Question

I have following table:

<form action="update-table.php" method="post">
<table class="table-data" border="1">
    <thead>
        <tr>
            <td>ID</td>
            <td>Live</td>
            <td>User</td>
            <td>Last Update</td>
            <td>Title</td>
            <td>Content</td>
            <td>Edit</td>
            <td>Delete</td>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td><input name="id[]" type="text" readonly="readonly" value="1" /></td>
            <td><input name="live[]" type="checkbox" checked="checked" value="1"/></td>
            <td>[e-mail]</td>
            <td>August 18, 2011, 10:10 am</td>
            <td>Title1</td>
            <td>Content1</td>
            <td><a href="edit-news.php?editID=1">Edit</a></td>
            <td><a href="delete-news.php?deleteID=1">Delete</a></td>
        </tr>
        <tr>
            <td><input name="id[]" type="text" readonly="readonly" value="2" /></td>
            <td><input name="live[]" type="checkbox" /></td>
            <td>[e-mail]</td>
            <td>August 18, 2011, 10:11 am</td>
            <td>Title2</td>
            <td>Content2</td>
            <td><a href="edit-news.php?editID=2">Edit</a></td>
            <td><a href="delete-news.php?deleteID=2">Delete</a></td>
        </tr>
        <tr>
            <td><input name="id[]" type="text" readonly="readonly" value="3" /></td>
            <td><input name="live[]" type="checkbox"/></td>
            <td>[e-mail]</td>
            <td>August 18, 2011, 10:10 am</td>
            <td>Title3</td>
            <td>Content3</td>
            <td><a href="edit-news.php?editID=3">Edit</a></td>
            <td><a href="delete-news.php?deleteID=3">Delete</a></td>
        </tr>
    </tbody>
</table>
<input type="submit" />

What I’m trying to do is display the array send with $_POST.

The problem is when checkbox is not checked – nothing is being send.

How to check if the $_POST['live'] is set, and if not – set it’s value to 0?

The following code does not work. Why?

if (!isset($_POST['live'])) {
            $_POST['live'] = "0";
        }


        for ($i=0;$i<count($_POST['id']);$i++) {

          echo "<p>".$_POST['id'][$i]."</p>";
          echo "<p>".$_POST['live'][$i]."</p>";
          echo "<hr />";

        } 

Answer 1

Try this:

for ($i=0;$i<count($_POST['id']);$i++) {

    if(!isset($_POST['live'][$i])){
        $_POST['live'][$i] = "0";
    }

    echo "<p>".$_POST['id'][$i]."</p>";
    echo "<p>".$_POST['live'][$i]."</p>";
    echo "<hr />";
}
