我试图用jQuery和PHP做一些简单的AJAX搜索。但是,我似乎无法使用正确的搜索字符串。我想按标题搜索,如果标题没有看到设置,只需在点击搜索时显示所有结果。此外,我想将结果显示为漂亮的HTML,而不是返回类似JSON的代码。像这样的东西:
$book["title"]
$book["author"]
$book["description"]
SQL设置:
表名:书籍 表字段:id,title,author,description
HTML:
<div id="search">
<form action="#">
<p><label for="title">Book Title:</label> <input type="text" id="search_title" name="search_title"></p>
<p><input type="submit" id="search_submit" name="search_submit" value="Search!"></p>
<p><em><small>For example A Game of Thrones or The Lord of the Rings</small></em></p>
<hr>
</form>
</div>
<div id="search_results">
</div>
<script>
$(document).ready(function() {
$("#search_submit").on("click", function() {
var searchTitle = $("#search_title").val(),
data = 'title=' + searchTitle;
if(searchTitle) {
$.ajax({
type: "POST",
url: "getBooks.php",
data: data,
success: function(res)
{
$("#search_results").html(res);
}
});
}
return false;
});
});
</script>
PHP:
if(isset($_GET["title"])) {
$title = $_GET["title"];
}
if(isset($title) && !empty($title)) {
$pdo_title = "WHERE title LIKE '%" . $title . "%'";
} else {
$pdo_title = "";
}
$pdo_books = "books";
$pdo = new PDO("mysql:dbname=removed;host=removed","removed","removed");
$statement = $pdo->prepare("SELECT * FROM $pdo_books $pdo_title");
$statement->execute();
$results = $statement->fetchAll(PDO::FETCH_ASSOC);
$json = json_encode($results);
echo $json;

您已在ajax中提及该方法,并尝试使用$title = $_GET["title"];
尝试使用
$title = $_POST["title"];

if(isset($_POST["title"])) {
$title = $_POST["title"];
}

如果它是关于从JSON格式化HTML格式的输出,那么在你的jQuery代码中,你需要为数组中的每个json对象解析json并重复循环,并动态地将HTML添加到你的页面。
if(searchTitle) {
$.ajax({
type: "POST",
url: "getBooks.php",
data: data,
success: function(res)
{
var my_table="<table>";
$.each(res, function(i, obj){
my_table+="<tr> <td> "+obj.clumn_name+" </td> <td> "+obj.clumn_name2+" </td> </tr> ";
});
my_table+"</table>";
$("#search_results").html(my_table);
}
});
}
