[英]PHP table with loop and passing form data to next page
我正在为朋友创建基于Web的联系人列表。 我已经完成了html部分,并且正在处理PHP脚本等。 我将主页面作为表格包含在表单标记中的while循环中。 我需要发生两件事,但不确定如何实现这一目标。
首先,每一行必须有两个提交按钮,一个用于编辑,另一个用于详细信息,并继承全局$ _POST中的值。
其次,列表将大约有300行,因此我正在使用while循环来创建表。
我有工作和传递数据的表单,但它总是传递表的最后一行。 这是表格的主页:
<?php
if
(!isset ($_SESSION['username']))
{
session_start();
}
?>
<html>
<head>
<title>Client Contact List</title>
</head>
<?php
$user1 = implode(',',$_SESSION);
//DB information
require_once('/includes/db.php');
//Declaring edit and details
$edit = "<INPUT type='image' src='/addressbook/images/edit.png' onclick='\addressbook\edit.php'>";
$details = "<INPUT type='image' src='/addressbook/images/contact.gif' name='details' onclick='f1.action='\addressbook\contact_details.php'>";
//Table declarations and such
mysql_connect("$host", "$username", "$password") or die(mysql_error());
mysql_select_db("$db_name")or die("cannot select DB");
$result = mysql_query("SELECT * FROM contacts") or die(mysql_error());
$num=mysql_numrows($result);
$user1 = implode(',',$_SESSION);
$userresults = "SELECT first FROM i_user where userid IN $user1";
$user = mysql_query($userresults);
// print_r ($_SESSION);
// print_r ($_POST);
?>
<body style="background-image: url('Images/background_login.jpg');">
<br><br><br><br><br><br>

<br><br>

$i=0;
while ($i<$num) {
$id = mysql_result($result,$i,"id");
$first = mysql_result($result, $i, "first");
$last = mysql_result($result,$i, "last");
$company = mysql_result($result, $i, "company");
$email1 = mysql_result($result,$i, "email1");
$email2 = mysql_result($result,$i, "email2");
$phone = mysql_result($result,$i, "phone");
$mobile = mysql_result($result,$i, "mobile");
// Print out the contents of each row into a table
echo "<tr><td width = '100'><center><input type='hidden' value='$first' name='first'>";
echo $first;
echo "</center></td><td width = '100'><center><input type='hidden' value='$last' name='last'>";
echo $last;
echo "</center></td><td width = '100'><center><input type='hidden' value='$company' name='company'>";
echo $company;

echo $phone;

echo $mobile;
echo "</center></td><td width = '100'><center>";
echo $edit;
echo "    ";
echo $details;
echo "</td></center></tr>";
echo "<input type='hidden' value='$id name='id'></td>";
$i++;
}
?>

这将直接转到详细信息或编辑页面。 以下是编辑页面。

关于如何完成这项工作的任何想法?
问题是您正在创建大量具有相同名称的元素...每行都有一个由email1,email2,phone,mobile等名称组成的输入。
当您提交表单时,它只使用具有给定名称的最后一个html元素的值。 因此它将始终给您最后一行。
您可以做的就是每个属性只有1个隐藏的输入。 然后,当您选择一行时,可以使用javascript设置隐藏输入的值。
但是,为了使其更简单...您已经将所有用户数据存储在数据库中,因此您无需将所有数据都传递到下一页。 只需将ID传递到下一页,然后在进入下一页时执行选择查询即可获取该用户的所有数据。
这样,您可以为ID提供1个隐藏的输入。 当用户选择要编辑的行时,请使用Javascript设置该输入的值。
每个按钮应如下所示:
echo "<input type=\"button\" onclick=\"document.form.id=$id\">";
输入应如下所示:
echo "<input type=\"hidden\" name=\"id\"/>";
然后在编辑页面上使用:
$id = $_POST['id'];
$query = "SELECT id, first, last, company, email1, email2, phone, mobile
FROM contacts WHERE ID=$id"
$result = mysql_query($query) or die(mysql_error());
$row = mysql_fetch_array($result);
$id = $row['id'];
$first = $row['first'];
etc...
