我有一个通过查询字符串生成的表单 在页面上，大量数据放在表单中。
我将它们放在表格中并一起更新。 现在我遇到两个问题：
以下是代码：
include_once 'header.php';
include_once 'lab-sidebar.php';
include_once 'conn.php';
include_once 'functions.php';
$data = display_conditional_data(" name LIKE '".$_REQUEST['alpha']."%' order by name asc ",'tb_test');
$sample_type = dis_all_data('tb_sample_type');
$departments = dis_all_data('tb_test_method');
$testconditions = dis_all_data('tb_test_conditions');
$display_data = display_data('id',$_SESSION['user_id'],'tb_labs');
if(isset($_POST['btnSubmit'])){
$sql = "insert into test_menu_details ( test_id ,sample_type , price, discounted_price, lab_id, dep_id, reporting_time, automatic, remarks , city,testcondition) values ";
$count_length = count($_POST['price']);
for($i = 0 ; $i< $count_length; $i++){
if($_POST['price'][$i] != ''){
$sql .= "('".$_POST['test_name'][$i]."','" .$_POST['sample_type'][$i]."','".$_POST['price'][$i]."','".$_POST['discount_price'][$i]."','".$_SESSION['user_id']."','".$_POST['departments'][$i]."','".$_POST['reporting_time'][$i]."','".$_POST['automation'][$i]."','".$_POST['reviews'][$i]."','". $display_data['city'] ."','".$_POST['testcondition'][$i]."' )";
$sql .= ',';
}
}
$sql = rtrim($sql,', ');
$sql .= ' ON DUPLICATE KEY UPDATE sample_type=VALUES(sample_type) , price = VALUES(price) , discounted_price = VALUES(discounted_price) , dep_id = VALUES(dep_id) , reporting_time = VALUES(reporting_time) , automatic = VALUES(automatic) , remarks = VALUES(remarks) , city = VALUES(city) , testcondition = VALUES(testcondition) ';
echo '$sql$sql '.$sql;
if(!mysqli_query($conn,$sql)){
// echo mysqli_errno($conn);
if(mysqli_errno($conn) == 1062){
$_SESSION['message'] = '<div class="alert alert-danger">Some values needed to be unique. Please read instructions carefully.</div>';
}
}
else{
if(mysqli_affected_rows($conn) == 1){
$conn->close();
$_SESSION['message'] = '<div class="alert alert-success">Data inserted. And data that already exists has been updated. </div>';
echo $_SESSION['message'];
//echo '<script type="text/javascript">window.location = "add-test-menu.php"</script>';
}
else{
//error
$_SESSION['message'] = '<div class="alert alert-danger">Data inserted. And data that already exists has been updated. </div>';
echo $_SESSION['message'];
}
//echo '<script>window.location = "add-test-menu.php";</script>';
}
}
?>

答案 0 :(得分：0)
您在表单中遗漏了action属性。
你的表格标签应该是这样的
<form method="POST" action="yourTargetFile.php">
你正在为单个值传递数组。
见这里
<input type="hidden" name="test_name[]" value="<?php echo $d['id']; ?>">
和
<select name="testcondition[]" class="form-control">
如果您没有多个值，为什么要尝试传递数组？ 你需要像这样传递。并改变所有不是多个值的字段。
<input type="hidden" name="test_name" value="<?php echo $d['id']; ?>">
插入没有for和foreach循环的数据。
