表单数组的隐藏元素未在PHP中设置

Question

So I've been tasked with crawling through a smallish PHP application to fix bugs and improve things where I can. One thing I noticed was that updates were not updates, they were deletes+inserts, so I'm doing what I can to remedy that.

To that end, I've added a hidden element to each row of a large table of items which will contain the id of said item so that I know what to update. Problem is that it isn't getting set in the items array in $_POST , and I haven't any clue why.

As an example, here's a row in HTML:

<div class="row">
  <div class="c item_index"><sub>1</sub></div>
  <input type="hidden" name="ordered_items[1][id]" id="item_id1" value="9" disabled="">
  <div class="c qty">
    <input type="text" name="ordered_items[1][quantity]" id="quantity1" value="12">
  </div>
  <div class="c vendor_num">
    <input type="text" name="ordered_items[1][vendor_number]" id="vendor_num1" value="">
  </div>
  <div class="c item_desc">
    <input type="text" name="ordered_items[1][description]" id="desc1" value="12">
  </div>
  <div class="c cost_per">
    <input type="text" name="ordered_items[1][cost_per]" id="cost1" value="12.00">
  </div>
  <div class="c total">
    <input type="text" name="ordered_items[1][total]" class="total" placeholder="0.00"
           id="total1" value="144.00" readonly="">
  </div>
</div>

Here's it's entry in $_POST :

[ordered_items] => Array
        (
            [1] => Array
                (
                    [quantity] => 12
                    [vendor_number] => 
                    [description] => 12
                    [cost_per] => 12.00
                    [total] => 144.00
                )

        )

I appreciate any and all suggestions!

Answer 1

Remove the disabled="" attribute. Disabled inputs are not submitted when posting.

From the HTML specification

A number of attributes are boolean attributes. The presence of a boolean attribute on an element represents the true value, and the absence of the attribute represents the false value.

If the attribute is present, its value must either be the empty string or a value that is an ASCII case-insensitive match for the attribute's canonical name, with no leading or trailing whitespace.

Note : The values "true" and "false" are not allowed on boolean attributes. To represent a false value, the attribute has to be omitted altogether.

尝试删除隐藏字段中的disabled=""属性。
