MySQL数据库中没有任何显示

I have a problem displaying my information in the database using phpmyadmin. I have 2 files (form.php and connect.php), it says it's connected to the database but nothing shows up in my database.

Is there any solution for that? I spent almost a whole day trying to resolve that.

Here's connect.php:

<?php
$mysql_host='localhost';
$mysql_user='root';
$mysql_password=''; **i don't have a password.

mysql_connect($mysql_host,$mysql_user,$mysql_password)

echo"connection sucess";

$link = mysqli_connect("localhost","root","") or die ("Couldn't not connect");
mysqli_select_db($link, "cooperative_db");

if (!$link) {
    die('Could not connect: ' . mysql_error());
}

echo "Successfully connected 
";

$FIRST_NAME = $_POST['FIRST_NAME'];
$LAST_TIME = $_POST['LAST_NAME'];
$CIVIC_NUMBER = $_POST['CIVIC_NUMBER'];
$STREET = $_POST['STREET'];
$CITY = $_POST['CITY'];
$PROVINCE = $_POST['PROVINCE'];
$POSTAL_CODE = $_POST['POSTAL_CODE'];
$COUNTRY = $_POST['COUNTRY'];
//$TELEPHONE = $_POST['TELEPHONE'] . $_POST['TELEPHONE'] . $_POST['TELEPHONE'];
$INCOME = $_POST['INCOME'];
//$INCOME_SOURCE = $_POST['element_6_1'] . $_POST['element_6_2'] . $_POST['element_6_3'] . $_POST['element_6_4'] .
//$_POST['element_6_5'];

$sql = "INSERT INTO candidat(FIRST_NAME, LAST_NAME, CIVIC_NUMBER, STREET, CITY, PROVINCE, POSTAL_CODE, COUNTRY, INCOME) VALUES ('$FIRST_NAME', '$LAST_TIME', '$CIVIC_NUMBER', '$STREET','$CITY', '$PROVINCE', '$POSTAL_CODE', '$COUNTRY', '$INCOME')";

?>

It seems like you may have many issues in your code. Let's start step by step.

I am not sure if that: "**i don't have a password." is actually inside your code, so change it first of all to //i don't have a password..
Now, in the second picture you showed us, it only echo 1 line instead of two, and inside your code you actually have two lines that should echo a result.
echo"connection sucess"; and echo "Successfully connected ";

This could be due to the fact that you forgot a ; in the line right before the first echo.
mysql_connect($mysql_host,$mysql_user,$mysql_password);

May I ask you why are you using both mysql, and mysqli? If it's just for testing, there's no harm in it, plus you should know that mysql is deprecated and no longer supported or updated, you better just use mysqli, please refer to this post Why shouldn't I use mysql_* functions in PHP?.

The first picture shows that you don't have a table named candidat, yet in your code you have this: INSERT INTO candidat. Maybe you wanted this to be INSERT INTO cooperative_table instead?
Please make those small fixes, and tell us your result.

Edit: I forgot to mention, just like tadman commented, you better be aware of the SQL Injection bugs you have and fix them accordingly.
