大家好,我有一个联系表和验证码在那里。我希望在提交表格后检查检查。我发布了文本框值,它显示正确,但复选框不起作用。这是我的代码。

<input type="checkbox" name="txtCheck" value="<?php echo $_POST['txtCheck'];?>" /><br />
<label>Name</label><br />
<input type="text" name="txtName" id="NameTextBox" value="<?php echo $_POST['txtName']; ?>" />
<br />
<label>E Mail</label><br />
<input type="text" name="txtEmail" id="EmailTextBox" value="<?php echo $_POST['txtEmail'];?>" />
<input name="BtnSubmit" type="submit" onclick="MM_validateForm('NameTextBox','','R','EmailTextBox','','R');return document.MM_returnValue" value="Send" />
</form>

提交表单后如何保留复选框。?
