How to receive a batch of checkbox data in PHP?
The key code is:
while ($row= mysql_fetch_array($result, MYSQL_ASSOC))
{ $id=$row[id];
$html=<<<html
<tr><td>
<input style="float:left" type="checkbox" name="mycheckbox[]" value="$id">
<span style="float:left">$row[content]</span>
<span style="col开发者_如何学Goor:black;float:right">$row[submitter]</span></td></tr>
html;
echo $html;
}
There are many checkboxes.
How to receive these checkbox values in another PHP file?
You know, you need to name these checkboxes so a PHP file can receive these values on the other side. But how to name these checkboxes? If I name 1,2, 3,...,how can I associate them with $row[id]?
You need to give them names - you can either do it like this:
<input style="float:left" type="checkbox" id="$id" name="$id" value="true">
or like this to get an array:
<input style="float:left" type="checkbox" id="$id" name="myBoxes[$id]" value="true">
You can then check isset($_POST[$id]) or isset($_POST['myBoxes'][$id])
Name your checkboxes so you can easily identify them. eg
$CheckBoxHTML = "<input type='checkbox' name='check_$row[id]' value='YES'>Check This";
then in your recieving php file you can find all checkboxes by
foreach ($_POST as $key => $value)
{
if (strpos($key,'check_') !== false)
{
list($tmp, $ID) = split('_', $key);
$CheckedValues[] = $ID;
}
}
That will pull out all your checked ids.
