You forgot to add what part is not working well. It appears this is not the complete code, as there is no mysql_connect in this snippet.

i need to create a reminder for for my users,if i input a date for a reminder,it echos back this,["1324034507",instead of a normal date and this
"There are no reminders for vehicle"] even when i change the date to so as to get a reminder.
This is a picture of my mysql db.

You can format your date with the date() function. What is the column type for your date columns ?

Thank you for your help,i think i have clean up some part of the code.I am very regretful. I still have some errors showing up.This is the error message

Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in E:\xampp\htdocs\msl\admin\userindex\serxbh738hss.php on line 156

And this is the code below:

<?php
                                        
                       $current_date = strtotime('now');
		       $due_end_date = 60 * 60 * 24 * 7;
		       $last_startdate = last_startdate;
		       $vtype = vtype;
			$vreg = vreg;    
			$dept = dept;
			$name_mech = name_mech;
			$com_name = com_name;
									
									
										
$sql_query = "SELECT * FROM sre_log WHERE current_date >= '$due_end_date-$current_date' ORDER by vreg";

		$result = mysql_query($sql_query);
		//$num_results = mysql_num_rows($result);
		while ($row = mysql_fetch_array($result))

		// while ($sre_log = mysql_fetch_array($sre_log))
		
                    {
											
			$id = $row['id'];
			$vtype = $row['vtype'];
			$vreg = $row['vreg'];
			$current_date = $row['current_date'];
			$dept = $row['dept'];

			$com_name = $row['com_name'];
									
			}
										
			if ($current_date != $due_end_date) 
										
			{
				echo "<h3 class=\"update\">";
				echo "<em>There are no reminders for vehicle # $vreg</em>";
				echo "<em style=\"font-size:12px; float:right;\">Next Service Dued $vreg[$due_end_date]</em>";

					}

				}
										
					else
										
					{
						echo "Pls. enter data for vehicle";
					}
                                            ?>

Your query is wrong. I suggest you move the subtract of your two variables (line 14) into a new variable on line 13, and use that new variable in your query.

[accra]

Can you pls. give an example,Thanks.

[reco21]

$endminuscurrent = $due_end_date-$current_date;
$sql_query = "SELECT * FROM sre_log WHERE current_date = '$endminuscurrent' ORDER by vreg";
