PHP处理包含随机项目的清单

Question

I have a HTML Table which is used as a checklist. There are multiple checklists and user can create their own checklist and items as well. This checklist have a random amount of rows.

$table .= "<tr style='cursor: pointer; border: 1px solid black;' onclick='selectVal(this)'>
                          <td style='border: 1px solid transparent; width: 5%;' class='cbTrue'><input type='hidden' value='".$srcarr['id']."' name='item_id' /><input type='checkbox' name='".$srcarr['id']."_True' /></td>
                          <td style='border: 1px solid transparent; width: 30%;'>".$srcarr['item']."</td>
                          <td style='border: 1px solid transparent; width: 30%;'><input type='hidden' class='ckTimeStamp' /></td>
                     </tr>";

$srcarr is my array which comes from a MySQLI query and contains the information of the ID of an Item or the Name oft an Item.

My problem is: I want to save the items with the information if they have been checked and at which time in a MySQL Database. But I have no idea how to know after the form have been posted to PHP how I can separate the information about the single items. Does anybody have an idea?

Answer 1

Did you mean the exact time when user click the checkbox not the moment when they submit the pages?

If it is the exact moment they check your checkbox you could use javascript to assign the time value on hidden input by adding it on event change at checkbox element.

on jquery it will be like:

$('input[type="checkbox"][name="checkbox-name"]').change(function() {
    if(this.checked) {
        var now = new Date;
        $('input. ckTimeStamp').val(now.getTime);
    }
});

Answer 2

As I understood, you have some rows to add and you need to create a unique name for each input.

Try this:

<input type='hidden' value='".$srcarr['id']."' name='item_id[".$srcarr['id']."]' /><input type='checkbox' name='".$srcarr['id']."_True' />

Then in the form processing, loop through $_POST['item_id'] and from keys of the array check if is set $_POST[$key . '_TRUE'] $_POST[$key . '_TRUE']

See Processing HTML checkbox forms with PHP for code example.

What you need is to have a list of checkbox with the same name like custom_checkboxes[] and store $srcarr['id'] as a value. In PHP, when you receive the data as an array, only those $srcarr['id'] that was checked will be included inside the array.
