[英]How to validate radio buttons using php and mysql?
I have this set of code for radio buttons and it selects all the three options instead of one at a time. 我为单选按钮设置了这组代码,它选择了所有三个选项,而不是一次选择一个。 And how to connect it to MySQL database for proceeding further with the selected option on the radio button. 以及如何将其连接到MySQL数据库以进一步处理单选按钮上的选定选项。 Thanks in advance :) 提前致谢 :)
<div class="radio" method="post" action="quiz.php">
<label><input type="radio" name="GK" value="GK">GK</label><br><br>
<label><input type="radio" name="OP" value="OP">Our Pasts</label><br><br>
<label><input type="radio" name="D" value="D">Discovery</label><br><br><br>
<button type="submit" class="btn btn-primary">Submit</button>
You have to use the same Name for the Radio options. 您必须对Radio选项使用相同的Name。
Also the button needs a name and a value: 此外,按钮还需要一个名称和一个值:
<form class="radio" method="post" action="quiz.php">
<label><input type="radio" name="RADIO" value="GK">GK</label><br><br>
<label><input type="radio" name="RADIO" value="OP">Our Pasts</label><br><br>
<label><input type="radio" name="RADIO" value="D">Discovery</label><br><br><br>
<button name="SubmitForm" type="submit" value='save' class="btn btn-primary">Submit</button>
</form>
After that you can $_POST the values: 之后,您可以$ _POST值:
$ButtonSaved = $_POST["SubmitForm"];
$RadioValue = $_POST["RADIO"];
if($ButtonSaved == "save")
{
//do stuff with database
}

EDIT: as mentioned in the comments your div should be an form 编辑:如评论中所述,您的div应该是表格
开始以表格形式而不是div形式放置,然后使用相同的名称命名按钮...就这样,如果您对quiz.php的理解正确的话...
You have different names for all radio buttons. 所有单选按钮的名称都不同。 Set one name for all radio buttons which belong to same group. 为属于同一组的所有单选按钮设置一个名称。
<label><input type="radio" name="SomeName" value="GK">GK</label><br><br>
<label><input type="radio" name="SomeName" value="OP">Our Pasts</label><br><br>
<label><input type="radio" name="SomeName" value="D">Discovery</label><br><br><br>
<input type="submit" name='submit' class="btn btn-primary" value="Submit">
In php 在PHP中
<?php
if(isset($_POST['submit'])
$radioValue = $_POST['SomeName'];
?>
Since I can't comment, going with your question it seems that you can choose all 3 buttons instead one at a time? 既然我无法发表评论,那么您的问题似乎可以一次选择所有3个按钮,而不是一次选择一个? If that's the point then you should change your input type to: 如果那是重点,那么您应该将输入类型更改为:
<input type="checkbox" name="choices" value="GK" /><label for="GK">GK</label>
<input type="checkbox" name="choices" value="OP" /><label for="OP">Our Pasts</label>
<input type="checkbox" name="choices" value="D" /><label for="D">Discovery</label>
