我需要使用多变量进行搜索并排序

Question

我可以使用 mysql 搜索多个值。 我需要对其实施 SORT BY

它工作得很好

   $conditions = array();
if ($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);

这是我的编码，当我应用 SORT BY 时， 就像这个

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);
}

结果是

块引用 SELECT * FROM jobs JOIN job_category ON jobs.job_category=job_category.category_id job_location = "Manjeri" AND ORDER BY "job_salary" 警告：mysql_fetch_array() 期望参数 1 为资源，布尔值在 /Applications/XAMPP/xamppfiles/htdocs/work/mobjob/test.php 第 41 行给出

你不应该将你的订单作为一个条件..它不是一个..

只需将其附加到末尾，如下所示：

$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.'"';
}
