Multiple Drop down list to filter MySQL Tables

[kelvin24]

I want to filter my table in MySQL by many categories but once I'd finished the other drop down list the IF statements of the first Drop down was not able to filter the table. The If Statement of the second filter was the one recognized. Here's the code.Please

Code: Select all

<div>
   <form <?php echo $_SERVER['PHP_SELF']; ?>' method='post' name='form_filter'><br /><br />
    <select name="Dlrdrop">
       <option value="Alldlr">Dealer</option>
        <option value="HGH">HGH</option>
        <option value="HBI">HBI</option>
   </select><input type='submit' value = 'Filter'>
           <select name="Monthdrop">
     <option value="Month">Month</option>
     <option value="January">January</option>
     <option value="February">February</option>
     <option value="March">March</option>
     <option value="April">April</option>
     <option value="May">May</option>
     <option value="July">June</option>
     <option value="August">August</option>
     <option value="September">September</option>
     <option value="October">October</option>
     <option value="November">November</option>
     <option value="December">December</option>
   </select>
    <input type='submit' value = 'Filter' />
   <form <?php echo $_SERVER['PHP_SELF']; ?>' method='post' name='form_filter'>
   <br /><br /><br /><br /><br /><br />
</div>
