我在製作一個中西藥查詢系統
它有中藥(herb)和西藥(drug)兩個查詢欄位
colherb為接受中藥欄位傳來的值，預設值1，執行階段值$_GET['herb']
coldrug為接受西藥欄位傳來的值，預設值1，執行階段值$_GET['drug']
我為此寫了兩個語法，分別讓它可以單向查詢(其中一個欄位為空時)和交叉查詢(2個欄位都有資料時)
使用if...else...
寫入資料集(查詢)的SQL欄位裡
if ($_GET['drug'] or $_GET['herb'] == NULL) {
SELECT *
FROM medicine
WHERE TCMCName = 'colherb' OR TCMEName = 'colherb' OR TCMGName = 'colherb' UNION SELECT * FROM medicine WHERE `Western Medicine` = 'coldrug' }
else {
SELECT * FROM medicine WHERE TCMCName in ('colherb') and `Western Medicine` in ('coldrug') UNION SELECT * FROM medicine WHERE TCMEName in ('colherb') and `Western Medicine` in ('coldrug') UNION SELECT * FROM medicine WHERE TCMGName in ('colherb') and `Western Medicine` in ('coldrug')}
可是按F12測試網頁輸入資料後卻出現
Parse error: syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING in C:\AppServ\www\cawm\Search.php on line 12
請問我的語法哪邊有錯誤呢?
附上Search.php on line 12的程式碼
$query_show = sprintf("if ($_GET['drug'] or $_GET['herb'] == NULL) { SELECT * FROM medicine WHERE TCMCName = '%s' OR TCMEName = '%s' OR TCMGName = '%s' UNION SELECT * FROM medicine WHERE `Western Medicine` = '%s' } else { SELECT * FROM medicine WHERE TCMCName in ('%s') and `Western Medicine` in ('%s') UNION SELECT * FROM medicine WHERE TCMEName in ('%s') and `Western Medicine` in ('%s') UNION SELECT * FROM medicine WHERE TCMGName in ('%s') and `Western Medicine` in ('%s')}", $colherb_show,$colherb_show,$colherb_show,$coldrug_show,$colherb_show,$coldrug_show,$colherb_show,$coldrug_show,$colherb_show,$coldrug_show);
拜託大家...我真的不知道哪邊出問題>''<
