php - mysql 用 PHP 查询 if 语句？

Question

和$country值$job_type来自下拉列表

if ($country == 'All' && $job_type == 'All') {
    $data = mysql_query("SELECT * FROM cv ")
}else {
    $data = mysql_query("SELECT * FROM cv WHERE country='$country' AND job='$job_type'")      
}

Answer 1

你似乎错过了一些;，试试这个：

if ($country == 'All' && $job_type == 'All') 
{
  $data = mysql_query("SELECT * FROM cv WHERE country='$country' AND job='$job_type'");
} else {
  $data = mysql_query("SELECT * FROM cv");
}

本杰明有一点，你的 IF 逻辑似乎不正确。也许你想要这个？

if ($country == 'All' && $job_type == 'All') 
{
  $data = mysql_query("SELECT * FROM cv");
} else {
  $data = mysql_query("SELECT * FROM cv WHERE country='$country' AND job='$job_type'");
}
