Issue displaying mysql data with php code/ajax

[Galgu]

Hello everyone,

I begin in everything web related but I have been programming for years. I tried to code something simple : small Mysql DB (works fine) and to begin a search bar to browse data. I adapted a code that I understood provided here : https://www.cloudways.com/blog/live-search-php-mysql-ajax/. Base principle is simple :  as you type in your query, it will pass the text to script.js  that will forward this request to ajax.php file. In the ajax.php, a javascript function named “fill()” will pass the fetched results. This function will also display the result(s) into “display” div in the  “search.php” file.

The problem is that when I type anything it displays, below the search bar, at the moment I type a character:

Quote

 

'; //Fetching result from database. while ($Result = MySQLi_fetch_array($ExecQuery)) { ?>

")'>

 

instead of the actual answer from my database (no error in the browser console).

I tested the SQL query + the user I provide and everything seems fine.

Any clue what could be the root cause ? I strongly suspect a mistake in the code as I already corrected one (script.js instead of scripts.js) but I really cannot figure out where.

Thanks in advance,

 

 problematic code (ajax.php):

 

<?php

//Including Database configuration file.

include "db.php";

//Getting value of "search" variable from "script.js".

if (isset($_POST['search'])) {

//Search box value assigning to $Name variable.

   $Name = $_POST['search'];

//Search query.

   $Query = "SELECT Name FROM search WHERE Name LIKE '%$Name%' LIMIT 5";

//Query execution

   $ExecQuery = MySQLi_query($con, $Query);

//Creating unordered list to display result.

   echo '

<ul>

   ';

   //Fetching result from database.

   while ($Result = MySQLi_fetch_array($ExecQuery)) {

       ?>

   <!-- Creating unordered list items.

        Calling javascript function named as "fill" found in "script.js" file.

        By passing fetched result as parameter. -->

   <li onclick='fill("<?php echo $Result['Name']; ?>")'>

   <a>

   <!-- Assigning searched result in "Search box" in "search.php" file. -->

       <?php echo $Result['Name']; ?>

   </li></a>

   <!-- Below php code is just for closing parenthesis. Don't be confused. -->

   <?php

}}


?>

</ul>

What is 'MySQLi_query'? Did you write your own function?  PHP is case sensitive. I am guessing you meant 'mysqli_query'.

An AJAX script returns everything in it's response that a normal script would send to the browser.

Try calling ajax.php as a non-ajax request (in you browser as you would

any other php script). What you see is what it would return in its response.

Not when it comes to function names.
