用两个按钮提交表格

Question

I have 2 buttons in HTML form. And both of them should submit the form. I would need to capture which button has been clicked so i can use it to perform different actions based on which button was clicked.

I am able to submit the form with both the buttons but how would i capture which button was clicked in the php file .

<INPUT  type="button" name="submit" class="button" class="element_2" value="firstbutton">
<INPUT  type="button" name="submit1" class="button" class="element_2" value="second button.. ">

i am using post method in Jquery to submit the form. How can i check which HTML button was clicked in server side php script

You could use a hidden element here, something like this:

<input type="hidden" id="submittedBy" name="submittedBy">

Your current .submit() handler using .serialize() and $.post() should work, just update the hidden field when clicking either button, for example:

$("form :submit").click(function() {
  $("#submittedBy").val(this.name);
});

Then in PHP just check that $_POST["submittedBy"] == "submit" or "submit1" to see which caused it.

The alternative is to have the click handler POST and add in the value between .serializeArray() and when $.param() is called, like this:

$("form :submit").click(function() {
  var data = $(this.form).serializeArray();
  data.push({ name: 'submittedBy', value: this.name });
  $.post("myPage.php", data, function(result) {
    //do something
  });
  return false; //prevent normal form submission, even with the .submit() handler
});
