
6）[编辑]将“电子邮件”字段设置为canmove“向下”，以及“地址1”和“城市，州，邮编”设置为空值，因此电子邮件应将其全部移动下来！：
[1] Title: CEO
[2] :
[3] Office Tel:
[4] :
[5] :
[6] :
[7] Email: grwgwr@geffw.com
随意进行其他测试并给出反馈，我很开心这样做！
