基于复选框的多个sql条件
我正在开发一种先进的搜索系统，可根据用户的技能搜索用户。这些是各种技能。
每项技能都存储在数据库中的单独列中，值为0＆amp; 1。
现在，当我搜索用户时，我使用OR条件，这样当我检查Access时，将找到具有Access技能的用户。以下是搜索条件的代码：
$query .= "SELECT * FROM wordpress_candidate
WHERE (city = '$cty')
OR (state = '$stt')";
if(isset($s_g_1)){ $query .= "OR (generala = '$s_g_1')"; }
if(isset($s_g_2)){ $query .= "OR (generalb = '$s_g_2')"; }
if(isset($s_g_3)){ $query .= "OR (generalc = '$s_g_3')"; }
if(isset($s_g_4)){ $query .= "OR (generald = '$s_g_4')"; }
//if(isset($s_g_5)){ $query .= "OR (generale = '$s_g_5')"; }
if(isset($s_g_6)){ $query .= "OR (generale = '$s_g_6')"; }
if(isset($s_g_7)){ $query .= "OR (generalf = '$s_g_7')"; }
if(isset($s_g_8)){ $query .= "OR (generalg = '$s_g_8')"; }
if(isset($s_g_9)){ $query .= "OR (generalh = '$s_g_9')"; }
if(isset($s_g_10)){ $query .= "OR (generali = '$s_g_10')"; }
if(isset($s_g_11)){ $query .= "OR (generalj = '$s_g_11')"; }
if(isset($s_g_12)){ $query .= "OR (generalk = '$s_g_12')"; }
if(isset($s_g_other)){ $query .= "OR (generall = '$s_g_other')"; }
if(isset($s_f_1)){ $query .= "OR (funda = '$s_f_1')"; }
if(isset($s_f_2)){ $query .= "OR (fundb = '$s_f_2')"; }
if(isset($s_f_3)){ $query .= "OR (fundc = '$s_f_3')"; }
if(isset($s_f_4)){ $query .= "OR (fundd = '$s_f_4')"; }
if(isset($s_f_5)){ $query .= "OR (funde = '$s_f_5')"; }
if(isset($s_f_6)){ $query .= "OR (fundf = '$s_f_6')"; }
if(isset($s_f_7)){ $query .= "OR (fundg = '$s_f_7')"; }
if(isset($s_f_8)){ $query .= "OR (fundh = '$s_f_8')"; }
if(isset($s_f_9)){ $query .= "OR (fundi = '$s_f_9')"; }
if(isset($s_f_10)){ $query .= "OR (fundj = '$s_f_10')"; }
if(isset($s_f_11)){ $query .= "OR (fundk = '$s_f_11')"; }
if(isset($s_f_12)){ $query .= "OR (fundl = '$s_f_12')"; }
if(isset($s_f_13)){ $query .= "OR (fundm = '$s_f_13')"; }
if(isset($s_f_other)){ $query .= "OR (fund = '$s_f_other')"; }
if(isset($s_a_1)){ $query .= "OR (acca = '$s_a_1')"; }
if(isset($s_a_2)){ $query .= "OR (accb = '$s_a_2')"; }
if(isset($s_a_3)){ $query .= "OR (accc = '$s_a_3')"; }
if(isset($s_a_4)){ $query .= "OR (accd = '$s_a_4')"; }
if(isset($s_a_5)){ $query .= "OR (acce = '$s_a_5')"; }
if(isset($s_a_6)){ $query .= "OR (accf = '$s_a_6')"; }
if(isset($s_a_7)){ $query .= "OR (accg = '$s_a_7')"; }
if(isset($s_a_8)){ $query .= "OR (acch = '$s_a_8')"; }
if(isset($s_a_9)){ $query .= "OR (acci = '$s_a_9')"; }
if(isset($s_a_10)){ $query .= "OR (accj = '$s_a_10')"; }
if(isset($s_a_11)){ $query .= "OR (acck = '$s_a_11')"; }
if(isset($s_a_other)){ $query .= "OR (accl = '$s_a_other')"; }
if(isset($s_p_1)){ $query .= "OR (puba = '$s_p_1')"; }
if(isset($s_p_2)){ $query .= "OR (pubb = '$s_p_2')"; }
if(isset($s_p_3)){ $query .= "OR (pubc = '$s_p_3')"; }
if(isset($s_p_4)){ $query .= "OR (pubd = '$s_p_4')"; }
if(isset($s_p_5)){ $query .= "OR (pube = '$s_p_5')"; }
if(isset($s_p_6)){ $query .= "OR (pubf = '$s_p_6')"; }
if(isset($s_p_7)){ $query .= "OR (pubg = '$s_p_7')"; }
if(isset($s_p_8)){ $query .= "OR (pubh = '$s_p_8')"; }
if(isset($s_p_9)){ $query .= "OR (pubi = '$s_p_9')"; }
if(isset($s_p_other)){ $query .= "OR (pubj = '$s_p_other')"; }
if(isset($s_i_1)){ $query .= "OR (ita = '$s_i_1')"; }
if(isset($s_i_2)){ $query .= "OR (itb = '$s_i_2')"; }
if(isset($s_i_3)){ $query .= "OR (itc = '$s_i_3')"; }
if(isset($s_i_4)){ $query .= "OR (itd = '$s_i_4')"; }
if(isset($s_i_5)){ $query .= "OR (ite = '$s_i_5')"; }
if(isset($s_i_6)){ $query .= "OR (itf = '$s_i_6')"; }
if(isset($s_i_7)){ $query .= "OR (itg = '$s_i_7')"; }
if(isset($s_i_8)){ $query .= "OR (ith = '$s_i_8')"; }
if(isset($s_i_other)){ $query .= "OR (iti = '$s_i_other')";
此代码工作正常，但如果同时检查Access和Crystal，我想根据这两个标准搜索用户，但它只按一个搜索。我知道我可以检查两个复选框的条件并在查询中添加AND。但是我如何为所有复选框执行此操作？

3 个答案:
答案 0 :(得分：0)
使用AND子句代替OR来搜索
if(isset($s_g_1)){ $query .= "AND (generala = '$s_g_1')"; }
if(isset($s_g_2)){ $query .= "AND (generalb = '$s_g_2')"; }
我还建议，使用循环检查所有这些。
答案 1 :(得分：0)
我认为你需要一个输入来选择类型＆＃34;和＆＃34;的搜索。或＆＃34;或＆＃34;
$query .= "SELECT * FROM wordpress_candidate
WHERE (city = '$cty')
OR (state = '$stt')";
if (searchType = 'AND')
{
$and_or = 'AND'
}
else
{
$and_or = 'OR'
}
if(isset($s_g_1) && ($s_g_1)) { $query .= $and_or + " (generala = '$s_g_1')"; }
if(isset($s_g_2) && ($s_g_2)) { $query .= $and_or + " (generalb = '$s_g_2')"; }
答案 2 :(得分：0)
据我所知，您只想过滤用户检查技能。如果未选中复选框，则无论用户是否具备该技能，都无关紧要;正确的吗？
在这里，您只过滤积极的技能：
if ($s_g_1) { $query .= " AND (generala = 1) "; }
if ($s_g_2) { $query .= " AND (generalb = 1) "; }
...
因此，如果选择“访问”和“水晶”，您将获得具有这两种技能（AND）的所有用户，无论其他技能如何。
（我不会在if条件中与isset()核对 - 我只想查询我的查询中的条件，如果$s_g_1不是0（=如果选中复选框） 。如果您不知道，是否定义了$s_g_1，请使用!empty($s_g_1)进行检查以避免NOTICE。）
