Question

I want to delete records from mysql using php

the field name: Week

Week records values as below:

200801
200802
200803
200804
200805
etc

I created TextField named “tYear”, user will insert first 4 numbers from the left and sql statement should remove all the records starting with them, example … if the user insert 2008 all the above records as they starting with 2008 should be removed.

I am using sql statement as below but it’s not working

$sql= "DELETE from sites WHERE Week like '". $_POST['tYear']."'";
$results = mysql_query($sql);

Answer 1

your query is :
$sql= “DELETE from sites WHERE Week like ‘”. $_POST[‘tYear’].”‘”;

and with like in mysql you have to use like '%%' or like '%' for so use :

$sql= "DELETE from sites WHERE 
        Week like '%". mysql_real_escape_string($_POST['tYear'])."%'";
