我有一個漫畫網站。它具有的功能是允許用戶搜索漫畫...搜索將立即解析輸入並根據匹配的標題和關鍵字返回縮略圖結果。PHP搜索:使用jquery改變一個php的值
最初,搜索將返回所有結果,並且邊界搜索框將無限向下展開,並保存每個漫畫結果。我認爲將結果限制爲4可能是一個很好的接觸,並且如果用戶選擇這樣做,則會顯示一條消息,如「加載5個剩餘圖像」。
如果他們點擊該消息,我想限制php變量被刪除或更改。
到目前爲止,它加載與限制,並顯示一個鏈接...
編輯:最新代碼:
search_field.php(即獲得的搜索文件包含在一個頁面中......此文件通過JQuery調用search.php):
<?php $site = (isset($_GET['site']) ? ($_GET['site']) : null); ?>
<div id="sidebar" class="searchborder">
<!--Allow users to search for comic-->
<!--<span class="search">Search for <?php// echo (($site == "artwork") ? 'artwork' : 'a comic'); ?> </span>-->
<script type="text/javascript">
function GetSearch(mySearchString){
$.get("./scripts/search.php", {_input : mySearchString, _site : '<?php echo $site ?>'},
function(returned_data) {
$("#output").html(returned_data);
}
);
}
</script>
<center>
<table>
<tr>
<td>
<span class="search">
<img src="./images/SiteDesign/Search.png" />
<input type="text" onkeyup="GetSearch(this.value)" name="input" value="" />
<!--<input id="site" type="hidden" value="<?php// echo $site; ?>">-->
</span>
</td>
</tr>
</table>
</center>
<span id="output"> </span>
</div>
search.php中,這就是所謂的解析字符串並返回結果的文件:
<?php

//if user goes to hittingtreeswithsticks.com... no "site" value will be set... so I need to set one
