Failed to load resource: the server responded with a status of 404 Not Found
Question
I'm new to Wordpress and Ajax and dont really know how to solve this problem, so any help would be appreciated.
I am working on a Wordpress Theme, where all students from a database are displayed in a table:
<?php
get_header();
if(have_posts()):
while(have_posts()) : the_post(); ?>
<article class="post page">
<a href="<?php the_permalink(); ?>"><?php the_content(); ?>
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.2.0/jquery.min.js"></script>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" />
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>
<style>
}
img {
vertical-align: middle;
}
table {
border-collapse: collapse;
width: 100%;
border-spacing: 50px 0;
text-align: center;
}
.hover:hover{
background-color: antiquewhite;
}
td{
padding: 10px;
}
.aligncenter{
text-align: center;
}
div.scroll {
position: static;
width: 700px;
height: 400px;
overflow: scroll;
overflow-x: hidden;
}
a {
text-decoration: none;
}
</style>
</head>
<body>
<div class="scroll"><a href="<?php the_permalink(); ?>"><?php the_content(); ?> </a>
<?php
$mysqli = NEW MySQLi('localhost','root','','wp_db');
if(isset($_GET['order'])){
$order = $_GET['order'];
}else{
$order = 'name';
}
if(isset($_GET['sort'])){
$sort = $_GET['sort'];
}else{
$sort ='ASC';
}
$result = $mysqli->query("SELECT * FROM wp_absolventen ORDER BY $order $sort");
$image = $row['bild'];
if($result->num_rows > 0){
$sort == 'DESC' ? $sort = 'ASC' : $sort ='DESC'; // short IF statements
?>
<div class="table-responsive" style=overflow-x:auto;>
<table class="table table-bordered">
<?php
echo "
<th></th>
<th class='aligncenter'>
<a href='?order=name&&sort=$sort'>Name</a></th>
<th class='aligncenter'><a href='?order=geburtsdatum&&sort=$sort'>Geburtsdatum</a></a></th>
<th class='aligncenter'><a href='?order=stadt&&sort=$sort'>Wohnort</a></th>
";
?>
<?php
while($rows = $result->fetch_assoc())
{
$name = $rows['name'];
$geburtsdatum= $rows['geburtsdatum'];
$stadt = $rows['stadt'];
$p='<img src="data:image/jpg;base64,' . base64_encode( $rows['bild'] ) . '"/>';
$id = $rows['id'];
?>
<tr class='hover'>
<td> <?php echo $p; ?></td>
<td><input type="button" name="view" value="<?php echo $name; ?>" id="<?php echo $row["id"]; ?>" class="btn btn-info btn-xs view_data" /></td>
<td><?php echo $geburtsdatum; ?></td>
<td><?php echo $stadt; ?></td>
</tr>
<?php
}
}else{
echo "No records returned.";
}
?>
</table>
</div>
</body>
</html>
</article>
<div id="dataModal" class="modal fade">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<h4 class="modal-title">Employee Details</h4>
</div>
<div class="modal-body" id="employee_detail">
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
<script>
$(document).ready(function(){
$('.view_data').click(function(){
var employee_id = $(this).attr("id");
$.ajax({
url:"select.php",
method:"post",
data:{employee_id:employee_id},
succes:function(data){
$('#employee_detail').html(data);
$('#dataModal').modal("show");
}
});
});
});
</script>
<?php
endwhile;
else :
echo '<p>No contect found</p>';
endif;
get_footer();
?>
So far so good, but when you click on a students name, it should open a bootstrap modal, where the information about the student are displayed (fetched from Database).
<script>
$(document).ready(function(){
$('.view_data').click(function(){
var employee_id = $(this).attr("id");
$.ajax({
url:"select.php",
method:"post",
data:{employee_id:employee_id},
succes:function(data){
$('#employee_detail').html(data);
$('#dataModal').modal("show");
}
});
});
});
</script>
This is the function that calls another php file (select.php),opens the modal and gets the information from the database. The select.php file:
<?php
if(isset($_POST["employee_id"]))
{
$output = '';
$connect = mysqli_connect("localhost", "root", "", "wp_db");
$query = "SELECT * FROM wp_absolventen WHERE id = '".$_POST["employee_id"]."'";
$result = mysqli_query($connect, $query);
$output .= '
<div class="table-responsive">
<table class="table table-bordered">';
while($row = mysqli_fetch_array($result))
{
$output .= '
<tr>
<td width="30%"><label>Name</label></td>
<td width="70%">'.$row["name"].'</td>
</tr>
';
}
$output .= "</table></div>";
echo $output;
}
?>
But when I try to click on the students name, the modal doesnt open, instead I get this 404 error: Failed to load resource: the server responded with a status http://localhost/wordpress/sample-page/select.php of 404 (Not Found). Both files are in the same folder.
The code works when its not in a wordpress folder.

I answered similar question from a different thread... Basically, establish/write a simple php file and if you can access it directly via browser, then you call it via ajax.... The set up is prefixing the file name with page-"title-of-page".php, then create a blank page with "title-of-page" similar to the aforementioned convention, and then set up your permalinks url. Here's the other thread .

Try sending the file path using data attribute so below line
<td><input type="button" name="view" value="<?php echo $name; ?>" id="<?php echo $row["id"]; ?>" class="btn btn-info btn-xs view_data" /></td>
can be
<td><input type="button" name="view" value="<?php echo $name; ?>" id="<?php echo $row["id"]; ?>" class="btn btn-info btn-xs view_data" data-file="<?php echo get_template_directory() . '/select.php'; ?>" /></td>
And below line,
url:"select.php",
can be
url: $(this).data('file'),
I haven't tested from my side. But this is just an idea for your way of code.
EDITED:
<td><input type="button" name="view" value="<?php echo $name; ?>" id="<?php echo $row["id"]; ?>" class="btn btn-info btn-xs view_data" /></td>
can be
<td><input type="button" name="view" value="<?php echo $name; ?>" id="<?php echo $row["id"]; ?>" class="btn btn-info btn-xs view_data" data-file="<?php echo get_template_directory_uri() . '/select.php'; ?>" /></td>
And below line,
url:"select.php",
can be
url: $(this).data('file'),

Saving the php file as page-select.php and creating a blank page named "select" in the Wordpress pages did the trick! Although instead of url: "/select" I used only "select" and it worked! Thanks again for your time Anthony and Thirumani guhan!:)
