我正在使用bootstrap库测试我在php中的技能,并且我处于死路。
我有两个表,students
和countries
。
我有一个选择框,我获得了国家(和相关的ID),我希望以一种形式看到该国家的学生。
实际上,我收到了表格,得到了选择,但我无法找到如何互动。
请帮帮我。感谢
我的php的代码
<?php
//Access to BDD
include 'database.php';
?>
<html>
<Head>
<title>List of students</title>
<script src="bootstrap/js/bootstrap.js"></script>
<link rel="stylesheet" href="bootstrap/css/bootstrap.css">
</Head>
<body>
<!-- formulaire de recherche -->
<form class="panel-group form-horizontal" method="get" action="home.php" role="form">
<div class="panel panel-default">
<div class="panel-body">
<div class="panel-header">
<h4>Search</h4>
</div>
<div class="col-sm-3">
<!-- dropdown countries -->
<select class="form-control" id="select" name="country">
<option value="">country</option>
<?php
$sel_country = "SELECT * FROM countries";
$run_country = mysqli_query($conn,$sel_country);
while ($rows= mysqli_fetch_assoc($run_country)){
echo '<option value='.$rows['id'].'>'.$rows['brand_name'].'</option>';
}
?>
</select>
<br/>
<br/>
<button type="submit" class="btn btn-default" id="searchbtn" name="submit">Go</button>
</div>
</div>
</div>
</form>
<?php
//SQL listing all the students.
$sql = "SELECT * FROM student ORDER by student_id"; //CHOIX NON PLUS!!!
$run_sql = mysqli_query($conn, $sql);
while ($rows = mysqli_fetch_assoc($run_sql)){
echo '<div class="container">
<table class="table table-hover">
<tr>
<td><h2><a class="btn btn-info" href="detail.php?vo_id='.$rows['student_id'].'">'.$rows ['name'].'</a></h2></td>
</tr>
<tr>
<td>'.$rows ['surname'].'</td>
</tr>
<tr>
<td>'.$rows ['age'].'</td>

<tr>

</div>

}?>
答案 0 :(得分:0)
更新现有代码中的以下代码: 假设所有代码都在同一页面上(home.php)
if(isset($_GET[country]))
{
$sql = "SELECT * FROM student WHERE country_id =". $_GET["country"]." ORDER by student_id"; //CHOIX NON PLUS!!!
$run_sql = mysqli_query($conn, $sql);
while ($rows = mysqli_fetch_assoc($run_sql)){
echo '<div class="container">
<table class="table table-hover">
<tr>
<td><h2><a class="btn btn-info" href="detail.php?vo_id='.$rows['student_id'].'">'.$rows ['name'].'</a></h2></td>
</tr>
<tr>
<td>'.$rows ['surname'].'</td>
</tr>
<tr>
<td>'.$rows ['age'].'</td>
</tr>
<tr>
<td>'.$rows ['country'].'</td>
</tr>
</table>
</div>
<br>';
