how can i make this dynamic BETWEEN '2014-07-01 00:00:00' AND '2014-07-31 23:59:59'";
Question
Im still a noob php programmer. Please help me with my problem. I was trying to code a timeline. Im stuck at the query part. Let's say i have a select element with the months in it. If ever I want to select the July, the timeline displays all the events listed on July 2014. What if its already 2015? my query remains static (BETWEEN '2014-07-01 00:00:00' AND '2014-07-31 23:59:59'";)
<?php
mysql_connect("localhost","root","") or die(mysql_error());
mysql_select_db("prototype") or die(mysql_error());
if(isset($_POST['submit'])) {
if($_POST['month'] == 'July') {
$sql = "SELECT * FROM events WHERE event_schedule BETWEEN '2014-07-01 00:00:00' AND '2014-07-31 23:59:59'";
$query = mysql_query($sql);
while ($row = mysql_fetch_array($query)) {
echo "Title:".$row['event_title']."<br>";
echo "Description:".$row['event_description']."<br>";
echo "Schedule:".$row['event_schedule']."<br>";
echo "Date Created:".$row['date_created']."<br>";
echo "Posted By:".$row['posted_by']."<br>";
}
}
if($_POST['month'] == 'August') {
$sql = "SELECT * FROM events WHERE event_schedule BETWEEN '2014-08-01 00:00:00' AND '2014-08-31 23:59:59'";
$query = mysql_query($sql);
while ($row = mysql_fetch_array($query)) {
echo "Title:".$row['event_title']."<br>";
echo "Description:".$row['event_description']."<br>";
echo "Schedule:".$row['event_schedule']."<br>";
echo "Date Created:".$row['date_created']."<br>";
echo "Posted By:".$row['posted_by'];
}
}
}
echo date("F Y");
?>
<html>
<form method="post">
<select name="month">

You can try something like this
$sql = "SELECT * FROM events WHERE event_schedule LIKE '%-07-%'";

You can embed PHP vars into your query text. So you can pull the current year with date():
$queryYear = date('Y');
$sql = "SELECT * FROM events WHERE event_schedule BETWEEN '{$queryYear}-07-01 00:00:00' AND '{$queryYear}-07-31 23:59:59'";

As already been commented you should consider in changing your code to work with MYSQLi or PDO functions. Mysql_* functions is deprecated.
As for your answer I would recomment two things.
1 - Add the month values on your html form
<option value="1">January</option>
<option value="2">February</option>
<option value="3">March</option>
<option value="4">April</option>
...
2 - Change your PHP with just on set of code, you don't need to test each case and repeat your code. Something like this:
if(isset($_POST['submit'])) {
/*AGAIN THIS IS NOT RECOMMENDED AS IT CAN BE SQLInjected*/
$sql = "SELECT *
FROM events ";
if ($_POST['month']!=''){
$sql .= " WHERE extract(YEAR from event_schedule) = extract(YEAR from now())
and extract(MONTH from event_schedule) = $_POST['month']";
}
$query = mysql_query($sql);
while ($row = mysql_fetch_array($query)) {
echo "Title:".$row['event_title']."<br>";
echo "Description:".$row['event_description']."<br>";
echo "Schedule:".$row['event_schedule']."<br>";
echo "Date Created:".$row['date_created']."<br>";
echo "Posted By:".$row['posted_by']."<br>";
}
}
