First of all, I know MySQL is a depreciated language, but my supervisor insists I use it.
I have three tables in my database. They are : "students", "tutors", "match" . When I find a run the below query($query2) I am checking the make sure all the criteria in that query is perfectly matched.
When it is perfectly matched I want to insert the following into the match table:
"insert into match (tutor_id, student_id, school_id) values ('$tutor_id','$student_id','$school_id')";
The "match" table contains the columns:
match_id(auto incremented), tutor_id, student_id, school_id
Any help would be greatly appreciated.
if(mysql_query($query2)){
$check_availability = "select *
from tutors, students
where tutor_availability = '$student_availability'
AND (tutor_subject_1 = '$student_subject_1'
OR tutor_subject_1 = '$student_subject_2'
OR tutor_subject_2 = '$student_subject_2'
OR tutor_subject_2 = '$student_subject_1')";
$run_5 = mysql_query($check_availability);
if(mysql_num_rows($run_5)>0) {
echo "<script>alert('we have a match')</script>";
my_sql_query($query3) = "insert into match (tutor_id, student_id, school_id) values ('$tutor_id','$student_id','$school_id')";
mysql_query($query3);
} else{
echo "<script>alert('no match found')</script>";
}
}
I think this line is wrong:
my_sql_query($query3) = "insert into match (tutor_id, student_id, school_id) values ('$tutor_id','$student_id','$school_id')";
The function name is spelled wrong and the parameter shouldn't be $query3
but the actual query:
mysql_query("insert into match (tutor_id, student_id, school_id) values ('$tutor_id','$student_id','$school_id')");
Basically you have to insert the output of the previous query into the database.
change
$check_availability = "select *
from tutors, students
where tutor_availability = '$student_availability'
AND (tutor_subject_1 = '$student_subject_1'
OR tutor_subject_1 = '$student_subject_2'
OR tutor_subject_2 = '$student_subject_2'
OR tutor_subject_2 = '$student_subject_1')";
to
$check_availability = "insert into match (tutor_id, student_id, school_id)
select tutors.id, students.id, students.school_id
from tutors, students
where tutor_availability = '$student_availability'
AND (tutor_subject_1 = '$student_subject_1'
OR tutor_subject_1 = '$student_subject_2'
OR tutor_subject_2 = '$student_subject_2'
OR tutor_subject_2 = '$student_subject_1')";
You have to loop through the row to get the values to insert:
if(mysql_query($query2)){
$check_availability = "select *
from tutors, students
where tutor_availability = '$student_availability'
AND (tutor_subject_1 = '$student_subject_1'
OR tutor_subject_1 = '$student_subject_2'
OR tutor_subject_2 = '$student_subject_2'
OR tutor_subject_2 = '$student_subject_1')";
$run_5 = mysql_query($check_availability);
if(mysql_num_rows($run_5)>0) {
echo "<script>alert('we have a match')</script>";
while($row = mysql_fetch_assoc($run_5)) {
$tutor_id = $row['tutor_id'];
$student_id = $row['student_id'];
$school_id = $row['school_id'];
mysql_query("insert into match (tutor_id, student_id, school_id) values ('$tutor_id','$student_id','$school_id')");
}
} else{
echo "<script>alert('no match found')</script>";
}
}
I don't know the exact field names, but it should point you in the right direction.
Maybe try using mysql_fetch_row($run_5) and change the select query to only pull out tutor_id, student_id and school_id.
if(mysql_query($query2)){
$check_availability = "select t.tutor_id, s.student_id, t.school_id
from t.tutors, s.students
where t.tutor_availability = '$student_availability'
AND (t.tutor_subject_1 = '$student_subject_1'
OR t.tutor_subject_1 = '$student_subject_2'
OR t.tutor_subject_2 = '$student_subject_2'
OR t.tutor_subject_2 = '$student_subject_1')";
$run_5 = mysql_query($check_availability);
if(mysql_num_rows($run_5)>0) {
echo "<script>alert('we have a match')</script>";
while($row = mysql_fetch_row($run_5)) {
$tutor_id = $row[0];
$student_id = $row[1];
$school_id = $row[2];
mysql_query("insert into match (tutor_id, student_id, school_id) values ('$tutor_id','$student_id','$school_id')");
}
} else{
echo "<script>alert('no match found')</script>";
}
}
