在这里，我已经创建了数据库，现在我想将以下字段的值保存到数据库中，但是它给出了未定义的索引。我该怎么办。
if(!empty($_POST['Sourcing_HR'] AND $_POST['DOS'] AND $_POST['Candidate_Name'] AND $_POST['Candidate_Name'] AND $_POST['Total_Experience'] AND $_POST['Current_CTC'] AND $_POST['Expected_CTC'] AND $_POST['Current_Location'] AND $_POST['Preferred_Location'])){
$sql = "INSERT INTO candidatesListFields (Sourcing_HR, DOS, Candidate_Name, Total_Experience, Current_CTC, Expected_CTC, Current_Location, Preferred_Location) VALUES ('$Sourcing_HR', '$DOS', '$Candidate_Name', '$Total_Experience', '$Current_CTC', '$Expected_CTC','$Current_Location','$Preferred_Location')";
echo($_POST[$Sourcing_HR.' '. $DOS.' '. $Candidate_Name.' '. $Total_Experience.' '. $Current_CTC.' '. $Expected_CTC.' '. $Current_Location.' '. $Preferred_Location]);
}
if (isset($_POST['Sourcing_HR'])) {
$Sourcing_HR = $_POST['Sourcing_HR'];
}
?>
这无法正常工作，如果有人在那里请帮助*

empty()不接受多个参数，即使接受了（如isset()这样），它也希望它们之间用逗号分隔（而不是AND）。
您可以像这样在单个调用中检查POST是否存在所有预期的isset()键：
if (isset($_POST['Sourcing_HR'], $_POST['DOS'], $_POST['Candidate_Name'],
$_POST['Candidate_Name'], $_POST['Total_Experience'], $_POST['Current_CTC'],
$_POST['Expected_CTC'], $_POST['Current_Location'], $_POST['Preferred_Location'])) {
或者，如果需要，请使用!empty()确保所有值都不为空并且不包含字符串0。但是!empty()必须在每个元素上调用。
if (!empty($_POST['Sourcing_HR']) && !empty($_POST['DOS']) && !empty($_POST['Candidate_Name'])
&& !empty($_POST['Candidate_Name']) && !empty($_POST['Total_Experience'])
&& !empty($_POST['Current_CTC']) && !empty($_POST['Expected_CTC'])
&& !empty($_POST['Current_Location']) && !empty($_POST['Preferred_Location'])) {
如果您希望针对不包含所需数据的特定字段提供个性化反馈，则必须将if条件（需要编写的代码更多）分开。
在检查所有期望的元素都存在之后，请使用带占位符和绑定参数的预准备语句以确保安全性和稳定性（而不是mysqli逃逸）。
这是使用面向对象语法的未经测试的建议：
if (!$conn = new mysqli("localhost", "root", "", "candidatesList")) {
echo "Database Connection Error: " , $conn->connect_error; // don't show exact error publicly
} else {
if (!$stmt = $conn->prepare("INSERT INTO candidatesListFields (Sourcing_HR, DOS, Candidate_Name, Total_Experience, Current_CTC, Expected_CTC, Current_Location, Preferred_Location) VALUES (?,?,?,?,?,?,?,?)")) {
echo "Prepare Syntax Error: " , $conn->error; // don't show exact error publicly
} else {
if (!$stmt->bind_param("ssssssss", $_POST['Sourcing_HR'], $_POST['DOS'], $_POST['Candidate_Name'], $_POST['Total_Experience'], $_POST['Current_CTC'], $_POST['Expected_CTC'], $_POST['Current_Location'], $_POST['Preferred_Location']) || !$stmt->execute()) {
echo "Query Error: " , $stmt->error; // don't show exact error publicly
}else{
echo "Success";
}
$stmt->close();
}
$conn->close();
}

U应该使用&& !empty($_POST['DOS'])而不是,
