小编use*_*353的帖子

这是我的SQL查询:

SELECT DISTINCT 
   k.*, m.title as city, w.title as state 
FROM 
   konta__kategoria kat, konta k 
INNER JOIN 
   miejscowosci as m ON k.miejscowosc = m.id 
INNER JOIN 
   wojewodztwa as w ON k.wojewodztwo = w.id 
LEFT JOIN 
   kategorie as cat ON cat.id = kat.kategoria 
WHERE 
   kat.kategoria IN (1610,1609,1608,1607,1606,1605,1611,1612,1613,1614,1615,1616,1617,1618,1619,1620,1621,1622,1623,1624,1625,1626,1627,1628,1629,1630,1631,1632,1633,1634,1635,1636,1637,1638,1639,1640,1641,1642,1643,1644,1645,1646,1647,1648,1649,1650,1651,1652,1653,1654,1655,1656,1657,1658,1659,1660,1661,1662,1663,1664,1665,1666,1667,1668,1669,1670,1671,1672,1673,6) 
   AND kat.parent_id = k.id 
   AND k.dsc LIKE "%%" 
   AND deleted = 0 
ORDER BY 
   k.nazwa

我收到错误:

#1054 - Unknown column 'kat.kategoria' in 'on clause'

我删除时它正在工作

LEFT JOIN kategorie as cat ON cat.id = kat.kategoria …

这是我的字符串

component/content/article?id=9

如何从中动态获得9？

我想在字符串上做,而不是url,并且可能存在更多paremateres的情况,例如url.我想像$ _GET一样做得很好,但是在字符串上

重写问题(由Ayesh K撰写):

我有一个包含URL路径和查询字符串的字符串.我想将查询字符串解析为一个键和值数组,就好像它是当前页面的查询字符串,所以我可以从中获取它们$_GET.

例如,我有以下字符串:

component/content/article?id=9

现在我想从数组中获取idvalue(9).如何解析此类字符串以分隔查询字符串并将其转换为数组？
