php + MySQL 编辑表格数据 [英] php + MySQL editing table data
问题描述
这个问题与 2 个 php 脚本有关.
第一个脚本称为pick_modcontact.php，我在其中选择一个联系人(从电话簿等通讯录中)，然后发布到脚本show_modcontact.php 当我单击pick.modcontact.php 上表单上的提交按钮时.提交表单后，我被带到 show_modcontact.php.由于变量不存在，用户被引导回 pick_modcontact.php
This question is relating to 2 php scripts.
The first script is called pick_modcontact.php where I choose a contact (from a contact book like phone book), then posts to the script show_modcontact.php When I click the submit button on the form on pick.modcontact.php. As a result of submitting the form I am then taken to show_modcontact.php. As the variables are not present the user is directed back to pick_modcontact.php
我不知道如何更正代码以使其显示脚本 show_modcontact.php 的结果
I can not work out how to correct the code so that it will show the results of the script show_modcontact.php
此脚本显示数据库中的所有联系人，该数据库是地址簿"，这部分工作正常.请看下面.名称:pick_modcontact.php
This script shows all contacts in a database which is an "address book" this part works fine. please see below. Name:pick_modcontact.php
if ($_SESSION['valid'] != "yes") {
header( "Location: contact_menu.php");
exit;
}
$db_name = "testDB";
$table_name = "my_contacts";
$connection = @mysql_connect("localhost", "admin", "user") or die(mysql_error());
$db = @mysql_select_db($db_name, $connection) or die(mysql_error());
$sql = "SELECT id, f_name, l_name FROM $table_name ORDER BY f_name";
$result = @mysql_query($sql, $connection) or die(mysql_error());
$num = @mysql_num_rows($result);
if ($num < 1) {
$display_block = "<p><em>Sorry No Results!</em></p>";
} else {
while ($row = mysql_fetch_array($result)) {
$id = $row['id'];
$f_name = $row['f_name'];
$l_name = $row['l_name'];
$option_block .= "<option value\"$id\">$f_name, $l_name</option>";
}
$display_block = "<form method=\"POST\" action=\"show_modcontact.php\">
<p><strong>Contact:</strong>
<select name=\"id\">$option_block</select>
<input type=\"submit\" name=\"submit\" value=\"Select This Contact\"></p>
</form>";
}
?>

推荐答案
我认为您在这里的 value 属性上缺少="符号:
I think you're missing an "=" sign on the value attribute here:
$option_block .= "<option value\"$id\">$f_name, $l_name</option>";
也许你是这个意思?
$option_block .= "<option value=\"$id\">$f_name, $l_name</option>";
