Hello I have a problem with my php code.. there are 3 tables for a recruitment system.
CREATE TABLE IF NOT EXISTS `members` (
`uid` int(11) NOT NULL AUTO_INCREMENT,
`username` varchar(25) CHARACTER SET utf8 COLLATE utf8_bin NOT NULL,
`password` varchar(25) CHARACTER SET utf8 COLLATE utf8_bin NOT NULL,
`cpassword` varchar(25) CHARACTER SET utf8 COLLATE utf8_bin NOT NULL,
`email` varchar(30) CHARACTER SET utf8 COLLATE utf8_bin NOT NULL,
`role` varchar(30) CHARACTER SET utf8 COLLATE utf8_bin NOT NULL,
PRIMARY KEY (`uid`)'
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=60 ;
The candidate table :
CREATE TABLE IF NOT EXISTS `candidate` (
`fullname` varchar(35) CHARACTER SET utf8 COLLATE utf8_bin NOT NULL,
`webpage` varchar(150) CHARACTER SET utf8 COLLATE utf8_bin NOT NULL,
`tel` int(35) NOT NULL,
`nationality` varchar(35) CHARACTER SET utf8 COLLATE utf8_bin NOT NULL,
`position` varchar(30) CHARACTER SET utf8 COLLATE utf8_bin NOT NULL,
`interviewed` varchar(30) NOT NULL DEFAULT 'No',
`rating` varchar(30) NOT NULL,
`c_id` int(11) NOT NULL AUTO_INCREMENT,
`uid` int(11) NOT NULL,
PRIMARY KEY (`c_id`),
KEY `uid` (`uid`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=135 ;
The academic table :
CREATE TABLE IF NOT EXISTS `academic_candidate` (
`degree` varchar(30) CHARACTER SET utf8 COLLATE utf8_bin NOT NULL,
`exp_years` varchar(25) CHARACTER SET utf8 COLLATE utf8_bin NOT NULL,
`comment1` varchar(300) CHARACTER SET utf8 COLLATE utf8_bin NOT NULL,
`proposed_positions` varchar(25) CHARACTER SET utf8 COLLATE utf8_bin NOT NULL,
`research_years` varchar(25) CHARACTER SET utf8 COLLATE utf8_bin NOT NULL,
`comment2` varchar(300) CHARACTER SET utf8 COLLATE utf8_bin NOT NULL,
`department` varchar(25) CHARACTER SET utf8 COLLATE utf8_bin NOT NULL,
`a_id` int(25) NOT NULL AUTO_INCREMENT,
`uid` int(11) NOT NULL,
`c_id` int(11) NOT NULL,
PRIMARY KEY (`a_id`),
UNIQUE KEY `id` (`a_id`),
KEY `uid` (`uid`),
KEY `c_d` (`c_id`),
KEY `c_id` (`c_id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=40 ;`
academic_candidate
ALTER TABLE
academic_candidate ADD CONSTRAINT
academic_candidate_ibfk_1 FOREIGN KEY (
uid ) REFERENCES
members (
uid ) ON DELETE CASCADE ON UPDATE CASCADE, ADD CONSTRAINT
academic_candidate_ibfk_2 FOREIGN KEY (
c_id ) REFERENCES
candidate (
c_id ) ON DELETE CASCADE ON UPDATE CASCADE;
--
candidate
ALTER TABLE
candidate ADD CONSTRAINT
candidate_ibfk_1 FOREIGN KEY (
uid ) REFERENCES
members (
uid ) ON DELETE CASCADE ON UPDATE CASCADE;
--
Now, I use this query in order to store the values in the table academic_candidate
session_start();
$query = "SELECT * FROM academic_candidate WHERE degree = '$degree'";
$result = mysql_query($query);
$count = mysql_num_rows($result);
if($count > 0){
echo "You ALready complete the form </br>";
header("Location:../candidate/candidate_index.php");
}
else{
$degree =($_POST['degree']);
$exp_years = ($_POST['exp_years']);
$comment1 = ($_POST['comment1']);
$proposed_positions = ($_POST['proposed_positions']);
$research_years=($_POST['research_years']);
$comment2=($_POST['comment2']);
$department=($_POST['department']);
$uid=($_SESSION['uid']);
$query1 = "INSERT INTO academic_candidate
(degree,exp_years,comment1,proposed_positions,research_years,comment2,department,uid,c_id)
SELECT
'$degree','$exp_years','$comment1','$proposed_positions','$research_years','$comment2','$department','$uid','$c_id'
FROM candidate
WHERE uid='$uid' AND c_id='$c_id' ";
$result = mysql_query($query1);
if(!$result){
echo "Error";
die (mysql_error());
}
else{
header("Location:../candidate/view_application.php");
}
}
My problem is that stores all the values on the table academic_candidate table but the c_id is 0 . What can I do in order to take the candidate.c_id?
You're passing literal values to your INSERT INTO
statement.
Consider the difference:
SELECT 'bar' FROM foo;
SELECT bar FROM foo;
Looking at your query:
SELECT '$degree'
Is not the same as:
SELECT degree
One of these is simply echoing whatever value you pass in, the other is actually selecting a column from the DB.
