Question

我有多维数组，这些数组是由动态表单输入生成的，用户可以添加这些数组来添加奖励，工作和教育等内容。

当我收集数组数据以将其推送到.csv时，它会打印出像FinanceWaterlooTheodore2015TreasurerTorontoGary2014这样的数组。

是否有可能标记阵列循环结束的点，以便更清晰，更像是这样的FinanceWaterlooTheodore2015 // TreasurerTorontoGary2014？

$unitLevelInvolvement = $_POST["unitLevelInvolvement"];

$unitInvolvementValue = "";
$i;
foreach($unitLevelInvolvement as $involvement)
{
    $i++;
    $unitInvolvementValue .= $involvement;
}
echo $unitInvolvementValue;

    <div name="unitLevelInvolvement" id="unitLevelInvolvement">
        <input type="text" class="two-lines-textbox" name="unitLevelInvolvement[]" placeholder="Position/Committee" onBlur="this.placeholder='Position/Committee'" onFocus="this.placeholder=''" onKeyUp="checkPage3()" />
        <input type="text" class="two-lines-textbox" name="unitLevelInvolvement[]" id="oectaUnit_1" placeholder="Unit" onBlur="this.placeholder='Unit'" onFocus="this.placeholder=''" onKeyUp="checkPage3()" />

        <div class="clearFix"></div>

        <input type="text" class="two-lines-textbox" name="unitLevelInvolvement[]" id="unitPresident_1" placeholder="Unit President" onBlur="this.placeholder='Unit President'" onFocus="this.placeholder=''" onKeyUp="checkPage3()" />
        <input type="date" class="two-lines-textbox" name="unitLevelInvolvement[]" id="unitYear_1" onKeyUp="checkPage3()" />
        <input type="button" value="+" onClick="addUnitInvolvement()" />
        </div>
    </div><!-- end of unit-level-involvement div-->
    <input type="submit" value="submit" />
</form><!--endForm-->

Answer 1

我知道你试图每4次迭代放一个分隔符（因为你有4个输入）。

注意，只有恰好有4个输入时，此答案才有效。

您可以尝试这样的事情：

$unitLevelInvolvement = $_POST["unitLevelInvolvement"];

$unitInvolvementValue = "";
$i = 0;
foreach($unitLevelInvolvement as $involvement)
    {
        $unitInvolvementValue .= $involvement;
        $i++;
        if($i % 4 == 0){
          $unitInvolvementValue .= "//";
        }
    }
echo $unitInvolvementValue;

首先，您需要创建＆＃34;群组＆＃34;因为你还没有。您可以通过创建具有name属性的多维数组来完成此操作。你的HTML看起来像这样：

<div name="unitLevelInvolvement" id="unitLevelInvolvement">
    <input type="text" class="two-lines-textbox" name="unitLevelInvolvement['group1'][]" placeholder="Position/Committee" onBlur="this.placeholder='Position/Committee'" onFocus="this.placeholder=''" onKeyUp="checkPage3()" />
    <input type="text" class="two-lines-textbox" name="unitLevelInvolvement['group1'][]" id="oectaUnit_1" placeholder="Unit" onBlur="this.placeholder='Unit'" onFocus="this.placeholder=''" onKeyUp="checkPage3()" />

    <div class="clearFix"></div>

    <input type="text" class="two-lines-textbox" name="unitLevelInvolvement['group2'][]" id="unitPresident_1" placeholder="Unit President" onBlur="this.placeholder='Unit President'" onFocus="this.placeholder=''" onKeyUp="checkPage3()" />
    <input type="date" class="two-lines-textbox" name="unitLevelInvolvement['group2'][]" id="unitYear_1" onKeyUp="checkPage3()" />
    <input type="button" value="+" onClick="addUnitInvolvement()" />
    </div>
</div><!-- end of unit-level-involvement div-->

然后你可以像这样迭代数组：

$unitInvolvementValue = array();
foreach($unitLevelInvolvement as $group)
{
    $groupInvolvement = "";
    foreach($group as $involvement)
    {
        $groupInvolvement .= $involvement;
    }
    $unitInvolvementValue[] = $groupInvolvement;
}

echo implode("//", $unitInvolvementValue );

我使用implode()方法，因为它只在值之间添加了分隔符，而不是在字符串的开头或结尾。
