我有以下代码，并且SELECT正常工作以提取表单数据，但是，UPDATE语句不起作用。任何关于可以纠正什么以使其发挥作用的建议将不胜感激。
<?php
include 'includes/config.php';
require_once('includes/auth.php');
if ( isset( $_GET['aj'] ) && $_GET['aj'] == '1' ) {
if ( isset( $_GET['ax']) && $_GET['ax'] == 'education_details' ) {
$sql =
<<<SQL
SELECT *
FROM education
WHERE id = '{$_GET['rid']}'
ORDER BY date_completed DESC
SQL;
$sql_result = mysql_query($sql) or die("Get education detail error: " . mysql_error());
while ( $row = mysql_fetch_assoc($sql_result) ) {
$education_info = array(
'member_id' => $row['member_id'],
'name' => $row['name'],
'degree' => $row['degree'],
);
}
echo json_encode($education_info);
}
exit;
}
if ( isset($_POST['aj']) && $_POST['aj'] == '1' ) {
if (isset( $_POST['ax']) && $_POST['ax'] == 'save' ) {
$sql=
<<<SQL
UPDATE education
SET name = '{$education_info['name']}',
degree = '{$education_info['degree']}'
WHERE id = '{$education_info['rid']}'
SQL;
}
// echo json_encode($education_info);
exit;
}
?>

答案 0 :(得分：0)
尝试设置error_reporting（E_ALL）并检查firebug中的错误......
更新引用了一个未定义的变量：
$education_info['name']}'
当时没有设置，你可能想要使用$ _POST ['name']或者其他东西
（您可能希望在查询中绑定参数，因为它也更容易）

您忘记发布RID = where id
<?php
include 'includes/config.php';
require_once('includes/auth.php');
if ( isset( $_GET['aj'] ) && $_GET['aj'] == '1' ) {
if ( isset( $_GET['ax']) && $_GET['ax'] == 'education_details' ) {
$sql =
<<<SQL
SELECT *
FROM education
WHERE id = '{$_GET['rid']}'
ORDER BY date_completed DESC
SQL;
$sql_result = mysql_query($sql) or die("Get education detail error: " . mysql_error());
while ( $row = mysql_fetch_assoc($sql_result) ) {
$education_info = array(
'id' => $row['id'],
'member_id' => $row['member_id'],
'name' => $row['name'],
'degree' => $row['degree'],
);
}
echo json_encode($education_info);
}
exit;
}
if ( isset($_POST['aj']) && $_POST['aj'] == '1' ) {
if (isset( $_POST['ax']) && $_POST['ax'] == 'save' ) {
$sql=
<<<SQL
UPDATE education
SET name = '{$_POST['name']}',
degree = '{$_POST['degree']}'
WHERE id = '{$_POST['rid']}'
SQL;
}
$sql_result = mysql_query($sql) or die("Get education update error: " . mysql_error());
// echo json_encode($education_info);
exit;
}
?>
