SELECT multiple WHERE in same column - php

Question

I want choose month and year from the same column. How can I separate month and year from the column?
<label>Bulan :</label>
<select name="month">
<option value=""></option>
<option value="1">Januari</option>
<option value="2">Februari</option>
<option value="3">Mac</option>
<!-- ... -->
</select>
<label>Tahun :</label>
<select name="year">
<option value=""></option>
<option value="2017">2017</option>
<option value="2016">2016</option>
</select>
<input type="submit" value="Hantar" >
<?php
if(isset($_POST['year']) && ($_POST['month']))
{
$tarikh = mysql_real_escape_string($_POST['month']);
$tarikh = mysql_real_escape_string($_POST['year']);
I am running this query
$query ="SELECT * FROM pelanggan
WHERE (MONTH(tarikh) = '$tarikh')
and (YEAR(tarikh) = '$tarikh')";
Why doesn't the output display? What is wrong with the above query?

Answer 1

in query string you use same variable for month and year
add different variable names in
$tarikhMonth = mysql_real_escape_string($_POST['month']);
$tarikhYear = mysql_real_escape_string($_POST['year']);
and
$query ="SELECT * FROM pelanggan
WHERE (MONTH(tarikh) = '$tarikhMonth')
and (YEAR(tarikh) = '$tarikhYear')";

Answer 2

You are overwriting your $tarikh variable. Naming them $month and $year should work.
I would use PDO instead of trying to escape strings manually as well.

Answer 3

You need to have different variable names for the month and year. Try this
<label>Bulan :</label> <select name="month">
<option value=""></option>
<option value="1">Januari</option>
<option value="2">Februari</option>
<option value="3">Mac</option>...
</select><label>Tahun :</label> <select name="year">
<option value=""></option>
<option value="2017">2017</option>
<option value="2016">2016</option>
</select><input type="submit" value="Hantar" ></td>
<?php
if(isset($_POST['year']) && ($_POST['month']))
{
$tarikh_month = mysql_real_escape_string($_POST['month']);
$tarikh_year = mysql_real_escape_string($_POST['year']);
$query ="SELECT * FROM pelanggan
WHERE (MONTH(tarikh) = '$tarikh_month')
and (YEAR(tarikh) = '$tarikh_year')";
