Question

我在数组中有一些表单值，需要将它们放入表行中，并且可以使用一些指导/帮助。以下是我所拥有的，并且不确定我是否在正确的道路上：

//These are my form values
$part = $_POST['part'];
$rel = $_POST['rel'];
$chart = $_POST['chart'];
$dob = $_POST['dob'];
$age = $_POST['age'];
$gender = $_POST['gender'];

//If participant (part) is not empty, start building the table  
if ($part != "") {

//The table header (not worried about <td>/<th> semantics right now
$participants = "Participants<table border='1'>
    <tr><td>Name</td><td>Relationship</td><td>Chart #</td><td>DOB</td> <td>Age</td><td>Gender</td></tr>";

//This is where I am lost...looping over and outputting on a row by row basis       
foreach($part as $row) {
    $participants_table = "<tr><td>". $part . "</td><td>". $rel ."</td><td>". $chart ."</td><td>". $dob ."</td><td>". $age ."</td><td>". $gender ."</td></tr>";
    }
} else {
//If there are no names in the participant column(s), display the following
$participants = "No Other Participants";
$participants_table = "";
}

// print_r的输出接下来，以下内容可能会过大，但请注意：Array ( [0] => Christine Eubanks [1] => Ariel Eubanks [2] => Synthia Clow [3] => [4] => [5] => [6] => ) Array ( [0] => Wife [1] => Daughter [2] => Daughter [3] => [4] => [5] => [6] => ) Array ( [0] => 123456 [1] => 654321 [2] => 543210 [3] => [4] => [5] => [6] => ) Array ( [0] => 04/03/1974 [1] => 07/21/2004 [2] => 12/28/1995 [3] => [4] => [5] => [6] => ) Array ( [0] => 44 [1] => 14 [2] => 22 [3] => [4] => [5] => [6] => ) Array ( [0] => F [1] => F [2] => F [3] => [4] => [5] => [6] => ) Array ( [0] => Christine Eubanks [1] => Ariel Eubanks [2] => Synthia Clow [3] => [4] => [5] => [6] => ) Array ( [0] => Wife [1] => Daughter [2] => Daughter [3] => [4] => [5] => [6] => ) Array ( [0] => 123456 [1] => 654321 [2] => 543210 [3] => [4] => [5] => [6] => ) Array ( [0] => 04/03/1974 [1] => 07/21/2004 [2] => 12/28/1995 [3] => [4] => [5] => [6] => ) Array ( [0] => 44 [1] => 14 [2] => 22 [3] => [4] => [5] => [6] => ) Array ( [0] => F [1] => F [2] => F [3] => [4] => [5] => [6] => ) Array ( [0] => Christine Eubanks [1] => Ariel Eubanks [2] => Synthia Clow [3] => [4] => [5] => [6] => ) Array ( [0] => Wife [1] => Daughter [2] => Daughter [3] => [4] => [5] => [6] => ) Array ( [0] => 123456 [1] => 654321 [2] => 543210 [3] => [4] => [5] => [6] => ) Array ( [0] => 04/03/1974 [1] => 07/21/2004 [2] => 12/28/1995 [3] => [4] => [5] => [6] => ) Array ( [0] => 44 [1] => 14 [2] => 22 [3] => [4] => [5] => [6] => ) Array ( [0] => F [1] => F [2] => F [3] => [4] => [5] => [6] => ) Array ( [0] => Christine Eubanks [1] => Ariel Eubanks [2] => Synthia Clow [3] => [4] => [5] => [6] => ) Array ( [0] => Wife [1] => Daughter [2] => Daughter [3] => [4] => [5] => [6] => ) Array ( [0] => 123456 [1] => 654321 [2] => 543210 [3] => [4] => [5] => [6] => ) Array ( [0] => 04/03/1974 [1] => 07/21/2004 [2] => 12/28/1995 [3] => [4] => [5] => [6] => ) Array ( [0] => 44 [1] => 14 [2] => 22 [3] => [4] => [5] => [6] => ) Array ( [0] => F [1] => F [2] => F [3] => [4] => [5] => [6] => ) Array ( [0] => Christine Eubanks [1] => Ariel Eubanks [2] => Synthia Clow [3] => [4] => [5] => [6] => ) Array ( [0] => Wife [1] => Daughter [2] => Daughter [3] => [4] => [5] => [6] => ) Array ( [0] => 123456 [1] => 654321 [2] => 543210 [3] => [4] => [5] => [6] => ) Array ( [0] => 04/03/1974 [1] => 07/21/2004 [2] => 12/28/1995 [3] => [4] => [5] => [6] => ) Array ( [0] => 44 [1] => 14 [2] => 22 [3] => [4] => [5] => [6] => ) Array ( [0] => F [1] => F [2] => F [3] => [4] => [5] => [6] => ) Array ( [0] => Christine Eubanks [1] => Ariel Eubanks [2] => Synthia Clow [3] => [4] => [5] => [6] => ) Array ( [0] => Wife [1] => Daughter [2] => Daughter [3] => [4] => [5] => [6] => ) Array ( [0] => 123456 [1] => 654321 [2] => 543210 [3] => [4] => [5] => [6] => ) Array ( [0] => 04/03/1974 [1] => 07/21/2004 [2] => 12/28/1995 [3] => [4] => [5] => [6] => ) Array ( [0] => 44 [1] => 14 [2] => 22 [3] => [4] => [5] => [6] => ) Array ( [0] => F [1] => F [2] => F [3] => [4] => [5] => [6] => ) Array ( [0] => Christine Eubanks [1] => Ariel Eubanks [2] => Synthia Clow [3] => [4] => [5] => [6] => ) Array ( [0] => Wife [1] => Daughter [2] => Daughter [3] => [4] => [5] => [6] => ) Array ( [0] => 123456 [1] => 654321 [2] => 543210 [3] => [4] => [5] => [6] => ) Array ( [0] => 04/03/1974 [1] => 07/21/2004 [2] => 12/28/1995 [3] => [4] => [5] => [6] => ) Array ( [0] => 44 [1] => 14 [2] => 22 [3] => [4] => [5] => [6] => ) Array ( [0] => F [1] => F [2] => F [3] => [4] => [5] => [6] => )

Answer 1

无论何时接收到数组，都必须使用for循环或foreach循环对其进行循环，因为您已经为$ part = $ _POST ['part']等变量分配了值；它不存在，它将始终引发错误。而且在您的代码中$ part不是要循环的数组。

<?php
//$part = $_POST[];
$part = array(
  array('part', 'rel', 'chart', 'dob', 'age', 'gender'),
  array('part1', 'rel1', 'chart1', 'dob1', 'age1', 'gender1')
);

if ($part != "") {
  //The table header (not worried about <td>/<th> semantics right now
  $participants = "Participants<table border='1'><tr><td>Name</td><td>Relationship</td><td>Chart #</td><td>DOB</td> <td>Age</td><td>Gender</td></tr>";

  //This is where I am lost...looping over and outputting on a row by row basis       
  foreach ($part as $value) {
    $participants .= "<tr><td>" . $value[0] . "</td><td>" . $value[1] . "</td><td>" . $value[2] . "</td><td>" . $value[3] . "</td><td>" . $value[4] . "</td><td>" . $value[5] . "</td></tr>";
  }

  $participants .= '</table>';
}
else {
  //If there are no names in the participant column(s), display the following
  $participants = "No Other Participants";
}
echo $participants;
?>

Answer 2

无论您在print_r中使用什么，我在这里都将重点关注此解决方案。因此，如果您进行了print_r($_POST)，则可以使用：

我使用htmlspecialchars清理字符串以防止讨厌的xss注入。

<?php

foreach($_POST as $row) {
    $part = htmlspecialchars($row[0], ENT_QUOTES, 'UTF-8');
    $rel = htmlspecialchars($row[1], ENT_QUOTES, 'UTF-8');
    $chart = htmlspecialchars($row[2], ENT_QUOTES, 'UTF-8');
    $dob = htmlspecialchars($row[3], ENT_QUOTES, 'UTF-8');
    $age = htmlspecialchars($row[4], ENT_QUOTES, 'UTF-8');
    $gender = htmlspecialchars($row[5], ENT_QUOTES, 'UTF-8');
    $unkown = htmlspecialchars($row[6], ENT_QUOTES, 'UTF-8'); //your output shows a [6]'th element

    $participants_table = "<tr><td>". $part . "</td><td>". $rel ."</td><td>". $chart ."</td><td>". $dob ."</td><td>". $age ."</td><td>". $gender ."</td></tr>";

}

对我来说最有趣的是，在您的数据转储中，没有关联键，因此为什么要使用数字键

PHP数组到表行
