建立動態的WML站點(三)_PHP教程

接著使用者必須在下一個檔案（index3.wml）中輸入。我們要求使用者輸入科目的名字或教授的姓。你要留意一下變數在頁面之間是怎麼傳送的。文法看來有點複雜，不過可以讓你了解整個過程是怎麼透過幾個檔案來完成的。

寫查詢程式碼

以下的檔案負責處理查詢。它的名字是query.wml，我們將更詳細地分析它。


Header("內容類型：text/vnd.wap.wml");  
printf("n");  
printf("n");  
printf("n");  


// 下列各行是用來詢問 🎜>

$consulting_tables =  
"(professors left join teach on (professors.Id = teach.Id), subjects)"; > .Name, subjects.Subject , ";  
$consulting_columns .=  
"subjects.Cod_number, professors.Consulting_hour, professors.Consulting_place"; Cod_Subject = teach.Cod_subject ";  


// 以下各行是用來為查詢測驗時間建構SQL語句的  

$exams_tables= "(exams left join professors ON (exams. = professors. ), subjects)";  
$exams_columns= "subjects.Subject , subjects.Cod_number, professors.Surname, ";  
$exams_columns.= kamk. , exams.Test";  
$exams_query= "exams.Cod_Subject = subjects.Cod_Subject ";  

//// 查詢是用來為查詢句子測驗

if ($exams_data) {  

switch($exams_data) {  
case "subject":  
$exams_3query.Ssubect; ";  
break;  
case "surname":  
$exams_query.= " and professors.Surname like '%$surname%'";  break; 🎜>

// 以下各行是用來為查詢課程時間的sql語句增加查詢限制

if ($consulting_data) {  
switch($consulting_data) { "subject":  
$consulting_query  
.= " and subjects.Subject like '%$subject%'";  
;  break;  
}  
}  


// 處理與資料庫的連線function connect($tables, $data, $condition_passed) {  
//  
// put your password and username in next line  
// "$ ,"***","***");  

// put your database name in next line  

mysql_select_db("lanfranchi_co_uk",$db); $sql = "SELECT $data FROM $tables WHERE $condition_passed order by professors.Surname";  
$result = mysql_query($sql,$db);  
return $result);

// 這個函數產生課程時間的wml程式碼

function consulting_print($consulting_result) {  
global $file;  
printf("n);  (" ＜P＞Receiving hours  

n");  
while ($myrow = mysql_fetch_row($consulting_result)) { ＠ 1]＜/P​​＞n");  
printf(" ＜P＞$myrow[2]＜/P＞n");  
printf(" ＜P＞$myrow[3]＜/＞＜ n");  
printf(" ＜P＞$myrow[4]＜/P＞n");  
printf(" ＜P＞$myrow[5]＜/P＞n"); >}  
printf("＜/CARD＞n");  
}  


// 這個函數產生測驗時間表的wml代碼

exams_result) {  
global $file;  
printf("＜CARD id='"card1"' title='"hours"'＞n");  
printf(" ＜.P. >
n");  
while ($myrow = mysql_fetch_row($exams_result)) {  
printf(" ＜P＞$myrow[2], $myrow[3]＜/＞n" ;  
printf(" ＜P＞$myrow[0]＜/P＞n");  
printf(" ＜P＞$myrow[1]]＜/P＞n"); (" ＜P＞$myrow[4], $myrow[5]＜/P＞n");  
printf(" ＜P＞$myrow[7]＜/P＞n"); (" ＜P＞$myrow[6]＜/P＞n");  
}  
printf("＜/CARD＞n");  
} / 檢查你時候選擇授課時間或測驗時間，連接資料庫並且呼叫產生wml程式碼的函數

if ($consulting_data) {  
$connection_result =  
connect($consulting_$consulting_fconsulting_fconsulting_$consulting_H. consulting_query);  
consulting_print($connection_result);  
}
if ($exams_data) {  
$connection_result =  
connect($exams_tables, $ exams_columns, $ s_query); f("＜ /WML＞n");

　　好，完成了。你已經建立了首個基於MySQL資料庫的PHP/WML頁面了，自己繼續實踐一下吧。
