使用Jquery POST一个数组

Question

I am trying to UPLOAD multiple file using Post jQuery method but I get an error of undefined index when trying to view the array result. Tried to search the answers but still unable to do it. What is the correct way to do this. Below are the example of my codes,

HTML

<input type="file" name="others[]" multiple="multiple">

jQuery

$(document).ready(function(){   
 $("#submit").click(function(){
    var array = [$("input[name='others']").val()],
        others = {
            "upload[]": array,
        },
        id =  $("input[name='id']").val();
    $.post('updated-file-others.php',
    {
        others : others,
        id : id 
    }, function(data){
        $("#result_post").html(data); 
    });  
 });
});

PHP

if(isset($_POST['id'])){
  $id = $_POST['id'];
  $others = array($_FILES['upload']['name']);
}
echo "<pre>"; print_r($others); echo "</pre>";  

Answer 1

A couple of things

• $("input[name='others']") doesnt match others[] in your HTML. Why dont you use an id and match it?
• You might need to ensure that you have enctype="multipart/form-data" inside your form.
• whats the output of $("input[name='id']").val(); You have not provided any clue in your code.
