Hi everyone! I have a problem in My system, the problem is when I send My data I leave this error, and I don't know why it happens:

Fatal error: Uncaught Error: Call to undefined function mysql_query() in C:\xampp\htdocs\clinica\dise\searchData.php:8 Stack trace: #0 {main} thrown in C:\xampp\htdocs\clinica\dise\searchData.php on line 8

And this is my code PHP:

		<?php  
include("../conex.php"); 

$pass=$_POST['pass'];
$id=$_POST['ci'];

$conexion = mysqli_connect("localhost","root","", "clini") or die("no hay conexion");
$register= mysql_query("SELECT * FROM usuario WHERE pass='$pass' AND identificacion='$id'");

 while($login=mysql_fetch_array($register)){
	 echo $login['id']." ".$login['name']." ".$login['last']." ".$login['nameDad']." ".$login['nameMom']."
	 ".$login['tipoIdentificacion']." ".$login['identificacion']." ".$login['telefono']." ".$login['email']." 
	 ".$login['address']." ".$login['born']." ".$login['rango']." ".$login['estadoC']." ".$login['sex']."
	 ".$login['pass']." ".$login['fechaReg'];
 }

?>

Your code is vulnerable to SQL Injection[^]. NEVER use string concatenation to build a SQL query. ALWAYS use a parameterized query.

You're storing passwords in plain text. Don't do that.

PHP even has built-in methods to help you do the right thing.

But leave other error is this:
Warning: mysqli_query() expects at least 2 parameters, 1 given in C:\xampp\htdocs\clinica\dise\searchData.php on line 8

Fatal error: Uncaught Error: Call to undefined function mysql_fetch_array() in C:\xampp\htdocs\clinica\dise\searchData.php:10 Stack trace: #0 {main} thrown in C:\xampp\htdocs\clinica\dise\searchData.php on line 10

You are missing the connection parameter in your call to mysqli_query.
You need to change all your calls to use the correct function names.

The link I gave you above is at the MySQL documentation site, so you should go there to check the correct function names and parameter requirements.
