也或许是因为我还没有真正的学到深处吧,说实在的,PHP中的很多高级点的应用,如PHP类、PHP函数基本还是不懂吧! 接着用户必需鄙人一个文件(index3.wml)中输出。咱们请求用户输出科目标名字或传授的姓。你要寄望一下变量在页面之间是如何传送的。语法看来有点庞杂,不外可让你懂得全部进程是如何经由过程几个文件来完成的。
<?php
Header("Content-type: text/vnd.wap.wml");
header("Cache-Control: no-cache, must-revalidate");
header("Pragma: no-cache");
echo ("<?xml version='1.0'?>;");
>;
<!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.1//EN"
"http://www.wapforum.org/DTD/wml_1.1.xml" >; <WML>
<CARD id=card3 title=Name>
<?php
echo ("<p>Insert ");
if (${$choice} == "surname") {
echo ("professor's surname (or part of it).n");
} else if (${$choice} == "subject") {
echo ("the subject (or part of it).n");
} else {
echo ("Maybe there is some problem.n");
} echo ("<INPUT name='"${$choice}"' type='"text"'>");
?>
<DO type="text" label="Go">
<GO href="query.wml" method="get">
<?php
echo ("<POSTFIELD value='"$"."$choice".""/' name='"$choice"'>");
echo ("<POSTFIELD value='"$"."${$choice}".""/' name='"${$choice}"'>");
?>
</GO>
</DO>
<P></P>
</CARD>
</WML>
<DO type="text" label="Go">
<GO href="index3.wml#card3" method="get">
<?php
echo ("<POSTFIELD value='"$"."$choice".""/' name='"$choice"'>");
echo ("<POSTFIELD value='"$choice"/' name='"choice"'>");
?>
</CARD>
</WML>
写查询代码
以下的文件担任处置查询。它的名字是query.wml,咱们将更具体地剖析它。
<?php
Header("Content-type: text/vnd.wap.wml");
printf("<?xml version="1.0"?>n");
printf("n");
printf("n");
// 以下各行是用来为查询讲课工夫机关SQL语句的
$consulting_tables =
"(professors left join teach on (professors.Id = teach.Id), subjects)";
$consulting_columns =
"professors.Surname, professors.Name, subjects.Subject , ";
$consulting_columns .=
"subjects.Cod_number, professors.Consulting_hour, professors.Consulting_place";
$consulting_query=
"subjects.Cod_Subject = teach.Cod_subject ";
// 以下各行是用来为查询检验工夫机关SQL语句的
$exams_tables= "(exams left join professors ON (exams.Id = professors.Id), subjects)";
$exams_columns= "subjects.Subject , subjects.Cod_number, professors.Surname, ";
$exams_columns.= "professors.Name, exams.Date, exams.Time, exams.Room, exams.Test";
$exams_query= "exams.Cod_Subject = subjects.Cod_Subject ";
// 以下各行是用来为查询检验工夫表的sql语句增添查询限制
if ($exams_data) {
switch($exams_data) {
case "subject":
$exams_query.= " and subjects.Subject like '%$subject%'";
break;
case "surname":
$exams_query.= " and professors.Surname like '%$surname%'";
break;
}
}
// 以下各行是用来为查询讲课工夫的sql语句增添查询限制
if ($consulting_data) {
switch($consulting_data) {
case "subject":
$consulting_query
.= " and subjects.Subject like '%$subject%'";
break;
case "surname":
$consulting_query.= " and professors.Surname like '%$surname%'";
break;
}
}
// 处置与数据库的毗连
function connect($tables, $data, $condition_passed) {
//
// put your password and username in next line
//
$db = mysql_pconnect("localhost","***","***");
// put your database name in next line
mysql_select_db("lanfranchi_co_uk",$db);
$sql = "SELECT $data FROM $tables WHERE $condition_passed order by professors.Surname";
$result = mysql_query($sql,$db);
return $result;
}
// 这个函数发生讲课工夫的wml代码
function consulting_print($consulting_result) {
global $file;
printf("n");
printf(" <P>Receiving hours
n");
while ($myrow = mysql_fetch_row($consulting_result)) {
printf(" <P>$myrow[0], $myrow[1]</P>n");
printf(" <P>$myrow[2]</P>n");
printf(" <P>$myrow[3]</P>n");
printf(" <P>$myrow[4]</P>n");
printf(" <P>$myrow[5]</P>n");
}
printf("</CARD>n");
}
// 这个函数发生检验工夫表的wml代码
function print_exams($exams_result) {
global $file;
printf("<CARD id='"card1"' title='"hours"'>n");
printf(" <P>Examinations hours
n");
while ($myrow = mysql_fetch_row($exams_result)) {
printf(" <P>$myrow[2], $myrow[3]</P>n");
printf(" <P>$myrow[0]</P>n");
printf(" <P>$myrow[1]]</P>n");
printf(" <P>$myrow[4], $myrow[5]</P>n");
printf(" <P>$myrow[7]</P>n");
printf(" <P>$myrow[6]</P>n");
}
printf("</CARD>n");
}
// 反省你时分选择讲课工夫或检验工夫,毗连数据库而且挪用发生wml代码的函数
if ($consulting_data) {
$connection_result =
connect($consulting_tables, $consulting_columns, $consulting_query);
consulting_print($connection_result);
}
if ($exams_data) {
$connection_result =
connect($exams_tables, $ exams_columns, $ exams_query);
print_exams($connection_result);
}
printf("</WML>n");
?>
好,完成了。你已创立了首个基于MySQL数据库的PHP/WML页面了,本人持续理论一下吧。 算是1个熟悉的过程,所以c语言的基础有就更好,没有也不怕。 |
