建立一个足球预测网站。我正在从 DBMS 的固定装置表中获取主队名称和客队名称，每个固定装置都有相应的下拉框，以便用户可以预测比分。我无法让它工作。感谢您的帮助!
//establish connection
<?php
$connection = mysql_connect('localhost', 'root', 'password');
mysql_select_db('mls');
$query = "SELECT * FROM fixtures WHERE Fixture_ID BETWEEN '1' and '10' ";
$result = mysql_query($query);
$num = mysql_num_rows($result);
if($num>0){
echo"<table>";
echo "<th>Home Team</th>";
echo "<th>Home Score</th>";
echo "<th>Away Score</th>";
echo "<th>Away Team</th>";
for($count=0;$count<$num; $count++){
$row = mysql_fetch_array($result);
echo"<tr>
<td>".$row['Home_Team']."</td>
<td>
<form id="myForm" method="post" action="process3.php">
<select name="Home_Score">
<select id='H".$count."'>
<option value="0">0</option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
</select >
</td>
<td>
<form id="myForm" method="post" action="process3.php">
<select name="Home_Score">
<select id='A".$count."'>
<option value="0">0</option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
</select>
</td>
<td>".$row['Away_Team']."</td>
</tr>";
}
echo"</table>";
<input type="submit" title="Submit the form">
</form>
}
?>
<html>
<?php
//process3.php file
<?php
include_once('db.php');
$Home_Score = $_POST['Home_Score'];
$Away_Score = $_POST['Away_Score'];
if(mysql_query("INSERT INTO user_prediction VALUES('$Home_Score', '$Away_Score')")){
$result = "Successfully Inserted";
else
$result = "Insert failed";
?>
//myscript.js file
?>
$("#sub").click(function(){
$.post( $("#myForm).attr("action"), $("#myForm:input").serializeArray(),
function (info){$("#result").html(info);});
});
$("#myForm").submit(function(){
return false;
});
最佳答案
虽然有很多事情可能会导致问题，但请注意:
<select name="Away_Score">
//count id for unique values in dropdown
<select id='A".$count."'>
$count 在此处将按字面意思表示为字符串“$count”，因为此代码未包含在 PHP 标记中。尝试将与此类似的代码实例更正为如下内容:
<?php
echo '<select name="Away_Score">';
//count id for unique values in dropdown
echo '<select id="A' . $count . '">';
?>
关于javascript - PHP 新手在将下拉值发布到 MySQL 数据库时遇到问题。我的表格格式也关闭了。任何人都可以对此有所了解吗？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/31046437/
