目前我有一個索引頁面,它使用simpleXML顯示來自XML頁面的值。而一個打印到另一個頁面的搜索功能,我想要做的是刷新首頁,以便在點擊按鈕時僅顯示搜索結果。使用XPath和php進行搜索
索引頁。
<?php
$action = "searchFunctionDescription.php";
?>
<form name="search" method="get" action=<?php echo "\"$action"?>">
<input name="txtSearch" type="text" id="txtSearch" size="30"/>
<input type="submit" value="Search" />
<?php
// load the xml file into a simplexml instance variable
$holiday = simplexml_load_file('holidays.xml');
// draw a table and column headers
echo "<table border=\"1\">";
// iterate through the item nodes displaying the contents
foreach ($holiday->channel->item as $holiday) {
echo "<tr><td><a href=\"{$holiday->link}\">{$holiday->title}</a>" . "<br />" .
"{$holiday->pubDate}" . "<br />" .
"{$holiday->description}</td>" . "<br />" .
"</tr>";
}
echo "</table>";
?>
然後我有我的searchProcessDescription.php頁
<?php
// create an instance
$holidayDoc = simplexml_load_file('holidays.xml');
// Passes txtSearch to current script from searchFormDescription.php
$txtSearch = $_GET['txtSearch'];
// Informs user of what they have searched
echo "Showing Results for <strong>$txtSearch</strong>";
// set the query using the description
if (!is_null($txtSearch)) {
$qry = "//channel/item[description[contains(text(),\"$txtSearch\")]]";
}
else {
// blank search entered so all holidays are shown.
$qry = "/channel/'ALL'";
}
// execute the xpath query
$holidays = $holidayDoc->xpath($qry);
// now loop through all holidays and entered results into table
echo "<table border=\"0\">\n";
foreach ($holidays as $holiday)
{
echo "<tr>\n";
echo "<td><a href=\"{$holiday->link}\">{$holiday->title}</a></td>";
echo "<td>{$holiday->description}</td>";
echo "<td>{$holiday->pubDate}</td>";
echo "<td><input type=\"checkbox\" name=\"saveCB\" value=\"3\"/></td>";
echo "</tr>\n";
}
echo "</table>\n";
?>
有一個簡單的方法來此過程中添加到索引頁面,該頁面被點擊搜索按鈕時刷新?
感謝
有一些錯誤,我正在會見了: 注意:未定義的變量:節日第65行 注意:試圖讓行非對象的屬性65 注意:試圖讓非財產上線65 -object 警告:未定義變量::行動作77 – 2012-03-28 11:12:10
對不起,則應在此處修改:爲第65行 通知的foreach()提供參數無效 <形式名稱=「搜索」方法=「POST」 action =#「> 其他錯誤是奇怪的,所有變量似乎inizialized,行號不正確:我所有的腳本有59行! – Gian 2012-03-28 13:49:27
我找到了...請檢查變量$ holidayDoc和$ holiday,我修改了附加的代碼,對不起 – Gian 2012-03-28 13:53:58
