I need to search with multi variable and sort - php

Question

I can search multiple value with mysql.
I need to implement SORT BY on it
This is my coding which is working perfect
$conditions = array();
if ($key) {
$conditions[] = 'job_title LIKE "%'.$key.'%"';
}
if ($category) {
$conditions[] = 'job_category = "'.$category.'"';
}
if ($location) {
$conditions[] = 'job_location = "'.$location.'"';
}
if ($country) {
$conditions[] = 'job_country = "'.$country.'"';
}
if ($salary) {
$conditions[] = 'job_salary >= "'.$salary.'"';
}
$sqlStatement = 'SELECT * FROM jobs JOIN job_category ON jobs.job_category=job_category.category_id '.implode(' AND ', $conditions);
When I apply SORT BY
like this
if ($sort)
{
$conditions[] = 'ORDER BY "'.$sort.'"';
$sqlStatement = 'SELECT * FROM jobs JOIN job_category ON jobs.job_category=job_category.category_id '.implode(' AND ', $conditions);
}
else
{
$sqlStatement = 'SELECT * FROM jobs JOIN job_category ON jobs.job_category=job_category.category_id '.implode(' AND ', $conditions);
}
result is
Blockquote
SELECT * FROM jobs JOIN job_category ON jobs.job_category=job_category.category_id job_location = "Manjeri" AND ORDER BY "job_salary"

Answer 1

you shouldn't implode your order by as a condition.. it's not one..
just append it onto the end like so:
$sqlStatement = 'SELECT * FROM jobs JOIN job_category ON jobs.job_category=job_category.category_id ';
if( sizeof($conditions)) {
$sqlStatement .= ' WHERE ' . implode(' AND ', $conditions);
}
if($sort) {
$sqlStatement .= ' ORDER BY "'.$sort.'"';
}
