我这里有一个注册船员的页面，但我不知道什么似乎是问题。该查询在phpmyadmin中工作但在php页面中不起作用。 这是我的代码：
session_start();
require 'config.php';
if (@$_SESSION['username']) {
if (isset($_POST['first_name'])&&isset($_POST['middle_name'])&&isset($_POST['last_name'])&&isset($_POST['age'])&&isset($_POST['birth_date'])&&isset($_POST['birth_place'])&&isset($_POST['gender'])&&isset($_POST['martial_status'])&&isset($_POST['religion'])&&isset($_POST['nationality'])&&isset($_POST['email'])&&isset($_POST['address1'])&&isset($_POST['address2'])&&isset($_POST['course'])&&isset($_POST['school'])&&isset($_POST['remarks'])) {
$first_name = $_POST['first_name'];
$middle_name = $_POST['middle_name'];
$last_name = $_POST['last_name'];
$age = $_POST['age'];
$birth_date = $_POST['birth_date'];
$birth_place =$_POST['birth_place'];
$gender = $_POST['gender'];
$martial_status = $_POST['martial_status'];
$religion = $_POST['religion'];
$nationality = $_POST['nationality'];
$email = $_POST['email'];
$address1 = $_POST['address1'];
$address2 = $_POST['address2'];
$course = $_POST['course'];
$school = $_POST['school'];
$remarks = $_POST['remarks'];
$date_added = date('Y-m-d');
if (!empty($first_name)&&!empty($middle_name)&&!empty($last_name)&&!empty($age)&&!empty($birth_date)&&!empty($birth_place)&&!empty($gender)&&!empty($martial_status)&&!empty($religion)&&!empty($nationality)&&!empty($email)&&!empty($address1)&&!empty($course)&&!empty($school)) {

echo 'Crew Successfuly Send to "PENDING PAGE"';
}

就像萨蒂说你忘记插入查询一样
$conn->query($query); // PDO for new php7
mysql_query($query,$conn); // for old code but this is deprecated
//$conn is mysql_connect in config.php (it's may be in another variable up on your write)
答案 1 :(得分：0)
<?php if (!empty($first_name)&&!empty($middle_name)&&!empty($last_name)&&!empty($age)&&!empty($birth_date)&&!empty($birth_place)&&!empty($gender)&&!empty($martial_status)&&!empty($religion)&&!empty($nationality)&&!empty($email)&&!empty($address1)&&!empty($course)&&!empty($school)) {
$query = "INSERT INTO `crew_info` (first_name,middle_name,last_name,age,birth_date,birth_place,gender,martial_status,religion,nationality,email_address,address_1,address_2,course,school_graduated,remarks,date_added,crew_status)
VALUES ('$first_name','$middle_name','$last_name','$age','$birth_date','$birth_place','$gender','$martial_status','$religion','$nationality','$email','$address1','$address2','$course','$school','$remarks','$date_added','PENDING')";
// for mysqli code starts
mysqli_query($con, $query);
// for mysqli code ends where $con is connection variable
echo 'Crew Successfuly Send to "PENDING PAGE"';
}
?>
你必须触发查询才能插入数据库，我想你忘记了

在查询后添加此代码以执行它
if (mysqli_query($conn,$query)) {
echo 'Your request is sent to queue';
}
else {
echo 'Something went wrong';
}
答案 3 :(得分：0)
我认为你错过了两分 1.你的php和mysql之间的连接。 2.解雇查询。
尝试使用此代码段。
SELECT C.Nom, E.Caution, E.Kilometrage
FROM FACTURATION AS F
LEFT JOIN ENREGISTREMENT AS E ON F.Enregistrement=E.Numero
LEFT JOIN RESTITUTION AS R ON F.Restitution=R.Numero
LEFT JOIN RESERVATION AS X ON F.Numero=X.Facturation
LEFT JOIN CLIENT AS C ON X.Numero_Client=C.Numero
//与数据库的连接
$username = "your_name";
$password = "your_password";
$dbhost = "localhost";
$conn = mysql_connect($dbhost, $username, $password);
然后把
if(! $conn )
{
die('Could not connect: ' . mysql_error());
}
echo 'Connected successfully';
之后解雇您的查询
if (!empty($first_name)&&!empty($middle_name)&&!empty($last_name)&&!empty($age)&&!empty($birth_date)&&!empty($birth_place)&&!empty($gender)&&!empty($martial_status)&&!empty($religion)&&!empty($nationality)&&!empty($email)&&!empty($address1)&&!empty($course)&&!empty($school)) {
$query = "INSERT INTO `crew_info` (first_name,middle_name,last_name,age,birth_date,birth_place,gender,martial_status,religion,nationality,email_address,address_1,address_2,course,school_graduated,remarks,date_added,crew_status) VALUES ('$first_name','$middle_name','$last_name','$age','$birth_date','$birth_place','$gender','$martial_status','$religion','$nationality','$email','$address1','$address2','$course','$school','$remarks','$date_added','PENDING')";
使用后关闭连接
if (mysqli_query($conn,$query))
{
echo 'Crew Successfuly Send to "PENDING PAGE"';
}
else
{
echo 'Some Syntax is wrong';
}
}
else {
echo 'Some field is empty';
}

@prakash是最接近正确的... 但是，我认为，使用value =“”将您所有的输入都设置在html上，这样您就不必执行所有的if（！empty（）垃圾操作，以后再获取空白...
$username = "your_name";
$password = "your_password";
$dbhost = "localhost";
$dbname = "your_db";
// just good practice to specify the db, later you may have multiple on the same server..
// use mysqli as someone else above stated...
$conn = mysqli_connect($dbhost, $username, $password,$dbname);
if(!$conn){
die('Connect Error: ' . mysqli_connect_error());
//again.. mysqli.. not mysql
}
// dont kill yourself with manual entry errors for the query...
// move $_POST to a new variable and prep the array for a loop;
$data = $_POST;
// get rid of the submit variable
unset($data['submit']);
// assuming this db field is int not varchar
// and assuming birthdate field is DATE or varchar
$data['age'] = intval($data['age']);
$data['birthdate'] = date('Y-m-d',strtotime($date['birthdate']));
// would be easier to set default value NOW() for date_added column and DATETIME
// NOW() will set that field to the CURRENT_TIMESTAMP on every insert for you...
// but the way you have it, and assuming db field is DATE or varchar
$data['date_added'] = date('Y-m-d');
// Same for 'crew_status' .. field VARCHAR or ENUM... default value 'PENDING'
$data['crew_status'] = 'PENDING';
// make a string variable to fill with fields...
$fields = '';
// make a string variable to to fill with insert values....
$values = '';
// loop through $data, add each value followed by a comma to string
// no single quotes on integers where the db field is INT .... like age...
foreach($data as $key=>$val){
// this is looking for the value="" from when a user blanks an input field....
if($val == ''){
// handles blank user inputs.. db fields NOT set 'not null'..no quotes around NULL
$values .= 'NULL,';
// if the value is not blanked... look for strings and dates....
}elseif(!is_int($val)){
// real_escape_string will kill any characters that will error like ' or \
// and remove in sql injection risks .. single quotes on varchar db field vals
$values .="'".mysqli_real_escape_string($conn,$val)."',";
// if input is not blank and !is_int() must be INT...age
}else{
//no quotes on integers going into INT db fields....
$values .= $val.',';
}
// add the $key (field name) to the $fields same order as $values, comma after each
// backticks around field names...
$fields .= "`".$key."`,";
}
// we are dragging an extra comma on $fields and $values at the end of each string
// we will get them in the insert query string....splitting up the query to explain
$query = "INSERT INTO `crew_info`";
//substr off the comma $fields is dragging "," put it between ( and )
$query .= "(".substr($fields,0,-1).")";
//substr off the comma $values dragging "," put it between ( and )
$query .= " VALUES (".substr($values,0,-1).")";
//not split query might be confusing to read..query would look like...
//"INSERT INTO `crew_info`(".substr($fields,0,-1).") VALUES (".substr($values,0,-1).")"
//now insert
if(!mysqli_query($conn,$query)){
// if there is an error... let someone know!
die('ooops!...'.mysqli_error());
}else{
// if no error......
echo 'you just inserted data!!! id# = '. mysqli_insert_id($conn);
}
答案 5 :(得分：-1)
您的sql字符串中有错误。 INSERT INTO表 VALUES （..，..）;
$query = "INSERT INTO `crew_info` VALUES (first_name,middle_name,last_name,age,birth_date,birth_place,gender,martial_status,religion,nationality,email_address,address_1,address_2,course,school_graduated,remarks,date_added,crew_status) VALUES ('$first_name','$middle_name','$last_name','$age','$birth_date','$birth_place','$gender','$martial_status','$religion','$nationality','$email','$address1','$address2','$course','$school','$remarks','$date_added','PENDING')";
