如何添加搜索功能以过滤名称列表

Question

I had retrieved a list of employees from the database using php code and I want to add a search functionality to filter the names.

How can I do this using js or php? I got struct in this from last one week, searched online but unable to find the solution.

<input type="text" id="myInput" onkeyup="myFunction()" placeholder="Search for names.." title="Search Name">

<ul id="myUL" class="contacts-list">
  <?php
  $status=1;
  $sql1 =  $dbh->prepare("SELECT * FROM employee WHERE status='$status'");
  $sql1->execute();

  if($sql1->rowCount() > 0) { 
    while($row = $sql1->fetch(PDO::FETCH_ASSOC)){
  ?>
      <li>
        <a href="messages.php?employee_id=<?php echo $row['employee_id']; ?>">
          <div class="contacts-list-info">
            <span class="contacts-list-name">
          <?php echo $row['fname']." ".$row['lname']; ?>
            <small class="contacts-list-date pull-right">
              <?php if($row['status'] == '1') { echo 'Online'; } else { echo 'Offline'; } ?>
            </small>
          </span>
            <span class="contacts-list-msg">
            <?php echo $row['role']; ?>
          </span>
          </div>
        </a>
      </li>
  <?php
    }
  }
  ?>
</ul>

Answer 1

If you want to filter just on the client side, you can do something like this:

Get all contacts (eg li tags) and apply a filter based on the users input.

 function search() { var input = document.getElementById('search').value.toLowerCase(); var contacts = document.getElementsByTagName('li'); for (var i = 0; i < contacts.length; i++) { if (contacts[i].innerText.toLowerCase().includes(input)) { contacts[i].style.display = "block"; } else if (!contacts[i].innerText.toLowerCase().includes(input)) { contacts[i].style.display = "none"; } } } 

 <input type="text" id="search" onkeyup="search()"> Enter something to filter <br> <ul> <li>Some Dude</li> <li>Some Dudine</li> <li>John Doe</li> <li>Erica Doe</li> </ul> 

Answer 2

You can use like query as below:

Select * from employee where status LIKE '%$status%';

As per your query you can get employee status from database.

Hope this works for you.

What do you want to do. If you want suggestion box like in search input field than u can simple use ajax request to fetch suggestion form DB and add typehead js library and than paste following code.

$('#id').typeahead({
                ajax: {
                    url: '../employeeList',
                    method: 'post',
                    triggerLength: 1
                }
            });

Here is a working exapmle for filtering in client-side using your structure.

 document.getElementById("myInput").addEventListener('keyup', function() { var input = this.value.toLowerCase(); var people = document.getElementsByClassName("contacts-list-info"); for (var i of people) { if (i.innerText.toLowerCase().includes(input)) { i.closest("li").style.display = "list-item"; } else { i.closest("li").style.display = "none"; } } }); 

 <input type="text" id="myInput" placeholder="Search for names.." title="Search Name"> <ul id="myUL" class="contacts-list"> <li> <a href="messages.php?employee_id=1"> <div class="contacts-list-info"> <span class="contacts-list-name"> Test Test <small class="contacts-list-date pull-right"> Offline </small> </span> <span class="contacts-list-msg"> Manager </span> </div> </a> </li> <li> <a href="messages.php?employee_id=1"> <div class="contacts-list-info"> <span class="contacts-list-name"> Second Test <small class="contacts-list-date pull-right"> Online </small> </span> <span class="contacts-list-msg"> Manager </span> </div> </a> </li> <li> <a href="messages.php?employee_id=1"> <div class="contacts-list-info"> <span class="contacts-list-name"> Third Test <small class="contacts-list-date pull-right"> Online </small> </span> <span class="contacts-list-msg"> Employee </span> </div> </a> </li> <li> <a href="messages.php?employee_id=1"> <div class="contacts-list-info"> <span class="contacts-list-name"> Fourth Test <small class="contacts-list-date pull-right"> Offline </small> </span> <span class="contacts-list-msg"> Team member </span> </div> </a> </li> </ul>
