[英]how can I select and display all the rows from the same user, underneath each other with php
[英]How I can display all rows in php
我寫了這段代碼來檢索數據庫中的一些行
session_start();
$con = mysqli_connect('localhost', 'root', '');
if(!$con)
{
die("not ok");
}
mysqli_select_db($con,"uoh");
$q = " SELECT * FROM student WHERE id = " . $_SESSION['user_id'] ." and password = " . $_SESSION['user_pass'];
$result = mysqli_query($con , $q ) ;
if($row = mysqli_fetch_array($result))
{
echo "this academic transcripts for " . $row["name"];
echo " and the id is " . $row["id"];
}
$q1 = " SELECT student_record.course,student_record.grade,student_record.term,coe_courses.crd
FROM student_record INNER JOIN coe_courses ON student_record.course_number = coe_courses.course_number
where student_record.id = ".$_SESSION['user_id'] ;
$result = mysqli_query($con , $q1 ) ;
if($row = mysqli_fetch_array($result))
{
echo "<br />";
echo "<table border=\"1\" style=\"width:500\">";
echo "<tr>";
echo "<th>coe_courses</th>";
echo "<th>terms</th>";
echo "<th>Grades</th>";
echo "<th>CRD</th>";
echo "</tr>";
echo "<tr>";
echo "<td>" . $row["course"]. "</td>";
echo "<td>" . $row["term"]. "</td>";
echo "<td>" . $row["grade"]. "</td>";
echo "<td>" . $row["crd"]. "</td>";
echo "</tr>";
echo "</table>";
}
問題是,當我在phpMyAdmin中有三行時,只顯示第一行。 在此處輸入圖片說明
您需要重復調用fetch_*
才能從結果集中檢索所有行; 每次調用它都會檢索結果集中的下一行。
在上面的示例代碼中,您將替換
if ($row = mysqli_fetch_array($result))
{
與
while ($row = mysqli_fetch_array($result))
{
這將一直循環直到fetch_array
嘗試讀取$result
的最后一條記錄以外的內容,此時fetch_array
返回false
並退出循環。
