我创建了一个简短的问题表单，我想在选中单选按钮时插入输入文本的值。目前我只能插入单选按钮的值，不能插入输入文本的值。 我该怎么做？

PHP 代码:-
<?php
session_start();
require_once 'dbConn.php';
if(!empty($_POST{'submit'})) {
$questiontext = $_POST['questiontext'];
$anstext1 = $_POST['ans1'];
$anstext2 = $_POST['ans2'];
$anstext3 = $_POST['ans3'];
$anstext4 = $_POST['ans4'];
if(empty($questiontext) && empty($anstext1) && empty($anstext2) && empty($anstext3) && empty($anstext4)) {
echo "Please enter data";
echo "<script>setTimeout(\"location.href = 'admin_mcqform.php';\",2000);</script>";
return false;
}
if(!isset($_POST['radioans']))
{
echo "Please enter data";
echo "<script>setTimeout(\"location.href = 'admin_mcqform.php';\",2000);</script>";
return false;
}
$radiobtn = $_POST['radioans'];
try {
//add the first record into question table
$stmt1 = $conn->prepare("INSERT INTO `question`(question_text, question_type) VALUES(:questiontext, 'shortquestion')");
$stmt1->bindParam(":questiontext",$questiontext);
$stmt1->execute();
//add the last id insert for question into option tbl question_id
$questionID = $conn->lastInsertId();
$answerID = $conn->lastInsertId();
//add second record into option_tbl
$stmt2 = $conn->prepare("INSERT INTO `option_tbl`(option_answer,question_id) VALUES(:ans,$questionID)");
$stmt2->bindParam(":ans",$anstext1);
$stmt2->execute();
$stmt2->bindParam(":ans",$anstext2);
$stmt2->execute();
$stmt2->bindParam(":ans",$anstext3);

$stmt2->bindParam(":ans",$anstext4);
$stmt2->execute();
//add third record into answer table

最佳答案
它可以通过使用一点 java 脚本来实现。或者你可以使用 J查询(代码行会少)。我在这里使用 java 脚本...
<!-- The id of input type=text and Value of radio must be the same for each items/rows-->
<form id="myForm" action="admin_shortquestform.php" method="POST">
1.<input type="text" size="20" name="ans2" id="1"><input type="radio" name="radioans" value="1"/><br>
2.<input type="text" size="20" name="ans3" id="2"><input type="radio" name="radioans" value="2" /><br>
3.<input type="text" size="20" name="ans4" id= "3" ><input type="radio" name="radioans" value="3" /><br>
<!-- selected ans is set to the below hidden input field in js function, and you can get it in php by using $_POST['selected_ans'] -->
<input type="hidden" name="selected_ans" id="hidden_input" />
<input type="button" onclick="myFunction()" value="Submit">
</form>
<script>
function myFunction() {
var radios = document.getElementsByName('radioans');
for (var i = 0, length = radios.length; i < length; i++) {
if (radios[i].checked) {
var selected_radio_value=radios[i].value;
var selected_text_input=document.getElementById(selected_radio_value);
var selected_text_input_value=selected_text_input.value;//selected textbox value
var input_hidden=document.getElementById("hidden_input");
input_hidden.value=selected_text_input_value+"";// setting selected textbox value to hidden input field
document.getElementById("myForm").submit();// submitting the form
break;
}
}
}
</script>
并且在您的表单操作 php 文件 (admin_shortquestform.php) 中:-
使用 if($_SERVER['REQUEST_METHOD'] === 'POST') 而不是 if(!empty($_POST{'submit'}))
您可以通过编写以下代码来获取选择的ans
$selected_answer=$_POST['selected_ans'];
