如何根据具体领域进行搜索？
我要求在我们的网站上添加搜索部分，然后他们会像这样单独添加它。正如你在下面的图片中所看到的，我做了所有事情并且它正在工作。
我现在想要的是当我写作者姓名或姓氏然后选择最新的更新，日期范围或所有可用日期，然后点击搜索并获得结果。我可以通过单独搜索获得结果，但是当我输入选择日期的作者姓名时，我无法获得准确的结果。
以下是按字段代码搜索：
<?php
$user_id = $_SESSION['projectUserId'];
$text = $_POST['text'];
$field = $_POST['field'];
if($field == 'authors'){
$userQuerys = "SELECT * FROM user where name like '%$text%' or middlename like '%$text%' or surname like '%$text%'";
$users = mysqli_query($link, $userQuerys);
$userids = '';
while($a = mysqli_fetch_object($users))
{
$userids .= $a->user_id.',';
}
$userids = rtrim($userids,",");
}
if($_SESSION['projectUserType'] == 1 or $_SESSION['projectUserType'] == 4)
{
if($field == 'authors'){
$querys = "SELECT p.* FROM publication p left join pub_author a on a.pub_id=p.id where p.private = '0' and a.user_id in ('$userids')";
}else{
$querys = "SELECT p.* FROM publication p where p.private = '0' and $field = '$text'";
}
}
elseif($_SESSION['projectUserType'] == 3) {
$dep = $_SESSION['userDepartmantId'];
if($field == 'authors'){
$querys = "SELECT p.* FROM publication p left join pub_author a on a.pub_id=p.id where p.private = '0' and a.user_id in('$userids') and pub_department_id='$dep_id'";
}else{
$querys = "SELECT p.* FROM publication p where p.private = '0' and and $field = '$text'";
}
}
elseif($_SESSION['projectUserType'] == 5){
$deps = $_SESSION['userDepartmantId'];
$query = "SELECT * from uni_department where id='$dep_id'";
$faculties = mysqli_query($link, $query);
while($a = mysqli_fetch_object($faculties))
{
$fac_id = $a->faculty_id;
}
$query = "SELECT * from uni_department where faculty_id ='$fac_id'";
$faculties = mysqli_query($link, $query);
while($a = mysqli_fetch_object($faculties))
{
$facDeps .= $a->id . ',';
}
$ids = rtrim($facDeps,",");
if($field == 'authors'){
$querys = "SELECT p.* FROM publication p left join pub_author a on a.pub_id=p.id where p.private = '0' and a.user_id in('$userids') and p.pub_department_id IN ($ids)";
}else{
$querys = "SELECT p.* FROM publication p where p.private = '0' and $field = '$text' and pub_department_id IN ($ids)";
}
}
else{
echo '<script type="text/javascript">';
echo 'window.location = "unauthorized.php"';
echo '</script>';
}
$results5 = mysqli_query($link, $querys);
$num_rows5 = mysqli_num_rows($results5);
echo ' '.$num_rows5;
?>
这里是年份代码搜索：
<?php
$search = $_POST['search'];
$user_id = $_SESSION['projectUserId'];
$year = $_POST['year'];
$year2 = $_POST['year2'];
$yearfirst = "$year-01-01";
$yearlast= "$year2-12-31";
if($_SESSION['projectUserType'] == 1 or $_SESSION['projectUserType'] == 4)
{
if($search == 1 ) { //latest added
$querys = "SELECT p.* FROM publication p left join pub_author a on p.id=a.pub_id where p.private = '0' order by p.year ASC limit 1";
} elseif($search == 2){
$querys = "SELECT p.* FROM publication p left join pub_author a on p.id=a.pub_id where p.private = '0' and p.year>='$yearfirst' and p.year<='$yearlast'";
} else {
$querys = "SELECT p.* FROM publication p left join pub_author a on p.id=a.pub_id where p.private = '0'";
}
}
elseif($_SESSION['projectUserType'] == 3) {
$dep = $_SESSION['userDepartmantId'];
if($search == 1 ) { //latest added
$querys = "SELECT p.* FROM publication p left join pub_author a on p.id=a.pub_id where p.private = '0' and pub_department_id='$dep_id' order by p.year ASC limit 1";
} elseif($search == 2){
$querys = "SELECT p.* FROM publication p left join pub_author a on p.id=a.pub_id where p.private = '0' and p.year>='$yearfirst' and p.year<='$yearlast' and pub_department_id='$dep_id'";
} else {
$querys = "SELECT p.* FROM publication p left join pub_author a on p.id=a.pub_id where p.private = '0' and pub_department_id='$dep_id'";
}
}
elseif($_SESSION['projectUserType'] == 5){
$deps = $_SESSION['userDepartmantId'];
$query = "SELECT * from uni_department where id='$dep_id'";
$faculties = mysqli_query($link, $query);
while($a = mysqli_fetch_object($faculties))
{
$fac_id = $a->faculty_id;
}
$query = "SELECT * from uni_department where faculty_id ='$fac_id'";
$faculties = mysqli_query($link, $query);
while($a = mysqli_fetch_object($faculties))
{
$facDeps .= $a->id . ',';
}
$ids = rtrim($facDeps,",");
if($search == 1 ) { //latest added
$querys = "SELECT p.* FROM publication p left join pub_author a on p.id=a.pub_id where p.private = '0' and and pub_department_id IN ($ids) order by p.year ASC limit 1";
} elseif($search == 2){
$querys = "SELECT p.* FROM publication p left join pub_author a on p.id=a.pub_id where p.private = '0' and p.year>='$yearfirst' and p.year<='$yearlast' and pub_department_id IN ($ids)";
} else {
$querys = "SELECT p.* FROM publication p left join pub_author a on p.id=a.pub_id where p.private = '0' and pub_department_id IN ($ids)";
}
}
else{
echo '<script type="text/javascript">';
echo 'window.location = "unauthorized.php"';
echo '</script>';
}
$results5 = mysqli_query($link, $querys);
$num_rows5 = mysqli_num_rows($results5);
echo ' '.$num_rows5;
?>
这是一般表格代码：
<form id="formValidation" action="publication_search_list2.php" method="post" enctype="multipart/form-data" >
<fieldset>
<div style="display:block; padding:20px; background-color:#f5f5f5;">

尝试设置填充2个或更多输入的情况，即
if($author_is_filled){
$sql= 'Select ...from ... where...';
if($search_range){
$sql .= 'and range = '.$search_range;
}
if($date1){
$sql .= 'and date1 ="'.$date1.'"';
}
//...
}
这样你可以做一个单独的SQL。 =）
