我想从另一个mysql表中填充下拉列表，然后将两个列中的值分配给变量 - 即“select employee，eid，perc from employee”。 “John Doe”将是$ eid = 1234和$ perc = 20.
非常感谢任何帮助！
谢谢 - 马特
以下是我一直在使用的代码：
PHP
<?php
//session_start();
$page_title = 'New invoice';
include ('includes/header.html');
// Check for form submission:
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
require ('mysqli_connect.php'); // Connect to the db.
/*$errors = array(); // Initialize an error array. */
// Invoice number is automatic
if (empty($_POST['op1'])) {
$errors[] = 'Operation needs to be entered.';
} else {
$op1 = mysqli_real_escape_string($dbc, trim($_POST['op1']));
}
// Amount:
if (empty($_POST['amount1'])) {
$errors[] = 'Amount to be charged.';
} else {
$amount1 = mysqli_real_escape_string($dbc, trim($_POST['amount1']));
}
// percentage:
if (empty($_POST['perc'])) {
$errors[] = 'Select a percentage.';
} else {
$perc = mysqli_real_escape_string($dbc, trim($_POST['perc']));
}
// eid:
if (empty($_POST['eid'])) {
$errors[] = 'Enter a techician.';
} else {
$eid = mysqli_real_escape_string($dbc, trim($_POST['eid']));
}
// Stocknum:
if (empty($_POST['stocknum'])) {
$errors[] = 'Need a stock number.';
} else {
$stocknum = mysqli_real_escape_string($dbc, trim($_POST['stocknum']));
}
// Stocknum:
if (empty($_POST['myear'])) {
$errors[] = 'Enter vehicle year.';
} else {
$myear = mysqli_real_escape_string($dbc, trim($_POST['myear']));
}
if (empty($_POST['make'])) {
$errors[] = 'Enter vehicle make.';
} else {
$make = mysqli_real_escape_string($dbc, trim($_POST['make']));
}
if (empty($_POST['model'])) {
$errors[] = 'Enter vehicle model.';
} else {
$model = mysqli_real_escape_string($dbc, trim($_POST['model']));
}
if (empty($_POST['vin'])) {
$errors[] = 'Enter last 6 of the VIN.';
} else {
$vin = mysqli_real_escape_string($dbc, trim($_POST['vin']));
}
if (empty($_POST['mileage'])) {
$errors[] = 'Enter current mileage.';
} else {
$mileage = mysqli_real_escape_string($dbc, trim($_POST['mileage']));
}
if (empty($errors)) { // If everything's OK.
$q = "INSERT INTO `mwcc`.`wp` (`tdate`, `stocknum`, `myear`, `make`, `model`,`vin`, `eid`, `op1`, `amount1`,`mileage`,`ecomm`) VALUES (CURRENT_DATE(), '$stocknum', '$myear', '$make', '$model','$vin', '$eid', '$op1', '$amount1','$mileage', ($amount1*$perc));";
$r = @mysqli_query ($dbc, $q); // Run the query.
//echo ($q);
if ($r) { // If it ran OK.
// Print a message:
echo '<h1>Success!</h1>
<p>Invoice has been created!<br /></p>';
} else { // If it did not run OK.
// Public message:
echo '<h1>System Error</h1>
<p class="error">Uh oh. There has been an error. We apologize for any inconvenience.</p>';
// Debugging message:
echo '<p>' . mysqli_error($dbc) . '<br /><br />Query: ' . $q . '</p>';
} // End of if ($r) IF.
mysqli_close($dbc); // Close the database connection.
exit();
} else { // Report the errors.
echo '<h1>Error!</h1>
<p class="error">The following error(s) occurred:<br />';
foreach ($errors as $msg) { // Print each error.
echo " - $msg<br />\n";
}
echo '</p><p>Please try again.</p><p><br /></p>';
} // End of if (empty($errors)) IF.
mysqli_close($dbc); // Close the database connection.
} // End of the main Submit conditional.

我对你问题的理解。
按照您的提及获取查询结果。select name, eid, perc from employee
对于前端，如果你想在单一选择中传递两个值，那么使用一些独特的分隔符，比如我使用双下划线__
<?php foreach($result as $user): ?>
<select name="eid__perc" >
<option value="<?php $user->eid . '__' . $user->perc?>">
<?php $user->name; //in array case $user['name'];?>
<option>
<select>
<?php endforeach;?>
当您保存信息时，请使用相同的分隔符来爆炸数据，如
list($eid, $perc) = explode('__', $_POST['eid__per'])

您需要使用WHERE条件：
SELECT name, eid, perc FROM employee WHERE eid = ? AND perc = ?
使用mysqli_stmt_bind_param($stmt, 'ss', $eid, $perc);绑定参数。
