我目前无法发布尚未检查过的复选框，需要您的帮助。以下是我目前使用的代码。
PHP
while($select_info2 = mysqli_fetch_assoc($select_info1)){
$n='1';
echo "<tr>";
echo "<td>".$select_info2['Device_DNS_name']."</td>";
echo "<td>".$select_info2['Uplink_port']."</td>";
echo "<td>".$select_info2['VLAN']."</td>";
echo "<td>".$select_info2['Teamed_network']."</td>";
echo "<td>".$select_info2['Teamed_description']."</td>";
for($a = $select_detailed_dns2['starting_port']; $a <= $select_detailed_dns2['ending_port']; $a++ ){
if('10' > $a){
if ($select_info2["port-0".$a] == "1" || $select_info2["port-0".$a] == "01" ){
$check ='checked="checked"';
}else{
$check = '';
}
?>
<td><input type="checkbox" name="check_<?php echo $select_info2['ID']."[]"?>" id="check_<?php echo $select_info2['ID']?>" <?php echo $check ?> value = "On" /></td>
<?php
}else{
if ($select_info2["port-".$a] == "1" || $select_info2["port-".$a] == "1" ){
$check ='checked="checked"';
}else{
$check = '';
}
?>
<td><input type="checkbox" name="check_<?php echo $select_info2['ID']."[]"?>" id="check_<?php echo $select_info2['ID']?>" <?php echo $check ?> value = "On" /></td>
<?php
}
}
?>
<td><input type="button" name="Check_All" value="Check All" onClick="CheckAll(document.checktable.check_<?php echo $select_info2['ID']?>)"> </td>
<td><input type="button" name="Un_Check_All" value="Uncheck All" onClick="UnCheckAll(document.checktable.check_<?php echo $select_info2['ID']?>)"> </td>
<td><input type="submit" name="update_row" value="Update Row" > </td>
<?php
echo "</tr>";
}
上面的代码生成复选框，具体取决于数据库中表中有多少列。您可能会问为什么名称是数组格式。这样我就可以发布所有值。您可能也会问为什么id是相同的而不是不同的。这样我就可以定位整行来检查或取消选中。以下是我目前输出所有选中复选框的方式：
<?php
if(isset($_POST['update_row'])){
$c1 = $_POST['check_1'];
var_dump($c1);
}

希望你能帮忙 谢谢
答案 0 :(得分：0)
你能不设置default =“0”或“2”或其他东西并检查它？
也许这有助于... Post the checkboxes that are unchecked
