我让搜索表单从 MySQL 中的多个其他表中查询一个内部连接表。我正在使用带有 Xampp/Apache 的本地 Intranet 当我在 PHPMyAdmin 中运行 SQL 时，它运行 Perfect 并产生完全符合我希望它们出现在我的网站上的结果。
我的数据库名称是：loodt 我的表格是：ee、er、aa、adjuster 和律师。我在 ee 表上有其他表的外键（ee.er_id = er.id）等...
但是，当我尝试在我的网站上运行搜索时，它会弹出一条错误消息“无法查询数据库以获取搜索结果，MYSQL 错误表'loodt.ee a”不存在。”所以我尝试取消快捷方式字母[在下面的代码中引用]（A、B、C、D< E 和 F）并输入 ee.name、er.name 等...而不是分配这些字母，它也不起作用。
在几天前开始修改它之前，我已经使用搜索引擎从单个表中查询结果，所以我知道它可以工作，并且必须是“临时”表的问题，当然我缺乏知识。
这是搜索引擎的javascript：
$(function(){
//Hide the result list on load
$('#results-list').hide();
//Click event when search button is pressed
$('#search').click(function(){
doSearch();
});
//Keypress event to see if enter was pressed in text input
$('#text').keydown(function(e){
if(e.keyCode == 13){
doSearch();
}
});
});
>
function doSearch() {
var searchText = $('#text').val();
//Rehide the search results
$('#results-list').hide();
$.ajax({
url: './search.php',
type: 'POST',
data: {
'text': searchText
},
beforeSend: function(){
//Lets add a loading image
$('#results-holder').addClass('loading');
},
success: function(data) {
//Take the loading image away
$('#results-holder').removeClass('loading');
//Was everything successful, no errors in the PHP script
if (data.success) {
//Clear the results list
$('#results-list').empty();
//Display the results
//Check to see if there are any results to display
if(data.results.length > 0) {
//Loop through each result and add it to the list
$.each(data.results, function(){
//Give the list element a rel with the data results ID incase we want to act on this later, like selecting from the list
$('#results-list').append(
"<li rel='" + this.A_name + "'>" + this.D_name + " | " + this.A_file_no + " | " + this.A_claim_no + " | " + this.A_adj_no + " | " + this.F_acronym + " | " + this.A_doi + " | " + this.A_opened + " | " + this.A_status + " | " + this.A_redwells + " | " + this.E_firm_name + " | " + this.B_name + " | " + this.C_initials + " </li>");
});
} else {
//If there are no results, inform the user - add 'no-results' class so we can style it differently
$('#results-list').append("<li class='no-results'>Your search did not return any results</li>");
}
//Show the results list
$('#results-list').fadeIn();
} else {
//Display the error message
alert(data.error);
}
}
});
}
上面的 javascript 文件是从我的标题中的索引页调用的，不确定这是否重要。这是在上面的 javascript 代码中调用的 search.php 文件。
