运行此命令时，提交表单后，我将检查数据库，并且复选框的所有值（smalltube，largetube，wakeboard）都表示是，即使未选中也是如此。
知道为什么吗？
复选框应从此处获取是或否值
//add info here for the check boxes.
if(empty (trim ($_POST["smallTube"]))){
$smallTube= "no";
}else{
$smallTube = "yes";
}
//add info here for the check boxes.
if(empty (trim ($_POST["largeTube"]))){
$largeTube= "no";
}else{
$largeTube = "yes";
}
//add info here for the check boxes.
if(empty (trim ($_POST["wakeboard"]))){
$wakeboard= "no";
}else{
$wakeboard = "yes";
}
这里是完整页面代码。

答案 0 :(得分：1)
这是因为您在复选框之前使用了隐藏的输入，并检查它是否不为空。
尝试检查是否设置了输入名称。
<div class="form-group">
<input type="checkbox" name="smallTube" value="yes"/><label>Small Tube</label><br>
<span class="help-block"><?php echo $smallTube_err; ?></span>
</div>
<div class="form-group">
<input type="checkbox" name="largeTube" value="yes"><label>Large Tube</label><br>
<span class="help-block"><?php echo $largeTube_err; ?></span>
</div>
<div class="form-group">
<input type="checkbox" name="wakeboard" value="yes"><label>WakeBoard</label><br>
<span class="help-block"><?php echo $wakeboard_err; ?></span>
</div>
并且：
//add info here for the check boxes.
if ( !isset( $_POST[ "smallTube" ] ) ) {
$smallTube = "no";
} else {
$smallTube = "yes";
}
//add info here for the check boxes.
if ( !isset( $_POST[ "largeTube" ] ) ) {
$largeTube = "no";
} else {
$largeTube = "yes";
}
//add info here for the check boxes.
if ( !isset( $_POST[ "wakeboard" ] ) ) {
$wakeboard = "no";
} else {
$wakeboard = "yes";
}
