Now the user must input the data as specified in the
next file, index3.wml. We ask the user to insert the name of a subject
or the surname of a professor. Look how variables are sent, in this
page and in the previous. The syntax is pretty complex, but it lets
you handle all the whole process, with only a few files.
<?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).<br />\n");
} else if (${$choice} == "subject") {
echo ("the subject (or part of it).<br />\n");
} else {
echo ("Maybe there is some problem.<br />\n");
}
echo ("<input type=\"text\" name=\"${$choice}\" />");
?>
<do type="text" label="Go">
<go method="get" href="query.wml">
<?php
echo ("<postfield name=\"$choice\" value=\"$"."$choice"."\"/>");
echo ("<postfield name=\"${$choice}\" value=\"$"."${$choice}"."\"/>");
?>
</go>
</do>
<p>
</p>
</card>
</wml>
