【问题讨论】：

你能举一个这句话的例子吗：“我会让一个进入，但不让另一个进入，或者反过来。”在这里稍微详细一点会有所帮助。您好，感谢您的回复。如果我将插入添加到复选框值中，它会将其添加到数据库中，但如果我将插入添加到输入值中，它将添加输入值而不是复选框。是的，很明显，在您的 php 代码中，您需要在每个“$sql =”语句之后添加“mysql_query”块。您可以粘贴您的 php 代码，以便我们进行更正。嗨，谢谢，我解决了。我刚刚添加了 '".$chk." " 在一行中如下 $sql = ("INSERT INTO 供应商 (company_name, supplier_id, phone_no, contact_person, cell, email, based, address, bee_level, notes, added_by, trade)VALUES('$_POST[company_name]',' $_POST[supplier_id]','$_POST[tel]','$_POST[contact]','$_POST[cell]','$_POST[email]','$_POST[based]','$_POST [address]','$_POST[bee]','$_POST[notes]','$_POST[added_by]','".$chk."' )"); o jan 和 () 在末尾和我的 sql 语句的开头。 【参考方案1】：

这会起作用，但它有点做作......

<?php

$url='localhost';
$username = "root";
$password = "";
$dbname = "helpdesk";
$checkbox1 = $_POST['trade'];
$chk=""; 

foreach($checkbox1 as $chk1) 
 
  $chk.= $chk1.","; 


$conn = mysqli_connect($url, $username, $password, $dbname);
if (!$conn) 
  die("Connection failed: " . mysqli_connect_error());


$sql1 = "INSERT INTO suppliers (trade)VALUES( '$chk' );";
$sql2 = "INSERT INTO suppliers (company_name, supplier_id, telephone_no, contact_person, cell, email, based, address, bee_level, notes, added_by) VALUES ('$_POST[company_name]','$_POST[supplier_id]','$_POST[tel]','$_POST[contact]','$_POST[cell]','$_POST[email]','$_POST[based]','$_POST[address]','$_POST[bee]','$_POST[notes]','$_POST[added_by]')";

ini_set('display_errors',10);

// Aliases for form selection
$company_name = $_POST["company_name"];
$supplier_id = $_POST["supplier_id"];
$tel = $_POST["tel"];
$contact = $_POST["contact"];
$cell = $_POST["cell"];
$email = $_POST["email"];
$based = $_POST["based"];
$address = $_POST["address"];
$bee = $_POST["bee"];
$notes = $_POST["notes"];
$added_by = $_POST["added_by"];

// Your first query
if (mysqli_query($conn, $sql1))

  $last_id = mysqli_insert_id($conn);
  echo "New record created successfully. Last inserted ID is: " .      $last_id;
  echo "<script>setTimeout(\"location.href = 'addsupplier.php';\",2500);</script>";
  unset($_POST);
 else 
  echo "Error: " . $sql . "<br>" . mysqli_error($conn);
; 
mysqli_close($conn);

// Your second query.
if (mysqli_query($conn, $sql2))

  $last_id = mysqli_insert_id($conn);
  echo "New record created successfully. Last inserted ID is: " .    $last_id;
  echo "<script>setTimeout(\"location.href = 'addsupplier.php';\",2500);</script>";
