php没有从html表单中获取变量

Question

我是PHP的新手,所以我不确定我在这里做错了什么...

<?php

$date = $_POST['date'];
$promoter = $_POST['promoter'];
$email = $_POST['email'];
$headliner = $_POST['headliner'];
$headsite = $_POST['headsite'];
$headdesc = $_POST['headdesc'];
$support1 = $_POST['support1'];
$sup1site = $_POST['sup1site'];
$sup1desc = $_POST['sup1desc'];
$support2 = $_POST['support2'];
$sup2site = $_POST['sup2site'];
$sup2desc = $_POST['sup2desc'];
$support3 = $_POST['support3'];
$sup3site = $_POST['sup3site'];
$sup3desc = $_POST['sup3desc'];
$support4 = $_POST['support4'];
$sup4site = $_POST['sup4site'];
$sup4desc = $_POST['sup4desc'];
$support5 = $_POST['support5'];
$sup5site = $_POST['sup5site'];
$sup5desc = $_POST['sup5desc'];

print '<b>$date</b> - info: <a href="mailto:$email">$promoter</a><br />';
print '<b>$headliner</b> [<a href="$headsite" target="_blank">$headsite</a>]<br />';
print '<i>$headdesc</i><br />';
print '<b>$support1</b> [<a href="$sup1site" target="_blank">$sup1site</a>]<br />';
print '<i>$sup1desc</i><br />';
print '<b>$support2</b> [<a href="$sup2site" target="_blank">$sup2site</a>]<br />';
print '<i>$sup2desc</i><br />';
print '<b>$support3</b> [<a href="$sup3site" target="_blank">$sup3site</a>]<br />';
print '<i>$sup3desc</i><br />';
print '<b>$support4</b> [<a href="$sup4site" target="_blank">$sup4site</a>]<br />';
print '<i>$sup4desc</i><br />';
print '<b>$support5</b> [<a href="$sup5site" target="_blank">$sup5site</a>]<br />';
print '<i>$sup5desc</i><br />';

?>

这是我提交后的结果......

$date - info: $promoter<br />
$headliner [$headsite]<br />
$headdesc<br />
$support1 [$sup1site]<br />
$sup1desc<br />
$support2 [$sup2site]<br />
$sup2desc<br />
$support3 [$sup3site]<br />
$sup3desc<br />
$support4 [$sup4site]<br />
$sup4desc<br />
$support5 [$sup5site]<br />
$sup5desc

任何帮助将不胜感激.谢谢.

您必须使用双引号(")字符串来扩展它们中的变量.例如

print "<b>$date</b> - info: <a href=\"mailto:$email\">$promoter</a><br />";
