php – 尝试在wpdb中使用IN()时出现问题

我有这个：

$villes = '"paris","fes","rabat"';
$sql    = 'SELECT distinct telecopie FROM `comptage_fax` WHERE `ville` IN(%s)';
$query  = $wpdb->prepare($sql, $villes);

当我做一个echo $查询;我得到：

SELECT distinct telecopie FROM `comptage_fax` WHERE `ville` IN('\"CHAPELLE VIVIERS \",\"LE MANS \",\"QUEND\"')

我遇到的问题是$wpdb添加’in IN(‘…’)

有人可以帮忙,谢谢

解决方法:

试试这段代码(修复)：

// Create an array of the values to use in the list
$villes = array("paris", "fes", "rabat");    

// Generate the SQL statement.
// The number of %s items is based on the length of the $villes array
$sql = "
  SELECT DISTINCT telecopie
  FROM `comptage_fax`
  WHERE `ville` IN(".implode(', ', array_fill(0, count($villes), '%s')).")
";

// Call $wpdb->prepare passing the values of the array as separate arguments
$query = call_user_func_array(array($wpdb, 'prepare'), array_merge(array($sql), $villes));

echo $query;

> implode()
> array_fill()
> call_user_func_array()
> array_merge()
