如何从PHP / AJAX / jQuery中的表单外的JavaScript变量中保存数据?

PHP newbie here. I want to save a variable (from jQuery) in PHP/MySQL, but this variable is outside the form. The values from the form elements inside the form is being saved fine though. The variable name in this case is 'mode', and I want the 'mode' to be sent to PHP.

Here's code :

HTML form;

<form action="submit.php" method="post" id="myform">
 <textarea id="source1" name="source1"></textarea>
<textarea id="source2" name="source2"></textarea>
 <input type="image" src="images/save.png" name="submit" id="submit" title="Save"  class="save-button"/>    

jQuery / AJAX:

mode = 1;  // This value needs to be stored/saved

// AJAX form save
$("form#myform").submit( function () {    


$submit_time = date('Y/m/d H:i:s');
$content1 = $_POST['source1'];
$content2 = $_POST['source2'];
$mode = $_POST['mode'];  // This value needs to be stored/saved

Is the solution to create a hidden form field inside the form?

PHP新手在这里。 我想在PHP / MySQL中保存一个变量(来自jQuery),但是这个变量在表单之外。 表单中的表单元素的值虽然保存得很好。 在这种情况下,变量名称是'mode',我希望'mode'被发送到PHP。


HTML form;

 &lt; form action =“submit.php”method =“post”id =“myform”&gt; 
&lt; textarea id =“source1”name =  “source1”&gt;&lt; / textarea&gt; 
&lt; textarea id =“source2”name =“source2”&gt;&lt; / textarea&gt; 
&lt; input type =“image”src =“images / save.png”  name =“submit”id =“submit”title =“Save”class =“save-button”/&gt;  
&lt; / form&gt; 

jQuery / AJAX:

  mode = 1;  //需要存储/保存此值
 // AJAX格式save 
 $ .post(
'submit.php',  \ N $(本).serialize(),
 .... \ N} 

PHP:< / p>

  $ submit_time = date('Y / m / d H:i:s'); 
 $ content1 = $ _POST ['source1']; 
 $ content2 =  $ _POST ['source2']; 
 $ mode = $ _POST ['mode']; //需要存储/保存此值

是 在表单中创建隐藏表单字段的解决方案?

    If the variable is not inside the form it doesn't get send to the server.

    The solution is to put the variable into hidden field inside the form
