我在输入格式里面启用了php输入格式，让后在创建page内容的时候输入php代码：

<?php
function freemind_filter($courseid, $text) {
    global $CFG;
    $pattern = '(.+)<a .*href=\"(.+)\.mm.*>(.*)</a>(.*)';

    $match = ereg($pattern,$text,$regs);

    if($match){
        $pre = $regs[1];
        $basename = $regs[2];
        $discarded = $regs[3];
        $post = $regs[4];

        $width  = '100%';
        $height = '100%';

        $pattern = 'width=([0-9]+)';
        $match = ereg($pattern,$text,$regs);

        if($match){
            $width=$regs[1];

        }

        $pattern = 'height=([0-9]+)';
        $match = ereg($pattern,$text,$regs);

        if($match){
            $height=$regs[1];

        }
        $text       = $pre . "<br/>";
        $text      .= ' <applet';
        $text      .= ' codebase="./"';
        $text      .= ' archive="' . $CFG->wwwroot . '/userfiles/flash/freemindbrowser.jar"';
        $text      .= ' code="freemind.main.FreeMindApplet.class"';
        $text      .= ' width="100"';
        $text      .= ' height="100"'; 
        $text  .= '>';
        $text  .= ' <param name="type" value="application/x-java-applet;version=1.4">';
        $text  .= ' <param name="scriptable" value="false">';
        $text  .= ' <param name="modes" value="freemind.modes.browsemode.BrowseMode">';
        $text  .= ' <param name="initial_mode" value="Browse">';
        $text  .= ' <param name="selection_method" value="selection_method_direct">';
        $text  .= ' <param name="browsemode_initial_map" value=' . '"map.mm">';

        $text  .= '</applet> ';
        $text  .= "<br/>" . $post;

        $search = array();
        $search[0] = "/XXXXXX/";
        $search[1] = "/YYYYYY/";
        $search[2] = "/ZZZZZZ/";

        $replace = array();
        $replace[0] = $width; 
        $replace[1] = $height; 
        $replace[2] = $basename; 

        $text = preg_replace($search, $replace, $text);
    }
    return $text;
}
?>
