向用户显示数组结果 [英] Display array results to the user

问题描述

我在这里看到并向用户尝试了很多示例，但没有一个对我有用。

I have seen and tried a lot of examples here on display array results to the user but none of them has worked for me.

与我最接近的示例我想寻找的是这样的：

The closest to what I am looking for, I suppose, is this:

如何显示数组结果

再次尝试，但无法正常工作。

Again, tried it but it doesn't work.

它不起作用-意味着页面空白。

It doesn't work - meaning the page is coming up blank.

当我尝试varDump（...）和print_r（...）时，我得到了结果，但我似乎无法向用户显示结果。

When I try varDump(...) and print_r(...), I get results but I can't seem to display the results to the user.

有人知道我需要对下面的代码进行哪些修改才能显示结果sourcename，sourceaddress1和income1？

Does anyone know what modifications I need to make to the code below to get to display the results of sourcename, sourceaddress1 and income1?

$rowIDs = $_POST['rowIDs'];
if (is_array($rowIDs) || is_object($rowIDs))
{
foreach ($rowIDs as $id) {
 $sourcename1 = $_POST['sourcename1'. $id];
 $sourceaddress1 = $_POST['sourceaddress1'. $id];
 $income1 = $_POST['income1'. $id];
 echo $id;
 echo $sourcename;
 echo $sourceaddress1;
 echo $income1;
}

[rowIDs] => 1
[sourcename1] => Array
    (
        [0] => Jane Doe
    )

[sourceaddress1] => Array
    (
        [0] => 123 Main Street
    )

[income1] => Array
    (
        [0] => $89,000.00
    )

推荐答案

$ _ POST ['rowids '] 是一个数字，而不是数组，因此 foreach（$ _ POST ['rowids']为$ id）是错误的。我猜这包含其他输入数组中元素的数量，因此应该为：

$_POST['rowids'] is a number, not an array, so foreach ($_POST['rowids'] as $id) is wrong. I'm guessing this contains the number of elements in the other input arrays, so it should be:

for ($id = 0; $id < $rowIDs; $id++)

您也不应拥有 if（is_array（$ postIDs）|| is_object（$ postIDs）），因为该代码应在输入为数字时运行。

You also shouldn't have if (is_array($postIDs) || is_object($postIDs)), since the code should run when this input is a number.

其他输入是数组，因此您需要使用数组索引来访问它们，而不是字符串连接。

The other inputs are arrays, so you need to use array indexing to access them, not string concatenation.

$sourcename1 = $_POST['sourcename1'][$id];

和其他输入类似。
