Question

我有一个包含大约65个输入字段的HTML表单。该表单使用POST方法，并在提交时将字段定向到用于数据库输入的PHP脚本。没有科学。

但是，很少有POST个变量生成undefined index警告，并且在相应的数据库列中具有空值。我似乎无法弄清楚为什么很少有变量产生未定义的索引警告而其余的工作正常。

例如，以下是使用POST变量检索值的html和php脚本。 cfrom生成undefined index警告，cjnb工作正常。 HTML：

      <div class="col-5">
    <label>
      Current Job Nature of Business
      <input placeholder="" id="cjnb" name="cjnb" tabindex="27">
    </label>
  </div>
    <div class="col-5">
    <label>
      Joining Date
      <input placeholder="YYYY-MM-DD" id="cfrom" name="cfrom" tabindex="28" >
    </label>
  </div>

PHP：

$cjnb=$_POST['cjnb'];
$cfrom=$_POST['cfrom'];

我尝试使用isset并将变量设置为空值可能是因为它在$_POST['cfrom']中找不到值，但是，我在cfrom输入值中输入了值

请帮助！

Answer 1

无法看到当前提供的代码存在任何问题。

建议是在提交按钮上添加name="mySubmitButton"并添加type="submit"属性。

然后PHP将是：

if (isset($_POST['mySubmitButton'])) {

    // All the posted value
    $cfrom = htmlentities($_POST['cfrom']); // Escape your post values

}

Answer 2

首先检查开发者工具的网络标签中的请求，如果上面提到的字段不存在，那就意味着你的html中有拼写错误。

Answer 3

尝试使用print_r（$ _ POST）打印所有帖子值;在你的save.php脚本之上。

我尝试了相同的表单，我得到了你上面提到的值（$ _POST ['cfrom']）。

如果您在打印发布数据时也获得了值，那么您可能在代码下面做错了。

Answer 4

当您获得未定义的索引时，通常意味着您的表单输入名称与$ _POST索引不匹配，建议是记录变量并查看您获得的内容：

error_log('**********************DEBUG************************');
ob_start();
var_dump($_POST);
$postBack = ob_get_contents();
ob_end_clean();
error_log($postBack);
error_log('**********************DEBUG************************');

然后从日志中复制粘贴以创建验证：

if(isset($_POST['ccompany'],$_POST['cdesig'],$_POST['cjnb'],$_POST['cfrom'],$_POST['rnp'],$_POST['lcompany'],$_POST['ld'],$_POST['lnjb'])){
    $ccompany=$_POST['ccompany'];
    $cdesig=$_POST['cdesig'];
    $cjnb=$_POST['cjnb'];
    $cfrom=$_POST['cfrom'];
    $rnp=$_POST['rnp'];
    $lcompany=$_POST['lcompany'];
    $ld=$_POST['ld'];
    $lnjb=$_POST['lnjb'];
}else{
    echo "missing variable check log";
}

缺少$ _POST变量中的值
